What You Need to Know About Glaucoma Awareness Month

January is National Glaucoma Awareness Month, a time dedicated to educating people about glaucoma, its risk factors, and the importance of early detection. As one of the leading causes of irreversible vision loss in the United States, glaucoma affects millions worldwide – yet many don’t realize they have it until significant damage has already occurred.

Why Awareness Matters

Glaucoma often has no noticeable symptoms in the early stages, making routine eye exams a critical part of early detection. Raising awareness for this eye condition can help people prevent themselves from permanent vision loss by promoting timely treatment and proactive eye care.

A Deep Dive into Glaucoma

Definition: Glaucoma is a group of progressive eye diseases that damage the optic nerve, leading to vision loss and, if left untreated, blindness. While most cases are associated with high intraocular pressure (IOP), some types can develop even when eye pressure is within a normal range.

How Glaucoma Affects Vision

The optic nerve is responsible for transmitting visual information from the eye to the brain. When glaucoma damages this nerve, it disrupts vision – typically starting with small blind spots in peripheral vision. Over time, optic nerve damage can progress, leading to significant vision impairment or complete blindness.

Types of Glaucoma

Open-Angle Glaucoma

  • The most common type – develops when the eye’s drainage system becomes blocked.
  • Progresses slowly and often goes unnoticed until vision loss occurs.

Angle-Closure Glaucoma

  • A sudden and severe blockage in the eye’s drainage canals causes a rapid rise in eye pressure.
  • Symptoms are severe eye pain, blurred vision, nausea, and headaches.

Secondary Glaucoma

  • Caused by underlying conditions like diabetic retinopathy, cataracts, or eye trauma.
  • Treating the underlying cause can help manage this type of glaucoma.

Congenital Glaucoma

  • Rare and present at birth – occurs due to abnormal eye development in newborns.
  • Early signs include excessive tearing, light sensitivity, and an enlarged eye.

Who is Most at Risk for Glaucoma?

Certain people have a higher likelihood of developing glaucoma due to genetic, medical, and lifestyle factors. Those at greater risk include:

  • African Americans and Hispanics, especially at a younger age
  • Individuals over 40 years old
  • People with long-term steroid use
  • People with a family history of glaucoma
  • Individuals with high intraocular pressure (IOP)
  • Those with chronic conditions – diabetes, heart disease, or extreme nearsightedness
  • People with past eye injuries, thin corneas, or drainage problems

Early Symptoms and Warning Signs

Many people are unaware of glaucoma until significant vision loss has occurred. Some warning signs that may indicate glaucoma include:

  • Blurred vision
  • Frequent headaches
  • Eye strain
  • Halos around lights
  • Difficulty adjusting to low light
  • Patchy blind spots in side vision

Importance of Regular Eye Exams

A comprehensive eye exam is the most reliable way to detect glaucoma early. Since these symptoms often go unnoticed until irreversible damage has occurred, routine screenings are crucial – especially for those at higher risk.

The National Eye Institute recommends annual glaucoma screenings for individuals with risk factors to ensure early diagnosis and treatment.

Glaucoma Prevention and Treatment Options

While glaucoma cannot be cured, early diagnosis and proactive care can help prevent significant vision loss. Steps to reduce risk and slow progression include:

  • Regular comprehensive eye exams – the best way to catch glaucoma early and prevent permanent damage. Get regular eye exams:
    • Before age 40 – every 2 or 3 years
    • From age 40 to 54 – every 1 to 3 years
    • From age 55 to 64 – every 1 to 2 years
    • After age 65 – every 6 to 12 months
  • Maintaining a healthy lifestyle – regular exercise, a balanced diet, and hydration can help lower intraocular pressure.
  • Managing underlying health conditions – controlling blood pressure and diabetes supports overall eye health.

Glaucoma Treatment Options

Although glaucoma damage is irreversible, appropriate treatment can slow or prevent further vision loss. Treatment plans are tailored to each patient’s needs and may include:

Prescription Medications

  • Prescription eye drops that help maintain eye pressure at a healthy level. They measure changes in the peripheral visual field, helping to improve fluid drainage or decrease fluid production.

Laser Treatments for Glaucoma

  • Selective Laser Trabeculoplasty uses short pulses to target specific cells in the eye’s drainage system and stimulate improved function. This procedure can slow or stop the risk of disease progression.

Surgical Procedures

  • Minimally Invasive Glaucoma Surgery (MIGS) – A less invasive option that improves drainage. Widely accepted as one of the most successful techniques for mild-to-moderate glaucoma.
  • Trabeculectomy – A traditional surgery that creates a new drainage pathway to reduce pressure. It’s performed when eye drops or laser surgery aren’t effective.

Lifestyle Adjustments

  • Managing blood pressure and diabetes, maintaining a nutrient-rich diet, and avoiding habits that increase eye pressure (such as smoking) can support long-term eye health.

Can LASIK Fix Astigmatism? Everything You Need to Know

Can LASIK fix astigmatism? The answer is yes. LASIK is a popular and effective refractive surgery that corrects common vision problems like nearsightedness, farsightedness, and astigmatism.

Understanding the Basics of LASIK

LASIK (Laser-Assisted in Situ Keratomileusis) is a widely performed refractive surgery that improves vision and eye health. Developed in the 1990s, LASIK has advanced significantly, offering patients a safe and effective way to reduce or eliminate their dependence on corrective lenses like glasses and contacts.

explaining how LASIK works

How Does LASIK Work?

The LASIK surgical procedure is quick and minimally invasive, typically taking less than 15 minutes for each eye:

  1. Creating the Corneal Flap: Anesthetic eye drops are applied to numb the eye. A femtosecond laser is then used to create a thin flap with precise dimensions.
  2. Reshaping the Cornea: The surgeon lifts the flap to access the underlying corneal tissue and uses an excimer laser to reshape it – correcting refractive errors.
  3. Repositioning the Flap: After reshaping, the flap is carefully repositioned, adhering naturally without the need for stitches.

Vision Problems Addressed by LASIK

LASIK is designed to treat the following eye conditions:

By addressing these refractive errors, LASIK provides long-term vision correction, helping patients achieve clearer sight with minimal downtime.

Astigmatism Explained

Astigmatism is a common refractive error caused by an irregular shape of the cornea or lens. Instead of being perfectly round like a basketball, an eye with astigmatism has an uneven shape, more like a football, that causes blurred vision and distortion.

Types of Astigmatism

There are two main types of astigmatism, each affecting vision differently:

  • Regular Astigmatism: The cornea curves more in one direction than the other, creating a consistent distortion that can typically be corrected with glasses, contact lenses, or LASIK surgery.
  • Irregular Astigmatism: The corneal curvature is uneven or asymmetrical, often caused by injury, scarring, or conditions like keratoconus. This type may require specialized contact lenses or alternative treatments.

Ranging from mild to severe, astigmatism is measured in diopters:

  • Slight: up to .75 diopters
  • Mild: .75-2 diopters
  • Moderate: 2-4 diopters
  • Severe: 4 more or diopters

Traditional Vision Correction Procedures

Astigmatism is commonly corrected through:

  • Eyeglasses: A simple and effective solution that compensates for corneal irregularities.
  • Contact Lenses: Toric lenses are specially designed to correct astigmatism by aligning with the cornea’s unique shape.
  • Refractive Surgery: A LASIK procedure reshapes the cornea to create a more uniform curve, improving light focus and reducing or eliminating the astigmatism.

By understanding astigmatism and its correction options, patients can make informed decisions about the best treatment to achieve clearer, sharper vision.

LASIK’s Role in Correcting Astigmatism

During LASIK laser eye surgery, a highly precise laser removes microscopic amounts of corneal tissue. This process enhances the way light is refracted onto the retina, reducing blurry vision. LASIK has proven to be an effective, long-term solution for astigmatism, providing many patients with sharper sight without the need for glasses or contacts.

The Technology Behind LASIK for Astigmatism Correction

LASIK relies on advanced technology to ensure precision and safety when treating astigmatism.

  • Femtosecond Laser: This ultra-fast laser creates a thin, customized corneal flap with extreme accuracy. The flap gives the eye surgeon access to the underlying corneal tissue while maintaining the integrity of the eye’s surface – which helps to minimize post-surgical complications and ensure a smooth recovery.
  • Excimer Laser: This specialized laser reshapes the cornea by removing microscopic layers of tissue. These lasers are computer-controlled and use a light beam to minimize risks of thermal damage to the tissue.
  • Corneal Topography Mapping: Before LASIK, a detailed 3D image of the cornea is generated using corneal topography. These tools measure even the smallest imperfections in the cornea so the surgeon can precisely correct the astigmatism.

These technological advancements allow for highly individualized treatment, ensuring that each patient receives optimal results tailored to their unique corneal structure.

Comparing LASIK to Other Refractive Surgeries

For patients with astigmatism, LASIK is often the preferred choice, but other procedures may be considered based on individual eye health:

  • PRK (Photorefractive Keratectomy): Similar to LASIK but without a corneal flap; best for those with thinner corneas because it preserves more corneal tissue. However, PRK has a longer recovery period and can cause temporary discomfort.
  • ICL (Implantable Contact Lens): An alternative for patients who are not LASIK candidates and don’t want to permanently alter their cornea. Involves the insertion of an implantable lens inside the eye to correct vision. 

Who is a Good Candidate for LASIK?

For patients with astigmatism, eligibility for LASIK depends on several factors, including:

    1. Stable vision prescription for at least a year
  • At least 21 years old
  1. Sufficient corneal thickness to allow for safe reshaping
  2. Overall eye health, free from conditions like keratoconus or severe dry eye

With its precision and long-lasting results, LASIK remains one of the most effective options for astigmatism correction.
