Abstract

Every investigation into the efficacy and role of photocoagulation in the management of PHM has been handicapped by the lack of a valid control series. In all first eyes, the results of photocoagulation are better than in second eyes. The increased salvage rate of central visual acuityof 20/50 or better in first eyes without photocoagulation is on the order of 15.8 percent to 28.6 percent-versus 25 to 38 percent in first eyes with photocoagulation (an average of 54 percent salvage rate for all first eyes). However, in second eyes, even though the number of eyes is small, it appears that nonphotocoagulated eyes do better than those that have been photocoagulated: 46 percent of nonphotocoagulated second eyes versus 33 percent of second eyes with photocoagulation retain central vision of 20/50 or better. Comparison of our results with some of the other published studies indicates some disparity in results [1-5], arising, most plausibly, from variations in the severity of the maculopathy just prior to photocoagulation. It is our contention that carefully designed prospective studies are needed, in which cases would be randomized for treatment in groups classified according to severity of the process (for example, size of SNV, proxi...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
