To evaluate the ability of chromatic pupillometry to reveal abnormal pupillary responses light in patients with early-stage primary open-angle glaucoma (POAG) and test whether degree pupillometric impairment correlates structural hallmarks optic nerve damage disease.Cross-sectional study.Forty-six POAG (63.4±8.3 years, 63% male, 87% ethnic-Chinese) 90 age-matched healthy controls (61.4±8.6 34% 89% ethnic-Chinese). Patients had a visual field mean deviation (VFMD) -6 decibels or better on...
Glaucoma leads to permanent vision disability by damaging the optical nerve that transmits visual images brain. The fact glaucoma does not show any symptoms as it progresses and cannot be stopped at later stages, makes critical diagnosed in its early stages. Although various deep learning models have been applied for detecting from digital fundus images, due scarcity of labeled data, their generalization performance was limited along with high computational complexity special hardware...
Context: Congenital glaucoma is a potentially blinding ocular disease of the childhood. Identification possible associated risk factors and may be helpful for prevention or early detection this public health problem. Aims: To demonstrate demographic features congenital subjects. Setting Design: The charts patients referred to Tamcelik Glaucoma Center were retrospectively reviewed through dates 2000 2013. Materials Methods: Analyzed data included diagnosis, age at first presentation, symptoms...
Precis: Inter-ocular comparison of primary angle closure glaucoma subjects with asymmetrical and symmetrical visual field loss, revealed significantly thinner central corneal thickness higher presenting intraocular pressure in the worse eye group. Purpose: To compare inter-ocular clinical biometric parameters angle-closure (PACG) visual-field loss at presentation. Patient Methods: Retrospective study which following data were extracted: (IOP), gonioscopy, mean deviation (MD), (CCT), anterior...
To report the perioperative complications and clinical outcomes after deep anterior lamellar keratoplasty (DALK) using big bubble technique in eyes with stromal corneal dystrophies.Seventy-four of 65 patients who underwent DALK for dystrophies were evaluated this retrospective interventional case series study. Main outcome measures intraoperative postoperative complications, uncorrected visual acuity, best spectacle-corrected spherical equivalent refraction, topographic astigmatism.There 44...
Purpose: To compare ocular biometric and anterior segment parameters between the affected fellow eye in subjects with acute primary angle closure (APAC). Methods: We evaluated 76 unilateral APAC who had undergone bilateral laser peripheral iridotomy before enrollment. Imaging was done using optical coherence tomography a customized software used to measure following: opening distance (AOD750); trabecular–iris space area (TISA750); iris thickness (IT750); curvature (ICURV); (IAREA); chamber...
<h3>Importance</h3> Exfoliation syndrome is a systemic disorder characterized by progressive accumulation of abnormal fibrillar protein aggregates manifesting clinically in the anterior chamber eye. This most commonly known cause glaucoma and major irreversible blindness. <h3>Objective</h3> To determine if exfoliation associated with rare, protein-changing variants predicted to impair function. <h3>Design, Setting, Participants</h3> A 2-stage, case-control, whole-exome sequencing association...
To determine the prevalence of keratoconus (KC) in students and faculty members (aged ≥18 ≤30 years) studying/working at Medical Health Sciences faculties Eskişehir Osmangazi University.Eskişehir University, Eskişehir, Turkey.Prevalence study.Subjects were randomly selected to undergo KC screening using a proportional stratified sampling method. Of 648 invited subjects, 585 (90.3%) responded invitation. The demographic data, medical/family history, habits subjects collected standardized...
Baseline anterior segment imaging parameters associated with incident gonioscopic angle closure, to our knowledge, are unknown.To identify baseline quantitative optical coherence tomography the development of closure after 4 years among participants gonioscopically open angles at baseline.Three hundred forty-two aged 50 or older were recruited participate in this prospective, community-based observational study. Participants underwent gonioscopy and years. Custom image analysis software was...
<b><i>Purpose:</i></b> To evaluate the agreement between reading values of Goldmann applanation tonometer (GAT), Icare Pro rebound (IRT) and noncontact (NCT) in glaucoma patients. <b><i>Methods:</i></b> This cross-sectional study comprised 292 eyes patients selected from a outpatient clinic. The intraocular pressure (IOP) was measured sequentially, at 10-min interval each, following order: NCT, IRT GAT. central corneal thickness (CCT) using...
Inflammatory mediators that infiltrate the corneal stroma after infections, trauma or refractive surgery can trigger transformation of keratocytes into myofibroblasts, resulting in highly irregular collagen deposition and subsequently scarring. Mesenchymal stem cells (MSCs) be used as therapeutic agents to regenerate conjunctival tissue damage, regulate inflammation, reduce development limbal cell failure. The use MSC-derived exosomes a cell-free vector is novel approach. This study aimed...
Background To estimate and compare changes in the Bruch’s membrane opening—minimum rim width (BMO–MRW) area normal, ocular hypertensive glaucoma eyes following acute elevations intraocular pressure (IOP). Methods The optic nerve heads (ONHs) of 104 subjects (31 normals, 20 hypertension (OHT) 53 with primary glaucoma) were imaged using Spectral-domain optical coherence tomography (OCT; Spectralis, Heidelberg Engineering, Germany). IOP was raised twice by applying a force (0.64 n then 0.9 n)...
Précis: Reduction of intraocular pressure (IOP) by latanoprost in treatment-naive eyes is significantly correlated to an increase vessel density (VD) at the optic nerve head (ONH). Purpose: To evaluate effect topical on ocular microvasculature using optical coherence tomography angiography (OCTA). Patients and Methods: In this prospective case-control study, 26 from 18 subjects whom prostaglandin analogue (PGA) 0.005% was initiated were included as cases. 10 out subjects, medication only 1...
The acute biomechanical response of the optic nerve head (ONH) to intraocular pressure (IOP) elevations may serve as a biomarker for development and progression glaucoma.To evaluate association between visual field loss ONH transient IOP elevations.In this observational study, 91 Chinese patients (23 with primary open-angle glaucoma [POAG], 45 angle-closure glaucoma, 23 without glaucoma) were recruited from September 3, 2014, through February 2, 2017. Optical coherence tomography scans...
To compare the differences in intraoperative complications rates by number of resident-performed sequential phacoemulsification surgeries.Preoperative and postoperative ophthalmological examination records data 180 eyes 140 patients who underwent cataract surgery two residents between November 2009 February 2012 were analyzed retrospectively. The separated into 3 groups based on operations performed: Group A (first 1-60 eyes), group B (61-120 eyes) C (last 121-180 eyes). direct supervisor...
The aim of this study was to present a novel technique avoid the open-sky condition in pediatric and adult penetrating keratoplasty (PK).Seventy-two eyes 65 infants children 44 patients were operated on using technique. After trephining recipient cornea up depth 50% 70%, anterior chamber entered at 1 point. Then, only 2 clock hour segment button incised, sutured rim with single tight suture. procedure repeated until entire excised resutured. donor corneal rim. sutures between then cut off,...
