Izivivinyo eziyisithupha ze-Glaucoma

Ukuhlolwa okuphelele kweso kuhlanganisa isheke se-glaucoma. I-glaucoma yisifo seso ngokuvamile esibangelwa ukucindezeleka okuphakeme emehlweni. I-glaucoma ingabangela ukulahleka kombono, kaningi ngaphandle kwempawu zokuxwayisa noma izimpawu. Izivivinyo zamehlo njalo, kuhlanganise nokuhlola okuqondile, kubalulekile ekutholeni i-glaucoma ekuqaleni. Uma utholakala masinyane, i-glaucoma ingaphathwa kahle ukuvimbela ukulahlekelwa okukhulu kwombono. Ukulandela ukuhlolwa okuyisithupha okusetshenziselwa ukusiza ukuthola i-glaucoma.

I-Tonometry

I-Tonometry yinto ejwayelekile kakhulu ukukala ukucindezela ngaphakathi kweso, owaziwa nangokuthi ingcindezi ye-intraocular (IOP). Ukucindezeleka kwamehlo kuphakeme kunendawo evamile umuntu engozini enkulu ye- glaucoma . Kubalulekile ukuqonda ukuthi ukucindezeleka okuphakeme kunokujwayelekile akusho ukuxilongwa okucacile kwe-glaucoma. Nakuba abantu abaningi bewela ebangeni elithile elijwayelekile, kungenzeka ukuba ne-glaucoma ene-eye ephansi ye-eye futhi ingabi ne-glaucoma enezingcindezi eziphakeme. Okubaluleke nakakhulu ukuthi ngabe ingcindezi ishintsha kakhulu futhi iphinde iphinde yenzeke nokuthi yini leyo ncindezi yeso elithile eyenza iso lakho.

Ophthalmoscopy

I-ophthalmoscopy isetshenziselwa ukuhlola ngaphakathi kweso. I-ophthalmoscopy ingenziwa ngehlo elihlanjululwe noma elingenalutho. Udokotela wezilanga usebenzisa ama-lens akhethekile kanye namadivayisi wezokwelapha ukuze abuke i-nertic optic. Umbala, ukuma kanye nempilo yonke ye-optic nerve kubalulekile ekuhloleni kwe-glaucoma. Udokotela angase futhi asebenzise ikhamera yedijithali ukuze athole isisindo se-optic. Ngezinye izikhathi, izithombe ezithathwe nge-stereo zithathwa ukuze zinikeze isithombe esise-3-dimensional ukuze kuhlolwe kangcono isimo somumo we-nertic optic.

I-Gonioscopy

I-Gonioscopy iyivivinyo esebenzisa idivaysi ekhethekile ebonakalayo ukuze uthinte ngobumnene buso ukuze uhlole i-angle lapho i-cornea ihlangana khona ne-iris. Kungakhathaliseki ukuthi leli hambo livuliwe noma livaliwe lingatshela udokotela ukuthi yiliphi i-glaucoma ekhona, nokuthi i-glaucoma ingaba nzima kangakanani. I-Gonioscopy nayo ingagcwaliswa ngokusebenzisa i- optical coherence tomography.

Ukuvivinya kweMidlalo Ebonakalayo

Ukuhlolwa kwendawo okubonakalayo, eyaziwa nangokuthi i-perimetry, kuyisivivinyo esilinganisa ukuthi ubukeka kanjani umbono womuntu. Ngesikhathi sokuhlolwa kwensimu ebonakalayo, uzobukeka ngokuqondile ekukhanyeni okuncane noma okunye okuhlosiwe futhi uzocelwa ukuba umhloli awazi lapho ubona ukukhanya okukhanyayo kuvulekile ohlangothini lombono wakho wendawo. Iningi lokuhlolwa kwensimu elibukwayo namhlanje liyikhompyutha. Ukuhlolwa kwamasimu okubonakalayo kudinga ukuphindaphindiwe izikhathi eziningana ngaphambi kokuba udokotela enze ukuhlolwa okuvumelekile.

Ukuhlaziywa kweNiber Fiber

Ukuhlaziywa kwe-fibre ye-nerve yindlela entsha yokuhlolwa kwe-glaucoma lapho ukulingana kwe-fibre nerve fibre kulinganiswa khona. Izindawo zokuhlala zingabonisa ukulimala okubangelwa i-glaucoma. Lokhu kuhlolwa kuhle kakhulu ezigulini ezingase zibhekwe njengomsolwa we-glaucoma futhi futhi zibonise ukuthi i-glaucoma yomuntu iyaqhubeka iba yimbi yini.

I-Pachymetry

I-pachymetry yindlela yokulinganisa ubukhulu be-cornea. Nakuba ucwaningo lusacubungulwa ngokubaluleka kwe-corneal thickness, i-pachymetry iqala ukudlala indima enkulu ekuhlolweni kwe-glaucoma. Ukuqina kwe-cornea kubonakala kuthonya ukucindezeleka kwamehlo uma i-tonometry yenziwa.
