  • Title: Ocular characteristics and disease associations in scleritis-associated peripheral keratopathy.
    Author: Sainz de la Maza M, Foster CS, Jabbur NS, Baltatzis S.
    Journal: Arch Ophthalmol; 2002 Jan; 120(1):15-9. PubMed ID: 11786052.
    Abstract:
    OBJECTIVES: To evaluate ocular characteristics and systemic disease associations in patients with scleritis-associated peripheral keratopathy and its different patterns, and to assess any ocular or systemic prognostic significance of the presence of the types of peripheral keratopathy in patients with scleritis. DESIGN: Review of 125 patients with scleritis alone and 47 patients with scleritis-associated peripheral keratopathy; review of patients with scleritis and the different patterns of peripheral keratopathy: peripheral corneal thinning, stromal keratitis, and peripheral ulcerative keratitis (PUK); review of ocular and systemic outcomes comparisons between patients with scleritis with and without peripheral keratopathy. RESULTS: Patients with peripheral keratopathy had more necrotizing scleritis (57%, P<.001), decrease in vision (81%, P<.001), anterior uveitis (62%, P<.002), impending corneal perforation (62%, P<.001), and potentially lethal specific-disease association (87%, P<.001) than did patients with scleritis alone. Patients with PUK had the worst ocular and systemic outcomes. Of the 24 patients with PUK, 16 (67%) had necrotizing scleritis (P =.02), virtually all had a potentially lethal systemic disease (P =.02), and all had impending corneal perforation (P<.001). CONCLUSION: The detection of peripheral keratopathy, and especially PUK, in a patient with scleritis indicates a poor ocular and systemic prognosis.
