Choice (D) is the correct answer. Acute angle-closure glaucoma presents as a red, painful eye with associated headache, nausea, and vomiting. Visual changes include blurry vision with halos around objects. Acute angle-closure glaucoma is caused by a sudden rise in intraocular pressure (IOP). In susceptible patients, mid-dilation of the pupil results in aqueous outflow obstruction leading to an acute rise in IOP. The other choices are incorrect.
