Purpose: To analyze the corneal thickness and anterior chamber (AC) angle using anterior segment optical coherence tomography (AS-OCT) in patients with acute anterior uveitis (AAU). Methods: Twenty two patients (24 eyes) were included. All patients underwent complete ophthalmological examination, applanation tonometry and AS-OCT at diagnosis and fifteen days after treatment. Results: Average corneal thickness before treatment was 564.2 ± 44.2 µm, 580.0 ± 44.3 µm and 580.1 ± 2.9 µm, respectively in central, pericentral and paracentral cornea. Fifteen days after treatment a significant decrease of corneal thickness was observed, with 529.5 ± 33.1 µm (p=0.0091) and 542.6 ± 33.6 µm (p=0.0068), respectively in central and pericentral cornea; paracentral corneal thickness (557.8 ± 35.3 µm) thinning did not reach statistical significance (p=0.1253). There was no significant change in temporal AC angle between visits, 44.3 ± 14.4 degrees before treatment and 44.7 ± 14.7 degrees fifteen days after (p=0.9343), and mean intraocular pressure, 10.8 ± 4.5 mmHg before treatment and 12.3 ± 3.0 mmHg fifteen days after (p=0.1874). Conclusion: In the studied group, AS-OCT detected a decrease of corneal thickness after AAU treatment. Temporal AC angle and intraocular pressure did not change during the studied period.
