Background: To compare the safety and efficacy of Ab-externo subretinal bands removal in comparison with the classical Ab-interno approach during pars plana vitrectomy for primary rhegmatogenous retinal detachment.
Methods: Subjects aged 28-62 years with primary RRD complicated by proliferative vitreoretinopathy (PVR) with subretinal bands interfering with retinal flattening were treated by pars plana vitrectomy (PPV) and silicone oil injection. Subretinal bands were removed using the classical AB interno approach through one or more retinotomies in ten patients (group A) and using AB externo approach in twenty cases (group B).
Factors Affecting Predominantly Peripheral Lesion Identification and Grading.

Purpose: The purpose of this study was to determine factors affecting predominantly peripheral lesion (PPL) grading, such as qualitative versus quantitative assessment, device type, and severity of diabetic retinopathy (DR) in ultrawide field color images (UWF-CIs).
Methods: Patients with DR had UWF-CI qualitatively graded for PPL using standardized techniques and had hemorrhages/microaneurysms (H/Mas) individually annotated for quantitative PPL grading on two different ultrawide field devices.
Results: Among 791 eyes of 481 patients, 38.
Purpose: To describe a novel technique to use the NGage® Nitinol Stone Extractor for large IOFB extraction.
Methods: We conducted a retrospective case series study by reviewing the data of 4 eyes with retained large IOFB extracted with the use of the NGage® Nitinol Stone Extractor. The study was conducted in a single tertiary referral center on four eyes of four patients with large retained IOFB.
Purpose: To describe and evaluate a novel technique of pars plana vitrectomy (PPV) under chandelier illumination which is aided with the vital dyes and perfluorocarbon liquids for the management of the complex diabetic vitrectomy cases.
Methods: We conducted a prospective interventional comparative study on 40 eyes of 36 patients with advanced diabetic eye disease requiring PPV. The study was conducted in a single tertiary referral center.
Purpose: To evaluate the efficacy of human amniotic membrane in promoting closure of macular holes coexisting with rhegmatogenous retinal detachment.
Methods: This is a retrospective case series of 14 eyes (14 patients) with macula off retinal detachment. These patients had a macular hole coexistent with peripheral retinal breaks.
Purpose: In this study, we describe a new surgical technique for the treatment of refractory DME. The technique consists of vitrectomy with ILM peeling with a subretinal injection of ranibizumab.
Methods: This is a prospective interventional noncomparative study including patients with refractory DME.
Purpose: To describe a new method of ILM staining with TB under perfluorocarbon in cases of full thickness idiopathic macular hole using the inverted ILM flap technique.
Methods: This study was a prospective interventional case series that included 42 eyes of 42 patients who had full thickness idiopathic macular hole with a minimum diameter more than 400 µm. Patients consecutively underwent vitrectomy with inverted ILM flap technique using the modified ILM staining method.
Purpose: To assess the outcome of sutureless encirlcing number 41 band and transscleral laser retinopexy in uncomplicated rhegmatogenous retinal detachment (RRD), using a wide-angle viewing system (WAVS) and chandelier endoillumination.
Methods: Prospective intervention study included 30 eyes of 30 patients presenting with RRD of recent onset indicated for SB. All cases were treated by sutureless encircling number 41 band and transscleral laser retinopexy.
Purpose: Many patients describe more rapid recognition of objects after surgical procedures for nystagmus; however, this "recognition time" is not reflected in the parameters typically studied in these patients. The purpose of this study is to assess the effect of nystagmus surgery on visual acuity and recognition time.
Methods: In this prospective, interventional, comparative case series, patients with nystagmus were divided into two groups.
Background: Bancroftian filariasis is focally endemic in Egypt. There have been many reports of intraocular filariasis; the question of why one filarial nematode should cause ocular disease while another does not may be related to the behavior of the microfilaria and the location of the cross-reacting ocular antigen.
Methods: A 35-year-old woman with a white worm approximately 3 disk diameters in length penetrating the left macula, moving in the vitreous cavity, with a part of its length in the vitreous cavity while the rest was embedded subretinally, is described.
Introduction: A-scan ultrasound is currently the most widely used technique for axial length measurement; however, this method is not optimal in silicone-oil filled eyes. Two techniques that may be more accurate for axial length measurements in these eyes are intraoperative measurement of axial length after silicone oil removal or measurement by Laser interferometry using the IOL Master. The purpose of this study is to evaluate and compare the accuracy of both intraoperative biometry and partial coherence interferometry in silicone oil-filled eyes.
