A prospective study of xenon arc photocoagulation for central retinal vein occlusion.

Twenty patients with central retinal vein occlusion were randomly divided into two groups in a prospective study to evaluate the effects of xenon are photocoagulation in central retinal vein occlusion. The patients in one group were treated with 360 degrees scatter xenon photocoagulation and the others received no treatment. The average follow-up was 18 months. There were no cases of rubeosis or neovascular glaucoma in the treated group. Two patients in the untreated group developed rubeosis with subsequent neovascular glaucoma. There was no significant difference in the visual prognosis or in fundus neovascularization between the groups.

Penetration of amikacin into the aphakic eye.

An experiment was designed to see if an aminoglycoside antibiotic, amikacin, would penetrate the vitreous of rabbits in greater concentrations in the postoperative aphakic eye than in the normal eye. Phakic and aphakic eyes were treated with amikacin by topical, subconjunctival, and intramuscular methods separately and combined. Bioassays of aqueous, anterior vitreous, and posterior vitreous revealed that concentrations of amikacin in ocular fluids after intramuscular administration were greater in the aphakic eye as compared to the normal eye; however, concentrations in the vitreous did not reach reliably bactericidal concentrations even when all three methods of administration were combined.

A shorter scleral needle.

A scleral needle for retinal detachment surgery, which has a shorter length than has previously been available, has been developed. This shorter length makes the passage of the needle easier in the limited space available posterior to the equator of the eye.
