I-nertic optic iqukethe izintambo eziningi ezinomthwalo wokudlulisela ulwazi olubonakalayo ezikhungweni zobuchopho lapho kusetshenzwa khona. Eqinisweni, ukuphelela kwesithombe esibhekile kuxhomeke kulo, ubukhali nobukhali balokho umuntu akubonayo. Isimo lapho lezi zicabha ziqala ukufa noma ezindaweni ezingenakunyakazeka, zabizwa ngokuthi i-atrophy ye-optic nererve. Lesi sifo sithinta kokubili abantu asebaneminyaka yabo kanye nabantu abasha.
Iyini i-atrophy ye-nertic optic?
Lezi zindlela zokukhubazeka kuyinkqubo yokwehliswa kwezicubu ezinamafutha we-optic nererve.
Lesi sifo sihlukaniswa sibe yi-atrophy eyinhloko - eyayizimele, futhi eyesibili, eyasuka ngemuva kokuqhubeka kwezinye izifo.
Ngaphezu kwalokho, ukukhubazeka kungaba okuphelele noma okuyingxenye, okuhlangene okulodwa kanye nohlangothi olulodwa (okukodwa noma kokubili amehlo kuthinteka), futhi futhi okuqhubekayo noma okumile (kungakhathaliseki ukuthi lesi sifo siphuthuma nokuthi sisheshe kanjani).
I-atrophy ephansi ye-optic nesibindi - izimpawu
Izimpawu zokuguquka ziyahlukahluka kuye ngokuthi ifomu elikhona lesifo kanye nokuba khona noma ukungabikho kokuqhubeka kwayo.
I-atrophy eyinhloko ibhekwa yi-pallor ye-optic nererve disc, imingcele yayo ecaciswe ngokucacile. Ku-retina kunciphisa okuphawulekayo kwemithwalo yegazi egazi. Ngesikhathi esifanayo, umbono wesiguli uyancipha kancane kancane, umbono wemibala kanye ne-shades iyaba nzima.
I-atrophy yesibili ye-nertic optic ihluke kufomu echazwe ngenhla ukuthi i-disc ayinayo imingcele ecacile, ihlukumezekile. Ekuqaleni kwesifo, imithanjeni ihlanjululwa. Umbono ngalolu hlobo lwesifo lubaluleke nakakhulu - kukhona okuthiwa yizimpumputhe (ukuwa kwe-hemianopic). Ngokuhamba kwesikhathi, umuntu angakwazi ukulahlekelwa ngokuphelele amandla okubona.
I-atrophy ekhethekile futhi ephelele ye-nertic optic
Njengalokhu okuvela egameni lezinhlobo ezihlukanisiwe ze-pathology, lezi zinhlobo zesifo ziyahlukahluka ngezinga lokuguqulwa kwesisindo futhi, ngokufanayo, ukuqonda ulwazi olubonakalayo. Ngomonakalo okhethekile emafabeni, umbono ubhekene nokuphazamiseka kuphela, nakuba kubaluleke nakakhulu, futhi ubumpofu obunembile butholakala.
I-Atrophy ye-optic nerve ibangela
Kumele kuqashelwe ukuthi okuwukuphela kwento eholele ekuthuthukiseni lesi sifo ngesimo salo esiyinhloko yi-heredity.
Izimbangela ze-atrophy yesibili:
- izifo ze-optic nerve (ukutheleleka, umonakalo onobungozi, ukuhlukumezeka, ukuphazamiseka kokujikeleza, ukuqhuma kwesisindo);
- i-glaucoma ;
- i-neuritis;
- i-retinal pathology;
- izifo zobuchopho, kuhlanganise nezicubu;
- izifo zemithanjeni yegazi (hypertension, arrhythmia, isifo sokuqina kwegazi);
- ama-virus;
- encephalitis.
I-Atrophy ye-nertic optic - ingabe kuhlinzekwa ukuhlinzwa?
Akunakwenzeka ukubuyisela izintambo ezimele, ngakho-ke, ukwelashwa kwalesi sifo kugxile ekulondolozeni izinkomba ezikhona zombono nokuvimba ukuqhubeka kwesifo.
Ukwelapha, okokuqala, kuqala ngokuqeda imbangela ye-atrophy, uma lokhu kungesilo ifa. Emva komuthi wokwelashwa wendabuko ohlanganisa izidakamizwa ze-vasodilator, ukuhambisa kwegazi kwe-tonic
Enye yezindlela ezintsha kakhulu zokwelapha lesi sifo iwukuthi ukufakelwa kwe-electrostimulator ngokuqondile ngokuqondile kweso. Naphezu kokusebenza kahle kwalendlela, kudinga ukutshala izimali ezinkulu, kuthatha isikhathi eside sokuvuselela, futhi ukufaka ngokwakho kusebenza iminyaka eminingana kuphela.
