Axenfeld-Rieger syndrome (ARS) is associated with ocular and systemic anomalies. PITX2 is known to be a major controlling gene in the pathogenesis of ARS and is associated with differentiation in both the neural crest and mesoderm during eye development. A 4-year-old girl with bilateral ARS had 20 prism diopters (PD) of exotropia with 30PD of A- pattern deviation, more than 20PD of dissociated vertical deviation (DVD), and severe superior oblique overaction (SOOA). During surgery we observed that the SO inserted more posteriorly than normal. We believe this finding is one of the abnormal manifestations of the development of the extraocular muscles in ARS.

PURPOSE: We report a case of visual loss after the injection of poly-L-lactic acid filler into the right forehead area for cosmetic purposes. CASE SUMMARY: A 46-year-old female patient visited our clinic due to sudden visual disturbance and dysesthesia on the right forehead and cheek. Her best corrected visual acuity was no light perception in the right eye and 20/20 in the left eye. Visual acuity in her right eye was not corrected. An afferent papillary defect in the right eye and paralysis of oculomotor muscles were observed. Fundus exam revealed a pale optic nerve and turbid retina on the posterior pole. The retinal vessels were narrowed. A papule 1 cm to the lateral margin of the right eyebrow due to the needle injection was found and no other visible skin abnormalities were observed. She had a cosmetic poly-L-lactic acid filler injection into the right forehead area immediately before the visual disturbance occurred. Fluorescent angiography showed occlusion of the right retinal artery and blood flow defects on the retina and choroid were present. The patient was followed up for 6 months and visual acuity and dysesthesia in her right forehead and cheek did not improve. CONCLUSIONS: Several cases of visual loss have occurred after injection of filler on the glabella and forehead for cosmetic purposes. However, most of the complications were observed after the use of hyaluronic fillers and not due to poly-L-lactic acid filler. This is the first case report of visual loss caused by poly-L-lactic acid filler in South Korea in a normal patient. Hence, consideration of complications when using this type of fillers is important.
