    Abstract:
    OBJECTIVE: To investigate the clinical features of Best vitelliform macular dystrophy (BVMD) in Chinese patients. METHODS: Ten consecutive patients (20 eyes) were diagnosed as BVMD by the fundus photography, EOG, fluorescein angiography (FFA) and optical coherence tomography (OCT). Their clinical data were analyzed retrospectively. RESULTS: Of the twenty eyes from ten patients, three eyes from three patients (age range 9-18 years, mean 12.33+/-4.93 years) in Stage II, two eyes from two patients (age range 9-18, mean 13.50+/-6.36 years) in Stage IIa, four eyes from two patients (age range 11-29 years, mean 20.00+/-10.39 years) in Stage III and eleven from six patients (age range 9-44 years, mean 27.09+/-14.02 years) in Stage IV were found at their first presentation to our hospital. OCT scan showed the broadening of the outer-retina-choroid-complex signal with the retinal elevation in Stage II. The moderately reflective material which represents the vitelliform material may accumulate forming a conical mound that would elevate the retinal sensory layer in Stage IIa. In 'pseudohypopon' or atrophy phase there may be a large volume of serous retinal detachment. If a fibrous macular or foveal atrophy was seen in the fundus photograph, the thinning of the outer-retina-choroid-complex signal with serous retinal detachment may be shown by OCT. CONCLUSIONS: The present observation is a first study on the clinical findings of Chinese BVMD patients. It supports the hypothesis that the yellowish material is located under the RPE. Long term evaluation with more patients should be done to acknowledge more characteristics of BVMD in Chinese patients.
