Into efihlakeleyo yeliso yi-retina. Inesakhiwo esiyinkimbinkimbi esivumela ukuba sibone amaza okukhanya. Le ngxenye yombutho wombono odibanisa inkqubo ye-optical kunye neengxenye ezihambelana nengqondo. I-Detachment ye-retina ithathwa njengengxaki enkulu kwaye iimpawu zayo zenza ukuba unyango lunokwenzeka. Kwiimpawu zokuqala kubalulekile ukuphendukela kwiingcali.
Iindidi zokwehliswa
Ukugula kubangelwa ngenxa yokuhlukana kwimbumba yentsimbi kwi-vascular. Ukuba kukho imeko efanayo, kufuneka uhambe kwiziko lonyango, ngaphandle koko kunokukhokelela ekuboni.
Kukho iintlobo ezininzi ze-retinal detachment, ngasinye sichazwe yimbangela yesifo seso:
- Regmatogenic. I-detachment yaseprayimari, ngenxa yoko ngenxa yokuphulukana kwe-retina ingena kumanzi kwi-lens. Isizathu esibalulekileyo sincinci. Kukho iintlobo ezininzi: i-trellised, i-racemose nabanye abaninzi. Inokuvela ngenxa yokuhamba ngokukhawuleza, ubunzima bomzimba okanye kwedwa.
- Utyando. Eli qela lenzeke ngenxa yentsholongwane yokubuyisela ngenxa ye-lens, ekubeni ukufakwa okutsha kubonakala kuyo. Ziyakwenzeka ngezifo ezahlukahlukeneyo, umzekelo, isifo se-diabetes retinopathy.
- Ezibuhlungu. Isifo sinokubangelwa ngumonakalo owenziwe ngeso liso. Ngelo xesha, eli qela libonakala, zombini kunye kunye neminyaka emininzi.
- Sekondari. Kubonakaliswa ngenxa yentsholongwane ehambelana namaziko ombono: izifo ezahlukeneyo ezivuthayo, ukubola , i-thrombosis kunye nezinto ezinje.
- Exudative. I-retina ihlala ihleli kakuhle, ngelixa umbane uqokelela phantsi kwayo.
Iimpawu kunye neempawu ze-retinal detachment
Esinye sezibonakaliso eziphambili zesithenjwa sithathwa njenge-photopsy, njengesiphumo sokuthi umntu ubonakala enjengemibane nemililo kwintsi yombono. Oku kubangelwa kukuba i-retina ivelisa iimvakalelo kungekhona kuphela xa ukukhanya kuhlasela, kodwa nangaphantsi kwefuthe lomzimba.
Ukongezelela, "iintambo" ezijikelezayo, "amanqaku" kunye neminye imifanekiso emincinci ingabonakala phambi kwamehlo akho. Lo mcimbi awuthathwa njengomntu ngamnye kwaye awunxulumene ngqo nesi sifo. Kuqhelekileyo kwaye ayidingi unyango oluphuthumayo. Ngokuqhelekileyo, le mpawu ibonisa ukutshatyalaliswa kwe-lens.
Ngaphantsi kaninzi abantu banokugcina izinto ezibizwa ngokuba yi-Weiss izindandatho - izibonda eziphazamisekileyo. Oku kubonisa iqela le-membrane yangasemva kwendawo yesinamathiselo. Le meko ayifuni imfuneko yokubhedlele ngokukhawuleza. Nangona kunjalo, iimpawu ezifanayo zingaba iimpawu zokuqala zesithenjwa sokubuyisela kubangelwa ukubola kwegazi kwi-vitreous element.
Ukuxilongwa kwe-peeling
Ukuze isigulane sibe nethemba ngokupheleleyo ekuxilongeni "kwinqaku lokubuyisela," kufuneka ahlolisiswe ngokusemthethweni ngamalungu ombono. Iiklinikhi zanamhlanje zikuvumela ukuba uhlolisise eso sifo ngokukhawuleza emva kokuvavanya isigulane ngezixhobo zekhompyutha. Yile nto eyenza sikwazi ukudala umfanekiso opheleleyo wesimo somntu.
Ukufundwa kwesigulane, obeneempawu zokuqala zokugcina i-retinal, iqulethwe ngu:
- uviwo lwezinto ezibonakalayo - oku kuya kunceda ekufumaneni imeko yangempela yale nxalenye yelihlo kunye nomzenzeko;
- inkqubo ye-electrophysiological eyenza ukukwazi ukubuyisela ukuphela kwezibilini ze-optic nererve ngokwayo;
- ukuskena kwe-ultrasound, evumela ukuba ufumane isakhiwo sangaphakathi sehlo;
- uviwo lwe- fundus .
Ukunyuka kokukhawuleza kwonyango kuya kwandisa kakhulu amathuba okubuya kwakhona.
