Adie's tonic pupil after COVID-19: a case report and literature review.

Objective: Various neurological complications have been reported after COVID-19. The study aimed to document an unusual case of Adie's tonic pupil following COVID-19. Methods: The study was a case report. Results: A 28-year-old female had suffered a flu-like disease about 2 months before and the SARSCoV-2 polymerase chain reaction test at that time was positive. Two weeks after infection she noticed an asymmetry between the pupils. The only pathological finding on examination was anisocoria with a larger left pupil in ambient light. Light reflexes were observed in the right eye, while in the left eye, they were absent. Also, there was no near response in the left pupil. A 0.1% pilocarpine test results validated Adie's pupil diagnosis. After one year of follow-up, the anisocoria decreased but did not completely recover. Discussion: COVID-19 may cause damage to neural structures due to autoimmune ways by activating immune pathways or because of vascular complications that may affect the vasa nervorum. Adie's tonic pupil is often idiopathic, but it may develop following viral infection. Conclusions: Ocular complications that involve pupil abnormalities may manifest following COVID-19. In the cases of Adie's tonic pupil, infectious diseases, including COVID-19, should be questioned. Abbreviations: RT PCR = reverse transcription polymerase chain reaction.

Ross syndrome with chronic cough and RF positivity: a case report.

Ross syndrome is a rare disorder of unknown etiology, characterized by the triad of segmental anhidrosis, tonic pupil, and areflexia/hyporeflexia. Ross syndrome is thought to be a limited and selective ganglioneuropathy. Its etiology has not been fully elucidated. Autonomic findings may also accompany. We wanted to present our 25-year-old patient who was diagnosed with Ross syndrome and presented with complaints of inability to sweat, heat intolerance, headache, diarrhea and chronic cough. Keyword: cough, tonic pupil, anhidrosis, compensatory.

Photophobia as a Presenting Feature in Adie's Tonic Pupil.

A 34 years old female presented with complains of photophobia since 6-7 months. On examination, she had anisocoria of 4 mm in room light which increased in bright light. The left pupil was dilated and unresponsive to direct and indirect light stimuli. It did however, constrict slowly on near fixation followed by slow redilatation on distance fixation. A diagnosis of Adie's tonic pupil was made since left pupil constricted with instillation of dilute pilocarpine 0.1%. Her symptoms of photophobia and blurred vision immediately resolved. Photochromatic glasses and dilute pilocarpine 0.1% three times a day were prescribed. Prompt symptomatic relief of photophobia and blurred vision was observed.

Acute Oropharyngeal Palsy Following Bilateral Adie's Tonic Pupils Associated with Anti-GT1a and GQ1b IgG Antibodies.

A 36-year-old man was admitted to our hospital with complaints of dysphagia and photophobia. A neurological examination showed oropharyngeal palsy and bilateral mydriasis with loss of light reflexes in the absence of external ophthalmoplegia. Bilateral pupils were supersensitive to pilocarpine 0.1%, which was compatible with Adie's tonic pupils. Serum IgG reacted with GQ1b, GT1a, GalNAc-GD1a, and GD3. Intravenous high-dose immunoglobulin therapy improved his neurological symptoms within three weeks. To our knowledge, there is no medical literature describing acute oropharyngeal palsy with Adie's tonic pupils. We recommend evaluating antiganglioside antibodies to clarify the cause of oropharyngeal palsy and Adie's tonic pupils.

Tonic pupil after COVID-19 infection.

The latest global health threat is the ongoing outbreak of respiratory disease, which was named COVID-19 and multiple ever-evolving neurological complications have since been reported. We present the case of a patient with a bilateral tonic pupil in the postinfectious context of COVID 19. Brain magnetic resonance imaging and laboratory tests were normal, a 0.125% pilocarpine test confirmed the diagnosis.

Tonic Pupil Following COVID-19.

ABSTRACT: A 37-year-old patient presented to our emergency department with sudden onset decreased vision with a history of being treated for COVID 19 3 weeks earlier. On examination, she was found to have a tonic right pupil, which was confirmed with a dilute pilocarpine test. As tonic pupils are known to be caused by neurotropic viruses and our current understanding of the SARS-CoV-2 is that it does affect the nervous system, we feel that the tonic pupil in our patient may be secondary to COVID 19.

Tonic pupil caused by adenoid cystic carcinoma versus postradiation changes to the ciliary ganglion.

A tonic pupil, without other features of an oculomotor neuropathy, is due to a lesion in the ciliary ganglion or short ciliary nerves. Here, we present a case of a tonic pupil in a woman with radiation-treated adenoid cystic carcinoma of the nasopharynx with perineural spread and skull base involvement. This a rare case of a tonic pupil caused by direct invasion of the ciliary ganglion or postradiation effects.

PUPILLOTONIA AND ADIE SYNDROME.

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.

[Clinical presentations of Ross syndrome have changed in their lateralities following the anteriotemporal lobectomy for refractory focal epilepsy].

We describe a 60-year-old woman with medically refractory left mesial temporal lobe epilepsy accompanied by Ross syndrome. The patient had a partial triad of Ross syndrome with hypohydrosis only on her right side (contralateral to the epileptic seizure focus), Adie's tonic pupil on the right, and areflexia while her seizures used to be medically refractory. However, her hypohidrosis and Adie's tonic pupil have completely changed in terms of laterality following nearly complete seizure freedom resutling from left temporal lobectomy. This unique change in laterality in Ross syndrome is most likely caused by remote effects of the near-absent epileptic acitivity, and it also may contribute to understanding the pathophysiological mechanism of Ross syndrome.

Tonic pupils: an unusual autonomic involvement in chronic inflammatory demyelinating polyneuropathy (CIDP).

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neuropathy which affects mainly large myelinated axons and has a typically mild autonomic dysfunction mainly from postganglionic nerve fiber involvement. CASE REPORT: We report here an acute onset CIDP initially diagnosed as Guillain-Barré syndrome (GBS), unresponsive to treatment with intravenous immunoglobulin (IVIg), which later responded to plasmapheresis and corticoids. The patient had a markedly distal demyelination, prominent cranial nerve involvement and, interestingly, bilateral fixed dilated pupils. Despite complete clinical recovery, this neurological sign remained. CONCLUSIONS: Tonic pupils have previously been described in different neurologic conditions, including GBS, but not yet in acute onset CIDP or in variants with predominantly distal demyelination. It differs from the classical Adie's pupil because it lacks the light-near dissociation. This case report expands the range of possible autonomic signs in acute onset CIDP, which could help physicians establish optimal treatment strategies earlier on.

Congenital Tonic Pupils Associated With Congenital Central Hypoventilation Syndrome and Hirschsprung Disease.

Autonomic dysfunction can be associated with pupillary abnormalities. We describe a rare association of tonic pupils, congenital central hypoventilation syndrome, and Hirschsprung disease in a newborn with a mutation in the PHOX2B gene, a key regulator of neural crest cells. Hirschsprung disease is characterized by the congenital absence of neural crest-derived intrinsic ganglion cells. Tonic pupils may result from an abnormality of the ciliary ganglion, another structure of neural crest origin. The close association of these conditions in this child suggests a common abnormality in neural crest migration and differentiation.

Unilateral Adie's Tonic Pupil and Viral Hepatitis - Report of Two Cases.

INTRODUCTION: Adie's (tonic) pupil is a neuro-ophthalmological disorder characterized by a tonically dilated pupil, which is unresponsive to light. It is caused by damage to postganglionic fibers of the parasympathetic innervation of the eye, usually by a viral.or bacterial infection. Adie's syndrome includes diminished deep tendon reflexes. OUTLINE OF CASES: We report data of a 59-year-old female with unequal pupil sizes. She complained of blurred vision and headache mainly while reading. She had a 35-year history of hepatitis B and liver cirrhosis. On exam, left pupil was mydriatic and there was no response to light and at slit lamp we saw segments of the sphincter constrict. We performed 0.125% pilocarpine test and there was a remarkable reduction of size in the left pupil. The second case is a 55-year-old female who was referred to the University Eye Clinic because of a headache and mydriatic left pupil. She had diabetes mellitus type 2, as well as hepatitis A virus 20 years earlier. On exam, the left pupil was mydriatic, with no response to light. Test with diluted pilocarpine was positive. Neurological examinations revealed no abnormality in either case so we excluded Adie's syndrome. CONCLUSION: Adie's tonic pupil is benign neuro-ophthalmological disorder of unknown etiology. Most patients commonly present no symptoms and anisocoria is noticed accidentally. Although the etiology is unknown, there are some conditions that cause tonic pupil. It may be a part of a syndrome in which tonic pupil is associated with absent deep tendon reflexes.

Phacoemulsification with implantation of Morcher aniridia capsular rings for postoperative atonic pupil after iridencleisis--case report.

INTRODUCION: Large iris defets, anirdia or wide atonic pupil may cause disturbing photoptic phenomena my require surgical treatment. In acquired iris defects, ophthalmologists have a relatively wide choice of therapeutic strategies, which depend on the size and etiology of the defect and the comorbidities. The goal of treatment is to restore iris diaphragm and to reconstruct the pupil in order to prevent glare and to increase the quality of perceived image. CASE REPORT: We present a case of cataract and unilateral wide, atonic pupil in a patient 39 years after iridencleisis, who complained of intense glare in the left eye and photophobia ever since. The patient was successfully treated by phacoemulsification through a 2.75 mm clear corneal incision with implantation of two black Morcher aniridia capsular rings. The patient experienced a significant improvement in her subjective quality of vision and a constant glare that she had been experiencing for years resolved. CONCLUSION: The presented case indicates that Morcher aniridia capsular rings may be a good tool instrument to assist the surgeon in cases of cataract concomitant with wide and atonic pupil. Using these rings reduces glare and improves the subjective quality of patients' vision.
