Ngaba wakha wema phambi kwesibuko waza wakhanyisa ithotshi encinci elisweni lakho? Xa usenza njalo, uya kuqaphela ukuba isangqa esimnyama esiphakathi kweliso lakho, esibizwa ngokuba yi-pupil, siyaqina xa ukukhanya kukhanya kulo. Xa ukukhanya kususiwe, kuyakhula. Le yinkqubo eqhelekileyo emehlweni aphilileyo. Into ebalulekileyo kukuba xa ukukhanya kukhanya kwelinye iliso, umfundi emehlweni omabini kufuneka anciphe ngaxeshanye. Kodwa ngamanye amaxesha, iliso elinye lisenokungasabeli kakuhle kolu kukhanya. Yiloo nto siyibiza ngokuba yi-Marcus Gunn Pupil kwezonyango.
Ngamafutshane, yintoni uMarcus Gunn Pupil (RAPD)?
Kulungile, masiyibeke ngendlela elula le nto. Cinga ngamehlo akho njengabantu ababini abasebenza kunye. Ukukhanya luphawu oluvela entlokweni yakho (oko kukuthi, ingqondo yakho). Xa iliso elinye lifumana olu phawu, omabini amehlo kufuneka asebenzisane aze atyumze omabini amabala amnyama.
Kodwa xa ukukhanya kubetha iliso elichaphazelekayo lomntu oneMarcus Gunn Pupil, elo liso aliyifumani kakuhle umyalezo lize liwuthumele engqondweni. Ngenxa yoko, izangqa ezimnyama emehlweni omabini azinciphi kakuhle. Ngamanye amaxesha, endaweni yokuncipha, zinokubonakala ngathi zikhula kancinci.
Into ebalulekileyo kukuba uMarcus Gunn Pupil akasosifo ngokwaso. Luphawu olubaluleke kakhulu lokuba kukho ingxaki ngaphakathi kweliso lakho, ingakumbi kwi-retina okanye kwi-optic nerve. Ngoko ke, ukuba ubona olu phawu, kubalulekile ukufumana unobangela. Oogqirha bakwabiza olu phawu ngokuba yi-Relative Afferent Pupillary Defect (RAPD).
Kutheni oku kusenzeka? Zithini izizathu zoku?
Umfundi kaMarcus Gunn ubangelwa kakhulu kukonakala kwe-retina yakho okanye i-optic nerve, ethwala imiyalezo esuka elisweni ukuya engqondweni. Makhe sijonge iimeko eziphambili zonyango ezinokuchaphazela oku.
| Imeko | Ingcaciso elula |
|---|---|
| I-optic neuritis | Ukudumba okanye usulelo lwe-optic nerve. Le yimbangela eqhelekileyo ye-RAPD. |
| I-Glaucoma | Ukonakala kwe-optic nerve ngenxa yoxinzelelo oluphezulu ngaphakathi kweliso. Nangona kudla ngokuchaphazela omabini amehlo ngokulinganayo, i-RAPD inokwenzeka xa kuchaphazeleka amehlo angaphezu kwelinye. |
| Ukuqhekeka kwe-retinal | Ukuqhekeka kwe-retina kukwahlukana kwe-retina, i-membrane engaphakathi kweliso, kwizicubu ezixhasayo. Le yimeko enzulu kakhulu. |
| Ukuvaleka kwemithambo ye-retinal ephakathi ye-Ischemic | Ukuvaleka komthambo omkhulu ohambisa igazi kwi-retina. |
| Ukuwohloka kwamehlo | Ukonakala okungapheliyo kwi-optic nerve ngenxa yesizathu esithile. |
| Iithumba zamehlo | Ukucinezelwa kwemithambo-luvo ye-optic yizimila ezinomhlaza okanye ezingezizo umhlaza. |
| Ukulimala kwamehlo | Ukonakala kwemithambo-luvo okanye i-retina ngenxa yengozi enkulu, ukutsha, okanye usulelo. |
Ukongeza, uphawu lukaMarcus Gunn Pupil alunakubonwa kwiimeko ezinzima ze -amblyopia , okanye "iliso elivilaphayo," kunye ne -cataracts ezinzima.
Uyifumana njani le nto, Gqirha?
Le yinto ongayifumaniyo ekhaya. Kukho uvavanyo olukhethekileyo oluqhutywa ngugqirha. Lubizwa ngokuba yi-"Swinging flashlight test." Lukwabizwa ngokuba luvavanyo lweMarcus Gunn.
Oku kwenziwa ngolu hlobo:
1. Ugqirha uza kukusa kwigumbi elimnyama kancinci.
2. Emva koko, usebenzisa itotshi encinci, khanyisa ukukhanya kwiliso ngalinye imizuzwana embalwa.
3. Emva koko tshintshela isibane kwelinye iliso ngokukhawuleza.
4. Tshintshela isibane ngasemva nangaphambili ngolu hlobo izihlandlo ezimbalwa, ujonge ngononophelo ukuba zombini ii-peas zakho ezinamehlo amnyama zisabela njani ekukhanyeni ngendlela efanayo, okanye nokuba enye iziphatha ngendlela eyahlukileyo kwenye.
Kumntu ophilileyo, i-iris yamehlo omabini kufuneka inciphe kunye nanini na xa ukukhanya kumbetha. Nangona kunjalo, xa ukukhanya kuvuliwe kwiliso elichaphazelekayo lomntu one-RAPD, i-iris ayinciphisi kakuhle, kodwa ihlala ilingana ngobukhulu okanye ivuleke kancinci. Oku kwazisa ugqirha ukuba kukho ingxaki.
Inyangwa njani le meko?
Oku kubaluleke kakhulu ukukuqonda. Akukho nyango luthile lomfundi kaMarcus Gunn. Kuba ayisosifo. Unyango luhlala lujongana nemeko ebangela oko.
Umzekelo:
- Ukuba unobangela yi -optic neuritis , ugqirha wakho unokukunika amayeza anjenge-IV steroids.
- Ukuba unobangela yiglaucoma , amaconsi asemlonyeni aya kunikwa ukulawula uxinzelelo olusesweni.
- Ukuba unobangela kukuqhekeka kwe-retina , kunokufuneka iinkqubo ze-laser okanye utyando ukuze kulungiswe loo nto.
Ngoko ke, ugqirha wakho uza kuqala enze uvavanyo olufunekayo ukuze afumanise unobangela weRAPD. Emva koko, uza kucebisa unyango olungcono kuwe ngokusekelwe kuloo nto.
Ufanele uye nini kugqirha ngoko nangoko?
Ukubona ngamehlo yenye yezona zinto zixabisekileyo kuthi. Ngoko ke, musa ukulibala naluphi na utshintsho emehlweni akho. Ukuba unezinye zezi mpawu zilandelayo, qiniseka ukuba ubona ugqirha, ingakumbi ugqirha wamehlo.
- Intlungu okanye ukungakhululeki emehlweni .
- Umbono ofipheleyo okanye ukubona izinto zimbini.
- Ubunzima bokubona ebusuku .
- Ukubona izibane ezikhanyayo (ezikhanyayo) okanye izinto ezidadayo embonweni wakho.
- Inxalenye yentsimi yakho yokubona iba mnyama okanye ingabonakali.
Ukuba ufumana naziphi na kwezi mpawu, musa ukuzithatha njengento "encinci." Bonana nogqirha ngokukhawuleza. Kuba kwezi meko, okukhona uqala unyango ngokukhawuleza, kokukhona amathuba akho okusindisa ukubona kwakho ayanda.
Umyalezo Wokuya Ekhaya
- UMarcus Gunn Pupil (RAPD) ayisosifo, luphawu olubalulekileyo lwezonyango olubonisa ingxaki nge-optic nerve okanye i-retina yeliso lakho.
- Nangona olu phawu lodwa lungabangeli mngcipheko kwimpilo, imeko ebangela oku inokuba yingozi kwaye ifuna unyango.
- Ugqirha wakho angaxilonga le meko ngovavanyo olulula olubizwa ngokuba yi-"swinging flashlight test".
- Unyango alungolwesi sibonakaliso sikaMarcus Gunn Pupil, kodwa lulolwesi sifo esibangele esi sibonakaliso. Oku kungadinga amayeza, ilaser, okanye utyando.
- Ukuba ubona naluphi na utshintsho ekuboneni kwakho (iintlungu, ukufiphala, ukungaboni ebusuku), funa ingcebiso kagqirha ngokukhawuleza ngaphandle kokulibazisa.
