ABSTRACT
Two hundred and fifty eight newborn babies were studied for the presence of retinal hemorrhages between 1-3 days of birth. The overall incidence of retinal hemorrhages was found to be 18.9%. It was observed that the incidence of retinal hemorrhages was higher in unassisted vaginal deliveries than in assisted births. Also, a two fold higher incidence was noted in term infants as compared to preterm babies. No association was seen with birth asphyxia.

A prospective controlled trial of topical 0.1% dexamethasone drops was undertaken with the purpose of determining its efficacy in the prevention of aphakic macular edema. Of the 56 eyes studied specifically at the second and sixth postoperative weeks, none of the 28 in the steroid group showed macular edema, whereas the incidence in the nonsteroid group was 17.1% (P less than .01). The study highlights the role of steroids in reducing the incidence of postoperative macular as well as corneal edema. On the basis of earlier evidence and our observations on the conjunctival hyperfluorescence, the hypothesis for the genesis of macular edema has been modified.

We detected small quantities of prostaglandin F in tear fluid of patients with clinically normal conjunctivae. The prostaglandin F levels were significantly increased in tear fluid or patients with acute vernal conjunctivitis and chronic trachoma. We could not determine the source of prostaglandin in tears.
