The potential ocular side effect of certain ADHD medications that is being highlighted is angle closure. Stimulant medications, commonly prescribed for attention-deficit/hyperactivity disorder (ADHD), can lead to mydriasis, or dilation of the pupils, as a side effect. In individuals with pre-existing narrow angles, this pupil dilation can precipitate an acute angle closure glaucoma attack, which is a medical emergency involving a sudden rise in intraocular pressure.

While other options like blurred vision, night blindness, and diplopia can occur as side effects of various medications, angle closure is particularly relevant in the context of ADHD medications due to their pharmacological effects on the pupil and the potential for complications in patients with certain ocular anatomies. This highlights the importance of reviewing a patient's ocular history before starting stimulant therapy for ADHD.
