Kei te kite koe i ngā ira pango, i ngā tukutuku rānei e rere ana i mua i ō kanohi? Kei te kite koe i te māramatanga? Me ako tātou mō te Wehenga o te Kiriata o Muri iho!

Kia ora! Kua kite koe i ngā ira pango iti, i ngā mea rite ki te tukutuku pungawerewere , i ngā mea rite ki te makawe iti e rere ana i mua i ō kanohi? I ētahi wā ka kite koe i te mura o te mārama mai i te kokonga o tō kanohi, tika? He tino whakararuraru ēnei. He tokomaha te hunga e wehi ana i tēnei. Nō reira, ki te mea kua pā tēnei ki a koe, me kōrero tātou i tēnei rā mō te take, he morearea, me te aha hoki e taea te mahi. Ko te āhuatanga ka kōrerohia e tātou ko te Posterior Vitreous Detachment , te PVD rānei.

He aha tēnei 'Wetewetenga o te Kiriata o Muri'?

He māmā noa iho, he rite tō tātou kanohi ki tētahi pōro iti. Kei roto i tēnei pōro he mea whakakīia ki tētahi mea rite ki te tiēre . Ka kiia tēnei ko te tiēre vitreous . Mā tēnei tiēre e hoatu te āhua porowhita ki te kanohi, e tiaki hoki i ngā mea ngawari o roto i te kanohi. Kei muri o te kanohi tētahi paparanga io tino angiangi, tino tairongo. Ka kiia ko te retina . He rite tana mahi ki te kiriata i roto i te kāmera. Ka hangaia ngā whakaahua e kitea ana e tātou ina tau te mārama ki runga i tēnei retina.

Nā, ko te PVD te wā e angiangi haere ana te kiriuhi vitreous i roto i te kanohi, e whakaiti ana , e wehe ana i te retina i muri iho. Whakaarohia he rite ki te mea rite ki te tiēre e angiangi haere ana, ā, e wehe pōturi ana i te pakitara. He tukanga taiao tēnei e tupu pinepine ana i a tātou e pakeke haere ana.

Ina wehea tēnei tiēre mai i te retina, e ai ki taku kōrero i mua ake nei, ka tīmata ngā atarangi pango, hina, ngā ira iti, me ngā mea rite ki te noke ki te rere i mua i ngā kanohi. Ka taea e ētahi tāngata te kite i te mārama i te kokonga o ō rātou kanohi. E whā ki te ono wiki pea te roa mō tēnei tiēre kia wehea katoatia mai i te retina. Ki te tīmata koe ki te kite i ngā ira pēnei mō te wā tuatahi, he mea tino nui kia kite koe i tētahi tākuta kanohi.

He aha ngā wāhanga o te PVD?

Kāore tēnei āhuatanga e kiia nei ko te ``(PVD)`` e puta katoa i te wā kotahi. Ka heke haere te kiriuhi i roto i ētahi wāhanga. He tukanga taiao tēnei e puta ana i te pakeketanga.

E whā ngā wāhanga matua:

• Wāhanga 1: Ka tīmata te wetewete o te kiri i roto i tō kanohi mai i te macula (te wāhanga o te retina e āwhina ana i a tātou ki te kite mārama me te koi), koinei te wāhanga matua o te kanohi. Engari kei te piri tonu ki tētahi kōhao iti i waenganui o te macula e kiia nei ko te fovea , e whakarato ana i te tirohanga tino koi.
• Wāhanga 2:Inaianei kei te paku marere te kiriuhi mai i waenganui o te fovea, engari tera pea kei te piri tonu ki tētahi wāhi iti rawa e kiia nei ko te foveola (kei waenganui anō hoki o te fovea).
• Wāhanga 3: I tēnei wā, kua tino wehea te kiriuhi mai i te macula, engari kei te piri tonu te io whatu, e kawe ana i te māramatanga me ngā mōhiohio whakaahua mai i te kanohi ki te roro.
• Wāhanga 4: Koinei te wā ka tangohia katoatia te kiriuhi mai i te macula me te io whatu. Koinei te mea e kiia nei e mātou he PVD katoa .

Ahakoa kāore pea i te tino hira ki a koe te mōhio ki ēnei wāhanga, ka āwhina i te tākuta kia mārama ki tō āhua.

E pēhea te noa o te ingoa o tēnei āhuatanga ko te PVD?

He mea noa ake tēnei i tō whakaaro. He mate noa tēnei e pā ana ki te tini o te tangata, ā, ka puta i a rātou e pakeke haere ana. E whakaatu ana ngā tatauranga e 66 i roto i te 100 o ngā tāngata i waenga i te 66 me te 86 tau te pakeke ka pāngia e tēnei mate. Nō reira kaua e manukanuka he mate kino tēnei ka pā ki a koe anake.

He aha ngā tohu o te PVD?

E ai ki tā tātou i kōrero ai i mua ake nei, he maha ngā tohu matua o te PVD:

• Te kite i ngā mea e mānu ana i mua i ngā kanohi (`(Floaters)`): Koinei te tohu matua e kōrerohia ana e te tini o te tangata. E kī ana ētahi he rite ēnei ki ngā pepeke iti, ki ngā tukutuku pungawerewere, ki ngā huruhuru, ki te puehu rānei. I ētahi wā ka kitea he porowhita, he porowhita rānei te āhua. I ētahi wā ka karangahia ēnei e ngā tākuta he ``(Weiss rings)`` . He tino whakarihariha ēnei ina neke haere ana, kāore?
• Ngā hihi mārama : Tērā pea ka kite ohorere ētahi tāngata i ngā hihi mārama mai i te kokonga o ō rātou kanohi, pērā i te hihi mai i te kāmera. I te nuinga o te wā ka kitea ēnei i te kokonga o ō rātou kanohi. He nui ake te tūponotanga ka puta i ngā wāhi pōuri. Nā te tangohanga o te tiēre mai i te retina i a ia e wehe ana, ka puta ēnei hihi.

Ko te mea nui ko te toro atu ki tētahi tohunga kanohi tonu mēnā kei a koe ētahi o ēnei tohu, ahakoa he tohu hou, he tohu kino rānei, i ētahi wā he tohu pea ēnei mō tētahi mate kino ake.

I te nuinga o te wā, ka memeha haere ēnei tohu, ā, i muri i ētahi marama, ka taunga tō roro ki tēnei āhuatanga, ā, kāore e tino whakararuraru i a koe.

He aha ngā take o te PVD?

I a tātou e tamariki ana, pērā i te rua tekau tau te pakeke, he matotoru, he mārama te waikura kei roto i ō tātou kanohi. Ka kiia tēnei ko te wai mata.Arā. Hei whakamārama, 99% o taua mea he wai, ko te toenga he mea pēnei i te `(collagen)` me te `(hyaluronic acid)`. I a tātou e pakeke haere ana, ka piki ake te nui o te wai i roto i tēnei tiēre, ā, ka pakaru aua muka `(collagen)`, ā, ka tīmata te tiēre ki te wai. Kātahi, nā te mea kāore i te matotoru pērā, ka mimiti aunoa te tiēre, ka wehe atu i te `(retina)`. He rite tēnei ki tētahi poihau tawhito e mimiti ana ina tukuna te hau ki waho.

Ko wai kei te nui ake te mōrearea ki te whakawhanake i te PVD?

I te mea he wāhanga tūturu tēnei o te koroheketanga, he tino onge te pāngia o te hunga kei raro iho i te 40 tau te pakeke. He maha ake te kitea i muri i te 50 tau te pakeke. Ka piki ake te tūponotanga ka pāngia rātou e tēnei mate i te kaumātuatanga.

Waihoki, ki te pāngia tetahi kanohi e te PVD, he nui te tūponotanga ka pāngia anō hoki tetahi atu kanohi i roto i ngā tau kotahi, e rua rānei e whai ake nei.

Hei tāpiritanga, ko ētahi atu āhuatanga ka whakapiki ake i te mōrearea o te whakawhanake i te PVD:

• Mō te hunga he tirohanga tata (myopia) . Arā, ko te hunga ka taea te kite tata engari kāore i te tawhiti.
• Mō te hunga mate huka (`( Diabetes Mellitus)`) .
• Mō te hunga kua pāngia e ngā whara kanohi kino i mua .
• Mō te hunga kua pokanga kanohi (hei tauira, te pokanga katarata ).

Ka taea e te PVD te whakararu i te tirohanga?

He pātai tēnei e pātaihia ana e te tini tāngata. Kāore he mamae o te PVD. Waihoki, kāore te PVD anake e mate ai te tirohanga.

Heoi, i ētahi wā, ina tangohia te kiriuhi mai i te retina, ka kaha rawa te kume , ā, ka puta he raruraru . Koinei te wā ka pāngia ai te tirohanga.

He waimarie, ka puta ēnei raruraru i roto i te iti iho i te 15 i roto i te 100 tāngata whai PVD. Ko te tikanga he maha ngā tāngata e pāngia ana e te PVD, kāore he raruraru, ā, ka memeha haere ngā tohu i roto i te wā.

Ko ngā raruraru matua ka puta ko:

• Te haehae o te retina : Ina tangohia te tiēre, ka totoro te retina, ka pakaru hoki.
• Te wetewete o te retina : He haehae i roto i te retina, e tuku ana i te wai kia turuturu mā roto i te haehae, ā, ka taea e te retina te wehe katoa mai i te kiko kei raro. He āhuatanga ohorere tēnei, ā, me tere tonu te rongoā.
• Pūngao kanohi : E ai ki tā mātou i kōrero ai, ka taea e te pūngao kanohi, te wāhanga koi rawa o te tirohanga, te whakawhanake i tētahi pūngao ki roto.
• Te pūkohu o te makula (te kiriuhi epiretinal rānei) : Ka puta he kiriuhi angiangi ki runga i te makula, ka whakaiti, ka whakapōturi hoki te tirohanga.

Koia mātou e kī atu nei kia toro atu koe ki te tākuta ina tīmata koe ki te pāngia e ngā tohu o te PVD. Kātahi ka taea e mātou te tirotiro i ngā raruraru pēnei.

Me pēhea te tātaritanga a te tākuta i te PVD?

Mena kei a koe ngā tohu o te PVD, me toro atu koe ki tētahi tohunga kanohi (tākuta kanohi, tākuta kanohi rānei) i taua wā tonu . Māna e tirotiro marie ō kanohi.

Ko te whakamātautau matua he tirotiro kanohi whānui . I roto i tēnei whakamātautau, ka tāpirihia e te tākuta ētahi pata ki roto i tō kanohi, ka whakawhānui i te karu. Mā tēnei ka taea e ia te kite i te retina, te io whatu, me te kiriuhi vitreous i roto i tō kanohi . Ka whakamahia e ia he mārama motuhake me ngā karāhe hei mahi i tēnei. Kāore tēnei whakamātautau i te tino mamae, engari tera pea ka rongo koe i te ngau iti i muri i te paninga o ngā pata, ā, tera pea ka pōuriuri tō tirohanga mō ētahi haora.

He tino onge, pērā i te wā he iti noa te toto i roto i te kanohi, ā, ki te kore e taea e te tākuta te kite tika i roto i te kanohi, ka taea e rātou te mahi i tētahi tirotiro oro-kanohi . Kāore hoki he mamae. Ka whakamahia ngā ngaru oro auau teitei hei titiro ki roto i te kanohi.

He aha ngā maimoatanga mō te PVD?

He raruraru anō hoki tēnei e pāngia ana e te tini tāngata. Mēnā kāore he raruraru, kāore e hiahiatia he maimoatanga motuhake mō te PVD. Nā te mea he mea tupu noa iho.

Heoi, hei karo i ngā raruraru mai i te PVD, he pai ake te tirotiro i ō kanohi ina tīmata te pāngia e ngā tohu, ā, ki te taunaki tō tākuta, me tirotiro anō i roto i te whā ki te ono wiki. Ka kiia tēnei he tirotiro whai muri .

I tēnei whakamātautau tuarua, ka tirohia e te tākuta ētahi mea. Ko tētahi he tirotiro mēnā i ngaro tetahi mea i te wā i kitea ai te mate PVD i te tuatahi. Ko te tuarua he tirotiro mēnā kua puta he raruraru hou. Hei tauira, kāore pea i kitea he pakaru o te retina i te wā o te whakamātautau tuatahi, engari ka puta pea i muri mai. Mēnā he pakaru, ka taea te rongoā wawe.

Kāore i te tino maha ngā mahi pokanga mō ngā kanohi e mānu ana, nā te mea he tūponotanga kei roto (hei tauira, te mate, te katarata, te wehenga o te retina). Heoi, mō ētahi tāngata, mēnā he tino whakararuraru ngā kanohi e mānu ana, ā, kāore e taea e rātou te mahi i ia rā, ka taea te mahi i tētahi tikanga e kiia nei ko te vitrectomy hei tango i te kiriuhi. Heoi, he pai ake te kōrero ki tētahi taote pokanga vitreoretinal , he taote pokanga e tohunga ana ki te retina me te karu kanohi, i mua i te mahi pera.

Kāore he huarahi hei ārai i te whanaketanga o te PVD?

Engari, kāore he huarahi hei ārai i te PVD. He wāhanga tūturu tēnei o te koroheketanga, pērā i te hina o ō tātou makawe, te kita rānei o ō tātou kiri.

Engari, ko te mea tino nui ka taea e koe te mahi, ki te kite koe i ētahi huringa hou i roto i tō tirohanga,(Hei tauira: Te kitenga ohorere i te maha o ngā mea e mānu ana, te kitenga i te nui o te māramatanga, te ahua kei te kapi tetahi wāhanga o tō tirohanga i te mata pango) He mea nui kia whakamōhio tonu atu ki te tākuta kanohi. Mā tēnei ka āwhina ki te whakatau mēnā he mate kanohi kē atu, ā, mēnā kua puta he raruraru, ka taea te tīmata wawe i te maimoatanga.

He aha te heke mai mō te tangata whai PVD?

Ka taea e te hunga whai PVD te mahi i ā rātou mahi noa me te kore he raruraru. Kāore he raruraru ki ngā mea pēnei i te taraiwa, te pānui pukapuka, te mahi rānei i runga i te rorohiko.

Ahakoa kāore tēnei āhuatanga e memeha haere, ka memeha haere pea ngā mea e mānu ana me ngā mea e kanapa ana i roto i te wā, ā, ka kore e kitea. Nā te mea ka taunga haere tō roro ki ngā mea e mānu ana, ā, ka ako ki te kore e aro ki aua mea.

He tino tūponotanga ka puta te PVD i te kanohi kē i roto i te tau, i ngā tau e rua rānei i muri i te tīmatanga o te PVD. Mēnā ka puta ngā tohu i te kanohi kē, me tirotirohia hoki taua kanohi kia kore ai he pakaru o te retina.

Kāore te nuinga o te tangata e pāngia e ngā raruraru pēnei i te pakaru o te retina. Heoi, he mea nui kia tirotirohia tō kanohi kia mōhio ai kāore he mate kino ake.

He aha tāku e taea ai te mahi hei whakaiti i te kitea o ēnei mea e mānu ana i te kāinga?

Ahakoa kāore he maimoatanga motuhake mō te PVD, ka taea e ēnei mea te āwhina ki te whakaiti i te mamae o ngā mea e rere ana me ngā uira e haere tahi mai ana me ia:

• Āta nekehia ō kanohi ki runga, ki raro, ki taha ki taha, me te porowhita haere. Tērā pea ka neke atu te mea e mānu ana i te wāhi e titiro tika ana koe.
• Whakaitihia te kanapa o ngā mata pēnei i ngā waea atamai, ngā rorohiko, me ngā pouaka whakaata. Tērā pea ka whakaitihia te kitea o ngā mea e mānu ana.
• Whakamahia tika ngā mōhiti kanohi i tohua e tō tākuta.
• Mauria ngā mōhiti kanohi i ngā wāhi e mārama ana, inā koa i te wā e haere ana koe i te rā. Tērā pea ka whakaitihia te tirohanga a ngā mea e mānu ana.

Ahakoa kāore pea ēnei e tino whakaora, tera pea ka āwhina i te whakaiti i te mamae.

He mate kino te PVD?

He ahua whakamataku pea te ingoa "Posterior Vitreous Detachment". Engari, waimarie, ehara tēnei i te mate kanohi kino anake. He tukanga taiao e puta ana i a tātou e pakeke haere ana. Neke atu i te haurua o ngā kaumātua i ngā whenua pēnei i te Hononga o Amerika ka pāngia e tēnei mate.

Ahakoa ehara tēnei āhuatanga i te mea kino, ka taea e ngā raruraru te pā mai. Mēnā ka puta he mea pēnei i te haehae o te retina, te wehenga rānei o te retina i kōrerotia e tātou, me tere tonu te rongoā, ki te kore ka ngaro tō tirohanga mō ake tonu atu.

Nō reira, ki te pāngia koe e ētahi tohu o te PVD, he mea nui kia toro atu koe ki tētahi tohunga kanohi kia kitea ai mēnā he mea nui ake, me rongoā rānei. Kaua e manukanuka, he mea ngāwari noa iho i te nuinga o te wā.

Nā, he aha ngā mea hei maumahara mā tātou i tēnei?

Āe, me whakarāpopoto tātou i ngā mea hei maumahara māu mai i ngā mea kua kōrerohia e tātou:

• Ko te (PVD) te wehenga o te waikura i roto i te kanohi mai i te retina i a tātou e pakeke haere ana. He mea tino noa tēnei, ā, kāore he mea hei manukanuka.
• Mena ka puta he mea mānu, he ira pango, he hihi mārama rānei i mua i ō kanohi, he tohu pea ēnei nō te PVD.
• Mena ka puta ohorere mai ēnei tohu, he mea hou, he mea piki haere rānei, me toro atu koe ki tētahi tākuta kanohi. Ahakoa ehara te PVD i te mea morearea, ka taea e ia te arahi ki ngā raruraru nui, pērā i te pakaru o te retina.
• I te nuinga o te wā, kāore e hiahiatia he maimoatanga motuhake mō te PVD. Heoi, he mea nui kia whai whakamātautau whai muri i ngā tohutohu a tō tākuta hei tirotiro i ngā raruraru.
• Ka memeha haere ēnei tohu i roto i te wā. Ka taunga tō roro ki ēnei tohu. Nō reira, he mea nui kia manawanui, kaua e mataku.
• Ko tāu kawenga te tiaki i ō kanohi! Rapua he tohutohu hauora i te wā tika.

Ko tāku tumanako ka kitea e koe he whai hua ēnei mōhiohio. Mēnā he pātai anō āu, kaua e wareware ki te kōrero ki tō tākuta.
