This is an anatomical space, actually a “potential space”. We believe that there might be some cellular debris or other microscopic bits that are trapped in this space. Debris in this space can also be seen as moving shadows only because they are so close to the retina. The eye doctor cannot see this space or the “debris”, but it is the only explanation for the floater-like moving shadows that young people see but are not part of the vitreous humor degeneration we see as people get older. The premacular bursa is an issue mostly in young people in their teens and twenties with floater-like symptoms. These “floaters” are generally not treatable with the laser, and most sane retina specialist would not consider performing a surgical vitrectomy for this condition.
