Episcleritis: An association with IgA nephropathy

Purpose To report an unusual case of recurrent episcleritis secondary to IgA nephropathy. Design Observational case report. Methods A 39-year-old man was seen with recurrent episodes of red and painful left eye suggestive of episcleritis. Results On routine investigations the patient was found to have haematuria and proteinuria. Further investigations led to the diagnosis of IgA nephropathy on kidney biopsy. Conclusion IgA nephropathy may present with various eye signs without any other systemic clues. This case highlights the importance of some of the basic tests in clinical practice such as urine examination. This can be conveniently done with testing strip and should be considered in the routine investigation of patients with inflammatory eye diseases.
