Kukho utshintsho olubalulekileyo ekufuneka luqwalaselwe. Makhe sijonge kulo.
| Uphawu ekufuneka luqwalaselwe | Intsingiselo nje |
|---|---|
| Umbono omhlophe (iLeukocoria) | Olu lolona phawu luyingozi kakhulu. Ukuba i-iris yeliso ikhanya ngomhlophe, ngomthubi, okanye ngokukhanya endaweni yokuba bomvu, ibizwa ngokuba yi-leukocoria.

Ichaphazela malunga nomntwana omnye kwabayi-15,000. |
| Ubuthathaka be-eye reflex | Ii-reflexes zamehlo omabini kufuneka zifane. Ukuba elinye iliso libonakala licacile kwaye elinye libonakala lifiphele, naleyo yinto ekufuneka uyixhalabele. |
| Akukho i-reflex yeliso elinye. | Ukuba elinye iliso libomvu kwaye elinye iliso limnyama ngokupheleleyo, oko kuthetha ukuba akukho reflex kwelo liso. Oko kungaba yingxaki. |
