Table 1 Comparison of the characteristics between APACG and CPACG groups

Table 2 Comparison of the RNFL thickness between APACG and CPACG groups

Figure 1 Retinal nerve fiber layer（RNFL） thickness in OCT images．These images showed the attacked eye of a 55-yeat-old female patient with acute primary angle closure glaucoma．These images were taken at 3 days， 2 weeks， 1， 3 and 6 months after acute attack was controlled．The average RNFL （μm） thickness were 178．28 at day 3， 141．40 at week 2， 99．01 at month 1，74．04 at month 3， and 67．20 at month 6．
