Re: Re: Eye question (number of cells)

Re the number of cells, I found the folowing explanation:

Cells are collections of white blood cells (leukocytes) in the anterior chamber of the eye where they can be observed on slit lamp examination floating in the convection currents of the aqueous humor. The number of cells in the anterior chamber can be counted in the narrow beam of light from the slit lamp. This forms the basis for grading the severity of inflammation at any given point in time. The amount of white blood cells is the measure of uveitis activity, and is scaled from 1 to 4, depending on the severity (1 being the least severe inflammation and 4 being the most severe inflammation).The right hand table is the grading of aqueous cells in anterior uveitis used at MEEI.

Inflammatory cells in the anterior chamber are usually a result of inflammation of the iris.Cells are difficult to capture in photographs.

See, also, FLARE.

GRADING OF AQUEOUS CELLS

Number of cells

observed Grade

0 No Cells

1-5 1/2+

6-15 1+

16-25 2+

26-60 3+

Greater than 60 4+

Cells can also be observed in the vitreous on dilated examination. Inflammatory cell accumulation in the vitreous is the result of inflammatory process in other intraocular structures such as the ciliary body, retina, and choroid. Cells in the vitreous can be living or dead, and both can become immutably affixed to vitreous fibers. Only live, active cells are graded in the MEEI rating system. Vitreous cells are rated on a scale of 1-4 , as follows: 1/2+=1-10 cells. 1+=11-20 cells. 2+=20-30 cells. 3+=30-100 cells. 4+=grater than 100 cells. Other institutions use other rating systems to grade vitreous cells.

Hope this helps!

Thanks Diane. This is the most thorough explanation I've seen. Where did you find it?

Therese-

The information is from www.uveitis.org, which contains a wealth of articles and information.

Thank you also for this I knew that they said 1+ flare but did not know what that really meant....Terri

Re: Eye question (number of cells)

Diane - Thank you so much for this! This article explains soo much better what I was trying to say. I think I might even know what my doc. is talking about now!
