PURPOSE The Reichert ocular response analyzer (ORA) measures corneal biomechanical properties in vivo by monitoring and analyzing the corneal behavior when its structure is submitted to a force induced by an air jet. This study was designed to examine corneal biomechanical properties and intraocular pressure in patients with systemic sclerosis (SSc) and to(More)
PURPOSE To evaluate the effects of betaxolol and latanoprost on ocular blood flow and visual fields in patients with primary open-angle glaucoma (POAG) by means of an observer-masked, prospective clinical study. METHODS Thirty-two patients with newly diagnosed POAG were included in the study. The patients were randomized into two groups. The first group(More)
BACKGROUND & OBJECTIVES Sildenafil citrate is an oral medication used to treat male impotence by the inhibition of phosphodiesterase-5 in the corpus cavernosum and subsequent facilitation of penile erection. Though the ocular side effects of sildenafil have been reported, no information is available on the histopathologic effects of chronic use of(More)
PURPOSE To determine the effects of Islamic religious fasting on intraocular pressure. METHODS The authors measured diurnal intraocular pressure values during religious fasting and 1 month later in 38 healthy male volunteers with a mean age of 22.4 +/- 2.7 years. Body weight and urine specific gravity were determined to assess the extent of dehydration(More)
A surgical technique was developed for traumatic iridodialysis repair using a small partial-thickness scleral flap and a 24-gauge disposible hypodermic needle. This procedure is a "direct iridodialysis-site approach" closed chamber technique with minimal surgical trauma that can be used in phakic, pseudophakic, or aphakic eyes.
PURPOSE To determine if multifocal electroretinogram (mfERG) testing shows abnormalities that correspond to perimetric defects in HIV positive patients without infectious retinitis. METHODS We studied three groups of patients: HIV negative controls, HIV high CD4 nadir patients (lowest CD4 T cell count is over 100) and low CD4 nadir patients (below 100 for(More)
We describe a realistic and inexpensive experimental cataract model for phacoemulsification training. After a capsulorhexis is performed, a deep cavity in the lens of an enucleated sheep eye is formed by phacoemulsification through a lateral incision. An undamaged human cataractous lens nucleus obtained by extracapsular cataract extraction is inserted in(More)
PURPOSE To present ocular findings in a measles epidemic outbreak among young adults. METHODS Ophthalmic lesions in an unselected group of 61 young military personnel with measles were followed. Eighteen of the patients had symmetric keratitis in both eyes. They were treated with diclofenac sodium eyedrops qid in the right eye, while the left eye was(More)
AIMS To compare the non-decanted (standard) 4 mg versus the decanted 20 mg intravitreal triamcinolone acetonide (IVTA) injections and to assess their effect on intraocular pressure (IOP). METHODS We retrospectively reviewed the records of 92 consecutive eyes, which received an intravitreal injection of either dose of triamcinolone acetonide, at a single(More)
AIMS To investigate the cardiovascular and respiratory effects of topical latanoprost 0.005% and topical betaxolol 0.25% monotherapy in newly diagnosed glaucoma patients. METHODS Fortynewly diagnosed glaucoma patients were enrolled in this prospective, observer-masked, randomized, parallel study. Patients received either latanoprost 0.005% or betaxolol(More)
