Oftalmonevrologicheskih manifestation ntawm cov tsos mob yog cov thawj Atrophy ntawm lub optic qab haus huv, kev hloov hauv lub teb ntawm view. Lawv siv nyob rau hauv lub suprasellar adenoma txoj kev loj hlob (microadenomas). Lub siab ntawm cov qog nyob rau cheeb tsam ntawm Sella diaphragm ua rau ib tug mob taub hau uas yog laus nyob rau hauv lub sab nqaij daim tawv, frontal thiab pozadiglaznichnoy cheeb tsam. Raws li ib tug txoj cai, nws yog tsis nrog xeev siab thiab tsis yog nyob rau lub cev txoj hauj lwm. Nws tsis yog ib txwm tau mus tshem tawm cov tshuaj. Ua raws li los ntawm cov pob loj hlob ua rau defeat hypothalamic lug. Pob txoj kev loj hlob nyob rau hauv cov kev taw qhia ntawm cov hauv qab thaj tsam ntawm lub Sella turcica, thiab kis tau nws nyob rau hauv lub qhov ntswg yuav manifest nov ntawm nqaij tawv ntawm qhov ntswg congestion thiab cais therefrom lub CSF (hlwb txha nqaj qaum kua).

Tus ntse nce nyob rau hauv kev mob thiab oftalmonevrologicheskih cov tsos mob feem ntau yog txuam nrog ntau zog intensities ntawm lub qog txoj kev loj hlob (e.g., cev xeeb tub), los yog los ntshav mus rau hauv lub qog.

Rau refractory operative txoj kev siv tshuaj hlav. Raws li ib tug txoj cai, siv microsurgery. Tumor ntawm cov loj loj yauv neurosurgery. Tom qab muab hlais tawm lawm, tawg txoj kev kho yog tsa.

Rau hormonally tsaug zog adenomas siv phais thiab tawg txoj kev kho.
