Types of Rare Eye Diseases


Acanthamoeba Keratitis

Causes and Risk Factors:

Acanthamoeba Keratitis is a rare but serious infection of the eye that can lead to permanent vision loss or blindness. It is primarily caused by a microscopic amoeba called Acanthamoeba, which is commonly found in water sources, soil, and air.

  • Water Exposure: People who use contact lenses are particularly at risk, especially if they have a history of exposing their lenses to water, including swimming or showering while wearing lenses.
  • Poor Hygiene: Inadequate cleaning of contact lenses and cases increases the risk of infection.
  • Eye Injury: A prior injury or damage to the eye can make it more susceptible to infection.


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.


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.

  • Medication: Corticosteroid eye drops to reduce inflammation and immunosuppressive drugs to manage the underlying condition.
  • 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.


  • 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.
  • Adaptive Devices: Currently, there is no cure; treatment focuses on managing symptoms using visual aids and adaptive devices.

Quote from a Specialist: “Stargardt Disease often goes unnoticed until noticeable vision loss occurs. Early detection, though challenging, can significantly enhance the management of the condition, focusing on adapting to the visual impairments and improving the quality of life,” says Dr. Jane Foster, an ophthalmologist specializing in rare eye disorders.

Other and Additional Rare Eye Diseases

Overview of Additional Rare Eye Diseases:

There are numerous other rare eye diseases, each with unique symptoms, causes, and treatment approaches. Some of these include:
