The potential of serum elabela levels as a marker of diabetic retinopathy: results from a pilot cross-sectional study.

Background: The aim of this study is to examine the relationship between elabela (ELA), a recently identified peptide also known as Toddler and Apela, and diabetic retinopathy (DR). ELA, produced in various tissues, acts as a natural ligand for the apelin receptor (APJ). Upon reviewing the existing literature, only one study was found investigating ELA, one of the APJ ligands, in the pathogenesis of DR.

Evaluation of retinal and choroidal vascular structures in obsessive-compulsive disorder.

Purpose: To evaluate the optical coherence tomography-angiography (OCT-A) findings and choroidal vascularity index (CVI) of patients followed with a diagnosis of obsessive-compulsive disorder (OCD) by comparing them with the healthy control group (HCG).

Methods: This prospective study included 33 patients diagnosed with OCD and 32 HCG patients who followed up for at least 3 months. OCT-A images were obtained to evaluate the microvascular circulation, and enhanced HD line images were obtained for the CVI calculation of all patients.

Co-assessment of OCT-A and choroidal vascularity index data in multiple sclerosis patients.

Objective: To evaluate optical coherence tomography-angiography (OCT-A) findings and choroidal vascular index (CVI) in patients with multiple sclerosis (MS).

Methods: 113 patients, including multiple sclerosis patients with optic neuritis attack (MSON+) and no optic neuritis attack (MSON-) and healthy control group (HCG), participated in this cross-sectional study. OCT-A images of all patients were taken and CVI was calculated.

Investigation of Retinal Vascular Parameters and Choroidal Vascular Index in Patients Developing Hyphema After Unilateral Blunt Trauma.

Background: To evaluate retinal and choroidal vascular changes in cases with hyphema after blunt ocular trauma that did not cause globe rupture or any retinal pathology.

Methods: This cross-sectional study included 29 patients who developed hyphema after unilateral blunt ocular trauma (BOT). The other healthy eyes of the same patients were evaluated as the control group.
