Sixth nerve palsy following botulinum toxin injection for facial rejuvenation.

Background: Botulinum toxin A (BTX) has been widely used for a variety of facial esthetic procedures within the last couple of decades. Efficacy and safety of BTX for facial rejuvenation has been extensively studied in multiple randomized prospective controlled trials. Focal weakness is among the most commonly reported adverse effects.

External ophthalmomyiasis seen in a patient from Istanbul, Turkey.

Ophthalmomyiasis externa, results from infestation of the conjunctiva by the larval form of Oestrus ovis. It is usually seen in rural areas. We report a case with ophthalmomyiasis externa in a young man living in an urban area (Istanbul, Turkey) who had no known history of traveling to the rural area.

Analysis of age as a possible prognostic factor for transcanalicular multidiode laser dacryocystorhinostomy.

Purpose. To assess the prognostic value of age on the outcome of transcanalicular multidiode laser dacryocystorhinostomy (TCL-DCR) in patients with acquired nasolacrimal duct obstruction (NLDO). Methods.

The injection of air/oxygen bubble into the anterior chamber of rabbits as a treatment for hyphema in patients with sickle cell disease.

Purpose. To investigate the changes of partial oxygen pressure (PaO2) in aqueous humour after injecting air or oxygen bubble into the anterior chamber in sickle cell hyphema. Methods.

Peripapillary retinal nerve fiber layer changes in asymptomatic essential thrombocythemia patients.

Purpose: To investigate peripapillary retinal nerve fiber layer (RNFL) changes using optical coherence tomography (OCT) in patients with asymptomatic essential thrombocythemia (ET).

Materials And Methods: A consecutive case-control series of 30 patients with asymptomatic ET and age-similar, gender, refractive error, race-matched controls underwent a comprehensive eye examination and OCT of the peripapillary RNFL. Subjects with glaucoma, diabetes mellitus, hemoglobinopaties or other ocular diseases and those who underwent any retinal treatment were excluded.

Effect of accommodation on corneal topography.

Purpose: To investigate the effect of accommodation on corneal topography in healthy subjects.

Methods: Using a Nidek OPD-Scan ARK-10000, corneal topographic images, images of the iris, and the refraction of 18 eyes of 10 normal subjects with a mean age of 26.3 ± 7.

Chloroquine and hydroxychloroquine retinopathy-related risk factors in a Turkish cohort.

To evaluate the role of previously reported risk factors on developing retinopathy in patients treated with chloroquine (CQ) and hydroxychloroquine (HCQ). Ophthalmologic examination, visual field testing, and spectral domain-optical coherence tomography were performed in 31 patients treated with CQ and HCQ. Toxicity diagnosis was proven by electrophysiological assessment.

HIV-related eye disease in patients presenting to a tertiary care government hospital in Turkey.

Aim: To document the ocular involvement in HIV-infected individuals in Turkey and to compare the findings with those from other centers throughout the world.

Methods: In this cross-sectional study, patients with HIV infection being monitored in a tertiary hospital in Istanbul were enrolled. Ocular examination was performed, and the prevalence of ocular manifestations determined.

Screening for retinopathy of prematurity in a tertiary hospital in Istanbul: incidence and risk factors.

Purpose: To study the incidence and risk factors of retinopathy of prematurity (ROP) in premature infants examined in a tertiary hospital in Istanbul.

Methods: Data of infants screened for ROP from April 2007 to September 2009 were retrospectively reviewed. Possible risk factors and eye examinations were recorded and analyzed using the chi-square test and univariate and multivariate regressions.
