Conjunctivitis. Symptoms

 Injection (redness) of a conjunctiva on one or both eyes should be obvious, but can be rather soft. Except in an obvious purulent or toxicant/chemical conjunctivitis, the slit lamp (biomicroscope) is necessary to have any confidence of the diagnosis. Examination predpljusnevoj conjunctivas is usually more diagnostic than a bulbar conjunctiva.

 The allergic conjunctivitis shows an acyanotic watery swelling or a chemosis and sometimes the whole century, is frequent with viscous, not purulent mucoid allocation. There is a variable redness.

 The virus conjunctivitis usually known as "a pink eye", shows fine diffuse porozovenie conjunctivas which easily is accepted for ' ciliary injection ' an iritis, but there are usually confirming symptoms on biomicroscopies, especially numerous lymphoid follicles on predpljusnevoj to a conjunctiva, and sometimes punctate a keratitis.

 The purulent bacteriemic conjunctivitis shows an opaque purulent discharge, very red eye, and on biomicroscopy there are numerous white cells and the desquamated epithelial cells noted in ' to a ditch of a disrupture ' along edge of a century. predpljusnevaja a conjunctiva - a velvet redness and not especially follicular. Not purulent infections can show only the soft injection and to be difficult to diagnose. The cicatrization predpljusnevoj conjunctivas is casually noted in chronic infections, especially in trachoma.

 The irritable or toxicant conjunctivitis shows first of all noted redness. If should to spill a wound, it often is present only at lower conjunctival bag. With a small amount of chemical substances - first of all with caustic alkalis, such as gidroksid sodium - the conjunctiva necrosis a white eye because of the vascular cover accompanied by tearing away nekroticheskh of masses of a dead epithelium can be deceptive. It, possibly, will be bound to a sign of a slit lamp of a previous uveitis.
