[Complications of dysthyroid ophthalmopathy].

The complications of dysthyroid ophthalmopathy should be known and screened in every patient since they can worsen visual prognosis and are critical to the decision for treatment. Ocular surface alteration can result from eyelid malposition, blinking deficiency, eye dryness, and proptosis. Oculomotor disorders are detected by coordimetry or a forced duction test. Optic neuropathy can be compressive or glaucomatous. Intraocular pressure elevation can result from elevation of intraorbital pressure, indentation by an enlarged muscle, or increased backflow in episcleral veins.
