Objective: To compare the reliability of Bruch Membrane Opening-Minimum Rim Width (BMO-MRW) Optical Coherence Tomography (OCT) with Retinal Nerve Fibre Layer (RNFL) in myopic patients.
Purpose: To assess the difference in intraocular pressure before and after Nd-YAG laser posterior capsulotomy. Study Design: Quasi-experimental study. Place and Duration of Study: Layton Rahmatulla Benevolent Trust Eye Hospital, Karachi, from July 2021 to October 2021. Methods: Patients of both gender with posterior capsular opacification (PCO) after cataract surgery, were included. Age ranged between 40 and 60 years. Patients with less than 6 months of surgery were excluded. Patients with posterior segment pathology like glaucoma, uveitis, high myopia, diabetic retinopathy, macular pathology, and hereditary fundus dystrophies were excluded from the study. After detailed history, complete ocular examination was performed. After pupil dilatation, YAG laser capsulotomy was done.IOP was measured with Goldmann Applanation Tonometer after instilling a topical anesthetic agent. Post-YAG, IOP was again measured at 1 hour and on day 1. Data was analyzed using SPSS version 25. Paired T-tests were used to assess the significance of any change in IOP. Results: Ninety eyes of 90 patients were inducted into the study in which 51 (57%) were male and 39 (43%) were female. The age varied from 40 to 60 years (mean 52.3 ± 10.25 years). There was no statistically significant difference between pre-YAG and post-YAG IOP. Similarly, no difference in IOP was found depending upon the age of the patients. No significant change was observed after 1 hour and 1 day in both groups with P > 0.05. Conclusion: This showed no significant change in intraocular pressure at one hour and one day, after Nd-YAG laser posterior capsulotomy.
Purpose: To find out correlation between visual acuity and deep capillary plexus (DCP) in foveal avascular zone (FAZ) area using OCTA in patients with retinal vein occlusion (RVO). Study Design: Descriptive observational study. Place and Duration of Study: Layton Rehmatullah Benevolent trust free Eye Hospital, from September 2018 to December 2019. Methods: This observational study included 50 eyes of 50 patients, who were treated with intra-vitreal anti-VEGF for macular edema secondary to retinal vein occlusion. We excluded patients with macular edema due to other ocular diseases. OCTA was performed in every patient to measure the size of foveal avascular zone. FAZ area of 0.6mm2 or less was taken as normal and any value above that was considered to be larger FAZ. IBM SPSS version 25 was used to analyze the data. Frequencies with percentages were used to present qualitative variables and mean ± SD were calculated for the quantitative variables. P-value ≤ 0.005 was taken as significant. Results: Mean age was 58.38 ± 7.51 years. There were 28 males and 22 females. Mean best-corrected visual acuity was 0.62 ± 0.26 logMar. The patients with normal FAZ area in DCP showed a mean BCVA of 0.51 ± 0.265 logMAR in comparison to those who had larger FAZ in DCP, where the mean BCVA was 0.75 ± 0.204 logMAR. DCP was larger in patients with CRVO than BRVO. Conclusion: OCTA is a good diagnostic tool for qualitative and quantitative evaluation of the deep capillary plexus. Improvement in visual acuity is related with the size of the DCP in FAZ. Key Words: Retinal vein occlusion, Foveal avascular zone, Optical Coherence Tomograghy Angiography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
