Does preemptive low-dose of ketamine effective on anesthetic consumption , perioperative analgesic requirement and postoperative pain , nausea and vomiting in painful ophthalmic surgery?
This study demonstrates that a low dose administration of ketamine during anesthesia induction in retinal detachment, strabismus, and keratoplasty surgery improves the extubation time but have no effect on postoperative pain, nausea and vomiting, and perioperative additional analgesic requirements.
Patients with amblyopia and strabismus could see better with only one eye instead of both eyes. This could be related to inhibition of the binocular function of the brain by the misaligned amblyopic eye.
