Purpose: To investigate the frequency and type of artifacts on OCT angiography (OCTA) images and the relationship with clinical features in eyes with diabetic macular edema (DME).
Design: Retrospective, cross-sectional comparative study.
Subjects: One hundred ninety-two eyes of 140 patients with DME were included.
Purpose: To evaluate using optical coherence tomography angiography the macular and optic nerve head blood flow in pediatric patients with epilepsy treated with levetiracetam for at least 12 months.
Methods: This study included 33 pediatric patients with epilepsy and 30 sex- and age-matched healthy volunteer children were included in the study. Optical coherence tomography angiography was used to evaluate the optic nerve head and macular perfusion changes.
The aim of this prospective, controlled, non-randomized study was the comparison of the retinal microvascular parameters of obese and nonobese adults. 184 eyes of 92 subjects were separated to 3 groups. 68 eyes were in the normal weight group, with a body mass index between 18.

Materials And Methods: Thirty-seven eyes with cystoid macular edema who received IVR or IVD and followed up for at least 12 months were included in this study. The patients were divided into three Groups according to intravitreal treatments.
Purpose: To evaluate the effect of preoperative Alprazolam on complications of phacoemulsification cataract surgery, duration of surgery and early reoperation rate.
Methods: Records of 1026 eyes of 1026 consecutive patients underwent phacoemulsification with topical and intracameral anesthesia between 2016 and 2020 years were retrospectively reviewed. Patients were divided into two groups, with or without using Alprazolam before surgery.
Objectives: The purpose of this study was to identify the sensitivity and specificity of optical coherence tomography angiography (OCTA) parameters for the presence of neovascularization elsewhere (NVE) and to investigate the relationship between ischemic areas.
Methods: This study included 59 eyes with non-proliferative diabetic retinopathy (NPDR) and 36 eyes with proliferative diabetic retinopathy (PDR). The foveal avascular zone (FAZ), vessel density (VD) for the superficial and the deep capillary plexus (DCP), choriocapillaris flow area (CCP), and non-perfusion area (unit²) were recorded.
Purpose: To assess the choroidal vascularity index (CVI) after subthreshold laser treatment in patients with central serous chorioretinopathy (CSC).
Method: A total of 32 eyes with CSC were included in this study. In group 1, 14 eyes with persistent CSC were treated with the PASCAL (Endpoint Management Software) at 577-nm wavelength and in group 2, 18 eyes without treatment.
A 61-year-old woman presented to our clinic with complaints of decreased visual acuity, pain, and redness in her left eye. Best corrected visual acuity (BCVA) was 20/20 in the right eye and counting fingers at 3 meters in the left eye. On slit-lamp examination, 1+ cells were detected in the anterior chamber.
View Article and Find Full Text PDFObjectives: To assess multifocal electroretinogram (mf-ERG) values in patients with diabetic macular edema (DME) who were treated with intravitreal ranibizumab (IVR).
Methods: Thirty eyes of patients with DME, who underwent three consecutive monthly injections of IVR and as required thereafter, were evaluated. Best corrected visual acuity (BCVA) (log MAR), optical coherence tomography (OCT) features [diameters of cyst and subretinal fluid, hyperreflective dots (HRDs)], and mf-ERG were evaluated at baseline, 1 month, and 6 months throughout the follow-up period.
Purpose: To compare the macular microvasculature differences in cases with idiopathic macular hole (MH) after vitrectomy when using internal limiting membrane (ILM) removal or temporal inverted ILM flap technique (IFT).
Method: A total of 34 patients were included, of whom 20 were treated vitrectomy with ILM removal (group 1), and 14 were treated with IFT (group 2). The OCTA (RTVue; Optovue, Fremont, CA) parameters, including foveal avascular zone (FAZ), vessel density (VD) ratios in superficial capillary plexus (SCP), and deep capillary plexus (DCP) were evaluated at baseline and 6 months follow-up.
Objective: The aim of this study was to evaluate the perifoveal and peripapillary microvascular structure in patients with Behçet's disease (BD) without clinically ocular involvement.
Methods: Fifty-six eyes of 28 patients with Behçet's disease without clinically ocular involvement and 50 age-matched healthy eyes were included in this prospective study. Vessel densities (VD) of macula and optic nerve head, foveal avascular zone (FAZ), choroid capillary plexus (CCP) flow area, perifoveal capillary nonperfusion, capillary dilatation and/or telangiectasia and perifoveal capillary arcade disruption were analyzed with optical coherence tomography angiography (OCTA).
Purpose: To evaluate the macular microvascularity with optical coherence tomography angiography (OCTA) in rhegmatogenous retinal detachment (RRD) which were successfully treated with pneumatic retinopexy (PR).
Methods: Thirty eyes of thirty patients who were treated with PR (12 eyes with macula-off RRD and 18 eyes with macula-on RRD) were included in this prospective study. OCTA was used to evaluate the macular perfusion changes postoperatively at 1 and 3 months.
Purpose: To evaluate alterations in corneal biomechanical properties before and 6 months after conventional trabeculectomy (TRAB) and Ahmed glaucoma valve (AGV) implantation.
Methods: Thirty-nine eyes of 39 patients were evaluated retrospectively. Complete ophthalmological examinations including evaluation of corneal biomechanical properties using the Ocular Response Analyzer were performed before and after 6 months postoperatively.
Purpose: To perform a long-term comparison of the quantitative efficacy of internal and external browpexy in combination with upper-lid blepharoplasty based on lateral and central eyebrow positions.
Methods: This retrospective study evaluated internal and external browpexy with upper-lid blepharoplasty surgeries that were performed during the period between January 2012 and December 2017 in the oculoplastic surgery department of our hospital. Patients who had undergone periorbital and forehead surgery, who had ophthalmologic or neurological diseases, and who were Botox users were not included in the study.
Objectives: To report the results obtained from glaucoma drainage device (GDD) implantation in patients with aniridia-related glaucoma and to review the literature.
Materials And Methods: We retrospectively reviewed 6 patients who underwent GDD implantation for glaucoma secondary to congenital aniridia between April 2001 and February 2015. Data on age at surgery, gender, laterality, surgeries before GDD implantation, GDD model, concomitant ocular disorders, visual acuity, and intraocular pressure (IOP) values before and at 1 and 12 months after GDD implantation, medications, follow-up period, findings during last visit, complications, and course of disease were collected.
Objectives: In this study, we compared the surgical outcomes of penetrating keratoplasty using domestic and imported donor corneas.
Materials And Methods: We retrospectively evaluated 200 eyes and 200 consecutive patients who underwent penetrating keratoplasty by using domestic and imported donor corneas between January 2013 and December 2013. The donor characteristics, preoperative clinical features, and clinical outcomes at 6, 12, 24, and 36 months were assessed.
