Anatomy Cat Third Eyelid
The third eyelid or the nictitating membrane is a modified form of conjunctival fold in the medial canthus part of the eye in almost all domestic animals.
Conjunctiva – The conjunctiva is divided into two parts, the bulbar surface, and the palpebral surface. The bulbar surface is the concave side facing the eyeball while the palpebral is the convex side that faces the eyelids.
Lymphoid Tissue – The lymphoid tissue is the diffused form of lymphoid follicles. It is located under the bulbar conjunctival. The cobblestone appearance of the surface is known as due to the lymphoid tissue.
Cartilage – The tough T-shaped hyaline cartilage is responsible for supporting the third eyelid. The arms of the cartilage tissue are parallel to the margins of the eyelid. The stem of the cartilage extends up to the medial canthus and is embedded in the gland of the third eyelid.
The Third Eye Lid Gland – The gland produces about 30% to 40% of the aqueous solution of the eye.
Vasculature – It is a small artery that enters at the base of the third eyelid.
Smooth Muscles – the smooth muscles are present at the base of the eyelid.
