AIM: To report photographically the evolution of an @entity4607 of the left @entity1781 head over a 2-year follow-up in a @entity1 with @entity6391 . METHODS: A 14-year-old @entity1 was seen in the medical retina clinic with a 3-year history of @entity15535 . Best corrected visual acuity was 6/18 in both eyes. Colour vision was normal in both eyes and confrontation fields showed peripheral constriction. Fundus examination revealed bone spicule pigmentary changes at the retinal mid periphery typical of @entity6391 and superficial globules at the margins of both @entity1781 heads. Electrodiagnostic tests confirmed moderately severe @entity6391 with macular involvement bilaterally. RESULTS: Two years later, the ocular examination was unchanged except for the appearance of the @entity1781 @entity75 in the left eye. There was an increase in the size of the lesion which was diagnosed as an @entity4607 . Further investigations were recommended to exclude @entity4786 and @entity2916 . CONCLUSION: Astrocytic hamartomas of the @entity1781 head and @entity1781 head drusen have both been described in @entity1 with @entity6391 . They can be a diagnostic dilemma although drusen are more common (10%). To differentiate these two entities it is very important to document any growth during the follow-up period which is suggestive of @entity4607 rather than optic disc drusen.
