ʻO ka ultrasound maka a me orbit

ʻO kahi ultrasound e nānā ai ka maka a me ka orbit e nānā i ka maka o ka maka. Ana nō hoʻi ia i ka nui a me nā hanana o ka maka.

Hana pinepine ʻia ka hoʻāʻo ma ke keʻena o ka ophthalmologist a i ʻole ke keʻena ophthalmology o kahi haukapila a haukapila paha.

Pōpō kou maka me ka lāʻau (anesthetic drop). Hoʻokomo ʻia ke kani ultrasound (transducer) i mua o ka maka o ka maka.

Hoʻohana ka ultrasound i nā nalu kani kani pinepine e hele ma waena o ka maka. Nā hiʻohiʻona (echo) o nā nalu kani i ke kiʻi o ke ʻano o ka maka. Ma kahi o 15 mau minuke ka hoʻāʻo.

Aia he 2 ʻano o ka scans: A-scan a me B-scanner.

No ka A-scan:

• Noho pinepine ʻoe ma ka noho a kau i kou auwae ma ka maha o ka auwae. E nānā pono ʻoe i mua.
• Kau ʻia kahi ʻimi liʻiliʻi i mua o kou maka.
• E hana pū ʻia paha ka hōʻike me ʻoe e moe ana i hope. Me kēia hana, kau ʻia kahi kīʻaha piha wai i kou maka e hana i ka hoʻāʻo.

No ka B-scan:

• Noho ʻoe a noi ʻia ʻoe e nānā i nā ʻaoʻao he nui. Hana pinepine ʻia ka hōʻike me ka maka o kou mau maka.
• Kau ʻia kahi gel ma ka ʻili o kou mau lihilihi. Hoʻokomo mālie ʻia ka probe B-scan i kāu lihilihi e hana ai i ka hōʻike.

ʻAʻole pono kahi hoʻomākaukau kūikawā no kēia hōʻike.

Kuhi ka maka o kou maka, no laila ʻaʻole pono ʻoe e hōʻoluʻolu ʻole. E noi paha ʻoe e nānā i nā ʻaoʻao ʻokoʻa e hoʻomaikaʻi i ke kiʻi ultrasound a i ʻole hiki iā ia ke ʻike i nā wahi like ʻole o kou maka.

E holo paha i lalo kou papalina i ka gel i hoʻohana ʻia me ka B-scan, akā ʻaʻole ʻoe e ʻike i kahi ʻoluʻolu a i ʻole ʻeha.

Pono paha ʻoe i kēia hōʻoia inā loaʻa ʻoe i ka cataract a i ʻole nā ​​pilikia maka ʻē aʻe.

Ana kahi ultrasound A-scan i ka maka e hoʻoholo ai i ka mana kūpono o ke aniani implant ma mua o ke kaha ʻana o ka cataract.

Hana ʻia kahi B-scan e nānā i ka ʻaoʻao i loko o ka maka a i ʻole ke ākea ma hope o ka maka i hiki ʻole ke ʻike pololei ʻia. Hiki paha kēia ke loaʻa ʻoe i nā cataract a i ʻole nā ​​kūlana ʻē aʻe paʻakikī i ka kauka e ʻike ai i ka hope o kou maka. Hiki i ke hōʻike ke kōkua i ke kuhi ʻana i ka retinalment retinalment, tumors, a i ʻole nā ​​maʻi ʻē aʻe.

No ka A-scan, aia nā ana o ka maka i ka pae maʻamau.

No ka B-scan, ʻike ʻia nā hanana o ka maka a me ka orbit i maʻamau.

Hōʻike kahi B-scan:

• Kahe i loko o ka gel maopopo (vitreous) e hoʻopiha i ka hope o ka maka (vitreous hemorrhage)
• Ka maʻi ʻaʻai o ka retina (retinoblastoma), ma lalo o ka retina, a i ʻole nā ​​ʻāpana ʻē aʻe o ka maka (e like me melanoma)
• Nā mea i hōʻino ʻia a i ʻole nā ​​ʻeha i ke kumu iwi (orbit) e hoʻopuni a pale i ka maka
• Nā kino haole
• Ke huki nei i ka retina mai ka hope o ka maka (retina detachment)
• Pehu (pehu)

I mea e ʻānai ʻole ai i ke kornea, mai hamo i ka maka numbed a pau ka anesthetic (ma kahi o 15 mau minuke). ʻAʻohe mea ʻino ʻē aʻe.
