We present the case of a 74-year-old man with rapidly progressive bilateral visual loss, optic disc pallor, retinal arteriolar attenuation, and an abnormal electroretinogram with a 90% reduction in cone function and a 50% reduction in rod function. He was examined for a suspected cancer-associated retinopathy (CAR). Although he was found not to have expressed the previously reported 23-kd CAR antibody, high titers were found of an antibody to a 60-kd retinal protein, which as yet remains unidentified. An initial clinical search for an underlying cancer was unsuccessful, but 2 months later a mediastinal mass was found on chest x-rays, and biopsy confirmed a diagnosis of small-cell lung carcinoma. Combined therapy with oral corticosteroids and plasmapheresis resulted in a recovery of vision from counting fingers to 20/200 in the right eye and 20/40 to 20/25 in the left eye. Conventional chemotherapeutic management of the small-cell lung carcinoma was instituted, and the modest visual recovery was maintained. The visual improvement as well as lung tumor regression were accompanied by a decline in antibody titers from 1:2,000 pretreatment to 1:200 during the course of therapy. The absence of reactivity with the previously described 23-kd retinal antigen of the CAR syndrome does not exclude the diagnosis of paraneoplastic retinopathy in patients fitting the clinical profile of this disease.

We report a 77-year-old Caucasian man with a 1-year complaint of unexplained visual loss and a 4-year history of prostate cancer. A complete ophthalmologic exam, Goldmann visual fields (GVFs), intravenous fluorescein angiography (IVFA), macular and disc optical coherence tomography (OCT), pattern-reversal visual evoked potentials (PVEPs), and flash electroretinograms (ERGs) were performed. On examination, visual acuity was reduced bilaterally. Fundus exam showed juxtapapillary changes (OS > OD) and, in OS, disc pallor, peripheral RPE dropout and whitish retinal discoloration along the arcades. OCTs were normal OU. Cancer-associated retinopathy (CAR) was suspected. A flash ERG was normal OD and markedly reduced and electronegative OS. An IVFA showed bilateral juxtapapillary staining and changes highly suggestive of sequelae of central retinal artery occlusion (CRAO) OS , in which a cilioretinal artery existed along the papillomacular bundle. GVFs showed bilateral blind spot enlargement and centrocecal scotomas, and PVEPs were delayed. These findings suggested cancer-associated optic neuropathy (CAON), confirmed by presence of anti-optic nerve autoantibodies (auto-Abs). No anti-retinal auto-Abs were found. CAON is a less common paraneoplastic manifestation than CAR and it is rarely observed in association with prostate cancer. A combination of visual function testing methods permitted the recognition, in this highly unusual case, of the concurrent presence of unilateral ERG changes most likely attributable to CRAO complications in OS, in all likelihood unrelated to CAON, and not to be confused with unilateral CAR. Auto-Ab testing in combination with visual function tests helps achieve a better understanding of the pathophysiology of vision loss in paraneoplastic visual syndromes.

We write to report a rare case of unilateral cancer-associated retinopathy previously undocumented in the literature. Cancer-associated retinopathy is an uncommon paraneoplastic syndrome. It is characterised by retinal antigen autoantibodies causing rod and cone dysfunction and abnormal electroretinography findings with consequent progressive visual loss.Our patient, known to have a primary cervical intraepithelial neoplasia, presented with unilateral blurred vision as well as a disturbance in colour and night vision. Electroretinography findings of reduced a and b waves in the right eye, together with a fundoscopic appearance of a mottled retinal pigment epithelium, attenuated blood vessels and optic disc pallor were consistent with unilateral cancer-associated retinopathy. Posterior subtenon injections of triamcinolone were administered to control active disease. With periocular steroid injections, at 4 years, our patient's visual acuity remained relatively stable and her condition persisted strictly unilaterally. Cancer-associated retinopathy may be the first presenting sign of an underlying malignancy or may indicate its recurrence. Moreover, in patients with a diagnosed gynaecological malignancy, visual symptoms could reflect cancer-associated retinopathy. In our patient visual symptoms came secondary to the diagnosis of cancer.

A total of 480 cage-cultured fish were collected from 4 coastal provinces in central Vietnam to investigate the causative agent of nocardiosis. Fish displayed unique characteristics such as paleness and lethargy and exhibited haemorrhages and ulcers on the skin. Prominent white nodules varying in size were observed in the spleen, kidney, and liver. Furthermore, histopathological sections showed typical granulomatous lesions in these organs. Using the Ziehl-Neelsen staining method, isolated bacteria exhibited acid-fast, bead-like filament morphology when cultured in brain-heart infusion medium or Ogawa medium. Phylogenetic analysis of 16S rDNA confirmed that the isolated bacterium was Nocardia seriolae. This study demonstrates for the first time an outbreak of N. seriolae in snubnose pompano in central Vietnam.
