To assess the efficacy of quantitative analysis optic nerve head and peripapillary retinal fiber layer (RNFL) with spectral-domain optical coherence tomography (SD-OCT) in differentiating disc edema (ODE) from drusen (ONHD).Prospective clinical study. Twenty-five eyes 25 ODE patients (group 1), ONHD 2), healthy subjects were included. The thickness RNFL, subretinal hyporeflective space (SHYPS), area SHYPS, horizontal length head, angle between temporal RNFL (α-angle) evaluated SD-OCT.The...
To investigate the incidence, contributing factors, management, and long-term outcomes of endophthalmitis following intravitreal injections performed in our clinic. This retrospective study included all patients who received bevacizumab, aflibercept, ranibizumab, or dexamethasone between 2019 2024 at four retina clinics Ankara Bilkent City Hospital. Demographic characteristics patients, visual acuity, injection etiology, comorbidities, treatments applied were recorded. Patients antibiotic...
Purpose: To evaluate the presence of dry eye and primary Sjögren syndrome (SS) in patients with migraine.Methods: In total, 46 eyes migraine (group 1) 50 healthy subjects 2) were included this study. Detailed ophthalmologic, neurologic rheumatologic examination performed on all participants. Ocular surface disease index questionnaire, tear function tests, visual analog scale for pain, serologic analysis also performed.Results: Dry symptoms findings significantly higher more severe group 1...
Objective: To determine the significance of presence ectopic inner foveal layer (EIFL) in cases with idiopathic epiretinal membrane (iERM). Material and Methods: Optical coherence tomography (OCT) images 140 iERM at initial examination were evaluated. According to their EIFL staging,the divided into four stages. For all cases, best corrected visual acuity (BCVA) obtained from OCT measurements, including central thickness (CFT), retinal (CRT), maximum (MRT), nuclear (INL) thickness, outer...
Objectives: To evaluate the clinical results of a new trifocal intraocular lens (IOL) with sinusoidal design by comparing traditional IOL.Materials and Methods: A total 79 patients undergoing uneventful microincisional cataract surgery bilateral implantation one two types IOLs, Acriva Trinova IOL (VSY) or Acrysof IQ PanOptix (Alcon), were enrolled in this prospective study.Visual refractive outcomes, contrast sensitivity (CS), defocus curve assessed at 3 months after surgery.Patient...
Objectives:We aimed to demonstrate the 5-year visual, topographic, and aberrometry long-term results of standard collagen crosslinking (CCL) treatment in keratoconus patients. Materials Methods:The files topographic measurements patients who underwent CCL for progressive were retrospectively reviewed.Uncorrected visual acuity (UCVA), best corrected (BCVA), refraction values, values evaluated.Results: Thirty-seven eyes 27 included study.The female male ratio was 15 (56%)/12 (44%) mean age...

To determine the effects of first-dose administration Sinovac vaccine on retina, choroid, and optic disc in healthy participants.
To evaluate the effects of three different silicone hydrogel contact lenses (SHCL), (balafilcon A, senofilcon and comfilcon A) on tear function tests, corneal thickness, ocular surface cytology in first time lens users.In this prospective study, 120 eyes 60 subjects were evaluated. Balafilcon A users designated as group 1, 2, 3. In all cases, before after 6 months wear, disease index score (OSDI), breakup (TBUT), Schirmer 1 test, central thickness (CCT), epithelium (CCET), conjunctival...
To evaluate the intraocular pressure (IOP) measurements by Icare rebound tonometer over a contact lens in comparison with Goldmann applanation tonometry (GAT).Fifty patients using were included this study. One of eyes was selected randomly and their IOP measured without (RTCL, RT respectively) GAT, as well central corneal thickness (CCT) optical pachymeter. The results both methods compared correlation analysis, general linear method repeated measure Bland-Altman analysis.Mean values RTCL,...
We aimed to compare the clinical results and topographic data of new generation hybrid contact lens (HCL) rigid gas-permeable (RGPCL) in patients with moderate advanced keratoconus.In this prospective study, HCL users comprised group 1 RGPCL 2. Snellen uncorrected visual acuity (UCVA), best corrected (BCVA), lens-corrected (LCVA); manifest spherical-cylindrical values; corneal topography measurements (flat keratometry [K1], vertical [K2], mean K, maximum K [Kmax], central thickness [CCT],...
Purpose: To describe the technique of modified girth-hitch suture for one side transscleral fixation to rescue a single haptic dislocation. Methods: In this surgical report, dislocated scleral fixated posterior chamber IOL were secured sclera using 10-0 polypropylene looped around haptic. Three types in study (4 case 1-piece PMMA IOL, 1 3-piece acrylic with loop and foldable two-plate design). Results: Six patients, who had subluxation scleral-fixated posterior-chamber due single-knot...
It is known that the incidence of lung cancer increasing rapidly in both men and women. While no ocular findings may be observed early stage, involvement advanced stage. The choroid most common site intraocular metastasis adults due to its rich vascularisation. In this report, a 52-year-old woman was referred our clinic because retinal detachment detected an external center with complaints flashes light left eye 3 months ago decreased vision for past week. learned she diagnosed stage (stage...
