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. [ABSTRACT FROM AUTHOR]

Background: Objective of this study was to compare Reverse Tenzel flap and Cutler Beard flap for upper eyelid defects. Methods: This interventional study was carried out at occuloplasty department of LRBT (Layton Rahamatullah Benevoloent Trust), Karachi. Patients diagnosed with upper eye lid defect between 50 and 75 years were included after ethical approval from institutional ethical review committee and briefing patients about study dynamics. The patients were randomly divided in two groups, group A in whom reverse tanzel flap was done, while in group B Cutler beard procedure was done. Main outcome measure was eyelid contour, complete lid closure and surgical procedure time. SPSS version 25.0 was used for data analysis. Results: Reverse Tenzel flap mean age 64.00±6.17 years, mean duration of surgery 33±5.78 minutes, and mean healing time 2.2±0.41 weeks. Cutler Beard flap mean age 59.60±6.26 years, mean duration of surgery 32±5.78 minutes, and mean healing time 5.7±0.8 in 3 weeks. 60% of patients were female. 30 (50%) patients each underwent Reverse Tenzel flap and Cutler Beard flap. In Reverse Tenzel flap, no complications were observed. In Cutler Beard flap, 06 (20%) patients reported mild entropion, 04 (13.3%) retraction of flap and 02 (6.7%) were found to have mild incomplete lid closure. Conclusion: Reverse Tenzel flap was superior to Cutler Beard flap as it reported no complications, being single stage surgery with early healing. Cutler-Beard flap reported mild entropion and retraction of flaps which required second surgery and delayed healing. [ABSTRACT FROM AUTHOR]

Background: The surgery of macular hole is a complex and intricate micro-surgery and chances of recurrence of macular hole are always high. Therefore, in order to provide a medium to close this hole, we carried out this research on subjects using amniotic membrane, in light of the studies being conducted around the world. This in turn led to benefitting the patients by improving their vision over time. Purpose: To assess the rate of recurrent macular hole closure with amniotic membrane plug. It was a Quasi-experimental study, conducted at Layton Rahmatullah Benevolent Trust (LRBT) Free Eye Hospital Karachi, from January 2019 to January 2020. Methods: This study was conducted using 13 eyes of 13 patients with recurrent macular hole who underwent amniotic membrane plugging via pars plana approach. Outcomes measured were changes in best corrected visual acuity (BCVA) and change in hole size with the help of optical coherence tomography (OCT). Results: Anatomic closure was attained in 100% of the cases whereas BCVA improved from 1.7±0.33 (6/300) to 0.9±0.15 (6/48). Conclusion: The use of AM is a functional method for management of large RMH. [ABSTRACT FROM AUTHOR]

Fifteen benzophenone thiosemicarbazones were synthesized and their in vitro antiglycation activity was evaluated. The most active compound 2 (IC50 = 118.15±2.41µM) showed two folds potent activity than the standard, rutin (IC50 = 294.5±1.5µM). Compounds 1 and 3-7 showed good to moderate antiglycation activity in the range of 204.14 - 488.54µM. These compounds were also evaluated for antioxidant activity. Their structure-activity relationships have been developed. The results reveal the potential of these compounds as leads for further studies towards the development of antidiabetic drugs.

A series of synthetic 2-aryl-4(3H)-quinazolinones (1-25) was evaluated for in vitro antileishmanial activities against promastigotes of Leishmania major. Compound 1, with nitro group installed at C-4', was found to be the most active analog having the IC50 value of 35.8 ± 0.1 µM against the standard, pentamidine (IC50 = 5.09 ± 0.09 µM). Fourteen other derivatives i.e. 2, 5-8, 10- 12, 14, 16, 19, 22, 24, ad 25, showed a moderate to weak antilieshmanial activity with IC50 values between 62.8 - 90.45 µM. The results indicate the potential of these compounds as leads for further studies towards the development of antileishmanial drugs. [ABSTRACT FROM AUTHOR]
