to evaluate structural outcomes in preterm babies that underwent laser photocoagulation for type 1 ROP.
12 babies with good structural laser outcome have been followed up to 4 years. All babies periodically underwent visual tests evaluation: reaction to light, fixation, tracking, reaction to colored or B/W stimuli, staring at distance, visual acuity (using LEA symbols) and visual fields. In the same day retinoscopy and wide field FA under general anesthesia was also performed.
Only 5 eyes among 24 (20,8%) had a 0,30 LogMAR or better best corrected visual acuity; visual field was normal in 7 eyes (29,2%), reduced or without response in 17 eyes (70,8%). At autorefractometry we found that 10 eyes among the total 24 were myopic, 12 eyes were hyperopic, 9 eyes had negative astigmatism and 12 eyes had positive astigmatism. FA abnormalities are classified as follow: absence of FAZ (foveal avascular zone) in 6 eyes, hyperfluorescent lesion in 12 eyes and hypofluorescent lesions in 20 eyes.
Although this study is limited by the population size it is possible to hypothesize a correlation between FA findings and visual functional outcomes in severe ROP treated with laser photocoagulation.
