Background
- Potentially blinding disorder
- 50% of cases associated with an underlying disorder
- RA
- Wgener's
- IBD
- Sclera fuses with the dura mater and arachnoid sheath of the opic nerve
- Explains why optic nerve edema and visual compromise are common complications
Diagnosis
- History
- Intense ocular pain that radiates to the face
- Pain with EOM (the extraocular muscles insert into the sclera)
- Photophobia
- Deep-red or purplish scleral hue
- Physical
- Essential sign is scleral edema, usually accompanied by violaceous discoloration of the globe
- The globe is tender to palpation
- Episcleral vessel dilation
- Labs (to assess possible associated disease)
- CBC
- Chemistry
- UA
- Rule-out glomerulonephritis
- ESR, CRP
- Posterior Scleritis (posterior to the insertion of the extraocular muscles)
- Physical exam often benign
- Inflammation may sometimes be seen at the extremes of gaze
- Pt c/o pain, pain upon EOM
- Involvement of the optic nerve and retina is common
- Retinal detachment, optic disc edema
- Physical exam often benign
Imaging
Ultrasound and CT can show thickening of the sclera
Treatment
- Systemic therapy with NSAIDs, glucocorticoids, or other immunosuppressive drugs
- NSAIDs
- Indomethacin 25-75mg PO TID
Dispo
- Urgent ophto consult
Complications
- Cornea
- Peripheral ulcerative keratitis > irreversible loss of vision
- Uveal tract
- Anterior uveitis seen in 40%
- Spillover of inflammation from the sclera
- Anterior uveitis seen in 40%
- Posterior segment
- Retinal detachment, optic disc edema
