Transmission of viruses through corneal transplantation.

Transmission of viruses through transplantation has become a major concern for surgeons and tissue banks. Keratoplasty has been the first transplantation procedure in which transmission of a virus from the donor to the recipient has been proven, and recently, herpes has been suggested as a transmittable disease via corneal transplantation. In this article we review the history of viral transmission through transplantation, especially focusing on keratoplasty, and develop the recent updates on transmission of HSV through corneal grafting, its implications for surgeons and eye banks, and further insights into viral security in eye banks.

Decrease of intraocular pressure after fat-removal orbital decompression in Graves disease.

PURPOSE: To address the efficacy of fat-removal orbital decompression to reduce intraocular pressure in patients with Graves disease. METHODS: This cohort study included 64 eyes of 39 patients with Graves disease. Thirteen men and 36 women, with a mean age of 52.5 years (range, 27 to 80 years), underwent fat-removal orbital decompression. Intraocular pressure (applanation) and proptosis (Hertel exophthalmometry) were prospectively investigated before surgery and 1 week and 6 months after surgery. RESULTS: The volume of resected fat was 6.4+/- 4.5 (3 to 12) ml. The intraocular pressure in primary position decreased from 19.3+/- 4.4 mm Hg to 17.0+/- 2.9 mm Hg at 1 week (p<0.001) and 15.9+/- 3.7 mm Hg at 6 months (p<0.001). Mean proptosis dropped from 24.3+/- 2.5 mm before surgery to 19.9+/-3.0 mm at 1 week (p<0.01), and 19.9+/-3.1 mm at 6 months (p<0.01). Intraocular pressure decrease neither correlated to the volume of resected fat nor to proptosis reduction. CONCLUSIONS: Fat removal reduces intraocular pressure in patients with Graves disease, with no correlation to the volume of resected fat.
