The Parinaud oculoglandular syndrome is a rare eye disease caused by different etiologic agents, including bacteria, viruses and fungi. A rare syndrome affecting conjugate vertical eye movement. Gaze palsies most commonly affect horizontal gaze; some affect upward gaze, and fewer affect downward gaze. This study was a retrospective chart review, approved by our institutional review board, and was HIPAA compliant. Furthermore, it is generally associated with bilateral. Flashcards. Parinaud Syndrome. Parinaud syndrome is classically described by the triad of impaired upward gaze, convergence retraction nystagmus, and pupillary hyporeflexia. Paralysis of upgaze: Downward gaze is usually preserved. See moreParinaud syndrome is defined as a constellation of upward gaze palsy, convergence retraction nystagmus, light-near dissociation, and bilateral lid retraction. If the findings persist for more than 6 months, the likelihood of complete resolution is very small. Parinaud oculoglandular syndrome (POGS) is a suppurative granulomatous inflammatory condition of the eye characterized by unilateral follicular bulbar or palpebral conjunctivitis and intense chemosis that often develops between 3-10 days following inoculation []. Additional symptoms of Sandifer syndrome and GERD include: head nodding. Parinaud syndrome (PS) is a collection of eye movement and pupillary response dysfunction most commonly caused by compression or lesion of the dorsal midbrain. In all cases, MRI was the investigation of choice, and histopathology always confirmed the diagnosis. g.

It is often caused by a dorsal midbrain neoplasm, commonly a pinealoma, but may also be attributable to demyelinating diseases or stroke. The affected pupils initially appear small, and are irregular, but as opposed to the tonic pupil do not maintain increased tone to near targets. Some studies have described that up to 65% of cases are due to primary midbrain lesions like strokes, hemorrhages, and neoplasms and up to 30% of cases were due to Pineal gland tumors. The term is named in honor of Henry Parinaud, a well-known French ophthalmologist and neurologist. A case of a young nurse assistant and veterinary student showing Parinaud's oculoglandular syndrome caused by the fungus Sporothrix schenkii after contamination with infected cats is reported, emphasizing the importance of laboratory investigations in cases of atypical development of the disease. , pineal gland tumors) of the dorsal midbrain.

Several cases are presented in which Parinaud's syndrome or upward gaze palsies were associated with hydrocephalus due to non-neoplastic aqueductal occlusion. Compression of the tectum, specifically the superior colliculus of the quadrigeminal plate, results in Parinaud’s Syndrome. Other atypical manifestations include neurologic syndromes (meningoencephalitis, meningitis, neuroretinitis). Compression of the superior colliculus may result in upward gaze palsy (Parinaud syndrome), and effacement of the cerebral aqueduct may lead to obstructive hydrocephalus (Figure 10.
