Kutsiva mutsinga

Kuvhara tsinga kweRetinal kuvharika kwetsinga diki dzinotakura ropa kubva patiri. Iyo retina ndiyo yakatetepa yetishu kumashure kweziso remukati inoshandura mifananidzo yakajeka kuva masaini etsinga uye kuatumira kuuropi.

Kuvhara mutsipa kweRetinal kunowanzo kukonzerwa nekuomarara kwetsinga (atherosclerosis) uye kuumbwa kweropa.

Kuvharika kwetsinga diki (tsinga dzebazi kana BRVO) mu retina kazhinji kunoitika munzvimbo dzinotapira tsinga dzakaomeswa kana kuomeswa ne atherosclerosis kuyambuka nekuisa kumanikidza kwetsinga yemaziso.

Njodzi zvinhu zvetisheni vein kuvharirwa zvinosanganisira:

• Atherosclerosis
• Chirwere cheshuga
• Kuwedzera kweropa (hypertension)
• Mimwe mamiriro eziso, senge glaucoma, macular edema, kana vitreous hemorrhage

Ngozi yezvinetso izvi inowedzera nezera, nekudaro retina vein kuvharirwa kazhinji kunokanganisa vanhu vakuru.

Kuvharika kwetsinga dzemaziso kunogona kukonzera mamwe matambudziko eziso, kusanganisira:

• Glaucoma (yakanyanya kumanikidza muziso), inokonzerwa nemidziyo mitsva, isina kujairika yeropa inokura muchikamu chepamberi cheziso.
• Macular edema, inokonzerwa nekudonha kwemvura mune iyo retina

Zviratidzo zvinosanganisira kupenya kamwe kamwe kana kurasikirwa kwemaonero mune zvese kana chikamu cheziso rimwe.

Kuyedzwa kwekuyera kwevein kuvharirwa kunosanganisira:

• Kuongorora kwetina mushure mekuwedzeredza mwana wechikoro
• Fluorescein angiography
• Kumanikidza kwemukati
• Mudzidzi reflex mhinduro
• Refraction ziso bvunzo
• Kutora mifananidzo
• Kutsemura rambi kuongorora
• Kwayedzwa yeparutivi chiratidzo (yekuona munda kuongorora)
• Kuona acuity bvunzo kuti uone mavara madiki diki iwe aunogona kuverenga pane chati

Mimwe bvunzo inogona kusanganisira:

• Kuongororwa kweropa kune chirwere cheshuga, cholesterol yakawanda, uye mwero we triglyceride
• Ropa bvunzo kutarisa dambudziko rekugwamba kana reropa (hyperviscosity) dambudziko (muvanhu vari pasi pemakore makumi mana emakore)

Mutapi wezvehutano anoongorora zvakanyanya kuvharika kwemwedzi yakati wandei. Zvinogona kutora 3 kana anopfuura mwedzi yezvinhu zvinokuvadza senge glaucoma kukura mushure mekuvharirwa.

Vanhu vazhinji vanozoonazve kuona, kunyangwe vasina kurapwa. Zvisinei, chiratidzo hachiwanzo kudzokera kune zvakajairika. Iko hakuna nzira yekudzosera kana kuvhura iyo kuvharira.

Ungangoda kurapwa kudzivirira kumwe kuvharika kubva mukuumbwa mune rimwe kana rimwe ziso.

• Zvakakosha kugadzirisa chirwere cheshuga, BP, uye cholesterol yakawanda.
• Vamwe vanhu vangangoda kutora asipurini kana vamwe vanoonda ropa.

Kurapa kwezvinetso zve retinal vein kuvharirwa kunogona kusanganisira:

• Focal laser kurapwa, kana macular edema iripo.
• Majekiseni eanti-vascular endothelial kukura chinhu (anti-VEGF) zvinodhaka muziso. Iyi mishonga inogona kudzivirira kukura kwemidzi mitsva yeropa iyo inogona kukonzera glaucoma. Iyi kurapwa ichiri kuongororwa.
• Laser kurapwa kudzivirira kukura kwemitsva, isina kujairika mitsipa yeropa inotungamira kune glaucoma.

Mhedzisiro yacho inosiyana. Vanhu vane retina vein kuvharirwa kazhinji vanowanazve chiono chinobatsira.

Izvo zvakakosha kunyatsogadzirisa mamiriro akadai macular edema uye glaucoma. Nekudaro, kuve neimwe yeaya matambudziko kunowanzo kutungamira kune yakashata mhedzisiro.

Zvinetso zvinogona kusanganisira:

• Glaucoma
• Kusarura kana kukwana kurasikirwa kwemaonero muziso rakakanganiswa

Fonera mupiki wako kana iwe ukangoerekana waita blurring kana kuona kurasikirwa.

Retinal vein kuvharirwa chiratidzo cheyese yeropa mudziyo (vascular) chirwere. Matanho anoshandiswa kudzivirira zvimwe zvirwere zvemutsipa weropa zvinogona kudzora njodzi yekuvharwa kwetsinga.

Aya matanho anosanganisira:

• Kudya kudya kwakaderera-mafuta
• Kuwana kurovedza muviri nguva dzose
• Kuchengeta huremu hwakakwana
• Kwete kusvuta

Asipurini kana mamwe madhiri eropa anogona kubatsira kudzivirira kuvharika mune rimwe ziso.

Kudzora chirwere cheshuga kunogona kubatsira kudzivirira retina vein kuvhara.
