[Ultrasound Manifestations of Eyes of Pediatric Patients with Morning Glory Syndrome].

Objective: To analyze ultrasonic manifestations of eyes of pediatric patients with morning glory syndrome (MGS).

Methods: Clinical data and ultrasound (US) findings for six children (4 males and 2 females, 5-60 months old) diagnosed with MGS between 2005 and 2016 were reviewed.

Results: Of the 12 eyes, seven were diagnosed with MGS; one with cataract; the other four were normal. One child had both eyes diagnosed with MGS. Of the seven eyes with MGS (5 right, 2 left), one was small associated with persistent hyperplastic primary vitreous (PHPV); 2 had retinal detachment. Findings of high frequency ultrasound included local anechoic lesions with distinct boundary showing a convert bottle-neck shape that appeared in the area of optic disk of posterior pole. The lesions communicated with the vitreous caicy and extended to the optic nerves. The lesions had a maximum depth of 4-15 mm [(8.29±4.42) mm] and a maximum width of 4-11 mm [(6.86±2.67) mm]. Hypoecho material was found in the bottom of five of the seven lesions. The distance between the end of the optic nerves and the bottom of the lesions ranged from 0 to 4.5 mm. Lower levels (Adler 0-1 grade) of blood flow in the bottom of the lesions were found compared with those (3-5 grade) in the rim of the lesions.

Conclusion: MGS is rare and usual occurs in young children, especially infants. It is often associated with various eye complications. The ultrasound manifestations of MGS are characterized with a local anechoic lesion mimicking a convert bottle-neck shape in the area of optic disk of posterior pole.
