Kukhala ndi mphamvu yapamwamba kuposa yeniyeni ya diso kapena kuyeza kwa mphamvu yamadzi mkati mwa diso kumapangitsa munthu amene ali pachiopsezo chotenga glaucoma . Anthu ena akhoza kukhala ndi mayesero aakulu, osakhala ndi glaucoma ndipo anthu ena amatha kukhala ndi vuto loyang'ana m'maso, motsogoleredwa ndi glaucoma. Komabe, pafupipafupi, kukwera kwa diso, ndikoopsa kwambiri kuti mukhale ndi glaucoma.
Panopa akukhulupirira kuti kutulutsa makulidwe kumathandiza kwambiri potanthauzira moyenera kuthamanga kwa diso. Choncho kuyenerera kwa cornea , kuyenera kuganiziridwa pamene mukuganiza kuti mungayambe kukhala ndi glaucoma.
Panthawi ina, ankaganiza kuti odwala onse amafanana ndi odwala onse. Kafukufuku wam'tsogolo, komabe, akusonyeza kuti kukula kwa nyamayi kumasiyana kwambiri kuchokera kwa munthu ndi munthu.
Kupsyinjika mkati mwa diso kumayesedwa ndi chipangizo chotchedwa " tonometer ." Kulondola kwa kuwerenga kwachisokonezo, komabe, kungakhale kusocheretsa. Kafukufuku wasonyeza kuti kachilombo kakang'ono kamene kamakhala kochepa kamene kamakhala kochepa kwambiri, komabe khungu linalake lingapangitse kuchuluka kwake. Izi sizingakhale zofunikira, chifukwa munthu yemwe akuoneka kuti ndi wotsika kwambiri (akusonyeza kuti alibe chiopsezo chotenga glaucoma) akhoza kukhala pachiopsezo chachikulu ndipo akusowa chithandizo. Diso lenileni la munthuyo limangowoneka limakhala lochepa chifukwa cha kuchepa kwa cornea.
Madokotala tsopano akuphatikizapo kuchuluka kwa makulidwe a cornea, otchedwa pachymetry, monga mbali ya kulingalira kwa glaucoma. Ngakhale kuti ochita kafukufuku sakugwirizana ndi chenichenjezo chimene chiyenera kugwiritsidwa ntchito, madokotala tsopano akudziwa momwe angaganizire ngati wodwala ali ndi cornea yochepa kwambiri kapena yakuda.
Pachymetry yakhala chiyeso chodziŵika kuti chidziwitso cha glaucoma chikupezeka.
Osati kusokoneza nkhaniyi mochulukirapo, koma kafukufuku wina akuwonetsa kuti kukula kwa nyenyezi kumakhudza kwambiri kuyang'ana kwa maso athu kuti tiyese, koma kukula kwake, pokha, kungakhale chiopsezo chodziyimira kuti pakhale glaucoma. Izi zingawoneke ngati zosokoneza. Komabe, kafukufuku akuyang'ana chiwopsezo cha glaucoma ndi makulidwe a cornea ya munthu, osati kwenikweni, momwe chisokonezocho chimakhudzira kudzipweteka kokha. Maphunzirowa adawonetsa kuti kugwa kwa microns 40 ya corneal makulidwe ndi ofanana ndi 70 peresenti yapamwamba yopanga glaucoma. Izi zikuwonetsa kuti cornea yambiri imakhala yokwanira, yokha, kuti iwononge chiopsezo chokwanira ndi kuthamanga kwa diso.
Ananenanso mwanjira ina, munthu amene amayenda 30 mm Hg ndipo ali ndi microni yamtundu wa 600 ali ndi theka la kapangidwe ka glaucoma kuposa munthu yemwe ali ndi mavuto a maso a mm 20 mm Hg ndi kukula kwa microns 500. Kuti likhale losavuta, cornea ikhoza kukhala chinthu chofunika kwambiri kuti chiganizire kuti mphamvu yeniyeni yeniyeni ndiyo.
Chinthu chimodzi chomwe tikudziwa, ndi chakuti pamtunda, chiwerengero cha corneal thickness, ndiyeso yofunikira kusonkhanitsa poyesa ngozi ya glaucoma.
