I-Uveitis yisifo lapho ukuvuvukala kwe-choroid kweso (i-uveal tract) kwenzeka. I-membrane ye-vascular iyigobolondo eliphakathi leso, elitholakala ngaphansi kwe-sclera futhi linikeza indawo yokuhlala, ukujwayela nokudla okunomsoco we-retina. Le igobolondo inezingxenye ezintathu: iris, umzimba we-ciliary kanye ne-choroid (empeleni i-choroid).
I-Uveitis, uma kungabikho ukwelashwa okufika ngesikhathi, kungabangela imiphumela embi: i-cataracts, i-glaucoma yesibili, i-lens increment kumfundi, i-edema noma i-retinal detachment, i-opacity ye-vitreous iso, ubumpumputhe obuphelele. Yingakho kubalulekile ukwazi izimpawu zalesi sifo ukuze uthole usizo lwezokwelapha ngesikhathi.
Izimbangela ze-uveitis
Kwezinye izimo, imbangela yalesi sifo ihlala ingacacile. Kukholelwa ukuthi noma yimaphi ama-microorganism angabangela ukuvuvukala, angabangela ukuvuvukala kwe-choroid yeso.
Ngokuvamile, i-uveitis ihlotshaniswa nokutheleleka nge-herpes virus, izifo zesifo sofuba, i-toxoplasmosis, i-syphilis, i-staphylococci, i-streptococci, i-chlamydia (chlamydial uveitis).
Ebusheni, imbangela ye-uveitis ivame ukulimala okuhlukahlukene kwe-choroid. Futhi, i-uveitis ingahlotshaniswa nezinqubo zokuvuvukala zesimiso emzimbeni onesifo samathambo (i-rheumatoid uveitis), i-sarcoidosis, isifo sika-Bechterew, isifo sika-Reiter's, isifo sokulonda i-ulcerative, nezinye.
Inqubo yokuvuvukala emgqeni we-uveal ivame ukuhlotshaniswa nokufakela izakhi zofuzo, ukwehla kwegciwane lokuzivikela, isisindo somzimba.
Ukuhlukaniswa kwe-uveitis
Ngokusho kwenkambo yezokwelapha:
- i-uveitis enzima (isikhathi esingaphansi kwezinyanga ezintathu);
- i-uveitis engapheli (izinyanga ezingaphezu kwezinyanga ezintathu);
- UVAISIT okuphindaphindiwe (ukukhuphuka kwenzeka emva kwesikhathi sokungabikho kokuvuvukala ngaphandle kokwelashwa).
Ngokwezifiso:
- i-anterior uveitis (iridocyclitis) - umzimba we-iris ne-ciliary uvuvuka;
- i-uveitis ye-posterior (i-choroiditis, i-chorioretinitis) - i-choroid, i-retina ne-nertic optic iyathinteka;
- i-uveitis yomzimba-ukuvuvukala komzimba we-ciliary, kanye nezingxenye zangaphakathi ze-choroid, i-vitreous ne-retina;
- I-Panovitis - i-membrane ye-vascular ye-iso igcwele ngokuphelele.
Kukhona futhi okugxilwe futhi okusabalalisa uveitis, futhi ngokusho kwesithombe sokuziphatha sokuvuvukala - i-granulomatous non-granulomatous.
Izimpawu ze-uveitis kuye ngokuthi indawo yendawo
Izimpawu eziyinhloko ze-uveitis yangaphakathi yilezi:
- i-photophobia;
- ubuhlungu emehlweni;
- ubomvu;
- ukuwohloka kombono ;
- ukwakheka kweqhwa ngokweqile;
- ukunciphisa umfundi.
Izimpawu ezingenhla zihambisana kakhulu nesimo esibi salolu hlobo lwesifo. Ukugula okungapheli kwe-anterior uveitis ezimweni eziningi kunamabonakaliso angabonakali, ngaphandle kokuzwa "kwezinmpukane" phambi kwamehlo nokubomvu okuncane.
Izimpawu zohlobo lwe-postitis oluphansi luhlanganisa:
- ukubukeka kwe "izimpukane" phambi kwamehlo;
- "Inkungu", "shroud" phambi kwamehlo;
- ukuhlanekezela okubonakalayo kwezinto;
- ukwehla kancane kancane embonweni.
Njengomthetho, izibonakaliso ze-uveitis e-posterior zibonakaliswa ekugcineni. Ngoba lolu hlobo lwesifo aluvamile ukubomvu kwamehlo nobuhlungu.
Uhlobo lwe-peripheral lwe-uveitis lubonakala ngokubonakaliswa okulandelayo:
- ukunqotshwa kokulinganisa kokubili amehlo;
- ukubukeka kwe "izimpukane" kanye "namabala" phambi kwamehlo;
- ukuwohloka kwezinto ezibonakalayo;
- i-strabismus
I-Panoveitis ayivamile. Loluhlobo lwesifo luhlanganisa izimpawu ze-uveitis zangaphakathi, ezisemkhatsini naphakathi kwe-postitis.
Ukuxilongwa kwe-uveitis
Ukuze ukuxilongwa kudinga ukuhlolwa ngokucophelela kwamehlo ngesibani sokuqhafaza ne-ophthalmoscope, ukulinganisa kokucindezelwa kwe-intraocular. Ukukhipha noma ukuqinisekisa ukuthi kukhona isifo sesistimu, ezinye izinhlobo zocwaningo (isibonelo, ukuhlolwa kwegazi) zenziwa.
