Autoimmune retinopathy represents a spectrum of retinal degenerative disorders and rare autoimmune diseases that primarily affect retinal photoreceptor function with that including paraneoplastic (PAIR) and nonparaneoplastic (nPAIR) sub­types caused by cross-reactivity of serum autoantibodies against retinal antigens and leads to progressive vision loss. In Autoimmune Retinopathy (AIR) the body’s own defence mechanism starts attacking tissues by mistake, in this case the retina, as opposed to in a genetic condition like inherited sight loss which leads to retinal degeneration. Included in this spectrum are cancer-associated retinopathy (CAR), melanoma-associated retinopathy (MAR), and presumed non-paraneoplastic autoimmune retinopathy (npAIR). Autoimmune retinopathy typically presents in the fifth and sixth decades with rapidly progressive, bilateral, painless visual deterioration. Examination of the fundus (the back inner part of the eye) is usually normal at presentation. The underlying reason for the autoimmune attack on retinal cells remains unknown. Treatment includes systemic immunosuppression with steroid and steroid-sparing agents, intravenous immunoglobulin (IVIG), and plasmapheresis (plasma exchange).
Autoimmune retinopathy represents a spectrum of rare autoimmune diseases that primarily affect retinal photoreceptor function and lead to progressive vision loss. Included in this spectrum are cancer-associated retinopathy (CAR), melanoma-associated retinopathy (MAR) and presumed non-paraneoplastic autoimmune retinopathy (npAIR). Autoimmune retinopathy typically presents in the fifth and sixth decades with rapidly progressive, bilateral, painless visual deterioration. Examination of the fundus (the back inner part of the eye) is usually normal at presentation. [1][2] The underlying reason for the autoimmune attack on retinal cells remains unknown. Treatment includes systemic immunosuppression with steroid and steroid-sparing agents, intravenous immunoglobulin (IVIG), and plasmapheresis (plasma exchange).[1]

Types

The disease may be subdivided into paraneoplastic and non-paraneoplastic AIR. When related to melanoma, it is referred to as MAR, and when related to other cancers, it is called CAR.

Cancer-associated retinopathy

A division of AIR, cancer-associated retinopathy is a paraneoplastic syndrome , which is a disorder caused by an immune system response to an abnormality. Autoimmune antibodies  attack target proteins in retinal photoreceptor cells. The proteins targeted as antigenic are recovering, may α‐enolase, and transducin.[rx] This autoimmune response leads to photoreceptor cell death in ratina.[rx] It causes progressive vision loss that can lead to blindness.[rx] CAR is typically associated with the anti-recoverin antibody.[rx]

Melanoma-associated retinopathy

Retinal bipolar cells in the retina transmit signals to react with the antibodies, leading to cell death. Although it is less prevalent than CAR, diagnosed cases of MAR continue to increase while CAR numbers decrease.[rx]

Symptoms

Both CAR and MAR share the about to same symptoms. This is because they are both paraneoplastic syndromes. AIR symptoms are numerous and shared by many other diseases.[rx]

  • Patients present with vision problem with bilateral and asymmetric scotomas, photopsia, visual field defects, with rapidly progressive visual loss in late-onset.
  • In the initial stage, fundus examination is unremarkable, and in late stages, there is limited retinal  vascular attenuation, with or without optic disc pallor, associated or not with intraocular infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation and with no evidence of degenerative retinal disease.
  • Painless Vision Loss
  • Blind Spots in Vision
  • Photopsia
  • Nyctalopia
  • Scotomas
  • Dislike/avoidance of light
  • Loss of contrast sensitivity
  • Decreased night vision
  • Subacute vision loss
  • Eye floaters or flashes
  • Blind spots
  • Decreased color vision
  • Bilateral, slowly progressive vision loss
  • Prolonged glare after light exposure
  • Decreased color perception
  • Central blindspots
  • Poor night vision

Diagnosis

Ophthalmologic and complementary examinations such as full-field electroretinogram, optical coherence tomography, visual field and fundus autofluorescence, help the diagnosis.[rx]

Diagnosis of AIR can be difficult due to indentify of symptoms with other disorders.[rx] Examination of the fundus of ratina (inner surface of eye) can show no results or it can show narrowing of the blood vessels, the abnormal color of the optic disc, and retinal atrophy with spasm.[rx][rx] Fundus examination results are not indicate of autoimmune retinopathy but they are used to initiate the diagnostic process. An electroretinogram (eye test used to see abnormalities in the retina) is used to detect AIR. An abnormal electroretinogram (ERG) with respect to light and dark adaptations indicates AIR.[rx] The ERG also allows differentiation between cancer-associated retinopathy and melanoma-associated retinopathy.[rx] If the ERG shows cone responses, CAR can be prematurely diagnosed.[rx] If the ERG shows a significant decrease in b-wave amplitude, MAR can be prematurely diagnosed.[rx][rx] To confirm, analysis for anti-retinal antibodies through Western blotting of serum collected from the patient is done.[rx][rx]

Treatment

Due to the difficulty of diagnosis, managing this disease is a challenge. For this reason, there is no established treatment for AIR. Clinicians try to reduce and control the autoimmune system attack to prevent any irreversible retinal damage.[rx] Methods of treatment include intravenous immunoglobulin (IVIG), plasmapheresis, and corticosteroids.[rx]

Immunoglobulin

Immunoglobulin samples are get from a large pool of healthy, matched donors (10000 – 20000).[rx] The immunoglobulin mixture is then administered through IV at a rate of 0.4g/kg/day for 5 days.[rx] Antibodies in the IVIG mixture interact with binding in the site of the disease-associated antibodies (such as anti-recoverin antibodies).[rx] This prevents binding to proteins targeted to disease and reduces disease activity.[rx] Responses to this treatment can vary and are effects if the patient is diagnosed with any type of cancer.[rx] Patients who respond positively improve in the clarity of their vision and their visual field.[rx]

Plasmapheresis

Plasmapheresis involves separating blood into two parts of blood cells and plasma.[11] The blood plasma components, such as the antibodies, are treated outside of the body. After removal of the disease-associated antibodies, the blood cells and plasma are transferred back into the body.[rx] Response to this treatment depends on how much and quantity retinal damage has been done. Patients who respond positively show significant visual gains.[rx]

Corticosteroids

Corticosteroids are administered through intravenous IV or orally. They cause lymphocytopenia, a condition where white blood cell levels are abnormally low.[rx] Corticosteroids cause white blood cell death, lowering their amount throughout the body.[rx] They also caused the white blood cells to recirculate away from the area of damage (the retina).[rx] This minimizes damage caused by the antibodies produced by the white blood cells. Often, this is treatment is combined with the plasmapheresis process.[rx] Instead of treating the plasma and blood cells, they are healthy donor mixture. Patients who respond positively show improved visual fields and almost complete disappearance of anti-retinal antibodies.[rx]

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

Care roadmap for: Autoimmune Retinopathy – Causes, Symptoms, Diagnosis, Treatment

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
