Ziso uye orbit ultrasound

Ziso uye orbit ultrasound muyedzo wekutarisa panzvimbo yeziso. Iyo zvakare inoyera saizi uye mamiriro eziso.

Muedzo unowanzoitwa muhofisi ye ophthalmologist kana dhipatimendi remaziso muchipatara kana kiriniki.

Ziso rako rakavezwa nemushonga (madonhwe eanesthetic). Iyo ultrasound wand (transducer) inoiswa ichipesana nechemberi pamusoro peziso.

Iyo ultrasound inoshandisa yakakwira-frequency kurira mafungu anofamba kuburikidza neziso. Kufungisisa (maungira) emasaisai ekurira anoumba mufananidzo wechimiro cheziso. Muedzo unotora maminetsi gumi nemashanu.

Kune maviri marudzi ematanho: A-scan uye B-scan.

Zve A-scan:

• Iwe unowanzo gara pachigaro uye woisa chirebvu chako pane chin chin zororo. Iwe unotarisa wakananga kumberi.
• Chidiki chidiki chinoiswa chakanangana kumberi kweziso rako.
• Muedzo unogona zvakare kuitwa newe wakarara kumashure. Nenzira iyi, mukombe wakazara mvura unoiswa kuziso rako kuti uedze.

ZveB-scan:

• Iwe uchagara pasi uye unogona kubvunzwa kuti utarise munzira dzakawanda. Muedzo unowanzoitwa nemeso ako akavharwa.
• Gel rakaiswa paganda remaziso ako. Iyo B-scan probe inoiswa zvinyoro-nyoro ichipesana nemaziso ako kuita bvunzo.

Hapana gadziriro yakasarudzika inodikanwa bvunzo iyi.

Ziso rako rakagomara, saka haufanire kunge uine kusagadzikana. Iwe unogona kubvunzwa kuti utarise munzira dzakasiyana kuti uvandudze iyo ultrasound mufananidzo kana kuti inogona kuona nzvimbo dzakasiyana dzeziso rako.

Iyo gel inoshandiswa neB-scan inogona kumhanya ichidzika padama rako, asi hauzonzwa chero kusagadzikana kana kurwadziwa.

Iwe ungangoda bvunzo iyi kana iwe uine cataract kana mamwe matambudziko eziso.

A-scan ultrasound inoyera ziso kuti rione simba chairo rekuiswa kwema lens pamberi pekuvhiyiwa kwechirwere.

B-scan inoitwa kutarisa mukati mechikamu cheziso kana nzvimbo iri kuseri kweziso iyo isingakwanise kuoneka chaiko. Izvi zvinogona kuitika kana iwe uine cataract kana mamwe mamiriro anoita kuti zviomere chiremba kuti aone kumashure kweziso rako. Iyo bvunzo inogona kubatsira kuongorora retinal detachment, mamota, kana zvimwe zvinetso.

Zve A-scan, zviyero zveziso zviri munzvimbo yakajairwa.

KweB-scan, zvivakwa ziso uye obbit zvinoonekwa zvakajairika.

B-scan inogona kuratidza:

• Kubuda ropa muiyo yakajeka gel (vitreous) inozadza kumashure kweziso (vitreous hemorrhage)
• Gomarara retina (retinoblastoma), pasi peiyo, kana mune mamwe mativi eziso (senge melanoma)
• Nyama dzakakuvara kana kukuvara musony bony socket (orbit) iyo inotenderedza nekuchengetedza ziso
• Mitumbi yekune dzimwe nyika
• Kudhonza kure kweti retina kubva kumashure kweziso (retinal detachment)
• Kuzvimba (kuzvimba)

Kuti udzivise kukwenya iyo cornea, usazora ziso rakabiwa kusvika iyo anesthetic yapera (ingangoita maminetsi gumi nemashanu). Iko hakuna dzimwe njodzi.
