I-Uveitis yisifo apho ukuvuvukala kwe-choroid yelihlo (i-tract of tract) kwenzeka. I-membrane ye-vascular iyigobolondo eliphakathi kweso, elisezantsi kwe-sclera kwaye linikeza indawo yokuhlala, ukulungelelaniswa kunye nesondlo se-retina. Le ngqungquthela inamalungu amathathu: iris, umzimba we-ciliary kunye ne-choroid (ngokwenene i-choroid).
I-Uveitis, ngokungabikho kwonyango olufike ngexesha, kunokukhokelela kwimiphumo emibi: i-cataracts, i-glaucoma yesibini, i-lens increment kumfundi, i-edema okanye i-retinal detachment, i-opacity ye-vitreous iso, i-blindness ephelele. Yingakho kubalulekile ukwazi izibonakaliso zesi sifo ukuze ufune uncedo lwezonyango ngexesha.
Izizathu ze-uveitis
Kwezinye iimeko, imbangela yesi sifo ihlala ingacacanga. Kukholelwa ukuba nayiphi na i-microorganism engabangela ukuvuvukala, kunokubangela ukuvuvukala kwe-choroid yesiso.
Ngokugqithiseleyo, i-uveitis inxulumene nosulelo lweentsholongwane ze-herpes, izifo zesifo sofuba, i-toxoplasmosis, i-syphilis, i-staphylococci, i-streptococci, i-chlamydia (chlamydial uveitis).
Ubuntwaneni, imbangela ye-uveitis ivame ukuxhatshazwa kwezinto ezihlukahlukeneyo. Kwakhona, u-uveitis unokudibaniswa neenkqubo zokuvuvukala emzimbeni nge-rheumatoid arthritis (i-rheumatoid uveitis), i-sarcoidosis, isifo sikaBechterew, isifo sikaReiter, isifo se-ulcerative colitis kunye nabanye.
Inkqubo yokuvuvukala kwiphepha elivakalayo lidla ngokuxhomekeke kwimimiselo yezinto eziphilayo, ukuhla kwe-immununity, isifo esiyingozi.
Ukwahlula kwe-uveitis
Ngokutsho kwekliniki:
- i-uveitis enzima (ixesha elingaphantsi kweenyanga ezintathu);
- u uveitis ongapheliyo (ngaphezu kweenyanga ezintathu);
- i-uveitis ephindaphindiweyo (ukukhushulwa kwenzeka emva kwexesha lokungabikho kwesifo ngaphandle kokunyanga).
Ngendawo:
- i-uveitis yangaphakathi (iridocyclitis) - umzimba we-iris kunye ne-ciliary utshabalala;
- i-uveitis ye-postitis (choroiditis, chorioretinitis) - i-choroid, i-retina kunye ne-optic nerve ichaphazelekayo;
- i-uveitis ye-peripheral-ukuvuvukala komzimba we-ciliary, kunye neendawo zangaphambili ze-choroid, i-vitreous ne-retina;
- I-Panovitis - i-membrane ye-vascular yelihlo ichithwe ngokupheleleyo.
Kukho kwakhona kugxininisa kwaye kufaka i-uveitis, kwaye ngokubhekiselele kumfanekiso wendlela yokuvuvukala - i-granulomatous non-granulomatous.
Iimpawu ze-uveitis ngokuxhomekeka kwendawo
Imiqondiso ephambili ye-uveitis yangaphakathi yile:
- photophobia;
- intlungu emehlweni;
- ubomvu;
- ukuwohloka kombono ;
- ukwakheka kweqabunga;
- ukunciphisa umfundi.
Izimpawu ezingentla zihambelana nefomu elibi lelo hlobo lwesifo. Iimeko ezininzi ezingapheliyo kwi-uveitis kumaxesha amaninzi ziphantse zibonakaliswe zibonakaliso, ngaphandle kovakalelo "lweempukane" phambi kwamehlo kunye nokukhishwa kancinci.
Izibonakaliso ze-uveitis ephezulu ziquka:
- ukubonakala "kweempukane" phambi kwamehlo;
- "Inkungu", "igubungele" phambi kwamehlo;
- ukuphazamiseka okubonakalayo kwezinto;
- kwehla ngokuthe ngcembe kwimbono.
Njengomthetho, iimpawu ze-uveitis yangasemva zibonakaliswe kungekudala. Kuba olu hlobo lwesifo alubonakali kubomvu kwamehlo nangentlungu.
Uhlobo lwe-peripheral ye-uveitis lubonakaliswe ngokubonakaliswa okulandelayo:
- ukutshatyalaliswa ngokulinganayo kwamehlo omabili;
- ukubonakala kwe "iimpukane" kunye "namabala" phambi kwamehlo;
- ukuwohloka kwezinto ezibonakalayo;
- i-strabismus
I-Panoveitis ayifumaneki. Olu hlobo lwesifo ludibanisa iimpawu zangaphambili, eziphakathi kunye ne-posterior uveitis.
Ukuxilongwa kwe-uveitis
Kuba ukuxilongwa kuyadingeka ukuhlolwa ngokucophelela kwamehlo kunye nesibane sokutshatyalaliswa kunye ne-ophthalmoscope, ukulinganisa ukunyanzeliswa kwe-intraocular. Ukukhuphela okanye ukuqinisekisa ubukho besifo sesistim, ezinye iintlobo zophando (umzekelo, ukuhlolwa kwegazi) kwenziwa.
