Uila uila

ʻO ka electroretinography kahi hoʻāʻo e ana i ka pane uila o nā huna uila māmā o ka maka, i kapa ʻia nā koʻokoʻo a me nā ʻone. ʻO kēia mau ʻāpana kahi ʻāpana o ka retina (ka ʻaoʻao hope o ka maka).

ʻOiai ʻoe e noho ana, hoʻonohonoho ka mea mālama ola i nā kulu numbing i loko o kou mau maka, no laila ʻaʻole ʻoe e hōʻoluʻolu i ka wā o ka hoʻāʻo. Mālama ʻia kou mau maka me kahi mea liʻiliʻi i kapa ʻia he speculum. Kau ʻia ka mea uila uila (electrode) i kēlā me kēia maka.

Ana ka uila i ka hana uila o ka retina i ka pane o ke kukui. ʻĀlohilohi kahi kukui, a hele ka pane uila mai ka electrode i kahi pale TV-like, kahi e hiki ai ke nānā a hoʻopaʻa ʻia. ʻO ke kumu pane maʻamau he mau nalu i kapa ʻia A a me B.

Lawe ka mea hāʻawi i nā heluhelu i ka mālamalama o ka lumi maʻamau a laila hoʻi i ka pōʻeleʻele, ma hope o ka ʻae ʻana i 20 mau minuke no kou mau maka e hoʻoponopono.

ʻAʻole pono kahi hoʻomākaukau kūikawā no kēia hōʻike.

ʻO nā kuʻi e kau ana ma kou maka ke ʻano wīwī paha. Hoʻokahi paha hola e hoʻāʻo ai ka hōʻike.

Hana ʻia kēia hōʻike e ʻike i nā maʻi o ka retina. He mea pono nō hoʻi ia no ka hoʻoholo ʻana inā paipai ʻia ke ʻoki retina.

E hōʻike nā hopena hōʻike maʻamau i kahi kumu A a me B maʻamau i ka pane ʻana i kēlā me kēia uila.

Hiki i nā kūlana aʻe ke kumu i nā hopena maikaʻi ʻole:

• ʻO Arteriosclerosis me ka hōʻino ʻia o ka retina
• Makapo makapō Congenital
• ʻO Congenital retinoschisis (ka hoʻokaʻawale ʻana i nā papa retina)
• Arteritis pūnana nui
• Nā Lapaʻau (chloroquine, hydroxychloroquine)
• Mucopolysaccharidosis
• Wehe retina
• Rod-cone dystrophy (retinitis pigmentosa)
• Trauma
• Ka hemahema o ka wikamina A

Hiki i ke kōkō ke kiʻi i kahi ʻiʻo manawa ma ka ʻili mai ka uila. Inā ʻole, ʻaʻohe pilikia me kēia kaʻina hana.

ʻAʻole pono ʻoe e hamo i kou mau maka no hoʻokahi hola ma hope o ka hoʻāʻo ʻana, no ka mea he mea ʻeha kēia i ka ʻili. E kamaʻilio kāu mea lawelawe iā ʻoe e pili ana i nā hopena o ka hoʻāʻo a me ke ʻano o lākou no ʻoe.
