I-Uveitis kukuvuvukala kwe-iris kunye/okanye i-choroid/retina kwiliso. Oku kusabela "kwi-disorder" kwiso kwaye kungekhona isifo se-causative. I-Uveitis inokuthi yenzeke ngenxa yesigulo somzimba kwaye emva koko ichaphazele ilihlo elinye okanye omabini.
Izizathu
- Ivela kwi-immune system (idiopathic (ngokwayo) i-immune-mediated uveitis)
Le yeyona ndlela ixhaphakileyo kuma-85%. Ngaphandle kovavanyo olubanzi lokuxilonga, unobangela kaninzi awunakuchazwa. Kwesi sifo, inkqubo yokhuselo lomzimba (i-immune) isabela ngokuchasene ne-choroid. Ngesizathu esingaqondakaliyo, umzimba uzihlasela ngokwawo, ngokungathi kunjalo.
Izidakamizwa ezichasayo ziboniswa, zombini kunye nomlomo, kwixesha elide, ngamanye amaxesha ngokusisigxina.
- Usulelo
Izifo ezininzi ezosulelayo ezinjeni (izifo zokuhamba ezifana ne-leishmaniasis, i-babesiosis, i-Ehrlichiosis, njl.) kunye neekati (FIV, FeLV, FIP, toxoplasmosis, bartonellosis) inokukhokelela ekubeni uveitis. Uvavanyo olongezelelweyo lwegazi luyimfuneko apha.
- Ithumba
Omabini amathumba kwiliso kunye namathumba emzimbeni (umzekelo umhlaza we-lymph node) angakhokelela ekubeni uveitis. Apha, kwakhona, iimviwo ezongezelelweyo (uvavanyo lwegazi, i-ultrasound, i-X-rays, njl.) ziboniswa.
- Umothuko (ukubetha, ukungqubeka)
Ukwenzakala okungacacanga okanye okugqobhozayo kwiliso kunokonakalisa kakhulu izakhiwo ezibuthathaka kwiso. Isiphumo se-uveitis sinokuchaphazela icandelo elingaphambili leliso (uveitis anterior) okanye icandelo elingasemva (uveitis posterior). Ngokuxhomekeke kwiqondo lokwenzakala, unyango lunokuphumelela. Umonzakalo ophakathi udla ngokuba nengqikelelo efanelekileyo.
- I-Lens-induced uveitis
Xa i-cataract (ilifu le-lens) ihambele phambili kakhulu, iprotein yelensi ivuza iliso. Le proteni ivuselela amajoni omzimba ukuba azikhusele, nto leyo ekhokelela ekudumbeni ( uveitis ). Oku kubonakala ngakumbi kwizilwanyana ezincinci kunye nezo apho i-cataract iqhubela phambili ngokukhawuleza (isifo sikashukela). Ukuba i-lens capsule iinyembezi kunye nezixa ezikhulu zeprotheyini ye-lens zikhutshwa, iliso alinakuphendula kunyango. Kwimivundla, ukosuleleka nge-unicellular parasite (Encephalitozoon cuniculi) kukhokelela kumafu amabi kwiilensi ngokugqabhuka kwe-lens capsule. Uvavanyo lwegazi lunokubonelela ngolwazi malunga nesimo sosulelo lomvundla.
Uxinzelelo olugqithisileyo kwiso, okubizwa ngokuba yi-glaucoma okanye i-glaucoma, inokukhula emva kwe-uveitis.
Unyango kufuneka lugxininise kwisizathu esibangelayo kwelinye icala kwaye kwelinye icala, iimpawu kufuneka zilwe.
