Hyperaemia of the superficial bulbar conjunctiva blood vessels. In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells, stratified columnar ...
Subconjunctival bleeding, also known as subconjunctival hemorrhage or subconjunctival haemorrhage, is bleeding from a small blood vessel over the whites of the eye. It results in a red spot in the white of the eye. [1] There is generally little to no pain and vision is not affected. [2][3] Generally only one eye is affected.
Ophthalmology. A red eye is an eye that appears red due to illness or injury. It is usually injection and prominence of the superficial blood vessels of the conjunctiva, which may be caused by disorders of these or adjacent structures. Conjunctivitis and subconjunctival hemorrhage are two of the less serious but more common causes.
Blood vessels of the eyelids, front view. An eyelid (/ ˈaɪ.lɪd / EYE-lid) is a thin fold of skin that covers and protects an eye. The levator palpebrae superioris muscle retracts the eyelid, exposing the cornea to the outside, giving vision. This can be either voluntarily or involuntarily.
3–6 million per year (US) [ 1 ][ 3 ] Conjunctivitis, also known as pink eye, [ 4 ] is inflammation of the outermost layer of the white part of the eye and the inner surface of the eyelid. [ 5 ] It makes the eye appear pink or reddish. [ 1 ] Pain, burning, scratchiness, or itchiness may occur. [ 1 ] The affected eye may have increased tears or ...
Frequency. 1% to 33% [7] A pterygium of the eye (pl.: pterygia or pterygiums, also called surfer's eye) is a pinkish, roughly triangular tissue growth of the conjunctiva onto the cornea of the eye. [2] It typically starts on the cornea near the nose. [3] It may slowly grow but rarely grows so large that it covers the pupil and impairs vision. [2]
Iris, front view. The anterior ciliary arteries are seven arteries in each eye-socket that arise from muscular branches of the ophthalmic artery and supply the conjunctiva, sclera, rectus muscles, and the ciliary body. The arteries end by anastomosing with branches of the long posterior ciliary arteries to form the circulus arteriosus major.
pɪˈtiːkɪə. Specialty. Rheumatology. A petechia (/ pɪˈtiːkiə /; [1] pl.: petechiae) is a small red or purple spot (≤4 mm in diameter) that can appear on the skin, conjunctiva, retina, and mucous membranes which is caused by haemorrhage of capillaries. [2][3] The word is derived from Italian petecchia ' freckle ', of obscure origin. [1]
