The aim of the work is to approach the examination of the pupil with a focus on anisocoria, its characteristics and approach to the diagnosis of pupillotonia and Adie's syndrome and its clinical evaluation. Pupil function is important not only in neurophthalmological examination but also in general ophthalmological examination. First of all, we need to know how the reflex arc works in order to be able to exclude or confirm whether the parasympathetic or sympathetic is affected. It is also necessary to know the exact characteristics of the pupil, such as size, shape, placement, function and reaction to light and at close range. Only on this basis can we distinguish pathological features. We do not often encounter this diagnosis, but it is necessary to keep it in mind, especially in the field of neurophthalmology but also in general ophthalmology. We also present three cases of pupilotonia and Adie's syndrome, which we diagnosed at the Department of Ophthalmology, Faculty of Medicine, Comenius University, after the patient himself came by emergency admission or was sent directly to ophthalmology clinic. In the discussion, we present various other diagnoses, where the reflex arc may not be affected, but the pathological pupil is caused by intraocular tumors, general systemic diseases and, last but not least, local therapy or alkaloids.

Review
Adie's pupil, also called tonic pupil, is mainly seen in young women. Most patients have unilateral eye involvement. The pupil of the affected side is significantly larger than that on the healthy side. The direct and indirect light reflection from the pupil on the affected side disappears. The pupil on the affected side is sensitive to low concentrations of pilocarpine. The pathogeneses of Adie's pupil are complex, some of which are insidious and lack corresponding specific diseases. Through a literature review, we found that Adie's pupil is mainly associated with infectious diseases, most commonly syphilis, followed by immune diseases and paraneoplastic syndromes. The ophthalmological symptoms and pupil abnormalities can disappear after active treatment of the primary disease. Pilocarpine can be used to treat ophthalmologic symptoms, such as blurred vision, for which patients might visit an ophthalmologist or neurologist. It is essential for clinicians to improve their understanding of the disease to avoid misdiagnosis. Differential diagnosis between Adie's pupil, oculomotor nerve palsy, anticholinergic drug overdose, Argyll-Robertson pupil, and congenital mydriasis need to be identified by the physician. Here, the clinical manifestations, pathogenesis, relationship between Adie's pupil and diseases, and differential diagnosis of Adie's pupil are reviewed.

INTRODUCTION
Anti-contactin-associated protein-like 2 (CASPR2) is classically associated with limbic encephalitis (LE), Morvan syndrome and peripheral nerve hyperexcitability (PNH). Additional clinical features have been previously recognized.
OBJECTIVE
To describe a cohort of patients with anti-CASPR2-associated neurological syndromes from a tertiary referral centre.
METHODS
Retrospective analysis of patients with positive serum anti-CASPR2 antibodies in the period between 2014 and 2021.
RESULTS
Nineteen patients were identified, 11 (57.9%) male, with a median age at symptom onset of 49.0 (31.3-63.0) years and a median time to diagnosis of 1.0 (0.0-1.8) years. The most common clinical syndromes were LE (7 cases, 36.8%), Morvan syndrome (4, 21.1%) and PNH (2, 10.5%). Six patients presented with atypical phenotypes (31.6%), comprising dysautonomia (orthostatic hypotension and Adie's Pupil), motor tics/stereotypies, obsessive-compulsive disorder, and brainstem involvement. The most common presenting symptoms were seizures (31.6%), PNH (21.1%) and cognitive dysfunction (15.8%). One LE patient had a disease duration of 2,5 years and was initially diagnosed with dementia. CSF was normal in most cases. Brain MRI showed temporal lobe hyperintensities in 4 LE cases (57.1%). All PNH cases had myokymic discharges of fasciculations in the electromyography. Two patients had associated thymoma and 1 had lung adenocarcinoma. Eight patients (42.1%) received treatment during the acute phase and 26.3% maintenance treatment. Approximately half of the treated cases improved or stabilised, with 4 (21.1%) deaths in the whole cohort.
CONCLUSION
Anti-CASPR2-associated neurological disorders may present with isolated atypical phenotypes, a slowly progressive clinical course, and with normal CSF or imaging findings.

Review
PURPOSE
To provide a summary of the neuro-ophthalmic manifestations of coronavirus disease 19 (COVID-19) documented in the literature thus far.
METHODS
The PubMed and Google Scholar databases were searched using the keywords: Neuro-Ophthalmology, COVID-19, SARS-CoV-2, and coronavirus. A manual search through reference lists of relevant articles was also performed.
RESULTS/CONCLUSIONS
The literature on COVID-associated neuro-ophthalmic disease continues to grow. Afferent neuro-ophthalmic complications associated with COVID-19 include optic neuritis, papillophlebitis, papilledema, visual disturbance associated with posterior reversible encephalopathy syndrome, and vision loss caused by stroke. Efferent neuro-ophthalmic complications associated with COVID-19 include cranial neuropathies, Miller Fisher syndrome, Adie's pupils, ocular myasthenia gravis, nystagmus and eye movement disorders. Proposed mechanisms of neurologic disease include immunologic upregulation, vasodilation and vascular permeability, endothelial dysfunction, coagulopathy, and direct viral neurotropism. When patients present to medical centers with new onset neuro-ophthalmic conditions during the pandemic, COVID-19 infection should be kept on the differential.

Review
Coronavirus disease 2019 (COVID-19) is a current pandemic caused by SARS-CoV-2 that has vastly affected the whole world. Although respiratory disease is the most common manifestation of COVID-19, the virus can affect multiple organs. Neurotropic aspects of the virus are increasingly unfolding, in so far as some respiratory failures are attributed to brainstem involvement. The neuro-ophthalmic manifestations of COVID-19 and the neuro-ophthalmic side effects of vaccination were reviewed. The major findings are that the SARS-CoV-2 infection commonly causes headaches and ocular pain. It can affect the afferent and efferent visual pathways by ischemic or inflammatory mechanisms. Optic nerve may be the origin of transient or permanent visual loss from papillophlebitis, idiopathic intracranial hypertension, or optic neuritis. Cerebrovascular strokes are not uncommon and may lead to cortical visual impairment or optic nerve infarction. SARS-CoV-2 may affect the pupillomotor pathways, resulting in tonic pupil (Adie's syndrome) or Horner's syndrome. Cranial neuropathies including third, fourth, sixth, and seventh nerve palsies have all been reported. Rhino-orbital mucormycosis superinfections in COVID-19 patients receiving steroids or other immunosuppressive therapies may result in unilateral or bilateral visual loss and ophthalmoplegia. Autoimmune conditions such as Guillain-Barré, Miller-Fisher syndrome, and ocular myasthenia have been reported.

Atypical antipsychotics are used in cardiac intensive care units (CICU) to treat delirium despite limited data on safety in patients with acute cardiovascular conditions. Patients treated with these agents may be at higher risk for adverse events such as QTc prolongation and arrhythmias. We performed a retrospective cohort study of 144 adult patients who were not receiving antipsychotics before admission and received olanzapine (n = 50) or quetiapine (n = 94) in the Michigan Medicine CICU. Data on baseline characteristics, antipsychotic dose and duration, length of stay, and adverse events were collected. Adverse events included ventricular tachycardia (sustained ventricular tachycardia attributed to the medication), hypotension (systolic blood pressure <90 mm Hg attributed to the medication), and QTc prolongation (QTc increase by ≥60 ms or to an interval ≥500 ms). Twenty-six patients (18%) experienced an adverse event. Of those adverse events, 20 patients (14%) experienced QTc prolongation, 3 patients (2%) had ventricular tachycardia, and 3 patients (2%) had hypotension. Patients who received quetiapine had a higher rate of adverse events (25% vs 6%, p = 0.01) including QTc prolongation (18% vs 6%, p = 0.046). Intensive care unit length of stay was shorter in patients who received olanzapine (6.5 vs 9.5 days, p = 0.047). Eighteen patients (13%) had their antipsychotic continued at discharge from the hospital. In conclusion, QTc prolongation was more common in patients treated with quetiapine versus olanzapine although the number of events was relatively low with both agents in a CICU cohort.

Review
Harlequin syndrome is a rare condition, presenting with unilateral facial flushing and hyperhidrosis in response to physical exercise, heat or emotional stressors and has scarcely been reported in pediatric patients. It is caused by a dysfunction of vasomotor and sudomotor sympathetic fiber activity inhibiting the ability to flush on the affected side, causing the neurologically intact side to appear red. We present three pediatric cases of this uncommon syndrome, each of them of different origin and displaying distinct associated (neurological) symptoms, and review medical literature. Insight into the anatomical structure of the thoracocervical and facial sympathetic nervous system is pivotal as it dictates symptomatology. About half of Harlequin syndrome cases are complicated with ocular symptoms and a minority may be part of more extensive partial dysautonomias affecting facial sudomotor, vasomotor and pupillary responses, such as Holmes-Adie syndrome and Ross syndrome. Etiology is generally idiopathic, however, cases secondary to surgery, trauma or infection have been described. Considering its predominantly self-limiting nature, treatment is usually unnecessary and should be restricted to incapacitating cases.
