Wake wema phambi kwesibuko wakhanyisa ithoshi elincane esweni lakho? Uma wenza kanjalo, uzobona ukuthi indilinga encane emnyama ephakathi kweso lakho, ebizwa ngokuthi umfundi, iyaqina lapho ukukhanya kukhanya kulo. Uma ukukhanya kususwa, kuyavuleka. Lena inqubo evamile emehlweni aphilile. Into ebalulekile ukuthi lapho ukukhanya kukhanya esweni elilodwa, umfundi kuwo womabili amehlo kufanele afinyele ngesikhathi esisodwa. Kodwa ngezinye izikhathi, iso elilodwa lingase lingasabeli kahle kulokhu kukhanya. Yilokho esikubiza ngokuthi umfundi wezokwelapha uMarcus Gunn.
Kalula nje, uyini uMarcus Gunn Pupil (RAPD)?
Kulungile, ake sikubeke ngendlela elula lokhu. Cabanga ngamehlo akho njengezisebenzi ezimbili ezisebenza ndawonye. Ukukhanya kuyisibonakaliso esivela ekhanda lakho (okungukuthi, ebuchosheni bakho). Uma iso elilodwa lithola lesi sibonakaliso, womabili amehlo kumele asebenzisane futhi achoboze womabili ama-blackhead.
Kodwa uma ukukhanya kushaya iso elithintekile lomuntu one-Marcus Gunn Pupil, lelo so lingalitholi kahle umlayezo bese liwuthumela ebuchosheni. Ngenxa yalokho, imibuthano emnyama emehlweni womabili ayinciphi kahle. Ngezinye izikhathi, esikhundleni sokuncipha, ingase ibonakale ikhula kancane.
Into ebalulekile ukuthi uMarcus Gunn Pupil akasona isifo ngokwaso. Kumane kuyisibonakaliso esibaluleke kakhulu sokuthi kunenkinga ngaphakathi kweso lakho, ikakhulukazi ku-retina noma ku-optic nerve. Ngakho-ke, uma ubona lesi sibonakaliso, kubalulekile ukuthola imbangela. Odokotela babiza lesi sibonakaliso ngokuthi i-Relative Afferent Pupillary Defect (RAPD).
Kungani lokhu kwenzeka? Yiziphi izizathu zalokhu?
Umfundi kaMarcus Gunn ubangelwa kakhulu ukulimala kwe-retina yakho noma i-optic nerve, ethwala imiyalezo esuka esweni iye ebuchosheni. Ake sibheke izimo zezokwelapha eziyinhloko ezingathinta lokhu.
| Isimo | Incazelo elula |
|---|---|
| I-optic neuritis | Ukuvuvukala noma ukutheleleka kwe-optic nerve. Lokhu kuyimbangela evamile kakhulu ye-RAPD. |
| I-Glaucoma | Ukulimala kwe-optic nerve ngenxa yokucindezela okukhulu ngaphakathi kweso. Nakuba kuvame ukuthinta womabili amehlo ngokulinganayo, i-RAPD ingenzeka uma kuthinteka amehlo angaphezu kwelilodwa. |
| Ukuhlukaniswa kwe-retinal | Ukuhlukaniswa kwe-retinal ukuhlukaniswa kwe-retina, ulwelwesi olungaphakathi kweso, nezicubu ezisekelayo. Lesi yisimo esibi kakhulu. |
| Ukuvaleka kwemithambo ye-retinal ephakathi kwe-Ischemic | Ukuvaleka komthambo omkhulu ohambisa igazi ku-retina. |
| Ukuwohloka kwamehlo | Ukulimala unomphela kwe-optic nerve ngenxa yesizathu esithile. |
| Izimila zamehlo | Ukucindezelwa kwenzwa ye-optic yizimila ezinomdlavuza noma ezingezona umdlavuza. |
| Ukulimala kwamehlo | Ukulimala kwe-optic nerve noma i-retina ngenxa yengozi enkulu, ukusha, noma ukutheleleka. |
Ngaphezu kwalokho, isici sikaMarcus Gunn Pupil asivamile ukubonakala ezimweni ezimbi kakhulu ze- amblyopia , noma "iso elivilaphayo," kanye ne-cataracts ezinzima.
Ukuthola kanjani lokhu, Dokotela?
Lokhu kuyinto ongayitholi ekhaya. Kukhona ukuhlolwa okukhethekile okwenziwa udokotela ngalokhu. Kubizwa ngokuthi "ukuhlolwa kwethoshi elijikayo." Kubizwa nangokuthi ukuhlolwa kukaMarcus Gunn.
Lokhu kwenziwa kanje:
1. Udokotela uzokuhambisa ekamelweni elimnyama kancane.
2. Bese, usebenzisa ithoshi elincane, khanyisa ukukhanya esweni ngalinye imizuzwana embalwa.
3. Bese ushintshela ngokushesha isibani kwelinye iso.
4. Shintsha isibani siye emuva naphambili kanje izikhathi ezimbalwa, ubheke ngokucophelela ukuthi ubhontshisi wakho onamehlo amnyama womabili usabela kanjani ekukhanyeni ngendlela efanayo, noma ukuthi omunye uziphatha ngendlela ehlukile komunye.
Kumuntu ophilile, i-iris yamehlo womabili kufanele inciphe ndawonye noma nini lapho ukukhanya kumthinta. Kodwa-ke, uma ukukhanya kuvuliwe esweni elithintekile lomuntu one-RAPD, i-iris ayinciphi kahle, kodwa ihlala ilingana ngobukhulu noma ivuleka kancane. Lokhu kwazisa udokotela ukuthi kunenkinga.
Lesi simo selashwa kanjani?
Lokhu kubaluleke kakhulu ukukuqonda. Akukho ukwelashwa okuqondile komfundi kaMarcus Gunn. Ngoba akusona isifo. Ukwelashwa kuhlale kulungisa isimo esiyisisekelo esibangele lesi sifo.
Ngokwesibonelo:
- Uma imbangela kuyi- optic neuritis , udokotela wakho angase akunike imithi efana ne-IV steroids.
- Uma imbangela kuyi -glaucoma , amaconsi amehlo azonikezwa ukulawula ingcindezi esweni.
- Uma imbangela iwukuhlukana kwe-retinal , kungase kudingeke izinqubo ze-laser noma ukuhlinzwa ukuze kulungiswe lokhu.
Ngakho-ke, udokotela wakho uzokwenza izivivinyo ezidingekayo kuqala ukuze athole imbangela eqondile ye-RAPD. Ngemuva kwalokho, uzosikisela ukwelashwa okungcono kakhulu kuwe ngokusekelwe kuleso sizathu.
Kufanele ubonane nodokotela ngokushesha nini?
Ukubona amehlo kungenye yezinto zethu eziyigugu kakhulu. Ngakho-ke, ungashayi indiva noma yiziphi izinguquko emehlweni akho. Uma unezinye zezimpawu ezilandelayo, qiniseka ukuthi ubona udokotela, ikakhulukazi udokotela wamehlo.
- Ubuhlungu noma ukungakhululeki kwamehlo .
- Ukubona izinto ngendlela efiphele noma ukubona izinto njengezimbili.
- Ubunzima bokubona ebusuku .
- Ukubona izibani ezikhanyayo (ezikhanyisayo) noma izinto ezintantayo embonweni wakho.
- Ingxenye yensimu yakho yokubona iba mnyama noma ingabonakali.
Uma uhlangabezana nanoma yiziphi zalezi zimpawu, ungazinaki njengezinto "ezincane nje." Bonana nodokotela ngokushesha okukhulu. Ngoba kulezi zimo, uma uqala ukwelashwa ngokushesha, amathuba akho okusindisa amehlo akho ayanda.
Umlayezo Wokuya Nawe Ekhaya
- UMarcus Gunn Pupil (RAPD) akusona isifo, kuyisibonakaliso esibalulekile sezokwelapha esibonisa inkinga nge-optic nerve noma i-retina yeso lakho.
- Nakuba lesi sibonakaliso sodwa singabangeli ingozi empilweni, isimo esiyisisekelo esibangela lokhu singaba sibi kakhulu futhi sidinga ukwelashwa.
- Udokotela wakho angaxilonga lesi simo ngokuhlola okulula okubizwa ngokuthi "ukuhlolwa kwethoshi elijikayo."
- Ukwelashwa akusikho okwesibonakaliso somfundi we-Marcus Gunn, kodwa okwesimo esiyisisekelo esibangele lesi sibonakaliso. Lokhu kungadinga imithi, i-laser, noma ukuhlinzwa.
- Uma ubona noma yiziphi izinguquko ekuboneni kwakho (ubuhlungu, ukufiphala, ubumpumputhe basebusuku), funa iseluleko sezokwelapha ngokushesha ngaphandle kokulibala.
