A 60-year-old man presents with a red, painful eye on the right side and decreased vision. He had cataract surgery in the affected eye 4 days earlier but noted no symptoms until that morning. His visual acuity is light perception only in the right eye and 6/9 in the left eye. Intraocular pressures are 28 and 14 mm Hg in the right and left eyes, respectively. Examination of the anterior chamber and lens reveals marked chemosis, conjunctival injection, and a small hypopyon. Upon direct ophthalmoscopy, a diffuse hazy vitreous is discerned.
The most likely diagnosis is
-
Bacterial conjunctivitis
-
Acute angle-closure glaucoma
-
Corneal abrasion
-
Postoperative endophthalmitis
