Qhov sib txawv tseem ceeb ntawm kev loj hlob thiab tsis muaj kev loj hlob retinopathy yog qhov kev loj hlob ntawm retinopathy yog hais txog qhov muaj cov kab mob neovascularization (kev loj hlob ntawm cov hlab ntsha txawv txav) hauv cov retina hauv ntshav qab zib retinopathy, thaum tsis muaj ntshav qab zib retinopathy yog hais txog kev mob ntshav qab zib retinopathy thaum ntxov tsis muaj neovascularisation.
Cov theem tom qab ntawm mob ntshav qab zib retinopathy yog hu ua proliferative diabetic retinopathy (PDR). Nyob rau theem no, cov hlab ntsha txawv txav thiab cov caws pliav loj tuaj ntawm qhov chaw ntawm retina. Lawv txuas rau sab nraub qaum ntawm lub vitreous, uas yog cov khoom zoo li jelly uas ua rau qhov chaw ntawm lub qhov muag. Lub vitreous ces rub rau ntawm daim tawv nqaij caws pliav, thiab ua rau cov hlab ntsha los ntshav mus rau hauv cov kab noj hniav vitreous. Qhov xwm txheej no hu ua vitreous hemorrhage. Qhov no yuav tshwm sim ntau zaus hauv kev mob ntshav qab zib retinopathy thiab thaum kawg tuaj yeem ua rau qhov muag tsis pom kev sai. Tab sis feem ntau, cov hemorrhages yuav tshem tawm ntawm lawv tus kheej. Feem ntau thiab ntxov tshaj plaws ntawm ntshav qab zib retinopathy yog hu ua non-proliferative ntshav qab zib retinopathy (NPDR). Nyob rau theem pib ntawm ntshav qab zib retinopathy cuam tshuam nrog edema thiab tawm ntawm cov exudates nyuaj los ntawm cov hlab ntsha txawv txav hauv nruab nrab retina, uas thaum kawg ua rau qhov muag tsis pom hauv nruab nrab. Tom qab ntawd, ntxiv kev txwv ntawm cov ntshav mus rau retina (vascular occlusion) tshwm sim, nrog rau kev nce hauv macular edema.
YYam Proliferative Retinopathy yog dab tsi?
Daim ntawv hnyav dua ntawm ntshav qab zib retinopathy yog hu ua proliferative diabetic retinopathy. Hauv hom retinopathy no, cov hlab ntsha puas tsuaj kaw. Qhov no ua rau muaj qhov txawv txav ntawm cov hlab ntsha tshiab hauv retina. Cov hlab ntsha txawv txav no nkag mus rau hauv lub vitreous, uas yog cov khoom zoo li jelly uas ua rau hauv nruab nrab ntawm lub qhov muag.
Daim duab 01: Proliferative Retinopathy
Thaum kawg, cov caws pliav tau txhawb nqa los ntawm kev loj hlob ntawm cov hlab ntsha tshiab txawv txav ua rau lub retina tshem tawm ntawm lub qhov muag tom qab. Cov hlab ntsha tshiab kuj tseem tuaj yeem cuam tshuam cov kua dej tawm ntawm qhov muag. Yog li ntawd, lub siab nyob rau hauv lub qhov muag yuav nce. Qhov no tuaj yeem ua rau cov paj hlwb uas nqa cov duab ntawm lub qhov muag mus rau lub hlwb, ua rau glaucoma. Kev kho mob ntshav qab zib retinopathy yog kev kho mob laser, txhaj tshuaj qhov muag, thiab phais qhov muag.
YNonproliferative Retinopathy yog dab tsi?
Nonproliferative retinopathy yav dhau los hu ua keeb kwm yav dhau retinopathy. Nws yog qhov ntxov tshaj plaws ntawm ntshav qab zib retinopathy. Hauv nonproliferative retinopathy, microscopic hloov pauv tshwm sim hauv cov hlab ntsha ntawm lub qhov muag. Txawm li cas los xij, cov kev hloov no tsis tsim cov tsos mob. Cov kab mob nonproliferative nce los ntawm me me mus rau theem hnyav.
Daim duab 02: Nonproliferative Retinopathy
Nonproliferative mob ntshav qab zib retinopathy yog pib tshwm sim los ntawm microaneurysms. Microaneurysm yog tus cwj pwm los ntawm cov ntshav txhaws hauv cov hlab ntsha phab ntsa. Cov pob liab liab no tuaj yeem tawg thiab xau rau hauv retina. Cov pob me me uas muaj cov ntshav tuaj yeem sau rau hauv retina. Tab sis lawv tsis tsim cov tsos mob tshwm sim thaum ntxov ntawm tus kab mob. Tom qab ntawd, nyuaj exudates tsub zuj zuj nyob rau hauv nruab nrab retina, abnormality nyob rau hauv kev loj hlob ntawm microscopic hlab ntsha nyob rau hauv lub retina, thiab los ntshav los ntawm cov hlab ntsha yuav tshwm sim. Kev saib xyuas tsis tu ncua yog kev kho mob rau cov ntshav qab zib retinopathy uas tsis yog proliferative. Txawm li cas los xij, ua raws li kws kho mob cov lus qhia txog kev noj zaub mov, kev tawm dag zog, thiab tswj cov ntshav qab zib tuaj yeem txhim kho qhov xwm txheej.
Dab tsi yog qhov zoo sib xws ntawm Proliferative thiab Nonproliferative Retinopathy?
- Ob leeg yog theem ntawm ntshav qab zib retinopathy.
- Lawv ua rau kev puas tsuaj rau lub retina.
- Ob leeg yuav ua rau qhov muag tsis pom kev.
Qhov txawv ntawm Proliferative thiab Nonproliferative Retinopathy yog dab tsi?
Proliferative retinopathy yog hais txog qhov muaj ntawm neovascularization (kev loj hlob ntawm cov hlab ntsha txawv txav) hauv retina tom qab theem ntawm ntshav qab zib retinopathy. Ntawm qhov tod tes, kab mob ntshav qab zib retinopathy thaum ntxov tsis muaj neovascularization hu ua nonproliferative ntshav qab zib retinopathy. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev loj hlob thiab nonproliferative retinopathy. Ntxiv mus, proliferative retinopathy yog tus cwj pwm los ntawm cov tsos mob hnyav xws li kev loj hlob ntawm cov hlab ntsha tshiab txawv txav thiab glaucoma. Meanwhile, nyob rau hauv nonproliferative retinopathy, microscopic pauv tshwm sim nyob rau hauv cov hlab ntsha ntawm lub qhov muag. Tab sis cov kev hloov no tsis tsim cov tsos mob. Yog li, qhov no kuj yog qhov sib txawv ntawm kev loj hlob thiab tsis muaj kev loj hlob retinopathy.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev loj hlob thiab tsis muaj kev loj hlob retinopathy nyob rau hauv daim ntawv tabular.
Summary – Proliferative vs Nonproliferative Retinopathy
Proliferative thiab nonproliferative retinopathy yog theem ntawm ntshav qab zib retinopathy. Proliferative retinopathy yog hais txog qhov muaj ntawm neovascularization (kev loj hlob ntawm cov hlab ntsha txawv txav) hauv retina nyob rau theem tom qab ntawm ntshav qab zib retinopathy. Thaum ntxov mob ntshav qab zib retinopathy kab mob tsis muaj neovascularization hu ua nonproliferative ntshav qab zib retinopathy. Ob qho tib si yuav ua rau pom kev tsis pom kev yog tias lawv tsis raug tswj kom raug. Yog li, qhov no qhia txog qhov sib txawv ntawm kev loj hlob thiab tsis muaj kev loj hlob retinopathy.
