VASOPROLIFERATIVE TUMORS IN INTERMEDIATE UVEITIS.

PURPOSE: To describe patients with intermediate uveitis complicated by vasoproliferative tumors (VPTs). METHODS: Data were collected at seven Uveitis/Ocular Oncology centers on demographic, ophthalmic findings at baseline and at follow-up, and on imaging. The therapeutic intervention, final visual acuity, and duration of follow-up were recorded. RESULTS: A total of 36 eyes from 34 patients (12 men, 22 women; mean age 35.3 ± 14.2 years) were included in this study. Visual acuity at presentation ranged from 20/40 to counting fingers. At the time of VPT diagnosis, intermediate uveitis was active in all eyes. The mean VPT thickness was 3.06 ± 0.86 mm. Local treatment to the VPT was provide in 22 eyes (61.1%) and no local treatment to the VPT in 14 eyes (38.9%). After the VPT was detected, systemic or local treatment for the inflammation was initiated and on follow-up FAs 94.4% of the eyes showed resolution of the vascular leakage. During follow-up of 35.8 months, the 22 VPTs treated locally had a reduction in the tumor thickness to 1.25 mm, whereas the 14 VPTs untreated remained stable (final mean tumor thickness 2.65 mm). CONCLUSION: The presence of active intermediate uveitis accompanied by VPTs suggests the need for an aggressive uveitis treatment.

Frosted branch angiitis complicated by retinal vein occlusion: clinical course and long-term visual outcome.

PURPOSE: Frosted branch angiitis (FBA) is a rare entity characterized by acute panuveitis in the form of a florid translucent retinal perivascular sheathing of both arterioles and venules, with variable uveitis, retinal edema and visual loss. Primary and secondary cases have been described in association with infectious, inflammatory and malignant etiologies. We aim to describe the clinical course and long-term visual outcome of three patients who developed retinal vein occlusion (RVO) and macular edema as a complication of FBA. METHODS: Descriptive case series. RESULTS: Three young healthy patients aged 22, 37 and 45 years presented with sudden visual disturbance secondary to unilateral primary FBA, which improved significantly following high-dose steroid therapy. Several weeks later, RVO developed, with marked cystoid macular edema. Visual improvement was achieved and maintained with anti-VEGF therapy over a follow-up period ranging from 14 to 44 months. CONCLUSION: FBA may be considered a risk factor for the development of secondary RVO because of the severe retinal vasculitis that eventually leads to activation of the coagulation system and retinal thrombosis. It remains to be determined whether antiplatelet therapy needs to be administered prophylactically in such a scenario in order to reduce the risk or prevent the development of RVO.
