PERRLA ndi Mayeso Anu

Chidule cha kuyesedwa kwa mayeso a pupillary

Kodi mumadabwa kuti dokotala wanu akuyang'ana chiyani pamene akuwala? Dziwani kuti kuwala kumeneku sikungakwiyitseni-kuli ndi cholinga ndipo "kungakuthandizeni" momwe dongosolo lanu lamanjenje likugwirira ntchito.

Kwenikweni, mayeso a diso, otchedwa pupillary response test, amagwiritsidwa ntchito kufufuza momwe magulu a mitsempha yachiwiri (yotchedwa mitsempha ya optic) imagwira ntchito (ndi mitsempha ya oculomotor). Mitsempha ya optic imatulutsa zizindikiro kuchokera ku retina kupita ku ubongo. Kuwonongeka kwa mitsempha ya optic (monga optic neuritis ) kungayambitse mavuto masomphenya.

Mitsempha ya oculomotor imayendetsa mitsempha inayi ya asanu ndi imodzi komanso imayang'anitsanso kugwedeza kwa mwanayo komanso mphamvu ya diso. Kuwonongeka kwa mitsempha ya oculomotor (monga kuvulazidwa kwa mutu, matenda, kuthamanga kwa magazi, kapena kupweteka kwa ubongo) kungayambitse masomphenya awiri kapena wophunzira kapena wopsepuka.

Kodi PERRLA ndi chiyani?

Pamene dokotala kapena namwino akuyang'ana maso a wodwalayo, PERRLA ndi mawu omwe amamasuliridwa kuti afotokoze maonekedwe ndi maso a maso. Chimaimira:

• P mapiritsi
• E qual
• R ound
• Yayikirapo
• L ight ndi
• Malo okhala (zomwe zikutanthauza mphamvu ya maso kuganizira pa zinthu zomwe ziri pafupi ndi kutali)

Kuyesedwa kwa diso (kofotokozedwa ndi PERRLA) kungakhale kosazolowereka ngati ophunzira ali:

• Osati ofanana kukula
• Osati kuzungulira (misshapen)
• Musasinthe (osati kuchitapo kanthu) pamene kuwala kumawala pa iwo (ayenera kukhala ochepa)
• Musasinthe (osati kumakhala) pamene mukuyang'ana chinachake pafupi kapena kutali

Pupillary Response Test Tested by PERRLA

Pofuna kuyesa pupillary yankho la funso , munthu amafunsidwa kuti akhale pansi kapena malo ochepa kuti achite izi:

• Dokotala kapena namwino adzayang'ana kufanana pakati pa ophunzira onse ndi kuzindikira mawonekedwe ndi kukula asanayambe kuyesedwa.
• Chingwe chaching'ono chogwiritsira ntchito pamanja chimasunthira mkati ndi maso pakati pa maso a masekondi awiri ndi kugwiritsira ntchito kuwala. Kuwunika kumeneku kumatchedwa "kuyesa kuwala kwawunikira." Dokotala kapena namwino akuyang'ana mwachindunji kuyesayesa kwawotchi, kuti awone ngati ophunzira akucheperapo (poyikira) poyankha kuwala, mosasamala kanthu komwe diso likuwunikira.
• Pa nthawi yomweyi, kuvomereza kwa wophunzira wina kuyenera kuchitika (izi zimatchedwa yankho lachidziwitso ).
• Dokotala kapena namwino angagwiritse ntchito cholembera kapena chala chachindunji kuti awone momwe maso akukonzekera pa chinthu. Chingwe chimachotsedwa, kutsogolo ndi mbali kumbali kuti muwone ngati maso angathe kuganizira. Kawirikawiri, ophunzira amapitiriza pamene akukonzekera pa chinthu chomwe chikusuntha pafupi kapena kutali.

Zomwe PERRLAYESI Yavumbulutsira Zimatsimikizira

Kuchepetsa kulapa kwachindunji ku kuwala m'diso limodzi kungakhale chizindikiro cha wachibale wotsutsana pupillary kachilombo (RAPD) . Izi zimatchedwanso Marcus Gunn wophunzira.

Pali zinthu zambiri zomwe zimayambitsa RAPD monga:

• Glaucoma yolimba
• Optic neuritis
• Chotupa cha mitsempha yamagetsi
• Ischemic optic neuropathy (imatchedwanso "kupweteka kwa mitsempha ya optic")
• Kuvulala pamutu komwe kumawononga mitsempha ya optic
• Kuwonongeka kwa opaleshoni kwa mitsempha ya optic (chifukwa cha kuwonongeka kwa matenda a anesthesia, diso, orbital, sinus, kapena opaleshoni ya pulasitiki )
• Matenda amphamvu a retina

Malo osasangalatsa a malo ogona (kuyankha poyang'anitsitsa chinthu choyang'ana kumaso) angayambidwe ndi zinthu zosiyanasiyana, kuphatikizapo:

• Zilonda za mitsempha ya optic
• Zilonda za mitsempha ya oculomotor

Mawu Ochokera

Diso ndi chiwalo chovuta kwambiri monga mitsempha yomwe imayendetsa iyo. Komabe, zodabwitsa, mayesero ophweka ngati a pupillary reaction test ali ngati mawindo m'kati mwanu.

Ngakhale kuyesedwa kosayembekezereka sikungapereke ndondomeko yeniyeni yeniyeni, imasonyeza dokotala kuti chinachake sichiri choyenera komanso kuti kuchipatala kwakukulu kofunika kwambiri.

Monga nthawizonse, onetsetsani kuti mufunse dokotala wanu za zizindikiro zanu ndi zotsatira za mayeso aliwonse okhudza diso lanu ndi masomphenya.
