Photoreceptor degeneration refers to the progressive loss of photoreceptor cells in the retina, leading to impaired vision and potentially blindness. This condition is a hallmark of various retinal diseases, including retinitis pigmentosa and age-related macular degeneration, and involves complex genetic and environmental factors.

Hallmark of various retinal diseases

Retinal diseases encompass a range of conditions that affect the retina, the light-sensitive tissue at the back of the eye, potentially leading to vision impairment or blindness. Early detection and treatment are crucial in managing these diseases, with advancements in medical imaging and therapies offering promising outcomes.

Retinal Diseases

Retinitis Pigmentosa is a group of rare, genetic disorders that involve a breakdown and loss of cells in the retina, leading to progressive vision loss. It typically starts with difficulty seeing at night and a loss of peripheral vision, potentially advancing to tunnel vision and, in some cases, blindness.

Retinitis Pigmentosa

Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults, characterized by the deterioration of the macula, the central part of the retina responsible for sharp vision. While it doesn't lead to complete blindness, AMD significantly impacts the ability to perform everyday tasks that require fine visual detail, such as reading and driving.

Age-related Macular Degeneration

Complex genetic factors

Environmental factors encompass all external elements influencing living organisms, including physical, chemical, biological, and social components. These factors shape ecosystems and human health, driving adaptation and evolution, and are critical in assessing ecological and public health risks.
