Abstract:
An analysis of the probable aetiology of 222 cases of uveitis. In order of frequency the aetiology was: infectious focis 31%, rheumatism 28%, tuberculosis 7.6%, streptococci 4%, viral 3.6%, rickettsia 1.3%, syphilis, brucellosis in 0.5%. In 22.1% of cases the aetiology was not established. In young subjects the majority consisted of bacterial and viral infections particularly streptococcal. In adults the most frequent aetiology was rheumatic and in the elderly foci of infection.

The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
