A Study was conducted to investigate the relationship between dome-shaped maculas (DSMs) and posterior staphylomas in highly myopic eyes.

Analysis was done of 511 eyes with high myopia that 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:
--82 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.

--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.

Finally, the absence of staphylomas in 45% of DSM eyes indicates that DSMs grow independently of posterior staphylomas. Dome-shaped maculas are more common in eyes with a broad posterior fundus expansion and should be viewed as a posterior scleral curvature abnormality.
