Purpose: We aimed to identify the risk factors that may predispose preterm neonates to develop aggressive posterior retinopathy of prematurity (APROP).
Methods: This retrospective case control study included 16 infants with APROP in zone 1 or posterior zone 2. Thirty-four gestational age and birth weight-matched controls with stage 2 or less ROP were included.
Aim: This study described the characteristics and risk factors of neonates who developed retinopathy of prematurity (ROP) and severe treatable ROP in two Egyptian neonatal intensive care units (NICUs).
Methods: This retrospective cohort study comprised 108 preterm neonates who were screened for ROP after being admitted to the two NICUs run by Cairo University Hospital from June 2014 to May 2015. Patients were examined using digital fundus photography and indirect ophthalmoscopy was performed if ROP was detected.
Aim: To assess the ganglion cell complex (GCC) thickness in diabetic eyes without retinopathy.
Methods: Two groups included 45 diabetic eyes without retinopathy and 21 non diabetic eyes. All subjects underwent full medical and ophthalmological history, full ophthalmological examination, measuring GCC thickness and central foveal thickness (CFT) using the RTVue spectral domain-optical coherence tomography (SD-OCT), and HbA1C level.
Purpose: To evaluate retinal sensitivity in children who are on hydroxychloroquine (HCQ) for systemic lupus erythematosus using microperimetry and compare the results with those of the Humphrey visual field (HVF) 10-2 and spectral-domain optical coherence tomography (SD-OCT).
Procedure: A case-control cross-sectional study including 19 patients (less than 18 years old) on HCQ for at least 5 years. Controls were 21 normal children.
