Thank you for the additional information.
Ocular migraines tend to start small in the periphery, then enlarge over the next half hour, then start to fade away. Some people describe them as zig-zag lines or looking through cracked glasses
. These symptoms are not always followed by a headache. The intermittent and transient nature of your blindspot may be due to your ocular migraines. Ocular migraines do not generally need treatment unless they are frequent and bothersome to you.
Because the blindspot is not entirely typical, however, I would recommend you get a dilated eye exam to view the macula
and look for any structural causes of your blind spot.
