Narrow angle glaucoma is an ocular emergency. In such cases, there is an obstruction in the drainage of the aqueous fluid due to a narrowing of the angle between the base of the iris and the cornea. The symptoms can be a sudden, painful red eye, nausea, vomiting, headache, and visual halos.
According to a study in PubMed, narrow angle glaucaoma, also known as acute angle glaucoma, can be a rare, but potential, side effect of general anesthesia. Researcher cite possible risk factors: the drugs ephedrine and nefopam administration and the prone surgical position (lying on the belly during the procedure).

Scientists have determined that glaucoma patients who have damage to both hemifields (half of the visual field) of their eye will experience more rapid progression of the disease than patients who have damage to a single hemifield.
The study, published in the September 2009 journal Archives of Ophthalmology, reviews data from 205 patients. 79 were found with an initial superior defect, 61 with an initial inferior defect, and 65 with both hemifields affected.
Analysis showed significantly higher baseline intraocular pressure and thinner central corneal thickness in patients with initial damage to both hemifields.
The study authors concluded that initial damage to both hemifields increases the risk of glaucoma progression, and that doctors should consider more aggressive therapy for these patients.
