Pigmentary dispersion syndrome (PDS) ke bothata bo atisang ho fumanoa nakong ea tlhahlobo ea mahlo kamehla . PDS e etsahala ha pigment ho tloha ka morao ho iris , karolo e mebala ea leihlo la hao, butle-butle e lokolloa ka har'a metsi a ka hare a tletseng karolo e ka pele ea leihlo. Mokelikeli ona, o bitsoang aqueous humor, o tsamaisa pigment ka tsela e pota-potileng ka lehlakoreng le ka pele la leihlo le ho ea ka mokokotlo oa leihlo, o bitsoang meshwork ea trabecular.
Haeba ho lokolloa pigment e lekaneng, e ka qala ho koala mokoallo ona oa metsi 'me o thibela hore metsi a se ke a phalla hantle. Ha sena se etsahala, khatello ka har'a leihlo e ka 'na ea haha le ho baka glaucoma ea pigment.
Matšoao
Matšoao a PDS a ka 'na a bakoa ke ho eketseha ka tšohanyetso ha khatello ea mahlo. Boemo bo ka baka likarolo tsa matšoao, ho kenyelletsa tse latelang:
- Pono e fosahetseng
- Li-halos tse pota-potileng mabone
- Bohloko bo botle ba mahlo
Lintho Tse Kotsing
Ha motho leha e le ofe a ka hlahisa PDS, ho bonahala eka ho tloaelehile haholo ho banna ba bacha, ba basoeu ba pakeng tsa lilemo tse 20-40. Ho thahasellisang ke hore batho ba bangata ba hlahisang PDS ba le haufi le ho bona.
Lisosa
PDS e bakoa ke pigment e feteletseng e pota-potileng ka leihlo e lokolitsoeng ka morao ho iris. Batho ba bang ba na le li-anatomy tsa mahlo tse ikhethang tse etsang hore lense e hlajoe ke lense ho itšilafatsa ka ntle ho iris. Lens la li-lens li na le likhoele tse tšesaane tse tšoereng lense ea kristalline ea leihlo sebakeng se ka morao ho iris.
Ha li-iris le lens li fetoha sebōpeho, likhahla li tsosoa khahlanong le iris 'me li-pigment li qala ho fokotseha.
Tsejoa
Hobane pigment e ntse e pota-potile, e kenngoa ka morao kahare ea cornea ka mokhoa o ts'oanang. Ha motho a hlokometse mahlo, sena se bitsoa "Krukenberg's Spindle." Kaha lefu lena le tsoa karolong e ka morao ea iris, ngaka e ka boela ea bona "transillumination ea iris." Seo se bolela hore ngaka e bona bokooa bo kang ba marang-rang ho iris moo khanya e fetang ka lebaka la ho haella ha pigment.
Ka ho sebelisa li-gonioscopy, a ka bona ponahalo e feteletseng e kenngoa mokokotlong oa leihlo. Khatello ea mahlo e ka 'na ea se ke ea phahama kapa e ke ke ea phahama. Haeba mokuli a entse li-glaucoma tse nang le pigment, joale lipontšo tsa glaucoma li ka boela tsa bonoa.
Seo U Lokelang ho se Tseba
Ho bohlokoa ho hlokomela hore batho bohle ba nang le PDS ba ke ke ba hlahisa pigmentary glaucoma. Khatello ea mahlo e ka fetoloa ka ho pharaletseng ho bakuli ba nang le PDS kapa pigmentary glaucoma. Ke batho ba 30% feela ba nang le PDS ba tla hlahisa pigmentary glaucoma. U se ke ua hlolloa haeba ngaka ea hao e u botsa ka mekhoa ea hau ea boikoetliso. Matšoao a PDS a bonahala a feta haholo nakong ea boikoetliso. Ho nahanoa hore mofuthu o matla oa ho ikoetlisa o ka lokolla likolobe tse ngata. Ha ho fanoa ka pigment e eketsehileng, khatello ea mahlo e ka phahama 'me ea baka matšoao a amanang.
Ntho e molemo ka ho fetisisa eo u ka e etsang ke ho khutlela litekong selemo le selemo kapa ka makhetlo a mangata joalo ka tataiso ea ngaka ea hau. Pigmentary glaucoma, ho fapana le e tloaelehileng "open angle glaucoma," e lokela ho fumanoa kapele 'me e tšoaroe ka mabifi.
