Clinical photograph, ultrasonographic fundus photograph and histopathology of right eye. (a) A brown protruding bulge occupied the entire nasal quadrant with a clear boundary seen at the outer edge of the corneoscleral limbus. The cornea was transparent, the anterior chamber was shallow and about 1/3CK, the pupil shifted up and dwindled with an apparent discoria. (b) B-scan showed vitreous opacity with posterior vitreous detachment. (c) The bulbar conjunctiva around the anterior staphyloma on the superior nasal quadrant was separated; the prolapsed uveal tissues and vitreous body were pruned during operation. (d) After surgical removal of the anterior staphyloma, the apparent thinning and perforated sclera at 12:00-2:30 position and iridoleptynsis on the superior nasal quadrant was observed. (e) The shifted-up iris was cut to recover a circular pupil and to clear vitreous hemorrhage by vitrectomy. (f) The removed specimens were confirmed as anterior staphyloma with the existence of pigment cells (arrowhead) by pathological examination. (g, h) Re-examination three months after operation: the right cornea was transparent, the stitches of corneoscleral junction on the superior nasal quadrant were eutopic, the anterior chamber was deep and the pupil was circular; the retina was procumbent by Panoramic200.

The cornea was transparent, the anterior chamber was shallow and about 1/3CK, the pupil shifted up and dwindled with an apparent discoria, the light reaction disappeared, and the fundus was not clear (Figure 1(a)). The right eye vitreous had an obvious opacity with posterior vitreous detachment (PVD) (Figure 1(b)) by B-scan. The bulbar conjunctiva around the anterior staphyloma on the superior nasal quadrant was separated; the prolapsed uveal tissues and vitreous body were pruned during operation (Figure 1(c)). Subsequently, we placed an apposition suture and covered the wound using the anadesma and conjunctiva (Figure 1(d)). We noticed a circular pupil, the hemorrhagic vitreous opacity, and the discus opticus with normal size and shape (Figure 1(e)). The removed specimens were confirmed as anterior staphyloma on histological examination (Figure 1(f)). The right cornea was transparent, the stitches at the corneoscleral junction on the superior nasal quadrant were eutopic, the anterior chamber was deep, and the pupil was circular (Figure 1(g)); the light reflex was slow, and the retina was procumbent by Panoramic 200 (Figure 1(h)).
