Isifinyezo

Imizwa ye-optic iyinqwaba yemicu yezinzwa engaphezu kwesigidi esihamba nemiyalezo ebonakalayo. Unayo eyodwa exhuma ngemuva kweso ngalinye (i-retina yakho) ebuchosheni bakho. Ukulimala kwethambo le-optic kungadala ukulahleka kombono. Uhlobo lokulahleka kombono nokuthi kubi kangakanani kuncike lapho kwenzeka khona umonakalo. Kungathinta iso elilodwa noma womabili.

Kunezinhlobo eziningi zokuphazamiseka kwemizwa ye-optic, kufaka phakathi:

• IGlaucoma iyiqembu lezifo okuyizimbangela ezihamba phambili zobumpumputhe e-United States. I-glaucoma ivame ukwenzeka lapho ingcindezi ketshezi ngaphakathi kwamehlo inyuka kancane futhi ilimaze imizwa ye-optic.
• I-optic neuritis ukuvuvukala kwemizwa ye-optic. Izimbangela zifaka ukutheleleka kanye nezifo ezihlobene nomzimba ezifana ne-multiple sclerosis. Kwesinye isikhathi imbangela ayaziwa.
• I-optic nerve atrophy ingumonakalo we-optic nerve. Izimbangela zifaka ukugeleza kwegazi okungahambi kahle esweni, izifo, ukuhlukumezeka, noma ukuvezwa kwezinto ezinobuthi.
• I-optic nerve head drusen yizikhwama zamaprotheni kanye nosawoti we-calcium ezakha emthanjeni we-optic ngokuhamba kwesikhathi

Xhumana nomhlinzeki wakho wezokunakekelwa kwempilo uma unezinkinga zombono. Ukuhlolwa kokuphazamiseka kwemizwa ye-optic kungafaka izivivinyo zamehlo, i-ophthalmoscopy (ukuhlolwa kwangemuva kweso lakho), kanye nokuhlolwa kwe-imaging. Ukwelashwa kuya ngesifo onaso. Ngezinkinga ezithile ze-optic nerve, ungabuyisa umbono wakho. Kwabanye, alukho umuthi, noma ukwelashwa kungavimbela ukulahleka kombono okuqhubekayo.
