Shown here in this video snippet is an operculated hole in the periphery of the retina. Clearly seen is the operculum floating above the pigmented edge of the hole (a lattice spot). This hole occurred in response to a posterior vitreous separation pulling on the retina.
Holes can exist in different locations of the retina with very different consequences. The hole here does not directly affect vision and was lasered to prevent a retinal detachment. In contrast, holes in the macula (Macular holes) can cause significant visual symptoms and typically require more extensive retinal surgery to repair.
