Research output: Contribution to journalArticlepeer-review


To study magnetic resonance (MR) image findings in infectious scleritis, Gadolinium-DTPA (Gd-DTPA) enhanced MR examinations were performed in three cases of pseudomonal scleritis. There were obvious enhancement at iris, ciliary body, episcleral and inner uveal tissue adjacent to scleral lesion on post- contrast Ti-weighted chemical fat saturation images in all three cases; the scleral stroma per se remained consistently hypointense, thus resulting in a prominent ”tramline” appearance, which was not described in previous literature. Periscleral enhancement in infectious scleritis by enhanced MR image is helpful in precise localization of scleral lesion.
