What is Glaucoma?
- Definition: A condition characterized by damage to the optic nerve, often associated with elevated intraocular pressure (IOP), leading to vision loss.
- Types:
- Open-Angle Glaucoma: The most common form, where the eye’s drainage canals become clogged over time.
- Angle-Closure Glaucoma: Occurs when the drainage angle is blocked suddenly, leading to rapid increase in eye pressure.
- Normal-Tension Glaucoma: Optic nerve damage occurs despite normal eye pressure levels.
- Secondary Glaucoma: Resulting from other medical conditions or eye injuries.
Symptoms to Watch For
- Gradual Vision Loss: Often peripheral vision is affected first, leading to tunnel vision.
- Eye Pain: Particularly in acute angle-closure glaucoma, which may be accompanied by nausea and vomiting.
- Headaches: Frequent or severe headaches, especially around the eyes.
- Halos Around Lights: Seeing rainbow-colored circles around lights, a common symptom of acute glaucoma.
- Blurred Vision: Difficulty seeing clearly, particularly in low light.
Risk Factors
- Family History: A family history of glaucoma increases the risk of developing the condition.
- Age: Risk increases with age, particularly after age 40.
- Ethnicity: Higher prevalence in African-Americans and people of Asian descent.
- High Intraocular Pressure: Elevated pressure within the eye is a major risk factor.
- Medical Conditions: Conditions like diabetes, hypertension, and hypothyroidism can increase risk.
- Use of Corticosteroids: Long-term use of steroid medications can elevate eye pressure.
Our Diagnostic Approach
- Comprehensive Eye Examination: Includes testing for intraocular pressure and assessing overall eye health.
- Optical Coherence Tomography (OCT): Provides detailed images of the optic nerve and retinal nerve fiber layer to detect damage.
- Visual Field Testing: Measures the full range of vision to identify any loss of peripheral vision.
- Gonioscopy: Examines the drainage angle of the eye to determine if it is open or closed.
- Pachymetry: Measures the thickness of the cornea, as corneal thickness can affect glaucoma risk.
Effective Treatments We Offer
- Medications: Prescription eye drops or oral medications to lower intraocular pressure and slow disease progression.
- Laser Therapy: Laser treatments, such as laser trabeculoplasty, to improve fluid drainage and lower eye pressure.
- Surgical Procedures: Advanced surgical options, including trabeculectomy or drainage implants, to create a new drainage pathway for aqueous humor.
- Regular Monitoring: Ongoing assessments to track disease progression and adjust treatment as needed.
Prevention and Management Tips
- Regular Eye Exams: Essential for early detection and management of glaucoma, especially if you have risk factors.
- Medication Adherence: Consistently using prescribed medications to maintain controlled intraocular pressure.
- Lifestyle Adjustments: Maintaining a healthy diet, regular exercise, and avoiding excessive caffeine can support overall eye health.
- Protective Eyewear: Wear protective eyewear during activities that pose a risk of eye injury to prevent secondary glaucoma.
