Examination of the sclerotomy sites after pars plana vitrectomy by ultrasound biomicroscopy

This present study aimed at studying different changes that could occur at the sclerotomy sites following pars plana vitrectomy by the use of ultrasound biomicroscopy. Ultrasound biomicroscopy [UBM] was used for examinations of slcerotomy sites in 60 eyes of 60 patients after pars plana vitrectomy. Different ultrasound biomicroscopic characteristics for these patients 8-10 weeks post operatively ranging from complete healing, gaping to fibrovascular proliferation. UBM is helpful in detecting complications at the sclerotomy sites after pars plana vitrectomy

Peeling of internal limiting memberane in the management of full-thickness idiopathic macular hole

Purpose: To evaluate the effectiveness of removal of the internal limiting membrane [ILM] in the treatment of full-thickness idiopathic macular hole [MH]. 13 consecutive eyes of 11 patients with full-thickness idiopathic macular hole were recruited for a non-comparative retrospective study. All eyes underwent pars plana vitrectomy, staining of ILM with indocyanine green [ICG], ILM maculorhexis, fluid-air exchange, intravitreous gas tamponade and positioning face down. The outcome measures were disappearance of the submacular fluid, anatomical closure of the hole, visual acuity, associated findings and complications. All patients had postoperative follow up period of >/= 6 months. Primary closure of the macular hole was successfully achieved in 11[84.6%] of the 13 eyes with one operation. Of the 2 macular holes that were open, one underwent repeat surgery. Ultimately, 12 [92.3%] eyes had closure of the macular holes. Nine [69%] of 13 eyes had improvement in the visual acuity of at least two Snellen lines. Complications attributed to removal of ILM were minor hemorrhages and retinal edema that resolved spontaneously. Postoperative ICG staining of the lens capsule and papillary borders had been observed in 2 [15%] eyes. Complications related to the operations included retinal tears and retinal detachment in one [7.6%] eye. Conclusions: peeling of ILM is an important development in successful management of macular hole. To overcome the poor visibility of the ILM, staining of the ILM with ICG is helpful to allow easier and atraumatic removal of ILM
