Case ReportsAccidental Unilateral Mydriasis from Hyoscine Patch in a Care Provider.
The hyoscine patch is effective and is frequently used in motion sickness treatment. Not uncommonly, it is used to control excessive respiratory secretions in palliative patients. Patients, healthcare workers, and caregivers who administer these may experience a benign, although worrying, mydriasis should they inadvertently rub their eye after handling the patch. ⋯ Following further history, she recalled applying a hyoscine patch to a patient in the morning. Two days later, her left pupil returned to normal size. This unique presentation of pharmacological mydriasis reinforces the importance of a detailed targeted history to avoid unnecessary investigations and anxiety, as well as the importance of informing patients, healthcare workers, and caregivers of this peculiar side-effect.

Reliability of ocular ultrasonography findings for pre-surgical evaluation in various vitreo-retinal disorders.
To find the reliability of ocular ultrasonography (USG) for pre-surgical evaluation in various vitreo-retinal conditions. ⋯ Our study highlighted that the reliability of USG findings was least in cases of trauma, hence requiring special care while reporting.

ReviewNeuro-imaging: a review for the general ophthalmologist.
The diagnosis of many neuro-ophthalmic conditions is facilitated with neuro-imaging. The two main modalities are Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). ⋯ These complexities often result in imaging studies that are either unneeded or unhelpful. The goal of this manuscript is to provide a practical set of guidelines for the general ophthalmologist of how to choose the correct parameters for neuro-imaging studies.

Case ReportsRetinal vascular patterns in adults with cyanotic congenital heart disease.
The purpose of this report is to describe retinal findings in adults with cyanotic congenital heart disease. ⋯ Increased retinal vascular tortuosity appears to be prevalent in adults with cyanotic congenital heart disease and is likely to be in response to hypoxemia and erythrocytosis. This conclusion is consistent with normalization of the retinal vascularity patterns after surgical relief of cyanosis resulting in resolution of hypoxemia and erythrocytosis.
