Ukuhlolwa kwensimu ebonakalayo kuyindlela yokulinganisa insimu yakho yokubuka, noma ukuthi ungabona kanjani ohlangothini ngalunye ngenkathi ugxile amehlo akho endaweni ephakathi (umbono wendawo). Ukuqhuba ukuhlolwa kwensimu ebonakalayo kubizwa ngokuthi yi-perimetry.
Isilinganiso esisodwa sokusebenza kwakho okubukwayo ukufunda izincwadi eshadini elibonakalayo elibonakalayo. Lesi yisilinganiso sombono wakho ophakathi futhi yingxenye ebaluleke kakhulu embonweni wakho.
Noma kunjalo, lokho kuyodwa kuphela isilinganiso somsebenzi wakho wokubukwa. Esinye isici insimu yakho yonke ebonwayo, ngezinye izikhathi ebizwa ngokuthi umbono wesiphambano. Nakuba abantu abaningi bephutha njengendlela yokuhlolwa kombono wendawo, ukuvivinywa kwensimu ebonakalayo empeleni kuhloswe ukukala yonke indawo yombono njengoba kuhunyushwa ubuchopho ezinkimbini ezine zezinzwa. Izingxenye ezahlukene zobuchopho bakho zilawula izingxenye ezihlukene zensimu yakho ebonakalayo. Imiphumela ye-test field field ingahle ibone ukuthi odokotela baxilongwa.
Ukulinganisa Insimu Yakho Ebonakalayo
Kunezindlela ezehlukene zokuqhuba ukuhlolwa kwensimu ebonakalayo. Indlela ejwayelekile kakhulu yokukala ama-four quadrants ensimu ebonakalayo ukwenza "izinkinga zokubhekana neurologic". Lena yindlela ejwayelekile kakhulu yokuyihlola. Bobabili i-optometrists kanye ne-ophthalmologist benza inkambiso emasimini okubukwayo ngale ndlela ngesikhathi sokuhlolwa kwamehlo okuphelele.
Kuyenziwa ngokuba nodokotela noma ochwepheshe behlezi ekulweni kweso nesiguli. Iliso elilodwa limboziwe. Elinye ilanga libheke ngqo ochwepheshe bezinyosi kanye nomunye, iminwe emibili noma emine ibanjwe kuwo wonke ama-four quadrants. Isiguli asivunyelwe ukuthutha iso noma ukubheka iminwe kodwa kufanele siphendule ukuthi iminwe eminingana isigcinwe yini.
Ngemuva kokuthi wonke ama-quadrant amane ahlolwe, elinye iso lilinganiswa.
Uma ukulahlekelwa kwenkambu ebonakalayo kutholakala ngendlela yokubala ngomunwe noma uma udokotela esho izinguquko zensimu ezibukwayo, indlela ehlelekile kakhulu izosetshenziswa njenge-automated perimetry. I-perimeter ezenzakalelayo iyinsimbi yekhompyutha eyenza insimu ngezibani ezahlukene zobukhulu obuhlukahlukene nokukhanya. I-perimeter ezenzakalelayo iyakwazi ukuqhuba izinhlobo eziningana zezivivinyo zensimu ngendlela ehlelekile. Isivivinyo sombuthano senza abantu "nje nje babone" umbono futhi baqaphele ukuthi ubuhlungu isiguli singase sithole noma singabe singayitholi amaphuzu abhekwa njengesijwayelekile.
Lawa mabalazwe wokuzwela okubukwayo kubaluleke kakhulu ekuhloleni izifo zesistimu ebonakalayo. Amaphethini ahlukene okulahlekelwa okubukwayo atholakala enezifo zeso, isistimu ye-nerve central central nervous.
Izimbangela zezinto ezingavamile zokuhlolwa kwezemvelo zifaka lokhu okulandelayo:
- I-glaucoma
- Isifo sikashukela
- Ukucindezelwa Kwegazi Eliphakeme
- Multiple sclerosis
- I-nertic optic glioma
- Hyperthyroidism
- Ukucindezeleka kwe-Pituitary gland
- Izinkinga zesistimu ezisemkhatsini, njenge-tumor ecindezela enye yezingxenye ezibukwayo zobuchopho bakho
Uma sekuvele ukukhubazeka kwenkambu ebonakalayo, odokotela bavame ukuphinda bahlole izikhathi ezimbalwa ukuze baqinisekise imiphumela.
Isivivinyo sendawo esibukwayo esibukwayo siyithuluzi elinamandla kakhulu. Noma kunjalo, imiphumela ixhomekeke ekutheni umuntu ohlolwayo. Uma umuntu eseqedile okungenani ukuhlolwa okulodwa, ngokuvamile benza kangcono isikhathi sesibili nxazonke. Ukuhlolwa kokugcina akuvame ukwenziwa kuze kube yilapho isiguli siphindaphinda ukuhlolwa okungenani kabili futhi ngezinye izikhathi ngisho nangesithathu. Ngenxa yokuthi amayunithi wokuhlolwa kwendawo okuzenzekelayo ayenayo ikhompyutha kuwo, ukwethembeka kokuhlolwa kungalandelwa. Izibalo ezithile zibalwa ukulawula iphutha lomsebenzisi futhi zinike udokotela okuthile okuthembekile.
