Nanda T, et al. - This paper contemplated the visual hallucinations secondary to topical ocular timolol use. It was determined that the rarity of this side effect and its anecdotal predilection for elderly, Caucasian females with underlying neurological dysfunction, could encompass a yet unknown predisposition or hypersensitivity to beta blocker action, such as blood brain barrier disruption causing increased susceptibility to the medication. A vital, although rare, side effect of this medication was underscored here, which clinicians ought to be aware of especially when using it in elderly patients possibly with coexisting central nervous system (CNS) pathology. This side effect ought to be recognized and appropriately managed for avoiding unnecessary investigations and treatment.
