[The first experience of using OCT in diagnosis of primary and residual retinoblastoma]

21 children with retinoblastoma (32 eyes, 36 lesions) were examined using optical coherence tomography (OCT). Pathognomonic features of initial primary exophytic, endophytic and mixed retinoblastoma were revealed OCT-control allowed to estimate combined treatment efficacy (chemotherapy, brachytherapy, transpupillary thermotherapy) and to reveal signs of latent growth. Thus revealed OCT signs of primary, residual retinoblastoma, retinal scar, zones of latent growth allow early estimation of appropriateness of combined eye-preserving treatment.
