Which condition presents with sudden onset of eye pain, blurred vision, headache, nausea/vomiting and halos around lights?

Explanation:
This presentation is classic for acute angle-closure glaucoma. When the drainage angle of the eye closes abruptly, intraocular pressure rises quickly. The result is a painful, red eye with blurry vision, headache, and systemic symptoms such as nausea and vomiting. Halos around lights occur because corneal edema from the high pressure scatters light, creating those rings. Understanding why this fits better than other options helps: acute conjunctivitis tends to itch and tear with discharge, not the sudden severe pain and halos; corneal edema can cause halos but usually has a different context or history; retinal detachment presents with painless, progressive vision loss described as a curtain coming down rather than halos, and it lacks the acute systemic symptoms. This is an emergency. Management focuses on rapidly lowering intraocular pressure and urgent ophthalmology involvement. In the emergency setting, start IOP-lowering therapy (eg, acetazolamide to reduce production, plus topical agents such as a beta-blocker and possibly an alpha-agonist). After pressure begins to fall, a pupil-constricting agent may be used to help open the angle (pilocarpine). Provide analgesia and antiemetics as needed, and avoid medications that dilate the pupil. Prompt definitive treatment by an eye specialist is essential to prevent optic nerve damage.
