Retinal tsinga kuvharirwa

Retinal arteri kuvharika ndeyekuvharika mune imwe yetsinga diki dzinotakura ropa kuenda ku retina. Iyo retina ndiyo yakatetepa yetishu kumashure kweziso iro rinokwanisa kuona chiedza.

Mitsipa yeRetinal inogona kuvharika kana ropa rikavhara kana mafuta akachengeterwa mutsinga. Aya anovharika angangodaro kana paine kuomarara kwetsinga (atherosclerosis) muziso.

Mavhinga anogona kufamba kubva kune mamwe mativi emuviri uye anovharira tsinga iri mune iyo retina. Izvo zvinowanzoitika masosi emoyo ndiwo moyo uye carotid arteri mumutsipa.

Mazhinji mabhureki anoitika kune vanhu vane mamiriro akadai se:

• Carotid arteri chirwere, umo mairi makuru makuru eropa mumutsipa anova akapfava kana akavharika
• Chirwere cheshuga
• Mwoyo mutinhimira dambudziko (atrial fibrillation)
• Dambudziko revhavha yemoyo
• Kukwirira kwemafuta muropa (hyperlipidemia)
• Kuwedzera kweropa
• Kupinza zvinodhaka zvisina kufanira
• Temporal arteritis (kukuvara kune arteri nekuda kwekudzivirira immune)

Kana bazi retsinga yetsinga rakavharwa, chikamu chetina hachizogashi rakakwana ropa neoksijeni. Kana izvi zvikaitika, unogona kurasikirwa nechikamu chekuona kwako.

Kungoerekana kusaona kana kurasikirwa kwemaonero kunogona kuitika mu:

• Ese eziso rimwe (central retinal artery kuvharirwa kana CRAO)
• Chikamu cheziso rimwe (bazi retinal artery kuvharirwa kana BRAO)

Iyo retinal artery kuvharirwa inogona kugara kwemasekondi mashoma kana maminetsi, kana inogona kunge iri zvachose.

Ropa rakavhara muziso rinogona kunge riri chiratidzo cheyambiro yemachira kumwe kunhu. Ivha muuropi inogona kukonzera sitiroko.

Miedzo yekuongorora iyo retina inogona kusanganisira:

• Kuongorora kwetina mushure mekuwedzera mudzidzi
• Fluorescein angiography
• Kumanikidza kwemukati
• Mudzidzi reflex mhinduro
• Refraction
• Kutora mifananidzo
• Kutsemura rambi kuongorora
• Kwayedzwa yeparutivi chiratidzo (yekuona munda kuongorora)
• Kuona zvakanaka

General bvunzo dzinofanira kusanganisira:

• Ropa kumanikidza
• Ropa bvunzo, kusanganisira cholesterol uye triglyceride mazinga uye erythrocyte sedimentation chiyero
• Kuongorora kwepanyama

Kuyedza kuziva panobva chigadziko kubva kune chimwe chikamu chemuviri:

• Echocardiogram
• Electrocardiogram
• Moyo yekutarisa isina kujairika moyo mutinhimira
• Duplex Doppler ultrasound yeiyo carotid arteri

Iko hakuna kurapwa kwakaratidzirwa kwekurasikirwa kwekuona uko kunosanganisira ziso rese, kunze kwekunge kuchikonzerwa nechimwe chirwere chinogona kurapwa.

Mishonga yakawanda inogona kuyedzwa. Kuti ibatsire, mishonga iyi inofanirwa kupihwa mukati memaawa maviri kusvika mana mushure mekunge zviratidzo zvatanga. Zvisinei, kubatsirwa kweizvi kurapa hakuna kumbobvira kwaratidzwa, uye kashoma kushandiswa.

• Kufemera mukati (inhaling) kabhoni dhayokisaidhi-okisijeni musanganiswa. Mushonga uyu unokonzeresa kuti tsinga dzetina dziwedzere (kureba).
• Massage yeziso.
• Kubviswa kwemvura kubva mukati meziso. Chiremba anoshandisa tsono kuburitsa hushoma hwemvura kubva kumberi kweziso. Izvi zvinokonzeresa kudonha kwakamwe kamwe mukumanikidza kwemaziso, uko kunogona dzimwe nguva kukonzeresa kuti clot iende mune tsinga yebazi diki uko inokonzeresa kukuvara kudiki.
• Mushonga wekuvhara-bata, tishu plasminogen activator (tPA).

Anopa hutano anofanirwa kutarisa chikonzero chekuvharika. Blockages inogona kunge iri zviratidzo zvehupenyu hunotyisidzira dambudziko rekurapa.

Vanhu vane blockages yeiyo retinal artery vangangotadza kuona kwavo kumashure.

Zvinetso zvinogona kusanganisira:

• Glaucoma (CRAO chete)
• Kusarudzika kana kukwana kurasikirwa kwemaonero muziso rakakanganiswa
• Sitiroko (nekuda kwezvinhu zvimwe chete zvinokonzeresa kudzora tsinga kuvharika, kwete nekuda kwekuzvivhara pachayo)

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

Matanho anoshandiswa kudzivirira mamwe maropa eropa (vascular) hosha, senge coronary arteri chirwere, anogona kudzora njodzi yekudzosera tsinga yekuvhara. Izvi zvinosanganisira:

• Kudya kudya kwakaderera-mafuta
• Kudzidzira
• Kurega kusvuta
• Kuderedza uremu kana iwe uri kufuta

Dzimwe nguva, vatete veropa vanogona kushandiswa kudzivirira tsinga kuti isavharwe zvakare. Asipurini kana zvimwe zvinodhaka zvinodzivirira-kugwamba zvinoshandiswa kana dambudziko ririmumatsinga e carotid. Warfarin kana imwe yakanyanya kuwonda kweropa inoshandiswa kana dambudziko riri mumoyo.
