<strong>NHMRC</strong> GUIDELINES FOR THE SCREENING, PROGNOSIS, DIAGNOSIS, MANAGEMENT AND PREVENTION OF GLAUCOMA<br />
Glossary of terms<br />
Pulsatile ocular<br />
blood flow<br />
Refraction<br />
Reverse pupillary block<br />
Selective laser<br />
trabeculoplasty<br />
Short-wavelength<br />
automated perimetry<br />
Tonometry<br />
Trabecular meshwork<br />
Trabeculectomy<br />
Visual acuity<br />
Visual field<br />
The indirect assessment of choroidal blood flow by estimating the influx<br />
of blood into the eye during cardiac systole from an evaluation of the<br />
continuous IOP pulse wave.<br />
Clinically, the determination of the refractive errors of an eye, or eyes<br />
(e.g. myopia, hyperopia, astigmatism, anisometropia).<br />
Blockage of the movement of aqueous from the anterior to the posterior<br />
chamber leading to a concave anatomical configuration of the peripheral iris.<br />
Use of a q-switched Nd:YAG laser to target trabecular meshwork<br />
endothelial cells without provoking coagulative necrosis, to improve<br />
aqueous outflow.<br />
A form of automated perimetry that isolates the blue cone mechanism<br />
of the visual system by utilising a two-colour incremental thresholding<br />
technique consisting of a large blue target on a bright yellow background.<br />
A procedure for measurement of the pressure within the eye.<br />
Clinically, tonometry measures the intraocular tension.<br />
The meshwork of connective tissue that is located between the canal of<br />
Schlemm and the anterior chamber, and which is involved in drainage of<br />
aqueous humor from the eye.<br />
Surgical creation of a fistula to allow aqueous outflow from the anterior<br />
chamber to the subconjunctival tissue space, bypassing the trabecular<br />
meshwork/Canal of Schlemm outflow pathway.<br />
The clearness of vision that depends on the sharpness of the retinal image<br />
and the integrity of the retinal and visual pathway. It is expressed as the angle<br />
subtended at the anterior focal point of the eye by the detail of the letter or<br />
symbol recognised.<br />
The area or extent of space visible to an eye in a given position.<br />
