Rising Concerns Over Keratoconus Cases in Sri Lanka
Sri Lanka is witnessing a concerning increase in cases of keratoconus, a progressive eye disorder that affects vision. The National Eye Hospital has recently issued a warning about the growing prevalence of this condition, which is now being detected in children as young as eight years old.
On World Keratoconus Day, which was observed on November 10, Dr. Kusum Ratnayaka, a Consultant Cornea Surgeon at the hospital, addressed the media and shared critical insights into the condition. He emphasized that while keratoconus typically begins during teenage or early adult years, it is now being diagnosed in younger patients, raising alarms among medical professionals.
Dr. Ratnayaka pointed out that most individuals affected by keratoconus fall within the age range of 10 to 40. However, the early onset in children highlights the need for increased vigilance and timely intervention.
Risk Factors and Causes
The doctor explained that several factors can increase the risk of developing keratoconus. These include:
- A family history of the condition
- Frequent eye rubbing
- Allergic eye conditions such as vernal keratoconjunctivitis
- Certain genetic disorders like Down syndrome
- Connective tissue diseases
He stressed the importance of identifying these risk factors early, as they can contribute to the progression of the disease. Early screening and public awareness are essential in preventing severe complications.
Impact on Vision and Treatment Options
Keratoconus is characterized by a gradual thinning and bulging of the cornea, causing it to take on a cone-like shape. This distortion leads to blurred and distorted vision, significantly impacting daily activities and quality of life.
Dr. Ratnayaka outlined the various treatment options available, depending on the stage and severity of the condition:
- In the early stages, spectacles or specialized contact lenses may be prescribed to correct vision.
- For more advanced cases, corneal collagen cross-linking is used to strengthen the cornea and halt further progression.
- In severe instances, corneal transplants may be necessary to restore vision.
He warned that untreated keratoconus can lead to serious vision impairment, underscoring the importance of seeking medical attention promptly.
The Need for Awareness and Education
Public awareness campaigns play a crucial role in addressing the rising number of keratoconus cases. By educating communities about the symptoms, risk factors, and available treatments, healthcare providers can encourage early detection and timely management.
Dr. Ratnayaka called for greater efforts to raise awareness, particularly among parents and educators, who can play a key role in identifying early signs of the condition in children.
Conclusion
As the incidence of keratoconus continues to rise, it is vital for individuals, especially those with known risk factors, to seek regular eye examinations. With proper care and treatment, many patients can maintain good vision and prevent long-term complications. The National Eye Hospital remains committed to providing comprehensive care and support for those affected by this challenging condition.
