Progressive Retinal Atrophy in Dogs yog ib yam kab mob uas tshwm sim hauv ntau hom dev. Nws lub hauv paus chiv keeb yog keeb kwm yav dhau los thiab nyiam pib thiab pom cov tsos mob thaum cov dev twb laus lawm. Txawm li cas los xij, qee zaum cov tsos mob tshwm sim thaum tseem hluas.

Nov yog kab mob degenerative thiab tsis muaj tshuaj kho. Vim li no, nws yog ib qho tseem ceeb heev uas yuav tsum tau ua tib zoo saib xyuas cov tsos mob thawj zaug kom tus kws kho tsiaj ncua kev dig muag tag nrho ntawm tus dev kom ntau li ntau tau. Nyob rau hauv tsab xov xwm no ntawm peb lub xaib koj tuaj yeem paub cov ntaub ntawv tseem ceeb tshaj plaws txog dab tsi yog qhov kev loj hlob ntawm retinal atrophy hauv dev, nws cov tsos mob thiab kev kho mob

Dab's retina

retina yog lub qhov muag lub luag haujlwm rau ntes thiab xa cov duabntes los ntawm cov hlab ntsha ntawm lub paj hlwb mus rau lub hlwb. Lub hlwb txiav txim siab rau lawv thiab muab lawv lub ntsiab lus tseem ceeb rau peb. Muaj photoreceptors nyob rau hauv lub retina. Lawv yog cov hlwb uas nws txoj haujlwm yog los ntes lub teeb, xim thiab cov duab.

Ob hom yog txawv:

  • Cones: cov no yog cov hlwb uas ua rau pom kev pom thaum nruab hnub. Lawv xav tau ntau lub teeb. Lawv txawv cov xim ntawm ib leeg. Lawv yog lub luag hauj lwm rau lub zeem muag zoo.
  • Rods: Cov hlwb no xav tau lub teeb me ntsis vim lawv nkag siab zoo heev. Lawv muaj lub luag haujlwm rau kev pom kev hmo ntuj.

Koj puas xav nyeem cov lus hauv qab no ntawm Cov dev pom li cas? ntawm peb qhov chaw.

Cov kab mob retinal atrophy hauv dev yog dab tsi?

Progressive retinal atrophy in dogs is a degenerative disease uas cuam tshuam rau peb cov tsiaj (feem ntau yog dev thiab miv). Nws kuj tuaj yeem cuam tshuam ntau lwm yam tsiaj. Nyob ntawm cov photoreceptors uas cuam tshuam ua ntej, peb tuaj yeem xav txog:

  • Sticks: Dogs poob lawv qhov pom kev hmo ntuj. Nws hu ua nyctalopia txawm hais tias peb tuaj yeem hnov mob qhov muag tsis pom hauv dev.
  • Cones: dev poob lawv qhov muag pom kev nruab hnub. Nws hu ua hemeralopia.
  • Pob tib lub sij hawm: dev tsis pom kev tsis cuam tshuam qhov kaj.

Nws nyob ntawm cov tsiaj yug tsiaj uas ib tug los yog lwm yam receptor cuam tshuam; nrog rau lub hnub nyoog uas cov tsos mob ntawm kev mob retinal atrophy, kev kho mob hu ua PRA, tau tshwm sim. Cov tsos mob tshwm sim maj mam thiab zuj zus.

Vim koj twb paub lawm tias qhov mob retina atrophy hauv dev yog dab tsi, peb yuav pom nws cov tsos mob li cas hauv qab no.

Symptoms of PRA or Progressive Retinal Atrophy in Dogs

Cov tsos mob tshwm sim feem ntau ntawm kev mob retinal atrophy hauv dev yog raws li hauv qab no:

  • Visual Loss: Cov rods feem ntau yog thawj cov duab receptors cuam tshuam, ua rau nyctalopia (hmo ntuj dig muag hauv dev). Tom qab ntawd, hemeralopia (hnub dig muag) tshwm. Kev ua haujlwm tsis zoo ntawm ib lossis lwm cov duab thaij duab sib txawv nyob ntawm cov haiv neeg thiab hom atrophy. Ib qho kev mob tshwm sim yog qhov nyuaj pom cov khoom txav. Kev dig muag tag tsis tuaj yeem kwv yees tau; tab sis tus me nyuam tus dev uas muaj tsos mob, tus kab mob yuav loj zuj zus.
  • Dilated Pupils: Lawv tsis teb zoo rau lub teeb. Cov dev muaj xim ntsuab, daj lossis txiv kab ntxwv nyob rau hauv lawv cov menyuam kawm ntawv, tshwm sim los ntawm retinal hyperreflexia (qhov ci siab tshaj li qub) thiab mydriasis(qhia tus menyuam kawm ntawv). Yog xav paub ntxiv txog cov menyuam kawm ntawv dilated hauv dev: ua rau thiab kev kho mob, tsis txhob yig mus sab laj tus ncej uas peb pom zoo.
  • Cataracts: lawv tshwm sim vim cov retinal degeneration. Nws yog qhov tshwm sim thib ob ntawm qhov muag puas. Cataracts yog tshwm sim los ntawm kev tso tawm ntawm cov khoom tsim los ntawm lub retina puas.

Diagnosis of retinal atrophy in dogs

Kev kuaj mob yuav tsum tau lees paub los ntawm kws kho tsiaj. Nws yog qhov zoo tshaj los ua kuaj qhov muag txhua xyoo nyob rau hauv cov tsiaj uas muaj tus kab mob no.

Cov tswv yim siv rau kev kuaj mob ntawm retinal atrophy hauv dev yog:

  • Ophthalmoscopy: saib ntawm lub qhov muag.
  • Electrorrenitography: Siv electrodes, cov lus teb ntawm photoreceptors rau ntau hom teeb yog ntsuas. Nws yog txoj hauv kev zoo tshaj plaws ntawm kev kuaj mob APR.

kev kho rau kev nce qib retinal autrophy in devs

PRA los yog kev mob ntshav qab zib atrophy hauv dev tsis muaj kev kho zooNws tuaj yeem txo qis los ntawm kev noj cov tshuaj antioxidants thiab cov vitamins tsis tu ncua. Txawm li cas los xij, ua tus kab mob degenerative, qhov muag tsis pom kev yog qhov kawg. Yog tias cov kab mob cataracts tshwm sim, qee zaum lawv yuav tsum tau phais, txawm hais tias nws tsis tuaj yeem tiv thaiv kev txuas ntxiv ntawm APR.

Lub sijhawm uas qhov kev ua haujlwm no yog qhov tsim nyog rau kev ua kom lub ntsej muag atrophy hauv dev yog cov hauv qab no:

  • Uveitis: lens dependent.
  • Glaucoma: lens dependent.

Txoj kev cuam tshuam yuav tsum ua kom tsis txhob muaj kev cuam tshuam thib ob los ntawm cov kab mob cataracts.

Tiv thaiv kom tsis txhob mob ntshav qab zib hauv cov dev

Txoj kev tiv thaiv zoo tshaj plaws tiv thaiv PRA los yog kev loj hlob ntawm retinal atrophy nyob rau hauv cov dev yog lees paub los ntawm puppyhood tias lawv tsis muaj tus kab mob no. Qhov no ua tiav los ntawm kev txais yuav cov dev nrog daim ntawv pov thawj ophthalmological certificate pub dawb ntawm ocular pathology ntawm lawv niam lawv txiv Hauv nws qhov tsis muaj APR hauv cov niam txiv kab ntawm tuaj yeem. Muaj ntau hom tsiaj uas yuav tsum muaj daim ntawv pov thawj no rau kev yug me nyuam.

Cov neeg uas xav tau daim ntawv pov thawj no yuav tsum xa lawv tus dev mus rau qhov kev xeem hauv qab no:

  • Electorretinography (ERG).
  • Ophthalmoscopy.
  • Eye ultrasound.

Tam sim no, cov dev sib xyaws lossis cov uas tsis paub cov niam txiv yuav tsum mus ntsib lawv tus kws kho tsiaj tsawg kawg txhua 6-12 lub hlis txhawm rau tiv thaiv qhov teeb meem no thiab kuaj pom sai li sai tau.
