I-Eye Intraocular Pressure: Izimpawu, Izimbangela, Ukuxilongwa, Nokwelashwa

I-Eye intraocular pressure (IOP) ibhekisela ekucindezelweni okungaphakathi kweso okubangelwa ibhalansi phakathi kokukhiqizwa nokugeleza koketshezi lwangaphakathi lweso (i-aqueous humor). I-IOP evamile ibalulekile ekugcineni isimo nokusebenza kweso, kodwa i-IOP ephakeme ingaholela ezimweni ezinzima zamehlo, njenge-glaucoma. Kulesi sihloko, sizohlola izimpawu, izimbangela, ukuxilongwa, kanye nezinketho zokwelashwa ezihlobene nokucindezela okungavamile kwe-intraocular, okukusiza ukuthi uqonde ukubaluleka kokuqapha impilo yamehlo njalo.

Iyini I-Eye Intraocular Pressure?

Ukucindezela kwe-intraocular (IOP) ukucindezela koketshezi ngaphakathi kweso. Kubalulekile ukugcina inhlamvu yeso igcwele umoya nokugcina isimo seso. Iso likhiqiza uketshezi olubizwa ngokuthi i-aqueous humor, ondla i-lens ne-cornea. Lolu ketshezi lugeleza esweni futhi lukhishwe ngemigudu ku-cornea. Uma ukugeleza kwamanzi kuvinjiwe noma uma ukukhiqizwa koketshezi kukhuphuka, i-IOP ingakhuphuka, okuholela ekulimaleni okungaba khona ku-optic nerve kanye nokulahlekelwa ukubona.

Izimbangela Zokucindezela Kweso Eliphakeme Le-intraocular

Ukucindezela kwe-intraocular ephakeme kungabangelwa izimo ezihlukahlukene noma izici zokuphila, okuhlanganisa:

• I-Glaucoma: Imbangela evame kakhulu yokuphakama kwe-IOP, i-glaucoma yenzeka lapho imigudu yokukhipha amanzi esweni ivaleka, ivimbele ukuhleka okumanzi ukuthi kungaphumi kahle futhi kubangele ukunqwabelana koketshezi.
• Ukulimala Kwamehlo: Ukuhlukumezeka noma ukulimala kweso kungaholela ekwandeni kwe-IOP, noma ngokushesha ngemva kokulimala noma kamuva, ngenxa yokuvuvukala noma ezinye izinkinga.
• Ukusetshenziswa kwe-Corticosteroid: Ukusetshenziswa isikhathi eside kwe-corticosteroids (okungamaconsi esweni, amaphilisi, noma imijovo) kungabangela ukwanda kokukhiqizwa koketshezi kanye nokuncipha kokukhipha amanzi, okuholela ekukhuphukeni kwe-IOP.
• I-Genetics: Umlando womndeni we-IOP ephakeme noma i-glaucoma ungandisa ingozi yokuba nalesi simo. Izici ezizuzwe njengefa zingathonya ukwakheka kweso noma umsebenzi wohlelo lokudonsa amanzi.
• Ubudala: Njengoba abantu bekhula, ingozi yokuthola i-IOP ephakeme iyanda, ikakhulukazi ngemva kweminyaka engama-40.
• Ukucindezela Kwegazi Eliphezulu: Umfutho wegazi ophezulu noma umfutho wegazi ophakeme kungandisa ingozi yokuba ne-IOP ephakeme ngokuthinta imithambo yegazi yeso kanye nezindlela zokulawula uketshezi.
• Ezinye izimo zezokwelapha: Izimo ezifana nesifo sikashukela, i-hypothyroidism, noma ezinye izifo zesistimu zingase zikhulise amathuba okuba ne-IOP engavamile.

Izimpawu Zokucindezela Kweso Eliphakeme Le-intraocular

I-IOP ephakeme ayihlali ibangela izimpawu eziphawulekayo ezigabeni zokuqala. Abantu abaningi bangase babe ne-IOP ephezulu ngaphandle kwezimpawu eziyisixwayiso, yingakho ukuhlolwa kwamehlo okuvamile kubalulekile. Kodwa-ke, lapho kuvela izimpawu, zingabandakanya:

• Umbono Olufifi: Ukungaboni kahle kungase kwenzeke lapho i-IOP ephezulu iholela ekulimaleni kwenzwa ye-optic noma ezinye izingxenye zeso.
