Posterior Scleritis





History of Present Illness


A 75-year-old female with past medical history significant for hypertension, chronic kidney disease, and a prior carotid endarterectomy of the left internal carotid presented with acute-onset blurry vision, tearing, eye pain, and redness of the right eye (OD).



Exam












































OD OS
Visual acuity 20/25−2 20/20−2
Intraocular pressure (IOP) 14 14
Sclera/conjunctiva White and quiet White and quiet
Cornea Clear Clear
Anterior chamber (AC) Deep and quiet Deep and quiet
Iris Unremarkable Unremarkable
Lens Clear Clear
Anterior vitreous Clear Clear
Posterior segment Choroidal folds Within normal limits


Because of the finding of choroidal folds, optical coherence tomography (OCT) and ultrasound were performed ( Figs. 27.1 and 27.2 ).




Fig. 27.1


Optical coherence tomography (OCT). (A) Enhanced-depth OCT of the right eye shows normal macular structure but significant choroidal thickening. (B) Enhanced-depth OCT of the left eye shows normal macular structure and normal choroid.

Ultrasonography. (A) A-scan identified scleral thickening ( yellow arrow ), whereas (B) B-scan ultrasonography identified sub-Tenon’s fluid consistent with a “T-sign” ( red arrow ) of the right eye. Left eye was unremarkable (images not shown).


Questions to Ask





  • Do you have ocular pain, with or without eye movement?



  • Do you have an associated systemic rheumatic disease, autoimmune disease, or systemic vasculitis or is there any family history of such diseases?



  • Do you have any sinus issues, including epistaxis?



  • Do you have a history of a sexually transmitted disease or exposure to other infectious diseases?



  • Do you have a history of ocular or systemic neoplastic disease?



She answers yes to ocular pain with and without eye movement. Otherwise, she answers no.


Assessment





  • Unilateral posterior scleritis OD



Systemic Disease Associations





  • Rheumatoid arthritis



  • Granulomatous polyangiitis



  • Polyarteritis nodosa



  • Ankylosing spondylitis



  • Psoriasis



  • Systemic lupus erythematous



  • Sarcoidosis



  • Tuberculosis



  • Syphilis



Differential Diagnosis





  • Choroidal tumor (melanoma, hemangioma, metastasis)



  • Orbital neoplasia (immunoglobulin G [IgG] 4–related disease)



  • Annular ciliochoroidal detachment



  • Exudative retinal detachment




    • Choroidal neovascularization (CNVM)



    • Central serous chorioretinopathy (CSCR)



    • Vogt-Koyanagi-Harada disease (VKH) (bilateral posterior scleritis)




  • Uveal effusion syndrome



Working Diagnosis





  • Idiopathic posterior scleritis OD



Testing





  • In patients with classic presentations, such as the woman described here, testing for systemic rheumatologic, autoimmune, and noninfectious diseases should be undertaken to identify potentially treatable conditions that might affect systemic health, morbidity, and mortality, as well as to exclude infectious diseases before the introduction of systemic treatment with steroids or immunomodulatory therapy (IMT).



  • For most cases check:




    • Fluorescent treponemal antibody absorption (FTA-ABS), rapid plasma reagin (RPR)



    • Purified protein derivative (PPD) or QuantiFERON gold



    • Rheumatoid factor, anti-cyclic citrullinated peptide antibody (CCP)



    • Cytoplasmic antineutrophil cytoplasmic antibodies (cANCA) and perinuclear antineutrophil cytoplasmic antibodies (pANCA) with myeloperoxidase (MPO)/proteinase 3 (PR-3) antibodies



    • Antinuclear antibodies (ANA)



    • Angiotensin-converting enzyme (ACE), lysozyme, and chest x-ray



    • HLA-B27



    • Complete blood count (CBC), complete metabolic panel (CMP)




  • Patients should be periodically asked about the development of associated symptoms, such as joint pain, sinus issues/epistaxis, shortness of breath, and skin rashes.



Management





  • Oral prednisone taper once the results of infectious laboratory tests have returned (60 mg for 2 weeks then 50 mg, 40 mg, 35 mg, 30 mg, 25 mg, 20 mg, 15 mg, 10 mg, and 5 mg for 1 week each)



  • Follow up in 1 month with repeat ultrasonography



  • Refer to rheumatology if associated systemic autoimmune disease is identified during workup



Follow-up


The patient follows up 1 month later. She reports nearly complete resolution of her symptoms. Vision is 20/25 both eyes (OU) ( Fig. 27.3 ).
