Ngaba ubona ihlabathi ngeendlela ezimbini ezahlukeneyo ngamehlo omabini? Makhe sithethe nge (Aniseikonia)!

Ngaba wakha wavakalelwa kukuba oko ukubona kwelinye iliso kukhulu okanye kuncinci kunokubona kwelinye iliso, okanye ukuba ukucaca kwahlukile? Khawuthelekelele, xa uqhuba imoto endleleni, imoto oyibona kwelinye iliso ibonakala inobukhulu obahlukileyo kancinci kwelinye iliso, okanye xa ufunda incwadi, oonobumba babonakala betsalelwe ecaleni. Oku kungaba luphawu olusisiseko lwemeko yeliso esiza kuthetha ngalo namhlanje olubizwa ngokuba yi -Aniseikonia (ebizwa ngokuba yi-"an-i-sei-ko-nia"). Ngamafutshane, oku kukungafani phakathi kwamehlo akho amabini ngokubhekiselele kubukhulu okanye ukucaca kwento oyijongileyo.

Kutheni oku kusenzeka? Yintoni (i-Aniseikonia)?

Xa amehlo ethu esebenza kakuhle, oko kukuthi, xa ephilile, umfanekiso wento ebonwa ngamehlo omabini uthunyelwa engqondweni ngokukhulisa okufanayo. Ngaphandle koko, umahluko mncinci kakhulu kangangokuba ingqondo yethu inokuyilungisa. Nangona kunjalo, kumntu one- Aniseikonia , kukho umahluko kwindlela la mehlo mabini akhulisa ngayo izinto. Emva koko, oko iliso elinye likubonayo kunokwahluka ngobukhulu okanye ngesimo kunoko iliso elinye likubonayo. Ngoko ke, oku kuba yingxaki enkulu engqondweni yethu , kuba ulwazi oluvela kumehlo omabini alufani.

Khawucinge nje. Uphakathi, kwaye abantu ababini kwicala lakho ngalinye bakhwaza izinto ezimbini ezahlukeneyo ngaxeshanye. Bekuya kuba nzima kangakanani ukubaqonda bobabini, akunjalo? Usenokuba nentloko ebuhlungu. Yiloo nto eyenzekayo kwi- Aniseikonia , kodwa oku kumalunga namehlo. Amehlo ethu abalulekile kwizinto ezininzi, njengokulinganisela kunye nokulungelelanisa xa uhamba, ngoko ke le meko inokuchaphazela ubomi bakho bemihla ngemihla.

Ngaba kukho iintlobo eziphambili ze (Aniseikonia)?

Ewe, kukho iintlobo ezimbini eziphambili:

1. I-Optical aniseikonia: Oku kubangelwa kukwahluka kwendlela ukukhanya okungena ngayo nokudlula ngayo emehlweni akho. Ngamafutshane, yingxaki kwinkqubo yelensi yeliso.

2. I-aniseikonia ye-retinal: Oku kubangelwa lutshintsho kwi -retina , inxalenye yeliso eyenza umfanekiso esiwubonayo.

Zithini iimpawu ze-Aniseikonia?

Xa amehlo ethu esebenza kakuhle, ingqondo inokudibanisa imiqondiso evela emehlweni omabini ize "idibanise" ukuze yenze umfanekiso omnye ocacileyo. Ukuba kukho umahluko omncinci, ingqondo inokuyilungisa loo ngxaki, ngoko ke ukuba imeko (i-Aniseikonia) ayinzima kakhulu, kusenokungabikho zimpawu. Nangona kunjalo, ukuba umahluko mkhulu, ingqondo ayinakuyilungisa loo ngxaki. Kulapho ke kuvela khona iimpawu.

Ezi zezona mpawu zixhaphakileyo:

• I-Strabismus ligama lezonyango elithetha xa amehlo engajongi kwicala elinye (njengomnqamlezo).
• Ubunzima bokulinganisela kunye nokulungelelanisa: Usenokuziva ngathi uyakhubeka xa uhamba okanye awukwazi ukubamba into kakuhle.
• I-Diplopia: Ukubona izinto ezimbini ngaxeshanye.
• Ukudinwa: Ukuziva ngathi ujikeleza.
• Uxinzelelo lwamehlo okanye ukudinwa kwamehlo (Asthenopia): Amehlo aqala ukuba buhlungu ngokukhawuleza xa efunda incwadi okanye ejonge ikhompyutha.
• Intloko ebuhlungu: Intloko ebuhlungu rhoqo.

Ingakumbi kubantwana abancinci , ingqondo izama ukuziqhelanisa nomahluko ekuboneni phakathi kwamehlo amabini kuba inkqubo yabo yokubona ayikaphuhli ngokupheleleyo. Xa ikwenza oko, iyayeka ukusebenzisa umyalezo ovela kwelinye iliso. Emva koko, iliso elingasetyenziswayo linokuba "liliso elivilaphayo" (i-Amblyopia) . Oku kuthetha ukuba umbono okwelo liso uba buthathaka.

Zithini izizathu ze (Aniseikonia)?

Zininzi izinto ezinokubangela i-aniseikonia. Isenokuba yimeko ekwimehlo akho, into enxulumene nengqondo yakho, okanye isiphumo esibi sonyango. Amanye amayeza anokubangela i-aniseikonia. Ingcali yakho yamehlo, ugqirha wosapho, okanye ikhemisti ngumntu ongcono onokuthetha naye ngale nto.

Izizathu eziphambili zingahlulwahlulwa zibe ziindidi ezininzi:

Utshintsho lwamehlo kwindlela ukukhanya okuhamba ngayo ngelihlo

I-Aniseikonia inokubangelwa zizinto ezichaphazela indlela ukukhanya okudlula ngayo emehlweni akho ukuya kwi-retina yakho. Imizekelo:

• I-Anisometropia: Ubukhali bokubona beliso elinye bahluke kakhulu kobo belinye iliso.
• Izifo ze-corneal: Ingakumbi iimeko eziguqula imo ye-cornea (Keratoconus) . I-cornea yi-membrane ecacileyo engaphambili kweliso.
• Imeko yelensi: Iicataracts kwiliso elinye kuphela, okanye ilensi yeliso isusiwe (iAphakia) .
• Ukulimala kwamehlo: Ukonakala kwe-cornea, ilensi, okanye ezinye iindawo zeliso, okubangela ukuba zitshintshe imo.
• Ezinye iingxaki zezicubu ezidityanisiweyo: Umzekelo, iimeko ezifana neMarfan syndrome okanye i-Ehlers-Danlos syndrome .

Utshintsho lwe-retina

I-Aniseikonia inokubangelwa zizifo ezinxulumene ne-retina ezifana nezi:

• I-Macular pucker: I-macula yinxalenye ye-retina enika umbono ocacileyo.
• Umonakalo we-retina: Ukukrazuka okanye ukuqhekeka kwe-retina .
• Iimeko ezibeka uxinzelelo kwi-retina nakwi-optic nerve: Umzekelo , i-glaucoma .
• Iimeko ezifana ne (Central serous retinopathy) .
• I-retinopathy enxulumene nesifo seswekile .
• Iimeko ezinje (Ukuwohloka kwe-macular okunxulumene nobudala obumanzi - i-Wet AMD) .

Iinkqubo zokujonga

Ezinye iindlela zonyango zinokubangela i-aniseikonia:

• Utyando lokulungisa umbono nge-laser: utyando olufana ne- (LASIK) , (Photorefractive Keratotomy - PRK) okanye (Small Incision Lenticule Extraction - SMILE) .
• Ukutshintsha ilensi yeliso ngelensi yokwenziwa (Intraocular lens - IOL). Oku kudla ngokwenziwa ngexesha lotyando lwe-cataract.
• Utyando olufana ne -vitrectomy okanye i-scleral buckle , oluthatha indawo ye-vitreous humor nge-silicone oil okanye i-gas bubble ukuze kugcinwe imo yeliso de iliso liphole.

Iphathwa njani i-Aniseikonia?

Unyango lwe-aniseikonia luyahluka ngokuxhomekeke kuhlobo onalo.

• I-aniseikonia yokujonga: Oku kunyangwa kakhulu ngeeglasi zamehlo okanye iilensi zokunxibelelana . Ngamanye amaxesha, utyando lokulungisa umbono lunokubonelela ngoncedo.
• I-aniseikonia ye-retinal: Oku kunzima ngakumbi ukunyanga. Unyango oluqhelekileyo kunyango lwesizathu esiyintloko, ukuba kunokwenzeka. Ungasebenzisa neeglasi ezinohlobo olukhethekileyo lwelensi ebizwa ngokuba yi-iseikonic lens . Ezi lensi zisebenza ngokulinganisela ukukhulisa imifanekiso oyibonayo emehlweni omabini.

Khawucinge nje, ukuba akukho nanye kwezi ndlela zonyango isebenzayo, okanye ukuba kukho imeko apho zingenakukwenziwa khona, indlela yokugqibela yindlela ebizwa ngokuba yi- "occlusion" . Oko kukuthi, iliso elinye ligqunywe ngokupheleleyo nge-patch. Emva koko ingqondo ayinyanzelekanga ukuba icubungule ezo miyalezo zimbini zikhuphisanayo. Ngethamsanqa, kwiimeko ezininzi, oku akufuneki.

Injani imeko (i-Aniseikonia)? Ingaba iyingozi?

I-Aniseikonia ayisoloko iyingozi ebomini. Nangona kunjalo, inokuba yinto ecaphukisayo kwaye inokuphazamisana nemisebenzi yemihla ngemihla.
