To report a bilateral case of morning glory syndrome.

On May 30, 2002, a six-year-old patient visited our clinic with impaired visual acuity of her left eye and was diagnosed as having a cataract on her left eye superimposed on a bilateral morning glory anomaly. According to cycloplegic refraction, the patient's corrected visions was 0.8 in the right eye and 0.1 in the left. On June 20, 2002, the patient received ultrasonographic phacoemulsification, intraocular lens implantation, synechiolysis and partial vitectomy in her left eye. Approximately 5.2 years after the surgery, according to manifest refraction, the patient's corrected visions were 0.8 in the right eye and 0.1 in the left, no prominent postoperative changes were observed on slit lamp microscopy and fundus examinations. The thickness of the central macula of her right eye had decreased according to optical coherence tomography; the physiologic scotoma size of the patient's right eye had increased with narrowed peripheral visual field of her left eye.

Although monocular morning glory anomaly has previously been reported to occur, in the present study case, the anomaly occurred bilaterally. In morning glory patients, strabismus examination and additional evaluation of a patient's general state should be performed along with a regular fundus examination.
