Condition

What Is Glaucoma?

Glaucoma refers to a group of eye conditions that damage the optic nerve, typically due to increased pressure within the eye. This damage can lead to irreversible vision loss and, if left untreated, may result in blindness.

Origins

Causes of Glaucoma

The exact cause of glaucoma is not entirely understood, but several factors may contribute, including:

Increased Intraocular Pressure

The main factor contributing to optic nerve damage is elevated pressure within the eye (intraocular pressure), but glaucoma can also occur without elevated pressure.

Optic Nerve Damage

The exact reason behind optic nerve damage in glaucoma is not fully understood, but it's believed to be related to poor drainage of fluid (aqueous humor) from the eye.

Age, Genetics, and Other Factors

Advanced age, a family history of glaucoma, certain medical conditions (like diabetes or high blood pressure), and prolonged use of corticosteroids might increase the risk.

Diagnosis

Symptoms of Glaucoma

Gradual Vision Loss

Often, glaucoma progresses slowly, causing a loss of peripheral vision initially, which can go unnoticed until later stages.

Blurred Vision

Vision might appear hazy or blurry even with corrective lenses.

Halos Around Lights

Seeing halos around lights, especially in low light conditions.

Severe Eye Pain or Headache

Acute angle-closure glaucoma can cause sudden and severe eye pain, accompanied by nausea, vomiting, and headaches.

Glaucoma Treatment

Glaucoma is detected through comprehensive eye exams that include measuring intraocular pressure, assessing the optic nerve, and evaluating the visual field. Individuals suffering from glaucoma may be suggested the following treatment options:

Medication

Eye drops or oral medications are commonly used to reduce intraocular pressure.

Laser Therapy

Procedures like selective laser trabeculoplasty (SLT) or laser peripheral iridotomy (LPI) can help improve fluid drainage from the eye.

Surgery

In cases where medications or laser therapy are ineffective, surgical interventions like trabeculectomy or drainage implants may be recommended to enhance fluid drainage and reduce intraocular pressure.

Treatment Suitability

Can you have surgery with glaucoma?

Laser Eye Surgery

The eligibility for laser eye surgery, such as LASIK or PRK, depends on various factors and the specific situation of the individual with glaucoma. In general, laser eye surgery is not recommended for individuals with glaucoma because these procedures can potentially affect intraocular pressure, which is a significant concern in managing glaucoma.

ICL or RLE Surgery

An alternative option for individuals with both glaucoma and refractive errors seeking vision correction could be refractive lens exchange (RLE) or implantable contact lenses (ICL). These procedures involve placing a lens either in front of the natural lens (ICL) or replacing the natural lens (RLE), which might be more suitable for some individuals with glaucoma.

Ultimately, the decision to undergo any vision correction procedure when diagnosed with glaucoma requires a comprehensive evaluation by a qualified eye care professional who can assess the risks and benefits based on the individual's specific eye health and the severity of their glaucoma. Always consult with your eye care provider to determine the most appropriate and safe options for vision correction if you have glaucoma.
