Ocular biometry, anterior chamber morphometry, and their relationship with serum ferritin levels in children with beta thalassemia major.

Background: Ocular biometry and anterior segment evaluations are important to determine ocular development and pathological changes, especially in thalassemia patients in Mediterranean countries such as Turkey.

Objectives: The objectives of this study were to compare ocular biometry and anterior segment parameters in children with thalassemia major and healthy controls and to examine the relationship between ferritin levels, anthropometric measurements, and ocular parameters.

Design: This is a prospective case-control study.

Usability of Real-Time Elastography for the Diagnosis of Primary Open Angle and Pseudoexfoliation Glaucoma.

Objectives: This study aims to investigate real-time elastography (RTE) use in the evaluation of the optic nerve head (ONH) and peripapillary structures for the diagnosis of primary open angle (POAG) and pseudoexfoliation (PEX) glaucoma.

Methods: This case-controlled study included 30 patients with POAG, 30 patients with PEX glaucoma, and 30 age-matched control subjects. All of the participants underwent comprehensive ophthalmological examinations covering vessel density of optic nerve and retinal nerve fiber layer (RNFL) thickness measurements with optical cohorence tomography angiography and mean deviation (MD) measurements with Humphrey II Perimetry Visual Field Analyzer.

Investigation of ocular microstructural changes according to disease severity in patients with chronic obstructive pulmonary disease.

Objective: To investigate retinal nerve fibre layer (RNFL) thickness and vascular density alterations in the retina and optic disc in patients with chronic obstructive pulmonary disease (COPD).

Methods: A total of 66 COPD patients and 54 age- and sex-matched healthy individuals were enrolled in this prospective cross-sectional study. The COPD patients were divided into 3 subgroups (mild, moderate, and severe COPD) based on spirometric parameters as per the Global Initiative for Chronic Obstructive Lung Disease guideline.

Changes in retinal and choroidal capillary dynamics in patients with multisystem inflammatory syndrome in children.

Purpose: To evaluate patients with multisystemic inflammatory syndrome in children (MIS-C) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection using optical coherence tomography angiography (OCTA) during and after resolution of inflammation to investigate the effect of this entity on the retinal and choroidal circulation.

Methods: The study included 38 eyes of 19 patients diagnosed as having MIS-C between March 2021 and June 2021. OCTA measurements of choroidal thickness and vessel density in the radial peripapillary capillary plexus (RPCP), superficial capillary plexus (SCP), and deep capillary plexus (DCP) obtained at time of diagnosis and 60 days later were compared.

Evaluation of subclinical ocular involvement in patients with deficiency of adenosine deaminase 2 (DADA2).

Purpose: To evaluate changes in the peripapillary, macular, and choroidal microvasculature in the eyes of patients with deficiency of adenosine deaminase 2 (DADA2) and no clinical signs of ocular involvement.

Methods: The study included 12 eyes of 12 patients with DADA2 and 24 eyes of 24 healthy subjects. The foveal avascular zone (FAZ), macular vessel densities (VDs) in the superficial and deep retinal capillary plexuses, peripapillary VDs, and choroidal thickness were evaluated by optical coherence tomography angiography (OCTA).

Optical cohorence tomography angiography findings in carotid artery stenosis.

Aim: To investigate vascular density (VD) changes in the superficial (SCP) and deep capillary plexus (DCP), radial peripapillar capillary plexus (RPCP), Foveal avascular zone (FAZ) and thickness changes of peripapillary retinal nerve fiber layer (ppRNFL) and choroid (CT) using optical coherence tomography angiography (OCTA) ipsilateral eyes of patient with internal carotid artery stenosis (ICAS) and to compare the obtained values with kontralateral eyes of patients with İCAS and healthy individuals.

Methods: This prospective cross-sectional case-control study was conducted in 43 patients with a diagnosis of unilateral ICAS and 47 age- and sex-matched healthy subjects. The patients were divided into three groups.

Optical coherence tomography angiography in healthy children: normative data and age-related changes in microvascular structure of the optic disk and macula.

Purpose: To determine normative data and reference ranges according to age groups by measuring the foveal avascular zone (FAZ), superficial capillary plexus vascular density (SCP-VD), deep capillary plexus vascular density (DVP-VD), radial peripapillary capillary plexus vessel density (RPC-VD), and peripapillary retinal nerve fiber layer (ppRNFL) in healthy children and to determine the age and sex-related changes of these values.

Methods: This prospective study included data from 370 eyes of 370 healthy children (202 girls, 168 boys) aged 7-18 years. Participants were divided into four groups according to their age.

Cold-induced Vascular Changes in the Macula, Optic Disc and Choroid in Children with Raynaud's Phenomena.

Aim: To investigate changes in retinal and choroidal vessels in children with primary and secondary raynaud's phenomena(RP).

Methods: Measurements were performed by optic coherence tomography angiography before as well as during and 10 minutes after the immersion of one hand in ice water.

Results: Primary RP patients exhibited enlargement of the foveal avascular region and decrease in vessel density in the parafoveal superficial capillary plexus (SCP) during cold exposure, but values returned to normal when the hands were removed from the cold water.

Effectiveness of Intraductal Meibomian Gland Probing in Addition to the Conventional Treatment in Patients with Obstructive Meibomian Gland Dysfunction.

: To evaluate the effectiveness of intraductal meibomian gland probing in addition to conventional treatment for the management of obstructive meibomian gland dysfunction (O-MGD).: Totally, 40 patients were divided into two groups to receive either conventional treatment alone (group 1: 40 eyes of 20 patients) or conventional treatment plus probing (group 2: 40 eyes of 20 patients). The ocular surface disease index score, Schirmer 1 test, tear film break-up time, Oxford grading of ocular surface, meibum expressibility, and quality scores were evaluated baseline and compared with the end of treatment (day 30 and day 90).
