| Title | IRVAN syndrome: A retrospective review of 9 cases from Tunisia |
| Purpose | To describe clinical features, relevant imaging findings, disease course, and response to treatment in 9 patients (18 eyes) with IRVAN syndrome. |
| Methods | A retrospective study about nine patients (18 eyes) diagnosed with IRVAN syndrome |
| Results | Mean age was 33.5 years (4 males and 5 females). Mean initial best-corrected visual acuity (BCVA) was 20/32. Clinical findings included peripapillary exudates in 11 eyes, partial or complete macular star in 11 eyes, multiple aneurysmal dilatations of the retinal and/or optic nerve-head arterioles in 8 eyes, and vascular sheathing in 11 eyes. Thirteen eyes had the stage 2 of the disease, 3 eyes had the stage 3 and 2 eyes had the stage 1. Treatment modalities included peripheral scatter photocoagulation (14 eyes), intravitreal bevacizumab (4 eyes), and intravitreal triamcinolone acetonide (1 eye). Final BCVA was less than or equal to 20/200 in 5 eyes. |
| Conclusion | IRVAN is a rare idiopathic ocular condition. Prognosis may be guarded despite treatment. |
