Current Indications for Laser Treatment of ROP

Present indications for peripheral retinal ablation are based on the Early Treatment For Retinopathy Of Prematurity (ETROP) Randomized Trial outcomes. Earlier treatment of eyes with high-risk pre-threshold disease significantly reduced unfavorable visual outcomes from 19.8 to 14.3%, and it decreased unfavorable anatomical outcomes from 15.6 to 9.0%. As a result, earlier treatment is indicated for high-risk pre-threshold disease [24, 25]. Based on the International Classification of ROP (ICROP), an algorithm was developed to identify those infants with high-risk pre-threshold disease who may benefit from earlier treatment, resulting in approximately 8% of screened infants requiring treatment versus 6% by the CRYO-ROP standards.

Type 1 ROP (Zone I any stage with plus, Zone I stage 3 without plus and Zone II stage 2–3 with plus) represents those eyes with high-risk disease that would benefit from early treatment, with guidelines stating that treatment should commence within 72 h of diagnosis. Table 7.1 summarizes the recommended early treatment categories.Table 7.1Current guidelines to treat ROP
