Retinal Hemangioblastoma (Small, Extramacular or Extrapapillary) in Von Hippel-Lindau Syndrome — Early-Stage Management
Retinal hemangioblastomas are a hallmark ocular manifestation of Von Hippel-Lindau (VHL) syndrome. When detected at an early stage — small, extramacular, or extrapapillary — these lesions present a window for prompt, effective intervention before they become symptomatic and substantially harder to manage.
Clinical scenario
A patient with Von Hippel-Lindau syndrome is found to have a small retinal hemangioblastoma in an extramacular or extrapapillary location. The lesion is at an early stage and currently asymptomatic. Symptomatic RHs tend to be larger and are significantly more difficult to treat with available therapies; early, asymptomatic RHs are far more amenable to treatment. Prompt intervention is therefore indicated even for small lesions.
Treatment approach (partial)
Prompt treatment of the retinal hemangioblastoma is indicated. The protocol specifies a focal ablative technique as the intervention of choice — the full selection criteria, procedural sequence, and follow-up guidance are detailed in the complete protocol.

Even small extramacular/extrapapillary RHs should be treated promptly.
Symptomatic RHs are often large and can be difficult to treat with currently available therapies, whereas early RHs are typically asymptomatic and can be treated easily with laser photocoagulation or cryotherapy.
