Yintoni ii-float, iimpawu kunye nendlela yokunyanga

Umxholo

• Iimpawu eziphambili
• Unyango lwenziwa njani

Amanqwanqwa ngamabala amnyama, afana ne-filaments, izangqa okanye iiwebhu, ezibonakala ebaleni lokujonga, ngakumbi xa ujonga umfanekiso ocacileyo, njengephepha elimhlophe okanye isibhakabhaka esibhakabhaka.

Ngokubanzi, ii-float emehlweni zivela ngokwaluphala, ngenxa yeziphene kwi-vitreous, eyinxalenye yejelatinous yamehlo, nangona kunjalo, zinokwenzeka nakwizigulana ezisencinci ngenxa yamanqaku amancinci e-retina, nangona ingaphazamisi i-retina. , yenza amaqhuma anokudada kwi-vitreous fluid, kwaye enze izithunzi eziqikelelwe kwi-retina.

Iiflaat ziyanyangeka ngotyando endaweni ye-vitreous yamehlo, nangona kunjalo, utyando luyacetyiswa kuphela kwizigulana ezinenani elikhulu lamachaphaza, ukuthintela ukwenziwa kwemisebenzi yemihla ngemihla, njengoko uninzi lwamaxesha olu tshintsho lungaqhelekanga ukukhathazeka kwaye akuchaphazeli umbono obonakalayo.

Iimpawu eziphambili

Iimpawu ze-float ikakhulu kukubonakala kwamabala amnyama kwicandelo lombono:

• Ziyafana neempukane, amachaphaza, imisonto okanye imigca ecacileyo exhonywe emoyeni;
• Zihamba xa amehlo eshukunyiswa okanye xa zizama ukuwajonga;
• Kulula ukuzijonga xa ujonga kumphezulu omhlophe, njengodonga.

Kwiimeko apho ezinye iimpawu zivela khona, ezinjengokukhanya, ukwehla kombono okanye ukubamnyama emacaleni ombono, kubalulekile ukuba ubonane nogqirha wamehlo ngokukhawuleza ukuze ufumanise ingxaki kwaye uqalise ngonyango olufanelekileyo, njengoko zinokubonisa iingxaki ezinkulu , ezinje ngethimba le-retina. Qonda ukuba yeyiphi i-retinal detachment kwaye uyiphatha njani.

Unyango lwenziwa njani

Unyango lwee-float emehlweni kufuneka luboniswe kwaye lukhokelwe ngugqirha wamehlo, kuba, kwiimeko ezininzi, akukho hlobo lonyango luyimfuneko, kwaye isigulana kufuneka siziqhelanise nokubona ngale ndlela.

Nangona kunjalo, xa isiguli sele sisazi ukuba sinezinto ezidadayo, kufuneka siphinde sibonane nogqirha nanini na xa amabala esonyuka ngobukhulu okanye ngenani, esenza ukuba kube nzima ukubona. Jonga iimpawu zeengxaki zombono ezinokuthi zikulumkise kwimfuno yokubona ugqirha wamehlo.

Nangona kunjalo, kwezona meko zinzima, apho amabala embonweni makhulu kakhulu okanye avele ngamanani amakhulu, ugqirha unokucebisa ukuba kwenziwe utyando ukunyibilikisa amabala okanye ukubuyisela i-vitreous ngenye into. Utyando lwee-floaters lunokuba nemingcipheko ethile, enje ngezilonda kwi-retina kwaye zinganyangi onke amabala, yiyo loo nto isetyenziswa njenge isixhobo sokugqibela.
