Iyo retina ndiyo yakajeka-inonzwika tambo yetishu kumashure kweziso reziso. Mifananidzo inouya kuburikidza nelensi yeziso yakanangiswa pane iyo retina. Iyo retina inozoshandura iyi mifananidzo kuita zviratidzo zvemagetsi uye ndokuitumira pamwe chete nemaziso e-optic kuuropi.

Iyo retina inowanzo tarisa yakatsvuka kana orenji nekuti kune yakawanda mitsipa yeropa kumashure kwayo. An ophthalmoscope inobvumidza mupi wezvehutano kuti aone kuburikidza nemudzidzi wako uye lens kune iyo retina. Dzimwe nguva mapikicha kana zviyero zvakasarudzika zveiyo retina zvinogona kuratidza zvinhu izvo mupi zvaasingakwanise kuona nekungotarisa kune iyo retina kuburikidza neophthalmoscope. Kana mamwe matambudziko eziso achivhara maonero emupi weiyo retina, ultrasound inogona kushandiswa.

Chero ani anosangana nematambudziko ekuona aya anofanirwa kuongororwa retinal:

• Shanduko mukupinza kwechiono
• Kurasikirwa kwemavara ekuona
• Kupenya kwechiedza kana kuyangarara
• Kuonekwa kwakatsauka (mitsara yakatwasuka inotarisa wavy)

• Ziso
