Moraxella lacunata was first described independently by Victor Morax (1896) and Theodor Axenfeld (1897), hence the alternate name "Morax-Axenfeld diplobacilli" and the name of eye infection in humans is sometimes called Morax-Axenfeld conjunctivitis.
Conjunctivitis due to common pus-producing bacteria causes marked grittiness or irritation and a stringy, opaque, greyish or yellowish discharge that may cause the lids to stick together, especially after sleep. Severe crusting of the infected eye and the surrounding skin may also occur.
Uveitis may be an immune response to fight an infection caused by an organism in the eye. They are less common than non-infectious causes and require antimicrobial/ viral/ parasitic treatment in addition to inflammatory control. Infectious causes in order of global burden include: Subretinal abscess in tubercular posterior uveitis. bartonellosis
"Conjunctivitis basically means inflammation of the conjunctiva, which is the clear part that covers the white part of the eyes," says Dr. Sumitra Khandelwal, an associate professor of ...
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 ...
Types include sympathetic ophthalmia (inflammation of both eyes following trauma to one eye), gonococcal ophthalmia, trachoma or "Egyptian" ophthalmia, ophthalmia neonatorum (a conjunctivitis [3] of the newborn due to either of the two previous pathogens), photophthalmia and actinic conjunctivitis (inflammation resulting from prolonged exposure to ultraviolet rays), and others.
Short-term over-exposure can cause snow blindness, which is analogous to sunburn of the cornea, or can cause solar retinopathy, which is long-lasting retinal damage and vision impairment from sungazing. [52] [53] Frequent exposure to the sun can cause yellow non-cancerous bumps on the middle part of the sclera of the eye, called pingueculae. It ...
The epidemic nature of this bacteria has been seen in the high frequency of “control” subjects from the affected areas of Brazil that have or had recently had conjunctivitis. These control subjects did not develop Brazilian Purpuric Fever, and therefore were probably not carrying the more dangerous BPF clone of H. influenzae biogroup aegyptius.
