Clinical, fundoscopic, tomographic and angiographic characteristics of dome shaped macula classified by bulge height. / Estudio de las características clínicas, fundoscópicas, tomográficas y angiográficas de la mácula en domo según la altura de protrusión macular.

OBJECTIVE: To classify dome shaped macula cases by their bulge height (BH). To analyse the characteristics associated with the groups formed by this classification. METHODS: Observational, descriptive and cross-sectional study on 15 selected eyes with dome shaped macula and high myopia. Using Caillaux method and optical coherence tomography images, 3groups were determined by their BH: low (50-350 µ), medium (351-650 µ), and high (>650 µ), and a study of visual acuity, axial length, presence of subfoveal serous detachment, and images by fluorescein angiography and optic coherence tomography, as main variables. The confidence interval was 95%. RESULTS: By using the chi-squared test, the study showed that a BH higher than 400 µ was associated with lower visual acuity, presence of subfoveal serous detachment, and greater atrophy of the retinal pigment epithelium measured by disc diameters (P<.05). CONCLUSIONS: The medium and high BH showed a positive correlation with the presence of foveal serous detachment and a lower visual acuity.
