Abstract:
The thickness of the retina, choroid and sclera in relation to macular oedema (ME) can be measured using A scan echography. Ninety diabetic patients (180 eyes) divided into two groups with and without ME, respectively, were studied compared to a third group of 73 healthy controls (146 eyes). Statistical analysis of results showed good specificity (80%) and reasonable sensitivity (70%) of the echographic method in showing the presence of ME confirmed by fluorescein angiography.
