The symptom of crocodile tears refers to an abnormal gusto-lacrimal reflex whereby any stimulus causing parotid secretion also induces lacrimation. It is a sequelae lesion of facial nerve, usually after the facial paralysis. The authors found the symptom of crocodile tears in one case after facial paralysis due to herpes zoster oticus and two cases after Bell's palsy.

PURPOSE: To report a case of chemical injury of the cornea caused by high-dose ethanol during orbital wall fracture repair. CASE SUMMARY: A 56-year-old male presented with pain after blowout fracture repair surgery. During the surgery, 2% hexethanol solution (2% chlorhexidine and 72% ethanol mixture), which was used for disinfection of the face, flowed into the left eye. Conjunctival injection in the left limbus, a large corneal epithelial defect, and severe stromal edema were subsequently observed. The patient was treated with topical antibiotics, steroids, and autologous serum eye drops. After 1 week, the corneal epithelial defect was improved, but at the second month of therapy, recurrent corneal erosion with deterioration of the endothelial cell function occurred. Anterior stromal puncture and laser keratectomy were performed. The corneal epithelial defect and erosion improved, but the endothelial cell density was severely decreased. CONCLUSIONS: The 2% hexethanol solution is usually used for preoperative skin disinfection, but it contains a high concentration of ethanol. The surgeon should be aware that high concentrations of ethanol may result in severe corneal damage, including corneal endothelial dysfunction and limbal cell deficiency.

Purpose: We evaluated the efficacy and safety of a 0.05% cyclosporine ophthalmic nanoemulsion and a 0.1% cyclosporine ophthalmic cationic emulsion in patients with moderate-to-severe dry-eye syndrome. Methods: This was a multi-center, double-blinded, comparative, prospective, randomized clinical trial. Three ophthalmological institutions enrolled a total of 105 patients with moderate-to-severe dry eye who were randomly assigned to a 0.05% cyclosporine nanoemulsion group (the test group) and a 0.1% cyclosporine cationic emulsion group (the control group). The corneal staining scores were obtained, and the tear film breakup time (TBUT) and Schirmer test performed, at the initial visit and after 1 and 3 months of eyedrop use. The safety results were compared by recording discomfort and compliance during drug instillation. Results: The corneal staining scores and the TBUT and Schirmer test results showed that both groups showed significant improvements. The corneal staining scores significantly (and similarly) decreased in both groups. In the test group, the TBUT showed significant prolongation after 1 month of treatment and the Schirmer test score increased significantly after 3 months. Both groups reported less ocular discomfort and better compliance with drug use at 3 months than 1 month; the control group demonstrated a significant decrease in ocular discomfort at 3 months. Conclusions Both drugs improved the dry eye symptom index and relieved eye discomfort. No patient complained of serious discomfort or side-effects. The drugs were equivalent in terms of efficacy and safety.

Purpose: To report a case of paraneoplastic autoimmune retinopathy in a patient with a history of testicular cancer.Case summary: A 29-year-old man presented with photopsia and floaters. Initial fundus examination revealed no abnormal findings. However, he returned 1 month later with complaints of visual field defects. Fundus examination revealed diffuse white spots in the macula and midperipheral retina and fundus autofluorescence demonstrated hyper-autofluorescence. Optical coherence tomography showed disruption of the ellipsoid zone sparing the fovea. Visual field examination revealed peripheral visual field defects and an electroretinogram showed reduced rod and cone cell responses. Considering his history of testicular cancer, serum paraneoplastic autoantibody panel testing was performed which revealed borderline levels of anti-recoverin antibody leading to a diagnosis of paraneoplastic autoimmune retinopathy. The patient was treated with oral steroids and mycophenolate mofetil for 1 year. However, there was no improvement in the subjective symptoms or ophthalmologic findings. Conclusions This case of paraneoplastic autoimmune retinopathy in a young man with a history of testicular cancer highlights an early clinical presentation of the disease. It is crucial to recognize that the initial clinical presentation of autoimmune retinopathy can be nonspecific.

Gadoxetic acid-enhanced magnetic resonance imaging (MRI) has been widely used to detect and characterize focal hepatic lesions. Because gadoxetic acid is a hepatocytespecific contrast agent, its patterns during hepatobiliary phase enhancement provide useful information for differential diagnoses of focal hepatic lesions. Hepatic angiomyolipoma (AML) is a rare mesenchymal hepatic neoplasm composed of blood vessels, epithelioid cells, and varying amounts of adipose tissue components. Hepatic AMLs usually show marked hypointensity during the hepatobiliary phase of gadoxetic acid-enhanced MRI as hepatic AMLs are devoid of hepatocytes and fibrotic components. The present study describes a patient with hepatic AML and an atypical imaging feature. This tumor showed hyperintensity during the hepatobiliary phase of gadoxetic acid-enhanced MRI, mimicking hepatocellular tumors such as hepatocellular adenoma. The hepatobiliary hyperintensity of this lesion was likely due to multifocal entrapped hepatocytes resulting from an intrasinusoidal growth pattern of tumor cells and insufficient hepatic parenchymal enhancement during the hepatobiliary phase of gadoxetic acid-enhanced MRI.
