Have you had sudden changes to your vision and aren't sure why?

Glaucoma can cause vision loss even before you notice the signs or symptoms.

Our board-certified doctors at Ohio Vision in Sidney, OH, can detect and treat the early signs of glaucoma to prevent further vision loss.

What Is Glaucoma?


Glaucoma is a group of related eye disorders that, if left untreated, can cause irreversible damage to your optic nerve and vision. The condition rarely presents immediate symptoms but can lead to vision loss and eventually blindness if left unmanaged.

The Symptoms Know The Warning Signs to Prevent Vision Loss

Different types of glaucoma produce different symptoms. Open-angle glaucoma, the most common type, typically doesn't show signs or symptoms until there is significant vision loss. Routine eye exams are necessary for preventing the progression of the disorder.

Open-Angle Glaucoma

The slow onset of this type of glaucoma makes the signs and symptoms difficult to notice. If you notice blind spots in your central or peripheral vision, or if you experience tunnel vision, call your doctor immediately to see if this is being caused by glaucoma.

Angle-Closure Glaucoma

The quick onset of this type makes the symptoms immediately apparent to the patient. Symptoms of this include eye pain, blurred vision, seeing halos around lights, nausea, and headache. Call your doctor immediately as this is considered an emergency.

Rave Reviews for Our Doctors

"I have never been treated with such VIP service in my life then at  my recent visit with Ohio Vision.  I contacted my regular eye doc after having repeated issues with the same eye and he referred me over to Doctor Schemmel who proceeded to diagnosis my issue and immediately made a few phone calls to set up an appointment for me the same day up in Sydney to have surgery to correct my issue. Unreal Service!!!   Highly Recommend!!!" Larry Middaugh

How We Diagnose For Glaucoma

When you come in for your exam at our Sidney, Celina, Troy, or Bellefontaine office, our doctors will go over your medical history, family history, and any symptoms you may be experiencing. Then a series of tests could be performed to determine if you have glaucoma.
Routine eye exams are crucial to maintain your optic health.

This is a simple test that measures your eye pressure by using a gentle puff of air.

Visual Field Test

By evaluating your full range of vision, we can detect glaucoma symptoms. The visual field test is done by placing a light in your peripheral vision to test its range.

Dilated Eye Exam

This is a way for us to assess the optic nerve through the use of a slit lamp to ensure there is no damage occurring. 


We examine the corneal thickness through the use of an ultrasound.

Glaucoma Treatment Options Non-Surgical and Minimally Invasive

Your glaucoma treatment will depend on the severity of your symptoms. Our doctors can care for most patients with eye drops and prescriptions, but minimally invasive surgery or lasers are necessary in some cases.

Eye Drops

Prescription eye drops are typically the first choice of treatment for glaucoma patients. The eye drops are either prescribed to increase the drainage of the eye or to reduce the production of fluid within the eye. Both are aimed at reducing eye pressure and preventing further optic nerve damage.

Prescription Medications

Sometimes prescription medications will be given to reduce the production of aqueous humor and significantly reduce eye pressure. Eye drops and medication cannot cure glaucoma or the damage that has already occurred to the optic nerve, but they can stop the progression.

Minimally Invasive Surgery

For more severe cases, our eye doctors may recommend a patient undergo a minimally invasive surgery. Which surgery our doctors recommend will depend on the severity of the patient's condition. Our board-certified doctors use sophisticated technology, such as lasers, to help patients manage their glaucoma. 

Our team is led by elite eye doctors. Each has earned board certification in their respective disciplines, signifying an advanced level of knowledge and skill as ophthalmologists and optometrists.
