Isifo Sikashukela Cataract

Ama-Cataralog ayisifo esibonakala ngokugcwala kwamalensi. Imvamisa, ilensi ibonakala ngokuphelele ngoba iphatha ukujula kokukhanya ku-retina futhi isebenza njengelensi yokukhanya. Uma le ngxenye yamathuluzi okubona amehlo iba namafu, umbono womuntu wehla kakhulu. Ngaphandle kokwelashwa, isiguli singaze siphuphutheke ngenxa yokuqubuka kwekati. Ngenxa yokuthi ngesifo sikashukela zonke izinqubo ezibuhlungu emzimbeni zinzima ngokwengeziwe, kubalulekile ukuqaphela lesi sifo ngesikhathi bese uqala ukwelashwa.

Izinhlobo zezifo nezimbangela

Izimbangela eziqondile zokuthuthuka kwama-cataralog kwisifo sikashukela (njengoba, ngeshwa, kwamanye amaqembu eziguli) namanje akwaziwa. Kepha kunezici ezicatshangelwe ezingase zibange ukugula kulokhu. Kakhulu kufaka phakathi ubudala nobudala. I-50% yabantu abangaphezu kweminyaka engama-60 itholakala ngokugcwala kwama-lens, futhi ngaphezulu kweminyaka engama-80, lesi sifo sitholakala kwiziguli ezingama-90-100%. Ama-Cataralog ashukela ashukela angahlukaniswa ngezinhlobo ezi-2:

• isifo esibangelwa izinguquko ezihlobene nobudala bokuwohloka okuhlobene nobudala, okuqhubeka ngokushesha ngenxa yesifo sikashukela;
• ukugula okuqhamuke ngokuqondile ngenxa yokuphazamiseka kwe-carbohydrate metabolism.

Uhlobo lokuqala lwe-cataract luvame ukutholakala kwisifo sikashukela sohlobo 2, ngoba isimo sempilo yeso somuntu siba sikhulu ngeminyaka. Ngokuphikisana nesizinda sokwanda ushukela wegazi, zonke izinqubo ze-pathological emzimbeni ziqhubeka kakhulu. Ngenxa yesifo sikashukela, ukuhanjiswa kwegazi okujwayelekile esweni kuphazamisekile futhi nokuhamba kwezicubu zezinzwa kule ndawo kuya konakala. Ngaphandle kokulawulwa nokwelashwa, lokhu kungaholela ekulimazelweni okubonakalayo okukhulu, kuze kube ubumpumputhe.

Izimpawu ze-Diabetesic Retinopathy

Ukwelashwa kwangempela kwesifo sikashukela kungakhula ngisho nakubantu abasha abanenkinga yesifo sikashukela esincike ku-insulin. Kwesinye isikhathi lesi sifo sihlanganiswa ne-retinopathy (izinguquko ezibuhlungu ku-retina) noma iba yodwa. Imvamisa, ama-opacities akha odongeni lwangemuva lwamalensi, futhi nangokwelashwa okufika ngesikhathi, akhuphuki. Ngenxa yokusetshenziswa kwamaconsi okusekela kwamehlo kanye nokujwayelekile kwamazinga kashukela egazini, lesi sifo singamiswa ekuqaleni kokukhula kwawo.

Uma ukuphazamiseka kokuqala kungatholakali ngesikhathi, lesi sifo singasakazekela kakhulu kulensi futhi sibangele izinkinga ezinkulu zamehlo. Izehlakalo zokuwohloka kwesibonakaliso se-acuity ezigulini ezinesifo sikashukela sohlobo loku-1 ziphakeme izikhathi eziphindwe kathathu nge-cataralog kune-retinopathy yesifo sikashukela.

Uhlolo lwe-Ophthalmologist izivivinyo kumele ulusebenzele bonke abanesifo sikashukela, kungakhathalekile ngobudala nobunzima bokuthi lesi sifo sibangelwa yini

Izimpawu

Ekuqaleni kokukhula kwesifo, izimpawu zingaba ukufiphala noma kungabikho ngokuphelele. Njengoba lesi sifo siqhubeka, isiguli siqala ukuphazanyiswa ukubonakaliswa okunjalo:

• ukubonakala kwamabala kanye nezinhlansi phambi kwamehlo;
• kwehlise i-acuity ebonakalayo;
• ukuzwela okukhulayo kokukhanya okukhanyayo;
• ukuphindaphindeka kwezinto ngezikhathi ezithile;
• umbono ofiphele lapho usebenza kukhompyutha, ufunda izincwadi nokubhala;
• wehlise umbono wesikhathi sokuhlwa;
• umuzwa wesembozo sokukhanya phambi kwamehlo.

Njengoba kunendawo ebanzi yomonakalo, ama-catararat angazibonakalisa ngezimpawu ezinobungozi ezifana nalezi:

• ukwehla okukhulu kwe-acuity ebonakalayo;
• ukusithwa kwemfuzi, ukwakheka kwamabala amhlophe kuyo;
• amandla okubona ama-silhouette kuphela wezinto;
• ubumpumputhe.

Ukwelashwa okuqondayo

Akunakwenzeka ukubuyisa ngokuphelele ukuvela kwe-lens ngamaconsi noma eminye imithi yasendaweni. Ukuqubuka okuvelayo akuxazululi kusuka ekusetshenzisweni kwemithi yabantu, cishe akuthinteki yi-physiotherapy kanye nokuhlungwa kwamehlo. Kodwa ngenxa yezinketho zokwelashwa okulondolozayo, unganciphisa ngokweqile ijubane lesifo futhi uthuthukise ukuhamba kwezinqubo ze-metabolic ezicutshini eziseduze.

Kukuso siphi isigaba sokonakala kwesifo sikashukela okufanele kusetshenziswe amaconsi akhethekile? Umphumela omuhle kakhulu ungatholakala ngokuwusebenzisa ezigabeni zokuqala zokuthola inkinga, ngenkathi usayizi we-turbidity nendawo ephelele yesilonda incane. Kukhona nemithi ekhethekile esetshenziselwa ukugwema. Banciphisa ubungozi bezinkinga zamalensi ezigulini nasebekhulile abancane.

Ukwelashwa kwezidakamizwa, izixazululo zamavithamini, ama-amino acid nezakhi zomkhondo ezilandelanisa usawoti ezijwayelekile zisetshenziswa kahle kwezakhi zomzimba Ukulwa nendlala komoya-mpilo, amaconsi anama-antioxidants nama-enzyme asetshenziswa ukwenza ngcono ukusebenza kwezinqubo zokushintshanisa ngerhasi engaphakathi. Izidakamizwa ezinjengalezi zingasiza ekulweni nokuqubuka kwama-cataralog hhayi nje kuphela, kodwa futhi nesifo sikashukela se-diabetes, uma ngabe sesiqalile ukukhula.

Ngokusetshenziswa okuhlelekile nokwenziwa okufika ngesikhathi kokwelashwa, amaconsi eso asiza ukuvimbela ukonakala kwe-cataract.

Ingabe ukuhlinzwa kuyadingeka njalo?

Ukuhlinzwa akudingeki ngaso sonke isikhathi ukuphatha izinhlungu zamehlo, yize, empeleni, ukuphela kwendlela yokuxazulula inkinga. Ngesikhathi sokuhlinzwa, ilensi ithathelwa indawo ngumlingani waso wokufakelwa, ngenxa yokuthi umbono wesiguli ubuyiselwa. Kepha ezigabeni zokuqala, ngosizo lwemithi kanye nokulawula ushukela wegazi, ungazama ukumisa ukuthuthukiswa kwalesi sifo. Uma i-cataract ingaqhubeki, khona-ke isiguli sinawo wonke amathuba okugcina umbono ojwayelekile isikhathi eside ngaphandle kokuhlinzwa.

Ukungenelela kokuhlinzwa kukuvumela ukuba ukhiphe i-cataralog ezimweni ezisezingeni eliphakeme, kepha ukuqaliswa kwayo kungenzeka kuphela lapho kungekho khona ukuphikisana. Isibonelo, i-retinopathy enzima, ethinta iningi le-retina, ingaba yisithiyo esikhulu ekuhlinzweni. Ubunzima buqhamuka nokukhula kwemithambo yegazi emincane ku-iris yeso. Ngaphansi kwalezi zimo, umbuzo wokufanele ukwelashwa okuhlinzwa kufanele unqunywe ngochwepheshe bezokwelapha abaningana ngesisekelo sokuhlolwa kwenhloso kanye nokuhlolwa okunamandla.

Okunye ukwephula umthetho wokuhlinzwa yisifo seso sokuvuvukala. Ekuqaleni, kuyadingeka ukuqeda inqubo ebabayo ngosizo lokwelashwa kanye nezinqubo zasendaweni, bese kuphela uhlela ukubuyiselwa kwamalensi. Amasu wokuhlinzwa anamuhla avumela ukungenelela ngaphansi kwe-anesthesia yendawo kanye nendawo encanyana yokufikelwa. Ngale njongo, kusetshenziswa imishini ye-laser kanye nama-analog wokufakelwa welensi elenziwe ngezinto ezinokwethenjelwa zepolymer.

Ukuvimbela

Njengoba izimbangela eziqondile zekati ezingaqondakali zingcacile, ukuvikela kwalesi sifo kuhlahlela endleleni yokuphila enempilo, kulawula ushukela wegazi kanye nokusetshenziswa kwezisebenzi zokuqinisa. Kukhona amaconsi wamehlo angasetshenziswa hhayi kuphela ekwelashweni, kodwa nasekuvimbeleni ukugula. Udokotela wamehlo kuphela okufanele abalandise ngemuva kokuhlolwa okuningiliziwe kwezinto zokusebenza nomlando we-ocular. Noma yimiphi imizamo yokuzelapha (kufaka phakathi ukusebenzisa amakhambi abantu) ingaba yingozi enkulu, futhi imvamisa iholela ekuwohlokeni okubukwayo.

Bonke abanesifo sikashukela kudingeka bahlolwe izivivinyo ngudokotela wezamehlo okungenani kanye ezinyangeni eziyisithupha. Ama-Cataralog kwisifo sikashukela angadala ukuvakashela kaningi kudokotela, kepha kuyadingeka ngempela ukugcina umbono nokugcina amehlo enempilo. Ukuhambisana nokudla kanye nokuqaliswa kwezinye izincomo zikadokotela ozifundayo kunciphisa ubungozi bokuthola izinkinga eziningi zesifo sikashukela, kubandakanya nezifo zamehlo.
