###Human: Is seeing lines and web like things after an accident serious? ###Assistant: Hi. This condition is called eye floaters, this might be a benign condition but in your case, as it popped up just suddenly after eye trauma, I would be going to an eye specialist, as this might be a sign of vitreous or retinal detachment or inflammation in the posterior part of the eye. CT scan will not show anything but they need to do retinoscopy. Let me know if you have any other questions.
