Case Reports
Monocular blindness: a complication of intraoperative positioning in posterior cervical spine surgery.
Postoperative visual loss after spine surgery is a rare but devastating complication. Although uncommon, reports of postoperative blindness are documented in spine and cardiopulmonary bypass surgeries with an incidence varying between 0.05 percent and one percent. ⋯ Unfortunately, he developed unilateral blindness in his right eye. The potential aetiological factors and ways to prevent this disastrous complication are discussed.

Retinoblastomas of the eye are a cause of childhood blindness and have a high rate of mortality, as well as a hereditary mode of transmission. Other conditions that mimic retinoblastomas are known as pseudoretinoblastomas, and are managed differently. Although pseudoretinoblastoma and the accuracy of retinoblastoma diagnosis have been reviewed in Caucasian patients, published studies in Asian patients are lacking. The purpose of this article is to report our experience with pseudoretinoblastomas in two major ophthalmological centres in Asia. ⋯ Although our sample size is small, the percentage of confirmed retinoblastomas was found to be only slightly higher than that found in western countries. Our findings are consistent with their findings that Coat's disease and presumed ocular toxocariasis are the more common causes of pseudoretinoblastoma.
