Uyini lamabutho retina

I-retina isendaweni ngemuva iso. Futhi ukuthi adlulisele ulwazi zobuchopho ubona abantu. Through the lens ungene retina uthola ukukhanya, amaseli ayo ukukhanya-sensitive benzelwe futhi udlulise ulwazi ebuchosheni. Ukuze i-retina umsebenzi, kumele zithobele phansi iso.

Esikhathini isikhundla kwesokudla ngoba kunesithembiso umzimba Vitreous, esakhiwa amanzi colloidal zesivikelo sesifuba. It igcwalisa ngokuphelele isikhala elingaphakathi ehlweni futhi uphethe i-retina nodonga lwawo.

Uyini ngwengwzi lamabutho amehlo? Ngaphansi kwethonya izici ezahlukene kungase kufike kususwa udonga lwangemuva, lapho, umbono liwohloka noma ngokuphelele iphele. Ngaphezu kwalokho, ngwengwzi ukugeleza kwegazi kuyaphazamiseka futhi ngenxa yokuthi le sayithi awutholi umsoco badinga, efa. Ngemva kwale kwelashwa akukuniki imiphumela.

Umphumela uba ukuthi ukuthuthukisa amehlo ngwengwzi lamabutho? avame Lokhu kwenzeka ngenxa yezinguquko isakhiwo Vitreous. Imicu yotshani colloidal ziya onomfutho, okuholela ukukhululwa yamanzi kanye liquefaction we Vitreous, futhi ngenxa yalokho, ukuze ukufuduka yayo. Le nqubo umonakalo retina futhi ngokusebenzisa ketshezi engena umonakalo ngaphansi kwaso futhi ehlukanisa ke kusukela odongeni. Kungabangela lamabutho kanye yokulimala kwamehlo.

lamabutho ngwengwzi kuvamile kakhulu abantu abadala, nakuba lokhu akusho ukuthi akunakuba umuntu ngaphambi kweminyaka ethize. Ngaphezu kwalokho, kukhona ezinye izimo zezokwelapha ukuthi ukwandisa kakhulu ingozi yokuba lesi sifo. Lezi zihlanganisa myopia (ukubona eduze), isifo sikashukela, izifo ezihlobene nokukhula kwe-retina, ukuvuvukala iso. Abantu nalezi izifo kumelwe anakekele ikakhulukazi ukuba umbono wabo. Ngeshwa, abaningi abacabangi ngakho, ikakhulukazi ngoba nje asazi ukuthi ukuqeda ukulahlekelwa umbono kungaholela ihlukane banal futhi retina. Izimpawu zalesi bonke isifo Kufanele wazi:

- flash nenkazimulo ku umbono neuropathy;

- isithombe maphakathi isibuyekezo kancane ezingacacile;

- ukubonakala 'isithunzi', amakhethini obala emkhakheni umbono.

Ukwelapha ngaphambili iqala, aba maningi amathuba okuba ukuthi siyophumelela. Yingakho ekutholeni okungenani eyodwa yalezi zimpawu, umuntu kufanele ngokushesha uthintane ophthalmologist yakho.

Kuye ngalokho degree ebuthweni retina esweni ufinyelelwe, ukuphathwa zingase zihluke. Uma sikhuluma foci elincane lamabutho, kungenzeka ukwenza laser inqubo coagulation: cauterize izilonda ezincane laser futhi ebonakala soldered enye ngemuva kwenye. Le nqubo kuba kobuhlungu ngokuphelele futhi iqhutshwa esigulini esingalalisiwe esibhedlela.

Uma lamabutho ngwengwzi ongabalulekile lowo, kodwa itholakala ukuze isicelo laser photocoagulation kungenzeki osetshenziswayo ballonirovanie extrascleral: phakathi ithambo kanye sclera owethulwa ibhaluni ekhethekile okuyinto ulele ne air kuya kuchumana ngemehlo odongeni endaweni otsloonnoy ngwengwzi, bese kuphela eyenziwa moxibustion laser, ngalokho ibhaluni iyasuswa. Le nqubo kudinga embhedeni ukuphumula futhi owawuseHholo ukulawula njalo udokotela.

Endabeni okwandile ngwengwzi ukuhlinzwa lamabutho kuyadingeka. Ukuze ingxenye elingaphandle yeso Ithungelwe iribhoni zokwenziwa elibangela odongeni ukuze wehlulwe uxhumane ne-retina. Ukusebenza wenziwa esibhedlela ngaphansi izinzwa jikelele.

Ngo nasezimweni ezinzima kakhulu, Vitreous umuntu esikhundleni ngokuphelele uwoyela noma igesi lapho inwebeka e ngalo ingaphakathi futhi yayicindezele iso ukuze retina esweni.

Kubalulekile ukubona udokotela ngendlela esifike ngesikhathi. Uma emva lamabutho ngwengwzi ngaphambi ukwelashwa kwakungekho amasonto angaphezu 2, bese sikhuluma 80% impumelelo, kungenjalo kunengozi ukuthi uzodinga kabusha ukwelashwa.
