Auditory Neuropathy Optic Atrophy Syndrome (ANOA)

Auditory neuropathy–optic atrophy syndrome (ANOA) is a rare neurological condition in which the hearing nerve pathway does not transmit sound signals properly (auditory neuropathy) and the optic nerves slowly waste away (optic atrophy), causing problems with both hearing and vision. Many people first notice difficulty understanding speech—especially in noise—despite sounds seeming loud enough, and later develop blurred vision, reduced color vision, and pale optic discs on eye exam. In most families described so far, ANOA is genetic, often related to mitochondrial energy problems inside nerve cells. Symptoms typically begin in childhood or the teenage years and may progress slowly. ANOA has been reported as an autosomal-recessive disorder in several families, but related gene changes can also appear in autosomal-dominant or X-linked conditions that produce a very similar combination of findings. NCBI+1

Auditory Neuropathy–Optic Atrophy Syndrome is a rare neuro-sensory disorder where the hearing system and the visual system are both affected. In the ear, sound can enter normally, but the electrical signals do not travel properly along the auditory nerve or do not fire in a synchronized way—this is called auditory neuropathy. In the eye, the cable that carries visual signals from the retina to the brain—the optic nerve—becomes thin and weak over time, which is called optic atrophy. People may notice trouble hearing speech clearly (especially in noisy places), and slowly worsening vision with pale optic nerves on eye exam. This pattern can occur in OPA1-related dominant optic atrophy (“DOA+”), AIFM1-related X-linked disease, or TIMM8A-related Mohr-Tranebjaerg (DDON) syndrome, among others. There is currently no cure, but early diagnosis, hearing rehabilitation (often cochlear implants), low-vision care, and supportive therapies can greatly improve daily life. NCBI+3PMC+3PMC+3

• Auditory neuropathy-optic atrophy syndrome (ANOAS)

• Optic atrophy with auditory neuropathy

• Phenotypic labels sometimes used in reports of related genetic disorders:

  • OPA1-related disease with auditory neuropathy (DOA+)

  • TMEM126A-associated optic atrophy with auditory neuropathy

Types

Because ANOA is defined by what the nerves do (hearing pathway + optic nerves) rather than a single gene, clinicians often group cases by cause:

1. Autosomal-recessive ANOA (classic): Reported in families with TMEM126A variants. Onset in childhood/teens with hearing difficulty and progressive optic atrophy. PubMed+1

2. Autosomal-dominant optic atrophy plus (DOA+) with auditory neuropathy: Due to OPA1 variants; optic atrophy is typical, and some individuals develop auditory neuropathy and other neurologic features. PMC+1

3. X-linked ANOA-like presentations: Variants in AIFM1 can cause auditory neuropathy, sometimes with optic atrophy and peripheral neuropathy/ataxia. PMC+1

4. Other mitochondrial-related AN with optic neuropathy: Emerging reports implicate mitochondrial genes (e.g., FDXR, TWNK) in non-isolated auditory neuropathy with visual pathway involvement. BioMed Central

---

Causes

Most causes are genetic and disturb how mitochondria make energy in nerve cells. Below are well-documented and biologically plausible causes that produce the same clinical combination or a very close overlap.

1. TMEM126A variants (autosomal-recessive): Disrupt a protein involved in assembling mitochondrial complex I; leads to poor energy supply in optic and auditory pathways. PMC+1

2. OPA1 variants (autosomal-dominant): Damage a mitochondrial fusion protein; beyond optic atrophy, some patients develop auditory neuropathy (a DOA+ phenotype). PMC+1

3. AIFM1 variants (X-linked): Alter an oxidative phosphorylation (OXPHOS) factor; reported with auditory neuropathy plus optic atrophy or retinopathy. PMC+1

4. FDXR variants: Affect ferredoxin reductase, disturbing mitochondrial iron–sulfur cluster function; linked to non-isolated auditory neuropathy with visual system involvement. BioMed Central

5. TWNK variants: Impair mtDNA helicase; may cause multi-system mitochondrial dysfunction with auditory neuropathy and optic nerve involvement. BioMed Central

6. OPA1 frameshift/delTTAG model evidence: Animal data show progressive auditory neuropathy from OPA1 dysfunction, supporting a causal pathway for human disease. SpringerLink

7. Broader OPA1 genotype–phenotype mechanisms: Meta-analyses link different OPA1 variants to extra-ocular features, including hearing impairment due to neural pathway damage. ScienceDirect

8. Mitochondrial respiratory chain assembly defects (general): When proteins that assemble complex I/III/IV are disrupted (e.g., TMEM126A), energy failure preferentially injures long axons like the optic nerve and auditory nerve fibers. PMC

9. Mitochondrial dynamics imbalance: Faulty fusion/fission (e.g., OPA1) leaves neurons vulnerable to stress, producing the ANOA phenotype. PMC

10. X-linked mitochondrial apoptosis signaling defects: AIFM1 changes can disturb redox and apoptotic pathways in auditory/optic neurons. ScienceDirect

11. Secondary mtDNA depletion/instability: Genes that maintain mtDNA (e.g., TWNK) can secondarily harm optic/auditory neurons. BioMed Central

12. Synaptopathy in the inner ear with preserved outer hair cells: The cochlea’s inner hair cell–nerve synapse fails even though otoacoustic emissions persist—classic for auditory neuropathy and common in mitochondrial disorders. PMC

13. Neurodegeneration in the auditory brainstem pathway: Energy failure can also affect post-synaptic auditory nuclei, explaining absent/abnormal ABRs. PMC

14. Axonopathy of retinal ganglion cells (optic nerve): Mitochondrial dysfunction injures retinal ganglion cell axons, producing optic disc pallor and central/cecocentral scotomas. PMC

15. Calcium/ROS imbalance in neurons: Mitochondrial defects raise oxidative stress and disrupt calcium buffering, which is toxic to long myelinated fibers. (Inference from mitochondrial disease mechanisms discussed in OPA1/AIFM1 literature.) PMC+1

16. Protein assembly defects at the inner mitochondrial membrane: Structural studies show TMEM126A participates directly in complex I assembly, linking gene to phenotype. PMC

17. Potential involvement of additional mitochondrial genes: New sequencing studies keep expanding the list; the unifying theme is impaired oxidative metabolism in auditory/optic pathways. BioMed Central

18. Rare X-linked mimics (e.g., Mohr-Tranebjaerg/TIMM8A): Classically causes hearing loss and optic atrophy; although not always “auditory neuropathy,” it is a close phenocopy to consider in the differential. Frontiers

19. Wolfram syndrome (WFS1) spectrum in the differential: Optic atrophy + hearing loss can occur; most cases are not auditory neuropathy, but clinicians consider it during work-up. ScienceDirect

20. Undiagnosed mitochondrial cytopathies: Some families show the same combined phenotype without a defined gene; exome/genome sequencing can later uncover the cause. (General mitochondrial ANSD framework.) PMC

Diagnostic tests

A) Physical examination (general & eye/ear focused)

1. Focused neurologic and cranial nerve exam: Checks eye movements, facial strength, coordination, and sensation; looks for ataxia or peripheral neuropathy that can accompany some genetic types. PMC

2. Otolaryngologic exam: Inspects ear canals and eardrums (usually normal in AN) and screens for middle-ear disease so hearing test results are interpreted correctly. PMC

3. Neuro-ophthalmic exam: Measures visual acuity, color vision, pupils, and inspects the optic discs for pallor; classic for optic atrophy. PMC

4. Family pedigree assessment: Mapping who is affected helps recognize autosomal-recessive, dominant, or X-linked patterns that guide genetic testing. NCBI

B) Manual/bedside tests

5. Tuning-fork tests (Rinne/Weber): Differentiate sensorineural from conductive hearing loss; in ANOA, tests suggest neural involvement. PMC

6. Ishihara color plates: Quick screening for color vision loss, common in optic nerve disease. PMC

7. Confrontation visual fields: Bedside screening that may hint at a central/cecocentral scotoma seen in optic neuropathies. PMC

C) Laboratory & pathological (including genetics)

8. Targeted next-generation sequencing panels: Test genes known to cause the phenotype (TMEM126A, OPA1, AIFM1, and others). Finding a pathogenic variant confirms the cause and inheritance. NCBI

9. Whole-exome/genome sequencing: Considered when panel testing is negative; helps detect new or rare genes (e.g., FDXR, TWNK). BioMed Central

10. mtDNA analysis (copy number/instability): Looks for mitochondrial DNA abnormalities when nuclear testing is unrevealing but suspicion remains high. (Rationale from mitochondrial AN literature.) PMC

11. Serum lactate or metabolic screens: May be normal, but supportive if elevated in mitochondrial disorders. (General mitochondrial ANSD framework.) PMC

D) Electrodiagnostic (ear and eye)

12. Otoacoustic emissions (OAEs): Often present in auditory neuropathy, showing that outer hair cells work even though hearing is impaired. PMC

13. Auditory brainstem response (ABR): Typically absent or severely abnormal in auditory neuropathy, proving a neural transmission problem. PMC

14. Electrocochleography (ECochG) / cochlear microphonic: Can demonstrate preserved cochlear microphonic with impaired neural response, supporting the AN diagnosis. PMC

15. Auditory steady-state responses (ASSR) & speech tests in noise: Quantify hearing at different frequencies and real-world speech understanding problems. PMC

16. Pattern electroretinogram (pERG): Assesses retinal ganglion cell function; often reduced in optic neuropathies. (Reported across DOA literature.) PMC

17. Visual evoked potentials (VEP): Measure the brain’s response to visual stimuli; latency/amplitude changes support optic nerve dysfunction. (DOA+ cohorts.) PMC

E) Imaging

18. Optical coherence tomography (OCT): Non-invasive retinal scan that shows thinning of the retinal nerve fiber layer, an objective marker of optic atrophy. (Common in OPA1 studies.) PMC

19. MRI of brain/optic pathways: Rules out other causes; often normal or subtly abnormal in genetic ANOA, but essential to exclude compressive/inflammatory disease. JAMA Network

20. Diffusion or tract-focused MRI (selected cases): Research-level tools can evaluate white-matter tracts of auditory/visual pathways if standard MRI is unrevealing. (General neuro-imaging approach from case literature.)

Management overview

There is no proven curative drug for the optic atrophy or the auditory neuropathy components. Care focuses on accurate diagnosis, early hearing rehabilitation (often cochlear implants for AN), low-vision care, environmental and educational supports, and genetic counseling. Cochlear implantation (CI) can provide speech perception benefits comparable to typical sensorineural hearing loss in many children with AN, though outcomes are influenced by site of lesion and cochlear nerve integrity; when the cochlear nerve is absent or severely dys-synchronized, an auditory brainstem implant (ABI) may be considered. For vision, low-vision rehabilitation and assistive technology are mainstays; idebenone has shown limited/experimental signals in DOA and is not a standard of care. ADOA+5ASHA Publications+5PubMed+5

Non-pharmacological treatments (therapy & others)

Each item includes: description, purpose, mechanism (how it helps). These are supportive/rehabilitative; they do not “cure” the disease.

1. Early family-centered hearing habilitation: Structured listening-language therapy starts as soon as AN is confirmed, with close tracking so ineffective hearing-aid trials are not prolonged. Purpose: build speech/language and auditory attention. Mechanism: intensive, consistent auditory-verbal input leverages neuroplasticity while definitive device decisions (e.g., CI) are made. PubMed

2. Cochlear implantation candidacy work-up & counseling: Multidisciplinary evaluation (audiology, imaging, neural response telemetry) to judge if CI is likely to provide synchronized neural firing. Purpose: select best candidates and set realistic expectations. Mechanism: CIs bypass inner hair cell synapse dysfunction, directly stimulating spiral ganglion neurons; success depends on nerve integrity. PubMed+1

3. Auditory brainstem implant (ABI) consideration: For absent/hypoplastic cochlear nerve or failed CI. Purpose: provide auditory sensations when cochlear nerve cannot be stimulated effectively. Mechanism: electrode array stimulates cochlear nucleus in brainstem. PubMed

13. Genetic counseling for families: Purpose: understand inheritance, recurrence risks, and testing of relatives. Mechanism: clarifies dominant vs X-linked patterns and guides family planning. NCBI

14. Orientation & mobility training (low vision): Purpose: safe travel and community participation. Mechanism: cane skills and route planning substitute for reduced visual acuity/fields. PMC

15. Workplace accommodations (captioned meetings, visual alerts, better lighting). Purpose: maintain employment and productivity. Mechanism: reduces communication barriers imposed by AN and optic atrophy. ASHA Publications

16. Tinnitus management education: Purpose: reduce distress. Mechanism: sound therapy and coping strategies reframe attention to tinnitus related to neural dys-synchrony. PubMed

17. Digital communication tools (real-time captioning, speech-to-text). Purpose: improve meeting comprehension. Mechanism: provides visual text channel when neural timing harms speech decoding. ASHA Publications

18. Low-vision driving assessments (where legal): Purpose: safety decisions and adaptations. Mechanism: standardized tests of acuity/fields and training for bioptic or cessation if unsafe. PMC

Drug treatments

Important: There is no medication proven to reverse the optic atrophy or fix the neural dys-synchrony of auditory neuropathy in ANOAS. Medicines below address co-morbid symptoms, protect general health, or are experimental/adjuncts; they should be used only under clinician guidance.

1. Corticosteroids (short courses for acute neuritis only, selected situations): Used rarely if a superimposed inflammatory optic neuropathy is suspected—not for genetic DOA/DDON/AIFM1 disease itself. Class: glucocorticoid. Dose/Time: individualized; brief. Purpose/Mechanism: reduce inflammation; not disease-modifying in DOA. Side effects: glucose rise, mood, infection risk. PMC

2. Idebenone (experimental in DOA): antioxidant used in LHON; small studies/advocacy reports suggest modest visual benefit in some OPA1 cases; not standard. Class: short-chain benzoquinone. Dose/Time: investigational regimens vary. Purpose: neuroprotection. Mechanism: shuttles electrons in mitochondrial chain, reduces ROS. Side effects: GI upset. ADOA+1

3. Co-enzyme Q10/ubiquinone (adjunct, low-certainty): sometimes tried to support mitochondrial function; evidence for DOA/AN benefit is weak. Class: supplement/antioxidant. Dose: typical 100–300 mg/day (clinical judgment). Purpose/Mechanism: electron transport support. Side effects: GI discomfort. PMC

4. Riboflavin (B2) in mitochondrial disorders (adjunct): occasionally used when broader mitochondrial disease suspected; no direct proof in ANOAS; clinician-guided. Mechanism: cofactor for flavoproteins. Side effects: harmless urine discoloration. PMC

5. Thiamine (B1) repletion if deficiency risk: protects neural metabolism; not disease-specific but correcting deficiency prevents extra injury. Side effects: rare. PMC

6. Vitamin D repletion for bone/fall risk with neuropathy/ataxia; general health measure. Side effects: hypercalcemia if excessive. PubMed

7. Neuropathic pain agents (e.g., gabapentin, duloxetine) when peripheral neuropathy causes pain/paresthesia in AIFM1/DDON cases. Class: anticonvulsant/SNRI. Purpose: symptom relief only. Side effects: sedation, nausea. PubMed

8. Muscle tone agents (e.g., baclofen) for dystonia/spasticity in DDON; symptomatic only. Side effects: drowsiness, weakness. NCBI

13. Topical ocular lubricants for comfort with visual strain; symptomatic. Side effects: minimal. PMC

14. Antioxidant mix (research/low-certainty): alpha-lipoic acid, vitamins C/E sometimes used empirically in mitochondrial optic neuropathies; benefits unproven; discuss risks. Side effects: GI upset, interactions. PMC

15. Treat acute intercurrent illnesses promptly (e.g., fever) to minimize transient AN worsening; supportive meds as appropriate. Side effects: context-dependent. PubMed

16. Ototoxicity avoidance (NOT a drug “to take” but a vital medication rule): avoid aminoglycosides and cisplatin where alternatives exist; prevents added ear damage. PubMed

17. CI-related medications (peri-operative antibiotics/analgesics) as part of implant care; standard surgical protocols. Side effects: context-dependent. PubMed

18. Tinnitus therapies may include sound therapy devices; meds are adjunct at best; strong counseling is key. Side effects: variable. PubMed

19. Vision-related low-vision aids are devices, not drugs; no eyedrops reverse optic atrophy in DOA/DDON/AIFM1 to date. Note: avoid unproven “eye vitamins” claims. PMC

20. Clinical-trial agents (future): gene therapy/cell-based and newer antioxidants are in preclinical/early stages for DOA; not clinically available yet. Use only in trials. PMC

---

Dietary molecular supplements (adjuncts only)

Evidence for disease modification is limited; use only with clinician guidance to avoid interactions.

Immunity booster / regenerative / stem-cell” drug

Reality check: There are no approved regenerative or stem-cell drugs for ANOAS. The items below summarize research directions rather than prescriptions.

1. OPA1 gene therapy (preclinical/early translational): Aim is to deliver functional OPA1 to retinal ganglion cells to slow optic atrophy; hearing targets are further off. Dosing/regimen not established. Mechanism: gene replacement to restore mitochondrial fusion. PMC

2. Cell-based retinal ganglion support (experimental): Stem-cell-derived trophic support for optic nerve; currently lab/animal work. Mechanism: neurotrophic and potential cell replacement. PMC

3. Mitochondrial-targeted antioxidants (research): next-generation molecules beyond idebenone. Mechanism: reduce ROS at inner membrane. PMC

4. Apoptosis-modulating small molecules (preclinical): based on OPA1 domain-specific roles in apoptosis control. Mechanism: tilt survival signaling in vulnerable neurons. BioMed Central

5. Redox/respiratory chain enhancers (experimental): strategies inspired by AIFM1 biology to stabilize OXPHOS. Mechanism: bolster electron transport; human efficacy unknown. ScienceDirect

6. Auditory neural prostheses evolution: Improvements in ABI and CI arrays and stimulation strategies are the practical “regenerative” path today—restoring function via prosthetics rather than drugs. Mechanism: direct neural stimulation to bypass failing synapses/axons. ASHA Publications+1

---

Surgeries

1. Cochlear Implant (CI): Electrode in the cochlea to stimulate auditory nerve fibers directly. Why: Many patients with AN (including DOA+/AIFM1) gain improved speech perception with CI if the cochlear nerve is functional. ASHA Publications+1

2. Auditory Brainstem Implant (ABI): Electrode at the cochlear nucleus when the cochlear nerve is absent or nonfunctional or when CI fails. Why: Provides access to sound when synchronized cochlear nerve firing cannot be achieved. PubMed

3. CI revision/explant/re-implant (selected cases): Why: address device failure, migration, or to take advantage of newer arrays if outcomes lag. Frontiers

4. Strabismus surgery (only if significant ocular misalignment coexists): Why: improve binocular alignment and comfort; does not treat optic atrophy itself. PMC

5. Cataract surgery (if clinically present): Why: reduce additional media opacity to optimize remaining retinal ganglion cell function; does not reverse optic atrophy. PMC

When to see a doctor

• Now/soon: a child with OAEs present but absent ABR or who fails newborn hearing screening irregularly; sudden drop in hearing clarity; new vision blurring or color vision loss; new imbalance, tremor, or dystonia; rapidly worsening school or work function. Early referral speeds implant candidacy decisions and access to low-vision care. PubMed+1

• Routine: ongoing follow-up with audiology (device checks, speech perception tests), ophthalmology/low-vision clinic, neurology/genetics where indicated, and rehabilitation services. ASHA Publications+1

---

What to eat and what to avoid

• What to emphasize: balanced diet rich in fruits, vegetables, whole grains, lean protein, and omega-3 sources to support general neural and cardiometabolic health; maintain vitamin D within target range; stay well-hydrated; regular meals to avoid fatigue spikes. These choices support overall health; they do not cure ANOAS. PMC+1

• What to limit/avoid: smoking, excess alcohol, unnecessary ototoxic drugs (discuss alternatives), and fad “mega-dose” supplements that can interact with medicines. Protect hearing with quiet habits and ear protection. PubMed

Frequently Asked Questions

1. Is there a cure? Not yet. Treatment focuses on hearing implants/rehab, low-vision care, and support. Research is active in OPA1 gene and cell-based therapies. PMC

2. Will a cochlear implant help if I have auditory neuropathy? Many children with AN achieve speech-perception gains comparable to other implant users, especially when the cochlear nerve is intact; results vary by site of lesion. ASHA Publications+1

3. What if the cochlear nerve is damaged? An auditory brainstem implant may be considered; outcomes are more variable than CI but can provide access to sound. PubMed

4. Are hearing aids useful? In many infants/children with AN, standard hearing aids do not provide adequate speech/language development, so close monitoring and early CI referral are important. PubMed

5. Can idebenone or vitamins fix optic atrophy? Evidence is limited; some small DOA reports suggest possible visual benefit with idebenone, but it is not standard care. Supplements should be clinician-guided. ADOA+1

6. Is this inherited? Often yes. OPA1 is usually dominant; AIFM1 and TIMM8A are X-linked. Genetic counseling explains your family’s pattern and risks. PMC+2PMC+2

7. Will vision always get worse? Progression varies. Regular low-vision care and assistive tech can keep you independent even if acuity declines. PMC

8. Does noise make hearing worse? Loud noise can add cochlear damage on top of AN—protect your ears. PubMed

9. Why is speech in noise so hard? AN harms neural timing; even normal audiograms can hide severe speech-in-noise problems. Remote mics and CIs help. ASHA Publications

10. Can infections or fever change my hearing? Yes—AN symptoms can fluctuate and worsen transiently with fever/illness. PubMed

11. Are there clinical trials? Early-stage DOA research exists; ask tertiary centers and patient groups for updates. PMC

12. Is DDON the same as this syndrome? DDON (TIMM8A) is one cause of combined deafness and optic neuronopathy with additional neurologic signs; your gene result defines the exact diagnosis. NCBI

13. Will blue-light glasses help? They may reduce glare/eye strain but do not treat optic atrophy; personalized low-vision strategies matter more. PMC

14. Can I drive? Depends on visual acuity/field laws and your performance; specialized low-vision driving assessments guide decisions. PMC

15. What’s the long-term outlook? With timely CI/ABI candidacy assessment, low-vision care, and supports, many people achieve good communication and independence, though the condition remains chronic. ASHA Publications+1
