Choroidal and macular thickness changes in type 1 diabetes mellitus patients without diabetic retinopathy.

Objectives: To explore choroidal thickness (ChT) and retinal thickness (RT) changes in patients with type 1 diabetes mellitus (DM).

Methods: Sixty patients with Type 1 DM and 60 age- and sex-matched healthy controls were included in this prospective case-control clinical study. All patients underwent a complete ophthalmological examination.

Delayed visual loss due to radiation retinopathy.

Radiation retinopathy remains a devastating cause of visual morbidity in patients undergoing radiation for globe, orbit, and head and neck malignancies. A 65-year-old female was admitted with the complaint of low vision in the right eye for two months. Best corrected visual acuity was 20/32 in the right eye and 20/25 in the left eye.

Retinal structural changes in systemic arterial hypertension: an OCT study.

Purpose: To assess retinal nerve fiber layer (RNFL), ganglion cell complex (GCC), and macular thickness changes in young adults with systemic arterial hypertension.

Methods: This study included 80 young patients (age 23.8 ± 2.

Early Neurodegeneration of the Inner Retinal Layers in Type 1 Diabetes Mellitus.

Purpose: This study explores retinal structural changes in type 1 diabetes without clinically diagnosed diabetic retinopathy (DR).

Methods: Peripapillary retinal nerve fiber layer (RNFL) thickness, macular ganglion cell complex (GCC) thickness, and macular thickness (MT) were measured in 90 type 1 diabetic patients by using spectral domain optical coherence tomography. The values were compared with 100 sex- and age-matched healthy controls.

Choroidal Thickness Changes in the Acute Attack Period in Patients with Familial Mediterranean Fever.

Purpose: The aim of this study was to evaluate choroidal thickness changes during acute attacks of familial Mediterranean fever (FMF).

Methods: Fifty patients with FMF and 50 healthy controls were included. Choroidal thickness of each participant was measured at the foveola and horizontal nasal and temporal quadrants at 500-µm intervals to 1,500 µm from the foveola using spectral-domain optical coherence tomography.

Choroidal thickness in systemic arterial hypertension.

Purpose: To assess choroidal thickness changes in young adults with systemic arterial hypertension.

Methods: This prospective study comprised 80 hypertensive patients and 80 healthy control subjects. Choroidal thickness was measured with spectral-domain optical coherence tomography (SD-OCT) (RS-3000, Nidek).

Long-term Choroidal Thickness Changes After Acute Solar Retinopathy.

Background And Objective: To identify long-term changes in choroidal thickness after solar retinopathy.

Patients And Methods: The study included 25 eyes of 25 men with acute solar retinopathy. Ocular examination, best corrected visual acuity (BCVA), and retinal and choroidal thickness measurements obtained using spectral-domain optical coherence tomography were evaluated.

Diode laser-assisted transcanalicular dacryocystorhinostomy: the effect of age on the results.

Purpose: The aim of this study was to explore the effect of age on the success of transcanalicular diode laser-assisted dacryocystorhinostomy (TCDCR).

Methods: Seventy patients (70 eyes) who underwent transcanalicular diode laser-assisted dacryocystorhinostomy for the treatment of nasolacrimal duct obstruction as a primary surgery were included in this retrospective, nonrandomized study. The patients were divided into two groups according to age.

Corneal pathology in microphthalmia with linear skin defects syndrome.

Purpose: To describe the histopathology of the cornea in microphthalmia with linear streaks (MLS) syndrome.

Methods: Two patients with MLS syndrome underwent penetrating keratoplasty. This study describes the histopathology and investigates immunophenotype of the corneal extracellular matrix by using keratan sulfate and collagen type III antibodies.

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.

Bimatoprost-induced periocular skin hyperpigmentation: histopathological study.

Objective: To investigate light microscopic and ultrastructural changes in bimatoprost-induced skin hyperpigmentation.

Methods: Eyelid biopsy specimens from bimatoprost-treated patients and matched controls were examined by light microscopy and transmission electron microscopy. Using an image analyzer, melanin granules were counted on Fontana-Masson-stained sections, and melanosomes were counted on electron micrographs.

Femtosecond laser photodisruption of human trabecular meshwork: an in vitro study.

The goal of this in vitro study was to test the feasibility of using femtosecond (fsec) laser pulses to fistulize the human trabecular meshwork (TM), and to determine the minimum exposure time and energy dosage needed to create an ablation channel. Corneo-scleral rims were obtained from tissue used for penetrating keratoplasty. Four millimeter tissue strips hydrated in Optisol-GS were used to create partial thickness fistulas in the human TM by focusing a Ti:Sapphire laser beam (45 fsec, 1 kHz, 800 nm) with various pulse energies (7.
