An eccentric presentation of transient bilateral mydriasis after botulinum toxin injection: A case report.

Introduction: Botulinum toxin (Botox) can be used to manage strabismus due to its efficacy in inducing muscle paralysis by blocking acetylcholine release. Botox is an important treatment for many conditions in ophthalmology; however, clinicians must be aware of its potential complications, such as mydriasis. Mydriasis is defined as dilation in the pupils, and it can be divided into two subsets: transient and persistent mydriasis.
