![]() ![]() Moreover up to 25 percent of people who suffer a retinal detachment will have an area of lattice degeneration. While less than one per cent of those with lattice degeneration go on to have a retinal detachment the possibility is still there. Those patients who experience flashes of light have retinal holes or have significant lattice degeneration may be at a higher risk for developing a retinal detachment. ![]() The underlying cause of the condition is not known. Lattice degeneration seems to occur more frequently in patients with myopia (nearsightedness) and tends to be bilateral. The patient usually experiences no symptomsĮxcept for the rare complaint of floaters or flashes of light in the corner of the eye. Nearly all people with this condition are over 20 years old lattice lesions are thought to develop at an early age but with minimal progression. Lattice degeneration is a fairly common condition occurring in approximately 10 per cent of the population. Often the thinning becomes so profound that some patients develop retinal holes. These lesions appear as criss-crossing lines and almost always run around the circumference of the eye. Lattice degeneration presents most frequently along the superior and inferior outer edges of the retina. Although the exact cause is still unknown lattice degeneration may result from poor blood supply to the peripheral retina and/or tugging on the retina by the vitreous – the jelly-like substance that fills and maintains the eye’s oval shape. The retina is quite thin and fragile and its stability depends on interaction with other ocular structures. Lattice degeneration is the thinning and weakening of the retina the light-sensitive inner layer of the eye that receives visual images.
