Purpose: To describe a novel technique of macular hole (MH) repair and compare it to the perfluorocarbon liquid (PFCL)-assisted temporal internal limiting membrane (ILM) flap technique.
Methods: Twenty-two eyes of 22 patients with MH were randomized on a 1:1 basis into two groups. Group A cases were treated using the Flip and Fix technique, in which the single-layer ILM flap was flipped, flattened over the macula using PFCL, and fixed in place using two drops of autologous nonheparinized blood over the superonasal and inferonasal edges of the flap (away from the MH center).
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.
Background: Retinopathy of prematurity (ROP), a leading cause of childhood blindness, is diagnosed through interval screening by paediatric ophthalmologists. However, improved survival of premature neonates coupled with a scarcity of available experts has raised concerns about the sustainability of this approach. We aimed to develop bespoke and code-free deep learning-based classifiers for plus disease, a hallmark of ROP, in an ethnically diverse population in London, UK, and externally validate them in ethnically, geographically, and socioeconomically diverse populations in four countries and three continents.

Methods: All diabetic patients attending the general ophthalmology clinics (Group 1), diabetic internal medicine clinics (Group 2), or reached out in the local communities (Group 3) were eligible to participate. Fundus photographs were graded according to the Scottish DR grading system by three independent UK-certified graders.
Purpose: To evaluate current practice patterns for Egyptian ophthalmologists in the diagnosis of diabetic retinopathy (DR) and explore potential implications of these approaches on management.
Methods: Cross-sectional survey conducted in Egypt amongst practicing ophthalmologists.
Results: The study had 203 responses (~6% of all Egyptian ophthalmologists).
Purpose: The G-ROP model was proposed to improve the retinopathy of prematurity (ROP) screening efficiency. It is based on gestational age, birth weight and postnatal weight gain. The current study aimed to validate the G-ROP model's ability to predict ROP in cohorts of premature infants from Egypt and the United Kingdom (UK).

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.
