Medial Palpebral Commissure, Anterior View

Description

Framed in an anterior facial view, the medial palpebral commissure (medial canthus) is identified bilaterally at the junction of the upper and lower eyelids. Medial to the gray line and lash margin, the lacrimal caruncle sits within the lacus lacrimalis, with the plica semilunaris just lateral to it at the medial conjunctival fornix. Along the posterior lid margin near the canthus, the superior and inferior lacrimal puncta align with the canaliculi, which course medially toward the lacrimal sac in the lacrimal fossa. Blue arrows direct attention to the inner canthal landmarks. Medial canthal anatomy matters when you are localizing epiphora, canaliculitis, or acute dacryocystitis, where tenderness and swelling often track to the lacrimal sac region just inferomedial to the commissure. For oculoplastic planning, the relationship of the commissure to the medial palpebral ligament and the puncta sets the limits for medial canthopexy, laceration repair involving the canaliculus, and blepharoplasty markings that must preserve the tear drainage pathway. Small distances here change function. Use this asset in head and neck anatomy teaching blocks, ophthalmology clerkship materials, and surgical texts covering lacrimal drainage disorders and eyelid trauma repair, where a realistic skin texture and clear medial canthus labeling support bedside correlation. It also suits patient-facing diagrams for explaining punctal occlusion, canalicular stenting, or dacryocystorhinostomy consultations in an outpatient eye clinic.
