Can eyes recover from chemical burns?

 



Restoring a normal ocular surface and corneal clarity after chemical harm is the aim of treatment. Limbal stem cell grafting, amniotic membrane transplantation, and perhaps keratoprosthesis can be used to assist restore eyesight if there is severe corneal scarring.

When the eye or eyelid is exposed to a chemically corrosive substance, such as an acid or alkaline, a chemical eye burn happens. Although chemical burns make up 5% of all burn injuries, only 7–10% of those chemical burns include the eyes, according to WebMD. Chemical eye burns, on the other hand, are regarded as ophthalmological emergency when they happen.

Chemical Eye Burn Causes:

Most chemical eye injuries happen on the work. Several chemicals are regularly used in industries. Yet, chemical injuries from cleaning supplies or other common household items also happen often at home; these injuries can be just as deadly and need to be handled properly and right away.

Alkali burns, acid burns, and irritants are the three main types of chemical eye burns.

Alkaline burns: An alkaline substance measures from eight to fourteen on a pH (power of hydrogen) scale, with seven being neutral. An acid measures from zero to six on this scale. The category of the strongest alkaline compounds is 14; the greater the number, the stronger the base. Among of the most popular alkaline chemical burn agents are sodium hydroxide, potassium hydroxide, and calcium hydroxide. Alkaline compounds are made of soluble hydroxides, including lithium, potassium, and sodium. Cement, fertilisers, hair dye, hair relaxers, and other items for cleaning both inside and outside the home all include these substances.

Acid burns: The number indicates the strength of the acid, with one representing the strongest acids. Hydrochloric acid, sulfuric acid, formic acid, hydrofluoric acid, and chromic acids are some of the most often used acid burn agents. These substances are present in laboratories, cleaning supplies, manufacturing facilities, industrial plants, batteries, etc.

Symptoms of chemical burns to the eye:

The symptoms of a chemical burn depend on the substance splashed into the eyes, but may include:

  • Stinging
  • Pain
  • A burning sensation
  • Blurry vision
  • Watery eyes.
  • Redness

·        Complications of chemical burns to the eye

Complications of severe chemical burns can include:

  •          Corneal ulcer – superficial damage to the cornea
  •          Corneal perforation – full thickness damage to the cornea, the clear surface of the eye
  •          Retinal damage
  •          Loss of the eye
  •          Cataracts – an abnormal clouding of the eye’s lens
  •          Glaucoma – high pressure within the eye, which damages the optic nerve.

Treatment for chemical burns to the eye

  • Treatment differs according to the chemical agent and the severity of the injury, but may include:
  •  Pain-relieving medication
  • Medicated eye drops
  • Topical antibiotics to reduce the risk of infection
  • Anti-inflammatory medication
  • Lubricants applied to the eye surface to prevent the eyelids from sticking to the cornea as it heals
