Manifestations inhabituelles du rétinoblastome.

: Among the 185 retinoblastoma patients seen at the Lausanne Retinoblastoma Clinic from 1963-1993, 24 (14%) first presented with another sign than classical leukocoria (60.5%) or strabismus (21.5%). Most of these atypical signs were related to inflammatory complications of unrecognized retinoblastoma; they consisted of low vision (1.5%), hypopyon (2%), ocular redness and pain (1.5%), ocular redness and buphtalmia (1.5%), as well as photophobia and headaches (1.5%). The presence of unexplained chronic ocular signs during childhood should always raise the possibility of an underlying retinal malignancy.
