Glaucoma: Overview

Glaucoma: 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...

Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Anatomy of the Eyeball

Anatomy 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...

Area of Science:

Ophthalmology
Biomaterials Science
Drug Delivery

Background:

Intravitreal drug delivery is key for posterior eye diseases.
Vitreous humor properties change with age, affecting drug efficacy.
Limited research connects vitreous changes to therapeutic outcomes.

Approach:

Comprehensive literature review of Scopus, PubMed, and Web of Science up to March 2022.
Analysis of vitreous humor's biological composition and biomechanical properties.
Examination of methods for studying vitreous properties and their changes.

Key Points:

Vitreous humor's composition and biomechanical characteristics are vital.
Age-related changes like liquefaction and shrinking impact drug distribution.
Understanding these dynamics is essential for optimizing intravitreal drug delivery systems.

Conclusions:

Vitreous humor properties and their age-related alterations directly influence intravitreal drug delivery.
Further research is needed to fully grasp how changing vitreous properties affect therapeutic efficacy.
This knowledge gap must be addressed for improved treatment of posterior eye diseases.
