Abstract
Purpose:
This report describes a case of acute occlusive hemorrhagic complication after intravitreal melphalan for vitreous seeds in retinoblastoma.
Methods:
A case report is presented.
Results:
Intravitreal melphalan has been used extensively for vitreous seeds in retinoblastoma. Although melphalan is relatively safe at optimal doses, it can sometimes cause inadvertent complications like hemorrhagic events if the drug is administered close to the retina or in more pigmented eyes. We report a case of a 5-month-old patient with bilateral retinoblastoma who underwent enucleation of the right eye and 2 intravitreal melphalan injections in the left eye (20 µg/0.02 mL) at a 1-month interval for persistent vitreous seeds. After the second injection, there was a sudden decrease in the child’s visual acuity in the left eye, and the retina showed multiple intraretinal hemorrhages and diffuse chorioretinal atrophy.
Conclusion:
Intravitreal melphalan may cause acute hemorrhagic complications after intravitreal use for retinoblastoma seeds, especially in pigmented eyes.
