The tarsi (sg.: tarsus) or tarsal plates are two comparatively thick, elongated plates of dense connective tissue, about 10 mm (0.39 in) in length for the upper eyelid and 5 mm for the lower eyelid; one is found in each eyelid, and contributes to its form and support.

Jul 11, 2019 · The tarsal plates of the eyelids are comprised of dense connective tissue. They are attached to the periosteum horizontally via the medial and lateral canthal tendons.

Oct 25, 2020 · The tarsal plates are located deep to the palpebral region of the orbicularis oculi muscle. There are two plates; the superior tarsus (upper eyelid) and inferior tarsus (lower eyelid). They act to form the scaffolding of the eyelid, and are composed of dense connective tissue.

May 24, 2024 · Like elastic in the waistband of stretchy clothing, the tarsal plates help keep your eyelids snugly against your eye surface. The muscles and other connective tissue around your eye can tighten and tug on the tarsal plates, helping move your eyelids up and down.

Tarsal plate is a dense fibrous tissue plate acting as a skeleton of the eyelid giving it shape and firmness. Height of the tarsus is about 10-11mm and that of Lower tarsus is 4 – 5 mm.

Oct 30, 2023 · The tarsal plates are the main scaffolding of the eyelids and are made of dense connective tissue. They also contain the eyelash follicles and the tarsal glands (otherwise known as Meibomian glands) secreting an oily substance slowing the evaporation of the eye’s tear film.

Jan 22, 2025 · The tarsal glands, also known as the Meibomian glands, are specialized sebaceous glands located within the eyelids. These elongated glands are responsible for producing an oily secretion that plays a critical role in maintaining the stability of the tear film and preventing tear evaporation.

Dec 22, 2022 · There are seven extraocular muscles – the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. Functionally, they can be divided into two groups: Responsible for eye movement – Recti and oblique muscles.

Feb 6, 2025 · The tarsal conjunctiva is the thin, transparent membrane that lines the inside of the eyelids and covers the white part of the eye. It is made up of a layer of epithelial cells and contains blood vessels, glands, and immune cells.
