How to monitor eye health and safety while taking Vigabatrin (vigabatrin)

Vigabatrin (Vigabatrin) is an antiepileptic drug used to treat refractory epilepsy and infantile spasms. Although it is effective in controlling epileptic seizures, long-term use may cause retinal toxicity, leading to visual field defects or even permanent visual impairment. Therefore, monitoring the patient's eye health and safety is an important step during medication.

First, a comprehensive eye examination, including vision testing, visual field examination, and fundus examination, should be performed before treatment begins to establish baseline data. These examinations can help doctors understand the patient's eye condition and identify any abnormal changes caused by medications during subsequent treatment. For pediatric patients, visual field testing may be difficult to perform, and appropriate testing methods need to be selected based on age and cooperation.

Secondly, regular ophthalmological follow-up should be performed during the medication period. It is usually recommended to review visual field and retinal function every 3 to 6 months. Monitoring content includes visual field range, electroretinogram (ERG) and other examinations to detect early signs of retinal damage in a timely manner. If visual field defects or other abnormalities occur, doctors should evaluate the risks and efficacy of the medication and consider adjusting the dose or discontinuing the medication.

Finally, patients and family members also need to strengthen their awareness of self-monitoring during medication, pay attention to any changes in vision, such as narrowing of the field of vision, blurred vision, or dark shadows in front of the eyes and other abnormal symptoms, and should report to the doctor in a timely manner. Through multi-party collaboration and strict monitoring of eye health, the occurrence of Vigabatrin-related retinal toxicity can be minimized and the safe use of the drug can be ensured for patients.
