What is Bullous Keratotherapy?

A corneal condition known as bullous keratopathy is typified by corneal swelling (edema) and blisters filled with fluid (bullae). It happens when the cornea's endothelial cells, which remove extra fluid to preserve corneal clarity, are harmed or malfunction. This causes fluid to build up in the cornea, which impairs vision and causes pain and discomfort.

What are the Common Symptoms of Bullous Keratopathy?

  • Cloudy or blurry vision brought on by corneal edema.
  • Discomfort or soreness in the eyes that frequently gets worse under bright light.
  • A feeling of grit in the eye or a foreign body.
  • Heightened light sensitivity (photophobia).
  • Eyes that are watery (too much crying).
  • Formation of blisters on the cornea called bullae, which are packed with fluid and can potentially burst, causing excruciating agony.

Causes and Risk Factors of Bullous Keratopathy

Causes

  • Fuchs' Endothelial Dystrophy is a degenerative disorder that weakens the endothelial cells in the cornea.
  • Complications of Eye Surgery: Endothelial cell damage can result during intraocular lens implantation, corneal transplants, or cataract surgery.
  • Eye Trauma or Injury: Endothelial cell dysfunction may be brought on by direct corneal injury.
  • Extended Eye Inflammation: Corneal health may be impacted by chronic uveitis or other inflammatory diseases.

Risk Factors

  • Due to the expected loss of endothelium cells, aging is more prevalent in older persons.
  • Prior Eye Surgery: Individuals with several eye surgeries are more vulnerable.
  • Underlying Eye Diseases: Bullous keratopathy is more likely to occur in people with glaucoma, corneal dystrophies, or infections.
  • Extended Use of Contact Lenses: Inappropriate use of contact lenses can lead to ocular stress and injury.

Latest Research and Technologies in the Treatment of Bullous Keratopathy in Singapore

Bullous keratopathy treatment in Singapore has advanced significantly, with methods such as Descemet Membrane Endothelial Keratoplasty (DMEK) enhancing recovery times and visual results. For severe cases, researchers are also looking into intrastromal amniotic membrane transplantation as a means of symptom relief. Although phototherapeutic keratectomy (PTK) is becoming more popular, Singapore is still assessing whether to use it. Furthermore, the efficacy of novel therapies such anterior stromal puncture (ASP) and corneal collagen cross-linking (CXL) in treating corneal edema is being investigated.

Treatment options for Bullous Keratopathy

Cornea Transplant: Bullous keratopathy is commonly treated with a corneal transplant (keratoplasty). The degree of endothelial degradation impacts the possibility of a corneal transplant.


Cost Start From USD 13000 - USD 27000Explore Options

Comprehensive eye examinations are performed to determine Corneal thickness, endothelial cell activity, and disease severity by using:

  • Slit-Lamp Biomicroscopy, Corneal Pachymetry
  • Optical Coherence Tomography (OCT)
  • Specular Microscopy

As such, there is no rehabilitation. Although rehabilitation therapy does not yet exist, myopia can be improved by following these guidelines:

  • Lifestyle Modifications: Engaging in outdoor activities, limiting screen time, and adhering to the 20-20-20 rule promote eye health.
  • Vision therapy: Eye exercises and strategies to enhance concentration and lessen strain

It is being researched to encourage endothelial cell regeneration, while hypertonic saline eye drops or ointments aid in reducing corneal edema. Additionally, anti-inflammatory drugs and painkillers may be administered to treat discomfort.

Frequently Asked Questions

Bullous Keratopathy does not always require surgery because mild instances can be treated with bandage contact lenses, hypertonic saline drops, and pain and swelling-relieving drugs. However, surgical treatments such as DMEK, DSAEK, or keratoprosthesis can be required to restore vision and alleviate discomfort in extreme situations.

In Singapore, bullous keratopathy is rather common, especially in older individuals and those who have had corneal surgery or cataract surgery in the past. It is a major contributor to corneal edema and frequently necessitates cutting-edge procedures like corneal transplants or endothelial keratoplasty.

A thorough examination of bullous keratopathy is necessary to determine the extent of endothelial cell destruction and corneal edema. To identify the optimum course of treatment and avoid consequences like vision loss or corneal scarring, it uses sophisticated diagnostic techniques like slit-lamp examination, specular microscopy, optical coherence tomography (OCT), and pachymetry.

Untreated Bullous Keratopathy can result in recurring blisters, corneal scarring, severe vision impairment, chronic pain, and possibly corneal ulceration or infection. A whole corneal transplant (PKP) may be necessary to restore eyesight.

To ensure a seamless experience for patients from abroad, most hospitals in Singapore offer the following:

  • Assistance in obtaining visas.
  • Airport Service to and from the hospitals.
  • Multilingual experts and the Best accommodation services.
  • Personalised treatment plans for patients from abroad.
