Orbitotonography, the dynamic assessment of orbital tension: 2. Results in patients with orbital disease.

Dynamic orbitotonography was done in 17 patients with Graves' disease, 25 patients with orbital tumours and 15 healthy subjects. The mean orbital pressure for both patient groups was significantly different from that for the healthy subjects at each time interval (p less than 0.001). Healthy patients may be differentiated from those with orbital disease with a good degree of reliability with this technique. As well, the technique may provide information about the location of disease within the orbit.

A microcomputer system for on-line collection of blood flow and related physiological data.

A multi-disciplinary approach is described for the development of a microcomputer based on-line data collection system for blood flow experiments. Well designed software provides a flexible approach to data collection, which is particularly suited to blood flow research laboratories. The choice of well supported hardware ensures ease of development with minimum time and cost.

Miniprobe for lacrimal sac temperature measurement.

The hypodermic probe is presented as a portable and easily used instrument for assessing the temperature within the lacrimal drainage system. Its size makes it practical for clinic or office use. It is also acceptable to the patient and may be performed immediately prior to lacrimal syringings. We suggest that lacrimal sac temperatures may be readily measured and are helpful in assessing the degree of inflammation or the presence of mucus in the lacrimal sac.

Orbitotonography, the dynamic assessment of orbital tension: 1. Results in subjects without known orbital disease.

This paper describes a new orbitotonometer and method of dynamically assessing the orbital tissue resistance ("orbital tension"). In 20 healthy volunteers without known orbital disease the inexpensive instrument proved to be safe and accurate, providing useful, reproducible clinical information. The full diagnostic work-up of patients with orbital disease should include the accurate measurement of orbital tension, as this may provide the ophthalmologist with earlier objective evidence of the disease process as well as a method of following its course.

A spectacle device to treat facial nerve paralysis.

We describe a new method to prevent ocular complications in facial nerve palsy. A device mounted on a spectacle frame senses the blink of the normal eye and closes the lids of the paretic eye by levers which rest on the upper and lower lids. It provides a physiologic replacement of function and prevents corneal exposure.

Equipment maintenance: moving beyond insurance to self-managed programs.

Equipment maintenance insurance is a recent development that has achieved some cost savings for hospitals. However, greater cost savings can be achieved by a centrally managed self-insurance program that crosses departmental lines. The benefits of such programs are further enhanced when they are run by a technical rather than a financial person.
