Progression of Pseudovitelliform Macular Dystrophy

Le résumé fourni par la source

Pseudovitelliform macular dystrophy is a dominantly inherited macular disorder. It is characterized by the presence of horizontally oval yellowish deposits within the maculas that are approximately one-third disc diameter in size. As classically described, progression of the lesions over a follow-up period of as long as six years has not been described and the prognosis for retention of good visual function is excellent. We report the ophthalmoscopic appearance of six eyes of three patients from a very subtle alteration of macular pigmentation to severe disruption of macular architecture, and demonstrate in one of our patients drastic deterioration in both ophthalmoscopic appearance and visual function over a three-year period of follow-up. The prognosis for retention of good vision in this disorder must include the possibility of the eventual development of severe visual impairment.
