Abstract:
An 89-year-old female presented with acute visual impairment and large cells in the vitreous cavity of the left eye. The patient was treated for a suspected intraocular lymphoma. In the follow-up a retinal detachment was diagnosed and treated via pars plana vitrectomy. A resection of the subretinal traction membrane following retinectomy was performed. The histological findings did not reveal any indications of a lymphoproliferative process. A ruptured choroidal neovascularization (CNV) with peripheral exudative hemorrhagic chorioretinopathy (PEHCR) and subretinal membrane formation was diagnosed. There were no signs of malignancy. The resection of a subretinal traction membrane poses a challenge for the vitreoretinal surgeon but can provide the possibility of visual improvement.
