PURPOSE To evaluate the effect of Concanavalin A (Con A) on cataract formation in New Zealand Albino rabbits. Uveitis is a chronic inflammatory condition of the eye involving the anterior and/or posterior segments. It may be acute or chronic and is associated with the development of posterior subscapular cataract over time. Con A is a nonspecific(More)
Lens regeneration occurs in New Zealand albino rabbits after endocapsular lens extraction, which leaves the anterior and posterior lens capsules relatively intact. Slit-lamp photography, histologic studies, and lens protein analysis confirmed the differentiation of lens fibers. In the current study, we performed a sequential analysis of the regenerating(More)
PURPOSE To evaluate the regenerative capacity of the adult rabbit lens after removal of a Concanavalin A-induced posterior subcapsular cataract. METHODS Cataractogenesis was induced by intravitreal injection of Concanavalin A in adult New Zealand albino rabbits. At 7 mo postinjection, the cataracts were removed. Endocapsular lens extraction was performed(More)
In studies conducted by numerous investigators for 150 years, lenses regenerated following endocapsular lens extraction in New Zealand albino rabbits have been irregular in shape, appearing primarily doughnut-shaped as a result of lack of lens growth at the site of the anterior capsulotomy and its adhesion to the posterior capsule. In the present study, we(More)
A 128-channel cable-telemetry EEG monitoring system has been developed for use on patients undergoing intensive neurodiagnostic monitoring with invasive intracranial electrodes. A unique head mounted preamplifier/multiplexor design allows continuous recording from any combination of intracerebral, subdural, epidural or surface electrodes. A computer is used(More)
PURPOSE To compare vitrectomy procedures and visualization of posterior segment structures through multifocal silicone intraocular lenses (IOLs) with the same procedures through monofocal silicone IOLs in rabbit eyes. DESIGN Experimental study. PARTICIPANTS Twelve eyes of six rabbits. METHODS Each rabbit eye underwent phacoemulsification of the lens(More)
We evaluated the effect of focal laser photophacoablation on (1) a normal lens and (2) previously induced traumatic anterior cortical and posterior subcapsular cataracts in New Zealand albino rabbits. A Q-switched neodymium:YAG (Nd:YAG) laser was used to deliver 6 to 97 50 microns laser spots of 2.0 mJ to 8.3 mJ of energy/pulse to the normal lens. A(More)
Secondary cataract growth commonly occurs after extracapsular cataract extraction. The proliferation of this regrowth occurs at rates related to many factors. In this study, the authors analyzed the amount of lens regeneration after endocapsular lens extraction that leaves the anterior and posterior capsules relatively intact. The analysis was performed in(More)
