Ocular Surface Damage
Understanding Eye Injuries Caused by Chemicals
Understanding Chemical Injury to the Eye: A Patient Guide
Chemical injury to the eye occurs when the eye comes into contact with harmful substances such as acids, alkalis, or other chemicals. These injuries can cause significant damage to the delicate structures of the eye, including the cornea, conjunctiva, and surrounding tissues. Here’s what you need to know
Types of
Chemical Injuries
Acid Burns
Caused by acids such as sulfuric acid or hydrochloric acid, resulting in coagulative necrosis and tissue destruction.
Alkali Burns
Caused by alkaline substances like lye or ammonia, leading to liquefactive necrosis and deeper tissue penetration.
Causes of Ocular Surface Chemical Injuries
Accidental exposure to household cleaning products, industrial chemicals, or environmental hazards.
Mishandling of chemicals during work or leisure activities.
Acts of violence or assault involving chemical substances.
Symptoms That May Indicate Chemical Eye Injury
Chemical exposure can cause sudden burning pain and intense discomfort immediately after contact with the eye.
The eye may appear extremely red due to irritation and inflammation of the ocular surface.
The eye often produces excessive tears as a protective response to wash out the chemical substance.
Chemical injury may temporarily or permanently affect vision depending on the severity of corneal damage.
Many patients experience discomfort while looking at bright light due to irritation and inflammation inside the eye.
Treatment For Chemical Injury
Amniotic Membrane Transplantation (AMT) Surgery
What is Amniotic Membrane Transplantation?
Amniotic membrane transplantation (AMT) is a surgical procedure that involves the use of the amniotic membrane (the innermost layer of the placenta) to repair or regenerate the ocular surface. The amniotic membrane has unique properties that make it ideal for this purpose: it is anti-inflammatory, anti-fibrotic, anti-scarring, and promotes epithelial healing. It is used in various ophthalmic conditions to enhance wound healing and reduce inflammation.
Indications for AMT in Eye Surgery
AMT is indicated in several ocular conditions, particularly those involving the cornea and conjunctiva. These include
To manage acute stages and support ocular surface healing.
To prevent or treat adhesion between the eyelid and the eyeball.
For reconstructing the conjunctival surface in cases of scarring or cicatrization.
To provide tectonic support and promote healing.
As part of treatments for limbal stem cell deficiency, such as SLET (Simple Limbal Epithelial Transplantation).
To promote healing and reduce inflammation in cases of chemical injury to the eye.
To manage and heal the ocular surface after burns caused by heat.
Particularly those that are refractory to conventional treatments, to aid in healing and prevent perforation.
When the corneal epithelium fails to heal on its own, AMT can facilitate closure.
To reduce recurrence and enhance healing after the surgical removal of a pterygium.
Procedure
The procedure for AMT involves several key steps
Advantages of AMT
The amniotic membrane provides a scaffold that supports cell growth and tissue regeneration.
By reducing fibrosis, AMT helps maintain the clarity and function of the cornea and conjunctiva.
Its anti-inflammatory properties help manage inflammation and reduce scarring.
The membrane is safe for use on the eye surface and is usually comfortable for patients during the healing process.
Conclusion
Amniotic membrane transplantation is a versatile and effective surgical technique for treating various ocular surface disorders. It offers significant benefits in terms of promoting healing, reducing inflammation, and preventing scarring. If you have any ocular surface conditions that might benefit from AMT, please consult Dr. Arpit Shah at Shriram Super Speciality Eye Hospital.

Simple Limbal Epithelial Transplantation (SLET) Surgery
What is SLET Surgery?
Simple Limbal Epithelial Transplantation (SLET) is a surgical technique used to treat limbal stem cell deficiency (LSCD). The limbus is the border area between the cornea and the sclera, and it contains stem cells essential for the regeneration and repair of the corneal epithelium. In LSCD, these stem cells are damaged or destroyed, leading to a range of ocular problems, including corneal opacity, neovascularization, and vision loss.
Indications for SLET Surgery
- Chemical or Thermal Burns
- Infectious Diseases
- Autoimmune Disorders
- Surgical Trauma
- Congenital Aniridia
Procedure
SLET surgery involves the following steps
Advantages of SLET Surgery
Minimally Invasive
Requires only a small biopsy of donor tissue, reducing the risk to the donor eye.
Effective for Unilateral LSCD
Particularly beneficial for patients with unilateral disease, as the healthy eye can serve as the donor.
Simple Technique
Does not require complex laboratory facilities or extended cultivation of stem cells.
High Success Rate
Demonstrated to be effective in restoring corneal clarity and improving vision in many cases.
Conclusion
SLET surgery is a promising and effective treatment for limbal stem cell deficiency, offering a simpler and less invasive alternative to other transplantation techniques. It leverages the patient’s own stem cells to promote healing and restore vision, making it a valuable option in the management of LSCD.
