PURPOSE: To evaluate the clinical characteristics and treatment outcomes of idiopathic retinitis, vasculitis, aneurysms, and neuroretinitis (IRVAN) in a cohort of Chinese patients. MATERIALS: The clinical history, imaging evaluation, treatment and outcomes of 42 eyes in 21 patients diagnosed with IRVAN in a 15-year period were reviewed. RESULTS: Most patients were females (90%) ranged from 15 to 58 years old. The initial decimal best corrected visual acuity (BCVA) of the patients ranged from light perception (LP) to 1.5 (0.55 ± 0.38). Eighteen eyes were in stage 2; 21 eyes in stage 3; and 1 in stage 5 at the initial visits according to the present staging system. Two eyes had vitreoretinal fibrovascular proliferation (FVP) and tractional retinal detachment (RD) at the initial visit. Intra-retinal microvascular abnormality (IRMA) was found in 7 eyes. Thirty-four eyes received retinal photocoagulation, 27 of which were pan-retinal photocoagulation (PRP). Total of 8 PPV were performed for VH, vitreoretinal FVP and RD, and macular epimembrane. Aneurysms on the head of optic nerve and artery bifurcations disappeared in 8 eyes and decreased in number in 2 eyes 1 year after photocoagulation. However, the BCVA of the patients did not have significant difference from that at the initial visits (P = 0.534). Seven eyes suffered severe visual impairment (BCVA ≤ 0.1) due to vitreoretinal FVP and tractional RD (3), exudative maculopathy (2), paracentral acute middle maculopathy (PAMM)(1), and neovascular glaucoma (NVG) (1). CONCLUSIONS: We found that IRVAN have a predilection to female gender. Vitreoretinal FVP and tractional RD and exudative maculopathy are major causes of severe visual impairment in IRVAN patients. We propose to revise the present staging system to include vitreoretinal FVP and RD in the staging of IRVAN patients.
