Hyperbaric oxygen treatment results in a group of Turkish central retinal artery occlusion patients with a combined presence of thrombophilic mutations.

Background: Central retinal artery occlusion (CRAO) is a rare ocular-ischemic syndrome causing irreversible blindness. Its pathophysiology has not been clarified, and no targeted therapies are available yet. Hyperbaric oxygen (HBO2) therapy is already an approved therapy for CRAO and has been shown to improve the visual acuity of CRAO patients safely.

The safety and effectiveness of 0.16 mg bevacizumab plus or minus additional laser photocoagulation in the treatment of retinopathy of prematurity.

Purpose: Retinopathy of prematurity (ROP) is the leading cause of preventable blindness in premature infants. Antivascular endothelial growth factor (anti-VEGF) therapy has been used increasingly in treatment as a pharmacological alternative to laser therapy. In this study, we evaluate the results of low-dose anti-VEGF treatments.

Effects of Common Thrombophilia Factor Mutations in Central Retinal Vein Occlusion.

Objectives: Central retinal vein occlusion (CRVO) is a severe eye disease that impairs vision. Although numerous systemic conditions have been reported to be a contributor, its exact pathophysiology has not yet been resolved. The purpose of this study was to study the role of some common thrombophilic polymorphisms in CRVO patients.

Effect of hyperbaric oxygen treatment in central retinal artery occlusion.

Background: Central retinal artery occlusion (CRAO) is a rare and serious ophthalmologic emergency with a bad prognosis. Hyperbaric oxygen (HBO2) treatment has been reported to improve visual acuity of CRAO patients. However, there are unknown variables for HBO2 treatment such as initiation period, number of sessions and efficacy.

Comparison of the Effect of Intravitreal Dexamethasone Implant in Vitrectomized and Nonvitrectomized Eyes for the Treatment of Diabetic Macular Edema.

Purpose: To compare the effectiveness of sustained-release dexamethasone (DEX) intravitreal implant in nonvitrectomized eyes and vitrectomized eyes with diabetic macular edema (DME).

Methods: A retrospective review of the medical records of 40 eyes of 30 consecutive patients with diabetic macular edema who underwent intravitreal DEX implant injection. Patients were divided into 2 subgroups: 31 eyes that were nonvitrectomized (group 1) and 9 eyes that had previously undergone standard pars plana vitrectomy (group 2).

Iris-claw intraocular lens implantation in children with ectopia lentis.

Purpose:: Artisan iris-claw lens implantation (AICLI) is a surgical technique for treating ectopia lentis. We aimed to compare visual outcomes and possible long-term complications of AICLI surgery in pediatric patients with ectopia lentis with or without a diagnosable hereditary disease.

Methods:: Seventeen children with non-traumatic ectopia lentis were retros pectively classified into two groups: group 1 included children with a diagnosable hereditary disease (11 patients, 65%), and group 2 included children without any definable hereditary disease (six patients, 35%).

Corneal endothelial cell density in healthy Caucasian population.

Aim: To reveal the changes of corneal endothelial characteristics with aging among Caucasian population.

Methods: Non-contact specular microscopy was performed in 564 eyes of 282 healthy Caucasian Turkish patients. Endothelial cell density (MCD), mean cell area (MCA), coefficient of variation (CV) in cell size, percentage of hexagonal cells, and central corneal thickness (CCT) were measured.

Comparison of central corneal thickness estimated by an ultrasonic pachymeter and non-contact specular microscopy.

Purpose:: To compare central corneal thickness (CCT) measurements of healthy individuals obtained with ultrasonic pachymetry (UP) and non-contact specular microscopy (NCSM).

Method:: In total, 148 eyes of 74 subjects with no ocular or systemic diseases were included in the study. Central corneal thickness measurements of all patients performed with UP and NCCM were compared.

Relationship among Corneal Biomechanics, Anterior Segment Parameters, and Geometric Corneal Parameters.

. To investigate the relationship between corneal biomechanical parameters, anterior segment parameters, and geometric corneal parameters in a healthy Caucasian group. .

VITREORETINAL SURGERY FOR PATIENTS WITH SEVERE EXUDATIVE AND PROLIFERATIVE MANIFESTATIONS OF RETINAL CAPILLARY HEMANGIOBLASTOMA BECAUSE OF VON HIPPEL-LINDAU DISEASE.

Purpose: The evaluation of long-term results of vitreoretinal surgery and retinal capillary hemangioblastoma (RCH) resection in patients with complicated retinal detachment (RD) secondary to RCHs.

Methods: Twelve eyes of 12 patients were operated on with vitreoretinal surgery, including occlusion of afferent and efferent feeder vessels with endodiathermy and endolaser photocoagulation, and subsequent resection of RCHs. The long-term anatomical and visual outcomes were retrospectively evaluated.

An Important Cause of Blindness in Children: Open Globe Injuries.

Objective. Our aim was to present and evaluate the predictive factors of visual impairment and blindness according to WHO criteria in pediatric open globe injuries. Methods.

Sociodemographic status of severely disabled and visually impaired elderly people in Turkey.

Purpose: To identify the prevalence of ophthalmologic diseases in elderly patients who had been classified as severely disabled and to identify the ophthalmologic conditions leading to visual impairment and blindness.

Methods: The medical records of 2806 patients who had applied to the Health Board of the Erzurum Region Training and Research Hospital between January 2011 and December 2012 were reviewed. One hundred ninety-nine patients aged >64 years who were classified as severely disabled with disability rates of over 50%, and who were unable to care for themselves or to move and/or communicate without help were included in the study.

Unilateral uveitis, cataract and retinal detachment following low-voltage electrical injury.

A 39-year-old woman presented with a gradual worsening of vision in the right eye 1 month after a low-voltage household electrical injury. A slit-lamp examination showed non-granulomatous anterior uveitis with nuclear cataract and an ultrasound examination also showed total retinal detachment. In this letter, we present a rare complication of electrical injury demonstrated as unilateral uveitis, cataract and retinal detachment in a 39-year-old woman.

Correlation of spectral domain optical coherence tomography findings and visual acuity in central serous chorioretinopathy.

Purpose: To investigate the correlation between spectral domain optical coherence tomography findings and best-corrected visual acuity (BCVA) in patients with central serous chorioretinopathy (CSC) and to determine the visual prognostic factors.

Methods: We retrospectively studied 56 eyes of 49 patients who had the diagnosis of CSC. Patients were categorized into subgroups depending on symptoms and clinical findings.
