Wakaonekwa munda

Iyo yekuona munda inoreva kune iyo yakazara nzvimbo iyo zvinhu zvinogona kuoneka mune yeparutivi (peripheral) chiratidzo apo iwe uchitarisa maziso ako pane yepakati poindi.

Ichi chinyorwa chinotsanangura bvunzo inoyera yako yekuona munda.

Kukonana kunoonekwa munda bvunzo. Uku kuongorora nekukurumidza uye kwekutanga kwenzvimbo inoonekwa. Anopa hutano anogara akananga pamberi pako. Iwe unovhara rimwe ziso, uye wotarisa wakananga kumberi nerimwe. Iwe uchazobvunzwa kuti utaure kana iwe uchinge waona ruoko rwemuongorori.

Tangent skrini kana bvunzo yegoridhe yeGoldmann. Iwe uchagara anenge matatu tsoka (90 masentimita) kure neyakagadzika, nhema jira jira nechinangwa pakati. Iwe unozobvunzwa kuti utarise kuchinongedzo chepakati uye rega muongorori azive kana iwe uchinge waona chinhu chinofamba muchiono chako chemudivi Chinhu chinowanzova pini kana bead panoperera tsvimbo nhema inotakuriswa nemuongorori. Iyi bvunzo inogadzira mepu yeyako yepakati makumi matatu madhigiri ekuona. Iyi bvunzo inowanzo shandiswa kuona huropi kana tsinga (neurologic) matambudziko.

Goldmann perimetry uye Automated perimetry. Kune chero bvunzo, iwe unogara pamberi pe concave dome uye wotarisa kune chakanangwa pakati. Iwe unodzvanya bhatani paunoona kupenya kudiki kwechiedza mune yako yekumeso kuona. NaGoldman kuyedza, kupenya kunodzorwa uye kurongedzwa nemuongorori. Iine otomatiki kuyedza, komputa inodzora kupenya uye mepu. Mhinduro dzako dzinobatsira kuona kana uine chakaremara mundima yako yekuona. Ose maedzo bvunzo anowanzo shandiswa kuteedzera mamiriro anogona kukuvadza nekufamba kwenguva.

Wako mupi achakurukura newe mhando yekuona munda kuyedza kuti kuitwe.

Hapana gadziriro yakakosha inodikanwa.

Iko hakuna kusagadzikana nekuona munda kuyedza.

Uku kuongorora kwemaziso kucharatidza kana iwe uine kurasikirwa kwemaonero chero kupi mune yako yekuona munda. Iyo pateni yekuona kurasikirwa kuchabatsira mupi wako kuona icho chikonzero.

Iyo yekumusoro maonero ndeye zvakajairika.

Mhedzisiro isingaite inogona kunge iri nekuda kwezvirwere kana epakati nervous system (CNS) kusagadzikana, senge mamota anokanganisa kana kutsikirira (kumanikidza) zvikamu zvehuropi zvinotarisana nekuona.

Zvimwe zvirwere zvinogona kukanganisa kuona kweziso zvinosanganisira:

• Chirwere cheshuga
• Glaucoma (yakawedzera kumanikidza kwemaziso)
• Kuwedzera kweropa
• Zera-rakabatana macular degeneration (ziso kusagadzikana iro rinoparadza zvishoma nezvishoma rakapinza, repakati chiratidzo)
• Multiple sclerosis (kusagadzikana kunokanganisa iyo CNS)
• Optic glioma (bundu retsinga yemaziso)
• Utachiona hwakanyanya (hyperthyroidism)
• Pituitary gland kusagadzikana
• Retinal detachment (kupatsanurwa kwetina kumashure kweziso kubva pamatanho aro anotsigira)
• Kurohwa
• Temporal arteritis (kuzvimba uye kukuvadza kune tsinga dzinopa ropa kumusoro uye zvimwe zvikamu zvemusoro)

Muedzo hauna njodzi.
