Cancer-Associated Retinopathy

CAR Syndrome


  • The patient died of pneumonia 2 years after presentation.[ncbi.nlm.nih.gov]
  • A 62-year-old female patient presented to our clinic complaining of a 2 month history of shimmering photopsias and floaters.[ncbi.nlm.nih.gov]
  • This is the first reported case of SCLC-associated CAR to present with chorioretinitis.[ncbi.nlm.nih.gov]
  • CAR can present with periphlebitis and a negative-type ERG. Greater awareness of these associations may allow for earlier detection of future cases.[ncbi.nlm.nih.gov]
  • A 67-year-old woman with small-cell endometrial carcinoma suffering from deterioration of visual acuity is presented.[ncbi.nlm.nih.gov]
Short Arm
  • Using a 7 kb subclone of the human recoverin gene, a positive fluorescence in situ hybridization signal was demonstrated near the terminus of the short arm of chromosome 17 at position p13.1.[ncbi.nlm.nih.gov]
  • Invasive thymoma was considered to be the causative tumor because there had been no evidence that suggested other systemic malignancy during more than 3 years of follow-up.[ncbi.nlm.nih.gov]
  • Taken together, our present data suggest that peripheral activation of recoverin-specific antitumor CTL is likely to contribute to the preferable prognosis of CAR( ) cancer patients.[ncbi.nlm.nih.gov]
  • This strongly suggested that the 23-kDa antigen and recoverin are identical proteins.[ncbi.nlm.nih.gov]
  • Regarding antibody generation in CAR, a high incidence of aberrant expression of recoverin in cancer tissues is important, as suggested previously.[ncbi.nlm.nih.gov]
  • This suggests that anti-enolase antibodies could be responsible for the development of CAR symptoms.[ncbi.nlm.nih.gov]


Retinal Phlebitis
  • Cancer-associated retinopathy with retinal phlebitis. Y Ohnishi , S Ohara , T Sakamoto , T Kohno and F Nakao Department of Ophthalmology, Faculty of Medicine, Kyushu University, Fukuoka, Japan.[bjo.bmj.com]
  • phlebitis, Br J Ophthalmol, 1993 , vol. 77 (pg. 795 - 8 ) 11 Selective immunohistochemical staining in the paraneoplastic retinopathy syndrome, Ophthalmology, 1992 , vol. 99 (pg. 1286 - 95 ) 12 Treatment of paraneoplastic visual loss with intravenous[academic.oup.com]
  • One patient had a previous diagnosis of systemic lupus erythematosus (patient 3), two patients had a previous diagnosis of birdshot retinochoroidopathy (patients 5 and 6), and one patient had a previous diagnosis of HLA-B27-positive panuveitis and vasculitis[dovepress.com]


  • During treatment, there was progressive improvement in symptoms and the ERG normalized. Serology confirmed complete clearance of autoantibodies.[ncbi.nlm.nih.gov]
  • When cancer-associated retinopathy is suspected, a comparatively large quantity of steroids and anticancer treatment should be combined immediately.[ncbi.nlm.nih.gov]
  • Subsequent chest X-ray and CT scan showed partial regression of both primary tumor and lymph node metastasis without anticancer treatment.[ncbi.nlm.nih.gov]
  • Further understanding of CAR pathogenesis may offer potential avenues for treatment.[ncbi.nlm.nih.gov]
  • Prednisone treatment appeared to reduce the patient's antibody titers to normal levels.[ncbi.nlm.nih.gov]


  • Taken together, our present data suggest that peripheral activation of recoverin-specific antitumor CTL is likely to contribute to the preferable prognosis of CAR( ) cancer patients.[ncbi.nlm.nih.gov]
  • Various immunomodulatory therapies have also been described with varying responses, but the overall visual prognosis remains poor.[ncbi.nlm.nih.gov]
  • Despite potential options for treatment, none have demonstrated much efficacy, and the visual prognosis is typically poor.[ncbi.nlm.nih.gov]
  • Prognosis The ophthalmological prognosis varies depending on the clinical course of CAR, ranging from progressive visual loss to blindness. The overall prognosis varies depending on the type of cancer present.[orpha.net]


  • CONCLUSIONS AND CLINICAL RELEVANCE: The etiology of SARDS in dogs does not appear to be similar to cancer-associated retinopathy in humans on the basis of absence of differential antibody activity against retinal proteins.[ncbi.nlm.nih.gov]
  • Etiology The exact etiology remains unknown but an autoimmune mechanism may contribute to the development of retinal degeneration. No known genetic association has been reported.[orpha.net]

  • Etiology There has been different antibodies isolated against many specific retinal proteins: Recoverin Carbonic anhydrase II Transducin B [Alpha]-enolase TULP1 [Tubby-like Protein 1] PNR photoreceptor cell-specific nuclear receptor Heat shock cognate[eyewiki.aao.org]


  • Summary Epidemiology The prevalence is unknown but around 100 cases have been reported in the literature.[orpha.net]
  • Plasma exchange Ataxia with antibodies to CARP 8 10 Epidemiology: 1 patient; 77 year old female Clinical: Pure cerebellar syndrome Onset: 3 years after neoplasm Ataxia: Limb; Truncal; Gait; Dysarthria Ocular: Horizontal nystagmus Mental status: Normal[neuromuscular.wustl.edu]
  • Diagnosis : Interferon-associated Retinopathy Epidemiology: No age/gender predilection Pre-existing arteriosclerosis that affects microcirculation may promote development of retinopathy Signs: Cotton wool spots especially around the optic nerve Retinal[webeye.ophth.uiowa.edu]

  • Corticosteroid therapy could not prevent deterioration of visual acuity and field.[ncbi.nlm.nih.gov]
  • Corticosteroid therapy failed to prevent visual loss. She was found to possess antibodies against retinal 45 kd protein. This led to a diagnosis of cancer-associated retinopathy with atypical protein profile.[ncbi.nlm.nih.gov]
