    Abstract:
    PURPOSE: This study used optical coherence tomography scanning and 3D reconstruction of the macular region in high myopia to examine more thoroughly and carefully the differences between high myopia-related macular complications with and without dome-shape macula (DSM) and to determine whether the DSM's fine structure has an effect on them. METHODS: Retrospective analysis of the medical records of 345 eyes with high myopia who underwent an optical coherence tomography (OCT) examination. They were divided into the DSM group (69 eyes) and the group without DSM (276 eyes). Macular complications between the two groups were compared. The height of the DSM and the diameter of the dome base were measured. And then the association between DSM type, protrusion height and macular problems were analyzed. RESULTS: Epiretinal membrane (ERM) and extrafoveal schisis occurred more frequently in the DSM group, but the was no statistically significant difference in the frequency of foveal schisis between the two groups. The majority of eyes in the DSM categorization had a horizontal oval-shaped domain. In the DSM group, there was no evident difference in the percentage of eyes with macular complications in the groups below 150 um and above 150 um. CONCLUSIONS: OCT examination-based fine macular structure analysis reveals that DSM affects various macular problems in distinct ways. DSM could increase the risk of extrafoveal schisis and ERM while decreasing the risk of foveal schisis. The height of the DSM had no obvious impact on the prevalence of macular complications.
