FALSE SCOTOMAS ASSOCIATED WITH HIGH UNCORRECTED REFRACTIVE ERRORS

Archives of Ophthalmology, 1952
A CAUSE of false scotoma is deserving of presentation because the potential frequency of the type of scotoma is greater than the combined incidence of all other types and because false scotoma simulates a genuine scotoma so closely that it may be misleading. At the University of Michigan eye clinic we use a 10-mm. white circle for a fixation target at
