Abstract

In this retrospective cohort study, we describe intrafamilial phenotypic variability of retinal hemangioblastoma (RH) in families with von Hippel-Lindau (VHL) disease. Patients with molecularly confirmed VHL evaluated at our institution were identified, and records were reviewed. For individuals with sufficient follow-up and imaging (n=27), the number and location of RHs at the initial and most recent follow-up visits were recorded along with treatment method and systemic manifestations. A strategy for zonal classification of RH location was used. Intrafamilial phenotypic variation was identified in 3 families. Intrafamilial phenotypic variability of RH exists between family members with VHL with the same genetic mutation.

Figure 1.
Family 1 with mild phenotype in the right eye of a 61-year-old (A) compared with severe phenotype in the right eye of a 60-year-old (B). The patient in B had coexisting retinopathy of prematurity resulting in temporally dragged fovea; however, the chorioretinal scars in the figure are due to treated retinal hemangioblastomas (RHs). Family 2 with mild phenotype in the left eye of a 53-year-old (C) compared with severe phenotype in the left eye of a 33-year-old (D). Family 3 with mild phenotype in the right eye of a 52-year-old (E) compared with severe phenotype in the right eye of a 48-year-old who underwent pars plana vitrectomy with placement of silicone oil due to RH-induced tractional retinal detachment (F).
