Scleral imaging visualises the white outer coat of the eye to assess its thickness, shape, and any focal lesions. It is relevant in conditions affecting eye size, biomechanics, and inflammatory or tumoural processes.
Techniques
Anterior segment OCT, ultrasound, and MRI can all provide information about scleral structure, while specialised photography documents surface changes. High-frequency ultrasound is particularly useful for anterior scleral and ciliary body assessment.
- Shows focal thinning, staphylomata, or localised thickening
- Helps measure globe dimensions in high myopia or nanophthalmos
- Can reveal scleral inflammation or masses
- Choice of modality depends on the area of interest and clinical question
Clinical Uses
Scleral imaging assists in diagnosing scleritis, monitoring myopic degeneration, and evaluating scleral buckles or implants. It also supports planning for surgeries involving the sclera.
- Changes in contour can influence retinal traction and detachment risk
- Imaging helps distinguish inflammatory from degenerative thinning
- Provides baseline data before structural interventions
- Findings are interpreted alongside clinical signs of pain, redness, and systemic disease
