I-Pigmentary dispersion syndrome (i-PDS) yisifo esivame ukutholakala ngesikhathi sokuhlolwa kweso njalo . I-PDS ivela lapho i-pigment evela ngemuva kwe- iris , ingxenye enemibala yeso lakho, ikhishwa kancane kancane emzimbeni wangaphakathi ogcwalisa ingxenye yangaphambili yeso. Leli gesi, elibizwa ngokuthi i-humorous humor, lithwala i-pigment ngendlela ehamba phambili ngeso lengxenyana yangaphambili yeso futhi lingena emgodini we-drain eye, okuthiwa i-meshwork engathandeki.
Uma kukhishwa i-pigment eyanele, ingaqala ukuvula le ngxube yomsele futhi igweme uketshezi ukuphuma kahle. Uma lokhu kwenzeka, ingcindezi ngaphakathi kweso ingakha futhi ibangele i-glaucoma yezingulube.
Izimpawu
Izimpawu ze-PDS cishe zibangelwa ukwanda okungazelelwe kokucindezela kweso. Lesi simo singabangela iziqephu zezimpawu, kuhlanganise okulandelayo:
- Umbono ophundlekile
- Ama-halos enombala azungeze izibani
- Ubuhlungu obukhulu bomzimba
Izingozi Zezingozi
Ngesikhathi noma ubani engakwazi ukuthuthukisa i-PDS, kubonakala sengathi ivame kakhulu kubantu abancane, abesilisa abamhlophe phakathi kweminyaka engama-20-40. Ngokuthakazelisayo, iningi labantu abathuthukisa i-PDS bayasondela.
Izimbangela
I-PDS ibangelwa i-pigment eyengeziwe ehambayo ezungeze iso elikhishwe ngemuva kwe-iris. Abanye abantu banesifo esithile esiyingqayizivele esenza ukuthi i-lens zonules igubhe ngokuxubha ngemuva kwe-iris. I-lens zonules yizintambo ezincane ezibamba i-lens crystalline yeso endaweni esele ngemuva kwe-iris.
Njengoba iris ne-lens zishintsha ukuma, iziklamo zihlasela ngokumelene ne-iris futhi i-pigment iqala ukuphuma.
Ukuxilongwa
Ngenxa yokuthi i-pigment iyazungezile, ithola endaweni yangasese ye- cornea iphethini eliqondile. Ekunakekelweni kwamehlo, lokhu kuthungwa kwe-pigmentary kwaziwa ngokuthi "i-Spindle kaKrukenberg." Ngenxa yokuthi le ngulube ivela ngemuva kwe-iris, udokotela angabona futhi "ukudluliselwa kwe-iris." Lokho kusho ukuthi udokotela ubona amaphutha afana nokuqhafaza e-iris lapho ukukhanya kudlula khona ngenxa yokuntuleka kwe-pigment.
Ngokusebenzisa i-gonioscopy, angayibona ingulube eyengeziwe efaka umsele we-eye. Ukucindezeleka kweso kungase kuphakanyiswe noma kungenakuphakanyiswa. Uma isiguli senze i-glaucoma ye-pigmentary, izimpawu ze- glaucoma nazo zingabonakala.
Okunye Okufanele Ukwazi
Kubalulekile ukuqaphela ukuthi bonke abantu abane PDS ngeke bahlakulele i-glaucoma yezingulube. Ukucindezeleka kweso kungashintsha kabanzi kubantu abanezidakamizwa ze-PDS noma i-glaucoma yezingulube. Abantu abangaba ngu-30 kuphela abane-PDS bazothuthukisa i-glaucoma ye-pigmentary. Ungamangali uma udokotela wakho ekubuza ngemikhuba yakho yokuzivocavoca. Izimpawu ze-PDS zibonakala zenzeka ngaphezulu ngesikhathi sokuzivocavoca. Kucatshangwa ukuthi ukunyakaza okukhulu kokuzivocavoca kungadala ukukhululwa kwezingulube. Uma kukhishwa ukugquma okuningi, ukucindezeleka kweso kungakhula futhi kubangele izimpawu ezihambisanayo.
Into engcono kakhulu ongayenza ukubuyisela izivivinyo minyaka yonke noma ngaphezulu njengoba kuqondiswa udokotela wakho. I-glaucoma ye-pigmentary, ngokungafani ne-"evelele i-glaucoma evulekile," kufanele ifakwe ngokushesha futhi iphathwe kabi.
