Six eyelashes, three from the upper lid and three from the lower lid, were epilated from 256 subjects and examined for Demodex. D. folliculorum (Simon) was found in 16% of the subjects. Mites were more abundant in older persons and in persons with diabetes. Mites also were associated with a scarcity of lashes in the lower lid. Hierarchical log-linear(More)
The perceived orientation of a central test grating is influenced by the orientation structure of the surrounding image. Measurement of this "tilt illusion" traditionally requires subjects to report the orientation of the test relative to a cardinal reference (e.g., clockwise or anticlockwise of vertical). Given that the test is presented within a surround(More)
Prior expectation may influence our perception of people at the first meeting. For example, it has been shown that we are more likely to categorise a person as 'male' or to estimate their age as closer to our own. This could be due to perceptual effects and/or cognitive response bias. Here we use a forced choice task to reduce cognitive influence and a(More)
A person's appearance contains a wealth of information, including indicators of their sex and age. Because first impressions can set the tone of subsequent relationships, it is crucial we form an accurate initial impression. Yet prior expectation can bias our decisions: Studies have reported biases to respond "male" when asked to report a person's sex from(More)
We report on a patient who had an excessive number of mites (Demodex folliculorum) on his eye lashes, i.e. 10 mites on eight lashes examined. A review of three previous reports suggested that one mite for every two lashes represents an over population of this nearly ubiquitous mite. Greasy scales on the lashes and foamy tears suggested that seborrhea was(More)
