Unfortunately, there’s no confirmed effective treatment for nonarteritic ION. Corticosteroid medications are usually not recommended when you don’t have an underlying arteritis-type condition.
Experts aren’t sure exactly why NAION happens, but they think it’s usually due to several factors that add up and disrupt circulation in your optic nerve. The factors usually affect how your circulatory system regulates blood flow through your optic nerve. As long as that self-regulation works like it should, you won’t have NAION. But certain events or issues can disrupt that self-regulation. They include:
This presentation will discuss efforts at Optimax to address this need through advancement of robotic smoothing platforms and processes.
Optical designers assume a mathematically derived statistical distribution of the relevant design parameters. However, there may be significant differences between the assumed distributions and the likely outcomes from manufacturing.

Ischemic optic neuropathy (ION) is when you have sudden vision loss or changes because your optic nerves aren’t getting enough blood flow. It’s rare and is most likely to happen in people over 50. Permanent vision loss is possible, so it’s important to get care fast and limit the damage this condition can cause.
The cost of lenses is strongly dependent on the difference between the specified tolerances and the limits of the optics manufacturer, the coater, and the metrologist.
The main symptom of ION is vision loss. The way it happens can vary depending on the type of ION. Other symptoms also vary depending on the ION type.

Another reason they’re similar is because people with ION can sometimes have early symptoms that go away. When that happens, it means you have a higher risk of developing optic nerve ischemia and vision loss in the following days. So, you shouldn’t ignore sudden vision loss, and having it means you should get emergency medical care right away.

Some tests specifically diagnose or rule out arteritis-type conditions (which need specific treatments as soon as possible). These tests can include:
If you have a condition that can cause sudden vision loss or ION, it’s a good idea to talk to your eye care specialist. They can tell you what to watch for and what to do if you notice vision changes. Acting quickly could make all the difference and help protect you from more serious vision disruptions and difficulties.
Optical prisms, for example, which are ground and polished to create geometrically complex optical components with extremely tight tolerances, represent a costly bottleneck for many optics fabricators. Their variability makes it difficult to process prisms at large scales or via automated processes. At Optimax, we can confidently commit to delivery schedules of a single week for optical dispersion prisms, blocks, doves, right angles, mirror substrates, and more.
Vascular risk factors increase the risk of ION. These include high blood pressure, diabetes, high cholesterol, smoking, sleep apnea and other factors listed above. And inflammatory diseases such as giant cell arteritis increase the risk of developing ION. ION happens more often among certain groups. For example, individuals over age 50, people assigned male at birth (AMAB) and white people are more likely to develop ION.
An eye care specialist can diagnose ION using a combination of methods. The diagnosis process usually starts with asking you questions about your symptoms, recent life events, medical history and more. Your answers can help them narrow down the list of causes and rule out conditions similar to ION. They’ll also do an eye exam, with special emphasis on parts where they look at the optic disk at the back of your eye.
This paper will define surface irregularity for spherical surfaces, offer information on measurement methods for testing surface irregularities, and some specification guidelines.
The treatments for ION vary depending on the cause. Sometimes, a provider can treat ION directly. Other times, the only approach is to manage the vascular risk factors and focus on treating the symptoms.
Arteritic conditions involve arterial inflammation (arteritis). These conditions usually happen with types of vasculitis (blood vessel inflammation). Nonarteritic means there’s no arterial inflammation and it usually happens because of limited blood flow to the optic nerve.

ION is also something that medical professionals will take steps to prevent if you need to undergo surgery. If you have a history of ION or know you have a condition that could cause it (like GCA or vasculitis), tell your surgeon and/or anesthesiologist before your procedure so they can plan and adjust accordingly.

Your eye care specialist will schedule regular follow-up visits to monitor you for any changes in your vision or your eyes themselves. You should see them as recommended and contact them as soon as possible if you notice any changes in your vision. They can also tell you other specific changes that mean you need to call them or seek urgent medical attention.
ION isn’t preventable, but you can lower your risk of developing it. The main way to do that is to prevent or manage conditions that can cause or contribute to ION. Your provider may recommend adjusting your blood pressure medication to avoid low blood pressure while sleeping, start you on medications to lower your cholesterol, adjust your diabetes medications, recommend quitting tobacco (including vaping) and other preventive measures to decrease your chances of developing ION.

ION may be reversible in some cases, but it usually causes at least some permanent vision loss. But people with vision loss also often learn to adapt to this condition and shift what areas of their vision they use for specific tasks like reading. When that happens, their vision may seem to improve, but it’s really that they’re better at working around their vision loss.
At Optimax, we specialize in manufacturing optical prisms up to 300 mm in diameter, and with our state-of-the-art grinding and smoothing technologies, can deliver prisms in a variety of complex geometries to tightly-defined surface flatness.
Most people first notice they have vision loss when waking up (either from longer sleep periods or brief naps). Less commonly, vision loss may happen gradually over about two weeks.
NAION, the most common form of ION, usually affects one eye at a time. About 15% of people who have NAION in one eye eventually develop it in their other eye, too.
Optimax has developed a fabrication process that not only reduces cost but also aids in producing spherical sapphire components to better figure quality.
Anterior and posterior arteritic ION need quick treatment with anti-inflammatory corticosteroid medications like prednisone or the immune-suppressing drug tocilizumab (Actemra®). Corticosteroids usually come in oral pill form but sometimes come in intravenous (IV) form (through a vein in your arm). The corticosteroid doses start high and gradually decrease over days or weeks. Some people may need to take low doses of these medications for an extended period to prevent ION from causing permanent vision problems.
AAION usually causes sudden vision loss. That means it can cause blurring, darkening or dimming, worsened vision or complete loss of vision. AAION generally involves symptoms from arteritis-related conditions that cause AAION. These symptoms can include:

ION usually causes sudden vision loss. “Sudden” can mean it happens over minutes or hours, but sometimes. it can take days. The more common forms of ION cause blurring or weakened vision, while some forms cause total vision loss. Sometimes, people have brief episodes of blurred vision before they develop vision loss from ION.

If you previously had nonarteritic ION in one eye, you’ll need to be vigilant for vision changes or loss in your other eye. That’s because having it in one eye makes you more likely to develop it in your other eye later on.
Arteritic and nonarteritic PION both cause sudden, painless vision loss. But PION is usually a progressive condition early on, meaning the symptoms get worse in the initial phase.
Optical prisms differ from traditional lenses in that they have neither a spherical surface nor an axis of symmetry. Instead, they comprise two or more nominally plano surfaces divided by a wedge angle. This alters the language used to define and specify optical prisms, and it typically increases production time due to increased part complexity and a greater number of sides requiring precision finishing.
The significance of these geometries is that they will reflect or refract light, resulting in several distinct functions: dispersion, deflection, reflection, and rotation. These go on to serve critical applications in dual channel instruments, anamorphic systems, imaging systems, and any other application where beam steering and/or image manipulation is needed.

The sudden vision loss that happens with ischemic optic neuropathy means your optic nerves aren’t getting enough blood flow. Over time, that can cause permanent damage and vision loss, so sudden vision loss is never something to ignore or wait on and see if it gets better.
Optical prisms vary dramatically by size, shape, and number of surfaces. Defining the part geometry requires a careful selection of directly measurable physical parameters, including linear dimensions of the plano surfaces to theoretical sharps (the intersection that would exist between the two if the corner was not beveled). Manufacturers must also specify part thickness, which is the depth of separation between the two plano surfaces at a single point on the optic. At Optimax, we choose to specify the thickest edge as it offers ease-of-measurement access, but we can specify our optical prisms by the centerline thickness, or the thinnest edge if necessary.
Any sudden vision loss is an emergency symptom that needs immediate medical care. That’s because it can sometimes be a symptom of life-threatening conditions like a stroke or eye emergencies like a detached retina (which is reversible if treated quickly).
Ischemic optic neuropathy (ION) refers to several conditions that all cause vision loss because of a lack of blood flow to part of your optic nerve. Without blood flow, the affected areas stop working correctly and start to die. If the disruption in blood flow is severe or lasts too long, it can damage the optic nerve permanently.
If you have ION-related vision loss, your healthcare provider may recommend assistive devices like magnifiers or using magnification settings or voice commands/feedback on your devices. These can help you compensate or work around vision issues.
If you had arteritic ION, your eye care specialist will refer you to a specialist like a rheumatologist. A rheumatologist can help monitor and treat the underlying immune or inflammatory conditions causing your arteritis. It’s important to follow your eye care specialist and other providers’ guidance on managing your condition. That can help you prevent future flare-ups and additional vision loss or issues.
For now, the main approach to treating nonarteritic ION is to manage the symptoms and treat or minimize any underlying causes and contributing factors. That’s important because nonarteritic ION usually affects one eye at a time, so this approach can lower your risk of having ION-related vision loss in both eyes.

It takes a trained medical professional and specific tests to tell when sudden vision loss is truly an emergency issue, and minutes can make all the difference. That’s why you shouldn’t ignore sudden vision loss if you’ve never had it before. And if you have a condition that can cause or previously caused sudden vision loss, talk to your healthcare provider. They can explain when this symptom needs emergency care and when it’s something you should expect with your condition.
