Clinical, fundoscopic, tomographic and angiographic characteristics of dome shaped macula classified by bulge height

To classify dome shaped macula cases by their bulge height (BH). To analyse the characteristics associated with the groups formed by this classification.

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%.

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).

The medium and high BH showed a positive correlation with the presence of foveal serous detachment and a lower visual acuity.
