Systemic and Intraocular Methotrexate for the Prevention and Treatment of Proliferative Vitreoretinopathy in Children...

This index study highlights the efficacy and safety of a combined surgical and medical therapy (with intraocular and systemic methotrexate) of pediatric rhegmatogenous retinal detachments (RRD) complicated by proliferative vitreoretinopathy (PVR).

Three pediatric patients with RRD complicated by PVR in the setting of underlying atopic dermatitis and/or uveitis who were treated with a combination of vitreoretinal surgery and intraoperative intravitreal methotrexate (MTX) (40mg) infusion, followed by at least one injection of 200 μg of MTX into the silicone oil-filled vitreous cavity, are reported. In addition, the patients received short-term systemic immunosuppression with systemic (oral or subcutaneous 20 mg weekly MTX for 12 weeks) and/or steroids.

Retinal reattachment with improvement in visual acuity was achieved in all eyes following a single surgery and remained to the final follow-up examination after oil removal. There were no observed side effects of intraocular or systemic MTX.

The safety and efficacy of this combination therapy suggests that it could be a successful strategy for treating pediatric patients with RRD with or without PVR in the presence or absence of underlying inflammatory diseases.
