A case of acquired retinal astrocytoma treated by photodynamic therapy

Purpose: To report a case of retinal astrocytoma treated by photodynamic therapy. Case: A 27-year-old woman presented with impaired vision in the right eye since 2 years before. Corrected visual acuity was 0.7 right and 1.2 left. The right fundus showed a yellowish-white elevation of 2.5 disc diameters temporal to the disc. Optical coherence tomograph showed serous retinal detachment around the lesion. Height of the tumor increased to 3.5 mm 5 years later with bullous retinal detachment. Visual acuity decreased to 0.03. The findings led to the diagnosis of retinal astrocytoma. Three sessions of photodynamic therapy was followed by decreased height of the tumor to 1.5 mm 5 months later. Bullous retinal detachment disappeared with visual acuity maintained at 0.03. Conclusion: Photodynamic therapy was effective for retinal astrocytoma.
