Evaluation of the effects of different mydriatic drops used on choroidal vascularity in healthy children.

Purpose: To evaluate the effects of mydriatics drops used primarily in routine eye examinations on the choroid tissue, which has a dense vascular network in the eye.

Methods: This prospective observational study included 90 eyes of 90 healthy children. Optical coherence tomography (OCT) images were obtained for all children before dilation.

Retinopathy of prematurity screening: can the examination time be reduced?

Clinical Relevance: Retinopathy of prematurity (ROP) is a significant cause of childhood blindness. Screening examinations that maintain accuracy, while improving the experience for families, could increase adherence to follow-up and decrease workload.

Background: Traditional ROP screening examinations are known to be uncomfortable for babies and stressful for parents.

Assessment of vision-related quality of life and depression in patients with age-related macular degeneration.

Purpose: To evaluate the effect of age-related macular degeneration (AMD) on vision-related quality of life (VRQOL) and depression levels.

Methods: This cross-sectional study included 143 patients who are being followed up with a diagnosis of AMD. The Turkish versions of the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) and Geriatric Depression Scale-15 (GDS-15) were directed to the patients.

Examination of the Corneal Endothelium in Pediatric Patients With COVID-19.

Purpose: To investigate the effects of coronavirus disease 2019 (COVID-19) infection on the corneal endothelium in children.

Methods: This retrospective study included 46 pediatric patients with COVID-19 infection and 38 healthy controls. Specular microscopy measurements were analyzed, and measurements were obtained from images showing at least 100 cells with clear borders.

Evaluation of the retina with optical coherence tomography angiography (OCTA) in patients with coronavirus (COVID-19) infection.

Purpose: The goal of this study is to compare the optical coherence tomography angiography (OCTA) findings in Coronavirus (COVID-19) positive adult and pediatric patients with those of healthy volunteers with the same demographic characteristics.

Methods: The right eye of 157 adults infected with covid, 168 healthy adult volunteers, 40 children (6-18 years of age) infected with covid, and 44 healthy children (6-18 years of age) were included in this prospective study. All participants underwent ophthalmological examination and OCTA.

Vascular changes in macula, optic disc, and choroid in Wilson's disease: A cross-sectional optical coherence tomography angiography study.

Purpose: To evaluate the changes in the retinal and optic disc (OD) microcirculation in patients with Wilson's disease (WD) using optical coherence tomography angiography (OCTA).

Materials And Methods: This cross-sectional comparative study included 35 eyes of 35 WD patients (study group) and 36 eyes of 36 healthy participants (control group). The patients with WD were divided into subgroups based on the presence of Kayser-Fleischer rings.

Is serum vitamin D associated with diabetic retinopathy and its severity or with diabetes itself ?

Clinical Relevance: Vitamin D (VitD) deficiency, which is found in approximately one-third of the population of the world, may play a role in the pathogenesis of diabetic retinopathy. Physicians following diabetes patients should be aware of this relationship and should refer patients to for ophthalmic care for control in a timely manner.

Background: Diabetic retinopathy is one of the most common complications of diabetic microvascular disease.

Evaluation of YouTube videos as a patient information source on intravitreal injection procedures.

Purpose: To evaluate the content, reception and quality of YouTube videos on intravitreal injection (IVI) procedures as an educational resource for patients.

Methods: Our study was a retrospective, cross-sectional, register-based study. The terms "intravitreal injection," "intravitreal injection treatment," "eye injection," "eye injection treatment," "dexamethasone intraocular injection," "anti-VEGF injection," "Ozurdex®," "Lucentis®," and "Eylea®" were searched on YouTube.

Intraocular pressure outcomes after 23-G vitreoretinal surgery with two different transconjunctival sutureless sclerotomy techniques: vertical versus tunnel entry.

Purpose: Comparison of postoperative intraocular pressure (IOP) course and early complications in 23-gauge (23-G) pars plana vitrectomy (PPV) using vertical entry sclerotomy and scleral tunnel sclerotomy in uncomplicated rhegmatogenous retinal detachment (RRD).

Method: A prospective, randomized, comparative, interventional clinical trial of 103 23-G vitrectomy cases using two different transconjunctival sutureless sclerotomy techniques performed by a single vitreoretinal surgeon for uncomplicated RRD. Fifty-two eyes underwent PPV using a three-port 23-G single stage, vertical trocar entry without creating a scleral tunnel (Group 1), while in 51 eyes, a two-stage, oblique trocar entry with creation of a scleral tunnel was performed (Group 2).

Outcomes of customized topographic guided epithelial debridement for corneal collagen cross-linking.

Purpose: To evaluate the outcomes of corneal collagen cross-linking performed with customized epithelial debridement technique in progressive keratoconic corneas.

Materials And Methods: Forty eyes of 40 patients were included in the study. We performed an ophthalmologic examination and recorded the uncorrected visual acuity, best corrected visual acuity (BCVA), central corneal thickness at the thinnest point (t-CCT), flat meridian keratometry (K1), steep meridian keratometry (K2), endothelial cell density (ECC), hexagonal cells (HEX), and coefficient of variation of cell areas (CV) measured preoperatively and at the 1st, 3rd, 6th and 12th months postoperatively.
