Long-term effect of retrobulbar hematomas on the vision of cynomolgus monkeys


Journal Article

The authors developed an animal model to simulate the conditions that are thought to result in decreased vision following blepharoplasty. The model is based on the premise that impaired vision after blepharoplasty is due to bleeding of orbital fat that increases intraorbital pressure, compromises ocular circulation, and results in permanent retinal and optic nerve damage. Using this model, ocular ischemic periods of variable duration were created by obstructing the central retinal artery and raising intraocular pressure with an intraorbital hematoma. No permanent visual deficits were found by either flash-evoked visual potential or retinal histology. The authors therefore concluded that intraorbital hematomas alone were not sufficient to cause visual loss after blepharoplasty. © 1992 American Society of Plastic Surgeons.
