The cornea is the clear front part of the eye covering the iris, pupil, and anterior chamber. Its primary function is to refract, or bend, light to help the eye focus. Given its critical role, any damage or disease affecting the cornea can significantly impact vision.

 In this blog, we will explore common corneal problems, their causes, symptoms, and treatment options to raise awareness and help you maintain optimal eye health.

CORNEAL ABRASIONS

Corneal abrasions are scratches or injuries to the cornea, the transparent front part of the eye that covers the iris, pupil, and anterior chamber. These abrasions can occur due to various reasons and can significantly affect vision and cause discomfort.

Causes:

  • Accidental pokes in the eye
  • Foreign bodies like dust, sand, or metal particles
  • Improper use of contact lenses
  • Vigorous rubbing of the eyes

Symptoms:

  • Severe pain and a gritty sensation
  • Redness and tearing
  • Sensitivity to light
  • Blurred vision

Treatment:

  • Wash the eye with clean water
  • Avoid rubbing the eye
  • Antibiotic eye drops for infections
  • Wear an eye patch to reduce discomfort
  • Seek medical attention if symptoms persist

KERATITIS

Keratitis is the inflammation of the cornea, which can be caused by infections, injury, or underlying conditions.

Causes:

  • Bacterial, viral, fungal, or parasitic infections
  • Wearing contaminated contact lenses
  • Eye injuries
  • Contaminated water exposure

Symptoms:

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

Treatment:

  • Antibacterial, antiviral, or antifungal eye drops depending on the cause
  • Pain relief medications
  • Avoidance of contact lenses until the infection is resolved
  • In severe cases, corneal transplant might be necessary

DRY EYE SYNDROME

Dry eye syndrome occurs when the eyes either do not produce sufficient tears or the tears evaporate too quickly.

Causes:

  • Aging
  • Wind or dry climates
  • Prolonged screen time
  • Certain medications
  • Autoimmune diseases like Sjogren’s syndrome

Symptoms:

  • Stinging or burning sensation
  • Redness and dryness
  • Blurred vision
  • Sensitivity to light
  • Eye fatigue

Treatment:

  • Artificial tears or lubricating eye drops
  • Lifestyle changes
  • Prescription medications to increase tear production
  • Punctal plugs to retain natural tears

CORNEAL ULCERS

c are open sores on the cornea, often resulting from infections or severe dry eyes.

Causes:

  • Bacterial, viral, fungal, or parasitic infections
  • Severe dry eye syndrome
  • Trauma or injury to the eye
  • Contaminated contact lenses

Symptoms:

  • Severe eye pain and redness
  • Excessive tearing or discharge
  • Blurred vision
  • Spot on the cornea in white and grey
  • Sensitivity to light

Treatment:

  • Antibacterial, antiviral, or antifungal eye drops based on the cause
  • Steroid eye drops to reduce inflammation
  • Pain relief medications
  • In severe cases, surgical intervention such as corneal transplant

CORNEAL DYSTROPHIES

Corneal dystrophies are a group of genetic, often progressive, eye disorders in which abnormal material accumulates in the cornea.

Causes:

  • Genetic mutations leading to abnormal protein deposits in the cornea

Symptoms:

  • Blurred vision
  • Sensitivity to light
  • Recurrent eye pain, especially upon waking
  • Glare and halos around lights

Treatment:

  • Regular monitoring by an eye specialist
  • Lubricating eye drops to relieve symptoms
  • Use of therapeutic contact lenses
  • In advanced cases, corneal transplant

KERATOCONUS

Keratoconus is a progressive eye disease in which the cornea thins and bulges into a cone-like shape, distorting vision.

Causes:

  • Genetic predisposition
  • Eye rubbing
  • Down syndrome and connective tissue disorders

Symptoms:

  • Blurred and distorted vision
  • Increased sensitivity to light and glare
  • Frequent changes in eyeglass prescriptions
  • Difficulty with night vision

Treatment:

  • Eyeglasses or soft contact lenses in early stages
  • Rigid gas-permeable contact lenses for more advanced cases
  • Corneal cross-linking to strengthen corneal tissue
  • Intacs (corneal implants) to flatten the cornea
  • Corneal transplant in severe cases

PTERYGIUM

Pterygium is a benign growth of the conjunctiva that extends onto the cornea, often related to UV exposure.

Causes:

  • Prolonged exposure to UV light
  • Dust and wind exposure
  • Dry eye conditions

Symptoms:

  • Redness and irritation
  • Foreign body sensation
  • If the growth extends over the cornea reflects as blurred vision.
  • Cosmetic concerns

Treatment:

  • Lubricating eye drops to reduce irritation
  • UV-protective eyewear to prevent progression
  • Surgical removal in cases where vision is affected

  • Follow the recommended schedule for regular eye exams, especially if you have existing eye conditions or risk factors.

Manage Underlying Health Conditions:

  • Control chronic conditions like diabetes and hypertension, which can affect eye health.
  • Address autoimmune disorders and seek appropriate treatment.

Stay Hydrated and Maintain a Healthy Diet:

  • Water intake is essential to keep your eyes hydrated.
  • Consume a diet rich in vitamins and minerals essential for eye health, such as vitamins A, C, and E, and omega-3 fatty acids.

Avoid Eye Strain:

  • Take breaks if we using screen for a long time
  • Must practice 20-20-20 rule

Medical Advice

The cornea plays a crucial role in our vision, and any problems affecting it can significantly impact our quality of life.
