What are the specific injection points for botulinum toxin in the medial and lateral lower eyelid areas?

The specific injection points for botulinum toxin in the medial and lateral lower eyelid areas are as follows: the medial injection is located in the midpupillary line, 0.5 cm inferior to the eyelid margin, and the lateral injection is midway between the medial point and the lateral canthal line, 1 cm inferior to the eyelid margin.

For botulinum toxin injections in the lower eyelid, two specific points are identified for treatment. The medial injection point is located in the midpupillary line, 0.5 cm below the eyelid margin. The procedure involves inserting the needle subdermally at a medial angle, almost parallel to the skin, and injecting 0.6 units of botulinum toxin to create a wheal. The lateral injection point is situated midway between the medial point and the lateral canthal line, 1 cm below the eyelid margin. During this injection, the orbicularis oculi muscle is contracted, and the needle is angled inferiorly, parallel to the skin, with 0.6 units of botulinum toxin injected subdermally.
