Yellow mercuric oxide: a treatment of choice for phthiriasis palpebrarum.

Thirty-five patients presenting with phthiriasis palpebrarum were all treated with a regimen of 1% yellow oxide of mercury ointment four times daily for 14 days. At the conclusion of treatment there was complete resolution of the signs and symptoms of the disease. No side effects due to the treatment were reported or detected. We have shown that 1% mercuric oxide ointment is both a safe and effective treatment for phthiriasis palpebrarum. We recommend it as the treatment of choice.

Glaucoma in siblings with Morquio syndrome.

Two cases of association between the Morquio Syndrome and glaucoma in one family are described. Possible role of Mucopolysaccharides acting in the anterior chamber angle is discussed.

Usher's syndrome: electrophysiological tests of the visual and auditory systems.

The symptoms of Usher's syndrome - congenital hearing impairment and tapetoretinal dystrophy - are difficult to detect in young children. The electroretinogram (ERG), visual evoked potential (VEP), auditory nerve and brain-stem responses as well as the cochlear microphonic potentials were used to evaluate the defects of the visual and auditory systems in 20 patients, 3-45 years of age. This study demonstrates the usefulness, reliability and convenience of the electrophysiological tests for early diagnosis and functional evaluation of Usher's syndrome.

A telemeter without refractive optics.

A conic tube may be adjusted by varying the distal diameter and by using binocular vision for measuring distances. This device appears to be the earliest telemeter in the world. It is mentioned in the Talmud as being used in the first century A.D.

Sector retinitis pigmentosa: a fluorescein angiographic study.

Flourescein angiography has been proved to be of value in the study of the chorioretinal abnormaliteis in sector retinitis pigmentosa. The findings from two patients, one being in an early and the other in a more advanced stage were analyzed. The pigment epithelium was found to be disturbed in a larger area than visible by ophthalmoscopy. In the impaired quadrant the retinal vessels were narrowed showing delayed and slow dye transit. Through the discolorated pigment epithelium leaky choriocapillaries were disclosed. Moreover, in the severly affected patient, areas missing choriocapillar perfusion and retinal circulation were also detected.

Sector retinitis pigmentosa. Electrophysiological and psychophysical study of the visual system.

Combined clinical, psychophysical and electrophysiological examinations of the visual function were performed in two patients affected by sector retinitis pigmentosa. Psychophysical dark adaptation measurements, the electroretinogram (ERG) and the electro-oculogram (EOG) revealed that a larger area of the neural retina and pigment epithelium were pathologically involved than revealed by ophthalmoscopy and visual field. Five years of observation showed a stationary retinal defect in one patient, while in the other a slight clinical but a marked electroretinographical deterioration was found over a period of twelve years. However, visual acuity and the visually evoked potential (VEP) remained normal. In spite of subnormal ERG amplitudes, the photopic and scotopic peak latencies were normal in both cases. In the ophthalmoscopically normal relatives of one patient slight dark adaptation impairments, as well as EOG and ERG disturbances, were detected.
