a Anterior segment photograph showing a spherical translucent vitreous cyst with irregular yellowish-brown pigmentation on its surface. b Anterior segment-optical coherence tomography showing a nonlobulated cyst, which had a thin cyst wall with punctuated thickening. c Ultrasound biomicroscopy showing ciliary body and posterior iris without obvious anomalies. d The cyst shifted to the posterior vitreous when the patient was in a supine position undergoing B-scan ultrasound, which showed a 2.2 mm × 1.5 mm hyperechogenic spherical structure without calcification, internal reflectivity, or attachment to ocular structures
