Bilateral Acute Depigmentation of the Iris: Findings in Anterior Segment Swept-Source Optical Coherence Tomography.

Objective

To describe the clinical and Anterior Segment Swept-Source Optical Coherence Tomography (AS-SS OCT) findings in Bilateral Acute Depigmentation of the Iris (BADI).

Design

Retrospective descriptive study of three clinical cases.

Results

Three women diagnosed with BADI shared a history of bacterial infections treated with moxifloxacin. The AS-SS OCT showed damage from the collarette to the root of the iris, without affecting the pupillary area. In the affected areas, the anterior edge had lost its homogeneous hyper-reflectivity. The stroma was thinned and showed a patchy and diffused hyper-reflectivity. The pigmentary epithelium appeared unaffected.

Conclusions

AS-SS OCT findings, not previously described, locate the damage in BADI in the anterior edge and iridian stroma, areas which are rich in melanocytes and permeable to aqueous humor.
