'Floaters' whether they be black dots/specks or cloud like blobs that will move when your eye move are bits of your vitreous fluid. Quite common as one ages. However, if you see a sudden increase in floaters that could be the sign of a retinal tear which should be checked out by an opthamologist asap as it could lead to a retinal detachment. However, if you were checked out by a retinal surgeon and he/she spotted nothing, then you know that wasn't the case. I've had retinal tears over the years and have been told that the signs to watch out for are not only a sudden increase in floaters but what appears to be flashing lights or a partial 'curtain' falling over your vision. Regardless, these are urgent signs if it occurs and one should get themselves to an Emergency Dept where you will likely be triaged quickly and examined by an opthamologist or resident.
