A white reflection seen through the pupil in

(2) End-stage retrolental fibroplasia—caused by a flattened to nodular scarred white retrolental membrane that is nonreactive to light; salvage of vision in either is rare, and is accompanied by persistent anterior persistent hyperplastic primary vitreous humour, due to non-involution of foetal hyaloid artery and accompanying fibrovascular tissue
(3) Visceral larva migrans, due to Toxocara spp

Aunque el diagnostico de la catarata requiere el uso de la lampara de hendidura, se puede sospechar por la disminucion del reflejo rojo retiniano al examinar la retroiluminacion de la pupila con el oftalmoscopio directo, y en casos de cataratas avanzadas blancas sera evidente la leucocoria (la pupila se vera blanca).
