Extraocular Muscle Botulinum Toxin Type A Injection

Injection can be considered in congenital/sensory nystagmus when short-term relief, preoperative experimental assessment, or those who are not suitable for surgery are needed. The decision depends on the type and severity of nystagmus, previous treatment response, acceptance of temporary effects, overall health and contraindications, and the feasibility of follow-up and reinjection.
