Abstract

Purpose

Presentation of a patient with intreacorneal foreign body, differentiation in images of corneal confocal microscopy in vivo.

Methods

The patient admitted because of suspicion of post-traumatic epithelial ingrown syndrome, to diagnosis and treatment, the following tests were performed: basic slit lamp examination, corneal scans using Scheimpflug camera (Pentacam, Oculus) and corneal confocal microscopy in vivo (Rostock Cornea Module, Heidelberg Engineering Retina tomograph III).

Results

On a slit lamp examination we described macroscopic limited opacity without evidence of inflammation. In the images from the Scheimpflug camera - hiperreflective deposits obscuring other structures of the cornea. The corneal confocal microscopy images describes post-traumatic corneal scar changes with clearly marked wound after the foreign body intake and single round conjunctival epithelial cells within the corneal stroma. In addition activation of keratocytes was observed. On about 350 microns depth, small deposits of number from few to several, with increased linear streak hyperreflexy and large, organized foreign body (piece of glass) of 1.5x0.7 mm diameter, irregular margins, with a similar hiperreflexy.

Conclusion

Corneal confocal microscopy is a useful tool for the detection and differentiation of corneal opacities of uncertain etiology.
