“Marka retina-du gaarto ora serrata, maxay yihiin isbeddellada anatomy-ga ee halkaas ka dhacaya?”

 Waxaad maskaxda ku haysaa in ora serrata ay tahay xadka u dhexeeya retina-da iyo ciliary body.

Maxaa halkaas ka dhacaya?

1. Neural retina ends
→ Qaybta shaqaysa ee retina-da ee loo yaqaan neural retina halkaas ayay ku dhammaanaysaa.

2. RPE continues
→ Lakabka RPE (retinal pigment epithelium) ma dhammaanayo; wuxuu sii socdaa isagoo noqonaya pigmented ciliary epithelium.

3. Neural retina continues as non-pigmented ciliary epithelium
→ Halkan qoraalkaaga waxaa muhiim ah in si sax ah loo fahmo: qaybta hore ee retina-da waxay u gudubtaa epithelium-ka ciliary body, oo loo kala yaqaan non-pigmented ciliary epithelium.

4. Pars plana
→ Ciliary body-ga qaybtiisa fidsan waxaa la yiraahdaa pars plana; waxay ku taallaa anterior-ka ora serrata.

5. Vitreous base
→ Vitreous base si aad ah ayuu ugu dheggan yahay aagga ora serrata.

6. Clinical
→ Maadaama vitreous-ku si xoog leh ugu xiran yahay halkaas, retinal tears iyo retinal dialysis ayaa ka dhici kara agagaarka ora serrata.

Hal jumlad oo aad ku xafidi karto:

Ora serrata = meesha neural retina ku dhammaato, retina/RPE-na ay ugu gudbaan ciliary epithelium, iyadoo vitreous base-ku si xoog leh ugu dheggan yahay.
