Weekers, Lavergne, and Prijot (1958), Davenport (I959), and Perkins and Jay (I960) have all commented on a high incidence of myopia in open-angle glaucoma. Abdalla and Hamdi (1970) showed that myopic eyes have higher ocular tensions than emmetropic eyes in most age groups. The findings of Tomlinson and Phillips (1970) agreed with this, but showed that ocular tension correlated more closely with...

OBJECTIVE To describe ocular biometry relationships in older white adults. METHODS Ocular dimensions were measured with partial coherence laser interferometry in 1968 persons (aged 58-100 years, 59% female) seen at the fourth examination of the Beaver Dam Eye Study. Generalized estimating equations-modeled associations of age, sex, height, and education with ocular dimensions: axial length, c...

PURPOSE To investigate the diurnal variation in axial length and anterior eye biometrics, while simultaneously measuring intraocular pressure (IOP) with dynamic contour tonometry in human subjects. METHODS Fifteen young adult near-emmetropic subjects had axial length, anterior eye biometrics (central corneal thickness and anterior chamber dimensions), and IOP measured at six different times a...

PURPOSE To study the 24-hour changes in axial length, lens thickness, and anterior chamber depth in rabbits and to examine the role of ocular sympathetic activity on these changes. METHODS Young adult rabbits were entrained to a daily 12-hour light-12-hour dark cycle. Axial length, lens thickness, and anterior chamber depth were measured using ultrasonic techniques. In the first group of 12 r...

AIMS To evaluate the ocular axial length as a risk factor for development of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). METHODS Ocular axial lengths were measured, by A-scan ultrasonography, in 17 patients with CRVO and 41 patients with BRVO and compared with those of contralateral unaffected eyes and 66 age matched controls. RESULTS In 17 patients with ...

Aims: To study the effect of axial length on the hypotensive effect of latanoprost in primary open angle glaucoma (POAG) in a prospective, observational study. Methods: The authors measured axial length and baseline intraocular pressure (IOP) of 109 eyes with POAG, and then repeated the IOP measurements at 1, 3, and 6 months after starting treatment with latanoprost. Results: The mean IOP level...

PURPOSE In chickens, there are circadian rhythms in axial length, choroidal thickness, and intraocular pressure (IOP), the phases of which differ, depending on visual manipulations that alter ocular growth rate. In this study, these same rhythms were sought in the common marmoset, a primate model of eye growth, to establish whether these may play a role in ocular growth regulation across specie...
