Bleb injections ward off orbital tumours

Bleb injections of subconjunctival chemotherapy lower the risk of developing orbital tumours in patients with retinoblastoma.

Bleb injections of subconjunctival chemotherapy lower the risk of developing orbital tumours in patients with retinoblastoma.

Professor Brian Mohney and his team, Department of Ophthalmology, Mayo Clinic, Rochester, Minnesota, USA, completed a non-comparative interventional case series on two patients who presented with bilateral retinoblastoma.

Subconjunctival chemotherapy was administered to both patients to reduce the risk or orbital tumour seeding after intravitreal injection. The outcome measures were ocular toxicity levels and the presence or absence of viable tumour cells at the injection site.

Subconjunctival chemotherapy bleb injections before intravitreal drug delivery seem to reduce the risk of orbital tumour seeding in patients with advanced stage retinoblastoma.
