Yintoni lo wona libutho retina

Retina ukwakweli emva kweso. Kwaye ukuba edlulisela ulwazi yobuchopho ubona abantu. Isekelwe kwi retina ifumana ukukhanya, iiseli zawo ukukhanya-sensitive iyalungiswa nokudlulisela ulwazi engqondweni. Ukuze ekwiretina umsebenzi, kufuneka alandele le ezantsi iliso.

Kwindawo ekunene eziwudibanisayo umzimba vitreous, equka kwimicu zamanzi kunye colloidal. Ugcwalisa ngokupheleleyo isithuba langaphakathi ngaphakathi iliso kwaye ubamba retina eludongeni lwayo.

Yintoni a semehlo lamabutho amehlo? Phantsi yempembelelo yeemeko ezahlukeneyo kusenokuba kusuka eludongeni ongasemva, apho, umbono kuguga okanye inyamalala ngokupheleleyo. Ukongeza, ukuhamba kwegazi semehlo aphazanyiswa kwaye ngenxa yokuba esi siza bangafumani le yesondlo abalufunayo, uyafa. Emva kolu nyango akuthethi ukunika iziphumo.

Isiphumo kukuba ekuphuhliseni amehlo semehlo lamabutho? Oku kaninzi kwenzeka ngenxa yeenguqu kubume vitreous. imicu Colloidal ke zixinaniswe, nto leyo ekhokelela ukuba ukukhutshwa kwamanzi kunye yokunyibilika i vitreous, kwaye, ngenxa yoko, ukuba ukufuduka yayo. Le nkqubo yonakalisa retina ngokusebenzisa ulwelo Amagqabi umonakalo phantsi kwawo eyahlula ukusuka eludongeni. Kungabangela ibutho kunye yokulimala kwamehlo.

iqembu semehlo ixhaphake kakhulu kubantu abadala, ngaba nangona oku akuthethi ukuba akanakuba ngumntu phambi kokuba yobudala ethile. Ukongeza, kukho ezinye iimeko zonyango kuyandisa kakhulu ingozi yokuba esi sifo. Ezi ziquka ukubona (ukubona), isifo seswekile, izifo ezinxulumene-ubudala retina, ukudumba esweni. Abantu abane ezi zifo kufuneka ingqalelo ngokukodwa ukuba umbono wabo. Ngelishwa, abaninzi musa ukucinga ngaloo nto, ingakumbi kuba nje andazi ukuba ukugqiba ukulahleka umbono kungabangela ibutho banal kunye kwiretina. Iimpawu zesi sifo wonke umntu kufuneka wazi:

- flash kunye ibengezela embonweni peripheral;

- umfanekiso kwi embindini ngokutsha ongacacanga kancinci;

- ukuvela kwi "isithunzi", amalengalenga angafihli kwinkalo umbono.

Unyango kwangoko luqala, kokukhona kubonakala ukuba iya kuba nempumelelo. Kungenxa yoko le nto ukufumana ubuncinane enye yezi mpawu, umntu kufuneka kwaoko andibhekisanga zamehlo yakho.

Ngokuxhomekeke ilingene kwecala retina iliso sifikelelwayo, unyango zinokuba nomahluko. Ukuba sithetha nakujoliso olutsha encinane looding, kusenokwenzeka ukwenza inkqubo coagulation laser: cauterize izibhaxu ezincinane kunye laser kwaye ebonakala soldered ubuyele umva. Le nkqubo yalula ngokupheleleyo kwaye lwenziwa qho kwesibhedlele.

Ukuba iqembu semehlo singabalulekanga, kodwa ibekwe ukuze ukusebenzisa laser photocoagulation akunakwenzeka applied ballonirovanie extrascleral: phakathi ithambo kunye sclera waqalisa ibhaloni ezizodwa apho olunyuswe nomoya kumfowunelwa iliso nodonga kwindawo otsloonnoy semehlo, uze kuphela wenziwe moxibustion laser, ebezikuyo ibhaluni isusiwe. Le nkqubo ifuna ukuphumla ebhedini kwaye kwibala ulawulo rhoqo kugqirha.

Kwimeko kokuthanda uqhaqho ngamava semehlo kuyimfuneko. Ukuba inxalenye engaphandle lweliso lakho athungelwe iribhoni eyenziweyo esidala udonga ukuya emqolombeni ukuba uqhagamshelane kunye kwiretina. Olu tyando lwenziwa esibhedlele naphantsi Ukubulawa jikelele.

Kule meko zinzima, vitreous umntu endaweni ngokupheleleyo oyile okanye irhasi leyo eyandisa em- kwaye icinezelwe nxamnye iliso kwi retina iliso.

Kubalulekile ukubona ugqirha ngendlela ngexesha. Ukuba emva kokuba iqembu semehlo phambi kokuba unyango kwakungekho kweeveki ngaphezu kwe-2, ke thina sithetha-80% lokuphumelela, kungenjalo i-risk yokuba kuya kufuneka kwakhona unyango-.
