In macular degeneration, how well do the symptoms reported by the patient correlate to what the ophthalmologist sees via OCT and direct retinal photographs? That is, can the ophthalmologist "see ahead" of the reported symptoms, or is the "inside view" always better? Or what....? > In macular degeneration, how well do the symptoms reported by the patient > correlate to what the ophthalmologist sees via OCT and direct retinal > photographs?

Often the retinal signs precede vision loss by many years, so regular examinations are most important in detecting AMD early. Once AMD develops, patient monitoring with Amsler grid is an essential part of treatment because you can detect blind spots and stretching about as accurately as the best instruments. Other problems (like neovascular nets) don't affect your subjective vision enough to be reliable. I haven't seen figures comparing OCT in AMD management, but I'm pretty sure fluorescein angiography is still the best way to identify areas that need treatment. -MT > In macular degeneration, how well do the symptoms reported by the patient > correlate to what the ophthalmologist sees via OCT and direct retinal > photographs? Not well. For example, you can find patients that seem to have advanced AMD by fundoscopic exam but also have excellent Snellen acuity. Vice versa, you can find patients who seem to have nothing more than some minor pigment mottling but have lost 1-2 lines of acuity. Interesting about the Snellen acuity. The drug Macugen, in the FDA trials, used this type of test to get approval. >> In macular degeneration, how well do the symptoms reported by the >> patient correlate to what the ophthalmologist sees via OCT and direct [quoted text clipped - 4 lines] > versa, you can find patients who seem to have nothing more than some minor > pigment mottling but have lost 1-2 lines of acuity. |
