One-year clinical outcome after laser treatment for retinopathy of prematurity at a tertiary center in Turkey

The purpose of the study is to evaluate the clinical outcome of laser photocoagulation (LPC) in the treatment of retinopathy of prematurity (ROP) at a referral hospital in Turkey. In this retrospective study, a chart review of infants who underwent LPC for ROP between June 2011 and June 2013 was done. Clinical and demographic characteristics, laser parameters, anatomic, and refractive outcomes were evaluated. Totally 113 infants (202 eyes) were enrolled in the study. Of the 202 eyes, 29 eyes had threshold ROP, 141 eyes had prethreshold ROP, and 32 eyes had aggressive posterior ROP (APROP) at initial interventions. The mean gestational age (GA) was 28.13 +/- A 1.99 weeks (range between 24 and 33 weeks), the mean birth weight (BW) was 1,147.77 +/- A 341.77 g (range between 530 and 2,000 g) and the mean postmenstrual age (PMA) at first laser treatment time was 35.79 +/- A 1.74 weeks (range between 33 and 39 weeks). The mean number of laser spots (NLS) applied for each eye was 1,358.05 +/- A 369.91. Eyes with APROP had higher number of NLS than eyes with threshold ROP and prethreshold ROP (P 5D) and strabismus was 2 and 14.3 %, respectively. Laser photocoagulation is an effective therapy for ROP. Early and appropriate laser treatment improves the clinical outcome of the disease
