Amaurosis fugax

Amaurosis fugax ke tahlehelo ea nakoana ea pono ho le leng kapa a mabeli ka lebaka la khaello ea phallo ea mali ho retina. Retina ke lisele tse sa utloisiseng khanya ka morao ho leihlo la leihlo.

Amaurosis fugax ha se lefu ka bolona. Sebakeng seo, ke sesupo sa mathata a mang. Amaurosis fugax e ka hlaha ka mabaka a fapaneng. Lebaka le leng ke ha lesela la mali kapa sekotoana sa lejoe le koala mothapo ka leihlong. Lero la mali kapa lejoe hangata le tloha mothapong o moholoanyane, joalo ka mothapo oa carotid molaleng kapa mothapong o ka pelong, ho ea mothapong o ka leihlong.

Plaque ke ntho e thata e bonoang ha mafura, k'holeseterole le lintho tse ling li haella maboteng a methapo. Mabaka a kotsi a kenyelletsa:

• Lefu la pelo, haholo-holo ho otla ha pelo ka tsela e sa tloaelehang
• Ho sebelisa joala hampe
• Tšebeliso ea Cocaine
• Lefu la tsoekere
• Nalane ea lelapa ea stroke
• Khatello ea mali e phahameng
• Cholesterol e phahameng
• Ho eketsa lilemo
• Ho tsuba (batho ba tsubang pakete e le 'ngoe ka letsatsi ba ipeha kotsing ea ho tšoaroa ke stroke habeli)

Amaurosis fugax e ka hlaha hape ka lebaka la mathata a mang a joalo ka:

• Mathata a mang a mahlo, a kang ho ruruha ha methapo ea optic (optic neuritis)
• Lefu la methapo ea mali le bitsoang polyarteritis nodosa
• Ho tšoaroa ke hlooho ea migraine
• Hlahala ea boko
• Kotsi ea hlooho
• Multiple sclerosis (MS), ho ruruha ha methapo ka lebaka la lisele tsa 'mele tsa' mele tse hlaselang tsamaiso ea methapo
• Systemic lupus erythematosus, lefu le itšireletsang mafung leo lisele tsa 'mele tsa' mele li hlaselang lisele tse phetseng hantle 'meleng oohle

Matšoao a kenyelletsa tahlehelo ea tšohanyetso ea pono ho le leng kapa a mabeli mahlo. Hangata hona ho nka metsotsoana e seng mekae ho isa ho metsotso e mengata. Kamora moo, pono e khutlela setloaeling. Batho ba bang ba hlalosa tahlehelo ea pono joalo ka moriti o moputsoa kapa o motšo o theohelang leihlo.

Mofani oa tlhokomelo ea bophelo o tla etsa tlhahlobo e felletseng ea leihlo le tsamaiso ea methapo. Maemong a mang, tlhahlobo ea mahlo e tla senola sebaka se khanyang moo lehloa le thibang methapo ea kutlo.

Liteko tse ka etsoang li kenyelletsa:

• Ultrasound kapa magnetic resonance angiography scan ea mothapo oa carotid ho lekola liphahlo tsa mali kapa lejoe
• Liteko tsa mali ho lekola cholesterol le tsoekere maling
• Liteko tsa pelo, joalo ka ECG ho lekola ts'ebetso ea eona ea motlakase

Kalafo ea amaurosis fugax e ipapisitse le sesosa sa eona. Ha amaurosis fugax e bakoa ke leqhubu la mali kapa lejoe, ho tšoenyeha ke ho thibela stroke. Lintlha tse latelang li ka thusa ho thibela stroke:

• Qoba lijo tse mafura 'me u latele phepo e nepahetseng, e se nang mafura. U SE KE ua noa lino tse tahang tse fetang 1 ho isa ho tse 2 ka letsatsi.
• Ikoetlise khafetsa: metsotso e 30 ka letsatsi haeba u sa nona; Metsotso e 60 ho isa ho e 90 ka letsatsi haeba o nonne haholo.
• Khaotsa ho tsuba.
• Batho ba bangata ba lokela ho ikemisetsa khatello ea mali e ka tlase ho 120 ho isa ho 130/80 mm Hg. Haeba u na le lefu la tsoekere kapa u bile le stroke, ngaka ea hau e kanna ea u joetsa hore u ikemisetse khatello e tlase ea mali.
• Haeba u na le lefu la tsoekere, lefu la pelo, kapa ho thatafala ha methapo, cholesterol ea hau ea LDL (e mpe) e lokela ho ba tlase ho 70 mg / dL.
• Latela merero ea hau ea kalafo ea ngaka haeba u na le khatello e phahameng ea mali, lefu la tsoekere, k'holeseterole e phahameng kapa lefu la pelo.

Ngaka ea hau e ka boela ea khothaletsa:

• Ha ho kalafo. U kanna ua hloka ho eteloa khafetsa ho lekola bophelo ba pelo ea hau le methapo ea carotid.
• Aspirin, warfarin (Coumadin), kapa lithethefatsi tse ling tse fokotsang mali ho theola menyetla ea hore u tšoaroe ke stroke.

Haeba karolo e kholo ea methapo ea carotid e bonahala e koetsoe, ho etsoa opereishene ea carotid endarterectomy ho tlosa ho thiba. Qeto ea ho etsa opereishene e boetse e ipapisitse le bophelo ba hau ka kakaretso.

Amaurosis fugax e eketsa menyetla ea ho tšoaroa ke stroke.

Bitsa mofani oa hau haeba ho na le tahlehelo ea pono e hlahang. Haeba matšoao a nka nako e teletsana ho feta metsotso e seng mekae kapa haeba ho na le matšoao a mang ka tahlehelo ea pono, batla ngaka hang-hang.

Ho foufala ha monocular ha nakoana; Ho lahleheloa ke pono ha nakoana ka monocular; TMVL; Ho lahleheloa ke pono ha nakoana ka monocular; Ho lahleheloa ke pono ea sebono ka nakoana; TBVL; Ho lahleheloa ke pono ea nakoana - amaurosis fugax
