Purpose: To report the effectiveness of single-stage two-muscle surgery of 7-11 mm in patients with large-angle exotropia.

Methods: A retrospective analysis of 34 patients with a large-angle comitant exodeviation was conducted. Patients were classified as severe (group 1) if the average deviation was ≥ 50 prism diopters (PD) and moderate (group 2) if their deviation ranged from 30 to 49 PD.

Evaluation of ocular biometric parameters in keratoconic eyes relative to healthy myopic eyes.

Objective: To assess the biometric features of keratoconic eyes using the Lenstar LS900 and Pentacam systems relative to healthy myopic eyes.

Materials And Methods: Seventy-three eyes of keratoconic subjects and 83 eyes of control subjects were enrolled. To evaluate the reproducibility of the Lenstar and Pentacam devices' measurements, keratometric readings [in flattest meridian (Kf), in steepest meridian (Ks), and mean (Km)], central corneal thickness (CCT), and anterior chamber depth (ACD) were obtained using both systems.

Effect of obstructive sleep apnoea syndrome and continuous positive airway pressure treatment on choroidal structure.

Objectives: To evaluate the effect of obstructive sleep apnoea syndrome (OSAS) and continuous positive airway pressure (CPAP) therapy on choroidal structural changes and choroidal vascularity index (CVI) in patients with OSAS.

Methods: Choroidal structural changes in patients with OSAS immediately after diagnosis and 12 months after CPAP treatment were evaluated and compared with healthy controls. The choroidal images on enhanced depth imaging optical coherence tomography (EDI-OCT) were binarized into luminal area (LA) and stromal area (SA) using the ImageJ software.

Comparison of half-dose versus half-fluence versus standard photodynamic therapy in chronic central serous chorioretinopathy.

Purpose: To compare the efficacy and safety of half-dose vs. half-fluence vs. standard photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC).

Combined treatment of transluminal Nd:YAG laser embolysis and hyperbaric oxygen for branch retinal artery occlusion.

To describe the clinical efficiency of transluminal Nd:YAG laser embolysis (TYE) and hyperbaric oxygen (HBO) as an off-label combined treatment for branch retinal artery occlusion (BRAO) with visible emboli. A 77-year-old woman had a history of seeing a "shadow" in the lower visual field of the left eye for three days. Platelet-fibrin embolus at the arterial bifurcation was disintegrated by TYE technique and the patient was referred to HBO treatment for 20 sessions.

Effectiveness of Intravitreal Ranibizumab in Nonvitrectomized and Vitrectomized Eyes with Diabetic Macular Edema: A Two-Year Retrospective Analysis.

The aim of this study was to compare the effectiveness of intravitreal ranibizumab (IVR) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy. The medical records of 28 eyes (11 vitrectomized and 17 nonvitrectomized) of 28 patients (mean age, 59.0 ± 9.

Structural assessment of the optic nerve in patients with obstructive sleep apnea syndrome: Case-control study.

Objective: Obstructive sleep apnea syndrome has been identified as a possible risk factor for optic nerve pathology such as glaucoma, nonarteritic ischemic optic neuropathy, and optic disk edema. Accordingly, we aimed to evaluate structural changes of the apparently normal optic nerve in obstructive sleep apnea syndrome patients with effects of its severity.

Materials And Methods: In this prospective case-control study, 47 eyes of 47 obstructive sleep apnea syndrome patients diagnosed with polysomnography and 40 eyes of 40 healthy subjects were included.

Ex-PRESS implantation for different types of glaucoma.

Aim: To evaluate the clinical results, efficacy and safety of Ex-PRESS P200 glaucoma shunt implant in different types of medically uncontrolled glaucoma.

Methods: The study included 31 eyes of 31 patients that were unresponsive to medical antiglaucomatous therapy in whom Ex-PRESS P200 glaucoma shunt implantation was performed. The demographic characteristics of the patients, type of glaucoma, complete ocular examination results, number of antiglaucomatous drugs before and after surgery, early and late complications of surgery, additional surgical and nonsurgical medical interventions, and success rates were investigated from the patients' files, retrospectively.

Acquired perforating collagenosis associated with ranibizumab injection and succesfully switched to aflibercept.

To report a case of acquired reactive perforating collagenosis (ARPC) triggered by an intravitreal ranibizumab injection that was successfully treated by switching to aflibercept (AFL). A 73-year-old Caucasian man with an occult choroidal neovascular membrane in the right eye received three-monthly intravitreal ranibizumab injections. Two weeks after the second ranibizumab injection, he complained about a generalized, excessively pruriginous eruption that was further exacerbated by the third injection.

Effect of Therapy on Choroidal Thickness in Patients With Obstructive Sleep Apnea Syndrome.

Background And Objective: To evaluate effect of continuous positive airway pressure (CPAP) therapy on choroidal thickness in patients with obstructive sleep apnea syndrome (OSAS).

Patients And Methods: Thirty distinct eyes of 30 patients with OSAS were evaluated right before and 12 months after CPAP treatment in this prospective observational study. Choroidal thickness was measured at the fovea and with periodic intervals of 500 µm from the foveal center in both temporal and nasal directions using spectral-domain optical coherence tomography in enhanced depth imaging mode.

The Efficacy and Safety of Intravitreal Dexamethasone Implant for the Treatment of Macular Edema Related to Retinal Vein Occlusion: Real-life Data and Prognostic Factors in a Turkish Population.

Objectives: To evaluate the efficacy and safety of dexamethasone (DEX) implants as mono or combination therapy for macular edema in retinal vein occlusion (RVO) with real-life conditions, and to detect factors that influence final visual acuity.

Materials And Methods: Twenty-five eyes with macular edema secondary to RVO underwent assessments for central macular thickness (CMT), best-corrected visual acuity (BCVA), adverse events, and also morphologic changes in optical coherence tomography at an interval of 4-8 weeks after at least one DEX implant.

Results: Seventeen eyes with branch RVO and 8 eyes with central RVO were eligible for the study.

Reproducibility and repeatability of central corneal thickness measurement in healthy eyes using four different optical devices.

Aim: The aim of the study is to compare the measurements of central corneal thickness (CCT) performed by two examiners with four different methods at different times inter- and intra-individually.

Methods: Thirty healthy people were included in the study. In these measurements, an optical low-coherence reflectometry (OLCR), an optic coherence tomography (OCT), a specular microscopy (SM), and a corneal topography (CT) were used.
