Recent advancements in surgical training methods have escalated the need for simulators. The EyeSi simulation has played a major role in Ophthalmology training by providing opportunity to the novice residents to grasp the surgical steps of the procedure and master the skill by repeated attempts. Participants were assessed on single level of cataract module and their consecutive scores were assessed with each attempt. It was found that repetitive practice on simulator can help develop proficiency in the desired steps that can ultimately prepare the surgical trainees for real life surgery.

Spontaneous Closure Of Full Thickness Macular Hole In The Presence Of An Epiretinal Membrane In A Vitrectomised Eye: A Case Report, Rehman Siddiqui, Muhammad Umar Fawad, Nida Ahsan
Section of Ophthalmology
We report the case of a spontaneous closure of full thickness macular hole (FTMH) in the presence of an epiretinal membrane (ERM) in a previously vitrectomised eye. The patient had undergone vitrectomy for rhegmatogenous retinal detachment and developed an ERM two weeks after the surgery, which converted into a FTMH after one week. Eight months after the vitrectomy, spontaneous closure of FTMH was observed with an improvement in best-corrected visual acuity (BCVA) from 20/200 to 20/40. The patient was followed up for four years, and the FTMH remained closed. Spontaneous closure of FTMH is possible even in the presence of …

Section of Ophthalmology
A 25-year-old male presented with a complaint of acute visual loss in his right eye for two days. There was a history of visual loss in the left eye six months ago. Comprehensive eye examination showed evidence of posterior uveitis, and a placoid lesion on the right fundus. Further physical examination showed maculopapular rashes on the upper back which was highly suggestive of syphilis. Blood tests for venereal disease research laboratory (VDRL) test and fluorescent treponemal antibody absorption (FTA-ABS) test were ordered, which were both positive. Ocular syphilis should be suspected in all cases of uveitis. Early diagnosis and prompt …

Otosclerosis: Experience With Stapes Surgery, Muhammad Shaheryar Ahmed Rajput, Asif Ali Arain, Arsalan A. Rajput, Mohammad Adeel, Anwar Suhail, Mohammad Sohail Awan
Section of Ophthalmology
Introduction: Otosclerosis is a disorder in which the footplate of the stapes is replaced by an abnormal bone, thereby affecting sound transmission to the inner ear at the level of the oval window. The solution to this condition is to reestablish this mechanism back to normal via the ossicular chain to the inner ear. The aim of stapes surgery is to improve the hearing level to thresholds appropriate enough to obviate the need for hearing aid. The hearing improvement achieved after surgery often lasts for many years. The purpose of the current study was to review our experience and find …
