Izilingo ezithandathu zeGlaucoma

Uvavanyo olujongene neliso lubandakanya isheke se-glaucoma. I-Glaucoma yiso isifo esisoloko sibangelwa ukunyanzeliswa okuphezulu kwiso. I-Glaucoma ingabangela ukulahleka kombono, kaninzi ngaphandle kwempawu okanye izibonakalisi. Ukuhlolwa rhoqo kwamehlo, kuquka iimvavanyo ezithile zokuxilonga, kubalulekile ukufumanisa okokuqala i-glaucoma. Ukuba ufunyanwe ngokukhawuleza, i-glaucoma ilawulwa ngokufanelekileyo ukukhusela ukulahleka kwemibono. Ukulandela kukho iimvavanyo ezintandathu ezisetyenziselwa ukufumana i-glaucoma.

Tonometry

I-Tonometry yinto eqhelekileyo yokuvavanya ukulinganisa ingcinezelo ngaphakathi kwiso, eyaziwa nangokuxinzelelo lwe-intraocular (IOP). Ukuba noxinzelelo lwamehlo luphakamileyo kuneendawo eziqhelekileyo umntu ubeka umngcipheko ophezulu kwi- glaucoma . Kubalulekile ukuqonda ukuba unengcinezelo ephakamileyo kunezinye eziqhelekileyo ayithethi ukuxilongwa ngokucacileyo kwe-glaucoma. Nangona uninzi lwabantu luwela kwinqanaba elithile eliqhelekileyo, kunokwenzeka ukuba ube ne glaucoma enexinzelelo elisezantsi kwaye ungabi ne-glaucoma eneempembelelo eziphezulu. Yintoni ebaluleke ngakumbi ukuba ingcinezelo iyashintsha kwaye iphantsi kakhulu kunye nokuba yintoni ingcinezelo yamehlo eyenzayo kwiso lakho.

Ophthalmoscopy

I-Ophthalmoscopy isetyenziselwa ukuhlola ngaphakathi kweso. I-Ophthalmoscopy inokwenziwa kwiso isohlanjululwe okanye elingaxilwanga. Ugqirha weliso lisebenzisa iilensi ezizodwa kunye nezixhobo zonyango ukuze zijonge iimbono ze-optic. Umbala, ukuma kunye nempilo yonke ye-optic nerve ibalulekile ekuhloleni kwe-glaucoma. Ugqirha unokusebenzisa kwakhona ikhamera yedijithali ukufotoza imbilini ye-optic. Ngamanye amaxesha, iifoto ze stereo zithathwa ukuze zinike umfanekiso o-3-dimensional ukuze uhlolisise kakuhle isimo esiphezulu se-nertic optic.

Gonioscopy

I-Gonioscopy ngumvavanyo osebenzisa isicatshulwa esikhethekileyo sokubamba ngenyameko ubuso belihlo ukuhlola i-angle apho i-cornea ihlangabezana ne-iris. Ingaba le ngqungquthela ivulekile okanye ivalwe ingaxelela ugqirha ukuba yiyiphi i-glaucoma ekhoyo, kwaye i-glaucoma ingaba nzima kangakanani. I-Gonioscopy ingagqitywa nokusebenzisa i- optical coherence tomography.

Ukuvavanywa kweeMpawu zoLwazi

Ukuhlolwa kwintsimi ebonakalayo, eyaziwa ngokuba yi-perimetry, luvavanyo olulinganisa indlela umntu angabonwa ngayo. Ngexesha lokuvavanywa kwintsimi ebonakalayo, uya kujonga phambili ekukhanyeni okuncinane okanye kwelinye ijolise kwaye uya kucelwa ukuba umhloli awazi xa ubona ukukhanya okukhanyayo kuvela kwicala kumbono wakho wendlela. Uninzi lwangoku vavanywa kwimihlaba namhlanje lukhomputha. Ukuhlolwa kwintsimi ebonakalayo kudla ngokuphindaphindiweyo kufuneka kuphindwe kabili ngaphambi kokuba ugqirha angenza uvavanyo oluvumelekileyo.

Uhlalutyo lweMigudu yeFiber

Uhlalutyo lwefayibha yindlela yamatye yindlela entsha yokuhlola i-glaucoma apho ububanzi bomgca we-fibre nerve bubalwa. Iindawo zokuhlala zingabonakalisa umonakalo obangelwa yi-glaucoma. Olu vavanyo luncedo kakhulu kwizigulana ezinokuthi zithathwa njengogqirha we-glaucoma kunye nokubonisa ukuba i-glaucoma yomntu iyaqhubeka ihamba phambili.

Pachymetry

I-Pachymetry yindlela yokulinganisa ubukhulu be-cornea. Nangona uphando luqhutyelwa ngokubaluleka kwe-corneal thickness, i-pachymetry iqalisa ukudlala indima enkulu ekuhlolweni kwe-glaucoma. Ubunzima be-cornea kubonakala buchaphazela ukufundwa kwesohlo xa i-tonometry isenziwa.
