Glaucoma is a potentially blinding disease (commonly known as Kala Motiya or sabalbai) and the vision and field losses caused by this are irreversible. The department is equipped with the state of the art HUMPHREY Field Analyzer, Perkins Tonometer and standard Applanation Tonometer, UBM and OCT for optic disc and retinal nerve fibre layer analysis. Glaucoma screening tests and gonioscopy, diurnal variation for Glaucoma suspects are routinely carried out.
HUMPHREY Field Analyzer
Ultrasound biomicroscopy utilizes high frequency transducers to obtain high resolution. Our unit, with a 50 MHz transducer, achieves a resolution of approximately 50 microns, and has a tissue penetration of 4-5 mm. Scanning is performed with the patient in the supine position under standardized room lighting conditions. Scanning is performed under topical anesthesia using a 20 mm eye cup which is inserted between the lids and filled with saline solution. In vivo, cross-sectional or transverse images can then be obtained detailing the cornea, iris, ciliary body, anterior chamber angle, and peripheral sclera to demonstrate structural relationships.
Glaucoma surgery being done in the department is at par with that being done elsewhere.
