Purpose Following the recognition, some 80 years ago, that the accommodation of the eye is not stable but fluctuates over a range of about ±0.5 D, mainly at frequencies of up to a few Hz, there has been a continuing interest in the characteristics o

Optic nerve hypoplasia (ONH) is a congenital deficiency of retinal ganglion cells and their axons that form the optic nerve. The condition is associated with visual deficits ranging from no light perception in severe cases, to vision within normal ra

Background. Interocular visual latency differences in patients with traumatic optic neuropathy due to midface injury were compared using both measurements of the delay from the spontaneous Pulfrich effect and pattern visual evoked potentials (VEPs).

Acute alcohol ingestion can change accommodation, but the long term effects of sustained alcohol consumption on accommodative function have not been studied in detail. This study was thus undertaken on individuals with a history of alcohol abuse.Thir

Purpose: To assess repeatability, horizontal heterophoria measurements were taken from 31 subjects on five occasions, each between 1 and 4 weeks apart. Method: Distance heterophoria was measured using a Maddox Rod, and near heterophoria was measured

Purpose: To assess the influence of pupil size on pupil cycling time (PCT), a measure which may be elongated in cases of neurological disease. Method: Clinically, pupil ”cycling” is produced by focusing a slit-lamp beam on the pupil margin. A rhy

The visual acuities of 17 young emmetropes and corrected ametropes were measured over the range of 7.5 – 0.19 m using a Bailey—Lovie chart. Accommodation stimulus—response measures were also taken over this range using retinoscopy to establish

Results from simple colour vision tests used for the detection of the Type III colour vision deficiency in glaucoma and ocular hypertension are presented. We assessed 49 patients with primary open angle glaucoma, 16 ocular hypertensives, 54 age match
