Role of skeletal scintigraphy in advanced retinoblastomas.

Purpose: To document the incidence of skeletal metastases exclusively in advanced cases of retinoblastoma and to rationalize the use of preoperative skeletal scintigraphy in such patients.

Material And Methods: Preoperative bone scans of 36 consecutive patients with advanced retinoblastoma who underwent skeletal scintigraphy during 1998 to 2003 were analyzed retrospectively. Bone scans were classified as: Grade 1 (high probability scan for skeletal metastases), Grade 2 (equivocal malignant or benign abnormalities), or Grade 3 (normal or certainly benign lesions).

Transpupillary thermotherapy in subfoveal choroidal neovascular membrane secondary to age-related macular degeneration.

Purpose: To report our initial experience in the treatment of subfoveal choroidal neovascular membrane, secondary to age-related macular degeneration (AMD) by transpupillary thermotherapy (TTT).

Methods: Fifty consecutive patients with subfoveal choroidal neovascularisation (CNV) secondary to AMD, were included in the study. The parameters assessed before the TTT were visual acuity by ETDRS chart, scotoma score by Amsler grid chart, reading speed, fundus examination by direct and indirect ophthalmoscope as well as +90 Diopter lens followed by digital fundus photography and fluorescein angiography (FA).

Intraocular live cysticercus larva.

Ocular cysticercosis is one of the most common parasitic infections of the eye in humans. Although the adult pork tapeworm, Taenia solium, resides in the lumen of the intestine, the only structural element of an adult worm is usually found within a tissue cyst in the eye, its adenexa, or other places in the body with a single invaginated scolex. An unusual case is described in which a 13- to 14-mm live cysticercus larva was found, removed from the eye, and confirmed by histopathologic examination.
