  • Title: Vitreous hemorrhage complicating retinal astrocytic hamartoma.
    Author: Kroll AJ, Ricker DP, Robb RM, Albert DM.
    Journal: Surv Ophthalmol; 1981; 26(1):31-8. PubMed ID: 7280993.
    Abstract:
    Tuberous sclerosis classically presents a triad of mental deficiency, seizures and adenoma sebaceum. Among the ocular manifestations are astrocytic hamartomas in the retina. This paper describes the case of a 24-year-old man with tuberous sclerosis who had recurrent vitreous hemorrhage from a large epipapillary astrocytic hamartoma in the left eye. Pars plana vitrectomy cleared the vitreous and bimanual bipolar coagulation of tumor bleeding points was done. Fragments of the friable tumor were obtained with the vitrectomy instrument and were prepared for tissue culture, histology, and electron microscopy. Although pars plana vitrectomy offers certain advantages over other methods of biopsy, it does present a danger of extraocular seeding of malignant cells; therefore, it is not recommended in cases with probable intraocular malignancy.
