Clinical Case:
A 29-year-old female with bilateral retinal capillary haemangiomas (RCH). A genetic analysis was carried out due to the suspicion of von Hippel-Lindau (VHL) disease, with negative results on 2occasions. There was progression of the RCH in the left eye, leading to a macular epiretinal membrane. The patient was treated with laser, intravitreal ranibizumab, and vitrectomy. Finally, a third genetic test detected a de novo mutation in the VHL gene, and led to the genetic diagnosis.
Discussion:
VHL syndrome causes a complex ocular disease with a difficult diagnosis that requires early treatment of the RCH in order to modify its visual prognosis.
