Visual fatigue phenomenon and prescribing tinted lenses in patients with optic neuritis.

The fatigue phenomenon of grating visual acuity was examined in 36 patients with optic nerve disorders by means of a laser interferometric acuity device. The phenomenon was found in 6 of 36 cases even under a luminance corresponding to the Japanese standards of office illumination. This fact indicated that the patients suffered visual fatigue in their everyday vision. After they were prescribed tinted lenses to eliminate the fatigue, the patients had comfortable sustained vision in their daily work.

Supraliminal contrast sensitivity functions in recovered optic neuritis.

The supraliminal contrast sensitivity functions in patients with recovered optic neuritis were classified into three function types: 1) type with a decrease in sensitivity in the high and an increase in the low spatial frequency region, 2) type with flat shape as found in normal subjects, and 3) type with a decrease in the low and an increase in the high frequency region. These abnormal functions may be explained by an inhibitory interaction between two parallel channels of high and low frequency, which may have a dependence on the most central and the paracentral region in the visual fields, respectively. The measurements of the supraliminal contrast sensitivity functions are clinically useful for understanding the visual processes in cases with recovered optic neuritis.

Tuberculosis of the tongue. A case report with immunologic study.

A case of tuberculosis of the tongue in a 59-year-old woman with active pulmonary tuberculosis is described. The lingual tuberculosis was considered to be a secondary infection from the pulmonary disease, but the oral lesions were, in fact, noticed prior to recognition of the pulmonary lesion. This case was marked by a multiplicity or oral lesions arising on the bilateral surfaces of the tongue. Immunologic investigation revealed that cell-mediated immune responses in the patient were within the normal range in terms of the PPD skin test, DNCB skin test, lymphocyte transformation test, and subpopulation of the peripheral blood lymphocytes. Rosette-forming assay on the frozen sections disclosed that T-lymphocytes and macrophages were predominant in the lymphoid cells infiltrating the tuberculous lesion.

Surveillance and follow-up of patients with implanted cardiac pacemaker by telephone transmission.

A follow-up study on pacemaker function in 15 patients with implanted cardiac pacemaker has been performed by telephone transmission. The transmitting set consisting of electrocardiograph, pacemaker pulse modulator and acoustic coupler was manipulated by the patients themselves. ECG, pacemaker pulse, and pulse rate were simultaneously transmitted through 1 channel to the receiver in our clinic. Of 56 patients with pacemaker, 15 patients were surveyed by telephone transmission. In these patients battery exhaustion was detected in 3, competition in 2, and lead fracture in 1. The fact that surveillance and follow-up of the patients with implanted cardiac pacemaker could be carried out by telephone transmission as well as by clinic visitation tells us that the telephone transmission is a useful method and plays an important role in a pacemaker clinic. Moreover our study established its further usefulness in the patient's preference due to difficulties in travelling to the pacemaker clinic and in reducing patient's anxiety.
