While the data suggests we can be flexible concerning the timing of surgical repair for macula-on detachments, those involving giant retinal tears that are superiorly located and encroaching on the macula should be treated as an ocular emergency. When barriers exist to timely surgery, however, limited activity and bed rest should be considered. Some advocate occluding both eyes to limit saccadic eye movements, which can increase fluid dynamics and migration into the subretinal space.
