ABSTRACT
PURPOSE: To report a case of globe perforation and linear retinal tear after periocular acupuncture therapy which resulted in persistent temporal field defect with normal retinal function evidenced by multifocal electroretinogram (MERG). CASE SUMMARY: A 42-year-old female presented with decreased visual acuity and pain in her right eye after a periocular acupuncture therapy for blepharospasm. At initial presentation, the best corrected visual acuity (BCVA) was 0.08 in the injured eye and the intraocular pressure was 15 mmHg. Ultrasonography showed minimal vitreous hemorrhage and fundus examination revealed a linear retinal tear in the posterior pole sparing the macula. Consequently, barrier laser photocoagulation was performed around the lesion. The patient suffered from metamorphopsia and persistent decreased visual acuity even after 3 months. On fundus examination, epiretinal membrane with macular pucker was observed on the macula. Spectral domain optical coherence tomography (SD-OCT) revealed retinal nerve fiber layer defect with a full-thickness posterior wall tear. Multifocal electroretinogram showed normal retinal function; however, Humphrey visual field test demonstrated field defect corresponding to the injury. A 25-gauge pars plana vitrectomy was performed with membranectomy and ILM peeling. One month postoperatively, improvement in BCVA and metamorphopsia was achieved; however, the scotomata remained unchanged. CONCLUSIONS: Ocular perforation or retinal tear caused by an acupuncture needle is a rare condition that has not been reported previously in Korea. Furthermore, no case of traumatic visual field defect with preserved retinal function has been reported elsewhere. Hence, the authors present a case of isolated visual field defect without retinal dysfunction following full-thickness retinal tear caused by an acupuncture needle.
