The diagnosis of<unk>  <unk>  syndrome is made primarily through history and physical exam. A patient's medical history of AIDS increases the likelihood of<unk>  as the diagnosis. An eye exam will show specific hallmark features, including opacified lesions in the peripheral retina without inflammation. There are medical tests that can aid in diagnosing the severity of the disease process, however are not necessary for initial diagnosis. * Imaging studies: may help diagnose the extent of retinal involvement * Optical coherence tomography (OCT): this test allows ophthalmologists to look at<unk>  and inner layers of the retina * Fundus autofluorescence: shows areas of unhealthy cells in the retina * Blood work: the labs can show how immuno-compromised an individual is * Vitreous Tap: Analysis of the fluid in the eye can show the causative organism, such as VZV. Other possible diseases to consider when a patient presents with symptoms similar to<unk>  include: CMV retinitis, ARN, Syphilitic retinitis, Toxoplasma retinochoroiditis, tuberculosis, toxocariasis, fungal or bacterial endophthalmitis Inflammatory: Sarcoidosis, Behcet's, other retinal vasculitides, Neoplastic: intraocular lymphoma, leukemia, metastasis.
