Background:
To demonstrate the efficacy of intravitreal methotrexate for treating intraocular lymphoma.
Case:
A 55-year-old immunocompetent Asian man was diagnosed with intraocular lymphoma.
Observations:
The patient was initially managed by intravenous administration of high-dose methotrexate. Because vitreous cells persisted after systemic chemotherapy, methotrexate was given intravitreally thereafter. There was only self-limited corneal epitheliopathy without major complications following intraocular injections. Ocular remission was sustained during a 21-month follow-up.
Conclusion:
Intravitreal methotrexate is an effective, repeatable, and safe treatment for intraocular lymphoma.
