Chithunzi cha kumbuyo kwa maso anu? (Fundus Photography) Tiyeni tidziwe bwino lomwe chomwe chili!

Kodi munayamba mwadzifunsapo momwe dokotala wa maso amaonera zinthu zazing'ono koma zofunika kwambiri m'maso mwathu? Nthawi zina amaika mankhwala m'diso ndikupangitsa diso lakuda kuwoneka lalikulu, sichoncho? Chabwino, lero tikambirana za njira yomwe imajambula chithunzi chakumbuyo kwa diso, 'fundus'. Iyi ndi njira yomwe timayitcha ``Fundus Photography'' .

Kodi Kujambula Zithunzi za Fundus n'chiyani?

Mwachidule, ``(Fundus Photography)`` ndi pamene katswiri wa maso anu akujambula chithunzi cha khoma lakumbuyo la diso lanu, lomwe ndi gawo lomwe timalitcha kuti 'fundus'. Poyang'ana zithunzizi, dokotalayo amatha kuwona mbali zingapo za diso zomwe ndizofunikira kwambiri pakuwona kwanu. Iyi ndi njira yosavuta kwambiri, yosavulaza.

Kodi ziwalo zofunika kwambiri mkati mwa diso ndi ziti?

Pali nyumba zingapo zofunika kwambiri mkati ndi kumbuyo kwa maso athu. Zili ngati m'nyumba mwathu, chilichonse chili ndi malo akeake. Taganizirani izi, awa ndi malo akuluakulu:

• Retina: Iyi ndi gawo lomwe lili ndi maselo ozindikira kuwala, otchedwa photoreceptors. Maselo awa amatumiza zizindikiro ku ubongo zokhudzana ndi kuwala komwe amapeza. Ubongo umagwiritsa ntchito zizindikiro izi kuti upange chithunzi chachikulu chomwe "umawona."
• Macula: Iyi ndi gawo lodziwika bwino la retina yanu. Lili ndi ma photoreceptors omwe amakuthandizani kuwona mitundu ndi zinthu zazing'ono. Lili ngati kamera ya HD! Mukawerenga buku, macula imakuthandizani kuwona bwino zomwe zalembedwa.
• Mitsempha Yowona: Izi zili ngati 'chingwe cha data' chomwe chimalumikiza retina yanu ndi ubongo wanu. Matenda ambiri a maso amatha kukhudza gawo la mitsempha iyi yomwe imalumikizana ndi diso.
• Choroid: Chigawo ichi chili pansi pa retina yanu. Ndi gawo la pakati pa khoma lozungulira diso lanu lotchedwa uvea. Mitsempha yamagazi yomwe imapereka magazi ku retina yanu ili mu choroid.

Kodi mayeso ojambulira zithunzi a fundus amachitika liti?

Mayeso a ``Fundus Photography`` awa akhoza kuchitika ngati gawo la ``Routine Eye Exam`` yanu. Kapena, ngati muli ndi zizindikiro zilizonse za maso kapena kusintha kwa masomphenya, amagwiritsidwanso ntchito ngati gawo la mayeso apadera a maso kuti mupeze chomwe chikuyambitsa. Mayeso apadera ngati awa amathandiza kupeza zizindikiro zinazake za matenda a maso.

Tangoganizani, ndi m'mikhalidwe ngati iyi pamene madokotala nthawi zambiri amasankha kuchita mayeso a ``(Fundus Photography)``:

• Matenda a retina monga retinopathy yokhudzana ndi matenda a shuga kapena retinopathy yothamanga kwambiri.
• Kuvulala kapena kuwonongeka kwa retina, monga kung'ambika kapena kusweka kwa maso.
• Kusintha kwina kwa retina, monga kuwonongeka kwa macular kapena kutayika kwa mawonekedwe amitundu.
• Uveitis ndi matenda otupa omwe amakhudza retina kapena choroid.
• Matenda a mitsempha ya optic monga optic atrophy ndi papilledema.
• Kusintha kapena kuwonongeka kwa retina ndi/kapena mitsempha ya maso chifukwa cha matenda monga glaucoma.
• Zomwe zimayambitsa mawanga akuda (Scotomas) m'masomphenya kapena zolakwika m'munda wowona.
• Khansa ya maso ndi zotupa zomwe si khansa (zosavulaza), monga 'retinoblastoma'.
• Matenda omwe amapezeka m'diso, monga toxoplasmosis.

Kodi Fundus Photography imagwira ntchito bwanji?

Mayeso a ``(Fundus Photography)`` awa amachitika pogwiritsa ntchito ``(Fundus Camera)``. Zipatala zambiri za maso zili ndi chimodzi mwa zipangizo zapaderazi. Chabwino, tsopano tiyeni tiwone momwe makamera awa amaonekera.

Pali mitundu iwiri ikuluikulu ya makamera a fundus:

Makamera Okhazikika a Fundus

Chipangizochi chimaoneka ngati chubu cha telesikopu. Kumbali ina, pali chimango choti mugwire chibwano chanu ndi mphumi, ndipo kumbali inayo, pali lenzi yaying'ono kuti dokotala azitha kuwona, ndipo pali mabatani owongolera. Kuti mupeze zotsatira zabwino kuchokera ku makamera awa, dokotalayo adzayika madontho owonjezera maso anu musanayambe mayeso. Izi zidzakuthandizani kuwona bwino mkati mwa diso lanu.

Makamera Ogwiritsa Ntchito Laser Yaikulu

Makamera awa amagwiritsa ntchito ma laser apadera ndi njira zojambulira kuti ajambule zithunzi za fundus mwachangu, ngakhale maso anu sanakulidwe (monga popanda kugwiritsa ntchito mankhwala okulitsa diso). Komabe, zimakhala zosavuta kujambula zithunzi maso anu akakulidwa. Makamera awa nthawi zambiri amakhala ndi thumba limodzi lozungulira lomwe mungawone. Bowo limenelo lili pachivundikiro chachikulu, chachitali, komanso chathyathyathya. Malo ozungulira thumba limenelo nthawi zambiri amaphimbidwa ndi chivundikiro chofewa cha rabara, kotero chimakhala chomasuka ndipo sichimapweteka mukachigwira pankhope panu.

Kodi mungayembekezere chiyani musanayambe komanso panthawi ya mayeso?

Kodi muyenera kukonzekera mayeso asanayambe?

Ayi, mayeso awa a ``(Fundus Photography)`` sakufuna kukonzekera kwambiri. Palibe chodetsa nkhawa. Dokotala angakuikeni madontho a maso kuti akulitse mphete yakuda m'maso mwanu musanajambule zithunzi. Madontho awa amatenga mphindi zochepa kuti agwire ntchito. Muyenera kukhala oleza mtima kwa kanthawi.

Kodi chimachitika ndi chiyani panthawi ya mayeso?

Tsopano, takambirana za mitundu iwiri ya makamera a fundus. Chifukwa chake zomwe mukukumana nazo zidzadalira mtundu wa kamera yomwe dokotala amagwiritsa ntchito. Nthawi zina, n'zotheka kujambula zithunzi ndi mitundu yonse iwiri ya makamera.

Makamera Okhazikika a Fundus

Mukajambula zithunzi ndi chipangizochi, mumakhala pampando kapena mpando, moyang'anizana ndi chimango chomwe chili mbali yanu ya chubu. Dokotala adzatsuka mphumi ndi chibwano chanu ndi chopukutira asanakuike pankhope panu.

Ndikofunikira kwambiri kusunga chibwano chanu ndi mphumi yanu bwino bwino. Mwanjira imeneyi, zidzakhala zosavuta kwa dokotala kujambula zithunzi mwachangu. Mutu wanu ukakhazikika bwino, muyenera kuyang'ana mbali imodzi ya chubu. Mkati mwake, mudzawona kuwala kukuwala m'diso lanu.

Dokotala amakhala mbali ina ya chubu, akuyang'ana kudzera mu diso la kamera, amasintha kamera, ailoze pamalo enaake, ndikujambula zithunzi chimodzi ndi chimodzi. Amakuuzani kuti muyang'ane patsogolo, yang'anani kumanja, yang'anani kumanzere, ndi zina zotero. Kutengera chifukwa chojambulira zithunzi, amajambula zithunzi za diso limodzi kapena onse awiri. Zithunzi zikajambulidwa, mayeso amatha. Mwachangu, eti?

Makamera Ogwiritsa Ntchito Laser Yaikulu

Mukayang'ana m'chipinda chotseguka cha kamera yozungulira, mudzawona chizindikiro chozungulira, chomwe muyenera kuyang'ana molunjika. Kumbuyo kumbuyo kwa chizindikirocho kungasinthe mtundu. Dokotala kapena katswiri amene akuchita mayesowa adzakuuzani tanthauzo la mitunduyo, momwe mungayenderere, ndi zinthu zina zomwe ziyenera kujambulidwa pachithunzichi.

Mukafika pamalo oyenera, adzayatsa kamera. Mudzawona kuwala kobiriwira kowala, ngati kuwala pa pepala mkati mwa chojambulira, kudutsa m'maso mwanu. Kumangokhala kanthawi kochepa, pafupifupi sekondi imodzi. Musadandaule, sikupweteka. Nthawi zambiri, zithunzi zitatu zimajambulidwa pa diso lililonse. Zithunzi zikajambulidwa, mayeso amatha.

Kodi chimachitika ndi chiyani pambuyo pa mayeso?

Pambuyo pojambula zithunzi za fundus, dokotala kapena namwino adzakutengerani ku chipinda choyezera. Kumeneko mudzakumana ndi dokotala wa maso kapena wa maso. Iwo adzayesanso zina zonse, kapena adzayang'ana zithunzi za fundus yanu ndikufotokozera tanthauzo lake.

Kodi pali zoopsa kapena zotsatirapo zilizonse pa mayesowa?

Kuyesa uku (Fundus Photography) ndi kotetezeka kwambiri . Palibe zotsatirapo zake. Komabe, ngati mupatsidwa mankhwala okulitsa diso lanu (`(Dilation ya Maso`), mankhwalawa angayambitse zotsatirapo zazing'ono. Mwachitsanzo, maso anu akhoza kukhala osawoneka bwino kwa kanthawi, ndipo maso anu angawoneke abuluu kunja. Koma nthawi zambiri izi zimakhala zazing'ono kwambiri ndipo zidzachira pakapita kanthawi. Ngati dokotala wanu wakulitsa maso anu, maso anu adzakhalabe otambasuka mpaka mankhwalawo atatha. Nthawi zambiri, mankhwalawa amatha pakatha maola ochepa (dokotala wanu adzakuuzani nthawi yeniyeni yomwe idzatenge).

Ngati muli ndi mantha okhudza kuwala kwa dzuwa, zomwe zikutanthauza kuti maso anu amasanduka abuluu mukakhala panja, mungamve kusasangalala pang'ono kuwala kukakugundani m'maso mukajambula zithunzi. Izi nthawi zambiri zimakhala zakanthawi kochepa, ndipo dokotala wanu adzakuthandizani pa izi. Zipinda zambiri zoyezera maso zimakhala ndi magetsi ofooka, kotero ngati simukusangalalabe ndi kuwala kowala, dokotala wanu adzagwiritsa ntchito kuwalako.

Kodi ndingathe kuyendetsa galimoto nditatenga zithunzi za fundus?

Inde, nthawi zambiri mutha kuyendetsa galimoto popanda vuto lililonse mutatha kuchita ``(Fundus Photography)``. Zimatengera chifukwa chomwe mudajambulira zithunzi, momwe maso anu alili musanayesedwe, ndi zina zingapo.

Anthu ambiri amayendetsa galimoto kupita ku ofesi ya dokotala, ndipo inu mukhoza kubwerera mukamaliza mayeso. Ngati dokotala wakulitsa maso anu (anagwiritsa ntchito mankhwala okulitsa maso anu), angakupatseni zophimba zotayidwa zomwe mungathe kuvala ngati magalasi a dzuwa. Izi ndi zabwino kwa maso anu mukatuluka. Ngati muvala magalasi, mutha kusiya zophimba zotayidwa izi pamwamba pa magalasi anu mpaka kukula kwake kutatha. Komabe, ngati simukudziwa, ndi bwino kufunsa dokotala wanu musanayendetse galimoto.

Kodi zotsatira zake zimakhala bwanji? Kodi zikutiuza chiyani?

Makamera a fundus m'zipatala zambiri za maso amatha kutumiza zithunzi ku kompyuta yomwe ili m'chipinda choyezetsera matenda akangotengedwa. Dokotala wanu amatha kuwona zithunzizo pa sikirini ya kompyuta. Angakuwonetseninso zithunzizo ndikufotokozera zinthu zosiyanasiyana zomwe zikuwonetsa. Anganene zinthu monga, "Yang'anani mitsempha ya maso mkati mwa diso lanu..."

Ngati fundus ya diso lanu ikuwoneka bwino, dokotala wanu adzakuuzani zimenezo. N'zolimbikitsa kumva mawu ngati akuti , "Palibe cholakwika, chilichonse chili bwino." Ngati zithunzizo zikusonyeza kusintha kulikonse kwakukulu kapena zolakwika, dokotala wanu adzakufotokozerani. Ngati dokotala wanu ali ndi zithunzi zanu zakale, akhoza kuziyerekeza. Iye anganene zinthu monga, "Pali kusiyana pang'ono ndi nthawi yapitayi."

Kutengera ndi zomwe tikuwona pazithunzi zaposachedwa, akhoza kukhala akuchita chimodzi kapena zingapo mwa izi:

• Alimbikitseni mayeso ena (monga, scan ina yapadera)
• Amapereka njira zina zochizira (monga mankhwala, chithandizo cha laser)
• Padzakonzedwa nthawi yokumananso ndi munthu wina. (Chitsanzo: Tionanenso pakatha miyezi itatu)
• Mudzatumizidwa kwa katswiri wina (monga katswiri wa matenda a shuga).

Pali mwambi wakuti, ‘Chithunzi chili ndi mawu ambiri.’ Mofanana ndi zimenezi, chithunzi chomwe chili kumbuyo kwa maso anu n’chamtengo wapatali pa thanzi la maso anu.

Pomaliza, kumbukirani izi.

Kotero, `(Fundus Photography)` iyi ndi mayeso ofunika kwambiri kuti muwone thanzi la maso anu. Katswiri wanu wa maso angagwiritse ntchito zithunzizi kuti awone ngati maso anu ali bwino komanso kuti adziwe mavuto aliwonse. Chabwino kwambiri ndichakuti mayeso awa `(Fundus Photography)` amatha kuwona kusintha mkati mwa diso musanawonetse zizindikiro zilizonse. Iyi ndi gawo la mayeso a maso wamba. Nthawi zina, imatha kuzindikira matenda omwe amayamba mkati mwa diso popanda inu kuzindikira.

Kotero, mutha kufunsa dokotala wanu kuti akupatseni zambiri za momwe izi zingakuthandizireni. Musaiwale kuti ndi udindo wanu kuteteza maso anu! Ndikofunikira kwambiri kupita kukayezetsa maso nthawi zonse .
