Idiopathic panuveitis

What it is

From: Orphanet

Idiopathic panuveitis is a rare inflammatory eye disease, of unknown etiology, characterized by generalized inflammation of the uvea (iris, ciliary body, choroid), retina and vitreous with consequent ciliary spasm and posterior synechiae formation, leading to acute or chronic, unilateral or bilateral visual impairment and ocular discomfort or pain. Patients present an increased risk of development of cataracts, secondary glaucoma, cystoid macular edema and/or retinal detachment. It could potentially result in vision loss.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Abnormality of vision · Frequent (79-30%)

Abnormality of eyesight (visual perception).

Blurred vision · Frequent (79-30%)

Lack of sharpness of vision resulting in the inability to see fine detail.

Ocular pain · Frequent (79-30%)

An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) localized to the eye.

Red eye · Frequent (79-30%)

A reddish appearance over the white part (sclera) of the eye ranging from a few enlarged blood vessels appearing as wiggly lines over the sclera to a bright red color completely covering to sclera.

Vitreous haze · Frequent (79-30%)

Vitreous haze is the obscuration of fundus details by vitreous cells and protein exudation.

Reduced visual acuity · Frequent (79-30%)

Cataract · Occasional (29-5%)

A cataract is an opacity or clouding that develops in the crystalline lens of the eye or in its capsule.

Conjunctival hyperemia · Occasional (29-5%)

Dilatation of the blood vessels of the conjunctiva leading to a red appearance of the sclera.

Cystoid macular edema · Occasional (29-5%)

Cystoid thickening of the retina that takes place due to accumulation of extracellular fluid in the macula as a nonspecific response to blood-retinal barrier breakdown. Histological studies show that radially orientated cystoid spaces consisting of ophthalmoscopically clear fluid are often clinically detectable in the macula area.

Headache · Occasional (29-5%)

Cephalgia, or pain sensed in various parts of the head, not confined to the area of distribution of any nerve.

Miosis · Occasional (29-5%)

Abnormal (non-physiological) constriction of the pupil.

Photophobia · Occasional (29-5%)

Excessive sensitivity to light with the sensation of discomfort or pain in the eyes due to exposure to bright light.

Posterior synechiae of the anterior chamber · Occasional (29-5%)

Adhesions between the iris and the lens.

Vitreous floaters · Occasional (29-5%)

Deposits of various size, shape, consistency, refractive index, and motility within the eye's vitreous humor, which is normally transparent.

Which doctor should you see?

The suggested department for discussing Idiopathic panuveitis is Ophthalmology, with a ophthalmologist as the relevant type of clinician. Ophthalmologist; paediatric services for children as appropriate.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which part of the eye or visual pathway is affected?
• What change in vision requires immediate contact with the eye service?
• What are the aims and alternatives of any proposed eye treatment?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Idiopathic panuveitis. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
