Funso: Kodi GDx ndi chiyani?
Dokotala wanga wandiitanitsa mayeso a GDx. Zimatanthauza chiyani? Kodi nkofunikira?
Yankho:
Dokotala wanu wapereka mayeso otchedwa "GDxTM Nerve Fiber Analyzer" (GDx). Mayeso a GDx ndi mayesero atsopano omwe atsimikiziridwa kuti ndi othandiza pakupeza ndi kuyang'anira glaucoma . GDx ndi chida chomwe chimagwiritsa ntchito laser kuti chidziwitse kukula kwa mitsempha ya mitsempha.
Mayesero akale a glaucoma ayamba kuzungulira kuyeza kwa diso kapena kuyerekezera kuti glaucoma ili ndi gawo lanu lonse. Ngakhale mayesowa ndi ofunika kwambiri pa chithandizo ndi kasamalidwe ka glaucoma, zingakhale zothandiza kuyesa kapena kuyesa mofulumira chomwe chiwonongeko cha glaucoma chingayambitse mitsempha ya m'mitsempha kumbuyo kwa diso.
Mitsempha ya mitsempha ya mitsempha imakhala ndi mamiliyoni amtundu wina wotchedwa "axons" umene uli pafupi ndi mitsempha ya optic ndi kufalikira pa retina yako. Kwa odwala ambiri omwe ali ndi glaucoma, kuwonongeka kwa mitsempha ya mitsempha yambiri kungakhale kochitika kale ndi nthawi yomwe masomphenya onse atayika. Glaucoma imayambitsa matenda omwe amachititsa kuti mitsempha ya optic iwonongeke. Mitsempha ya optic imapangitsa kunyamula zithunzi ku ubongo. Glaucoma amadziwika ngati "wodzaza maso," chifukwa anthu ambiri sakudziwa kuti ali ndi vuto mpaka masomphenya aakulu atayika.
GDx imagwiritsa ntchito mtundu wopanga laser polarimeter kuti ayese kuchuluka kwake kwa mitsempha ya mitsempha. Njirayi ndi yopweteka ndipo nthawi zambiri imachitika pa wophunzira wosaphunzira. Kutalika kwa mitsempha ya mitsempha yazitsulo ndiyeno kufanizidwa ndi mitsempha ya mitsempha ya maso. GDx imapanga makina a mitsempha ndipo amawafanizira ndi adiresi ya odwala abwino, omwe alibe glaucoma.
Kupukuta kwa ulusi kumasonyeza glaucoma. DZIWANI ZOTHANDIZA ZOKHUDZA IFEYO LOWANI / WEBUSAITI YOVOMEREZEKA YA MBONI ZA YEHOVA WERENGANI Baibulo Nsanja ya Olonda Galamukani! Zina ... NKHANI ZOTHANDIZA
Mayeso a GDx ndi amphamvu kwambiri pakuzindikira koyambirira pamene maphunziro asonyeza kuti anthu oposa 50% omwe ali ndi glaucoma sakudziwa kuti ali nawo. Zimathandizanso kuti muyambe kugwiritsira ntchito glaucoma pazaka, chifukwa zimatengera kusintha kwakukulu poyerekeza ndi deta yam'mbuyo ya GDx. Kudziwa izi kumathandiza dokotala wanu kuti athe kusankha ngati muli ndi glaucoma kapena ayenera kuonedwa kuti ndi "suspect glaucoma." Ngakhale kusanthula kwa mitsempha ya mitsempha ngati kuyesa kosavomerezeka sikumapangitsa kuti munthu adziwe bwinobwino glaucoma, imapereka dokotala wanu deta yomwe idzawonjezera pa vuto lanu lonse kuti pakhale zisankho zabwino zokhudza mankhwala anu.
Ngakhale GDx akadali kuyesa bwino, ikukhala chida chosakhalitsa. Kupititsa patsogolo kwa GDx ndi zida zina zimapangitsa kuti apange oCT: Optical Coherence Tomography .
Kodi OCT ndi chiyani?
Kugwirizana molumikiza tomography (OCT) ndi teknoloji yosaganizira zojambulazo zomwe zimagwiritsidwa ntchito kuti zipeze zithunzi zapamwamba za retina .
OCT ndi ofanana ndi kuyesa kwa ultrasound, kupatula kuti kujambula kumachitika poyerekeza kuwala osati kumveka. OCT imapanga makina a retinal nerve fiber ku glaucoma ndi matenda ena a mitsempha ya optic.
Kuphunzira zambiri za OCT
Kugwirizana Mogwirizana Tomography, yomwe imatchedwanso OCT, ndiyo njira ya optometrists ndi ophthalmologists kufotokoza kumbuyo kwa diso kuphatikizapo macula, mitsempha ya optic, retina ndi choroid.
Pakati pa kafukufuku wa diso, optometrists ndi ophthalmologist angayang'ane kumbuyo kwa diso ndi matupi ake. Komabe, nthawizina madokotala amafunikira mwatsatanetsatane kapena amafunika kufufuza mwatsatanetsatane pansipa zomwe ziri zovuta kuziwona ndi njira zoyenera.
Mu njira zina, zikhoza kuyerekezedwa ndi "MRI ya retina." Ena amafotokoza kuti ndiwotchi yotchedwa ultrasound chifukwa zithunzi zimayang'ana pakati pa mapepala kuti apereke madokotala ndi zithunzi zosiyana siyana.Zotsatanetsatane zomwe zikhoza kuwonetsedwa ndi OCT ndizolingalira kwambiri kuti madokotala akuwona zinthu zomwe sichinaonekepo kale mu diso la umunthu wamoyo .
