Understanding NAION: Sudden Vision Loss from Optic Nerve Ischemia

Non-Arteritic Anterior Ischemic Optic Neuropathy — commonly called NAION — is one of the most disorienting vision emergencies a person can experience. Patients often wake up one morning to find that part of their visual field has simply disappeared, typically as an altitudinal defect that cuts away the upper or lower half of sight in one eye. There is no pain. There is no warning. And in conventional medicine, there is currently no approved treatment.

NAION occurs when blood flow to the anterior portion of the optic nerve is suddenly reduced or interrupted. Without adequate circulation, optic nerve fibers sustain ischemic injury — some cells die, others enter a state of dormancy. The degree of permanent vision loss depends on how many nerve fibers are affected and how quickly the body can respond. Conventional ophthalmology monitors the condition and manages underlying cardiovascular risk factors, but offers no direct intervention to support recovery of visual function.

This is where acupuncture and Chinese medicine offer a meaningful path forward — not as a guarantee of recovery, but as a structured approach to supporting the body’s own regenerative capacity and preserving the vision that remains.

How Chinese Medicine Views Optic Nerve Ischemia

In Chinese medicine, the eyes are understood as an outpost of the internal organ systems — nourished by the Liver blood, anchored by Kidney essence, and lit by Heart fire. When vision fails suddenly, practitioners look first at the circulation of Qi and Blood to the sensory organs. An ischemic event like NAION falls squarely into the pattern of Qi and Blood stasis — an obstruction in the fine channels that carry nourishment to the optic nerve fibers.

Underlying this stasis, there is almost always a root deficiency. The Kidney governs the bones, the brain, and the deeper structural integrity of the nervous system. The Liver governs the tendons, the smooth flow of Qi through the body, and — critically — the eyes themselves. When Kidney essence and Liver blood are insufficient, the fine structures of the optic nerve become vulnerable to ischemic insult. This is why NAION disproportionately affects people in their 50s, 60s, and beyond: years of accumulated deficiency create a terrain in which a temporary dip in perfusion pressure becomes a lasting injury.

Treatment in Chinese medicine therefore works on two levels simultaneously:

Addressing the stasis: Moving Qi and Blood through the channels that supply the optic nerve, reducing the obstructive pattern that follows ischemic injury.
Rebuilding the root: Tonifying Kidney essence and Liver blood to restore the foundational nourishment that the optic nerve depends on for long-term structural integrity.

Micro Acupuncture 48 (MA48) for Optic Nerve Conditions

At Makari Wellness, NAION treatment draws on a specialized microsystem protocol called Micro Acupuncture 48 (MA48) — a 48-point system developed by Andy Rosenfarb, ND, LAc, over two decades of clinical focus on ophthalmic disease. MA48 uses 24 points on the hands and 24 points on the feet, mapped according to the holographic ECIWO principle, which holds that the extremities contain a projected representation of the whole organism.

NAION is treated within the optic nerve protocol family in this system, alongside glaucoma and optic nerve atrophy. The foundational moves center on the Liver, Kidney, and Gallbladder meridian points at the feet — specifically LR-A/B, KI-A, and GB-A/B — which correspond to the deeper nourishment and structural pathways of the visual system. The A-point and B-point pairing is particularly important in post-ischemic cases: A-points address functional and energetic recovery (the dormant nerve fibers that may still respond), while B-points address the chronic, root-deficiency layer underneath.

Because NAION involves both an acute vascular event and an underlying deficiency pattern, treatment sessions typically work both poles — gently activating the circulation to the optic nerve while simultaneously reinforcing the Kidney and Liver root.

What Research and Clinical Experience Suggest

We are honest with our patients about what the evidence currently shows. There are no large randomized controlled trials establishing acupuncture as a standard of care for NAION. What does exist is a growing body of clinical observation and smaller studies suggesting that acupuncture may support circulation to the optic nerve, reduce inflammatory signaling in ischemic tissue, and promote neural recovery in ways that conventional ophthalmology has not yet fully characterized.

From a Chinese medicine perspective, the window immediately following an ischemic event — the first weeks and months — is the most important time to act. Dormant nerve fibers that have not yet fully degenerated may still respond to treatment. Waiting is not necessarily the safer option; in TCM terms, it allows stasis to consolidate and the root deficiency to deepen.

We make no promises about outcomes. Every case of NAION is different, and visual recovery depends on the extent of initial injury, the patient’s underlying constitution, and how early treatment begins. What we offer is a structured, evidence-informed protocol designed to support the conditions in which recovery is most possible.

What to Expect at Makari Wellness

Patients coming to our Oceanside and San Diego locations for NAION support begin with a comprehensive intake that covers the visual event itself, current ophthalmology findings, cardiovascular history, sleep patterns, and constitutional presentation. We review any available imaging and work in coordination with your retinal specialist or neuro-ophthalmologist — Chinese medicine is not a replacement for conventional ophthalmic monitoring, and we take that collaboration seriously.

Treatment Structure

Based on the MA48 clinical model, we organize treatment into three phases aligned with where you are in recovery:

Recharge and Recover (Weeks 1–4, intensive): Frequent sessions aimed at arousing dormant nerve cells, moving stasis, and establishing the foundation of treatment. This phase is most effective when begun as early as possible after the ischemic event.
Repair and Regenerate (Months 1–12, repeat rounds): Continued treatment to support healthy cell repair and consolidate any functional gains. This is where the deeper root work — tonifying Kidney and Liver — becomes primary.
Maintenance and Preservation (Long-term): For many patients with optic nerve conditions, the most meaningful goal is stabilization — preventing further loss and maintaining the vision that remains. Regular maintenance sessions support this over the long term.

During a Session

MA48 treatments use very fine needles placed at specific points on the hands and feet. Sessions are gentle and generally well-tolerated. Most patients feel a quiet, settling quality to the treatment — some report mild warmth or tingling in the eyes or head during the session. Acupuncture at the extremities is safe and does not involve needling near the eye itself.

Depending on your individual presentation, your practitioner may also recommend herbal formulas or targeted nutritional supplements to support retinal and optic nerve health between sessions. These recommendations are individualized — not a fixed protocol applied to everyone.

Tracking Progress

We encourage patients to continue their ophthalmology follow-ups throughout treatment and to share any visual field testing or OCT findings with us. Objective measurement helps both you and your practitioner understand how treatment is working and adjust the approach accordingly. In some cases, functional improvements are perceptible before they show up on formal testing; in others, the primary benefit is stabilization rather than measurable recovery.

Is This the Right Fit for You?

NAION is a serious condition, and navigating it is rarely simple. If you are in the acute phase — days or weeks after the event — reaching out quickly gives the best opportunity for treatment to be meaningful. If you are further out from the initial episode and wondering whether it is too late, the answer in most cases is no: supporting circulation, rebuilding root deficiency, and preventing progression remain worthwhile goals at any stage.

If you have been told by conventional ophthalmology that there is nothing more to be done, we understand how that feels. Our role is not to contradict that assessment or to promise what we cannot deliver — it is to offer a thoughtful, patient-centered approach that may support your body’s capacity to recover and preserve what remains.

If you or someone you love is dealing with NAION and would like to explore whether acupuncture may be a supportive part of your care, we invite you to Schedule Your Initial Visit with our team at Makari Wellness in Oceanside or San Diego — we are here to listen, answer your questions honestly, and build a treatment plan grounded in both clinical expertise and genuine care for your vision.
