A choroidal rupture is a disruption of the continuity of the Bruch’s membrane and the retinal pigment epithelium, most commonly associated with blunt ocular trauma. It occurs in 5–10% of patients after globe injury, more frequently in men and during work-related activities or physical exercises. A 21-year-old patient presented to the Emergency Department after sustaining blunt trauma to the left eye caused by being struck with a mobile phone. On admission, best-corrected visual acuity (BCVA) was 0.01, and intraocular pressure was 39 mmHg. Ophthalmic examination revealed subluxation of the crystalline lens, prolapse of the vitreous body into the anterior chamber and a choroidal rupture. Flash visual evoked potentials (VEP) showed normal latencies. However, the amplitude in the left eye was reduced to 50%. Fundus examination of the left eye demonstrated a rupture with displacement of the vascular bundle, signs of fibrosis, retinal hemorrhages, choroidal rupture, post-hemorrhagic vitreous opacities and macular edema. Fluorescein angiography revealed preserved flow in the major vessels, an area of hypo- and hyperfluorescence in the peripapillary region and scattered foci of blocked fluorescence inferiorly corresponding to dispersed hemorrhages. Based on the clinical presentation and ancillary test results, systemic and topical treatment was initiated, resulting in clinical improvement. Visual acuity remained at 0.01, while intraocular pressure decreased to 16 mmHg following pharmacological therapy. Post-traumatic choroidal rupture frequently coexists with other ocular structural injuries. It requires comprehensive diagnostic evaluation and management and the prognosis depends on the location and extent of the lesions as well as appropriately selected pharmacotherapy.
