I-Congenital glaucoma yisifo esingajwayelekile samehlo esithinta izingane kusukela ekuzalweni kuya eminyakeni emithathu ubudala, esibangelwa ingcindezi eyandayo ngaphakathi esweni ngenxa yokuqoqwa koketshezi, okungathinta imizwa ye-optic futhi kuholele ekuphuphuthekeni lapho kungalashwa.

Ingane ezalwa ine-congenital glaucoma inezimpawu ezifana ne-cornea enamafu futhi evuvukile namehlo akhulisiwe. Ezindaweni lapho kungavivinywa khona iso, kuvame ukutholakala kuphela ezinyangeni eziyi-6 noma kamuva, okwenza kube nzima enganeni ukuthi ithole ukwelashwa okungcono kakhulu nokubikezela okubonakalayo.

Ngalesi sizathu, kubalulekile ukuthi umntwana osanda kuzalwa enze ukuhlolwa kwamehlo ngudokotela wezifo zamehlo kuze kube sekupheleni kwe-trimester yokuqala. Uma kwenzeka kuqinisekiswa i-Congenital Glaucoma, udokotela wamehlo angahle anikeze nokwehla kwamehlo ukunciphisa ingcindezi ye-intraocular, kepha lokhu kwenziwa ukunciphisa ingcindezi ngaphambi kokuhlinzwa. Ukwelashwa kuqukethe ukuhlinzekwa nge-goniotomy, trabeculotomy noma okufakelwa kwamalungu okufakelwa okukhipha uketshezi lwe-intraocular.

Ungayelapha kanjani i-glaucoma ezalwa nayo

Ukwelapha iCongenital Glaucoma, udokotela wezifo zamehlo anganikeza amaconsi wamehlo ukwehlisa ingcindezi ye-intraocular yokwehlisa ingcindezi ngaphambi kokuhlinzwa. Ukuhlinzwa kwenziwa nge-goniotomy, trabeculotomy noma ukufakelwa kwamalungu okufakelwa okukhipha uketshezi lwe-intraocular.

Kubalulekile ukwenza ukuxilongwa kusenesikhathi bese uqala ukwelashwa, njengoba kungenzeka ukuvimbela izinkinga, njengokungaboni. Yazi amaconsi asemqoka okwelapha i-glaucoma.

Izimpawu ze-glaucoma yokuzalwa

I-glaucoma ezalwa nayo ingabonakala ngezinye zezimpawu ezifana nalezi:

• Kuze kube unyaka ongu-1: I-cornea yeso iyavuvukala, iba namafu, ingane ikhombisa ukungakhululeki ekukhanyeni bese izama ukumboza amehlo ekukhanyeni;
• Phakathi kweminyaka engu-1 no-3: I-cornea inyuka ngosayizi futhi kujwayelekile ukuthi izingane zinconywe ngamehlo azo amakhulu;
• Kuze kube yiminyaka emithathu: Izimpawu nezimpawu ezifanayo. Amehlo azokhula kuphela ngokwandisa ingcindezi kuze kube yile minyaka.

Ezinye izimpawu ezinjengokukhipha ngokweqile izinyembezi namehlo abomvu nazo zingaba khona ku-glaucoma yokuzalwa.

Ukuxilongwa kwe-glaucoma engokwemvelo

Ukuxilongwa kwangaphambi kwesikhathi kwe-glaucoma kuyinkimbinkimbi, njengoba izimpawu zibhekwa njengokungaqondile futhi zingahluka ngokuya ngeminyaka lapho kuqala khona izimpawu nezinga lokukhubazeka. Kodwa-ke, i-congenital glaucoma ingabonakala ngokuhlolwa okuphelele kwamehlo okubandakanya ukukala ingcindezi ngaphakathi kweso nokuhlola zonke izingxenye zeso ezifana ne-cornea ne-optic nerve, ngokwesibonelo. Funda kabanzi mayelana nokuhlolwa kwe-glaucoma.

Ngokuvamile, i-glaucoma ibangelwa ingcindezi eyandayo emehlweni, eyaziwa ngokuthi ingcindezi ye-intraocular. Ukwanda kwengcindezi kwenzeka ngoba uketshezi olubizwa ngokuthi yi-aqueous humor lukhiqizwa esweni futhi, njengoba iso livaliwe, lolu ketshezi ludinga ukukhishwa ngokwemvelo. Lapho uhlelo lwamanzi olungasebenzi lungasebenzi kahle, uketshezi alunakukhishwa esweni ngakho-ke ingcindezi engaphakathi kweso iyakhula.

Kodwa-ke, yize ukwanda kwengcindezi kuyimbangela ejwayelekile kunazo zonke, kunezimo lapho kungekho khona ingcindezi ephezulu ye-intraocular futhi, kulezi zimo, lesi sifo sibangelwa ukungasebenzi kahle kwemithambo yegazi ye-optic nerve, ngokwesibonelo.
