Results: The study included 03.2150.400 61 eyes of 37 subjects, with 18 (49%) males and 19 females.Seventeen eyes (28%) had hyperopia with spherical equivalent ≥3 D.Refractive astigmatism ≥1.5 D was present in 32% of all eyes.

Nine (38%) subjects had anisometropia ≥2 D.Fifteen (63%) subjects had anisometropia ≥1 D.Conclusion: This study reports the high proportion of amblyogenic refractive risk factors in children with RB, both in RB-affected eyes and contralateral normal eyes.Keywords: retinoblastoma, hyperopia, myopia, astigmatism, amblyopia, anisometropia  .
