Kunini lapho kufanele sikhathazeke ngalokhu?
Lena yingxenye ebaluleke kakhulu yalesi sihloko. Nakuba i-red reflex ivame ukuba uphawu olunempilo, uma ishintsha kancane , ingaba uphawu lwenkinga ethile ngaphakathi kweso. Odokotela bayakuhlola lokhu ukuze bathole ukuthi kukhona yini into efana naleyo kusenesikhathi.
Kunezinguquko ezimbalwa ezibalulekile okufanele uziqaphele. Ake sizibheke.
| Isici okufanele usiqaphele | Incazelo elula |
|---|---|
| Umbono omhlophe (i-Leukocoria) | Lesi yisibonakaliso esiyingozi kakhulu. Uma i-iris yeso ikhanya ngomhlophe, ophuzi, noma ngokukhanya esikhundleni sokubomvu, ibizwa ngokuthi i-leukocoria. Lokhu kusho ukuthi kukhona okuthile ngaphakathi kweso okuvimba ukukhanya ukuthi kungakhanyi. Akuvamile kakhulu, lokhu kungaba uphawu lwe- retinoblastoma, uhlobo lomdlavuza wamehlo olwenzeka ezinganeni. Luthinta cishe ingane eyodwa kwezingu-15,000. |
| Ubuthakathaka be-eye reflex | Ama-reflexes emehlweni womabili kufanele afane. Uma elinye iso libonakala licacile kanti elinye libonakala lifiphele, lokho kuyinto okufanele uyikhathalele. |
| I-reflex yeso elilodwa ayikho. | Uma iso elilodwa libomvu kakhulu kanti elinye iso limnyama ngokuphelele, lokho kusho ukuthi akukho ukusabela kulelo liso. Lokho kungaba yinkinga futhi. |
