Role of Chorioretinal Biopsy in Inflammatory Eye Disease

Two patients who had similar clinical presentations of bilateral multiple chorioretinal lesions and needed a correct diagnosis underwent chorioretinal biopsy. The biopsy from one patient demonstrated mainly a B cell infiltrate in choroidal and subretinal nodules, while the biopsy from the second patient showed mainly macrophages in the retina. These findings directed the therapeutic approach taken in each patient. Although chorioretinal biopsy is an invasive procedure with the potential for serious complications, the resultant finding may aid in the diagnosis and guide the subsequent management of certain patients presenting with serious ocular findings of undefined etiology

Idiopathic Retinal Vasculitis, Aneurysms, and Neuro-retinitis

Purpose: The authors describe the clinical feature of ten patients with a new syndrome characterized by the presence of retinal vasculitis, multiple macroaneurysms, neuro-retinitis, and peripheral capillary nonperfusion. Methods: The authors evaluated ten patients identified to have clinical features compatible with the syndrome of idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN). Clinical examination findings, sequential fundus photographs (when available), fluorescein angiograms, systemic investigations, response to therapy, and visual outcomes were reviewed. Results: Seven eyes of four patients sustained a marked decrease in visual acuity of 20/200 or worse. Visual loss was due to a combination of an exudative maculopathy and sequelae of retinal ischemia. Capillary nonperfusion was seen in all ten patients and was severe enough to warrant panretinal laser photocoagulation in six patients. Systemic investigations were uniformly noncontributory. Oral prednisone appears to have little beneficial effects on patients with this disorder. Conclusions: Patients with IRVAN have characteristic retinal features that readily identify this syndrome. An increased awareness of this rare syndrome may help to identify sight-threatening complications at an earlier stage. The authors caution against extensive medical investigations.
