Lattice degeneration is most closely associated with retinal detachment. The resulting retinal fissures account for 40% of eyes with foraminogenic detachment, and lattice-like degeneration is present in approximately 7% of normal eyes. Most often seen between the equatorial portion of the temporal or superior temporal quadrant and the serrated edge, it is pyknotic or striated, with the long axis parallel to the serrated edge. The retina within the lesion thins and has many white lines that are interlaced and arranged in a lattice pattern. These lines are actually occluded or terminal vessels with white sheaths. Pigment clusters are sometimes visible within the lesion and originate from the retinal pigment epithelium. So, how can lattice-like degeneration be prevented? The following are preventive measures for lattice-like degeneration: 1, the eyes should not be overworked, avoid prolonged viewing of television and computers. 2, less lifting heavy objects. 3, to prevent the occurrence of myopia, avoid reading or using the eyes in places where the light is too weak or too strong. 4. Do less strenuous activities. 5.Patients suffering from myopia should have regular checkups at the hospital, especially those with bad fundus. 6.Prevent eye trauma.
