Antiretina antibodies have been found in the serum samples of four patients with cancer experiencing concomitant loss of vision (cancer-associated retinopathy [CAR] syndrome). These immunoglobulins bound an antigen from normal pooled retina having a molecular weight of 23,000 daltons, which we describe as the CAR antigen. No corresponding antibodies could(More)
PURPOSE To determine long-term safety of intravitreal administration of good manufacturing practice (GMP)-grade human bone-marrow-derived CD34(+) cells in NOD-SCID (nonobese diabetic-severe combined immunodeficiency) mice with acute retinal ischemia-reperfusion injury, a model for retinal vasculopathy. METHOD Acute ischemia-reperfusion injury was induced(More)
A 61-year-old woman with progressive blindness, initially responsive to steroid therapy, was found to have an undifferentiated neoplasm in the cervix uteri. Visual fields demonstrated ring scotomas and the electroretinographic pattern eventually became flat. The interval from onset of visual symptoms to blindness was 19 months. Eye pathologic findings(More)
OBJECTIVE Our objectives were to determine what clinical characteristics are common to the form of cancer-associated retinopathy (CAR) encountered in patients with small-cell carcinoma of the lung (SCCL). Is the 23-kd retinal CAR antigen/antibody reaction present in other forms of retinopathy? Can an antigen identical or similar to the 23-kd retinal CAR(More)
Cancer-associated retinopathy is a rare paraneoplastic event that can involve allergic reactions and result in retinal degradation. A patient, who had a 35-year smoking history, complained of visual loss and was found to have serum antibodies that reacted with an extract of retina, including the previously described retinal cancer-associated retinopathy(More)
Three patients had microphthalmos with cyst in one orbit and contralateral congenital cystic eye, microphthalmos alone, or microphthalmos with cyst. Four eyes were examined histopathologically. The microphthalmic eye demonstrated a spectrum of anterior segment abnormalities, retinal disorganization and gliosis, and a choroidal and scleral colomboma. The(More)
Cancer-associated retinopathy (CAR) is a rare form of retinal degeneration that occurs in association with certain forms of cancer. CAR patients typically possess high titers of autoantibodies against a specific photoreceptor protein--the 23 kD retinal CAR antigen. The mechanisms involved in the vision loss experienced by CAR patients are not understood,(More)
In 17 patients with corneal intraepithelial neoplasia (dysplasia), the epithelium formed a gray plaque at the corneal limbus adjacent to a conjunctival papilloma in seven cases, leukoplakia in six cases, a pterygium in one case, and a pinguecula in one case. The lesion was an extension of a similar neoplastic process of the conjunctiva in 15 cases, was(More)
