Glaucoma

Overview

Glaucoma is a disease of the optic nerve and leading cause of permanent blindness worldwide. Although glaucoma is neither preventable nor curable, the progression of the disease can be halted with appropriate treatment. Once nerve fibers die and visual function is lost, it cannot be recovered. Treatment can only help preserve remaining vision; hence it is imperative to detect the disease in its earliest stage. Often, glaucoma is asymptomatic. Therefore, people suffering from glaucoma may lose vision without knowing it. Regular eye exams are an important way to detect glaucoma. There are several types of glaucoma, and treatment depends on properly identifying which kind is present. One factor common to all forms of glaucoma is damage to the optic nerve. All types of glaucoma need some form of treatment. Treatment depends on the type and severity of glaucoma and it may be in the form of medication, laser therapy or surgery.


Glaucoma Dept. of IIEIH is the largest national referral centre for secondary and tertiary management of glaucoma. It manages over 25,000 glaucoma attendances annually. Our glaucoma consultants manage both paediatric and adult glaucomas with around 1000 glaucoma surgeries performed every year.


The Glaucoma Dept. is also involved in teaching at multiple levels. Residents who are specializing in ophthalmology rotate through the Glaucoma Dept. We also run the only fellowship programme within the country. The fellow is with us for 15 months. Fellows are ophthalmologists who have chosen to spend an extra 15 months subspecializing in glaucoma.

Services


Glaucoma cannot be cured, but it can be successfully controlled in most cases. Here at Glaucoma Dept.,IIEIH we provide care for infants and children, adults, and all types of glaucoma patients, whether primary or related to complex eye problems. Medical treatment, laser therapies, and surgical procedures for glaucoma are available.


Our Glaucoma Dept. manages the following glaucoma conditions:


◊ Paediatric Glaucoma
◊ Primary Open Angle Glaucomas including Normal Tension Glaucoma
◊ Primary Angle Closure Disease
◊ Secondary Glaucomas

LASER SERVICES

We perform more than 1,000 laser procedures in the management of glaucoma annually and these include:


♦ Laser Peripheral Iridotomy
♦ Laser Iridoplasty
♦ Laser Suture Lysis post-trabeculectomy

SURGICAL PROCEDURES

Various glaucoma surgeries for both paediatric and adult patients are performed which include:


♦ Trabeculectomy with anti-metabolites and collagen matrix implant
♦ Trabeculotomy with and without trabeculectomy
♦ Combined Trabeculectomy (with anti-metabolites) and Cataract surgery
♦ Bleb Needling with anti-metabolites
♦ Bleb Revisions

Facilities


Our Glaucoma imaging service utilises sophisticated, state-of-the-art diagnostic facilities for early detection and monitoring of glaucoma. These include:


Optic Disc Photography: Clinical documentation of glaucomatous optic disc damage and monitoring of glaucomatous
progression

Optical Coherence Tomography (OCT): Optic Nerve Head and Retinal Nerve Fibre Layer Imaging Technology for structural evaluation of the optic disc to document glaucomatous nerve damage and monitor progression

♦ Combined Trabeculectomy (with anti-metabolites) and Cataract surgery

Automated Visual Field Analysis (Humphrey Visual Field Analyzer and Octopus Visual Field Analyzer): Functional evaluation of glaucoma-induced visual field defects
