Summary

The macula has a very high concentration of photoreceptor cells - the cells that detect light. They send signals to the brain, which interprets them as images. The rest of the retina processes our peripheral, or side vision To explore whether cataract surgery evokes development or relapse of choroidal neovascularization (CNV) in wet age-related macular degeneration (AMD) patients followed for a 1-year postoperative period

Detailed description

Age-related macular degeneration (AMD) is a leading cause of vision loss in adults over the age of 50. AMD causes damage to a small part of the retina responsible for central vision called the macula. When damage to the macula occurs, it typically causes loss of central, detailed vision which results in difficulty with tasks such as reading, driving, threading a needle, or recognizing faces. Phacoemulsification is a modern-day cataract surgery that employs ultrasound energy to emulsify the nucleus, vacuum to catch the nuclear material, and irrigation and aspiration for cortex and viscoelastic removal. It is currently impossible to draw definitive conclusions whether phacoemulsification (PhE) is safe for people with age-related macular degeneration (ARMD). It is not clear if PhE causes the progression of ARMD and affects visual acuity (VA). The purpose was to analyze the possible association of PhE with ARMD progression in the early and late (up to 18 months after surgery) period.
