The performance of HIV infection - Eye Performance

1. Choroid, retina and vitreous diseases commonly retinitis, the incidence may be as high as 75%. May be related to CMV, HIV, and toxoplasma infections, etc. It is the main reason of blindness in AIDS patients. In the high-risk groups or HIV infected persons. If unexplained blurred vision, should guard against the disease.
(1), cytomegalovirus (CMV) retinitis: cMv retinitis in AIDS patients is the most common sight-threatening opportunistic infections common in advanced AIDS. The chief complaint of the eyes of a sense of floating debris, unilateral vision loss, and decreased vision. A typical performance is a white cheese-like exudate with retinal hemorrhage, often near large blood vessels in the retina. Tissue section See full-thickness retinal necrosis and swelling of the retina cell nucleus, cytoplasm containing inclusions.

CMV retinitis patients often complain of painless visual impairment, blurred vision or decreased vision defects, more common in monocular. CMV retinitis, mainly through the typical clinical presentation to diagnose. http://www.tcmwell.com

(2), toxoplasma chorioretinitis: Toxoplasma chorioretinitis retinitis than cMV rare, but may be complicated by 20% of AIDS-related toxoplasma encephalitis. With extraocular disease in the spread of pathogens. Showed bilateral, multifocal, necrotizing retinopathy. Can lead to retinal detachment. Vitreous inflammation and anterior uveitis of the more common, but the associated bleeding less than the CMV retinitis.

(3) acute retinal necrosis syndrome: mainly by the herpes simplex virus or varicella-zoster virus causes widespread, bilateral nature, necrotizing retinitis, but is less common, which has been the defining feature of AIDS-related diseases. The disease often have eye disease, associated with keratitis or iritis, many cases recently suffered from at the same time suffering from trigeminal neuralgia, or lips, or herpes simplex, and at the same time there is evidence of viral meningoencephalitis. Ophthalmoscope can be seen surrounding a wide range of off-white retinal damage.

(4), choroiditis, and vitreous inflammation of other causes: in AIDS and HIV infected people have reported cases of syphilitic retinitis, there is no characteristic eye performance, but almost all reported cases of active syphilis were positive serological changes and secondary syphilis of the skin and central nervous system performance. Generally well received intravenous penicillin.

2. Optic neuropathy opportunistic infections and diseases affecting the AR (: or AIDS patient's optic nerve, it can lead to visual impairment or blindness. Optic neuropathy is a common causes of CMV infection. When CMV retinitis affected optic disc, optic papilla, may have decreased vision. At this point we can have other regions of retinitis, or can cause the ball after intraorbital optic nerve and optic nerve inflammation. by the herpes simplex virus or varicella-zoster virus-induced acute retinal necrosis syndrome, can cause optic nerve inflammation, optic neuritis. syphilis phases of AIDS patients can be caused papillitis, optic neuritis or retrobulbar neuritis. Chu Yan retina after optic nerve compression ball blindness caused by cryptococcal meningitis is the most serious eye complications. optic neuropathy by looking for specific causes of infection of other features to determine. But once a serious visual loss, for the cause-specific treatment would be difficult to improve their eyesight. http://www.tcmwell.com

3. Conjunctival and other eye diseases in 10% of AIDS patients have non-specific, non-purulent conjunctivitis, mostly white-limiting, topical application of corticosteroids, sulfa drugs and effective. Other rare causes of conjunctivitis are infected with syphilis and molluscum contagiosum. KS sarcoma invasion and eye, the conjunctiva showed congestion of red nodules, small lesions easily mistaken for a subconjunctival hemorrhage, lymphatic sarcoma of KS can cause periorbital edema. Orbital: KS sarcoma may be associated with ptosis and diplopia.

In the HIV infected persons, syphilis, or varicella-zoster virus infection can cause severe anterior uveitis, the cases of relatively rare. cMV retinitis patients, usually seen mild, asymptomatic uveitis. Keratitis are usually done by varicella-zoster or herpes simplex virus.
