Localization of glial fibrillary acidic protein in retinal astrocytoma: an immunohistochemical study.

Glial fibrillary acidic protein (GFA) is found in glial filaments, and is specific for reactive or neoplastic astrocytes and ependyma. Using a commercially available antibody to GFA protein, a retinal neoplasm from a patient with neurofibromatosis is intensely stained with the brown immunoperoxidase reaction product. Rather than the less specific phosphotungstic acid hematoxylin (PTAH) or Holzer's stain, antibody to GFAP protein is a relatively rapid, simple, and reliable immunohistochemical technique for formalin-fixed and paraffin-embedded tissue.

Chorio-retinal resection of a neoplasm from the human eye.

An epithelioma was removed from the iris and ciliary body of a six-year-old girl by a partial irido-cyclectomy. Three months later recurrence of the tumour was seen in the equatorial zone of the fundus. Three weeks after application of transscleral cryotherapy around the neoplasm, a chorio-retinal resection of the tumour area in the fundus was performed. The postoperative healing was satisfactory. Re-examination 16 months later revealed a healthy eye. The results indicate that a circumscribed tumour can successfully be resected from the fundus.

Clinical cases in AIDS. 2.

As the human immunodeficiency virus (HIV) epidemic continues, there are increasing numbers of patients with HIV-related disease. Those doctors studying for the MRCP exam will need to be familiar with the common manifestations of HIV infection and acquired immunodeficiency syndrome.

Central retinal artery occlusion.

Injecting steroid crystals into orbital inflammatory lesions produces a prolonged, high level of drug activity at the target tissue. This technique appears helpful in controlling orbital inflammations in problem cases while reducing the chance of steroid related systemic side effects. We report a patient who experienced central retinal artery occlusion from steroid particles injected into an orbit inflammatory mass. The mechanism of this complication and methods to reduce the chance of central retinal artery embolization are discussed.
