Objective To describe the clinical characteristics, staging and presentation of patients with familial exudative vitreoretinopathy (FEVR) in our clinical practice over the last 25 years. Design Case series, retrospective review. Participants We included 273 eyes of 145 patients. Methods Data collected from charts included gender, gestational age at birth, birthweight, age at presentation, referring diagnosis, family history, prior ocular surgery, and clinical presentation in each eye. Eyes with invasive posterior segment procedures before initial presentation were excluded. Main Outcome Measures Demographics on presentation and clinical staging. Results Patients were slightly male predominant (57%) with a mean birthweight of 2.80 kg (range, 740 g–4.76 kg), mean gestational age of 37.8 weeks (range, 25–42), and mean age at presentation of almost 6 years (range, <1 month–49 years). A positive family history of FEVR was obtained in 18% of patients. A positive family history for ocular disease consistent with but not diagnosed as FEVR was obtained in an additional 19%. Stage 1 FEVR was identified in 45 eyes, stage 2 in 33 eyes, stage 3 in 42 eyes, stage 4 in 89 eyes, and stage 5 in 44 eyes. Radial retinal folds were seen in 77 eyes, 64 of which were temporal or inferotemporal in location. Conclusions The FEVR patient population is remarkable for the wide range of age at presentation, gestational age, and birthweight. Although a positive family history on presentation may support the diagnosis of FEVR, a negative family history is of little help. The majority of retinal folds extended radially in the temporal quadrants, but radial folds were seen in almost all quadrants. Fellow eyes demonstrated a wide variation in symmetry. The presentation of FEVR may mimic the presentation of other pediatric and adult vitreoretinal disorders, and careful examination is often crucial in making the diagnosis of FEVR.
