What are snowflake opacities in keratitis?
Punctate keratitis (fluffy or snowflake opacities) consists of opacities of the superficial corneal stroma (Fig. 112.7A). They can be seen by the naked eye or visualized using a slit lamp. Up to 100 or more opacities measuring 0.5 mm in diameter may be observed, and these lesions heal without scarring.
