Spontaneous regression of retinal angiomatous lesions in v. Hippel-Lindau disease (VHL).

BACKGROUND

Very little documentation of spontaneous regression of an angiomatous retinal lesion in v. Hippel-Lindau disease (VHL) exists. It is commonly believed that a spontaneous change of hemangiomas into fibrotic lesions occurred.

PATIENTS/

METHODS

Follow-up examinations of four patients with VHL in the Freiburg VHL study were carried out.

RESULTS

A 16-year-old girl revealed a vascular lesion at the border of the optic disc. Control examination nine years later revealed complete spontaneous regression of the retinal vascular changes. A slight retinal vascular change at the superior border in her right eye was found in a 36-year-old woman. A control examination 20 years later revealed regression of the lesion. A 41-year-old woman showed in the retinal periphery a small fibrotic white hemangioma with a pigmented feeder vessel as sign of spontaneous tumor regression. A 12-year-old boy had a retinal microaneurysm inferior to the optic disc that disappeared several years later.

CONCLUSION

Documentations of spontaneous regression of minor angiomatous retinal lesions in VHL exist. Such vascular changes are rare. Every retinal lesion should be controlled by follow-up examination and documentation. In case of retinal lesion growth, treatment is necessary.
