Neovascular Age-Related Macular Degeneration

Neovascular age-related macular degeneration (AMD) is a type of eye disease that affects the macula, the part of the retina responsible for central vision. It is characterized by the growth of new, fragile blood vessels under the macula, which can leak fluid and cause damage to the surrounding tissue.

Causes and Risk Factors

The exact causes of neovascular AMD are not fully understood, but it is believed to be related to a combination of genetic and environmental factors. Risk factors for developing neovascular AMD include:

• Age: Neovascular AMD is most common in people over the age of 50.
• Family history: Having a family history of AMD increases the risk of developing the condition.
• Smoking: Smoking has been shown to increase the risk of developing neovascular AMD.
• High blood pressure: High blood pressure may also increase the risk of developing neovascular AMD.

Symptoms

The symptoms of neovascular AMD can vary, but common signs include:

• Distorted vision: Straight lines may appear wavy or curved.
• Blind spots: Blind spots or missing areas of vision may occur.
• Loss of central vision: Neovascular AMD can cause a loss of central vision, making it difficult to perform tasks such as reading or driving.

Diagnosis

Neovascular AMD is typically diagnosed using a combination of the following tests:

• Visual acuity test: This test measures the sharpness of vision.
• Dilated eye exam: This exam allows the doctor to view the retina and macula in detail.
• Fluorescein angiography: This test uses a special dye to highlight the blood vessels in the retina.
• Optical coherence tomography (OCT): This test uses low-coherence interferometry to produce high-resolution images of the retina and macula.

Treatment

Treatment for neovascular AMD typically involves a combination of the following:

• Anti-vascular endothelial growth factor (anti-VEGF) injections: These injections can help reduce the growth of new blood vessels and slow vision loss.
• Laser photocoagulation: This treatment uses a laser to destroy the abnormal blood vessels.
• Photodynamic therapy: This treatment uses a light-sensitive medication and a low-power laser to destroy the abnormal blood vessels.

Prognosis

The prognosis for neovascular AMD varies depending on the severity of the condition and the effectiveness of treatment. With prompt and proper treatment, it is possible to slow vision loss and preserve central vision. However, in some cases, neovascular AMD can lead to significant vision loss or blindness.

Frequently Asked Questions (FAQs)
