Woman loses vision due to smartphone use

Here's a rare case of Smartphone Vision Syndrome explained by Dr Sudhir Kumar, Senior Consultant Neurologist, Apollo Hospitals, Jubilee Hills, Hyderabad.

A 30-year-old woman Manju (name changed to protect privacy) had vision problems for one and a half years. Symptoms were of seeing floaters, flashes of lights, dark zigzag lines and episodes of blurred vision, which recurred several times in the day. They would last for seconds to minutes and repeat every 10-15 minutes. In addition, she would go totally blind for a few minutes at night (on waking up in the middle of the night to use the washroom). She initially consulted an ophthalmologist who after a detailed eye check-up ruled out any eye disease. She was then referred to me to rule out any neurological cause for her vision-related symptoms. Detailed clinical neurological examination was normal and moreover, her symptoms did not point to any specific brain nerve-related disease. So, I took a detailed history.
