Glaucoma Diagnosis and Treatment at OC Eye Institute in Laguna Hills and Santa Ana, CA
Glaucoma is one of the leading causes of irreversible blindness worldwide — and what makes it especially dangerous is that it often causes no noticeable symptoms until significant vision has already been lost. At OC Eye Institute in Laguna Hills and Santa Ana, CA, Dr. George Salib uses state-of-the-art diagnostic technology to detect glaucoma early and offers a full range of treatment options, including prescription eye drops, advanced laser therapy, and surgery, to protect your vision for life.

Understanding Glaucoma: The Silent Thief of Sight
Glaucoma is a group of eye conditions that cause progressive damage to the optic nerve — the critical structure that transmits visual information from the eye to the brain. In most cases, this damage is caused or worsened by elevated intraocular pressure (IOP), the fluid pressure inside the eye. When the eye’s natural drainage system becomes inefficient, fluid builds up and IOP rises. Over time, this elevated pressure compresses and damages the delicate fibers of the optic nerve, leading to irreversible vision loss.
What makes glaucoma particularly concerning is how it progresses. Unlike conditions such as cataracts or macular degeneration, which typically affect central vision first, glaucoma initially attacks peripheral (side) vision. Because humans are highly adaptable and the brain compensates for gradual vision loss at the edges of the visual field, most patients with early to moderate glaucoma have no idea anything is wrong. By the time central vision is affected — or vision changes become noticeable in daily life — the disease has usually reached an advanced stage. This is why regular comprehensive eye examinations are essential, especially for individuals at higher risk.
Risk factors for glaucoma include age (the risk increases significantly after 60), a family history of glaucoma, elevated intraocular pressure, African or Hispanic ancestry, thin corneas, and certain medical conditions including diabetes and high blood pressure. Some forms of glaucoma can occur even when IOP is within the normal range — a condition called normal-tension glaucoma — which is why pressure measurements alone are not sufficient for a complete glaucoma evaluation.
Comprehensive Glaucoma Testing at OC Eye Institute
At OC Eye Institute in Laguna Hills and Santa Ana, CA, our glaucoma evaluation is thorough, precise, and completely comfortable. We utilize a full suite of diagnostic equipment to assess every relevant aspect of your eye health. Our testing includes two types of visual field testing machines to map peripheral vision in detail, an optic nerve analyzer to image and measure the health of the optic nerve and its surrounding tissue, and corneal pachymetry — a test that measures the thickness of your cornea, which affects the accuracy of IOP readings and is itself a risk factor for glaucoma progression.
Importantly, we measure your eye pressure without the air puff method that many patients find unpleasant. Instead, we use more accurate and comfortable contact tonometry techniques. After all diagnostic tests are completed, Dr. Salib performs a comprehensive dilated eye examination, correlates all findings, and presents you with a clear, complete picture of your glaucoma risk or status along with a thoughtful, personalized treatment recommendation.
Glaucoma Treatment Options
The primary goal of glaucoma treatment is to lower intraocular pressure to a level that stops or slows the progression of optic nerve damage. While lost vision cannot be restored, treatment can effectively preserve the vision you have. At OC Eye Institute, we offer a range of treatment options tailored to each patient’s individual needs and disease stage.
Prescription eye drops are the most commonly used first-line treatment for glaucoma. These drops work by either reducing the amount of fluid the eye produces or improving the drainage of fluid from the eye, effectively lowering IOP. Consistent daily use is essential for eye drops to be effective. For patients who prefer a less medication-dependent approach, or for whom drops are not achieving adequate pressure control, laser therapy is an excellent option. Our laser eye treatments page describes Selective Laser Trabeculoplasty (SLT) in detail — a modern, minimally invasive laser procedure performed right in our clinic that improves fluid drainage and lowers eye pressure effectively. In cases where eye drops and laser treatment are not sufficient, surgical procedures to create new drainage pathways may be necessary.
Do not wait for symptoms to appear — by then, significant vision may already be lost. Contact OC Eye Institute in Laguna Hills and Santa Ana, CA at (949) 770-1322 - Laguna Hills Office or (949) 770-1322 - Santa Ana Office to schedule your glaucoma evaluation. Early detection and consistent treatment are the most powerful tools available for preserving your vision.
Frequently Asked Questions About Glaucoma
What are the early signs of glaucoma?
In the most common form — open-angle glaucoma — there are typically no early warning signs or symptoms. Vision loss begins at the periphery and progresses so gradually that most people do not notice it until the disease is advanced. This is why glaucoma is often called “the silent thief of sight” and why routine comprehensive eye exams are so important. If you are over 40 or have risk factors for glaucoma, schedule a comprehensive evaluation at OC Eye Institute in Laguna Hills and Santa Ana, CA by calling (949) 770-1322 - Laguna Hills Office or (949) 770-1322 - Santa Ana Office .
Who is most at risk for developing glaucoma?
The primary risk factors for glaucoma include age over 60, a family history of glaucoma, elevated intraocular pressure, African or Hispanic ancestry, thin corneas, diabetes, high blood pressure, and a history of eye trauma. People with certain refractive errors such as high myopia (nearsightedness) may also be at increased risk. If you have one or more of these risk factors, it is especially important to schedule regular glaucoma screenings at OC Eye Institute in Laguna Hills and Santa Ana, CA.
Can glaucoma be cured?
There is currently no cure for glaucoma, and vision that has been lost to the disease cannot be restored. However, with early detection and appropriate treatment, glaucoma can be effectively managed to slow or halt its progression and preserve the vision you have. This is why routine eye exams and proactive monitoring are so important — catching glaucoma early gives you the best possible chance of protecting your long-term vision quality. Our team at OC Eye Institute will work with you to develop a management plan that keeps your eye pressure under control.
How is glaucoma treated at OC Eye Institute?
At OC Eye Institute in Laguna Hills and Santa Ana, CA, glaucoma treatment options include prescription eye drops to lower intraocular pressure, Selective Laser Trabeculoplasty (SLT) — a minimally invasive in-office laser that improves drainage and reduces IOP — and surgical procedures for more advanced cases. The right treatment depends on the type and stage of glaucoma, the level of IOP, and the patient’s overall eye health. Dr. Salib will present all available options and help you make an informed decision at your consultation.
Is the glaucoma testing process painful?
No. All of the glaucoma testing performed at OC Eye Institute is non-invasive and comfortable. We measure eye pressure without the air puff method that many patients dislike, using more accurate and comfortable alternatives instead. Visual field testing, optic nerve imaging, and corneal thickness measurement are all quick and painless. Dr. Salib then reviews all findings with you in a thorough, unhurried consultation. Call (949) 770-1322 - Laguna Hills Office or (949) 770-1322 - Santa Ana Office to schedule your glaucoma evaluation today.
What is the difference between open-angle and angle-closure glaucoma?
Open-angle glaucoma is the most common form and occurs when the eye’s drainage angle remains open but the trabecular meshwork — the filtering tissue within the angle — becomes less efficient over time, causing a gradual rise in IOP. It develops slowly and silently. Angle-closure glaucoma occurs when the drainage angle itself becomes physically blocked, often suddenly, causing a rapid and dangerous spike in IOP. Acute angle-closure glaucoma is a medical emergency. Our laser eye treatments include Laser Peripheral Iridotomy (LPI), which can prevent angle-closure attacks in at-risk patients.
