Purpose. To describe the normative values of corneal endothelial cell density, morphology, and central thickness in healthy Turkish eyes. Methods. Specular microscopy was performed 252 eyes 126 volunteers (M : F, 42 84). Parameters studied included mean density (MCD), area (MCA), coefficient variation (CV) size, percentage hexagonal cells, (CCT). Results. The age 44.3 ± 13.5 (range, 20 to 70) years. There a statistically significant decrease MCD (P < 0.001; correlation, -0.388) -0.199) with...
Background: To determine the agreement of central corneal thickness (CCT) measurements taken with ultrasonic pachymetry (USP), spectral domain optical coherence tomography (SD-OCT) and noncontact specular microscopy (NSM).Methods: A prospective, observational, cross-sectional study was performed in outpatient ophthalmology clinic. CCT measured a total 147 eyes consecutive healthy patients USP, NSM, SD-OCT. Same examiner all examinations. Bland–Altman plots were used to evaluate between...
Purpose: To evaluate the effects of hunger and thirst on corneal biomechanical structural parameters during Ramadan fasting.Materials Methods: Corneal properties intraocular pressures 29 eyes healthy subjects were evaluated by Reichert ocular response analyzer; anatomical cornea anterior eye chamber same scanned with Oculus Pentacam segment analyzer. Each has been at 8 am 4 pm both 1 month after Ramadan. Changes subjects’ weight calculated their relationship was assessed.Results: Intraday...
To investigate the corneal biomechanical properties and anterior segment parameters in patients with obstructive sleep apnea syndrome (OSAS).Fifty-four eyes of 54 OSAS 20 healthy subjects were included. Patients mild moderate (Respiratory Disturbance Index [RDI] <30) enrolled group 1, those severe (RDI≥30) 2 controls 3. Corneal including hysteresis (CH), resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), corneal-compensated (IOPcc) measured ocular response analyzer....
The aim of this study is to investigate the possible corneal biomechanical changes in patients with angioid streaks and understand if calcified thickened Bruch's membrane associated influences elasticity eye intraocular pressure.Twelve eyes 12 (six males six females) age- sex-matched healthy volunteers were enrolled study. Corneal hysteresis (CH), resistance factor (CRF), compensated pressure (IOPcc) Goldmann-correlated (IOPg) measured an Ocular Response Analyzer (ORA). Central thickness...
To identify the peripapillary retinal nerve fiber layer, total macular, ganglion cell and inner plexiform layer thicknesses in children with high hyperopia using spectral domain optical coherence tomography.Twenty-one 20 controls were enrolled this study. Subjects spherical equivalent +5.0 D or higher evaluated study group subject between +0.25 +2.0 control group. The thickness, macular measured a tomography, results compared groups.The nasal inferior quadrant global thickness significantly...
Purpose. To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement. Methods. Twenty-four consecutive patients with HFS and 25 age- gender-matched randomly selected eyes healthy volunteers underwent corneal pachymetry IOP measurements using Goldmann applanation tonometer (GAT) noncontact (NCT). were performed before (during HFS) 2 weeks after Botox injections in without injections. Results. There was no statistical difference between involved eye side...
Purpose: To determine retinal sensitivity and fixation in children with anisometropic amblyopia using macular analyzer integrity assessment (MAIA) microperimetry (CenterVue). Methods: Amblyopic non-amblyopic eyes of 39 the diagnosis were compared MAIA terms average threshold, indexes (P1 P2), bivariate contour ellipse area (BCEA) for 95% 63% points. The correlations between visual acuity parameters also analyzed. Results: mean threshold was 26.6 ± 5.9 dB amblyopic 28.6 1.9 fellow ( P =...
Background: Leber congenital amaurosis (LCA) is both genetically and phenotypically heterogeneous group of retinal disorder. Mutations in degeneration 3 (RD3) have been reported as an infrequent cause LCA which account for less than 1% all known cases. This case report provides Optical Coherence Tomography (OCT) Fundus Autofluorescence (FAF) findings infant with related to a mutation RD3.Materials Methods: Single retrospective report.Results: TruSight One Expanded Sequencing Panel was...
Amaç: Kornea endotel hücre morfolojisi, yoğunluğu ve merkezi kornea kalınlığının tip 2 diyabeti olan hastalar ile olmayan sağlıklı gönüllülerle karşılaştırılması. Gereç Yöntemler: Bu prospektif klinik çalışmada, diabetes mellitus (DM)'lu 30 hastanın 60 gözü ile, diyabetli 51 gönüllünün 102 çalışmaya alındı. Her bir diyabetik olgu için beden kitle indeksi hesaplandı, açlık kan şekeri (AKŞ) HbA1c düzeyleri ölçüldü. Kontrol grubuna, kez yapılan AKŞ ölçümü <100 mg/dL bireyler dâhil edildi....
Amaç: Parkinson hastalarını retina sinir lifi tabakası (RSLT) ve makula kalınlıkları yönünden incelemek sağlıklı kontrol grubu ile karşılaştırmak Yöntem: tanısı alan yaş ortalaması 69,2±8,2 yıl olan 25 hasta sistemik hastalık öyküsü bulunmayan 67,2±7,1 19 göz bulguları açısından değerlendirildi. Hastalara Optik Koherens Tomografi (OKT) RSLT kalınlık ölçümleri yapıldı. Gruplar elde edilen veriler Student t testi karşılaştırıldı. Bulgular: İnferior kadran grubunda 133,1±19,3 μm, ise 145,1±19,6...
To investigate the effect of cycloplegia on anterior segment structures in keratoconus and forme fruste patients using corneal topography.In this study, 40 with (group 1), 2), healthy subjects 3) were evaluated prospectively. Flat keratometry (K) value (K1), steep K (K2), mean (Kmean), maximum (Kmax), astigmatism value, chamber depth (ACD), symmetry index front, back, thinnest thickness, central thickness volume measured Sirius topography before after cycloplegia. Results compared one way...
Objective: To determine the prevalence of color vision deficiency, ratio deutan/protan and distribution severity deficiency among Turkish children to evaluate usability Color Assessment Diagnosis (CAD) test in children. Material Methods: A total 1374 (627 girls 747 boys) age 6-16 years were included this study. The first 15 plates Ishihara used screen for deficiency. Those who made three or more errors had their examined using CAD type boys girls, deutan protan deficieny loss calculated....
Choroidal hemorrhages (CH) result from rupture of choroidal vessels leading to extravasation blood into the suprachoroidal space. In this study, we aimed understand hemodynamics CH by developing a purpose-built scale model vasculature and calculating stress levels in under different conditions.We modeled using rubber tube 10 cm length 1 diameter that was wrapped with conductive thread enable measurement at walls tube. Stress across were continuously measured systemic intravascular pressure...
