Radius of curvature of the posterior surface of the cornea (1997)
Journal Article
Garner, L., Owens, H., Yap, M., Frith, M., & Kinnear, R. (1997). Radius of curvature of the posterior surface of the cornea. Optometry and Vision Science, 74(7), 496-498

The radius of curvature of the posterior surface of the cornea was measured in the vertical meridian for 120 children aged 6 to 17 years, using a Purkinje image method. The mean radius of curvature (+/-SD) was 6.42 +/- 0.31 mm, with a range from 5.62... Read More about Radius of curvature of the posterior surface of the cornea.

An evaluation of the keratoconic cornea using computerised corneal mapping and ultrasonic measurements of corneal thickness (1996)
Journal Article
Owens, H., & Watters, G. (1996). An evaluation of the keratoconic cornea using computerised corneal mapping and ultrasonic measurements of corneal thickness. Ophthalmic and Physiological Optics, 16(2), 115-123. https://doi.org/10.1046/j.1475-1313.1996.95000178.x

Reports indicate the presence of up to three independent cone shapes in keratoconus (round/oval/global) but the preponderance of one cone over another is unclear. This work evaluates keratoconic corneal topography and corneal thickness using videoker...

Keratoconus in monozygotic twins in New Zealand (1995)
Journal Article
Walters, G. A., Owens, H., & Watters, G. (1995). Keratoconus in monozygotic twins in New Zealand. Clinical and Experimental Optometry, 78(4), 125-129. https://doi.org/10.1111/j.1444-0938.1995.tb00805.x

We report on a case of keratoconus in identical twins who were brought up in Christchurch, New Zealand. Videokeratoscopy using an EyeSysa (EyeSys Laboratories, Houston, Texas, USA) revealed not only marked differences in severity of keratoconus betwe...

Pharmacological effects on accommodative adaptation (1992)
Journal Article
Gilmartin, B., Bullimore, M., Rosenfield, M., Winn, B., & Owens, H. (1992). Pharmacological effects on accommodative adaptation. Optometry and Vision Science, 69(4), 276-284

We review the research which has attempted to determine whether the characteristics of autonomic innervation of ciliary smooth muscle are relevant to the process of accommodative adaptation. The effect of various topical autonomic drugs on the three... Read More about Pharmacological effects on accommodative adaptation.

The frequency characteristics of accommodative microfluctuations for central and peripheral zones of the human crystalline lens (1990)
Journal Article
Winn, B., Pugh, J., Gilmartin, B., & Owens, H. (1990). The frequency characteristics of accommodative microfluctuations for central and peripheral zones of the human crystalline lens. Vision Research,

Temporal variations in the nominally steady-state accommodation response can be characterized approximately by two principal regions of dominant activity: a low frequency region (LFR less than 0.6 Hz) and a high frequency region (HFR greater than 1.0...

The effect of pupil size on static and dynamic measurements of accommodation using an infra-red optometer (1989)
Journal Article
Winn, B., Pugh, J., Gilmartin, B., & Owens, H. (1989). The effect of pupil size on static and dynamic measurements of accommodation using an infra-red optometer. Ophthalmic and Physiological Optics,

The study examines to what degree the output of the Canon Auto-ref R1 infra-red (IR) optometer is affected by variations in pupil size for both static measurement of refractive error and for continuous recording of accommodation when switched to its...

THE INFLUENCE OF AGE ON THE FRAGILITY OF THE CORNEA (1984)
Journal Article
MILLODOT, M., & OWENS, H. (1984). THE INFLUENCE OF AGE ON THE FRAGILITY OF THE CORNEA. Acta Ophthalmologica, 62(5), 819-824. https://doi.org/10.1111/j.1755-3768.1984.tb05810.x

Corneal fragility was measured with the Cochet‐Bonnet aesthesiometer on 171 eyes of various ages. It was found to remain the same until about age 40. It increased significantly and progressively afterwards. It was compared to corneal sensitivity whic... Read More about THE INFLUENCE OF AGE ON THE FRAGILITY OF THE CORNEA.

SENSITIVITY AND FRAGILITY IN KERATOCONUS (1983)
Journal Article
MILLODOT, M., & OWENS, H. (1983). SENSITIVITY AND FRAGILITY IN KERATOCONUS. Acta Ophthalmologica, 61(5), 908-917. https://doi.org/10.1111/j.1755-3768.1983.tb01473.x

38 persons with various degrees of keratoconus were examined. Using the photokeratoscope an index of the severity of the cone was established and compared to a group of normal eyes. Sensitivity was measured in the centre and periphery of the cornea.... Read More about SENSITIVITY AND FRAGILITY IN KERATOCONUS.
