Purpose : To investigate the choroidal thickness (CT) and choroidal area (CA) in patients with unilateral commotio retinae of the macula through spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging (EDI).

Methods : This is a retrospective review of 8 patients with unilateral macular commotio retinae. Patients were examined within seven days of the blunt ocular trauma and were determined to have macular commotio retinae by exhibiting a well-defined sheen-like whitish coloration of the macula in the affected eye, differing in comparison to the contralateral non-traumatic eye in cases of unilateral trauma. All patients underwent SD-OCT with EDI. All cases did not exhibit other traumatic retinal abnormalities such as preretinal, retinal, or subretinal hemorrhages, vitreous hemorrhage, choroidal rupture, retinal tears or detachments, macular detachments, or partial- or full-thickness macular holes. Using the electronic caliper within the OCT, CT was measured from the outer portion of the hyper reflective line corresponding to the retinal pigment epithelium to the inner surface of the sclera. The average of the central horizontal and vertical raster images were used as the final CT reading of each eye. The average of the central 1,500 µm subfoveal CA of the center vertical and horizontal raster lines was used as the final CA reading of each eye. The researchers compared the CT and CA among traumatic eyes to non-traumatic control eyes as well as to best-corrected visual acuity. A paired t-test was used to compare measurements between traumatic eyes and fellow eyes in patients with macular commotio retinae.

Results : The subfoveal CT and CA in traumatic eyes with unilateral macular commotio retinae was greater (p=0.0027, p=0.0279) compared to the fellow non-traumatic eye. An increase in CT and CA in the subfoveal area due to commotio retinae was associated with worse logMAR visual acuity (p=0.0180).

Conclusions : The choroid was thicker in the subfoveal area in eyes with commotio retinae than in fellow eyes following blunt ocular trauma. Increased CT and CA in macular commotio retinae were associated with vision loss.
