ABSTRACT
Objective: To study the outcomes of passive removal of silicone oil by 23 Gauge Transconjunctival Sutureless Vitrectomy System
Methods: This prospective, consecutive case series study was conducted at Ophthalmology Department Unit I, Dow University of Health Sciences, Civil Hospital Karachi from January 2011 to December 2014. Only psuedophakic eyes with silicone oil temponade were selected. Main outcome measures were intra ocular pressure, time taken for removal of silicone oil, per operative and post operative complications. Pre and post operative IOP was compared by using two-tailed paired t-test and mean values with standard deviation were computed using difference of 95% confidence interval. Chi square test was applied for correlation of different variables. P-value of less than 0.05 was considered statistically significant
Results: Out of 79 patients who underwent passive ROSO, 38 [48.1%] were males. Mean age of patients was 47.5 +/- 7.1 [sd] years. Mean time taken for passive ROSO was 7.31 +/- 2.41 [sd] minutes. Pre and post operative intra ocular pressure shows statistically significant [p=0.000] decrease in IOP. Retinal redetachment found in 13 [16.5%] cases during follow up period
Conclusion: Passive removal of silicone oil with 23 G suture less vitrectomy system is safe and effective in terms of less per operative and post operative complications. In this simple technique, there is less tissue trauma and little time consumed so it provides more comfort to patients and surgeons as well
ABSTRACT
Objective: To find out outcomes of pterygium excision with sutureless, glue free conjunctival auto graft
Study Design: Observational / descriptive study
Place and Duration of Study: This study was conducted at the Ophthalmology Department Unit-I, Dow University of Health Sciences, Civil Hospital Karachi from June 2011 to May 2015
Materials and Methods: Either gender patients above 25 years of age enrolled for primary pterygium excisionfollowed by limbal to limbal orientation of conjunctival auto graft without suture or adhesive glue. Recurrent pterygia, pseudo pterygia, ocular surface disorders, vascularized cornea, dry eye and patients already on topical anti metabolites were not included. Follow up was scheduled on 1[st] day, 1[st] week, 1[st], 3[rd], and finally 6[th] months. Chi square test was applied to check significance of recurrence with age, gender, occupation and graft size or graft application time
Results: Out of 382 participants, 303 [79.3%] were males. Majority of patients [77.7%] were young between 25 to 45 years of age. Mean time required for graft application was 16.89 +/- 2.58 [std] minutes. Recurrence of pterygium was found in 32 [8.4%] cases. No significant relationship of recurrence of pterygium was found with other variables like gender, age, occupation, graft size or graft application time
Conclusion: Natural healing tendency of vascularized conjunctiva allow graft to adhere underlying scleral bed while well aligned autograft margins and limbal to limbal orientation do not allow overgrowth of fibrovascular conjunctival tissue thereby prevent recurrence of pterygium
ABSTRACT
To compare the effectiveness of topical and retobulbar anesthesia in term of pain relief in patients subjected to cataract surgery. This comparative study was conducted at Department of Ophthalmology, Bahawal Victoria Hospital Bahawalpur from 18th July, 2012 to 18th January, 2013. Total 100 patients with cataract were included in this study. Mean age of the patient was 64.14 +/- 8.7 years. No. of patients in RA group who reported the pain scores [0- 4] during cataract surgery, was 46 [effectiveness was positive in 92% patients], while it was 33 [effectiveness was positive in 66% patients] in TA group. A significant difference between effectiveness of both anesthetic groups was observed. [P = 0.001]. It is observed that topical anesthesia in cataract surgery is a simple, safe and noninvasive technique but it cannot be proposed as a very good alternative to retrobulbar anesthesia in cataract surgery of all patients regarding its effectiveness interms of pain relief
