To determine the efficacy of 5-Fluorouracil (FU) in the treatment of pterygium. Methodology After meeting the inclusion criteria 101 patients were enrolled in this study. Informed consent and demographic information was taken from all the patients. Patients underwent ophthalmic clinical examination that included slit lamp examination to grade pterygium. Before starting 5-FU injections, all topical medication was stopped. After four weeks the effects of 5-FU and its efficacy was noted. The patients were reviewed again after six months to note any recurrence. All the collected data was entered and analyzed on Statistical Package for Social Sciences (SPSS) version 20 (IBM Corp., Armonk, NY). Results In our study the mean age of the patients was 37.74 ± 10.15 years, male to female ratio of the patients was 1.06:1. The primary type of pterygium was noted in 54 (53.5%) and recurrent was noted in 47 (46.5%) patients. The efficacy achieved in 88 (87.13%) patients, four had recurrence of pterygium and of 101 patients 26 underwent surgical excision. Conclusion The use of 5-FU is safe and effective for the treatment of pterygium and it can be implemented as a primary treatment especially in the hot temperate zone where it is very common and aggressive with high recurrence rate. 5-FU not only halts its progression but also reduces the size and vascularity thus decreasing the need for surgery and steroid use and preventing recurrence.
Introduction: A randomized control trial To compare efficacy of oral rifampicin in terms of drying of macula and decrease macular thickness with observation alone in patients of acute central serous Chorioretinopathy done in Layton Rahmatulla Benevolent Trust (LRBT) Free Eye and Cancer Hospital, Lahore from January 2017 to June 2017 Methods: After getting approval from hospital Ethical committee 140 patients of CSR were included in the study. The demographic details were noted and patients were randomized by lottery methods in two groups (group A& B). Group-A was observed for spontaneous resolution, routine treatment started if no improvement noted after 6 weeks of observation alone. Group B was given oral rifampicin 600mg per day for four weeks with liver function tests being done before commencement of treatment and after 2 weeks. Oral rifampicin was stopped if patient developed deranged liver function tests. Patients were followed up at 4 weeks for macular dryness and decrease macular thickness on optical coherence tomography(OCT). All the readings were carried out and noted by single person in order to minimize bias. Results: A total of 140 patents, 70 in each group, were included In study with mean age 38.77+7.74 in Group-A and 39.14+7.97 years in Group-B. regarding gender distribution 65.71 %(n=46) in Group-A and 613.43%(n=43) in Group-B were male. Comparison of outcome of treatment of acute central serous chorioretinopathy with oral rifampicin vs observation showed that 18.57 %(n=13) in Group-A and 41.43%(n=29) in Group-B had dry macula. Conclusion: We concluded that there is a significant difference in drying of macula in acute central serous chorioretinopathy with Rifampicin versus observation alone.
Background: To determine the frequency of Ocular toxicity due to Ethambutol in Category-1 patients after receiving DOTS therapy. Methods: Category-1 tuberculosis patients of 15-60 years (both gender) with normal ocular parameters on ophthalmological assessment at time of initiation of DOTS therapy were included in the study. A total of 242 eyes (121 patients) were studied for any change in the vision or occurrence of any other ocular symptom while on the Ethambutol treatment. Each patient was followed up for Ethambutol compliance status at the completion of one month and again at two months of treatment, all the ophthalmological assessments for ocular toxicity were repeated for every selected patient. Category-2 patients with sputum smear positive who have relapsed, who have treatment failure or who are receiving treatment after treatment interruption were excluded from the study. The patient’s information was gathered on a specifically designed proforma. The information on the proforma was filled by the researchers themselves. Results: Out of 121 patients (242 eyes), 64 (52.9%) were males and 57 (47.1%) were females. There was no sign of ocular toxicity after a month period. However, after second month ocular toxicity was developed in 02 (1.65%) of the patients. Besides, decrease in visual acuity, color vision abnormalities, decrease in contrast sensitivity, and optic disc abnormalities were also observed in these 02 patients. Conclusion: There is a possibility of the occurrence of ocular toxicity when the Ethambutol is taken by the tuberculosis patients. Thus, the early identification of ocular symptoms and signs is vital to avoid unnecessary delay in diagnosis and probable irreversible visual loss.
