Lamabutho ngwengwzi: izimpawu kanye izimbangela zesifo

Vision - lokhu kuyisipho enkulu esisinikezwa nemvelo. Njengoba wazi, iningi ulwazi esiluthola yokukhulumisana ezibukwayo nezwe. Futhi uma ukuxhumana kulinganiselwe khona noma kungenziwa, ngezinye izikhathi, yayizovela ku imikhawulo ubuncane, kukhona nhlekelele yangempela.

Izifo umbono. I nzima kakhulu futhi ezinzima phakathi kwayo i- lamabutho retina.

Retin-A - lena ingxenye eyinhloko iso ukuthi unesibopho ukuguqulela ukukhanya imisebe nezinzwa amaza ukuthi uthumela ebuchosheni. Kusukela esimweni saso kuncike ngqo umbono yomuntu. Ngakho-ke, ukuthola okungazelele ka lamabutho ngwengwzi noma ukwelashwa ayilungile kungaholela ukulahlekelwa esinqunyiwe umbono noma, ngokuvamile, ubumpumputhe.

Izimpawu lamabutho ngwengwzi eshiwo ku ikhefu-retina kanye Ukungena uketshezi emzimbeni Vitreous we inhlamvu yeso ngaphansi kwe-retina, okuyinto enomthelela ngokwahlukana yayo kusukela choroid.

Ukudabuka retina ngokuvamile kwakheka at thinning yayo noma sokuwohloka, kanye ukulimala ahlukahlukene iso. Waba yini umphumela wesibindi izifo eziningi iso ingavuthi extractor Vitreous noma okuthiwa traction, ezingasetshenziswa futhi lula ukudabuka. Kulokhu, lo Vitreous iba liguqubele Imicu yotshani yayo uxhumeke kwi-retina, i-sebebekwe uphawu. Lapho ushayela, baba ukudonsa amehlo akhe. Lona isizathu ikhefu.

Isimila noma iyiphi enye imfundo phakathi retina kanye choroid ingabagulisa lamabutho ngwengwzi. Izimpawu zibonisa ukuthi kungase kwenzeke kwegazi lapho abampofu, ukucindezeleka, sindisa ngokomzimba, kanye nezifo ezihlukahlukene.

Ukuvela kwesihenqo umuzwa phambi kwamehlo kuyinkomba egqame bha ukuthi kukhona lamabutho ngwengwzi. Izimpawu ngasocansini lesi sifo, kubalulekile ukukhumbula, bese benika uthisha udokotela, futhi ungazami ukuqeda indwangu usebenzisa amaconsi futhi izona.

"Flash", 'izinhlansi "futhi" Umbani "- futhi izimpawu buthule lesi sifo. Ziyakwazi ngowokuqala ukunikeza kuwuphawu lokuthi kukhona okwenzekayo ngamehlo.

Uma lamabutho isivele athumba ngumgogodla ezikhungweni zomsebenzi retina, ukuthi kukhona ukuhlanekezela noma ukulahleka izinto, izincwadi, wonke izigaba zomuntu ngamunye isithombe emhlabeni.

Ngezinye izikhathi umuntu uthi, ukuthi umbono kancane ngcono. Kodwa lokhu ukuzwa sobala. Uma isiguli endaweni evundlile, i-retina uphindela endaweni yalo, kodwa uma umuntu kumele bame kuphi, futhi asuka choroid futhi umbono kulahleka futhi.

High blood pressure, ukuvela imizwa ka-strabismus, ukufiphala yesithombe ebonakalayo uthi kwenzekani lamabutho ngwengwzi. Izimpawu kubonisa ingozi ukuvuvukala okungamahlalakhona, lolu ngwengwezi futhi ngokungaboni nhlobo.

Uma ngezikhathi hlola acuity ezibukwayo, le lamabutho ngwengwzi, ogama izimpawu uxilongwe, ke kungavinjelwa. Imiphumela yaloku kuhlola okungenhla kuhlanganisa nesilinganiso yangaphakathi iso ingcindezi, ukutadisha umbono lateral, luhlolo we fundus. Ukutadisha iso esebenzisa ultrasound izonikeza isithombe esicacile isimo Vitreous futhi retina.

Yelaphani amehlo ngwengwzi lamabutho, izimpawu zazo kakade eshiwo ngokucacile, ngosizo amaphilisi noma lehla abakwazi. Amandla Ukugcina nokulonda amehlo can kuphela ukuhlinzwa. Phakathi ukuhlinzwa, udokotela ohlinzayo owenza uhlobo 'osekela ngcono "yokumboza futhi choroid.

Izindlela ezivame kakhulu ezisetshenziswayo ekuhlinzeni ngaphandle iso futhi esetshenziswa ekwelashweni ebuthweni ngwengwzi, abagcwalisa futhi vitrectomy.

Uma ugcwalisa ukuba "gluing" laser isetshenziswa futhi wasuswa usebenzisa igazi vitrectomy kusukela Vitreous, nezibazi nezinye izinto.
