PURPOSE There is evidence that altered optic nerve head (ONH) blood flow may play a role in the development and progression of glaucoma. In the present study, the baseline characteristics were examined in a study population participating in a clinical trial in which the ocular hemodynamic effects of timolol and dorzolamide were compared. METHODS One(More)
PURPOSE To compare three different methods of measuring corneal thickness (CT) and anterior chamber depth (ACD). DESIGN Prospective clinical trial (Medical University of Vienna, Austria). METHODS Central CT (CCT), CT at four peripheral points, and central ACD were measured in 88 eyes of 44 healthy subjects with the Pentacam (rotating Scheimpflug camera;(More)
Posterior capsule opacification (PCO) is the most common long-term complication with more than 25% overall incidence within 5 years after cataract surgery of the human eye. The goal of the project described in this paper is to devise a fully automated, objective measure of grades of PCO from so-called retroillumination photographs. We review the current(More)
PURPOSE Automated image-analysis systems for objective assessment of posterior capsule opacification (PCO) depend on good image quality. One major drawback is the existence of light-reflection artifacts (Purkinje spots) in retroillumination images of the posterior capsule. Therefore, a software algorithm was developed that removes these artifacts by fusion(More)
BACKGROUND There is evidence that perfusion abnormalities of the optic nerve head are involved in the pathogenesis of glaucoma. There is therefore considerable interest in the effects of topical antiglaucoma drugs on ocular blood flow. A study was undertaken to compare the ocular haemodynamic effects of dorzolamide and timolol in patients with primary open(More)
PURPOSE To determine the subclinical RPE lesions detected by tissue selective polarization-sensitive optical coherence tomography (PS-OCT) in eyes with central serous chorioretinopathy (CSC) and to compare PS-OCT findings to current imaging standards. METHODS In this prospective observational case series, individuals with unilateral or bilateral active(More)
PURPOSE To investigate the course of inflammatory and angiogenic cytokines in the aqueous humor of patients with persistent/recurrent neovascular age-related macular degeneration (nAMD) under ranibizumab monotherapy (IVM) or ranibizumab plus dexamethasone combination treatment. METHODS In this 12-month prospective study, 40 eyes with nAMD were treated(More)
PURPOSE To evaluate the reproducibility of a new colour test, using the Chromatometer CM3. METHODS Twenty healthy subjects were recruited at the Department of Ophthalmology, at the Medical University of Vienna. A total of 40 eyes were tested. Both eyes were tested separately with the Chromatometer CM3. The colour test was repeated after several days. Each(More)
PURPOSE To observe and analyze the daily and weekly changes in morphology and size of Elschnig pearls in eyes with after-cataract. METHODS Pseudophakic eyes with pronounced regeneratory posterior capsule opacification (PCO) were included in this prospective study. High-resolution retroillumination images were taken, and the changes in size and shape of(More)
Nowadays, Posterior Capsule Opacification (PCO)is a common postoperative complication of cataract surgery. The rate of incidence and the intensity of PCO are affected by factors such as type and shape of implanted intraocular lens(IOL), cataract surgical techniques and etc. Clinical quantification of PCO is so subjective that evaluating the effects of these(More)
