The abortive form of Bourneville-Pringle syndrome
1Department of Ophthalmology, Campus Bio-Medico University, Rome, Italy.
Background/Methods:
To present a 26-year-old woman affected by the abortive form of Bourneville-Pringle syndrome. To our knowledge, this disease is unusual since only very few cases have been reported in the scientific literature at this time.
Results/Conclusions:
Visual acuity was 20/20 in both eyes. No relevant ocular abnormalities were observed excepting two retinal hamartomas, a smaller one in the nasal midperiphery of the right eye and a larger one located along the super-temporal retinal vessels of the left eye. Classical signs of Bourneville-Pringle disease, such as mental retardation and epilepsy, were absent whereas a slight facial adenoma sebaceum and renal cysts represented the solely systemic manifestations of the disease. This case report confirms that retinal phakomata are a typical manifestation of Tuberous Sclerosis, even in the absence of a detected involvement of the brain.
