Parsonage-Turner Syndrome and SARS-CoV-2 Infection: A Literature Review With Case Presentation.

Neuralgic amyotrophy, also known as Parsonage-Turner syndrome (PTS), is characterized by severe pain and muscle wasting affecting the anterior body, including the head, shoulder, upper limb, and chest wall. Often triggered by an antecedent event, such as infection, PTS encompasses various conditions historically identified as separate entities. In 1948, Parsonage and Turner unified these conditions under the term neuralgic amyotrophy based on shared features of intense pain and muscular atrophy. Recent studies have highlighted PTS as a spectrum disorder with diverse manifestations, including pure sensory neuropathy, extensive neuropathy, spinal accessory nerve involvement, and diaphragmatic palsy. We reviewed 26 documented cases of PTS following SARS-CoV-2 infection, emphasizing the importance of considering PTS in individuals with a history of COVID-19 due to varied clinical presentations. Standardized diagnostic methods and comprehensive evaluations are crucial for accurate diagnosis and management. Future research should focus on consistent evaluation methods and employing a comprehensive differential diagnosis approach.

Isolated abducens nerve palsy after closed head injury in a child.

The authors present the rare case of a 5-year-old child with an isolated right abducens nerve palsy following a minor closed head injury. Occlusion of the left eye for 4 h daily was prescribed, and the child remained under close ophthalmological follow-up. Significant improvement was noticed in the following 6 months.

Multifocal central serous chorioretinopathy associated with steroids in a patient with myasthenia gravis.

We present a case of bilateral multifocal central serous chorioretinopathy in a 40-year-old male who suffered from myasthenia gravis and was receiving oral prednisolone. Due to the severity of the underlying disease, it was not possible to reduce the corticosteroid dose. After initial unsuccessful treatment with an intravitreal injection of ranibizumab, low-fluence photodynamic therapy was performed, followed by gradual tapering of the corticosteroids. Visual acuity improved significantly in both eyes. Different therapeutic approaches are discussed.

Spectral-domain optical coherence tomography in lightning-induced maculopathy.

The authors report a case of lightning-induced chorioretinal burn accompanied by mild anterior segment injuries. Spectral-domain optical coherence tomography images were used to document the progressive retinal and choroidal changes. As evidenced by this report, despite being sight-threatening, such injuries may allow for a significant functional recovery.
