Seventeen eyes with retinal detachment secondary to retinal breaks in the colobomatous area were managed by vitrectomy procedures. Endodrainage was done through the break in the colobomatous area, with simultaneous fluid-air exchange. Endolaser photocoagulation was performed along the colobomatous margin posteriorly, while the anterior portion was treated by transscleral cryopexy. Silicone oil was then exchanged with air. In nine cases, the silicone oil had to be removed for complications such as emulsification, glaucoma, and keratopathy; in three of these eyes, oil removal resulted in recurrent retinal detachment. At the 2-month follow-up visit, there was 100% anatomic success, and 12 eyes (70.6%) recovered visual acuity of 10/200 or better. Of the 11 eyes with follow-up of more than 6 months, in 9 (81.8%) the retina remained reattached at last-follow up, and in 6 eyes (54.5%) a visual acuity of 10/200 or better was obtained.
The efficacy of 1.0% apraclonidine (para-aminoclonidine) in preventing the rise of intraocular pressure following anterior segment, laser surgery was evaluated in a randomised double-masked study. Ninety-nine consecutive patients requiring laser treatment of the anterior segment were included in the study. They were randomised into two groups, one receiving 1.0% para-aminoclonidine and the other placebo (vehicle of para-aminoclonidine). The drug caused a statistically significant reduction in pressure after the laser treatment without causing clinically significant side effects such as bradycardia or hypotension.

A retrospective study involving 40 eyes of 40 patients with giant retinal break is presented. A comparison is attempted between cases where silicone oil is used and in cases where it was not used. The final success rate was found to be same in the two groups on long term follow-up.
