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)
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)
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 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)
Muslims abstain from food and drink from dawn to sunset during the holy month of Ramadan. An extended strict fasting may influence tear secretion and quality. We investigated changes in basal tear secretion (BTS) and tear break-up time (BUT) at the beginning and at the end of fasting on 32 healthy male patients with a mean age of 22.3 +/- 2.9 years. Body(More)
Although unilateral angle closure glaucoma is quite common, simultaneous bilateral acute angle closure is very rare and is usually induced by an external cause. General anesthesia is a triggering factor for acute angle closure glaucoma. We report two cases of simultaneous bilateral angle closure glaucoma following non-ocular surgery under general(More)
Electrocardiographic changes were investigated in 53 patients during subconjunctival drug injections. Decrease in heart-rate of more than 10% or arrhythmia was observed in 25 (47.2%) of the patients, who were considered to have a positive oculocardiac reflex. In the control group of 35 patients, only 3 (8.6%) were found to have a significant decrease 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)
