The Glaucoma Department at The Eye Foundation is well equipped with all latest instruments for the management of various disorders pertaining to eye pressure.
We have state-of-the-art facilities required for the diagnosis and management of glaucoma. We at The Eye Foundation provides the best glaucoma treatment and its related surgeries at an affordable cost
Initial workup includes measurement of intraocular pressure (IOP) with help of Goldmann’s Applanation tonometer. Usually, IOP for normal individuals should be <21 mmHg. Any values more than that warrants further glaucoma evaluation for glaucoma surgery.
Measurement of central corneal thickness is mandatory before starting the patient on medications. It is done using Pachymeter which measures corneal thickness and gives us adjusted intra ocular pressure.
The angle of the anterior or iritis chamber is assessed by gonioscopy lens and if found occludable and left untreated can lead to an angle-closure attack. This is further confirmed by Ultrasound Bio Microscopy (UBM) and if the angles are confirmed to be narrow, the patient is advised Nd: YAG Laser iridotomy in which laser beam is used to open up the blocked passage. It is painless and is done on an outpatient basis.
Visual fields analysis is an integral part of glaucoma management. We have Zeiss Humphrey’s Field analyzer which allows us to interpret visual fields, locates non seeing areas of patient and to assess progression and plan or change medications accordingly.
Stereoscopic photographs of disc for documentation and progression is taken on Heidelberg fundus camera.
Optical Coherence Tomography (OCT) ,the latest advancement, gives us an analysis of optic nerve head and retinal nerve fiber layer, the parts of the eye which is first affected in glaucoma. We have Optovue Spectral Domain OCT which gives high resolution,3 D images of retina and optic nerve to assess the severity of damage and it also measures progression of glaucoma.
Although medical management is the mainstay of glaucoma treatment and medications, some patients with advanced glaucoma, with co-existing cataracts, not controlled by medical therapy, for such patients glaucoma laser surgery is the treatment of choice.
We do Glaucoma surgeries like trabeculectomy with antimetabolites to create alternate pathways for fluid to flow, Gonioscopy assisted Transluminal Trabeculotomy(GATT), the latest technique for early to moderate glaucoma and glaucoma drainage valve implants for refractory glaucoma performed by highly qualified surgeons at our center.

Glaucoma is a common eye condition in which fluid pressure inside the eye rises to a level higher than that is healthy for that eye, thereby causing damage to optic nerve leading to irreversible loss of vision and even blindness.
It could be open angle type which is usually asymptomatic and hence gets diagnosed only in later stages. In closed angle type, the eye pressure rises due to block in outflow pathway.
It is usually asymptomatic, commonly called as” silent theft. ”It depends on type of glaucoma. Open angle glaucoma do not cause any symptoms, some can compliant of haloes and defective side vision. Acute angle closure glaucoma can cause severe headache, eye pain, nausea, vomiting, blurred vision, haloes and redness of eyes.
Anyone can develop glaucoma after 40 years. If there is a strong family history of glaucoma, they are at high risk. Such patients should get it checked annually.
Once Glaucoma is confirmed, your doctor prescribes medications so that you intra ocular pressure is under control. You must be very compliant with medications as glaucoma is mostly managed by medications. Laser is done for closed angles. Surgical treatment is for those with advanced glaucoma and in those not controlled by medications and in congenital glaucoma.
No. It is a simple outpatient procedure, requires no injections. It uses laser to create a passage for fluid to egress so that your eye pressure is under control.
During your visit, you will first be taken through a routine checkup of your refraction by a qualified team of optometrist. A routine glaucoma work up includes measurement of intra ocular pressure, corneal thickness and angle evaluation. If your angles are narrow, you would require a prophylactic YAG peripheral iridotomy, which is done on same day. If there is any suspicion of glaucoma by looking at your optic nerve, you might be asked to do further tests like visual fields and OCT. Following dilatation, it might be difficult to drive for several hours.
Some medications can cause dry eyes. Beta blockers are contra indicated in cardiac patients and asthmatics. Most of the medications are to be avoided in pregnancy and lactation unless benefits exceed the risk.
