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.

A 44-year-old woman who showed recurrent vitreous hemorrhages with vascular tortuosity received CT angiography which revealed an internal carotid artery aneurysm. A case of internal carotid aneurysm was associated with a pattern of retinal arteriolar tortuosity pathognomic for familial retinal arterial tortuosity (fRAT), suggesting possible involvement of the cerebral circulation. We present a case of internal carotid aneurysm associated with a pattern of retinal arteriolar tortuosity pathognomic for fRAT.
