Purpose Detecting the accuracy of various posterior elevation (PE) indices of Pentacam HR, and correlating them with some possibly related factors or parameters, in a cohort with early keratoconus (KC). Methods A cross sectional study that was conducted at Eye World Hospital, Egypt. One hundred and two corneas were enrolled, including two groups; group 1 (50 corneas) having forme fruste or early KC, and group 2 (52 corneas) for healthy controls. Corneas were scanned using Pentacam HR (Oculus, We...

Purpose This study aims to assess the intra-operator repeatability and correlation of the Pentacam HR (device 1) and Sirius (device 2) in measuring anterior segment parameters and to evaluate the agreement of their readings and therefore their interchangeability in a clinical setting. Methods This is a prospective non-randomized study was conducted on the right eyes of 102 subjects coming to Eye World Hospital, Giza, Egypt. With each machine, four scans were taken by a single examiner. Each devi...

Background: To identify prognostic preoperative and intraoperative factors for anatomical and visual success of idiopathic macular hole (MH) surgery. Methods: We conducted a non-randomized, collaborative multicenter study using data of 4207 MH surgery from 140 surgeons. Main study outcomes were anatomical closure and best corrected visual acuity (BCVA) improvement postoperative at 6-12 months. Results: Information on anatomical success was available for 4138 eyes of 4207 operations. Anatomical c...

PURPOSE: Many topography/tomography devices are available, and their interchangeable use is frequently questioned. This study aimed to compare the analogous indices of Orbscan 3 and Pentacam HR to detect whether the interchangeable use of the 2 devices is feasible. METHODS: This retrospective study was conducted at Eye World Hospital, Giza, Egypt. Displays of Orbscan 3 (Bausch & Lomb; Technolas Perfect Vision GmbH) and Pentacam HR (Oculus Optikegrate) for 660 healthy right eyes were explored for...

PURPOSE: To assess the agreement between Orbscan 3, Pentacam HR and ultrasound pachymetry (Palm Scan AP 2000) in measuring central corneal thickness. METHODS: Prospective observational cross-sectional study of ninety-two eyes of 48 patients with normal corneas was conducted. Central corneal thickness was measured via Pentacam HR, Orbscan 3 and ultrasound pachymetry. Bland-Altman analysis was used to demonstrate agreement between various methods. RESULTS: Ninety-two eyes of 46 subjects were enrol...

Retinopathy of prematurity (ROP) remains a major cause of childhood blindness in developing countries. As childhood and neonatal mortality in Egypt has shown tremendous improvement over the past two decades, it is expected to encounter an increasing number of cases of blindness from ROP in surviving infants unless strict guidelines and cooperation between different involved departments are explicitly set. In this review article, the author highlights the studies conducted and published risk fact...

Background Retinopathy of prematurity ROP is a leading cause of blindness affecting ∼50 000 children worldwide. The incidence of the disease varies among different countries, it is influenced by the level of perinatal care, the existence of screening programs for early diagnosis. Low birth weight BW, small gestational age GA, other antenatal, postnatal risk factors have been identified with their relation to the severity of the disease. Aim The aim of this research was to study the incidence and...
