laucoma is commonly known as the ‘sneak thief of sight’ because it can cause irreversible vision loss without any obvious symptoms. Up to 50% of all people with glaucoma are not even aware they have the condition. However, if it is diagnosed early, treatment can begin and vision loss can be prevented.
The term glaucoma actually refers to a group of conditions that lead to eye (optic) nerve damage. This nerve transmits signals from the eye to the brain to produce the image that we see. When a significant number of nerve fibres are damaged, your side (peripheral) field of vision is lost – this vision loss gradually extends towards your central vision, until eventually all sight is lost. Vision loss caused by glaucoma is permanent.
Damage to Eye
Most cases of glaucoma are due to an increased pressure inside the eye (intraocular pressure), either from the drainage angle being closed (angle-closure glaucoma) or the drainage angle being open but damaged (open-angle glaucoma). A specific part of the eye called the trabecular meshwork provides natural resistance to the drainage of fluid from the eye. It is a failure of this meshwork that often causes raised eye pressure and, in turn, glaucoma nerve damage.
Glaucoma nerve damage can also occur with normal eye pressure. This is known as normal-tension glaucoma and is thought to be related to poor blood supply to the eye nerve.
If your GP or optometrist suspects that you have glaucoma, you will be referred to an ophthalmologist for further investigation. A number of tests will be carried out to confirm the diagnosis, including:
- Visual acuity (clarity) test using an eye chart
- Visual field test to determine peripheral vision
- An examination that involves using drops to dilate the pupils of the eye
- Tonometry to measure eye pressure
- Pachymetry to measure corneal thickness
- Gonioscopy to see if there is a blockage where the fluid normally drains out of the eye, and to distinguish between open-angle and closed-angle glaucoma
- Optical coherence tomography (OCT) to scan the optic nerve head to aid diagnosis and monitoring
Hi, Recently I had cataract surgery(Multi focal IOL implementation) in Smart Vision. Before I visited this Smart Vision, I have visited Biggest eye hospitals in Hyderabad and scared about surgery. But in Smart Vision Doctor guided me perfectly. He has answered my questions very patiently. Finally I have admitted for cataract surgery in Smart Vision. Surgery is very painless. Doctor and his staff member treated me as their family member. Now I am able to enjoy quality of Life without glasses with clear vision. Cost is also reasonable here, there is no fraud like other hospitals because this is one of the biggest Eye Hospital in India which is established by doctors association. I am recommending this hospital with high priority for any kind of eye problems. Thanks a lot Doctors and smart vision Team.
Their service is above all stars. Clinic is no doubt the best in its kind. Stands out from the rest in standards, hospitality, cleanliness, affordability and especially Doctor is the best. He is very patient and treats the problem with ease and empathy. He never hurries and explains every possible detail with patience. He was never hesitant in emergency times as well. Happy I got my PRK in his clinic , I would recommend this 100%.
My 2 year old was seen at Smartvision Eye Hospitals by Doctor. We found out she has squint and feel like we are in great hands. He really made sure that the procedure would be safe and not to worry. Me being an over protective parent I have bugged him with lots of questions and on the day of surgery I was really scared about giving GA to my kid and surgery. But the staff was very kind and assured me that am in safe hands. Post surgery my kid had little discomfort for the first two days. But later on she is happy. Thank you team.
I have got glasses and wanted to get rid of them. When I have approached Doctor, He has explained me all the options i could opt for and I went ahead and got the surgery done. First day was little painful and I started feeling better from the next day. Three days post surgery am perfectly fine. It was really simple. Thank you smart vision.
The kindness, care, and professionalism given by the entire staff and the surgeon changed what I thought would be a terrifying experience to a calm and positive experience with an amazing out come. The clarity and brilliance of colors with my improved eyesight. Thank you, SmartVision!
Patients with glaucoma require ongoing care by an ophthalmologist.
Unfortunately, there is no cure for glaucoma. But there are a number of treatment options available to help reduce eye pressure and minimise or prevent further vision loss. Sometimes a combination of treatments may be used.
Starting treatment as early as possible is critical for preserving as much of your remaining eyesight as possible, but vision that has already been lost cannot be recovered. Make sure you have regular eye checks with an optometrist, even if you don’t require glasses to see, as they will routinely check your eye pressure. This is particularly important for people who are at high risk of developing glaucoma.
