Summary
Globe protrusion decreases linearly with age in Caucasian adults aged 31-80. This age-related change in ocular protrusion shows no significant difference between sexes or eyes.
Area of Science:
- Ophthalmology
- Gerontology
- Anatomy
Background:
- Orbital aging is a complex process.
- Understanding changes in ocular structures with age is crucial for clinical assessments.
- Globe protrusion is a key indicator of orbital volume and soft tissue dynamics.
Purpose of the Study:
- To determine the age-related pattern of globe protrusion.
- To provide data for longitudinal assessment in patients with orbital conditions.
- To enhance understanding of orbital aging processes.
Main Methods:
- Measured ocular protrusion in 653 healthy Caucasian adults (ages 21-80).
- Excluded individuals with ocular or orbital diseases.
- Analyzed data for sex and eye laterality, using a single observer and instrument.
Main Results:
- Mean exophthalmometry reading was 19+/-2mm.
- A significant negative linear correlation was found between ocular protrusion and age (r=0.56-0.65, p<0.0001).
- No significant difference in age-related protrusion changes between sexes or eyes; asymmetry did not increase with age.
Conclusions:
- Ocular protrusion significantly decreases linearly with age in Caucasians aged 31-80.
- Age-related changes in globe protrusion are consistent between sexes and eyes.
- Findings are valuable for assessing orbital aging and managing related pathologies.

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
01:27Gravity between Spherical Bodies
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...
