Ingabe unezinto ezincane ezifana nezinkanyezi emehlweni akho? (I-Asteroid Hyalosis) Ake sixoxe ngakho!

Wake wazibona izinto ezincane ezimnyama zihamba phambi kwamehlo akho, njengezintambo zesicabucabu? Noma ngezinye izikhathi uzizwa sengathi amehlo akho afiphele kancane? Lezi ngezinye izikhathi kungaba izinto ezivamile eziza nokuguga. Kodwa namuhla sizokhuluma ngesimo samehlo esincane esingesabekayo kangako, futhi abantu abaningi abazi ngaso. Sisibiza ngokuthi i-asteroid hyalosis.

Iyini ngempela i-Asteroid Hyalosis?

Kalula nje, i-asteroid hyalosis ukwakheka kwezinhlayiya ezincane, ezicwebezelayo, eziphuzi, noma izinto eziwuphuphu, ngaphakathi kweso lakho. Cabanga ngakho njengezinkanyezi ezikhazimula esibhakabhakeni ebusuku, kodwa lokhu kungaphakathi kweso lakho. Empeleni lokhu akulimazi ezimweni eziningi , ngakho ezimweni eziningi akukho ukwelashwa okudingekayo.

Lezi zinhlayiya ezincane zakha into ecacile, efana nejeli ngaphakathi kweso ebizwa ngokuthi i-vitreous. Le vitreous yiyo esiza iso lethu ukuthi ligcine isimo salo esiyindilinga. Ngokumangalisayo, abantu abangaphezu kuka-80% bahlakulela lesi simo ngeso elilodwa kuphela.

Nakuba kuhlukaniswa njengesimo "sokuwohloka" esihlala njalo, esiqhubekayo, abantu abaningi abazi nokuthi banaso . Lokho kungenxa yokuthi ngokuvamile asithinti umbono wakho noma sibangele ezinye izimpawu. Lesi sithako esikhanyayo ngaphakathi kweso asibonakali ngaphandle kokuthi ubambe isibani bese ubheka eduze.

Ngezinye izikhathi, le asteroid hyalosis ingabangela ukuthi ubone izinto ezintantayo embonweni wakho (Eye Floaters noma Myodesopsias). Ama-Floaters avame ukwenzeka ngemva kweminyaka engu-50, futhi ayingxenye evamile yokuguga. Kodwa umehluko omkhulu phakathi kwalokhu okubili ukuthi ku-asteroid hyalosis, kunezinhlayiya ezicwebezelayo ngaphakathi kweso lakho, kanti kwezinye izimo, ama-floaters angenzeka ngaphandle kwezinhlayiya ezinjalo.

Sivame kangakanani lesi simo?

Ngokusho kodokotela, lesi simo esibizwa ngokuthi i-asteroid hyalosis sivame kakhulu . Sivame kakhulu kubantu abangaphezu kweminyaka engama-60. Ingozi yalesi simo iyanda njengoba iminyaka ikhula.

Ziyini izimpawu?

Akumangalisi yini? I-Asteroid Hyalosis ivame ukungabi nazimpawu . Abantu abaningi bathola ukuthi banayo lapho udokotela ebona ngengozi lezi zinhlayiya zikhanya emehlweni akho, kungaba ngesikhathi sokuhlolwa okuvamile kwezokwelapha noma ngesikhathi sokuhlolwa kwamehlo.

Kodwa-ke, uma kuvela izimpawu, ngokuvamile ziba zincane kakhulu . Abanye abantu bangase babe nombono ofiphele noma ukwanda kwenani lama-floating emehlweni abo.

Kungani lokhu kwenzeka? Yiziphi izizathu?

Eqinisweni, ochwepheshe abakakazi kahle ukuthi yini ebangela i-asteroid hyalosis.Kodwa, ngithole okuncane ngalokho okwenzekayo.

Lezi zidumbu ze-asteroid ziqukethe amaminerali afana ne-calcium ne-phosphorus, kanye nama-fatty compounds abizwa ngokuthi ama-lipids. Amakristalu akha lezi zinhlayiya afana namatshe enyongo kanye namatshe ezinso akheka emizimbeni yethu. Abanye abacwaningi bakholelwa ukuthi kungase kube nokuxhumana phakathi kwezinto ezibangela amatshe ezinso kanye namatshe enyongo kanye nalesi sifo se-asteroid hyalosis. Kodwa-ke, kudingeka ucwaningo olwengeziwe ukuqinisekisa lokhu.

Cabanga nje, lezi zidalwa ze-asteroid zincane kakhulu . Ububanzi bazo obujwayelekile bungama-micrometer angu-180. Kodwa ezinye zingaba zincane njengama-micrometer angu-3 futhi zibe zinkulu njengama-micrometer angu-280. (Ukuze kube lula ngawe ukuqonda, kune-micrometer engu-1000 ku-millimeter eyodwa, kanti ububanzi bomucu wezinwele ekhanda lethu buvame ukuba ngama-micrometer angu-100!).

Lezi zinhlayiya azingeni esweni, ngoba i-vitreous ifana nejeli. Njengejeli enezingcezu zezithelo ezinamathele lapha nalaphaya, lezi mizimba ye-asteroid isendaweni efanayo. Zingase zinyakaze futhi zinyakaze kancane uma ushukumisa amehlo akho, kodwa ngokuvamile zihlala lapho zikhona.

Ubani onamathuba amaningi okuthuthukisa lokhu? (Izici eziyingozi)

Kunezici ezimbili eziyinhloko ezibangela lokhu abacwaningi abakwazile ukuzithola:

• Uma uneminyaka engaphezu kwengu-60 ubudala, kungenzeka kakhulu ukuthi ube ne-asteroid hyalosis.
• Cishe abantu abangu-60% abanalesi simo bangamadoda .

Ngaphezu kwalokho, abantu abanezifo ezithile batholwe benale asteroid hyalosis. Okungukuthi:

• Isifo Sikashukela Sohlobo 2.
• Izinga le-cholesterol ephezulu egazini (i-Hyperlipidemia).
• Umfutho wegazi ophezulu (i-Hypertension).

Kodwa-ke, ochwepheshe abakaqiniseki ukuthi lezi zifo zibangela i-asteroid hyalosis . Kodwa-ke, izifundo zithole ukuthi i-asteroid hyalosis ivame kakhulu kubantu abanalezi zifo.

Ukubona kanjani lokhu?

Esikhathini esiningi, ukukhanya kwalezi zidalwa ze-asteroid kubonakala ngamehlo enyama. Noma, kungabonakala lapho udokotela eyibheka ngedivayisi encane ephathwa ngesandla ebizwa ngokuthi i-ophthalmoscope ngesikhathi sokuhlolwa okuvamile. Le divayisi inokukhanya okuncane kanye nengilazi encane ngaphezu kwayo udokotela ayibukayo.

Uchwepheshe wamehlo, kungaba udokotela wamehlo noma udokotela wamehlo, angathola i-asteroid hyalosis ngesikhathi sokuhlolwa kwamehlo okuvamile.

Yiziphi izivivinyo ezenziwayo ngalokhu?

Ngokuvamile ungabona ukuthi une-Asteroid Hyalosis ngokubheka amehlo akho. Udokotela wamehlo angenza nokuhlolwa okubizwa ngokuthi "Slit Lamp Exam," kodwa kungaba nzima kancane ukubona imizimba ye-asteroid ngalokho. Lokhu kungenxa yokuthi "Slit Lamp" inokukhanya okukhanyayo kakhulu kune-"Ophthalmoscope," ngakho ukukhanya okwengeziwe kungabonakala kulezi zinhlayiya futhi ungase ungakwazi ukuzibona kahle. (Kufana nokuthi uma uvula izibani zemoto yakho ezinezibani eziphakeme esimweni sezulu esibi, awukwazi ukubona phambili.)

Nakuba lezi zivivinyo zingasiza ekuxilongeni i-asteroid hyalosis, udokotela wakho angase acele izivivinyo ezengeziwe ukuze akhiphe ezinye izimo ezingase zibe nezimpawu ezifanayo. Lezi zivivinyo zifaka:

• I-Fluorescein Angiography: Lokhu kusiza ukuthola izinkinga ezifana ne-retinopathy ehlobene nesifo sikashukela, okuwukwakheka kwemithambo yegazi emisha esweni ngenxa yesifo sikashukela.
• I-Optical Coherence Tomography: Lokhu kungasetshenziswa futhi ukuxilonga i-retinopathy ehlobene nesifo sikashukela, noma ukuthola ezinye izinkinga ezifana ne-glaucoma kanye nezimila zamehlo.

Ingabe kukhona ukwelashwa? Kwenziwani?

Izindaba ezinhle kakhulu ukuthi ezimweni eziningi, i-asteroid hyalosis ayidingi ukwelashwa . Akuyona yini impumuzo leyo?

Ukwelashwa kuvame ukudingeka kuphela uma lesi simo sibangela ukuthi umbono wakho ufiphale futhi kube nzima ukubona. Kuleso simo, ukwelashwa kuwukuhlinzwa kwamehlo okubizwa ngokuthi i-vitrectomy. Lokhu kuhlinzwa kuhilela ukususa i-vitreous enamafu ngaphakathi kweso lakho bese uyishintsha ngento entsha.

Ngokuvamile, kufakwa uketshezi olunosawoti, uwoyela we-silicone, noma ibhamuza legesi. Zonke lezi zinto zisiza iso ukuthi ligcine isimo salo. Uma kufakwa uwoyela we-silicone, kudingeka olunye ukuhlinzwa ukuze kususwe uwoyela. Uma kufakwa usawoti noma ibhamuza legesi, akudingeki olunye ukuhlinzwa, ngoba umzimba wakho kancane kancane ukhiqiza uketshezi olusha lwe-vitreous bese uluthatha indawo yalo.

Ingabe zikhona izinkinga ngemva kokuhlinzwa?

Njengoba i-vitrectomy iyindlela yokuhlinzwa, njenganoma yikuphi okunye ukuhlinzwa, ezinye izinkinga zingavela. Lezi zinkinga zifaka:

• Ukutheleleka.
• Ukopha.
• Ubuhlungu bamehlo.
• I-retina edabukile noma ehlukanisiwe.
• Ama-cataract (amasha noma amabi kakhulu ama-cataract akhona).
• Kudingeka ngiphinde ngihlinzwe amehlo.
• Ukulahlekelwa noma ukuncipha kombono (lokhu kwenzeka kaningi kakhulu).

Lokhu kungase kuzwakale kusabisa, kodwa khumbula ukuthi izinkinga ezinkulu azivamile .

Kuzothatha isikhathi engingakanani ukuphola?

Ngokuvamile kuthatha cishe amasonto amabili kuya kwamane ukululama ngemva kokuhlinzwa kwe-vitrectomy.Kodwa eminye imiphumela ingathatha isikhathi eside ukuxazululeka. Isibonelo, uma ufaka ibhamuza lomoya esweni lakho, kungathatha amasonto ambalwa ukuthi linyamalale futhi kwakheke uketshezi olusha lwe-vitreous.

Uma nginalesi simo, yini okufanele ngiyilindele?

Eqinisweni, abantu abaningi abane-Asteroid Hyalosis abazi nokuthi banayo . Ezimweni eziningi, azikho izimpawu.

Kodwa-ke, uma unesimo esibi kakhulu salesi simo, ungase ubone izinto eziningi ezintantayo embonweni wakho noma umbono wakho ungase uzwakale ungacacile. Nakuba lezi zimpawu zingeyingozi, ngezinye izikhathi zingacasula kancane, noma ngezinye izikhathi zenze kube nzima ukuzibona.

Lokhu kuzohlala isikhathi esingakanani?

I-Asteroid Hyalosis ivame ukwenzeka ngemva kweminyaka engu-60. Uma isiqalile, ngaphandle kokuthi uhlinzwe i-vitrectomy bese ushintsha i-vitreous engaphakathi kweso, ihlala unomphela .

Ikusasa lizosiphathelani? (I-Outlook)

Nakuba i-Asteroid Hyalosis iyisimo esiwohlozayo ngokwezobuchwepheshe, njengoba kushiwo ngaphambili, abantu abaningi abanazo izimpawu . Ngakho-ke, ochwepheshe bayibheka njengesimo esingenabungozi. Lokho kusho ukuthi akukho okufanele ukhathazeke ngakho.

Ingabe lokhu kungavinjelwa? Ingabe zikhona izindlela zokunciphisa ingozi?

Ngeshwa, i-asteroid hyalosis yenzeka ngokungalindelekile futhi ngenxa yezizathu ochwepheshe abangakaziqondi ngokugcwele . Ngakho-ke, okwamanje ayikho indlela yokuyivimbela noma yokunciphisa ingozi yokuyithola.

Ngizinakekela kanjani?

Uma ubona noma yiziphi izinguquko kancane kancane ekuboneni kwakho, ikakhulukazi ukubona okufiphele noma okunciphile, kufanele nakanjani ubonane nochwepheshe wamehlo . Banganquma ukuthi yini ebangela ushintsho nokuthi ludinga ukwelashwa (uma kudingeka).

Ngenxa yokuthi abantu abaningi abane-asteroid hyalosis abanazo izimpawu futhi abadingi ukwelashwa, izimpilo zabo ngeke zishintshe kakhulu ngemva kokuxilongwa. Udokotela wakho wamehlo uzokutshela ukuthi yini ongayenza ukuze unakekele amehlo akho futhi uvimbele ezinye izinkinga.

Kufanele uye nini kudokotela? Kufanele uye nini egumbini lezimo eziphuthumayo?

Uma une-Asteroid Hyalosis, kufanele ube nokuhlolwa njalo nodokotela wamehlo. Bazokutshela ukuthi kufanele uhlolwe kangaki amehlo akho. Udokotela wakho uzokutshela nokuthi udinga ukuhlolwa kaningi ukuze aqaphe noma yiziphi izinguquko noma izinkinga emehlweni akho.

I-Asteroid Hyalosis akuyona inkinga eyingozi, futhi ayibangeli izinkinga. Kodwa-ke, ngezinye izikhathi ingahlotshaniswa nezinye izimo ezingathi sína . Ngakho-ke, kufanele ufune usizo lwezokwelapha ngokushesha uma uhlangabezana nezimpawu ezilandelayo, izinkinga, noma izinguquko embonweni wakho:

• Ukulahlekelwa umbono ngokuzumayo.
• Ukukhanya okungazelelwe (i-Photopsia).
• Ukuvela kwama-blackhead noma ama-floater, ikakhulukazi uma evela ngokuzumayo noma ekhula ngenani.
• Umbono ofiphele (umbono oyingxenye noma ophelele).

Khumbula, lezi zimpawu kungenzeka zingabangelwa yi-asteroid hyalosis, kodwa zibangelwa ezinye izimo ezibucayi. Ngakho-ke, kubaluleke kakhulu ukubona udokotela ngokushesha okukhulu.

Kungani lokhu kubizwa ngokuthi 'i-asteroid'?

I-Asteroid Hyalosis ingase izwakale njengenkinga yesikhala, akunjalo? Kodwa kungenxa yesimo esingavamile olimini lwasendulo. Igama elithi "asteroid" livela kwelesiGriki sasendulo, elisho "njengenkanyezi." Liqanjwe ngokuthi uma uliphakamisa esweni lakho bese ulibheka ngokukhanya, lezi zinhlayiya ezingaphakathi kweso lakho zibukeka njengezinkanyezi ezikhanya esibhakabhakeni sasebusuku.

Uma ubona ukuthi amehlo akho aya ngokuya eqala ukuntanta, noma ukubona kwakho kuya ngokuya kufiphala, kufanele nakanjani ubonane nochwepheshe wamehlo. Bazohlola amehlo akho futhi banqume ukuthi yini ebangela ushintsho. Uma bethola ukuthi une-asteroid hyalosis, cishe bazohlola nezinye izimo zamehlo ezingase ziyibangele.

I-Asteroid Hyalosis ivame ukwenzeka kubantu abaneminyaka engaphezu kwengu-60. Ngenhlanhla, ayikho indlela yokwazi ukuthi unayo ngaphandle kokubukeka okukhazimulayo. Iningi labantu alinazo izimpawu futhi alidingi ukwelashwa . Okuwukuphela kwento eshintshayo kubantu abaningi ukuthi amehlo abo abukeka “egcwele izinkanyezi”!

Okokugcina, izinto okufanele uzikhumbule

Ngakho-ke, manje usuyazi okuningi nge-Asteroid Hyalosis. Izinto ezibaluleke kakhulu yilezi:

• Lesi yisimo esivame kakhulu lapho umuntu ekhula, ikakhulukazi ngemva kweminyaka engama-60 .
• Esikhathini esiningi , akukho okubi, futhi izimpawu azivamile ukuvela .
• Abantu abaningi abadingi ukwelashwa .
• Uma ubona noma yiziphi izinguquko ezintsha ekuboneni kwakho, njengokungacaci noma ukwanda kwezimbobo ezintantayo, qiniseka ukuthi ubona udokotela wamehlo .
• Ungesabi uma uzwa leli gama, liyigama nje elinikezwa izinhlayiya ezincane ezicwebezelayo ngaphakathi kweso.

Kubalulekile ukunakekela amehlo akho, ngakho ungakhohlwa ukuhlolwa amehlo njalo .
