The wet thread was placed along the periphery of the meniscus from the apex of the anterior horn to the apex of posterior horn. The length of the thread was measured with digital Vernier Calliper (Aerospace) with accuracy 0.01 mm; the length of thread was called "peripheral length." In the same way, the inner border length was measured by placing the thread at the inner free edge of the meniscus (Figure 1).
