Purpose : A retrospective study from glaucoma clinic of a tertiary eye care hospital from India over a 16-month period. The study aimed at evaluating the sub-types of glaucoma, stage of disease and treatment protocol at the centre
Methods : All subjects underwent a detailed ophthalmic examination in our glaucoma clinic as per the routine protocol including applanation tonometry, gonioscopy, ultrasound pachymetry, perimetry/pre-perimetric test and any other relevant investigation. Glaucoma was defined using modified International Society of Geographical and Epidemiological Ophthalmology criteria
Results : Of the 1058 patients, males predominated at 60%. Majority of them (54%) were in the 6th decade or above, while 38% were between 20-50 years of age and 8% younger than 20 years.
Glaucoma subtypes were: angle closure glaucoma (PACG) 23%, ACG suspects 13%, open angle glaucoma (POAG) 22%, POAG suspects 15 %, secondary glaucoma 13% and primary congenital glaucoma (PCG) 2.5%. No glaucoma was seen in 11.5%.
Almost 13% presented with glaucoma blindness in one eye. Glaucoma surgery was required in 17.5% while 32% could be controlled on anti-glaucoma medications
Conclusion : Primary glaucoma predominates in hospital referrals, equally distributed between closed and open angle subtypes. Advanced glaucoma was fairly common, with almost 1/4th cases requiring surgical intervention. Referral practice was robust with over-diagnosis occurring in mere 12%.
