Introduction
Background
von Hippel-Lindau disease (or von Hippel disease) exhibits the characteristics of congenital capillary angiomatous hamartomas of the retina and the optic nerve.
Pathophysiology
This condition is a benign capillary hamartoma with autosomal dominant inheritance with variable penetrance. The responsible gene is on chromosome 3 (3p25-p26). This gene behaves as a typical tumor suppressor gene, as defined in Knudson's theory of carcinogenesis. A nonhereditary form also exists.Retinal capillary hemangiomas (von Hippel disease) are seen in 50% of patients. Similar tumors in the CNS, such as hemangioblastomas in the cerebellum (ie, von Hippel-Lindau disease), and other organs of the body are present in 25% of patients. Cysts of the pancreas and kidneys may coexist. Pheochromocytoma and hypernephroma also are known to occur.
Retinal capillary hemangiomas, usually supplied by large dilated feeder vessels, may occur in any part of the retina. Serum leakage from these vessels and hemangiomas leads to retinal exudates. Organized fibroglial bands with traction retinal detachment and vitreous hemorrhage may occur with their own secondary sequelae.
On the microscopic level, the basic component is a capillary hemangioma comprised of endothelial cells and pericytes. The foamy stromal cells between the capillaries stain positive for glial fibrillary acid protein and neuron specific enolase.
Frequency
United States
This condition is uncommon in the general population.
Mortality/Morbidity
Untreated von Hippel-Lindau disease can cause serious visual impairment.
Sex
No known gender predilection exists.
Age
von Hippel-Lindau disease usually presents in the second to third decade of life.
Clinical
History
- Patients may note a decrease in visual acuity.
- Have a high index of suspicion of ocular lesion if a patient presents with diagnosis of von Hippel-Lindau disease.
Physical
- Occasional lesions are noted on routine examination.
- Loss of vision usually is caused by lipid exudate in the macula area. If left untreated, this exudation can lead to retinal detachment. Vitreous hemorrhage, secondary iris neovascularization with glaucoma, and cataract formation may follow.
- Angiomas are the most common presenting signs and symptoms of von Hippel-Lindau disease.
