artery blood flow and the retinal oxygen tension, however, remained elevated for 15 min. Discussion. The VER from anesthetized animals has been extensively studied by others, and our recordings are similar to those they have obtained. It is not clear which cortical structures generate the different waves of the VER, but in the eye it appears to be primarily foveal in origin. We have previously ...

BACKGROUND The purpose of this study was to compare the outcomes of trabeculectomy using single sutures or releasable sutures. METHODS This retrospective study analyzed the medical records of 61 patients who had undergone trabeculectomy using single sutures (n = 33, 54.1%) or releasable sutures (n = 28, 45.9%). The scleral flap was secured with a mean 3.9 (range 3-5) single sutures in 33 pati...

The short-term effects on aqueous humor flow dynamics of single doses of acetazolamide and L-epinephrine, alone and combined, were studied in selected young, normal men. Analysis of aqueous flow before and after medication was facilitated, by graphic representation of flow versus intraocular pressure, the flow curve. Acetazolamide reduced intraocular pressure and Pk of Goldmann without affectin...

PURPOSE To develop a method for measurement of intraocular pressure in conscious, unsedated rats. METHODS. The animal was gently held with a thick fabric mitten, topical anesthetic drops were instilled and the Tono-Pen was applied to the cornea. RESULT Measurements in a total of 51 animals did not differ significantly among four strains studied: the overall mean intraocular pressure+/-standar...

We examined 241 leprosy patients and 135 age-matched healthy controls in central South Korea, measuring intraocular pressure in the supine and the upright positions and measuring the size of the pupils in darkness as an indication of ocular autonomic dysfunction. The mean intraocular pressure was significantly lower in the patients and the mean size of pupils was significantly smaller in the pa...

The effect of atracurium on intraocular pressure was studied by comparing it with pancuronium in a randomised controlled trial. The intraocular pressure was measured in patients undergoing cataract surgery before administration of the muscle relaxant, at 1, 3, and 5 minutes after its administration, and at 1 minute after tracheal intubation. Atracurium was found to decrease intraocular pressure...

The results of a 12-month blind randomised trial comparing the intraocular pressure lowering effect of timolol 0.25% with timolol 0.5% are presented. 27% of patients (22% of eyes) required additional antiglaucoma medication after a minimum time interval of 6 months to maintain an intraocular pressure less than 23 mmHg. The mean reduction in intraocular pressure (from pretreatment values) at 12 ...

PURPOSE To examine the supraciliochoroidal fluid(SCF) by ultrasound biomicroscopy(UBM) at an early stage after trabeculectomy. SUBJECTS AND METHODS Fifteen eyes without post-operative complications were examined by UBM before the operation and less than 2 weeks after trabeculectomy with mitomycin C. RESULTS SCF was detected postoperatively in 6 eyes. One eye had choroidal detachment under i...
