Txawm li cas los xij, thaum muaj kev hloov pauv hauv cov metabolism hauv lub lens, qhov opacity pom hauv lub lens uas yog hu ua cataract.

Cov kab mob cataracts tau muab faib ua ntau yam:

  • Vim lub hnub nyoog uas lawv tshwm sim: lawv muaj peev xwm xeeb tub (yog tias tus tsiaj yug los nrog lawv), cov menyuam yaus lossis hnub nyoog laus.
  • Depending on maturity or evolutionary stage: they can be incipient, immature, mature or hypermature.
  • Nyob ntawm lawv cov laj thawj: lawv tuaj yeem ua tau los ntawm noob neej, metabolic, post-inflammatory, thiab lwm yam.
  • Nyob ntawm qhov chaw: lawv tuaj yeem ua rau lub ntsej muag lossis lub ntsej muag tom qab, nuclear, posterior cortical, equatorial lossis axial cataracts.

Nyob ntawm lawv qhov txuas ntxiv thiab qib ntawm kev loj hlob, kab mob cataracts tuaj yeem ua rau , yog li lawv sawv cev rau kev puas tsuaj loj rau cov cov tsiaj uas raug kev txom nyem los ntawm lawv.

  • Uveitis: nthuav tawm nrog blepharospasm (kaw qhov muag), hyperemia (qhov muag liab), lacrimation, miosis (pupillary contraction), opacity ntawm lub cornea, suav nrog hyphema (cov ntshav tso rau hauv lub anterior chamber) los yog hypopyon (tej cov qe ntshav dawb nyob rau hauv lub anterior chamber).
  • Glaucoma: tshwm sim nrog qhov muag mob, buphthalmia (nce qhov muag loj), pob txha opacity, mydriasis (cov menyuam kawm ntawv dilation) thiab tsis pom kev.
  • Lens dislocation: nthuav tawm nrog qhov muag mob, tearing, blepharospasm (kaw qhov muag), aphakic crescent (moon-shaped silhouette) thiab txawv txav txav ntawm iris thiab lens.

Cov larva nkag mus rau lub lens thaum nws tab tom tsim thiab ua rau cataract tsim. Nyob rau hauv cov ntaub ntawv no, ob lub qhov muag feem ntau cuam tshuam, uas yog, ob tog cataracts tshwm sim.
  • Hereditary cause: tshwj xeeb tshaj yog nyob rau hauv consanguinity los yog inbreeding, vim kev hla ntawm cov neeg muaj feem xyuam. Vim li no, cataracts nyob rau hauv dwarf luav, thiab lwm yam breeds, yog ib qho tshwm sim thaum lawv los ntawm lub luag hauj lwm breeders. Nws yog ib qho tseem ceeb tsis txhob txhawb qhov no thiab xaiv qhov kev saws me nyuam.
