Abstract: :
Purpose: To determine the occurence of artifacts in the routine use of Optical Coherence Tomography (OCT) in the study of macular pathology. Methods: We analyzed the incidence of errors subdivided into categories according to their origin. Additionally the errors's influence on the diagnosis was studied. Results: The most frequent errors occurred on the basis of the length, orientation and location of the scans. The errors consisted: 1) in the correct dimension of macular hole, especially in myopic eyes; 2) in the shape of fovea area; 3) in the differential diagnosis of macular edema. Conclusions: OCT may generate secondary images depending on not accurate determination of tomography images. The occurence of errors suggest that it is imperative to have an individual and attentive analysis of OCT scans.
