Six-month structural outcome for randomized patients^*

Eyes treated	Eyes treated at high-risk prethreshold	Conventionally managed eyes	χ2	P value
Bilateral	286† (5.6)	283† (11.0)	8.3‡	.004
Asymmetric	39§ (0)	36 (2.8)	1.1	.29
Total	325 (4.9)	319 (10)	9.2	.002

^*Data are presented as number (percentage unfavorable) unless otherwise indicated.

^†Less than 290 because of inability to determine the structural outcome.

^‡Based on discordant pairs (21 infants with favorable outcomes in earlier treated eyes and unfavorable outcomes in conventionally managed eyes; 6 infants with unfavorable outcomes in earlier treated eyes and favorable outcomes in conventionally managed eyes).

^§Less than 40 because of inability to determine the structural outcome.
