Of all the eyes, 61 (29.6%), 88 (42.7%), 40 (19.4%), and 17 (8.3%) had MAM grades of A1, A2, A3, and A4 (Figure 1 and Table 1).
Features of myopic retinoschisis in different myopic atrophy maculopathy (MAM) grades. (A) Distributions of numbers of retinoschisis layers in different MAM grades. (B) Distributions of the range and location of outer retinoschisis in different MAM grades. A1, tessellated fundus; A2, diffuse chorioretinal atrophy; A3, patchy chorioretinal atrophy; A4, macular atrophy.

A2 (54.5%), followed by A1 (50.8%). At A2, the incidence gradually declined (Figure 2 and Table 2). Both the number of retinoschisis layers and grades of outer retinoschisis presented a weakly negative association with the severity of MAM (r = -0.138, P = 0.048; r = -0.139, P = 0.047; Figure 2).
(A) The incidence of complications of myopic retinoschisis in different myopic atrophy maculopathy (MAM) grades. (B) The incidence of paravascular abnormalities in different stages of MAM. A1, tessellated fundus; A2, diffuse chorioretinal atrophy; A3, patchy chorioretinal atrophy; A4, macular atrophy.

OLMH rate reached its peak at A2 and then decreased gradually. On the contrary, the incidence of FTMH reached its minimum at A2 and then increased (Figure 3A). The prevalence of paravascular lamellar holes showed an upward trend from A1 to A4 (Figure 3B).
