[QUOTE="Dark Horse, post: 1693223, member: 52527"] The annual photos taken by the Diabetic Eye Screening Programme are a part of a [U]screening[/U] test designed to detect sight-threatening diabetic retinopathy before any symptoms develop. Although the test sometimes detects other eye conditions, it is not designed to do so. This is why patients are told to also attend the optician regularly and to go to the optician or GP if symptoms do develop between screenings and not to wait for the next screening. The Programme does not usually concern themselves with cataracts unless they are so bad that the screening photos are unassessable. A 'normal' result means that no sight-threatening diabetic retinopathy has been detected, it doesn't tell you anything about whether you have cataracts or any other eye condition. Like any screening test, the test for sight-threatening diabetic retinopathy is not (and can never be) 100% accurate and so false negatives do occur. Although diabetic macular oedema (a type of sight-threatening diabetic retinopathy) is one cause of reduced vision (usually detected by OCT scans like those [USER=101136]@Jaylee[/USER] supplied), there are other non-cataract causes such as vein occlusions, central serous retinopathy, epiretinal membrane, age-related macular degeneration, glaucoma, retinal detachment etc. etc.. Without knowing what your next appointment is for, it's impossible to speculate whether your screening test was a 'false negative'. With a vein occlusion, for example, it's possible that it could occur after the screening test and after the optician eye test but before trying the glasses and before the hospital eye test. This would explain why the screening test was normal and why the prescribed glasses didn't help.
