Measuring units for Glaucoma???

Question:

Hi Ian, Thank you for your answer. And yes, my ophtalmologist says it is congenital glaucoma with no doubt. I still don’t understand something and I hope that you can clarify it. The IOP in right eye is measured to be 2 units, while the IOP on left eye is equal 1 unit. And you say that this means pressures of 34mmHg on each eye. Was this your mistake? Is (34mmHg = 1Schioetz unit) or (34mmHg = 2 Schioetz units) ? Besides, for which weight is this translation valid (5.5gr  or maybe  7.5gr)? My ophtalmologist says that operations have to be done to reduce the pressure. But as the kid is too small (only 9 days old), the operations must be postponed for at least one month. I am afraid that this pressure might produce some irepairable damage during this month of waiting. Is it usual to wait so long before anything is done? How high is this risk?    Lav – Hide quoted text — Show quoted text -"Ian Hodgson" <i…@enterprise.net> wrote in message news:PIY56.5$hE2.3747@news.enterprise.net… > Lav Kovacic <lav.kova…@inet.hr> wrote in message > news:937ga3$vr1$1@sunce.iskon.hr… > > Hi all, > > I am just looking into ophtalmologist findings of my 8 days old child. > > Unfortunately, a glaucoma was diagnosed.

Hello Lav, Some of this is guessing but it if the ophthalmologist was using a Schioetz tonometer, not an instrument used these days in the UK, then the pressures were about 34mmHg in each eye. I have an old one which is kept as a reminder of the old days!! I assume T=pressure .  OD= ocular dexter  OS= ocular sinister  (latin for Right Eye and Left Eye respectively). Normal IntraOcular Pressure is usually given as 16mmHg (by Goldmann Applanation Tonometer) Schioetz used to be higher about 18 to 20mmHg (I think). Different methods of measurement slightly different values. 34mmHg is high and in a child be treated with some alarm. It is possible that your 8 day old may have congenital glaucoma. However the only person who can say this with confidence is your ophthalmologist. Hope this helps Ian Hodgson BSc FCOptom

Hi all, I am just looking into ophtalmologist findings of my 8 days old child. Unfortunately, a glaucoma was diagnosed. Does anyone understand the following abbreviations and numbers: TOD(5.5 gr): 2.0 jed   TOS(5.5 gr): 1.0 jed ("jed" could maybe be an abbreviation of Croatian word "jedinica" which means unit) I suppose that these are results of measuring of intraocular pressure, but I don’t know the meaning of these units. How many units would be measured on healthy eyes? Can these units be translated into mmHg units? How alarming are these findings? Thanks in advance    Lav
