To the Editor.—
In "Nits or Not?: Pseudonits—Simple Office Diagnosis" (243:2325, 1980), the authors state "almost invariably these prove to be hair disorders that mimic nits of pediculosis capitis and can easily be differentiated solely with the aid of a microscope."The ophthalmoscope is, however, a more convenient instrument and is available to all primary physicians at the time of the initial examination. By its use, the physician can easily differentiate nits from nots. The ophthalmoscope is held in its normal position to the examiner's eye, and the hair, with its abnormality, is examined using a 10, 20, or 40 diopter setting.Incidentally, many other dermatologic lesions are also easily examined under magnification by use of the ophthalmoscope.
