Objective: To evaluate the Retinal Thickness Analyzer (RTA) findings in eyes with macular hole and compare them to findings of retina and vitreous biomicroscopy, retinography and fluorescein angiography. Methods: The authors studied ten eyes of six patients with the diagnosis of macular hole, using retinal thickness analyzer, retina and vitreous biomicroscopy, retinography and fluorescein angiography. Eight eyes had been examined before any type of treatment, and two, after treatment for macular hole by vitrectomy. Results: In two eyes with the diagnosis of macular hole by clinical examination and other complementary examinations, the media opacities prevented retinal thickness analyzer analysis. The retinal thickness analyzer profile map (optical cut) showed agreement with the clinical findings and the findings by other examinations performed in the eight eyes where they were possible. The topographic map of the two eyes that presented a closed macular hole after surgery, showed normal mean foveal thickness and in the six eyes with macular hole the mean foveal thickness was increased. Conclusion: The retinal thickness analyzer profile map showed evidence of macular hole, gave information about width and depth and proved the closing of the macular hole after surgery. The retinal thickness analyzer topographic map showed normal mean foveal thickness in the two cases of closed macular hole and, surprisingly, increased mean foveal thickness in all six cases with open holes.
