Retinitis pigmentosa

Retinitis pigmentosa chirwere cheziso umo mune kukuvara kune iyo retina. Iyo retina ndiyo yakatetepa yetishu kumashure kweziso remukati. Rukoko urwu runoshandura mifananidzo yakajeka kuva masaini etsinga uye ndokutumira kuuropi.

Retinitis pigmentosa inogona kumhanya mumhuri. Iyo kusagadzikana kunogona kukonzerwa neakawanda magenge kuremara.

Iwo maseru anodzora maonero ehusiku (tsvimbo) anowanzo kuve anokanganiswa. Zvisinei, pane dzimwe nguva, masero ekoni eretina akakuvara zvakanyanya. Chiratidzo chikuru chechirwere ndiko kuvapo kwemativi erima muiyo retina.

Iyo yakanyanya njodzi njodzi ndeye nhoroondo yemhuri ye retinitis pigmentosa. Icho chiitiko chisingawanzo kubata chinenge 1 muvanhu zviuru zvina muUnited States.

Zviratidzo zvinowanzotanga kuoneka muhudiki. Zvisinei, zvinetso zvakakomba zvekuona hazviwanzo kukura munhu asati akura.

• Kupera kwekuona husiku kana mune yakaderera mwenje. Zviratidzo zvekutanga zvinogona kusanganisira kuve nenguva yakaoma yekufamba murima.
• Kurasikirwa kwerutivi (peripheral) kuona, zvichikonzera "tunnel kuona."
• Kurasikirwa kwepakati pekuona (mune yepamusoro kesi). Izvi zvinokanganisa kugona kuverenga.

Kuyedza kuongorora iyo retina:

• Ruvara chiratidzo
• Ongororo yeiyo retina ne ophthalmoscopy mushure mekunge vadzidzi vaderedzwa
• Fluorescein angiography
• Kumanikidza kwemukati
• Kuyerwa kwechiitiko chemagetsi muitina (electroretinogram)
• Mudzidzi reflex mhinduro
• Refraction bvunzo
• Kutora mifananidzo
• Rutivi rwekuona bvunzo (rinoonekwa munda bvunzo)
• Kutsemura rambi kuongorora
• Kuona zvakanaka

Iko hakuna kurapwa kunoshanda kweichi chiitiko. Kupfeka magirazi ezuva kudzivirira retina kubva kune ultraviolet mwenje kunogona kubatsira kuchengetedza kuona.

Zvimwe zvidzidzo zvinoratidza kuti kurapwa nema antioxidants (senge mwero wakakura wevitamini A palmitate) kunogona kudzora chirwere ichi. Zvisinei, kutora mizinga yakawanda yevhitamini A kunogona kukonzera zvinetso zvakakomba zvechiropa. Kubatsirwa kwekurapa kunofanira kuyerwa kutarisana nenjodzi kune chiropa.

Makiriniki miedzo iri kuenderera mberi kuongorora marapirwo matsva eretinitis pigmentosa, kusanganisira kushandiswa kweDHA, inova omega-3 fatty acid.

Mimwe mishonga yekurapa, senge microchip implant mu retina iyo inoita senge microscopic vhidhiyo kamera, iri mumatanho ekutanga ebudiriro. Aya marapirwo anogona kuve anobatsira ekurapa hupofu hwakabatana neDP uye nezvimwe zvakakomba maziso maziso.

Nyanzvi yekuona inogona kukubatsira kujairana nekurasikirwa kwemaonero. Gara uchishanyira nyanzvi yezvekutarisira maziso, uyo anokwanisa kuona kuzvimba kwemaziso kana kuzvimba kweziso. Matambudziko ese aya anogona kurapwa.

Dambudziko racho richaramba richifambira mberi zvishoma nezvishoma. Kupofumadza kwakazara hakuwanzoitika.

Peripheral uye yepakati kurasikirwa kwemaonero kuchaitika nekufamba kwenguva.

Vanhu vane retinitis pigmentosa vanowanzo kuve nemaziso vachiri vadiki. Vanogona zvakare kukudziridza kuzvimba kweti retina (macular edema). Makaroketi anogona kubviswa kana iwo achizopa pakurasikirwa kwemaonero.

Bata wako mupi wezvehutano kana iwe uine matambudziko nehusiku kuona kana iwe uchikura zvimwe zviratidzo zvechirwere ichi.

Kurairidzwa uye kuongorora kunogona kubatsira kuona kana vana vako vari panjodzi yechirwere ichi.
