Luyintoni uvavanyo oluqhelekileyo lweOphthalmic?

Uvavanyo oluqhelekileyo lwamehlo luluhlu olubanzi lovavanyo olwenziwe ngugqirha wamehlo. I-ophthalmologist ngugqirha ogxile kwimpilo yamehlo. Olu vavanyo lukhangela umbono wakho kunye nempilo yamehlo akho.

Kutheni le nto Ndidinga uViwo lweOphthalmic?

NgokweKliniki yaseMayo, abantwana kufuneka benze uvavanyo lwabo lokuqala phakathi kweminyaka emithathu ukuya kwemihlanu. Abantwana kufuneka bavavanywe namehlo ngaphambi kokuba baqale ibanga lokuqala kwaye kufuneka baqhubeke nokufumana iimviwo zamehlo qho emva kweminyaka emibini. Abantu abadala abangenangxaki yokubona kufuneka bajonge amehlo rhoqo kwiminyaka emihlanu ukuya kweli-10. Ukuqala kubudala beminyaka engama-40, abantu abadala kufuneka babe novavanyo lwamehlo rhoqo emva kweminyaka emibini ukuya kwemine. Emva kweminyaka engama-65, fumana uviwo minyaka le (okanye nangaphezulu ukuba unemicimbi ngamehlo okanye umbono).

Abo baneengxaki zamehlo kufuneka bajonge kugqirha malunga neemviwo.

Ndizilungiselela njani iimviwo zamehlo?

Akukho lungiselelo lukhethekileyo lufunekayo ngaphambi kovavanyo. Emva koviwo, ungadinga umntu wokukuqhubela ekhaya ukuba ugqirha wakho wandisile amehlo akho kwaye umbono wakho awukabuyeli esiqhelweni. Zisa iiglasi zelanga kwiimviwo zakho; emva kokuxutywa, amehlo akho aya kukhanya ngokukhawuleza. Ukuba awunazo izibuko zelanga, iofisi kagqirha iya kukubonelela ngento yokukhusela amehlo akho.

Kwenzeka ntoni ngexesha loviwo lweOphthalmic?

Ugqirha wakho uya kuthatha imbali epheleleyo yamehlo kubandakanya iingxaki zakho zombono, naziphi na iindlela zokulungisa onazo (umzekelo, iiglasi okanye iilensi zonxibelelwano), impilo yakho iyonke, imbali yosapho, kunye namayeza akhoyo ngoku.

Baza kusebenzisa uvavanyo lokutshixa ukujonga umbono wakho. Uvavanyo lokukhutshwa kuxa ujonga isixhobo esineelensi ezahlukeneyo kwitshathi yamehlo engama-20 eenyawo ukuze uncede ukumisela nabuphi na ubunzima bombono.

Kananjalo baya kuwaluvula amehlo akho ngamathontsi wamehlo ukwenza ukuba abafundi babe bakhulu. Oku kunceda ugqirha wakho ukujonga ngasemva kweliso. Amanye amalungu oviwo angabandakanya ukujonga umbono wakho-ntathu (stereopsis), ukujonga umbono wakho wendlela ukubona ukuba ubona njani ngaphandle kokujolisa ngqo, kunye nokujonga impilo yemisipha yakho yamehlo.

Olunye uvavanyo lubandakanya:

• uviwo lwabafundi bakho ngesibane ukubona ukuba baphendula ngokufanelekileyo na
• Uviwo lwe-retina yakho ene-lens ekhanyisiweyo ekhanyisiweyo ukuze ubone impilo yemithambo yegazi kunye ne-optic nerve yakho
• Uvavanyo lwesibane, olusebenzisa esinye isixhobo sokukhanyisa ukukhangela ijwabu leso, i-cornea, i-conjunctiva (inwebu encinci egubungele abamhlophe bamehlo), kunye ne-iris
• I-tonometry, uvavanyo lwe-glaucoma apho ukukhupha komoya okungenabuhlungu kwiliso lakho ukulinganisa uxinzelelo lolwelo ngaphakathi kwiso lakho
• uvavanyo lokungaboni kakuhle, apho ujonga khona kwizangqa zamachaphaza amibala-bala ngamanani, iisimboli, okanye iimilo kuzo

Zithetha Ntoni Iziphumo?

Iziphumo eziqhelekileyo zithetha ukuba ugqirha wakho akafumananga nto engaqhelekanga ngexesha lovavanyo lwakho. Iziphumo eziqhelekileyo zibonisa ukuba:

• ube ne-20/20 (yesiqhelo) umbono
• iyakwazi ukwahlula imibala
• abanazimpawu zeglaucoma
• azikho ezinye izinto ezingaqhelekanga ezinomthambo we-optic, i-retina, kunye nezihlunu zamehlo
• azinazo ezinye iimpawu zesifo samehlo okanye iimeko

Iziphumo ezingaqhelekanga zithetha ukuba ugqirha wakho ufumene ingxaki okanye imeko enokufuna unyango, kubandakanya:

• ukungaboni kakuhle okufuna iiglasi zokulungisa okanye iilensi zonxibelelwano
• i-astigmatism, imeko ebangela ukungaboni kakuhle ngenxa yemilo ye-cornea
• i-duct evaliweyo, ukuvalwa kwenkqubo ehambisa iinyembezi kwaye ibangele ukukrazula okugqithisileyo)
• iliso elonqenayo, xa ingqondo namehlo zingasebenzi kunye (eziqhelekileyo ebantwaneni)
• strabismus, xa amehlo engangqinelani ngokufanelekileyo (aqhelekileyo ebantwaneni)
• usulelo
• umothuko

Uvavanyo lwakho lunokuveza iimeko ezinzima. Oku kunokubandakanya

• Ukwehla kobudala be-macular degeneration (ARMD). Le yimeko embi eyonakalisa i-retina, isenza kube nzima ukubona iinkcukacha.
• I-Cataract, okanye ukusithwa kwe-lens ngobudala obuchaphazela umbono, kukwayimeko eqhelekileyo.

Ugqirha wakho unokufumana i-corneal abrasion (ukukrola kwi-cornea enokubangela ukungaboni kakuhle okanye ukungonwabi), imithambo eyonakeleyo okanye imithambo yegazi, umonakalo onxulumene neswekile (isifo seswekile), okanye i-glaucoma.
