Glenoid labrum
The ring of fibrocartilaginous tissue around the glenoid cavity on the scapula. It deepens and increases the congruency of the articulating surface.

Gleason’s score
A measure of the cellular differentiation of prostate cancers that uses the microscopic appearance of biopsied tissue to determine the tumor grade and stage. This is a method used to classify prostate cancer cells in order to identify the most suitable treatment and predict the patient’s prognosis. Multiple tissue samples are collected and each is…

Secondary glasses
Glaucoma caused by ocular trauma or an underlying disease that affects the eye.
-
Primary open-angle glasses
The most common type of glaucoma. It usually affects both eyes, and there is a characteristic change in the appearance of the optic disk. The cup (the depression in the center of the disk) is enlarged. Visual loss is determined by the visual field test. Many patients with glaucoma have increased intraocular pressure but this…
-
Pigmentary glasses
Glaucoma produced by the dispersion of organic pigment from the zonula ciliaris to the trabecular meshwork of the eye.
-
Low tension glasses
A type of glaucoma in which intraocular pressures are normal (less than 22 mm Hg).
-
Closed-angle glasses
Glaucoma caused by a shallow anterior chamber and thus a narrow filtration angle through which the aqueous humor normally passes. Because the rate of movement of the aqueous humor is impaired, intraocular pressure increases. In general, headache, haloes around single sources of light, blurred vision, and eye pain are symptomatic.
-
Chronic glasses
Glaucoma in which the tonometer indicates an intraocular pressure reading of up to 45 or 50, the anterior ciliary veins are enlarged, the cornea is clear, the pupil is dilated, and pain is present. During attacks vision is poor. The visual field may be normal. Cupping of the optic disk is not present in the…
-
Absolute glasses
An extremely painful form of glaucoma in which the eye is completely blind and hard as stone (as a result of elevated intraocular pressures) with an insensitive cornea, a shallow anterior chamber, and an excavated optic disk.

Prism glasses
An optical device, used by persons who must lie supine for extended periods, to allow them to view objects in their environment without eye or neck strain. Prisms mounted on spectacle frames bend the image to make the feet visible while the person is looking straight ahead.
