bleb dystrophy

[paj200]

could anyone on here explain in detail what" bleb dystrophy" is?
i have been told that i have this very rare condition in both eyes.
i am a patent at the Morfield eye hospital in london. They want to
scrap off the surface of both eyes' what are the risk involved.
Is there anyone that could shed some light on this.

thank you

No you're totally wrong. The conversation thread is on a variety of basement membrane disorder which a disease of the superifical cornea.

you are talking about a glaucoma filtering bleb which is a blister like area where a glaucoma operation has made a hole into the eye to drain the aqueious to outside the eye under the conjunctiva. Google the term to see what it looks like "Glaucoma filtering bleb"

In simple terms the "bleb" is sort of an overlap right at the border between the white and transparent parts of the cornea.   This overlap allows for internal eye pressure release.  If the bleb gets clogged (they call it "narrow angle glaucoma") the liquid cannot drain out and the pressure builds up.
If I am wrong pllease forgive me and correct me!
Thanks.  Mike

Low risk: infection, bleeding, scarring, damage to vision.
Medium risk: areas slough off in other places and your problem continues.

Next step if often with eximer laser take entire surface of cornea off, wear bandage soft contact lens while it heals.

Even with scaping being successful you likely will need to use drops and ointments at bedtime.

Thank you for you reply & link,
very interesting. could you tell
me what the risks are when having
the surface of your eyes craped?

Here's a reference. It's a variation of superficial basement membranes syndromes and differentiated on the basis of the material in the basement membrane.

You can read the many posts here about basememt membrane disorder and recurrent corneal erosion and assume that bleb dystrophy will behave the same.

i take it that eyes are your field!! This condition is very rare' but i would have thought that you would have heard of it, it can someimes be mistaken for karatoconus.

thanks for the help!!

Doesn't ring any bells. Ask your Eye MDs for clarification.
