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.
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 epithelium and stratified cuboidal epithelium (depending on the ...
The episclera is the outermost layer of the sclera (the white of the eye). [1] It is composed of loose, fibrous, elastic tissue and attaches to Tenon's capsule. [1]A vascular plexus is found between the bulbar conjunctiva and the sclera consisting of two layers of vessels, the superficial episcleral vessels and the deep episcleral vessels.
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
Using the subconjunctival injection bypasses the fatty layers of the bulbous conjunctiva and putting medications adjacent to sclera that is permeable to water, this will increase the penetration of the water-soluble drug into the eye. [1]
The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera. It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium. The conjunctiva is basically transparent, and the white colour we see is actually sclera.
Conjunctival infection, or redness of the sclera surrounding the iris and pupil. Eye irritation has been defined as "the magnitude of any stinging, scratching, burning, or other irritating sensation from the eye". [61] It is a common problem experienced by people of all ages.
The diffuse type of episcleritis may be less painful than the nodular type. Sometimes, small nodules are present within the episclera, which move slightly over the sclera with gentle pressure. [5] Discharge is absent with episcleritis, and vision is unaffected. [5] Patients with episcleritis experience far less photophobia than patients with ...
