Parinaud syndrome is characterized by the patient’s inability to perform eye movements, especially controlling gaze in the vertical direction. He was the one who gave the disease a clear view and understanding. He was known in these fields in the second half of the 19th century. The term is named in honor of Henry Parinaud, a well-known French ophthalmologist and neurologist. ( 3, 4, 10) ConclusionĪ parinaud syndrome is an umbrella term for multiple eye abnormalities. The improvement is slow but steady, especially when proper treatment and care is observed. The overall condition of the eye usually improve after a few months. If the ocular tissues are infected, then it should be removed surgically.įor eye-related symptoms such as upgaze palsy, retraction nystagmus, and convergence movement, they can be improved using bilateral inferior rectus recessions. If there is an ongoing infection, the doctor will prescribe antibiotics. It is important to diagnose the disease at an early stage so that treatment will be initiated the soonest time possible.Ī positive prognosis for recovery is more likely to happen if the disease is diagnose and treated at an early stage. Hence, it is important to come up with a detailed diagnosis including a CT scan and MRI scan. The focus of care and treatment approach depends on the clinical manifestations and underlying cause. Young patients suffering from brain tumor in the midbrain and pineal gland.Geriatric patients, especially those with stroke of the upper brainstem.Women with multiple sclerosis, especially in their 20s to 30s.People who are at risk for parinaud syndrome include the following: There are also instances when an angiography is needed to as to detect arteriovenous malformation. The doctor will usually order for a CT scan and MRI scan. Various neuroimaging studies should be done to correctly and accurately diagnose the condition of the patient. Culture and sensitivity of the eye secretion can also help come up with the most accurate diagnosis. The cornea will also be checked for the presence of ulcers.Ī blood test is ordered to check for any signs of infection. The presence of swollen lymph nodes near the ears should be checked as well. He/she will watch for any signs of irritation and redness. The doctor will conduct a thorough physical examination of the affected eye. The bacteria causing disease can directly enter the eye or can be transmitted to the eyes via droplets. The common causes are tularemia and cat scratch disease. The source of infection is usually viral, bacterial, fungi, and parasite. However, parinaud syndrome usually affects one eye and occurs with a swollen lymph node and fever. Parinaud syndrome is commonly mistaken for conjunctivitis because the clinical manifestations are the same. Other possible causes of parinaud syndrome include the following: Parinaud syndrome is usually associated with pineal gland tumor and infarction in the midbrain. Other clinical manifestations include nerve palsy at third position, skew divergence, see-saw nystagmus (intorsion and elevation of one eye), diplopia (double vision), oscillopsia (illusion of an unstable visual world), and near vision becomes blurry.It is usually seen in patients with botched ventriculoperitoneal shunts. A portion of the lower pupil is covered by the lower lid. The eyes are driven downward and the sclera is usually positioned in between the iris and upper eyelid.
It is common in children which results from upward gaze paresis. Setting sun sign – It is also known as a sunset eye sign.If you suddenly up gaze, the eyes pull in and the globes retract. Convergence-Retraction nystagmus – An upward gaze causes this phenomenon.Collier’s sign (Eyelid retraction) – It is the abnormal elevation of the upper eyelids and lowering of the lower eyelids.The pupils respond well to near stimuli but they do not response to light. Pseudo-Argyll Robertson pupils – The pupil of the patient is mid-dilated and demonstrates a light near dissociation.The upward gaze mechanism is not functioning. Upgaze paralysis – The patient complains of upward gaze palsy.The clinical manifestations of parinaud syndrome include the following: Image Source: Parinaud Syndrome Symptoms Photo 2: A two year old patient with a clinical manifestation of parinaud syndrome.

The term parinaud syndrome is named after Henry Parinaud, a French ophthalmologist. It is a term used to denote multiple eye abnormalities, specifically dysfunctional pupil and eye movement.
