Medical Forum / General / Vision / July 2007OCT test
Hi Everyone, I just had an opthamology exam. The doc noted that my optic nerves were unusual but could be normal for me. I should have asked more quesionts but the appointment was hurried. I will have OCT and visual field tests in a month. Now I'm a bit worried. Does anyone know what kinds of things he might be checking for? He did say the pressures in my eyes were good.

I don't know the terminology but the concern was the thickness where the optic nerve enters the back of the eye. The thickness is in the lowest 1 percentile. This puts me on a 6 month recall for a re-test. If I understood him correctly this is glaucoma-like damage but that my eye pressures were still normal. Lots of worry where sight loss is a possibility. Dave > > Does anyone know what kinds of things he might be checking for? He did say > > the pressures in my eyes were good.

Try not to do too much of it.... > Hi Everyone, > [quoted text clipped - 9 lines] > > Dave Hi There is nothing to get worried about OCT,it is Optical Coherence Tomography which gives the status of your Macula which is likely to get degenerated due to age.If there are changes you will be asked to go in for some minor correction which not pailful and not time consuming.Do not get panicky about it it is similat to ECG or EEg and EOG. The OCT will provide your doctor with a cross sectional view of the retina. That is, from front to back through the retinal layers. Like looking at the side view of a cut of pie. As mentioned below (by Churie), the OCT can be used to evaluate the macula, but your doctor may be interested in the cross sectional view of your optic nerve. The OCT can provide this also.

Like [quoted text clipped - 16 lines] > > - Show quoted text - Hi Don FFA is Fundus Fluorescien Angoigraphy,a contrast media will be injected thru the veins and after a couple of minutes the contrast media reaches the eye and then pictures of the Eyes are taken,which gives the entire picture of the Retina which is very essential for a Retina Specialist to get a complete view of the Retina.FFA's are usually done maily on three catogeries namely, histroy of Prolonged Myopia,Diabetics and Hypertensives as they might have Retinal changes generally. The whole procedure takes hardly ten minutes and it is not painful and safe too. > > > > The OCT will provide your doctor with a cross sectional view of the > > > > retina.

Usually I call it a FA test. If I may add to what this test looks at is in the area of macular degeneration, as to leakage by new vessels. I think this FA (FFA) test is being tried to be eliminated by the OCT test for this purpose, but I don't think it can. Hard to beat the output of blood dye markers, showing blood path. Had this test once, missed the vein. (How many l's in painfull???). Don W. |
