The rapid advancement of computational infrastructure has led to unprecedented growth in machine learning, deep learning, and computer vision, fundamentally transforming the analysis of retinal images. By utilizing a wide array of visual cues extracted from retinal fundus images, sophisticated artificial intelligence models have been developed to diagnose various retinal disorders. This paper concentrates on the detection of Age-Related Macular Degeneration (AMD), a significant retinal condition, by offering an exhaustive examination of recent machine learning and deep learning methodologies.

Design: A cross-sectional case series.
Methods: The study included 56 patients (60 eyes) presented with anterior chamber (AC) granulomas.
Traditional dilated ophthalmoscopy can reveal diseases, such as age-related macular degeneration (AMD), diabetic retinopathy (DR), diabetic macular edema (DME), retinal tear, epiretinal membrane, macular hole, retinal detachment, retinitis pigmentosa, retinal vein occlusion (RVO), and retinal artery occlusion (RAO). Among these diseases, AMD and DR are the major causes of progressive vision loss, while the latter is recognized as a world-wide epidemic. Advances in retinal imaging have improved the diagnosis and management of DR and AMD.
View Article and Find Full Text PDFPurpose: To investigate the UBM characteristics of presumed trematode-induced granulomatous uveitis.
Design: Prospective case series.
Methods: Thirty patients who presented with anterior chamber (AC) granuloma were included.
Purpose: To report visual, refractive, and corneal aberrations after implantation of a new asymmetric intracorneal ring segment (ICRS).
Methods: This was a prospective, multicenter clinical study including 30 eyes of 26 patients with keratoconus. All cases were implanted with an ICRS, named the VISUMRING (VR), which had an arc length of 353 degrees and 2 asymmetric sections that can be customized in base width, length, and thickness.
Purpose: The purpose of this study is to evaluate the efficacy of systemic antiparasitic medications alone or in combination with surgical aspiration in management of presumed trematode-induced anterior uveitis in children.
Patients And Methods: Prospective case series. Children who presented with anterior chamber (AC) granuloma were included in the study.
Aim: To compare Visian lens (model V4c) and Artiflex lens regarding quality (contrast sensitivity) and quantity (efficacy, predictability, safety and stability) of vision in correcting high myopia with recording and analysis of complications.
Methods: The comparative prospective study included 39 eyes of 23 patients with high myopia, 19 eyes had Visian lens implantation (model V4c) and 20 eyes had Artiflex lens implantation. The inclusion criteria were high myopia (higher than 6.

Purpose: To evaluate the results of 4-point scleral fixation of posterior chamber intraocular lenses (PC IOLs) in children.
Setting: Mansoura Ophthalmic Center, Mansoura University, Mansoura, Egypt.
Methods: This retrospective study comprised 20 aphakic eyes of 20 children.
