In case of epibulbar pathology, what is

the importance of high resolution

ultrasound evaluation?


23/33

( ) Normal sclera is uniformly highly reflective and hasdistinct margins to the episclera and underlying uvealtissue.

( ) Episcleritis typically does not show low reflectivethickening of the episclera with normal underlyingsclera.

( ) Scleritis can be diffuse and nodular.

( ) In nodular scleritis, the scleral thickening andhyporeflectivity is not focal with distinct borders.
