Glaucoma is a disease that damages the optic nerve. The optic nerve carries electrical impulses of the light images transformed by the retina, to our brain. Damage to the optic nerve and retina causes blind spots in the field of vision. In extreme cases, if the entire nerve is destroyed, blindness will occur.

Glaucoma is in fact one of the leading causes of blindness and affects an estimated one of every 50 adults. Although glaucoma can occur at any age, the risk of developing this increases dramatically after the age of 35. Globally, people who are more likely to develop glaucoma if they are severely near-sighted, have a family history of the condition, or diabetic or African American. The disease often goes unnoticed because the early symptoms of glaucoma are so slight, and by then the damage done is permanent. However, at Banaji Eyecare, with early detection and careful treatment, loss of vision due to glaucoma can be prevented.

Screening For Glaucoma

At Banaji Eyecare, we use the latest in modern technology to detect glaucoma at the earliest, so you don’t have to worry about losing your vision.


Screening with Ocular Coherence Tomography (OCT) enables diagnoses of potentially serious conditions that can affect your eyesight. An advanced eye scan, OCT, uses light to illustrate the different layers that make up the back of your eye. In OCT scan, a digital photograph and a three dimensional cross sectional scan of the back of the eye are obtained.

At Banaji Eyecare the OCT scan is used extensively in detecting if you are at risk of glaucoma or the stage of glaucoma you are at. We use SPECTRALIS® SD-OCT, which acquires 40,000 A-scans per second. The increased speed and number of scans translates into higher resolution and a better chance of observing disease.

OCT is also used to detect, identify and monitor the progress of age-related macular degeneration and macular hole. It also enables the early detection and treatment of diabetic retinopathy and vitreomacular traction.


The Frequency Doubling Technology (FDT) perimeter is an instrument designed for fast and effective detection of visual field loss. It is particularly useful and has displayed high sensitivity and specificity to early glaucomatous defects.
