Age in angle-closure glaucoma and the normal - a study in profile photography
The British Journal of Physiological Optics
|January 1, 1974
Summary
Age did not correlate with horizontal corneal diameter in normal subjects using profile photography, nor in angle-closure glaucoma patients with either method. Surface photography showed a correlation in normal individuals.
Area of Science:
- Ophthalmology
- Corneal Imaging
- Glaucoma Research
Background:
- Horizontal corneal diameter is a key ocular biometric measurement.
- Previous studies suggest potential age-related changes in corneal dimensions.
- Understanding corneal diameter variations is crucial for diagnosing and managing glaucoma.
Purpose of the Study:
- To investigate the relationship between age and horizontal corneal diameter in normal subjects and those with angle-closure glaucoma.
- To compare corneal diameter measurements obtained by surface photography versus profile photography.
- To assess if axial length influences the age-corneal diameter correlation.
Main Methods:
- Horizontal corneal diameters were measured using surface and profile photography.
- Subjects included normal individuals across different age groups and patients with angle-closure glaucoma.
- Measurements were taken independently of axial length influence.
Main Results:
- A correlation between age and corneal diameter was observed with surface photography in normal subjects.
- This age-corneal diameter correlation was not found using profile photography in normal subjects.
- No significant relationship between age and corneal diameter was detected in angle-closure glaucoma subjects by either method.
Conclusions:
- Profile photography, independent of peripheral corneal opacification, reveals no age-related change in corneal diameter for normal eyes.
- Age does not appear to influence corneal diameter in individuals with angle-closure glaucoma.
- Corneal diameter measurement techniques may yield different age-related findings.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
