I-Uveitis ukuvuvukala kwe-iris kanye/noma i-choroid/retina esweni. Lokhu kusabela "kukuphazamiseka" emehlweni hhayi isifo esiyimbangela. I-Uveitis ingenzeka futhi ngenxa yokugula ngokomzimba bese ihlasela iso elilodwa noma womabili.
Izimbangela
- Isuka kumasosha omzimba (idiopathic (ngokwayo) i-immune-mediated uveitis)
Leli fomu elivame kakhulu kuma-85%. Naphezu kokuhlolwa okubanzi kokuxilonga, imbangela ngokuvamile ayitholakali. Kulesi sifo, uhlelo lokuzivikela komzimba (amasosha omzimba) lusabela ngokumelene ne-choroid. Ngesizathu esithile esingaqondakali, umzimba uzihlasela ngokwawo, njengokungathi.
Izidakamizwa ezilwa nokuvuvukala ziboniswa, kokubili endaweni kanye ngomlomo, isikhathi eside, ngezinye izikhathi unomphela.
- Kuyathathelana
Izifo eziningi ezithathelwanayo ezinjeni (izifo zokuhamba ezifana ne-leishmaniasis, i-babesiosis, i-Ehrlichiosis, njll.) kanye namakati (FIV, FeLV, FIP, toxoplasmosis, bartonellosis) zingaholela ku-uveitis. Ukuhlolwa kwegazi okwengeziwe kuyadingeka lapha.
- Isimila
Zombili izimila ezisesweni nezimila emzimbeni (isb. umdlavuza we-lymph node) zingaholela ku-uveitis. Lapha, futhi, ukuhlolwa okwengeziwe (ukuhlolwa kwegazi, i-ultrasound, i-X-rays, njll.) kuboniswa.
- I-Traumatic (shaya, iqhuma)
Ukulimala okubuthuntu noma okubhoboza iso kungalimaza kakhulu izakhiwo ezibucayi esweni. Umphumela we-uveitis ungathinta ingxenye engaphambili yeso (uveitis anterior) noma nengxenye yangemuva (uveitis posterior). Kuye ngezinga lokuhlukumezeka, ukwelashwa kungaphumelela. Ukuhlukumezeka okumaphakathi kuvame ukuba nesibikezelo esihle.
- I-uveitis eyenziwe nge-lens
Lapho i-cataract (i-clouding ye-lens) isithuthuke kakhulu, amaprotheni e-lens avuza esweni. Le phrotheni ikhuthaza amasosha omzimba ukuba azivikele, okuholela ekuvuvukeni (uveitis). Lokhu kugqama kakhulu ezilwaneni ezisencane kanye nalezo lapho ungwengwezi luthuthuka ngokushesha (ushukela). Uma i-lens capsule izinyembezi kanye nenani elikhulu lamaphrotheni lens kukhishwa, iso lingase lingaphenduli ekwelashweni. Konogwaja, ukutheleleka nge-unicellular parasite (Encephalitozoon cuniculi) kuholela ekufipheleni okukhulu kwamalensi ngokugqabuka kwe-lens capsule. Ukuhlolwa kwegazi kunganikeza ulwazi mayelana nesimo sokutheleleka konogwaja.
Ukucindezela ngokweqile emehlweni, okuthiwa yi-glaucoma noma i-glaucoma, kungathuthuka ngemva kwe-uveitis.
Ukwelashwa kufanele kugxile ekubangeleni imbangela ngakolunye uhlangothi futhi ngakolunye uhlangothi, izimpawu kufanele zilwe.
