A teenage female patient visited the ophthalmology emergency department reporting blunt ocular trauma from a stretched elastic band, accompanied by blurred vision. At presentation, uncorrected visual acuity (VA) was 6/60 in the affected eye, improving to 6/7.5 with pinhole. A slit lamp examination showed a mild anterior chamber reaction and iridoplegia with pupil shape irregularity. Gonioscopy revealed partial cyclodialysis with angle recession. Fundoscopy revealed focal commotio retinae with blot hemorrhages. Bscan ultrasonography yielded no pathology. Follow-up examination, the day after the injury, included detailed refraction, which showed a myopic shift in the affected eye. Uncorrected VA improved to 6/15 and the patient achieved 6/7.5 with correction. Clinical findings indicated myopia, which resolved within one week from the incident, and refractive error rapidly decreased to prior emmetropic values.
