AOA's Seolhyun updated fans about her eye condition.

Previously, Seolhyun worried fans with her social media post, writing, "The reality in front of me looks like a video call on unstable wi-fi. Does anyone know what this is?" 

Some responded that it may be a condition like astigmatism or even a symptom of hunger, but Seolhyun shared on her Instagram story, "I have otolithiasis, everyone." She added, "If you're experiencing the same symptoms as me, go to an otolaryngologist." Otolithiasis is an inner ear issue that causes repeated episodes of vertigo lasting for seconds.

Stay tuned for updates on Seolhyun.
