23.4 Case 4: Corneal infiltrate
by Prof. Renato Ambrósio Jr
A 33-year-old female presented for evaluation of a corneal infiltrate. The patient mentioned having
used tap water for cleaning her soft contact lens two days ago. Her symptoms had started after
wearing her contact lens 6 hours in OS. She woke up in the next night with moderate secretion.
She complained of photophobia and blurred vision in OS when wearing glasses. A Pentacam®
examination was performed in both eyes, revealing an infiltrate in OS, and the findings were with
correlated slit lamp biomicroscopy images (Figure 197, Figure 198).
