Symptomatic excyclotorsion is an important clinical problem, especially in acquired superior oblique muscle palsy. Excyclotorsion can disrupt the fusion and cause torsional diplopia. Harada-Ito surgery (HI) is a widely used method for treating excyclotorsions. This method relieves the torsional diplopia by increasing the effect of the incyclotorsion. In this study, we aimed to report the clinical features of patients with torsional diplopia due to acquired trochlear nerve palsy and the results of HI surgery in these patients...

Pachychoroid neovasculopathy (PNV) is a form of type 1 neovascularization characterized by dilated choroidal vessels in areas of increased choroidal thickness. In this article, we describe a patient diagnosed with PNV. A 50-year-old male with a 2-month history of blurred vision was referred to our clinic. His best corrected visual acuity was 20/100 in both eyes. Retinal pigment epithelium alterations, which were more prominent in fundus autofluorescence, were detected in both eyes on dilated fundus examination...

Neuroretinitis characterized by optic disc edema and star-like exudates in the macula was detected in a patient who presented with sudden unilateral painless vision loss and had a history of raw meat consumption. The patient tested seropositive for Toxocara . Combination therapy with steroid and albendazole resulted in an increase in visual acuity and complete resolution of clinical signs.

A 24-year-old female presented with bilateral vision loss following attempted suicide with pregabalin. Her best-corrected visual acuity (BCVA) was 20/40 in the right eye and 20/50 in the left eye. The bilateral visual disturbance was associated with serous macular detachment. Fundus examination of both eyes showed foveal serous retinal detachment, which was confirmed by optical coherence tomography. Topical nepafenac 0.1% eye drops were started as single drop every 8 hours for 4 weeks. One month later, the serous macular detachment had regressed and BCVA increased to 20/20 in both eyes...

We report a male premature baby who was born at 24 weeks gestation weighing 600 grams. There was bilateral stage 2, zone 2 retinopathy of prematurity (ROP) without plus disease at 38 weeks postmenstrual age. Ultra-wide-field Optomap images obtained 1 week later showed no change in ROP stage. At 40 weeks postmenstrual age, stage 3, zone 2 ROP was detected using binocular indirect ophthalmoscopy and documented using Optos. Minor tortuosity and dilation of vessels was interpreted as pre-plus disease. One week later, at 41 weeks postmenstrual age, Optomap images identified progressive extraretinal fibroproliferation in the nasal quadrant...

Materials and Methods: Multicenter, retrospective, interventional, non-comparative study. The records of nAMD patients treated with an anti-VEGF agent on a pro re nata treatment regimen basis between January 2013 and December 2015 were reviewed. The patients who completed a follow-up period of 12 months were included...

Objectives: To evaluate anterior segment parameters measured by dual Scheimpflug corneal topography in pseudoexfoliative glaucoma (PEXG), primary angle-closure glaucoma (PACG), and healthy eyes. Materials and Methods: One hundred forty-three eyes of 86 patients were included in this study. Forty-seven eyes of 38 patients with PEXG, 30 eyes of 15 patients with PACG, and 66 eyes of 33 healthy subjects were evaluated. Patients who underwent previous ophthalmic surgery and contact lens wearers were excluded...

Objectives: To investigate whether unfolding time of Descemet membrane (DM) graft rolls changes at various fluid temperatures. Materials and Methods: The study was prospective, ex vivo , and experimental. The study was conducted at the tertiary center for corneal disease in Adana Numune Training and Research Hospital between June 2014 and June 2015. DMs were divided into 4 categories according to baseline roll tightness and these were distributed among 4 different groups using 4 different balanced salt solution (BSS) temperatures (8, 16, 23, and 36 °C)...

Objectives: To investigate the three single nucleotide polymorphisms (SNPs) (rs3825942, rs1048661, and rs2165241) of the LOXL1 gene in pseudoexfoliation syndrome (XFS) and pseudoexfoliation glucoma (XFG) in the Turkish population. Materials and Methods: DNA was obtained from blood samples of 48 XFS, 58 XFG, and 171 control subjects. Three LOXL1 SNPs (rs3825942, rs1048661, rs2165241) were investigated with real time PCR, a probe-based genotyping method, and melting curve analysis...

Familial exudative vitreoretinopathy (FEVR) is a rare inherited disorder of retinal angiogenesis. A 49-year-old male patient was referred to our clinic for retinal vascular occlusion. His history, clinical findings, and fundus fluorescein angiography findings were evaluated. Family members were called and eye examinations were performed. Our patient was not born preterm and he reported decreased visual acuity after a traffic accident during childhood. He had laser treatment when he was 12 years old and again 1 month before our examination...

Choroidal neovascular membrane (CNV) is a very rare complication in patients with sympathetic ophthalmia. We hereby report a 38-year-old man who developed a type 2 CNV in his only seeing (left) eye while under systemic steroid treatment. Systemic therapy was revised and a total of 5 intravitreal aflibercept injections (2 mg each) were administered over a period of 8 months. Good anatomic and functional outcome was noted at the last visit. Anti-vascular endothelial growth factor injection may be an important adjunct to systemic therapy in eyes with with sympathetic ophthalmia-associated CNV...

In this case report, we presented a patient with visual deterioration as a result of papillophlebitis in the right eye who was later diagnosed with Guillain-Barré syndrome (GBS). Upon systemic and laboratory work-up to determine the etiology of papillophlebitis, the diagnosis of GBS was made and treatment was initiated immediately. The ocular and systemic symptoms resolved quickly after starting intravenous immunoglobulin therapy. We present this case to emphasize the importance of etiological diagnosis in papillophlebitis and the unusual presentation of GBS...

In this study, we present a case of bilateral optic neuropathy and macular ischemia in the right eye associated with neurosarcoidosis. A 26-year-old woman presented to our clinic with complaints of bilateral blurred vision. Bilateral granulomatous anterior uveitis, vitritis, optic neuropathy, and macular ischemia were detected in the right eye in slit-lamp examination. She also reported complaints of fever, weakness, sweating, arthralgia, and headache for 2 months. She was referred to the pulmonary diseases unit of our hospital due to hilar lymphadenopathy seen in her chest x-ray, and biopsies were taken for diagnostic purposes...

Optical coherence tomography angiography (OCTA) comprises different OCT-based technologies developed for non-invasive assessment and measurement of optic nerve head and retinal perfusion. Currently the most clinically established approach is based on the split spectrum amplitude decorrelation algorithm, which detects moving red blood cells and eliminates all other information. The two main clinical fields in which OCTA offers clinically useful information are investigation of the macular retina (e.g. in macular degeneration and diabetic macular disease) and glaucoma...

Objectives: This paper presents the design and construction of a viable pupillometer system and demonstrates its merits with extensive validation tests. Materials and Methods: A web camera was modified by removing its infrared filter and mounted on a chin rest. Light emitting diodes (LEDs) operating at infrared and visible spectra were integrated to provide background and light stimulus, respectively. The LEDs were controlled by a microprocessor board. Stimulation was presented using a periodic paradigm with variable period and duty cycle...

Objectives: To determine interindividual variability in the angle between the anatomic axis connecting the fovea and optic disc center and the horizontal meridian using spectral domain optical coherence tomography (OCT). Materials and Methods: A total of 260 eyes of 133 subjects (81 women, 52 men) with glaucoma or suspected glaucoma were included in the study retrospectively. Fovea-disc angle (FoDi angle) measurements, determined as the angle between the horizontal meridian passing through the Bruch's membrane opening (BMO) center and the line connecting the fovea and BMO center, were recorded from spectral domain-OCT scans performed by the same investigator...
