Optic nerve head vascular variations in pseudoexfoliative and primary open-angle glaucoma.

Purpose: The purpose of this study was to assess the optic nerve head microvascular changes in pseudoexfoliative and primary open-angle glaucoma and define the relationship between vessel density and retinal nerve fiber layer thickness.

Methods: This observational cross-sectional study assessed 72 eyes with primary open-angle glaucoma, 41 eyes with pseudoexfoliative glaucoma, and 60 healthy eyes. On the basis of optic nerve head-centered, 4.

Effects of obstructive sleep apnea on retinal microvasculature.

Aim: To detect retinal microvascular variations in obstructive sleep apnea syndrome patients.

Methods: This prospective, observational case-control study included healthy controls and patients with mild, moderate, and severe obstructive sleep apnea syndrome. Vascular parameters, foveal avascular area, and flow areas in macula-centered, 6.

The iridocorneal angle and related anterior segment structures in pediatric anisohyperopic amblyopic eyes.

Objectives: We aimed at investigating the iridocorneal angle, anterior segment structural differences, and their relationship in pediatric anisohyperopic amblyopic eyes.

Methods: This study was designed as an observational case-control study. We prospectively evaluated the pediatric patients who were newly diagnosed with hyperopic anisometropic amblyopia.

The effect of vitamin D deficiency on the retinal microvasculature: an observational case-control study.

Purpose: To determine the effects of vitamin D deficiency on retinal microvascularity using optical coherence tomography angiography.

Methods: This study was designed as an observational case-control study. Ninety-eight eyes of patients with vitamin D deficiency and 96 eyes of healthy participants with serum vitamin D level >30 ng/mL were studied.

Refractive outcomes of table-mounted and hand-held auto-refractometers in children: an observational cross-sectional study.

Background: To compare the refractive results of hand-held and table-mounted autorefractors.

Methods: We designed this study as an observational, cross-sectional study. We compared the mean spheric and cylinder power, spherical equivalent, Jackson cross-cylinder values, determined the limits of agreement (LoA), and evaluated the reliability of two autorefractors.

Microvascular differences in amblyopic subgroups: An observational case-control study.

Purpose: To determine retinal microvascular differences among amblyopic subgroups and compare them with control eyes.

Study Design: This study was designed as an observational case-control study.

Methods: Twenty-three strabismic, 23 anisometropic, 22 meridional, 22 ametropic amblyopic eyes, and 24 healthy control eyes were included.

Optic nerve head microvascular changes after phacoemulsification surgery.

Background: To determine optic nerve head (ONH) microvascular changes detected by optical coherence tomography angiography (OCTA) and intraocular pressure changes (IOPs) after uncomplicated phacoemulsification surgery.

Methods: The study was designed as a prospective observational study. Twenty-four eyes were included.

Microvascular changes in amblyopic eyes detected by optical coherence tomography angiography.

Purpose: To investigate retinal microvascular findings detected by optical coherence tomography angiography (OCT-A) in amblyopic eyes compared with normal eyes.

Methods: A total of 23 amblyopic (strabismic, ametropic, anisometropic, and meridional amblyopia) and 22 normal eyes were included in this prospective observational, comparative study. All patients underwent complete ophthalmological examination and OCT-A imaging.
