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]
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.
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.
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 posterior chamber constitutes the remaining five-sixths; its diameter is typically about 24 mm (0.94 in). An area termed the limbus connects the cornea and sclera. The iris is the pigmented circular structure concentrically surrounding the centre of the eye, the pupil, which appears to be black.
The technique he used during the procedure, injecting the sclera with blue dye, is similar to an established method practiced by surgeons who install eye implants. [11] Larratt's wife Rachel underwent a procedure where the surgeon injected small drops of saline to create a fluid-filled pocket between the conjunctiva and the sclera, where he ...
Scleral reinforcement surgery is not presently popular in the United States, and there has been a scarcity of published clinical studies. Donor sclera material is also difficult to acquire and store, and artificial materials are still being tested. This procedure is much more popular in other countries, such as the former Soviet Union and Japan ...
BCEM, also referred to as conjunctival hypermelanosis, complexion-associated melanosis, or racial melanosis, is a non-cancerous lesion of the conjunctiva that is more commonly found in dark-skinned individuals (over 90% of lesions are found in black persons and around 5% in white persons). [1]
