What falls under Cornea Services?

Key Takeaways: The cornea is critical to vision, and specialised cornea services focus on diagnosing and treating conditions affecting its clarity and structure Corneal diseases range from infections and injuries to genetic and degenerative conditions that can significantly affect vision if untreated Corneal conditions are classified into surface disorders, infections, dystrophies, ectatic disorders, and injuries Infections, ageing, surgery, genetics, contact lens misuse, trauma, systemic illness, and environmental exposure can all damage the cornea Pain, redness, blurred vision, tearing, light sensitivity, and corneal scarring are key signs of corneal disease Good eye hygiene, proper contact lens care, and avoiding exposure to infections help reduce the risk of corneal conditions Early diagnosis enables effective management through medications, vision correction, or advanced surgical procedures, including corneal transplants

To understand what falls under corneal services, let’s first understand what is cornea and why is it crucial for eye health? 

The cornea is the transparent, dome-shaped layer at the front of the eye and is often referred to as the window of the eye. Despite its delicate nature, it plays a vital role in vision, contributing nearly two-thirds of the eye’s total focusing power. It consists of three main layers: epithelium, stroma, and endothelium. Any damage, infection, or degeneration to these layers can significantly impair vision and eye comfort. In this blog, we will explore common corneal diseases, their causes and symptoms, and the range of specialised corneal services used to diagnose and manage these conditions effectively.

An overview of corneal diseases

The cornea can be damaged due to a wide range of conditions, including infections related to contact lens use, traumatic abrasions, and inflammatory disorders. Common corneal diseases include corneal ulcers, keratoconus, pterygium, and Fuchs’ endothelial dystrophy, all of which can impact vision and eye comfort if left untreated. Broadly, corneal diseases can be classified into the following categories:

1. Ocular surface disorders: In this condition, the outermost layers of the cornea and tear film are affected, often causing dryness, irritation, and visual discomfort.
2. Corneal infections: Infections caused by bacteria, viruses, fungi, or parasites that can lead to inflammation, ulcers, and vision loss if left untreated.
3. Corneal dystrophies: Genetic or inherited conditions that cause progressive changes in corneal clarity and structure over time.
4. Corneal ectatic disorders: Disorders such as keratoconus in which the cornea progressively thins and bulges, resulting in distorted vision.
5. Corneal injuries: Damage to the cornea caused by trauma, foreign bodies, or chemical exposure, and often requires immediate medical attention.

What are the common symptoms of corneal diseases?

Corneal diseases can present with a range of symptoms that vary in severity depending on the underlying condition. Some of the most common symptoms include:

1. Pain
2. Redness
3. Blurred vision
4. Tearing
5. Extreme sensitivity to light
6. Corneal scarring

What are the main causes of corneal diseases?

Corneal diseases can develop due to a variety of factors that affect the health, clarity, or structure of the cornea. The most common causes include:

1. Bacterial, fungal, and viral infections: Infections that directly damage corneal tissue and may lead to inflammation, ulcers, or scarring.
2. Age-related changes: Natural ageing processes can gradually affect corneal clarity, thickness, and endothelial function.
3. Cataract or intraocular lens implant surgeries: In some cases, certain surgical procedures may impact corneal health and recovery.
4. Hereditary factors: Genetic conditions that predispose individuals to corneal dystrophies or structural abnormalities.
5. Improper use of contact lenses: Poor hygiene, overuse, or incorrect handling of contact lenses can increase the risk of corneal infections.
6. Eye trauma: Injuries caused by foreign bodies, accidents, or chemical exposure that damage the corneal surface.
7. Certain systemic diseases: Conditions such as diabetes or autoimmune disorders that can indirectly affect corneal health.
8. Environmental factors: Prolonged exposure to dust, pollution, chemicals, or UV radiation that may irritate or damage the cornea.

How to Prevent Corneal Diseases?

Good eye hygiene and timely precautions play a crucial role in maintaining corneal health and preventing avoidable eye conditions. The risk of corneal diseases can be significantly reduced by following a few simple preventive measures:

1. Wash hands thoroughly before touching the eyes or handling contact lenses.
2. Clean hands properly after coming into contact with someone who has an eye infection.
3. Avoid sharing eye makeup, contact lenses, or contact lens solutions with others.
4. Clean, disinfect, and replace contact lenses as recommended by your eye care professional.
5. Avoid close contact with individuals who have contagious eye conditions such as conjunctivitis.

Treatment of Corneal Diseases

In case of a corneal disease, timely treatment is essential to prevent vision loss and long-term complications. Depending on the type and severity of the condition, the following treatment options are opted for by doctors:

• Medications: Antibiotics, antifungals, antivirals, or steroids to control infection and inflammation.
• Corrective support: Prescription glasses or contact lenses to improve vision in early or moderate stages.
• Advanced surgical procedures: These include: a. Lamellar corneal transplant for selective layer replacement, & full-thickness corneal transplant in severe cases. Advanced procedures such as Endothelial Keratoplasty or DSAEK may be used to restore corneal clarity and vision with faster recovery in suitable patients.
• Corneal Collagen Crosslinking (C3R): A technique to strengthen the cornea in cases of corneal ectasia or keratoconus.

Early diagnosis and appropriate intervention significantly improve treatment outcomes.

FAQs:

What causes corneal diseases?

Corneal diseases can be caused by infections, eye injuries, improper contact lens use, genetic conditions, age-related changes, eye surgeries, systemic diseases, and environmental factors such as dust, pollution, or UV exposure.

How to prevent corneal infections?

Corneal infections can be prevented through good eye hygiene, proper contact lens care, regular handwashing, avoiding eye rubbing, not sharing eye cosmetics, and seeking timely treatment for eye irritation or injury.

How to treat corneal infections at home?

Corneal infections should not be treated at home without medical advice. Home care is limited to avoiding eye strain and maintaining hygiene, while proper treatment requires prescribed medications from an eye specialist.
