A chemiluminescent material (Cyalume) was injected into the lacrimal excretory passages of eight normal monkeys (16 eyes). Patency was established by almost instantaneous observation of a yellowish-green glow in the nose and pharynx. No toxic effects of the chemical were noted in any of the monkeys.

Ocular motility complications following intranasal surgery.

The ocular motility problem of two patients following intranasal surgery is examined. The patients were studied by eye movement records and ultrasonography. Surgery in both cases revealed a defect of the medial orbital wall with scar tissue incarcerated in the defect.

A fiber-optics pig-tail probe.

A pig-tail probe with a fiber-optics bundle incorporated within its thickness is described. The instrument is used as is commonly done at present with the standard pig-tail probe. In addition, the fiber-optics bundle delivers cold light to the tip of the probe which has been found very useful for locating the torn ends of a canaliculus, as well as delineating the anatomy of the lacrimal sac.

Biomicroscopical choroidoscopy (uveoscopy) and transillumination gonioscopy.

A fiber optic sleeve that fits over a Goldmann three-mirror lens, as well as an independent cable used in conjunction with the Goldmann lens, are described for transillumination biomicroscopical examination of the anterior chamber angle and the uvea. High-intensity retroillumination is provided to the anterior and posterior segments of the globe without production of heat to the eye. Present clinical uses as well as possible future research with the instruments are discussed.

Optic discoscopy through a miotic pupil.

A technique is described whereby visualization of the posterior pole of the retina is accomplished through a very miotic pupil. The technique is simple and quick to perform. A wide field of view is maintained as well as stereopsis.
