The eye is frequently involved in sarcoidosis. Involvement usually takes the form of an anterior or posterior uveitis. The choroiditis is more often peripheral and accompanied by inflammatory changes in the retinal veins. Sheathing of the veins can be seen and the vision might be impaired by macular oedema. The inflammatory changes might be similar to those seen in pars planitis. When the diagnosis is suspected, the conjunctiva and skin should be searched for possible nodules, which can be biopsied, and an X-ray of the chest can reveal enlargement of the hilar lymph nodes. The management of the ophthalmological problem might involve treatment with local and systemic steroids but the opinion of a physician specialising in sarcoidosis is essential and should be sought before embarking on treatment.
