Glaucoma (KALA MOTIA) is a group of disorders wherein the fluid pressure inside the eye rises to such a level that it damages the delicate structures of the eye specially the nerve of sight (Optic Nerve). It is now understood to be a condition with compromised blood perfusion to the eye and it’s nerve wherein eye pressure is an important but not the only variable.This condition is very different from Cataract (Safed Motia) in which the natural lens of the eye becomes opaque and has to be removed.
Glaucoma is more dreaded than cataract because the loss of vision due to it can not be reversed as opposed to the vision loss in cataract which is easily restored by surgery. Cataract and Glaucoma can also occur simultaneously in the same eye.
Misty morning a lovely sight, but foggy vision a dreadful fright.
Progressive vision loss, visual field constriction in glaucoma.
The Eye does not see what the Mind does not know. Our doctors are specially trained in the best institutions and coupled with vast experience in our hospital they diagnose glaucoma earlier & treat it earlier to save you from later problems.
Early Diagnosis of Glaucoma, Advanced Testing For Glaucoma, Early Start Of Treatment, Regular Monitoring, Proper Counseling, Individual Target Pressure calculations and Experienced Glaucoma Surgeons are all for the long term benefit for Glaucoma Patients
This sequence forms the logic or basis of the various tests for a glaucoma patient as given below.
To measure the fluid pressure inside the eye by various types of tonometers like Schiotz (metallic scale type), Goldmann Applanation (prism with blue light) or the Computerized Non Contact NCT type which measure pressure with a gentle puff of air without actually touching the eye.
To check for the Cupping or Atrophy (damage) of the Optic Nerve due to the drying up of the nerve of sight it suffers damage due to high pressure inside the eye.
As explained earlier optic nerve damage (Optic Atrophy) and consequent blindness due to glaucoma is irreversible, hence early detection with prompt and regular treatment are the keys to successful glaucoma management.
Glaucoma is said to be controlled not cured as treatment can at most halt further damage but generally cannot reverse damage already done.
The aim of treatment is to reduce and to maintain the fluid pressure (I.O.P.) inside the eye at a level at which further optic nerve damage does not occur. The generally accepted upper limit of I.O.P. is 20 mmHg. but levels below this are desirable though there may considerable individual variations.
TARGET I.O.P. for each patient is decided after detailed tests at our hospital. On long term follow up of an individual patient the eye surgeon can be sure of good glaucoma control when I.O.P. remains at an acceptable level at all times and further visual field loss on repeated perimetry (function test) and OCT-RNFL (retinal nerve fiber layer - structure test) does not occur.
In angle-closure Glaucoma, an opening is made in the iris (YAG Laser Iridotomy, LI) to restore the free flow of aqueous fluid and is the initial treatment of choice in these cases.
Various types of Glaucoma Filtering Surgery (trabeculectomy, trabeculotomy, goniotomy, deep sclerectomy, viscocanalostomy etc.)done . Surgery is done generally to create a filtering or fluid drainage channel to control the IOP in Glaucoma. We use miniature instruments to create a new drainage channel for fluid to leave the eye. If needed special adjuvants like 5FU or MMC are used or special Glaucoma shunts / implants / valves / setons may be used. Usually surgery for glaucoma recommended only if the medicines fail to prevent damage or some specific reason.
Since most of the damage due to glaucoma is not reversible, timely and regular treatment and follow-up is very important.
Early detection is the key to preventing progressive loss of sight from glaucoma. A target I.O.P. for a particular patient is determined as per the consultant's assessment.
Our hospital is best equipped for all advanced Glaucoma Tests, Lasers & Surgeries.
