Introduction: At present 12 million Indians were affected by glaucoma accounting for 12.8% of the blindness of the country with 45 to 55% of primary glaucoma being PACG. The screening of patients with a high risk of iridotrabecular contact and subsequently primary angle closure is important. Early diagnosis and treatment is very much essential in dealing with high risk groups for angle closure glaucoma having occludable angle. The main aim of this study is to screen for Angle Closure Glaucoma in high risk groups with the Objectives:1) To know the incidence of occludable angles in high risk groups for angle closure glaucoma. 2) To highlight the importance of screening for angle closure suspects in high risk groups. Methodology: The present longitudinal study was conducted in the Dept. of ophthalmology, Dr Pinnamaneni Siddhartha Institute of Medical Sciences and Research Foundation (Dr.PSIMS), Chinoutapalli, Krishna District, Andhra Pradesh with the institutional ethical committee clearance. A sample of 100 selected patients who attended ophthalmology opd as outpatients. Results: Out of 100 cases 18% patients had occludable angles, 72% patients had open angles.Degree of hypermetropia in the occludable angles: Out of 18 cases with occludable angles 4 eyes had hyperopic error between 0.50-1.00D, 9 cases had hyperopic error between 1.25-2.00D,5 cases had hyperopic error between 2.50-3.00D. In the present study, 20% cases were known Diabetics out of them 40% had occludable angles. Conclusion: Measurement of peripheral anterior chamber depth is believed to be useful for glaucoma screening and gonioscopy should make the final assessment. For primary angle closure (PAC) or early primary angle closure glaucoma, case detection presents the unique opportunity to prevent blindness from glaucoma.
