What Is Corneal Abrasion?

Scratched cornea of the human eye is also known as corneal abrasion. Cornea is a colored protective layer over iris and the pupil. Corneal layer is important for vision, filtration of harmful rays such as intense ultraviolet rays and protection. Corneal injury means injury of epithelial surface of eye (most superficial layer). Abrasion is limited to top most five layers of the cornea. Any dust or sand particles trapped inside the eyelid lead to scratching of cornea. Scratching of cornea leads to pain, heaviness and discomfort. Eye scratching is ranging from small to large abrasion.

What Causes Corneal Abrasion?

What Are the Precautionary Measures?

Sign and Symptoms of Corneal Scratching

Symptoms are present from few minutes to several days.

How Is Corneal Abrasion Diagnosed?

Slit lamp examination and fluorescein instillation is useful to confirm the exact diagnosis. Ocular CT scan and MRI are also useful for large erosions. Corneal ulcer is a one of the complications. Bacterial culture is necessary before instillation of antibiotics.

How to Treat Pain Due to Corneal Scratching?

Purpose for treatment is to reduce pain and complications. Healing takes time. Sometimes healing takes more time and also requires extensive treatment.

Treatment is initiated with removal of contact lenses. Washing of the eyes should be done with cold water for 15 to 20 minutes. If any foreign particles are trapped into eyelids, it will be removed immediately with the help of cotton wool.

Sometimes doctor has to use fine needle to remove or lift particles from the eyes. That time local anesthetics are used to ease the pain. Doctor can easily remove this because eye surface is surprisingly very hard. Minor injury takes only 24 to 48 hours for healing. Deeper tissue scratching causes scarring of cornea and it is treated by corneal transplant.

Local Anesthetics:

It is used for analgesic effects. Anesthetic drugs are Tetracaine and Proparacaine.

  1. Tetracaine - it is used in the form of solution or ointment. It works by blocking of impulses to transmit through restriction of sodium permeability into neuronal membrane. Sodium is an essential part for depolarization (activation of cell). Its effect remains upto 30 minutes. And its effect starts within 1 to 2 minutes. Dose - instill 2 drops in both eyes every 4 hours as required for pain relief.
  2. Proparacaine - it has less irritating property. It works by providing stability to nerve cell through inhibition of initiation and transmission of impulses into cells due to impermeability of essential ions. Its effects start within 20 to 30 seconds after application and remains for a maximum of 20 minutes. Dosage is same as above.

Antibiotic Ointment:

Antibiotic ointments are very useful and first line of treatment in this case. Its usage is different in contact lenses user and non contact lenses users.

1. People Not Wearing Contact Lenses:

2. Contact Lens Wearers:

During treatment, use of contact lens must be avoided strongly.

What Are the Complications After Abrasion?

There are many complications due to eye abrasion such as scarring, fungal ulcers, amoebic keratitis (corneal infection by amoeba), pseudomonas (one type of bacteria) infection, corneal infiltrates or ulcers (local or diffused grayish area with inflammation and edema around cornea).

Even if a person has simple eye injury due to scratching, then he/she should consult an eyecare ophthalmologist within 24 to 48 hours --> https://www.icliniq.com/ask-a-doctor-online/eye-care-ophthalmologist
