Amehlo ethu ayindalo emangalisayo, akunjalo? Sibona kwaye sinamava ehlabathi ngezi zitho zimbini zincinci. Kodwa kungakanani esikwaziyo malunga namalungu amancinci angaphakathi kweliso esingenakukubona ngaphandle, kodwa enza umsebenzi omninzi obalulekileyo? Iliso ngokwenene liqoqo lamalungu amaninzi amancinci asebenzisanayo. Namhlanje siza kuthetha ngeqhawe elibaluleke kakhulu, kodwa elingaziwayo, elithuleyo ngaphakathi kweliso. Lowo ngumzimba we-ciliary.
Yintoni iCiliary Body?
Kulungile, masiqale ngokulula. Xa ujonga iliso lakho esipilini, ubona indawo enemibala, akunjalo? Abanye abantu balibona limnyama, abanye balibona limdaka. Silibiza ngokuba yi-iris. Lo mzimba we-ciliary usemva kwe-iris. Oko kuthetha ukuba asinakuyibona ngokuthe ngqo.
Ukuze ukuqonde ngcono oku, cinga ngale ndlela. Ngaphakathi kwamehlo ethu, kukho inwebu ekhethekileyo ebizwa ngokuba yi-uvea . Le yingqokelela yamacandelo amathathu. Kufana nokuba namagama amathathu eendawo ezintathu kwindlela enye.
1. I-Iris: Le yinxalenye enemibala yeliso. Ilawula ubungakanani bokukhanya okungena kweliso.
2. Umzimba weCiliary: Le yinxalenye elandelayo eqhagamshelwe kwi-iris.
3. I-Choroid: Le yinethiwekhi yemithambo yegazi ekwicala elingasemva kweliso. Ngumthombo ophambili wesondlo selihlo.
Zonke ezi nxalenye zintathu ziyadibana ukuze zenze i-uvea. Ngoko ke umzimba we-ciliary yinxalenye ebaluleke kakhulu ye-uvea.
Yeyiphi inkonzo ebonakalayo kweli candelo lincinci?
Nangona oku kuncinci, umsebenzi ewenzayo awuncinci. Umzimba we-ciliary unemisebenzi emibini ephambili.
1. Velisa ulwelo olufunekayo liliso
Ngaphakathi kwamehlo ethu kukho ulwelo olucacileyo olubizwa ngokuba yi-aqueous humor . Lufana nebhaluni egcwele umoya. Olu lwelo lunika iliso uxinzelelo olufunekayo kwaye luligcine likwimo entle. Kufana nokukhupha itayara yemoto. Ukuba uxinzelelo luyancipha, iliso linokuncipha, kwaye ukuba luyanda, iliso linokonakala.
Olu lwelo lubaluleke kakhulu luveliswa ngumzimba we-ciliary. Ayipheleli apho, kodwa lolu lwelo lukwabonelela ngesondlo esifunekayo kwilensi nakwi-cornea, i-membrane ecacileyo engaphambili kweliso. Ngoko ke, ngaphandle kolu lwelo, iliso alinakuhlala liphilile.
2. Ukukunceda ubone izinto ngokucacileyo (Ukugxila)
Le yeyona nto imangalisayo emzimbeni we-ciliary. Khawuthelekelele ufunda incwadi. Emva koko ngequbuliso ujonga phezulu ubone i-squirrel ebaleni. Emva koko ujonga incwadi kwakhona. Ngalo lonke ixesha ubona ngokucacileyo, ngaphandle kokufiphala, akunjalo?
Isizathu esiphambili soku yi-ciliary body. Isebenza ngolu hlobo:
- Xa ujonge ngokusondeleyo:Xa ujonge into ekufutshane, efana nencwadi, izihlunu zomzimba we-ciliary ziyaqina (ziyaqina). Oku kubangela ukuba ilensi yeliso ibe yi-convex, nto leyo ethetha ukuba iba nkulu kancinci.
- Xa ujonge into ekude: Xa ujonge into ekude, ezo zihlunu ziyakhululeka, kwaye ilensi yeliso iyathamba.
Omnye umsebenzi ophambili womzimba we-ciliary kukunceda ekugxileni ukukhanya okuvela kwinto esiyijongileyo ngokutshintsha imo yelensi. Izakhiwo ezincinci ezifana nomsonto ezibizwa ngokuba zii-zonular fibers nazo ziyanceda kulo msebenzi.
Ixesha elininzi, emva kweminyaka engama-40-45 ubudala, ukubona kwethu kufutshane kuya kufiphala kancinci, akunjalo? Kuba nzima ukufunda iphephandaba okanye ukujonga ifowuni. Oku sikubiza ngokuba yi- presbyopia . Esinye sezizathu zoku kukuba ukusebenza kwemisipha emzimbeni we-ciliary kuya kuba buthathaka njengoko sikhula.
Injani le ciliary body?
Njengoko besitshilo ngaphambili, oku kungasemva kwe-iris, ngoko ke asinakukubona ngaphandle. Kodwa xa uyijonga ngezixhobo ezikhethekileyo, ifana nesangqa. Ikwanazo neendawo ezinamaza, ezigobileyo. Sizibiza ngokuba ziinkqubo ze-ciliary . I-aqueous humor esiyikhankanyileyo ngaphambili ikhutshwa zezo ndawo zinamaza.
Ngokuphathelele umbala, inxalenye engaphandle yomzimba we-ciliary imnyama ngombala, ngelixa icala elingaphakathi licacile kwaye lingenambala.
Ziziphi izifo ezichaphazela umzimba we-ciliary?
Njengayo yonke inxalenye yomzimba wethu, umzimba we-ciliary unokuchaphazeleka ziimeko ezahlukeneyo zempilo. Nazi ezinye zazo.
Ukudumba kunye neentsholongwane
Ukudumba kwe-uvea kudla ngokubizwa ngokuba yi-uveitis . Ekubeni umzimba we-ciliary uyinxalenye ye-uvea, i-uveitis inokuchaphazela nomzimba we-ciliary. Ukuba ayinyangwa, ngamanye amaxesha inokukhokelela ekulahlekelweni kokubona.
Kukwakho nemeko yokudumba echaphazela zombini iris kunye nomzimba weciliary, ebizwa ngokuba yi -iridocyclitis . Oku kunokubangelwa zizifo ezahlukeneyo, ezinye iimeko zonyango ezifana ne-arthritis, okanye ngamanye amaxesha ngaphandle kwesizathu konke konke.
Iithumba kunye namaQela
Zombini iithumba ezingezizo umhlaza kunye nezo zingengomhlaza zinokukhula ngaphakathi kweliso. Ii-Adenomas ziithumba ezincinci, ezingezizo umhlaza. Nangona kunjalo, ngamanye amaxesha zinokuba ngumhlaza.
I-Intraocular MelanomaLolona hlobo luqhelekileyo lomhlaza wamehlo kubantu abadala. Kodwa lukwanqabile kakhulu. Ludla ngokuqala kwi-choroid, kodwa lunokusasazeka nakwi-ciliary body.
Ezinye Iimeko
Ukongeza koku, umzimba we-ciliary unokonakala ngenxa yezinye izizathu ezininzi.
- I-Glaucoma: Siyazi ukuba umzimba we-ciliary unoxanduva lokuvelisa i-aqueous humor elisweni. Ukuba ngesizathu esithile le aqueous humor ivaliwe ukuba ingaphumi elisweni, uxinzelelo olungaphakathi kweliso luyanda kakhulu. Oku sikubiza ngokuba yi-glaucoma.
- Ukulimala Kwamehlo: Umzimba we-ciliary ungonakaliswa okanye ususwe kwindawo yawo (ukuhlukana) yinto efana nengozi yemoto okanye into edibene nekhemikhali engene elisweni.
- I-Coloboma: Le yimeko yokuzalwa apho inxalenye yezicubu zamehlo ingekho. Le meko inokuchaphazela nomzimba we-ciliary.
- I-Optic Atrophy: Le yimeko ebangelwa kukonakala kwe-optic nerve. Ngamanye amaxesha inokuba luphawu lwenye ingxaki ngaphakathi kweliso.
Zithini iimpawu ukuba unengxaki enjalo?
Ukuba unemeko enxulumene nomzimba we-ciliary, unokufumana enye okanye ngaphezulu kwezi mpawu. Ukuba unayo nayiphi na kwezi mpawu, kufuneka ubone ugqirha ngokukhawuleza .
