Most of the rare bilateral acute angle closure (AAC) cases are precipitated by systemic factors, such as drug intake, snake bite or general anaesthesia. We present a case of simultaneous bilateral AAC in a middle-aged male, precipitated by the use of medication for flu, containing an alpha-1 adrenergic receptor agonist and an anticholinergic agent. In our case, axial length was shorter, anterior chamber depth was narrower, and the lens was thicker than normal, including the patient within the risk group for AAC. In this circumstance, drugs acted as triggers. Case description and evolution following treatment are completed with the discussion of mechanisms involved in triggering bilateral AAC in predisposed patients, as emerging from literature. This case report brings up the risk of bilateral AAC in patients at risk, of which ophthalmologists, physicians of other specialties and patients should be aware of.
