ABSTRACT
OBJECTIVE: To evaluate the ophthalmic, radiologic, and ultrasonographic findings in morning glory syndrome. PATIENTS AND METHODS: Retrospective review of patients' charts. RESULTS: Twenty-one patients were included. Visual acuity was 20/200 or better in 50% of the eyes. Three eyes developed a retinal detachment. When computerized tomography of the orbit demonstrated peripapillary scleral staphyloma and intraocular calcifications, this correlated with poor visual acuity. Computerized tomography of the brain revealed abnormalities in three asymptomatic patients. B-scan ultrasonography demonstrated retinal tissue overhanging the peripapillary scleral staphyloma. CONCLUSIONS: Morning glory syndrome has a spectrum of severity, with most patients retaining useful vision. Orbital and cerebral computerized tomography scan as well as B-scan ultrasonography may help with diagnosis and management.

The aim of the study was to evaluate the pattern visual evoked potentials (PVEP) combined with an optimal state of vigilance, called liberated state (LS), in order to improve testing in very young infants. Transient PVEP were recorded in response to a checkerboard pattern of 120, 60 and 30 min of arc. in 56 fullterm newborns and 79 preterm infants from birth to 4 months of age. In the fullterms, 28 infants in each group were tested in LS or spontaneous alertness (SA) while in the preterms, 48 infants in each group were tested in LS or SA. No significant difference was found in the amplitude and/or peak time of the PVEP responses between subjects tested in LS compared to SA groups. However, the LS condition improved by approximately 25% the feasibility of prolonged PVEP testing in preterms aged less than 2 months (corrected age). This suggest that the LS condition enhances the clinical feasibility of PVEP testing in very young infants and should be used to optimize the evaluation of visual development in high risk infants in this age group.
