Abstract :
Background: PACS (primary angle closure suspects) continue to pose a diagnostic and therapeutic dilemma. PACS being converted to PACG as the disease evolves in the long run leads to irreversible blindness; hence the importance of screening with gonioscope to see which patients will improve with laser peripheral iridotomy (LPI).
Objective: To assess the effectiveness of routine manipulative gonioscopy as a tool in order to predict angle opening after Nd-YAG laser iridotomy in PACS patients.
Methods: Fifty patients having PACS were enrolled in the prospective observational interventional study. Main outcome measure were effect on IOP, effectiveness of manipulative gonioscopy with regard to angle opening and Van Hericksin predicting angle changes. Manipulative gonioscopy and Peripheral laser iridotomy was done. Wilcoxon signed rank was used to find the significance of study parameters.
Results: Seventy four percent were females with males forming 26% of the study. Mean age was 65 ± 5.16 years. Comparison of Shaffers grading pre and post intervention in superior quadrant showed P value 0.020(suggestive of significance), inferior quadrant showed p
