Physiological effects of laser trabeculotomy in rhesus monkey eyes.

چکیده
Discussion. A significant increase in facility of outflow did not occur to account for the decrease in intraocular pressure. We conclude from this experiment that the mechanism of action for the ocular hypotensive effect of timolol is not by increasing the outflow of aqueous humor from the eye. We believe that it is most likely that timolol decreases the secretion of aqueous humor, and experiments directly testing this hypothesis are underway.

Influence of intraocular pressure and trabeculotomy on aqueous outflow in enucleated monkey eyes.
Quantitative aqueous perfusion was performed at a series of pressures from 5 to 50 mm. Hg in enucleated monkey eyes on which an iridotomy had been performed to minimize artificial changes in depth of the anterior chamber. Total facility of outflow became less when the pressure was increased, similar to what was observed in separately reported experiments on enucleated human eyes. When the press...
متن کاملMyocardial Infarction in a Rhesus Monkey
Myocardial necrosis can be result from a number of causes including nutritional deficiencies, chemical and plant toxins, ischemia and metabolic disorder. The outcome of myocardial necrosis varies depending on the extent of the damage (Donald 2001, Jubb 1993, Radostits 1994, Vanvaleet 1986). Myocardial infarction without demonstrable of atherosclerosis were reported in a rhesus macaque (Gonder 1...

PURPOSE To evaluate the effects of ultrashort laser pulses of visible wavelengths on the retinas of rhesus monkey eyes and to perform threshold measurements for minimum visible lesions (MVLs) at pulsewidths from nanoseconds to femtoseconds. METHODS Single laser pulses at visible wavelengths were placed within the macular area of live rhesus monkey eyes at varying pulse energies at five pulsew...

Background and purpose : Congential glaucoma is one of the causes of blindness in pediatric age group and the patients are resistante to drug theragy so the purpose is to determine the success rate of trabeculotomy and trabeculectomy glaucoma surgery. Materials and Methods : All Patients (16 eyes) with congental glaucoma referred to E.H Hospital in 1971-1977 They have Trabeculotomy first ,...
متن کاملMonochromatic ocular wave aberrations in young monkeys
High-order monochromatic aberrations could potentially influence vision-dependent refractive development in a variety of ways. As a first step in understanding the effects of wave aberration on refractive development, we characterized the maturational changes that take place in the high-order aberrations of infant rhesus monkey eyes. Specifically, we compared the monochromatic wave aberrations ...
