Pterygium testing involves which procedures?

• A. NaFl and A-seg photo
• B. Visual field testing
• C. OCT
• D. IOP measurement

Answer: (A)

Evaluating pterygium centers on how far the growth extends onto the cornea and how the corneal surface is affected. Fluorescein staining highlights surface irregularities and epithelial defects, making the active margin of the pterygium more visible and helping you gauge the extent of corneal involvement. An anterior segment photograph documents the exact size, shape, and location relative to the limbus, providing a baseline for monitoring progression or planning treatment. Together, these two approaches give both the functional impact on the corneal surface and a durable record for follow-up. Visual field testing isn’t typically used to assess pterygium because the issue is localized surface involvement rather than peripheral vision loss. OCT can be informative in certain cases to evaluate related corneal thickness or to study the lesion’s depth in research or preoperative planning, but it isn’t standard for routine pterygium evaluation. IOP measurement is part of a comprehensive eye exam but does not inform pterygium assessment itself.
