Aim: The purpose of this study was to evaluate AC angles using gonioscopy, Van Herick technique and AS-OCT, focusing on their potential role in clinical practice. Methods: The Cross-sectional study was conducted and patients of more than 40 years of age attending ophthalmology outpatient department at Govt. Medical College, Patiala. 100 patients were included in the study. Data was collected from the patients more than 40 years of age willing to participate in the study. Patient data was collected according to the Performa. Medical history and history of any ocular disease was also noted. Results: 40% of the patients belonged to 60-70 years age group, followed by 50-60 years (37%), 40-50 years (12%), 70-80 years (10%), and >80 years (1%). Majority of the patients belonged to 50-70 years (77%). 56% were females and 44% were males. 53% patients had VH grading (nasal) 3 followed by grade 4 (26%), grade 2 (10%), grade 1 (8.5%), and grade 0 (2.5%). 52% patients had VH grading (Temporal) 3 followed by grade 4 (26%), grade 2 (10%), grade 1 (9.5%), and grade 0 (2.5%). The agreement value between the nasal and temporal VH grading was found to be 98%. Conclusion: The van Herick method appears to have good sensitivity and specificity, whereas the AS-OCT method has poor sensitivity, yet high specificity. The Van Herick method, because of its high sensitivity and high negative predictive value can be used as a screening tool in detecting angle closure. ASOCT on the other hand, having a high specificity can be used to confirm angle closure and detect the mechanism of closure to some extent.
