Aims: The current study compared a novel technique of scleral indentation using the self-retaining Leyla retractor to the conventional scleral self-indentation with the chandelier light.
Methods: Patients with rhegmatogenous retinal detachment were randomized on a 1:1 basis to either have the (Baha) indentation using a tip of a thimble scleral indenter welded to the support for the Leyla retractor system or to have the conventional scleral indentation while using a 25-gauge chandelier light. A video was recorded for the surgery of all the cases and reviewed by another consultant masked to the type of indentation.
Purpose: To assess the anatomical and functional outcomes of intravitreal infusion of methotrexate (MTX) during pars plana vitrectomy (PPV) for proliferative vitreoretinopathy (PVR) associated with rhegmatogenous retinal detachment (RRD).
Methods: Comparative interventional nonrandomized study including consecutive patients who had vitrectomy for RRD. The study included six groups.
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 report a new spectral domain optical coherence tomography (OCT) finding called the pigtail sign. It was found during follow-up of idiopathic macular hole cases after inverted internal limiting membrane (ILM) flap surgery.
Methods: This is a retrospective case series of 12 eyes (12 patients) who underwent inverted ILM flap technique for idiopathic macular hole closure.
Aims: To compare microaneurysm (MA) counts using ultrawide field colour images (UWF-CI) and ultrawide field fluorescein angiography (UWF-FA).
Methods: Retrospective study including patients with type 1 or 2 diabetes mellitus receiving UWF-FA and UWF-CI within 2 weeks. MAs were manually counted in individual Early Treatment Diabetic Retinopathy Study (ETDRS) and extended UWF zones.
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: 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.

Methods: The current study was performed on 30 eyes of 15 male white rabbits. The rabbits were divided into three equal groups.
