Diode laser photocoagulation to the ridge and avascular retina in threshold retinopathy of prematurity.

PURPOSE: To report results applying diode laser photocoagulation to both the peripheral avascular retina and the ridge in stage 3+ threshold retinopathy of prematurity.

METHODS

The authors performed a retrospective review of 82 consecutive eyes in 43 preterm infants with threshold disease who had both the peripheral avascular retina and the ridge treated with diode laser photocoagulation. With a minimum follow-up of 3 months, these eyes were evaluated for intraoperative and postoperative complications and long-term anatomic results.

RESULTS

A favorable anatomic outcome occurred in 79 eyes (96%). There were no intraoperative complications. Postoperative intraocular hemorrhage occurred in eight eyes (10%) and resolved without sequelae. Supplemental laser was required in only two eyes (2%).

CONCLUSIONS

Diode laser photocoagulation to the ridge and peripheral avascular retina in threshold retinopathy of prematurity is associated with a favorable anatomic outcome. The risk of postoperative intraocular hemorrhage and the need for supplemental laser photocoagulation is low.
