Abstract
Purpose
To report a case of monolateral pre-retinal fibrovascular proliferations in a young adult woman, who had suffered from incontinentia pigmenti (IP) during her first month of life.
Methods
Case report.
Results
Circumscribed pre-retinal fibrovascular proliferations, adjacent to a mid-peripheral area of snail track degeneration, were occasionally diagnosed in the left eye of an asymptomatic 18-year-old white female. Careful ocular examination did not reveal any cause of the monolateral vascular abnormalities observed in the posterior segment. A detailed medical history brought to light that the patient has suffered infantile IP, like four other females in her family. The patient did not present any evident malformation of teeth, nails, skeleton or hair. A cytogenetic linkage study documented a chromosomal aberration in the Xq28 band, which confirmed the diagnosis of familial IP (type 2). The fluorescein angiography findings clearly illustrated the minimal retinal involvement in the course of IP.
Conclusions
This case shows that a wide range of etiologies must be considered in patients presenting monolateral pre-retinal fibrovascular proliferations. To correctly manage these uncommon, inherited or acquired, retinal diseases it is better to do a mid-term follow-up, rather than operate immediately, and this enabled us to observe the natural course of the lesion, while awaiting a definitive diagnosis.
