Short-Term Refractive Outcomes of Pseudomyopia Induced by Ocular Blunt Trauma

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. B-scan 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.
