Cefazolin (2.25 mg) was injected into the vitreous cavity of phakic, aphakic, and aphakic/vitrectomized rabbits; inflamed eyes were compared to controls. Vitreous levels of cefazolin were determined at selected times from 2 to 48 hr, and the half-life was calculated. The effect of inflammation was to increase the half-life or to reduce the rate of elimination of cefazolin from the vitreous cavi...

Background: Pediatric cataract is responsible for 200.000 of preventable blindness in children. Early extraction and correction after the lens removal critical. Secondary intraocular (IOL) implantation might be considered when child intolerant to contact lenses/spectacle wear. Only a few study has been done regarding secondary IOL aphakic Objective: This was aimed describe characteristic childr...

A 38-year-old man with longstanding low intraocular pressure (IOP) in his right aphakic eye presented with severe pain and high IOP (35 mm Hg). On examination, visual acuity was light perception. The central and peripheral portions of the iris were directly opposed to the posterior corneal surface and synechial closure of the pupil margin. B-scan ultrasonography showed posterior vitreous detach...

A DIALYSIS, or separation of the two ectodermal retinal layers at the ora, occurs in the following circumstances: (1) In the senile eye, when the dialyses are usually small and multiple and situated anywhere in the periphery. (2) In the aphakic eye, when the dialyses may be single or multiple, often in the upper half of the retina. (3) In the normal emmetropic eye which has received definite tr...

At a level of 0.01 per cent in isolated, pooled calf aqueous humor, epinephrine bitartrate is converted into a series of pigmented. photoproducts by exposure to near UV light for only a few hours. The brown photoproducts, but not adrenochrome, bind to and alter the electrophoretic mobility of aqueous-humor proteins. The rapidity and mild conditions required for the above-described effects to oc...

The purpose of this paper is to consider the long-term results of the iris clip lens in senile aphakia. It is not intended to discuss the many different forms of intraocular lens implants. Ophthalmic surgeons are well aware of the discouraging shortand long-term failure rate when contact lenses are used to correct aphakia, and this has stimulated renewed interest in intraocular lens implants in...
