RESUMO
Objective: To assess the visual outcome and complications of Combined Pars Plana Lensectomy- Vitrectomy in hereditary ectopia lentis
Study Design: Prospective observational study
Settings: Al-Ibrahim Eye Hospital, Isra Postgraduate Institute of Ophthalmology, Karachi; from Jan' 2004 to Dec' 2007
Subjects and Methods: Forty eyes of 23 patients diagnosed as having hereditary ectopia lentis were included in the study. All the cases were worked up according to the standard protocol and were operated upon. The surgical procedure adopted was pars plana lensectomy with core vitrectomy. Endolaser photocoagulation was performed in selected cases
Results: Forty [40] eyes of 23 patients with ectopia lentis of hereditary type were included in the study. Seventeen patients had bilateral and 6 patients had unilateral ectopia lentis. There were 8 male and 15 female patients. Age range was 5 - 29 years. Preoperative visual acuity was 6/12 - 6/18 in 4 [10%] eyes; 6/24 - 6/60 in 28 [70%] eyes and < 6/60 in 8 [20%] eyes. Postoperative corrected visual acuity was 6/6 - 6/9 in 28 [70%] eyes; 6/12 - 6/18 in 4 [10%] eyes; 6/24 - 6/60 in 6 [15%] eyes and less than 6/60 in 2 [5%] eyes. Intra-operative complications were accidental iris injury in 1 eye and dropped lens fragment into the vitreous cavity in 1 eye. Post-operative complications were transient ocular hypertension in 2 eyes and persistant postoperative uveitis and vitritis in 1 eye
Conclusion: Pars plana approach for management of ectopia lentis is a safe and effective method of treatment
RESUMO
Objective: to determine the risk factors, characteristics and presentation of Giant Retinal Tear
Design: descriptive case-series study
Setting: Al-Ibrahim Eye Hospital, Isra Postgraduate Institute of Ophthalmology, Karachi; from January 2001 to July 2007
Methods: all patients diagnosed as having Giant Retinal Tear [GRT] in the Surgical Retina Clinic, were included in the study. The details of patients' demographics, ocular history, risk factors, refractive status, ocular examination, systemic examination, treatment offered and final outcome were recorded in a specially designed proforma
Results: a total number of 42 eyes of 38 patients with GRT was included in the study. The causative factors in our study were vitreo-retinal degeneration, blunt ocular trauma and complicated cataract surgery. Myopia was the most common ocular risk factor. Most of the patients presented to our hospital after 4 weeks of onset of symptoms with total retinal detachment, advanced proliferative vitro retinopathy and poor visual acuity. Pars Plana Vitrectomy with Silicone oil tamponade, with or without Scleral Buckling was performed in 35 eyes
Conclusion: the major risk factors for GRT are peripheral retinal degenerations, high myopia, ocular trauma, GRT in the fellow eye, family history of retinal detachment, complicated cataract surgery and connective tissue disorders. Various socio economic issues and inadequate patient counseling are responsible for late presentation of patients that leads to extensive PVR
