PURPOSE To evaluate the incidence, clinical features and evolution of polypoidal choroidal vasculopathy (PCV) in our population. METHODS Retrospective study of patients diagnosed with exudative and/or hemorrhagic maculopathy including age-related macular degeneration in the last two years and who have undergone a complete ophthalmologic exploration and(More)
AIMS To evaluate a new method for measuring haemoglobin (Hb) levels and quantifying the colour changes in the optic nerve head of multiple sclerosis (MS) patients to detect axonal loss and consequently optic disc atrophy. MATERIAL AND METHODS 40 MS patients and 40 age and sex-matched healthy subjects were included in this prospective cross-sectional study(More)
PURPOSE We evaluated and compared the ability of a new method for measuring hemoglobin (Hb) levels at the optic nerve head (ONH) to that of visual field evaluation, scanning laser ophthalmoscopy (HRT), scanning laser polarimetry (GDx), and optical coherence tomography (OCT) for diagnosing glaucoma. METHODS Healthy eyes (n = 102) and glaucomatous eyes (n =(More)
PURPOSE In the present study, we evaluated changes in the retinal nerve fiber layer (RNFL) and optic disk color (i.e., the level of paleness as an indirect sign of axonal loss) in patients with Alzheimer's disease (AD) compared with healthy controls. The usefulness of this method as a new biomarker for AD was also evaluated. METHODS Fifty-six patients(More)
PURPOSE To compare the pre-, intra- and postoperative pain scores and complication rates in trabeculectomy under contact-topical anaesthesia versus peribulbar injection anaesthesia. METHODS A total of 100 patients selected to undergo primary trabeculectomy were randomly allocated to receive either contact or peribulbar anaesthesia. Patients were asked to(More)
PURPOSE To compare the combined levels of comfort, the presence of complications and the results of phacotrabeculectomy surgery obtained with 2 different forms of anaesthesia: topical contact anaesthesia and peribulbar injected anaesthesia. PROCEDURES In total, 120 consecutive patients undergoing phacotrabeculectomy were randomly assigned to each(More)
PURPOSE To compare the efficiency and safety of contact-topical anesthesia versus peribulbar injection anesthesia for phacotrabeculectomy. MATERIALS AND METHODS A total of 80 patients undergoing combined cataract and glaucoma surgery were randomly allocated to receive either contact or peribulbar anesthesia. No systemic sedatives were used in either(More)
Objective. To evaluate a new method of measuring hemoglobin (Hb) levels and quantifying the color changes in the optic nerve head of Parkinson's disease (PD) patients. We also compared differences in retinal nerve fiber layer (RNFL) thicknesses obtained using spectral domain optical coherence tomography (OCT) device between PD group and healthy group.(More)
PURPOSE To determine the penetration of grepafloxacin into ocular tissues during experimental ocular inflammation. METHODS 10 albino and 10 pigmented rabbits underwent a continuous intravenous infusion of the drug 24 h after injecting Salmonella typhimurium toxin intravitreously, creating ocular inflammation. The animals were killed and grepafloxacin(More)
PURPOSE To compare the ability to identify RNFL alterations between standard images and SLO images in a group of patients suffering from ocular hypertension. METHODS We evaluated RNFL in sixty patients with ocular hypertension and with normal perimetry, by using standard photography and SLO. Two different independent observers evaluated the images on two(More)
