Author information

  • 1Department of Ophthalmology, Aichi Medical University, Nagakute, Aichi, Japan.


The anatomy of the lateral canthus is analogous to that of the medial canthus, but with a less defined structure. Although the lateral canthal tendon occupies the major part of the lateral canthal anatomy, the lateral rectus capsulopalpebral fascia and other structures also play a significant role. Appropriate comprehension and consideration of the lateral canthal anatomy enable safe and effective performance in the lateral canthal surgeries. In this review, we present the lateral canthal anatomy along with updated topics. We discuss the lateral canthal tendon, lateral orbital thickening, lateral palpebral raphe, lateral canthal muscle, lateral rectus capsulopalpebral fascia, lateral check ligament, lateral retinaculum, and orbitomalar ligament.
