ABSTRACT

Purpose: To analyze the topographic distribution of diabetic macular edema, using (optical coherence tomography) in order to identify whether there are zones that are particularly vulnerable to develop it.
Methods: The rate of involvement was compared (χ2) in patients with clinically significant macular edema and retinal thickness above that considered normal in fields: 1 (central); 2 (internal temporal), 3 (internal inferior), 4 (internal nasal), 5 (internal superior) 6 (external temporal), 7 (external inferior), 8 (external nasal) and 9 (external superior) of the OCT 6 mm fast macular map; the rate of fields affected per eye and the association between the involvement of a field and foveal center involvement was determined.
Results: 56 eyes (mean age 58.9). Fields most commonly involved: 8 (78.6%), 9 (76.8%) and 7 (75%). The rate of edema did not differ among fields (p=0.15). 54 eyes (96.4%) had involvement in more than one field (mean 6.5). The only field whose involvement was statistically associated to foveal thickening was field 1.
Conclusions: The rate of edema did not differ statistically among fields, probably as a result of the high rate of multiple involvements. There is no support to consider that any field is particularly vulnerable to develop edema.
