I-Nystagmus ukunyakaza okungahambisani nesigqi se-oscillatory yamehlo womabili noma okungavamile kakhulu kweso elilodwa.

Kunezinhlobo ezimbili ze-nystagmus:

• i-pendular nystagmus, eyenziwe ngama-sinusoidal oscillations wejubane elifanayo
• nentwasahlobo yenystagmus enesigaba esisheshayo esishintshana nesigaba esisheshayo sokulungisa

Ezimweni eziningi kakhulu, i-nystagmus ivundlile (ukunyakaza kusuka kwesokudla kuye kwesobunxele nakwesobunxele kuye kwesokudla).

INystagmus ingaba uphawu olujwayelekile noma ingaxhunyaniswa ne-pathology eyisisekelo.

I-nystagmus yomzimba

I-Nystagmus ingaba uphawu olujwayelekile ngokuphelele. Kuyabonakala kubantu ababuka izithombe ezidlula phambi kwamehlo abo (isihambi esihleli esitimeleni futhi sizama ukulandela izithombe zezwe elidlula phambi kwakhe). Lokhu kubizwa ngokuthi i-optokinetic nystagmus. Kubonakala ngochungechunge lwamajezi ahamba kancane esweni elandela into ehambayo kanye nejezi esheshayo ebonakala ikhumbula inhlamvu yeso.

I-nystagmus yezifo

Kuvela ekukhubazekeni kwesilinganiso phakathi kwezinhlaka ezahlukahlukene ezibhekele ukuzinza kweso. Inkinga ngakho-ke ingaqamba amanga:

- ezingeni leso

- ezingeni lendlebe yangaphakathi

- ezingeni lezindlela zokuqhuba phakathi kweso nobuchopho.

- ezingeni lobuchopho.
