This paper aims to synthesize current findings on the effects of saffron on macular degeneration and assess its viability as a treatment option.

Wet & Dry AMD Types

Understanding Age-Related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a progressive eye condition that affects the macula, the central part of the retina responsible for sharp vision. It primarily affects older adults and is a leading cause of vision impairment among this demographic.

Types of AMD:

Dry AMD:

  • Characterized by the gradual breakdown of light-sensitive cells in the macula. It is more common but progresses slowly. Symptoms include blurred vision and difficulty recognizing faces.

Wet AMD:

  • Involves abnormal blood vessel growth beneath the retina. It progresses rapidly, leading to significant vision loss. Symptoms include dark spots in central vision and straight lines appearing wavy.

Impact on Vision

AMD affects the macula, crucial for tasks requiring detailed vision like reading and driving. Damage to this area results in central vision loss, while peripheral vision usually remains intact.

Role of Drusen Deposits

Drusen are yellow deposits under the retina often found in individuals with AMD. These deposits can be:

  • Small Drusen: Generally harmless but may indicate early signs of AMD.
  • Large Drusen: Associated with a higher risk of progressing to advanced AMD, both dry and wet forms.

Understanding these aspects helps in recognizing AMD's impact and underscores the importance of early detection and intervention.

Recognising Symptoms and Seeking Diagnosis

Identifying the early signs of age-related macular degeneration (AMD) is crucial for managing the disease effectively. Common symptoms include:

  • Blurry or fuzzy vision: Objects may appear out of focus.
  • Dark or empty areas in the centre of vision: These spots can grow over time, making it challenging to read or recognize faces.
  • Distorted vision: Straight lines may appear wavy or bent, a symptom particularly noticeable when looking at grids or patterns.
  • Difficulty adapting to low light levels: Trouble seeing in dimly lit environments.

Regular eye examinations are vital. An eye doctor can detect AMD before significant vision loss occurs. Early diagnosis allows for more treatment options and better management of the condition.

Diagnostic Methods

  • Comprehensive Eye Exam: Includes visual acuity tests and dilated eye exams to inspect the retina and macula.
  • Amsler Grid Test: A simple self-monitoring tool where patients look at a grid pattern to detect any distortions or missing areas in their vision.
  • Optical Coherence Tomography (OCT): Provides detailed images of the retina, revealing any abnormalities or fluid accumulation.
  • Fluorescein Angiography: Involves injecting a dye into the bloodstream to highlight blood vessels in the retina, aiding in identifying abnormal growths.

Early detection through these diagnostic techniques can significantly improve outcomes, emphasizing the importance of regular check-ups with an eye doctor.

Mechanisms of AMD and Saffron's Therapeutic Action

Pathogenesis of AMD AMD develops due to a complex interplay of genetic, environmental, and lifestyle factors. The primary mechanisms involved in AMD include:

  • Oxidative Stress: The retina is highly susceptible to oxidative damage due to its high metabolic rate and exposure to light. Reactive oxygen species (ROS) can damage retinal cells, leading to AMD progression.
  • Inflammation: Chronic inflammation in the retina contributes to AMD development. Inflammatory cytokines and immune responses can damage retinal cells and exacerbate disease progression.
  • Abnormal Blood Vessel Growth: In wet AMD, abnormal blood vessels grow beneath the retina, leading to leakage, bleeding, and scarring, which severely impairs vision.
  • Accumulation of Drusen: Drusen are deposits of extracellular material that accumulate between the retina and the underlying tissue. Large drusen are associated with an increased risk of progressing to advanced AMD.

Saffron's Mechanism of Action 

Saffron's therapeutic potential in AMD is attributed to its bioactive compounds, primarily crocin, crocetin, and safranal. These compounds exhibit several beneficial mechanisms:

  • Antioxidant Properties: Saffron's bioactive compounds scavenge ROS and enhance the activity of antioxidant enzymes. This reduces oxidative damage in retinal cells, mitigating one of the primary factors in AMD progression (Sepahi, Razavi, & Hosseinzadeh, 2018).
  • Anti-inflammatory Effects: Saffron inhibits the expression of inflammatory cytokines and reduces the activation of inflammatory pathways in retinal cells. By curbing inflammation, saffron can potentially slow down the progression of AMD (Sepahi, Razavi, & Hosseinzadeh, 2018).
  • Neuroprotective Effects: Saffron protects photoreceptor cells from apoptosis (programmed cell death) induced by various stressors. This preservation of retinal cells helps maintain retinal function and structure (Sepahi, Razavi, & Hosseinzadeh, 2018).
  • Inhibition of Abnormal Blood Vessel Growth: Saffron's anti-angiogenic properties help prevent the formation of abnormal blood vessels in wet AMD, reducing the risk of leakage and bleeding.

Treatment Approaches

Conventional Treatment Approaches for Wet AMD

Managing wet AMD effectively often relies on targeted medical interventions. Key treatment strategies include:

Anti-VEGF Injections

Anti-VEGF (vascular endothelial growth factor) injections are a cornerstone in treating wet AMD. These injections work by inhibiting the growth of abnormal blood vessels under the retina, which is a hallmark of wet AMD. Commonly used anti-VEGF drugs include:

  • Ranibizumab (Lucentis)
  • Aflibercept (Eylea)
  • Bevacizumab (Avastin)

These medications help to preserve vision and, in many cases, improve it. Administered directly into the eye, anti-VEGF injections are typically given monthly or bi-monthly.

Laser Surgery Techniques

Laser surgery offers another approach to managing wet AMD, primarily focusing on sealing leaky blood vessels. Two main types of laser treatments are used:

  • Photodynamic Therapy (PDT): Involves injecting a light-sensitive drug into the bloodstream, which accumulates in the abnormal blood vessels. A laser then activates the drug to seal these vessels.
  • Thermal Laser Photocoagulation: A high-energy laser is used to directly seal leaky blood vessels. While effective, this technique is less commonly used today due to the risks of damaging surrounding healthy tissue.

Both anti-VEGF injections and laser surgery play crucial roles in preventing further vision loss and maintaining the quality of life for individuals with wet AMD.
