A new technique of visual field evaluation for unilateral ptosis.
A technique of uniocular visual field testing under binocular viewing conditions for evaluation of unilateral ptosis is described. The eye with the nonptotic lid is covered with a red filter, and both eyes fixate the white fixation light while a green test light is used. The resultant field reveals the true functional field loss due to the ptosis and avoids changes due to the patient elevating his brow.
