A predictive score for retinopathy of prematurity by using clinical risk factors and serum insulin-like growth factor-1 levels.

Aim: To detect the impact of insulin-like growth factor-1 (IGF-1) and other risk factors for the early prediction of retinopathy of prematurity (ROP) and to establish a scoring system for ROP prediction by using clinical criteria and serum IGF-1 levels.

Methods: The study was conducted with 127 preterm infants. IGF-1 levels in the 1 day of life, 1, 2, 3 and 4 week of life was analyzed.

Background: The aim of this study was to evaluate the color-changing effect and adverse effects after Nd: YAG laser application on the iris surface of rabbit eyes.

Material/methods: The study was performed on right eyes of 12 pigmented rabbits. A laser device that produces frequency doubled 532 nm wavelength Nd: YAG laser with 900 μm spot diameter was used.

Influence of hyperbaric oxygen therapy on central corneal thickness.

Background/aims: Hyperbaric oxygen (HBO) therapy is used in the treatment of several disorders. Little is known about the effects of HBO treatment on corneal thickness. The aim of this study was to investigate the effect of HBO treatment on central corneal thickness.

Selective laser trabeculoplasty induced changes in the thickness of ciliary body and iris evaluated by ultrasound biomicroscopy.

Background: Selective laser trabeculoplasty (SLT) is widely used for the treatment of glaucoma. The main target tissue of this treatment modality is trabecular meshwork. We aimed to detect the SLT-induced changes in the thickness of ciliary body (CBT) and iris (IT), quantitatively.

Autofluorescence findings in Vogt-Koyanagi-Harada disease.

Purpose: To report shortwave autofluorescence (SW-AF) and near infrared autofluorescence (NIR-AF) findings in a case of Vogt-Koyanagi-Harada (VKH) disease.

Methods: A 22-year-old man presented with a 2-week history of headache, moderate hearing loss, discolored hair, and bilateral gradually decreased vision (20/800 bilaterally). Ophthalmologic examinations revealed bilateral granulomatous anterior uveitis and multiple patchy bullous retinal detachments.

Carbon monoxide-induced cortical visual loss: treatment with hyperbaric oxygen four years later.

Objective: We present a patient who developed visual loss after carbon monoxide (CO) poisoning and was treated with hyperbaric oxygen.

Clinical Presentation And Intervention: A 21-year-old woman poisoned with CO (with coma lasting 4 h and carboxyhemoglobin level 46%) developed seizures and cortical blindness 3 days after poisoning. Four years later, her visual acuity was 0.

Validation of the ocular trauma score for intraocular foreign bodies in deadly weapon-related open-globe injuries.

Background And Objective: To evaluate the prognostic value of the Ocular Trauma Score (OTS) in cases of deadly weapon-related open-globe injuries with intraocular foreign bodies.

Patients And Methods: A retrospective, interventional case series included 20 eyes of 20 patients who had deadly weapon-related open-globe injuries with intraocular foreign bodies. The OTS was calculated for each patient by adding the determined numbers of OTS variables at presentation (initial visual acuity, rupture, endophthalmitis, perforating injury, retinal detachment, and afferent pupillary defect).

Cytokine profile in Behçet uveitis.

Objectives: Investigate the role of cytokines in Behçet uveitis.

Background: Cytokines may take part in this pathogenetic mechanism. Elevated and/or altered levels of specific cytokines have been found in patients with Behçet's disease in many studies.

Photodynamic therapy for posterior capsule neovascularization.

We report a 71-year-old man with posterior capsule opacification with severe neovascularization who was treated with photodynamic therapy and neodymium:YAG capsulotomy. Treatment was performed using a diode laser at 692 nm, a light dose of 50 J/cm(2), and 6 mg/m(2) body surface area verteporfin. The initial visual acuity was hand motions; 6 months after therapy, the visual acuity was stable at 20/200.

Intraocular pressure at a simulated altitude of 9000 m with and without 100% oxygen.

Introduction: Exposure to high altitude may affect intraocular pressure (lOP). This study aimed to determine how IOP was altered by two different inspired oxygen tensions at altitude.

Methods: There were 34 healthy male pilots, ages 26-39 yr (mean 31.

The efficacy of hyperbaric oxygen for the treatment of experimental uveitis induced in rabbits.

Objective: The aim of the present study was to examine the efficacy of hyperbaric oxygen (HBO) therapy in the treatment of experimental uveitis induced in rabbits. It was hypothesized that HBO therapy improves the regression of experimental uveitis induced in rabbits.

Research Design And Methods: An experimental animal study was conducted on 48 rabbits (48 right eyes of these rabbits) to evaluate the effects of HBO therapy on endotoxin-induced acute anterior uveitis in rabbits.

Management of retinal detachment due to closed globe injury by pars plana vitrectomy with and without scleral buckling.

Background And Purpose: To investigate the effect of circumferential scleral buckling on the prognosis for patients undergoing pars plana vitrectomy and lensectomy for severe closed globe injury.

Methods: A total of 33 cases in which pars plana vitrectomy and lensectomy were performed after severe closed globe injury between January 1990 and January 2003 were studied retrospectively. All patients had zone III contusion type injury according to The Ocular Trauma Classification Group criteria.

Results of pars plana vitrectomy in closed-globe injuries.

Background And Objective: To assess surgical and visual outcomes with pars plana vitrectomy (PPV) in closed-globe injuries resulting in anterior and posterior segment pathologies and evaluate the factors influencing the prognosis.

Patients And Methods: Retrospective observational study. Forty-seven eyes of 47 consecutive patients who underwent PPV because of closed-globe injury between January 1992 and August 2003 were reviewed.

Histopathologic changes in the lacrimal sac of dacryocystorhinostomy patients with and without silicone intubation.

Purpose: To evaluate the histopathologic impact of dacryocystorhinostomy (DCR) and silicone intubation on the lacrimal sac.

Methods: Biopsy materials were taken from the sac wall and fixed (primary biopsy) in 224 patients undergoing DCR between 1995 and 2003 in our institution. A total of 23 patients underwent a second operation as the result of restenosis, and a secondary biopsy specimen was taken from the sac wall.

Methods: Two female patients developed visual deterioration after carbon monoxide (CO) poisoning and were treated with hyperbaric oxygen therapy (HBO). Clinical examination, including visual acuity assessment, visual field examination and visual evoked potentials (VEPs) before and after the HBO therapy were performed.
