When it comes to eye health, it’s easy to get lost in a maze of confusing terminology. “Pavingstone degeneration” and “cobblestone degeneration” are two such terms that often cause head-scratching. While they sound similar, these conditions affect the eyes in different ways. Retina and Vitreous Surgeons of Utah sheds some light on their key distinctions below.
What is Pavingstone Degeneration?
This degenerative condition affects the outer edges of your vision, known as the peripheral retina. Essentially, the retinal pigment epithelium (RPE), a layer of cells that nourishes your retina, begins to thin and deteriorate. This process creates a distinctive pattern on the retina.
- Appearance: Imagine a road paved with flat stones – that’s what this condition resembles. It involves the peripheral retina (the outer edges of your vision) where small, yellow-white patches develop.
- Cause: Typically age-related, pavingstone degeneration occurs when the retinal pigment epithelium (RPE) – a layer of cells nourishing the retina – thins and deteriorates.
- Complications: Generally harmless and doesn’t affect central vision. Rarely, it may lead to retinal tears or detachments.
What is Cobblestone Degeneration?
Unlike pavingstone degeneration, this condition is usually present at birth. During fetal development, a structure called the embryonic fissure may not close completely, leading to small gaps in the peripheral retina.
- Appearance: This condition, also known as “peripheral retinal holes,” presents as small, round holes clustered in the peripheral retina, resembling a cobblestone street.
- Cause: Often congenital (present at birth), it arises from incomplete closure of the embryonic fissure during fetal development.
- Complications: Usually asymptomatic, but in rare cases, can lead to retinal detachments.
Key Differences Between Pavingstone and Cobblestone Degeneration
- Location: Both primarily affect the peripheral retina.
- Origin: Pavingstone degeneration is often age-related, while cobblestone degeneration is usually congenital.
- Appearance: Pavingstone presents as flat, yellow-white patches; cobblestone appears as small holes.
- Risk: Both carry a small risk of retinal complications.
What to Do
If you experience any changes in your vision, including flashes, floaters, or a curtain-like shadow, consult an eye doctor immediately. Regular comprehensive eye exams are crucial for early detection and management of any retinal condition.
