Purpose: The authors intend to evaluate the eyelid position before and after the external prosthesis adaptation, using digital image processing techniques.
Methods: Eighteen patients were evaluated at the "Faculdade de Medicina de Botucatu-Universidade Estadual Paulista-UNESP", with and without the external prosthesis. Qualitative and quantitative analysis were done using the Scion Image program. The superior eyelid sulcus distance, margin eyelid distance and eyelid medial and lateral canthus angles were evaluated.
Results: Pseudostrabismus and high eyelid sulcus were the most observed alteration. The superior eyelid sulcus distance had shorter values with the prosthesis and higher values were seen analyzing the other parameters when the external prosthesis was in place.
Conclusion: All patients had some abnormalities, which show us how difficult it is to provide a normal aspect for anophthalmic cavity carriers. The image processing allowed objective evaluations of the measures contributing to the follow-up of the patients.
