Ultrawidefield Fluorescein Angiography and OCT Findings in Children and Young Adults with Autosomal Dominant Neovascular Inflammatory Vitreoretinopathy

Purpose

Autosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV) is a rare genetic (CAPN5) autoimmune condition typically diagnosed in adulthood and characterized by a triad of inflammation, retinal degeneration, and neovascularization. We report novel multimodal imaging findings in children and young adults with ADNIV, and early treatment response to short-duration local and systemic corticosteroids.

Design

Retrospective consecutive case series.

Participants

Ten patients aged <25 years with ADNIV and available multimodal imaging.

Methods

The medical records of patients aged <25 years with a diagnosis of ADNIV with ultrawidefield fluorescein angiography (UWFFA) and OCT data were reviewed.

Main Outcome Measures

Ultrawidefield fluorescein angiography and OCT findings at baseline and after local corticosteroids.

Results

Median age at presentation was 14 years (range, 9–24 years). OCT on presentation demonstrated cystoid macular edema in 8 of 20 eyes and symptomatic vitreoretinal interface disease in 2 of 20 eyes. Initial UWFFA demonstrated retinal vascular leakage (20/20 eyes, 100%), peripheral nonperfusion (13/20 eyes, 65%), and retinal neovascularization (6/20 eyes, 30%). Retinal vascular leakage improved with local corticosteroids, and neovascularization regressed with anti-VEGF therapy.

Conclusions

Ultrawidefield fluorescein angiography findings of prefibrotic ADNIV reported in adults were also present in children and young adults. Early testing for a pathogenic CAPN5 variant in at-risk children and regularly scheduled screening for uveitis and retinal vasculitis with UWFFA and OCT may prompt earlier intervention. Short-duration local steroids are effective at treating retinal vascular leakage and macular edema but are not durable, suggesting a potential role for steroid-sparing immunosuppressive therapy. Early treatment may alter the natural history of disease.
