    Endocryotherapy shows potential for hemangioblastoma

    Take-home: Endocryotherapy is a good treatment option for patients with larger retinal angiomatous tumors.

    Transvitreal endocryotherapy can be a reasonable option for the treatment of larger retinal angiomatous tumors.

    Colin A. McCannel, MD, FACS, FRCS(C), professor of clinical ophthalmology and medical director, Stein Eye Institute, Department of Ophthalmology, David Geffen School of Medicine at UCLA, outlined how endocryotherapy can be a treatment for retinal hemangioblastoma.

    He presented the case of a 25-year-old, white female patient with a peripheral hemangioblastoma.

    “External cryotherapy had been tried on several occasions by the referring ophthalmologist without achieving tumor control,” Dr. McCannel said.

    Dr. McCannel decided to treat the patient with a vitrectomy and internal cryotherapy. The patient presented with an angioma and dilated arcade vessels that lead up to it.

    After enlargement of the sclerotomy, the hemangioblastoma was treated with a freeze-thaw-freeze technique. Dr. McCannel briefly discussed follow-ups at 13 months and 23 months, noting that the patient had an excellent result without retinal detachment development, either serous or rhegmatogenous. Furthermore, the dilated vessels had returned to normal size, and the angioma was reduced to a small fibrotic mass.
