Comparison of both eyes anterior segment structures of patients with unilateral blunt trauma.

ABSTRACT

BACKGROUND: To evaluate anterior segment optical coherence tomography (AS-OCT) data in patients with unilateral blunt ocular trauma (BOT), to determine the relationship of results with hyphema development. METHODS: 21 patients who received unilateral BOT were included in the study. Healthy eyes of patients were included in the control group. Iris stromal thickness (IST), schlemm canal area (SCA) and pupil diameter were measured by AS-OCT of the participants. In addition, eyes with ocular trauma were divided into those with and without hyphema and compared in terms of these parameters. RESULTS: The mean nasal and temporal (n-t) IST was measured as 373± 40 µm and 369 ± 35 µm in BOT in comparison with 344 ± 35 µm and 335 ± 36 µm in control eyes, respectively (p = 0.000 and p = 0.001, respectively). The mean nasal and temporal (n-t) SCA was measured as 12,571 ± 880 µm2 and 12,162 ± 1181 µm2 in developed hyphema in comparison with 10,455 ± 1506 µm2 and 10,188 ± 939 µm2 in did not develop hyphema, respectively (p = 0.016 and p = 0.002 respectively). CONCLUSION: The ISTs of the traumatized eyes in the nasal and temporal quadrants were statistically thicker than the other healthy eyes. SCA in both nasal and temporal quadrants of eyes with hyphema was statistically significantly larger than the group without hyphema.
