Interaction of MMP-9 in the active phase of Graves' disease with and without ophthalmopathy.

Thyroid eye disease (TED) is expressed as orbital inflammation, and serum levels of several proinflammatory cytokines have been studied among patients with Graves' disease (GD) with and without TED; however, a more sensitive and specific marker for the different phases of GD and TED is still lacking. Seventeen active TED, 16 inactive TED, 16 GD without TED, and 16 healthy controls were recruited. Serum IL-17A, MMP-2, MMP-3, and MMP-9 were measured by multiplex bead assay.

Ocular Surface Disease Related to the Inflammatory and Non-Inflammatory Phases of Thyroid Eye Disease.

Purpose: This study evaluated the ocular surface disease (OSD), especially dry eye disease (DED) parameters by combining qualitative and quantitative tools, including tear matrix metalloproteinase 9 (MMP-9), in patients with Graves' disease (GD) with and without Thyroid eye disease (TED).

Patients And Methods: A total of 17 active TED, 16 inactive TED, 16 GD without ophthalmopathy, and 16 healthy controls were included. All patients were assessed with CAS, ophthalmometry, qualitative tear MMP-9, Ocular Surface Disease Index (OSDI), ocular surface staining, Schirmer test, meibography, tear meniscus height, conjunctival hyperemia, and non-invasive tear film break-up time.
