Symptoms:

The symptoms of Acanthamoeba Keratitis can be similar to other more common eye conditions, making diagnosis challenging. They include:

• Eye pain and redness
• Blurred vision
• Sensitivity to light
• The sensation of something in the eye
• Excessive tearing or discharge

Diagnosis and Treatment:

Diagnosis typically involves a detailed examination of the eye, laboratory tests, and sometimes, the use of confocal microscopy to identify the presence of amoebae.

• Medication: Intensive topical anti-amoebic therapy is the primary treatment, often requiring hospitalization.
• Surgical Intervention: In severe cases, a corneal transplant may be necessary to restore vision.

Behcet’s Disease

Causes and Risk Factors:

Behcet’s Disease is a rare, chronic condition that causes inflammation of the blood vessels, including those in the eyes. The exact cause is unknown, though genetic and environmental factors appear to play a role.

• Genetic Predisposition: Certain genes are associated with an increased risk of developing Behcet’s.
• Environmental Triggers: Infections or environmental factors may trigger the onset of the disease in genetically predisposed individuals.

Symptoms:

In the eyes, Behcet’s Disease can lead to a condition called uveitis, characterized by inflammation of the eye’s middle layer.

• Eye redness and pain
• Blurred or decreased vision
• Sensitivity to light
• Floaters in the vision

Diagnosis and Treatment:

There is no specific test for Behcet’s Disease; diagnosis is based on clinical criteria involving a combination of symptoms.

• Regular Monitoring: Patients need ongoing care to manage symptoms and prevent complications.

Fact: Behcet’s Disease is more common in countries along the ancient “Silk Road” that extends from the Middle East to Asia, indicating a potential genetic and environmental interplay in its occurrence.

Stargardt Disease

Causes and Risk Factors:

Stargardt Disease is a genetic eye disorder that leads to progressive vision loss, typically starting in childhood or adolescence. It’s caused by mutations in the ABCA4 gene affecting the retina.

• Genetic Mutation: It’s an autosomal recessive disorder, meaning both parents must carry the mutated gene.
• Early Onset: Symptoms often start to appear between the ages of 6 and 20.

Symptoms:

• Gradual loss of central vision
• Difficulty adapting to low light
• Wavy vision
• Blind spots

Diagnosis and Treatment:

• Genetic Testing: Confirms the presence of mutations in the ABCA4 gene.
• Visual Field Tests: Assess the extent of central vision loss.
