The classic presentation of a corneal ulcer includes severe eye pain, a foreign body sensation, photophobia, and a visible corneal infiltrate or opacity (a white spot). Acute angle-closure glaucoma also presents with severe pain, but its key features are a hazy cornea, a fixed mid-dilated pupil, and often nausea and vomiting. Retinal detachment is typically painless and characterized by photopsia (flashes of light), floaters, and a curtain-like visual field defect. Conjunctivitis causes redness and discharge but typically does not involve severe pain or a corneal opacity.
