Yes, the consultant said it can halt the progress and is a very expensive treatment. He also said why didn't you see us before which was rather annoying as It had been diagnosed as 1st stage retinopthy at my annual diabetic clinic last August. The letter said, no treatment needed, see you in a year. 2 opticians also said retinopthy but the last didn't like the look of so arranged a visit to the hospital which was yesterday. Very scary as I'm wondering how many more are misdiagnosed and then it may not be treatable.
The annual diabetic eye screening is only funded to look for diabetic retinopathy (which includes diabetic maculopathy). Other eye conditions are generally dealt with by opticians who can write to the patient's GP requesting a hospital referral. Having said that, some conditions are so urgent or important that the diabetic eye screening programme will ensure that there is a referral even if the condition is not diabetic retinopathy. One of these conditions is
wet AMD which develops very rapidly and can have a severe effect on eyesight.
Because wet AMD progresses so quickly, if any signs of it are detected at the diabetic eye screening, the programme will try to ensure that the patient is seen in hospital within 2 weeks of their screening date. Sometimes early wet AMD can look like maculopathy which would mean that the patient would be referred routinely (13 weeks) rather than urgently. It would be very unusual for wet AMD to be confused with a level of diabetic retinopathy that is so low that the patient is given an annual recall outcome.
Even if early wet AMD was not picked up at screening, it would not take months to develop but should be noticed very quickly by the patient as a
sudden change in vision. This may be a drop in 'visual acuity' (the line that can be read on the eye chart) and/or distortion of straight lines and/or blind spots in the vision. If this happens, the patient needs to see their optician ASAP as central vision can be lost within days.
All results letters from the diabetic eye screening programmes should contain a paragraph advising patients to see an optician if they have any problems with their eyesight between screenings and
not to wait for their next screening. Most cases of wet AMD will develop between screenings.
For clarity: Wet AMD is preceded by
dry AMD. There is no treatment for dry AMD which affects central vision more gradually and less severely than the wet form. Only some cases of dry AMD progress to wet AMD. Anyone who has been informed that they have dry AMD should be aware of the possibility of developing wet AMD and they may benefit from using an Amsler grid weekly to help test for it:-
