Scotoma is a localized defect in the visual field bordered by an area of the ordinary vision. A variety of eye diseases can cause scotoma including glaucoma and retinal diseases but also damage to the optical nerve.
A flashing line in eye is one of the phenomena called a scintillating scotoma (plural scotomata).
This spot is where the optic nerve and blood vesicles enter the eye and it is called the "optic disc".
It is called a scintillating scotoma, also called visual migraine or sometimes a migraine aura (because it often precedes the migraine headache in some people).It can be triggered in some people that do not have migraines by rapidly flickering lights (e.g. a computer monitor or strobe lights). Many years ago I had one after working for several hours on a bad computer monitor, the scintillating scotoma came on about 20 minutes later and I went totally blind for more than a half hour before the sparklies and zigzags began to fade.
"Scoptoma" is not a recognized medical term. It is possible that you might have meant "scotoma," which refers to a blind spot in the visual field, commonly caused by conditions such as glaucoma or migraines. If you have concerns about vision changes or blind spots, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
GlaucomaA scotoma is a loss of central vision, and there are several conditions that can cause this including multiple sclerosis, macular degeneration, methanol poisoning, stroke, nutritional deficiencies, brain tumor, hypertension, or preeclampsia, among others.

Migraine aura is the second phase of a migraine headache, between the prodrome and actual headache phases. It has a wide array of physical symptoms, but is more commonly known by the visual changes that happen to the sufferer.The migraine aura phase can include any of the body's senses and can result in:** Flashing lights, geometric patterns, tunnel vision, blurry vision, or complete greying or blacking out of vision. Numbness in the extremities, or on the side of the face the migraine is on.Weakness in limbs, impaired motor coordinationParalysis on one side of the body. (Hemiplegic migraines)ConfusionImpaired speech called aphasia (trouble finding the correct word, slurred speech or speaking in jibberish)Inability to make a decisionDizziness, vertigo, trouble with balanceSmelling something that isn't thereHearing noises such as ringing in the ears that aren't thereTasting something that isn't thereAlice in Wonderland Syndrome in which perception is changed.As stated, many people think of the migraine aura only as the visual occurrences. The visual changes are called scotoma - the word for when there is something - usually something dark, obscuring the vision of the eye. A positive scotoma would be any aura where you feel like there is actually something in the way of your vision, whether light or dark. A negative scotoma is when your eye fails to register anything - it isn't that you see black, you don't see anything in the space where it seems dark. A scintillating scotoma is the one most commonly seen - where there is flickering, flashing patterns, or at times a snow almost like the snow on an old TV set.
