Qhov sib txawv tseem ceeb ntawm sab hauv thiab sab nraud ophthalmoplegia yog qhov ophthalmoplegia sab hauv yog vim kev puas tsuaj rau qhov nruab nrab longitudinal fasciculus whereas sab nraud ophthalmoplegia feem ntau yog ob qho kev puas tsuaj rau qhov nruab nrab longitudinal fasciculus. Yog li ntawd, qhov sib txawv ntawm lub hauv paus pathological ntawm tus kab mob ua rau muaj qhov sib txawv tseem ceeb ntawm sab hauv thiab sab nraud ophthalmoplegia.

Internal Ophthalmoplegia yog dab tsi?
Internal ophthalmoplegia yog vim kev puas tsuaj rau qhov nruab nrab longitudinal fasciculus. Yog hais tias qhov txhab nyob rau sab xis ntawm lub fasciculus, lub qhov muag sab xis yuav tsis muaj peev xwm mus ntxiv thaum lub sij hawm sim lateral ntsia, thiab sab laug qhov muag yuav tsim nystagmus. Thaum cov kev tshwm sim no tshwm sim ob sab uas feem ntau yuav yog vim muaj ntau yam sclerosis.
Sab Nrauv Ophthalmoplegia yog dab tsi?
Tsev tuag tes tuag taw 3rd, 4th thiab 6th rwg qab haus huv ntawm optical apex los yog nyob rau hauv lub cavernous sinus impairs lub zog ntawm lub qhov muag. Qhov no yog hu ua ophthalmoplegia sab nraud. Tsis tas li ntawd, yog tias qhov mob nyob rau theem ntawm qhov kho qhov muag apex, nws muaj feem ntau yuav yog metastatic tso nyiaj uas cuam tshuam rau cov hlab ntsha dhau ib sab.
Ntawm qhov tod tes, yog tias kev puas tsuaj rau cov hlab ntsha nyob rau hauv lub qhov ntswg qhov ntswg, nws feem ntau yog thib ob rau cavernous sinus thrombosis lossis meningioma.
Qhov txawv ntawm Sab Hauv thiab Sab Nraud Ophthalmplegia yog dab tsi?
Sab nraud ophthalmoplegia yog tus tuag tes tuag taw ntawm 3rd, 4th thiab 6th cranial qab haus huv ntawm lub qhov muag apex lossis hauv lub qhov ntswg qhov ntswg uas ua rau lub qhov muag tsis pom kev. Internal ophthalmoplegia, ntawm qhov tod tes, yog vim kev puas tsuaj rau qhov nruab nrab longitudinal fasciculus qhov twg tus neeg mob tsim nystagmus ntawm lub qhov muag contralateral thaum sim lateral ntsia mus rau sab nraud ntawm qhov txhab. Nyob rau hauv sab nraud ophthalmoplegia, qhov kev puas tsuaj yog nyob rau theem ntawm lub qhov muag apex los yog nyob rau hauv lub cavernous sinus. Txawm li cas los xij, hauv ophthalmoplegia, nws yog qhov nruab nrab longitudinal fasciculus uas puas lawm.
Tsis tas li ntawd, saib ntawm qhov ua rau sab, cavernous sinus thrombosis, metastatic deposits ntawm qib ntawm optical apex thiab meningiomas yog lub ntsiab ua rau sab nraud ophthalmoplegia. Nyob rau hauv sib piv, ntau yam sclerosis yog lub ntsiab ua rau sab hauv ophthalmoplegia. Nyob rau hauv cov xwm txheej no, lub qhov muag contralateral qhia nystagmus, thiab lub qhov muag Ipsilateral pom nyuaj rau adduct thaum lub sij hawm sim lateral ntsia mus rau sab nraud ntawm qhov txhab.
