We report a case of a 69-year-old gentleman who developed an acutely painful eye with loss of visual acuity whilst on the critical care unit. He was admitted three days previously with an infective exacerbation of chronic obstructive pulmonary disease requiring invasive mechanical ventilation. In addition, he received intravenous antibiotics, steroids, nebulised bronchodilators and intravenous aminophylline, together with noradrenaline for blood pressure support. On development of visual symptoms, an emergency ophthalmology review diagnosed acute angle closure glaucoma. Treatment with pilocarpine eye drops, intravenous acetazolamide and bilateral YAG laser iridotomies provided immediate symptom relief and he went on to make an excellent recovery. Acute angle closure glaucoma is a potentially devastating ophthalmic emergency. Critical care patients are at particular risk for the development of this condition due to the use of predisposing medications, such as sympathomimetics and beta agonists. Sedated patients also run a risk of delayed diagnosis so a high index of suspicion is required.
