Complications of conventional scleral buckling occuring during and after treatment of rhegmatogenous retinal detachment.
J Coll Physicians Surg Pak Jan ;20(5):321-6.

Objective: To identify and determine the frequency of the intra-operative and early postoperative complications of Conventional Scleral Buckling (CSB) as the primary surgical intervention in patients with Rhegmatogenous Retinal Detachment (RRD). Study Design: A quasi-interventional study. Place and Duration of Study: Khyber Institute of Ophthalmic Medical Sciences (KIOMS), Postgraduate Medical Institute (PGMI), Hayatabad Medial Complex (HMC), Peshawar, from April 2005 to June 2006. Methodology: Fifty consecutive patients who underwent CSB and fulfilled the inclusion criteria, were included in the study. Operative details and any intra-operative complications were noted. The patients underwent another detailed clinical examination and pain assessment on the first postoperative day. All the patients were followed-up minimum for 3 months. Postoperative complications were identified and recorded. The data was analyzed on SPSS 12.0 for measures of central tendency and dispersion. Results: There were 36 male and 14 female subjects. Mean age was 37.18±20.045 years. Encirclement (56%) was the most frequently used CSB technique. Sixteen (32%) patients had at least one intra-operative complication. Intra-operative complications were iatrogenic scleral break (2%), accidental Sub Retinal Fluid (SRF) drainage (8%), choroidal haemorrhage (2%), subretinal haemorrhage (14%), retinal incarceration (2%), vitreous haemorrhage (6%), raised (4%) or very low (2%), intra-operative IOP and hyphema (2%). Postoperative complications included systemic complications (24%), choroidal detachment (8%), vitreous haemorrahge (16%), raised IOP (22%), angle closure (2%), conjunctivitis (4%), orbital cellulitis (2%), suspected endophthalmitis (2%), ocular movement disorders (2%) and explant exposure (6%). Mean refractive change in spherical equivalent was -1.478±0.698 D. Final re-attachment rate was (82%) and final BCVA of > 6/60 was achieved in 62% of the subjects in the treated eyes. Conclusion: CSB is a safe and effective option for treating uncomplicated RRD, but it is associated with certain complications. Sub-retinal bleed was the most common intra-operative complication. Raised IOP was most the common early postoperative complication followed by choroidal detachment.
