Feasibility of saccadic vector optokinetic perimetry: a method of automated static perimetry for children using eye tracking.

PURPOSE: To determine the feasibility of a new technique for suprathreshold automated static perimetry in children. DESIGN: Evaluation of diagnostic test or technology. PARTICIPANTS: The study included 29 subjects comprising 4 groups: 12 adults with normal fields, 4 children aged less than 10 years with normal fields, 8 adults with visual field defect, and 5 children aged less than 10 years with suspected visual field defects. METHODS: The system comprises a personal computer, display, and eye tracker to monitor gaze position when stimuli are presented in the visual field. The natural saccadic eye movement to fixate on the stimuli, if seen, can be detected and measured to produce a visual field plot. Subjects performed 3 eye-tracking tests, unless unable to do so for any reason: a 40-point binocular test and two 41-point tests for each eye. The tests were based on the Humphrey Field Analyzer (HFA) Central-40 point screening test with a stimulus size of Goldmann III and intensity of 14 decibels (dB). Adults also performed the equivalent Humphrey screening test in each eye for comparison. MAIN OUTCOME MEASURES: Comparison of visual field plot results between the eye-tracking tests and HFA tests in adults. Correlation between the eye-tracking tests and the clinical assessment in the children with suspected visual field defects. RESULTS: In the eyes of all normal adult and child subjects performing the eye-tracking test, the percentage of points in agreement with a healthy visual field was 99.2% and 99.1%, respectively. The percentage of points agreeing with the HFA's screening test in the adult eyes with visual field defects was 89.8%. Visual field defects were also correctly identified by the eye-tracking system in the eyes of children with suspected visual field defects. CONCLUSIONS: The results demonstrate that suprathreshold automated static perimetry using eye tracking is a promising method of perimetry for use with children.

Adams-Oliver syndrome associated with bilateral anterior polar cataracts and optic disk drusen.

Adams-Oliver syndrome (AOS) (MIM 100300) was first described in 1945 as a condition of terminal transverse limb defects and aplasia cutis congenita. Since then, its clinical features have been found to be highly variable and include cardiac defects, abdominal wall defects, vascular malformations, brain abnormalities, and ocular anomalies. We report the case of a 3-year-old girl with AOS who was also found to have bilateral anterior polar cataracts and pseudopapilledema secondary to optic disk drusen. To the best of our knowledge, this is the first case of bilateral anterior polar cataracts and pseudopapilledema secondary to optic disk drusen to be reported in association with the AOS.

Myofibroma of the conjunctiva invading the cornea in infancy.

The authors report a novel case of solitary infantile myofibroma originating from the conjunctiva and encroaching over the limbus. This is an observational case report with clinicopathologic correlation. Immunostaining of the lesion was positive for vimentin and smooth muscle actin, and negative for pancytokeratin, desmin, myogenin, EMA, myoglobin, HMB45, and MelanA. To the authors' knowledge, this is the first reported case of myofibroma originating from the conjunctiva and this case highlights the importance of considering myofibromatosis in the differential diagnosis of unusual conjunctival lesions.
