Difference between Glaucoma and Cataract: Understanding Eye Health
When it comes to eye health, two common conditions that people often hear about are glaucoma (a condition affecting the optic nerve) and cataracts. Each condition has a noticeable impact on vision, but they are quite different in terms of their development, symptoms, and treatment methods. In this blog, we’ll dive into the distinct characteristics between these two conditions, so you can better understand their effects.

Overview
Glaucoma is an eye condition where increased pressure within the eye damages the optic nerve, which can cause vision loss over time. This serves as a primary glaucoma vs cataracts difference.

Cataract is the gradual clouding of the eye's natural lens, which leads to overall blurry vision. The difference between glaucoma and cataracts lies in how each affects the eye and vision.

Vision Impact
In glaucoma, vision loss often begins at the edges of the visual field, progressing towards tunnel vision or, in severe cases, blindness.

For cataracts, general vision cloudiness, making clear sight difficult. This represents a notable difference between glaucoma and cataracts distinction.

Types of Glaucoma vs. Types of Cataract
Types of Glaucoma
Types of Cataract
Open-Angle Glaucoma - The leading glaucoma type where the drainage channels slowly clog, causing a rise in eye pressure.

Nuclear Cataract click here - Located at the lens center, often linked with aging, causing the lens to harden more info and yellow.

Angle-Closure Glaucoma - Sudden drainage angle closure between iris and cornea, requiring emergency attention.

Treatment for Cataracts
Managing Glaucoma

Glaucoma is treated by lowering eye pressure through like medicated drops, laser treatments, and surgery. Vision loss from glaucoma cannot be reversed.

Cataract can be corrected by replacing the lens, restoring sight. Glaucoma and cataracts require distinct treatments.
