Age-related changes in reading performance in normally sighted Arabic-speaking adults.

Clinical Relevance: Reading performance is important for evaluating near vision and predicting and prescribing near-vision correction. There is a significant gap in the literature on Arabic reading performance and its associated effects.

Background: Normative data from control participants serve as the baseline for future studies involving groups with specific characteristics.

Ocular parameters alterations after hemodialysis in patients with chronic kidney diseases.

Purpose: To evaluate the effects of hemodialysis (HD) on visual acuity (VA), central corneal thickness (CCT), intraocular pressure (IOP), and macular thickness (MT) in chronic kidney disease (CKD) patients and also to investigate the relationship between the ocular parameters and blood biochemical parameters such as serum albumin, creatinine, sodium, and urea levels.

Methods: A prospective cohort study including a total of 24 CKD patients of both genders (above 18 years old) undergoing HD in XXX was conducted. The participants were divided into three sub-groups based on the primary cause of renal failure, group 1: Hypertensive kidney disease, group 2: Diabetic kidney disease, group 3: Other causes.
