Objective: We assessed the predictive efficacy of automatically quantified retinal vascular tortuosity from the fundus pictures of patients with sickle cell disease (SCD) without evident retinopathy.

Methods: Retinal images were obtained from 31 healthy and 31 SCD participants using fundus imaging and analyzed using a novel computational automated metric assessment. The local and global vessel tortuosity and their relationship with systemic disease parameters were analyzed based on the images.

Article Synopsis
  • Cataract surgery is the most common surgery done to help people see better, but it can sometimes lead to a serious problem called retinal detachment (RD), which can harm eyesight.
  • A big study looked at over 5 million patients and found that about 37,000 of them experienced RD after surgery, which is about 0.66 cases for every 100 patients.
  • The study also showed that men are more likely to get RD after cataract surgery than women.

Purpose: To determine the earliest characteristics of retinal and optic disc alterations in diabetic children without diabetic retinopathy (DR) changes by using optical coherence tomography angiography (OCTA).

Settings And Design: This was a prospective, non-interventional case-control study that involved 25 patients with type 1 diabetes mellitus (T1DM) without clinical signs of DR and a demographically similar group of 25 healthy children as the control.

Methods: The retina and optic disc were examined using OCTA.

Article Synopsis
  • The study examined the presence of sickle cell maculopathy in children with sickle cell disease (SCD) aged 5 to 18 years through optical coherence tomography angiography (OCTA).
  • Findings revealed that the SCD group had significantly thinner parafoveal thickness, smaller parafoveal volume, and lower deep capillary plexus density compared to a control group of healthy participants.
  • Additionally, the study found that platelet levels were negatively correlated with parafoveal and perifoveal thickness and density, suggesting early macular microvascular alterations in asymptomatic SCD patients.

Objectives: To assess the optic disc parameters in healthy Saudi children.

Methods: This study recruited 85 children who were medically free, born full-term, cooperative, and aged 3-17 years. The children underwent a thorough ophthalmological examination (visual acuity, refraction post-cycloplegia, fundus photography) at the ophthalmology clinic of King Abdulaziz University Hospital, Jeddah.
