Transient Increased Exudation after Photodynamic Therapy of Intraocular Tumors.

This article is from Middle East African Journal of Ophthalmology , volume 20 . Abstract To report transient increased exudation after photodynamic therapy (PDT) of three different intraocular tumors (retinal hemangioblastoma, retinal astrocytoma, amelanotic choroidal melanoma). PDT with verteporfin (6 mg/m2 body surface area) was delivered at a dose of 50 J/cm2 and intensity of 600 mW/cm2 over 83 s. All patients experienced decreased vision within a few days following PDT. Optical coherence tomography showed development of subfoveal fluid in all cases and noncystoid intraretinal edema in the eye with juxtapapillary retinal hemangioblastoma. There was complete absorption of retinal/subretinal fluid with improvement of visual acuity to 20/20 in all cases between 3 weeks to 4 months after PDT.
