ABSTRACT

Aim: to identify the rate of retinal thickening in Mexican diabetics with macular edema, in order to spot thickness values useful for its detection.
Methods: Macular thickness by field was measured with optical coherence tomography in diabetics without retinopathy (group 1) and with clinically significant macular edema (group 2). Differences were compared among groups (Mann-Whitney’s U) and the rate of thickening in group 2 compared to group 1 was estimated.
Results: 24 eyes per group were evaluated. Mean thickness in group 1: field 1 (central) 186.4 µm, 2 (internal temporal) 256.6 µm, 3 (internal inferior) 262.µm, 4 (internal nasal) 246.8 µm, 5 (internal superior) 269.5µm, 6 (external temporal) 246.2µm, 7 (external inferior) 229µm, 8 (external nasal) 217.8 µm, 9 (external superior) 241.2µm. Fields 1, 2, 4, 6, 7 and 8 showed statistical differences. Thickening in group 2 ranked from 10.4 to 40.1% (maximal: 65µm).
Conclusions: Macular thickness differed statistically between patients with and without edema, but was smaller than that reported; macular thickness changes could identify edema in 70% of the fields. The differences found with international standards could lead to overestimation of therapeutic results.
