“…The formation of a staphyloma includes visually important tissues, such as the optic nerve head and the macular retina, which can significantly affect the visual prognosis of highly myopic patients. 1,11 The quantitative assessment of staphylomas could thus be a step to establish treatments targeting the development of staphylomas before blinding complications occur. In addition, the relationship between a staphyloma and other tissues that could influence the scleral shape (such as vitreous, intrascleral/episcleral vessels) may be an interesting theme to be examined.…”

“…Based on their ophthalmoscopic appearance, Curtin 1 differentiated posterior staphylomas into 10 different types in 1977. Later, Moriyama and colleagues 9,10 applied three-dimensional magnetic resonance imaging (3D-MRI), and Ohno-Matsui and coworkers 11,12 used a combination of 3D-MRI and ultrawidefield fundus imaging to classify posterior staphylomas into six different types, based on the size, shape, and location of the staphylomas.…”

PURPOSE. To examine posterior staphylomas by widefield optical coherence tomography (WF-OCT) and three-dimensional magnetic resonance imaging (3D-MRI).METHODS. Highly myopic patients (myopic refractive error >8.0 diopters or axial length >26.5 mm) who had previously undergone orbital 3D-MRI were examined by WF-OCT. RESULTS.The study included 100 eyes of 57 patients with a mean age of 67.9 6 10.7 years (range, 44-85 years) and mean axial length of 30.0 6 2.3 mm (range, 25.1-36.5 mm). All staphylomas detected on the 3D-MRI, except for two very large staphylomas, were visualized on the WF-OCT images. Morphologic hallmarks of the staphylomas were smoothly configured staphyloma border with a gradual thinning of the choroid and an inward protrusion of the sclera at the staphyloma edge. Comparing the detectability of the staphylomas on the WF-OCT images versus 3D-MRI revealed no significant difference between both techniques (P ¼ 0.12; v 2 test). Comparing the staphyloma classification between both techniques showed a good concordance with a concordance index kappa of 0.61 (95% confidence interval: 0.50-0.72). A spatial relationship between the staphylomatous areas and the macula and optic nerve head was observed by WF-OCT.CONCLUSIONS. WF-OCT can provide tomographic images of posterior staphylomas in a resolution and size unachievable so far, and may replace 3D-MRI in assessing posterior staphylomas. Future studies using WF-OCT may explore the detailed morphologic characteristics of posterior staphylomas and give clues to the etiology of staphylomas.

“…Some myopic eyeballs expanded globally, some eyeballs expanded in axial length only. It is difficult to compare the incidence of staphylomas among the studies using traditional eye examinations, because of differences in the definition of staphyloma, the methods used to detect a staphyloma, and the characteristics of the patients [30] .…”

Purpose: To quantitatively analyze the shape of eyes with high myopia and provide assistance for posterior scleral reinforcement (PSR) using high-resolution three-dimensional (3D) magnetic resonance imaging (MRI). Method: In all, 260 eyes of 134 patients with high myopia were assessed in this study; 120 emmetropic volunteers were enrolled as a control group. The subjects were examined using 3D T2-weighted CUBE sequences. Results: The eyeballs' axial, horizontal, and vertical lengths were longer and their volume was larger in the subjects with high myopia than in those with emmetropia. The sites of the four recti and optic nerve attachment to the eye were clearly seen on 3D MRI, and the geometric information could be quantified for PSR preparation. The scleral strip was revealed by 3D MRI after surgery. Conclusions: 3D MRI can quantitatively analyze the shape of eyes with high myopia. 3D MRI examination might be necessary before and after PSR for preoperative preparation and postoperative assessment.
