Abstract
PURPOSE: To investigate the relationship between dome-shaped maculas (DSMs) and posterior staphylomas in highly myopic eyes. METHODS: Five hundred and eleven eyes of 291 patients with high myopia (refractive error ≤-8.0 diopters or axial length ≥26.5 mm) were examined by ultra-widefield swept-source optical coherence tomography (UWF-OCT). Posterior staphylomas were identified by detecting the staphyloma edges in the UWF-OCT images. RESULTS: Eighty-two eyes of the 511 highly myopic eyes had a DSM, and a posterior staphyloma was observed in 45 of 82 eyes with a DSM (54.9%) and in 301 of 429 eyes (70.2%) without a DSM. The incidence of staphylomas was significantly lower in eyes with a DSM than those without a DSM (P = 0.007). The wide macular type of staphyloma was the predominant type in eyes with a DSM (31/45 eyes; 68.9%), whereas the narrow macular type and wide macular type of staphylomas were present almost equally in the eyes without a DSM. CONCLUSION: The lack of staphylomas in 45% of eyes with a DSM suggests that DSMs form independently from posterior staphylomas. Dome-shaped maculas tend to occur in eyes with a large expansion of the posterior fundus and should be considered a posterior scleral curvature abnormality.
