I went for a six-monthly eye check up today and got some good news. About 10 years ago I was told I had glaucoma. Today I discovered that it isn't glaucoma, just high pressure which is easily controlled with the eye drops I have been using all along for glaucoma.
Darn - wish it was a Glaucous Gull, not a Herring Gull, since that would have let me give the photo an even cheesier title!

My shasta daisies are soaked by yesterday's rain. Taken this morning, bright and early but posting a little late to the group. I accompanied my dad to an eye specialist appointment at the hospital today. All is fine, but he is just getting older and is troubled with glaucoma.
Thanks for your visit! HLCoF!

I hope everyone has had a wonderful beginning to 2023. I was not so lucky, after experiencing severe eye pain and blurred vision I ended up in the emergency room before 5 o'clock in the morning, it looks like acute angle glaucoma, the official diagnosis should come by the end of the week, I feel much better tonight so far. last night typing anything was impossible.
This is my lovely dog "Nozomi" wearing my handmade mouse costume.
Her right eye is blind because of Glaucoma.
My psyche prefers a set of three connected /3 similar photographs in a sequence whenever possible but just one a day to be fair to anyone liking something to comment on. So here is bird number 3 taken in roughly the same area as the previous two. I am afraid I shall be slow to leave comments because I am home after 4 hours extensive testing of my eyes at the Neuro -Ophthalmic surgery at my local hospital.
Still no closer to finding out the cause of my problem despite scans, pressure testing, examinations of both eyes x 2
All of this today....
Only to be referred to the Glaucoma clinic... this after the first test was for Glaucoma and where I was told I didn't have signs of Glaucoma. I googled my symptoms on reaching home, which at the beginning of this eye problem starting over a year ago suggested to me 'night blindness ' my Optician then an Ophthalmologist both said I don't have this condition but my symptoms are exactly that...I had been looking at American sites because the NHS in the UK don't appear to recognise it as an actual real 'thing' if anyone I follow suffers from this I would be interested in what treatment is available.. the suggestion the consultant thought possible being removal of the tiny early cataracts and drops for Glaucoma ?????
Every year, we have a dog Halloween party at a local park. This year, 50 fellow dogs gathered in costume👻👿🎃
There were so many dogs that my blind dog got a little scared. So, we left the park little bit earlier.
Betagan - a medicine used to control glaucoma. This has no preservative so after use, the plastic container has to be discarded. I suppose that we humans have to accept that there will be some some single use items we can't do without. I recycle these so I hope they go to be melted down and made into other things.

Spring of 2019 I hurt my back, little did I know that was only the tip of the iceberg. I had much more wrong than a pulled back muscle. The doctors would discover that I had a nasty bacterial infection, diabetes, and glaucoma in one eye. I was a mess. I spent two months in hospital. I lost from 180lbs down to 133 lbs. I could not really do anything for myself.
Skip forward a year into recovery and walking is a big deal to me. So every morning I grab my rollator and take a walk. Some mornings it is slow and painful, and others I am full of curiosity. I like taking my camera because I never know what I may find.
This morning I found this wonderful Sunflower in bloom. I stopped to create an image. This pause in my walk opened up a conversation with my neighbour. The conversation reminded me that photography has always been my given way to communicate. It is also the way I prefer to meet new people because it opens in a pleasant way.
A walker, a camera and a curious mind...What a wonderful way to start the day.
I'm taking a bit of time out yesterday i lost my little girl my best friend Trixie and i'm heartbroken . A year ago i found out she had a tumor on her liver and nothing could be done to help her as she had a bad heart murmur which was found when she lost her eye to glaucoma . Trixie was such a brave girl ive been in awe of her . I love her so much i don't know how i'll cope without her she was my world . Take care my friends hugs and much love to you all ❤️❤️❤️
Yay, I'm back from my stay in Manchester Eye Hospital! I know some of my flickr buddies have been curious so, in brief, I needed to have drainage reconstruction surgery (a Trabeculectomy) because I have a bad case of Glaucoma. So, I have a new bionic eye but my requests for X Ray vision fell on deaf ears - which is a shame because I was looking forward to that bit!
This photo was never taken with any thought of me on the operating table but when I was going through photos to post I just thought yep, that sums it up! ! It's actually a stone sculpture that lies face up in shallow water at Trentham Gardens.
Anyway, I now have two weeks of doing nothing, another two weeks of doing very little and then two months of taking it easy so my photography is going to be a little curbed, I have a few photos in the pot to be going on with and then I'll see how it goes. I'll be visiting your pages though - no restrctions with that!
"Vanda coerulea, commonly known as blue orchid, blue vanda or autumn lady's tresses,
Species native to India, Burma and Thailand. An amazing orchid with one of the closest flower colors to true blue! . When in bloom, this orchid shows off deep purple-to-blue flowers that span 4" to 6" across. To make matters more interesting, the colors intensify from a pale purple to a rich indigo over the course of 10 days.
The flower's juice is used as eye drops against glaucoma, cataract and blindness. Active ingredients of Vanda coerulea may fight against the visible signs of ageing skin."
I went back to the eye doctor yesterday and he now says there was probably some nerve damage from the glaucoma, before we got the pressure down. So it's possible I'll never be able to see well with the left eye. He says he sees no reason why the right still tires so easily, although the pressure is now slightly elevated. So now I have eyedrops for the right eye also. Hopefully I'll have time later to look at pictures. HAVE A WONDERFUL DAY!!!!
Hi my friends!
Update about my eyes: they are worse day by day and I couldnt have the glaucoma surgery yet because I'm a little sick with the flu.I'm still in home 24 hours a day because I can't walk alone, but tonight I'll go out. Even with the flu!!!

• Fennec fox
• Fénec, feneco, zorro del desierto
The fennec fox (Vulpes zerda) is a small crepuscular fox native to the deserts of North Africa, ranging from Western Sahara and Mauritania to the Sinai Peninsula. Its most distinctive feature is its unusually large ears, which serve to dissipate heat and listen for underground prey.
Its name comes from the species' Arabic name: fanak (فَنَك), which means "little fox".
Scientific classification:
Domain:Eukaryota
Kingdom:Animalia
Phylum:Chordata
Class:Mammalia
Order:Carnivora
Infraorder:Cynoidea
Family:Canidae
Subfamily:Caninae
Tribe:Vulpini
Genus:Vulpes
Species:V. zerda
The fennec is the smallest fox species. Its coat, ears, and kidney functions have adapted to the desert environment with high temperatures and little water. It mainly eats insects, small mammals and birds. The fennec has a life span of up to 14 years in captivity and about 10 years in the wild. Its main predators are the Verreaux's eagle-owl, jackals and other large mammals. Fennec families dig out burrows in the sand for habitation and protection, which can be as large as 120 m2 (1,300 sq ft) and adjoin the burrows of other families. Precise population figures are not known but are estimated from the frequency of sightings; these indicate that the fennec is currently not threatened by extinction. Knowledge of social interactions is limited to information gathered from captive animals. The fennec's fur is prized by the indigenous peoples of North Africa, and it is considered an exotic pet in some parts of the world.
In captive fennec foxes, glaucoma is a common eye disease. Its prevalence in captive animals is due to factors like genetic predisposition (limited genetic diversity), environmental stress, lack of exercise, and age (captive animals often live longer).

As if when morning arrived
the day seemed beset by glaucoma,
the edges of everything a soft blur,
the light hazy, sounds muffled,
headlights a diffuse glow, the world
half-erased beyond a block and no matter
what anyone said at the corner café
about the head-on collision at the edge
of town between the school bus
and a stray cow, the fog was a message
not to be ignored, the air sodden
with the taste of diesel fuel, the mist
lingering past noon, a mild blindness
no one was sad to see finally lift.

Several people have asked if I plan to use marijuana for my glaucoma. There are currently eleven states that allow this and Illinois is not one. I doubt if I would be tempted if it was legal! By the way, this is actually hemp, known around here as ditchweed. I'm told it used to be grown to make rope. Now it grows wild anywhere that doesn't get mowed regularly. Pressure is higher in my left eye and I have more eye drops that are supposed to help, but nothing for pain. Thanks For Prayer!

"Notti più buie del buio e giorni uno più grigio di quello appena passato. Come l'inizio di un freddo glaucoma che offuscava il mondo."

My Stray Cat has developed Glaucoma and is not willing to accept any medical help.I feel sorry for the little trooper for I have eye drops and painkillers and he refuses any help.
A moment after I took this shot I noticed Blue squinting her left eye. Pulling her eyelid back her cornea looked just horrible. I thought it had burst. Put her in the car and off to the vet we went. Without an appointment we had to wait 2 1/2 hours to be seen - extremely frustrating. Her cornea had not burst but the lens/cataract in that eye had detached on the upper portion and was tilting back into her eye. You can notice it in this pic quite clearly. This caused a dramatic increase in pressure within the eye. She is on pain, anti-inflammatory meds and glaucoma drops. When we are able to see the eye specialist they will most likely recommend removing her eye. I don't care that she won't have an eye, she is blind after all, but I'm worried about the surgery at her age. Still, throughout it all, she has never been a burden in any way. Loves and trusts everyone, every situation and setting. The most amazing friend.
My beloved dog Nozomi celebrated her 13th birthday. I made her her crown. It was also very popular with the dog companions I meet at the park.
She lost the sight in her right eye three years ago due to glaucoma. She had been living with one eye, but in August of this year she developed glaucoma in her left eye as well. She can barely see anything now.
She and I and my family are very confused. We are always thinking about how we can make her live comfortably.

I have started to develop glaucoma so I have to put a couple of drops in my eyes each morning
Misty Sunrise in Northumberland.Going through some older Raw images until I receive my glasses this week...short sighted in right and and have to have tests for Glaucoma...finding it very hard to process an image 1 foot away from screen...should get sorted hopefully....need my eyes!
Don't forget to get your eyes checked. I just had my pupils dilated
and a full eye exam. I have to watch for glaucoma which runs in my family.
It means your eyes have too much pressure inside them and
it can damage the optic nerve and so your vision if not treated.
A few years ago my pressure was too high so I have to keep up on it.
This time I checked out just fine.

A boxing Day stroll out to Pew Tor, there was some mist and fog in the area and although finding Beckamoor Cross was easy enough, we missed the easy leat crossing in the fog and had to hang around for a small amount of time while I took a few photos to counter any boredom....
The fog or mist lifted enough to find out path towards Pew Tor and the easy leat crossing. I was blessed with some amazing light that I had never seen before later on and it had me questioning my sanity as I am experiencing a few Glaucoma symptoms and rainbow halos being one of them I had never seen them in daylight before so I took a photograph of it just in case it was be seeing it with crap eyes.
Thankfully, I was seeing the real deal. And I will share the photo at a later date.
I'd had a morning of eye tests for glaucoma, so to celebrate all was fine, and to get some fresh air vI decided to brave the winds and rain and have some fun. I hadn't made a driftwood boat for some time so had a great time picking suitable pieces and constructing it. I had some of Sue's scarves for flags and headed off into the wind. Sadly after two photos the boat ran aground and fell to pieces so I had to swim ashore. Waving Flags is by British Sea Power

WARNING Very sharp thistle-like prickly stems and leaves, so it’s best to wear very thick gloves when handling. White flowers with yellow center are up to 5 inches (13 cm) across and have 6, large, tissue-paper-like petals. From a distance, the flowers look like fried eggs. Stems contain white latex that you can apply to warts moles skin cancer to help eat them away. Considered poisonous when fresh, boiling recommended. The upper part of the plant is sometimes crushed and dried to make a mild sedative, contains a very minute amount of opium so it's a relaxant, helps sleep (all poppies do, even the red and orange ones). The seeds contain toxic alkaloids that sometimes cause glaucoma.

Interesting Facts About Galileo Galilei
Galileo dropped out of university.
Initially, his father sent him to the University of Pisa to study medicine, but Galileo became interested in mathematics and left the university without a degree.
Galileo’s middle finger is on display in a museum.
Around a century after the scientist’s burial, the middle finger of his right hand was removed from his corpse and has been housed at various museums in Italy since then.
Galileo spent his final years under house arrest.
Galileo’s support for heliocentrism put him in direct conflict with the Catholic Church. As punishment, he was first sentenced to life imprisonment and then to house arrest.
The Vatican didn’t admit Galileo was right until just recently.
Only in 1992, Pope John Paul II officially declared that Galileo Galilei was right in his support of heliocentrism and that the Inquisition had made a mistake in imprisoning him.
Four years before death, Galileo became totally blind
Contrary to popular belief, Galileo’s blindness wasn’t caused by his observations of the Sun. Most likely, the cause was a cataract or glaucoma.
Galileo's Breakthrough Observations in Astronomy
Galileo Galilei revolutionized astronomy with his groundbreaking observations of the celestial bodies using a modified telescope. Most of them were published in his book "Sidereus Nuncius" in March 1610.

Galileo Galilei discovered four of Jupiter's moons in 1610. He made observations of Jupiter and its moons over several nights and found that Jupiter was accompanied by four small celestial bodies that orbited around it. This discovery was a breakthrough in the scientific understanding of the Solar System, showing that planets can have their moons. The moons, now known as the Galilean moons, are among the largest in the Solar System. If you have the Sky Tonight app, you can see the current position of the Galilean moons by simply zooming in on Jupiter.
The stars of the Milky Way
Galileo Galilei made a seminal contribution to the understanding of the Milky Way. Before his observations, the Milky Way was generally considered a cloudy band across the sky. Still, Galileo was the first to recognize it as a collection of countless individual stars.
Sunspots
Sunspots are dark areas on the surface of the Sun. Before Galileo's discovery, they were not widely known or studied. Galileo used a telescope to observe the Sun and found it had dark spots on its surface, which he recorded in a series of drawings. This was a major discovery at the time, as the prevailing view was that the Sun was an unchanging object. Galileo's observation of sunspots proved that the Sun was not a perfect celestial body but was subject to change and imperfections.
Lunar librations
Galileo Galilei studied lunar librations, small oscillations in the Moon's apparent position, and was the first to understand the cause of these movements. He observed the Moon with a telescope and made detailed drawings, including its librations, which he recognized were due to the changing perspective from Earth and the orientation of the Moon's surface. Galileo's discoveries advanced our understanding of the Moon and its movement, supporting the heliocentric model of the solar system.

Galileo’s achievements outside astronomy
Galileo Galilei was a renowned astronomer and also a prolific inventor and scientist. Throughout his life, he made numerous contributions to various fields, including physics, mathematics, engineering, and philosophy.
The law of falling bodies
The law of falling bodies, also known as Galileo's law of free fall, states that all objects fall at the same rate, regardless of their mass, as long as air resistance is negligible. He dropped objects of different masses from the Leaning Tower of Pisa and showed that they hit the ground at the same time, disproving the prevailing Aristotelian belief that heavier objects fall faster than lighter ones. The Law of Falling Bodies was a significant step forward in the development of the scientific understanding of motion. It helped lay the foundation for the laws of motion developed later by Sir Isaac Newton.
The basic principles of pendulum
The basic principle of pendulum motion, also known as Galileo's law of pendulum, states that a pendulum will swing back and forth in a regular, repeating pattern, with the time it takes to complete one cycle, or period, being dependent only on the length of the pendulum and the acceleration due to gravity. This discovery laid the foundation for the development of accurate timekeeping devices such as clocks. In addition, it led to a deeper understanding of the laws of motion and the behavior of oscillating systems.
The theory of parabolic trajectories
Galileo Galilei's theory of parabolic trajectories, also known as his law of projectiles, states that a projectile's path under gravity is a parabolic curve. He showed that a projectile's horizontal and vertical motion can be described separately and that its trajectory is a parabolic curve. This was a crucial step in understanding motion and paved the way for Sir Isaac Newton's laws of motion. Galileo's theory remains essential in explaining the motion of projectiles, including objects in satellite orbits, sports projectiles, and missiles.
What didn't Galileo Galilei do?
Galileo Galilei was a man of many talents and achievements, but there were some things he did not do.
Galileo didn't invent the telescope
Galileo made all his famous observations with the help of a telescope he created. He used spyglasses invented in 1608 — low-powered telescopes capable of magnifying objects three times as a prototype. In 1609, after figuring out how spyglasses worked, the scientist built his own improved version that could magnify a normal vision 8 times. As Galileo kept working on his invention, he made a telescope capable of 20x magnification a few years later. Nowadays, amateur astronomers use telescopes with 20x or 30x magnification for planet viewing. Galileo's telescopes were not flawless, as they had a very narrow field of view, making finding objects more difficult. Nevertheless, it didn't stop Galileo from observing.
Galileo didn't discover the laws of gravity
Galileo Galilei is often credited with discovering the laws of gravity, but this is only partially accurate. While Galileo contributed significantly to understanding gravity and its effects, he did not realize the underlying laws governing the force. The concept of gravity can be traced back to the ancient Greek philosopher Aristotle, who believed that objects fall to the Earth because they are naturally attracted to it. However, the work of Sir Isaac Newton in the 17th century led to the laws of gravitation, which describe the universal force of attraction between all masses.
Galileo didn't prove that the Earth rotates
Galileo Galilei is frequently associated with proving that the Earth rotates, but this is also a misnomer. The idea that the Earth rotates on its axis was first proposed by the ancient Greek philosopher Pythagoras and later developed by Aristarchus in the 3rd century BCE. However, this idea was largely dismissed during the Middle Ages and was not widely accepted until the work of Galileo and other scientists during the Scientific Revolution. Galileo made important observations and experiments that helped support the idea of a rotating Earth, but he did not prove it conclusively. Later, the evidence for a rotating Earth became more solid and widely accepted through the work of other scientists such as Johannes Kepler and Isaac Newton.
Galileo didn't say, "And Yet It Moves"
The phrase "And yet it moves" is often attributed to Galileo Galilei as a symbol of his defiance of the Catholic Church's views on the Earth's place in the universe. However, the exact origin of the phrase is unclear, and there is no direct evidence that Galileo ever said it. It is possible that the quote was first attributed to Galileo by later writers who wanted to highlight his bravery in the face of opposition from the Church and other authorities. Regardless of its origin, the phrase has become a popular representation of Galileo's groundbreaking ideas and discoveries and his impact on the history of science.
Examining Galileo's theories: are there any flaws?
While Galileo's ideas were groundbreaking for his time, they were also limited by the scientific understanding and technology available to him. He made many important contributions to the field of science, but some of his ideas were later found to be incorrect.
The theory of tides
Galileo believed that the tides were caused by the sloshing of ocean water back and forth due to the movement of the Earth. However, it was later shown that the tides are caused by the Moon's and Sun's gravitational pull.
The nature of comets
Galileo believed that comets were atmospheric phenomena rather than celestial objects. However, it was later shown that comets are, in fact, small, icy bodies that originate from the outer reaches of the Solar System.
The idea of a perfect vacuum
Galileo believed creating a perfect vacuum, a space devoid of all matter, was possible. However, it was later shown that a perfect vacuum is impossible due to particles, such as electrons and photons, that exist even in empty space.
Galileo's stargazing traditions continue today
Galileo was passionate about stargazing and encouraged others to observe the night sky and explore the universe. He wrote extensively about his observations and discoveries, sharing his knowledge and enthusiasm for astronomy with others.
It is still possible for amateur stargazers to make astronomical discoveries. With the advancements in technology and accessibility to equipment, hobbyist astronomers can contribute to the field of astronomy in meaningful ways.
One notable example is amateur astronomer, Terry Lovejoy, who has discovered several comets using commercially available equipment.
Another example of a contemporary discoverer is Gennadiy Borisov, who has made significant contributions to astronomy. He discovered the first interstellar comet, 2I/Borisov, originally designated C/2019 Q4 (Borisov), in 2019, demonstrating that comets from other star systems can visit our Solar System. His discovery highlights the role of amateur astronomers in advancing the field despite limited resources.
These examples show that enthusiast stargazers can make meaningful contributions to astronomy, and their passion for stargazing can lead to discoveries.
Galileo’s discoveries: Bottom line:
Galileo Galilei (1564-1642) was the first to observe the mountains and craters on the Moon, the phases of Venus, and the four largest moons of Jupiter. He also studied sunspots and proved that the Milky Way was a collection of stars rather than a huge cosmic cloud. For these and many other achievements, he is often called the “father of observational astronomy”. He made many scientific discoveries outside the field of astronomy as well. Want to be like Galileo?

Even though she had to have both her eyes removed due to Glaucoma last year, no one can guard a dinner better than our June-Bug. There is no way Freddie and Oliver are getting near that bowl.

Patches was an abandoned and I think abused cat. I found him wondering around our property in early 2003. He was declawed, skin and bones, frost bite on his noise and on the bottom of the pads of all 4 of his paws. Now here we are in 2015 he has congenial heart disease and arthritis.
When I found out on Christmas eve 2009 that I had Glaucoma, they took my licence away right away (but I got it back) and then 2 weeks later I found out Patches had congenial heart disease and would only live maybe 2 years if I was lucky, I was much more upset about my cat! My good luck charm! My Patchy! This is why he is the most special cat in the whole house!

Hi my dear friends. I'm very touched by your words, comments and e-mails.
I'm not ok yet. The pain is a little better but I'm with low vision.
New surgery in January: this time is for glaucoma.
Perhaps I'll go to USA next year to see doctors there, but as you know, is very expensive a treatment there but I'll try.
Well, it's Christmas time, so i decided to put this picture I took last november at a mall here in São Paulo.I'll try to visit you during this week.
Lots of kisses and hugs.
Thank you my friends.
I have Ocular Hypertension (High Eye Pressure) and have had for over ten years, I have my eyes monitored at my local hospital and have taken eye drops morning and night for some years now, just to keep a watch for encroaching Glaucoma, where you gradually lose your peripheral vision without realizing what is going on until it's too late......glad to say that although my pressures are persistently high, my vision for now is good, apart for wearing glasses for reading anything or looking at the back of my camera or a computer.......which finally leads me to my posted image......get your bloody eye's checked!
