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 seen within the lesion, originating from the retinal pigment epithelium. 1. The relationship between lattice-like degeneration and myopia: retinal detachment occurs mostly in myopic patients. In a larger sample of cases of hole-derived retinal detachment, there are many patients with myopic refraction of -6.00D or more. The age of onset of pore-derived retinal detachment is younger in myopic eyes than in orthoptotic eyes. In myopic eyes, the lesions are mainly in the posterior segment of the eye, starting from the equator, and the posterior segment of the eye gradually expands, the capillary layer of the choroid atrophies and thins or even disappears, the retina also degenerates and atrophies, and the vitreous liquefies. With these pathogenic factors, retinal detachment is likely to occur. 2, the impact of extraocular muscle movement: 4 straight muscle stop is located in front of the serrated edge, its movement does not have a significant impact on the retina. The oblique muscle stops at the back of the eye, and the upper oblique muscle pulls the eye downward, plus the gravitational effect of the vitreous body, which may have some relationship with the retina in the superior temporal quadrant prone to fissure. The macula is prone to cystic degeneration, which can secondary to fissure, and it is thought that it is also related to the pulling of the inferior oblique muscle during movement. Some people observed the distribution of fissures in 286 cases of retinal detachment surgery and found that 68.4% of the fissures were on the temporal side of the retina, of which 47.49% corresponded to the position of the stops of the superior and inferior oblique muscles, i.e., the fissures were in the superior temporal quadrant, mostly concentrated in the right eye at 10 to 11 o’clock and in the left eye at 1 to 2 o’clock, 13 to 15 mm after the corneal edge. In addition, large horseshoe-shaped lacunae are often found at 11 to 1 o’clock and 16 to 22 mm posterior to the corneal limbus. The fissures in the inferior temporal quadrant are more concentrated in the right eye at 8-9 o’clock and in the left eye at 3-4 o’clock, 16.46-26 mm behind the corneal limbus, with an anterior-posterior horizontal alignment. 3, the relationship between lattice-like degeneration and ocular trauma: sawtooth edge disconnection occurs after blunt contusion of the eye, which can develop into retinal detachment. The prevalence of adolescent ocular trauma in retinal detachment is high, accounting for 18.71% to 20%. Animal experiments have confirmed that eye deformation at the moment of eye contusion can cause a tear in the distal peripheral part of the retina. In addition, severe trauma can produce retinal tears directly in the equatorial region. Trauma-induced stagnation of capillary circulation in the posterior pole, retinal oscillations and vitreous traction can produce macular lacunae or develop from macular cystoid degeneration and then into holes. Except for these retinal detachments that are clearly related to trauma, in most other cases, the retina and vitreous body are already degenerated or adhered, and have the intrinsic factors of retinal detachment, and trauma only acts as a trigger to induce the occurrence of retinal detachment. 4, the relationship between lattice-like degeneration and heredity: some cases of retinal detachment occur in the same family, indicating that the disease may have genetic factors, there may be recessive inheritance or irregular dominant inheritance. Most pathological myopia has a more certain heredity and more retinal detachments occur. In addition, in patients with bilateral retinal detachment, the lesions in the fundus of both eyes are mostly symmetrical, which also suggests that some retinal detachment may be more closely related to congenital growth and development factors.
