Background Commercially available cupping devices are increasingly being used for cupping therapy. However, with improper use they may induce unwanted barotrauma. Case Presentation A 6 year old child from Hong Kong applied a cupping device to her own eye. It resulted in periorbital ecchymosis and subconjunctival hemorrhage which resolved without sequaelae after a course of topical antibiotics. Conclusion This case highlights the need to raise public awareness about the proper use of cupping devices and its risk in inducing ocular injuries.
