PURPOSE To evaluate the effects of repeated intravitreal ranibizumab injections on corneal sensitivity, corneal sub-basal nerve plexus (SBNP) and peripapillary retinal nerve fiber layer (RNFL) thickness in patients with neovascular age-related macular degeneration (AMD). METHODS Sixty-six eyes of 33 patients who had received unilateral repeated intravitreal ranibizumab injections (0.5 mg/0.05...

  Introduction : Horizontal corneal diameter is one of the diagnostic factors in some ophthalmic diseases. At present American Newborn horizontal corneal diameter is considered as our normal value in Iranian ones, while it may be quite different in Iranian newborns. Early diagnosis is critical in some ophthalmic diseases such as congenital glaucoma and awareness of normal corneal diameter is es...

 ABSTRACT The purpose of this study was the evaluation of cycloplegic effect of homatropine 2% on central corneal curvature and power. 43 volunteers who participated in the study were examined. Thirty-nine of them (28 men and 11 women) which had normal eyes with visual acuity of 20/20 and a mean age of 29.6 ± 6.7 years were selected. Then corneal topography was performed on both eyes. After per...

OBJECTIVE Corneal confocal microscopy is a novel diagnostic technique for the detection of nerve damage and repair in a range of peripheral neuropathies, in particular diabetic neuropathy. Normative reference values are required to enable clinical translation and wider use of this technique. We have therefore undertaken a multicenter collaboration to provide worldwide age-adjusted normative val...

INTRODUCTION The method for measuring intraocular pressure using the Corvis tonometer provides a sequence of images of corneal deformation. Deformations of the cornea are recorded using the ultra-high-speed Scheimpflug camera. This paper presents a new and reproducible method of analysis of corneal deformation images that allows for automatic measurements of new features, namely new three param...

PURPOSE To assess the anterior segment parameters of keratoconus (KC) eyes at different stages of the disease by a new Scheimpflug camera combined with Placido disk corneal topography (Sirius, CSO, Italy) in a sample of the Iranian population. METHODS A total of 225 eyes of 225 individuals comprising 41 suspect KC, 40 mild KC, 71 moderate KC, 48 severe KC and 25 normal eyes were assessed for ...

PURPOSE To report normative results of anterior segment and corneal biometric parameters and their associations in ethnic South Asian Indian adults. METHODS The Singapore Indian Eye Study is a cross-sectional, population-based study of ethnic South Asian Indians ranging in age from 40 to 80 years. Subjects underwent ophthalmic and systemic examination, including imaging with anterior segment ...
