Clinical Outcome After Nd: Yag Laser Iridotomy In Patients With Primary Angle Closure Glaucoma: A Hospital Based Study

Purpose: To find out the clinical outcome of Nd: YAG Laser iridotomy in primary angle closure glaucoma (PACG) Study Design: Experimental case series Place and Duration of Study: Prevention of Blindness Eye Hospital Karachi, from January 2021 to June 2021. Methods: Patients of 30 to 60 years of age, either gender and diagnosed with primary angle closure glaucoma were included. After taking informed consent, complete examination including pre and post laser intra ocular pressures (IOP) was performed. Follow up was at 2 hours, 1 day and 1week. Data was collected and analyzed using SPSS version 22. Effect modifiers like age, gender, pre-laser lOP were controlled through stratification. Post stratification Chi square test was applied for complications (raised IOP, iritis, hyphema, corneal damage, lens opacity and posterior synechie) and efficacy. P ? 0.05 was considered significant. Results: Mean age of the patients was 44.48±7.28. Stratification of age and gender with efficacy of LPI and early complications showed that there was no effect of age and gender on the results of LPI (p>0.05). Mean pre laser IOP was 18.56±5.28 and post laser IOP was 15.28±4.62. Lens opacity was found in 10 (5.15%), followed by hyphema in 9(4.63%), corneal damage 8 (4.12%), posterior synechie 5 (2.57%), iritis 7(3.60%), raised IOP in 6 (3.069%) patients. Conclusion: It is to be concluded that Laser iridotomy is an effective treatment for PACG even in thicker and more heavily pigmented irides with few reversible side effects.
