Rate of central corneal thickness changes in primary angle closure eyes: long-term follow-up results

BMC Ophthalmology

Table 2 Central corneal thickness change rate according the type of operation and to the presence of acute angle closure attack

	According to the type of operation
	Total	PI only	Trabeculectomy	P-value^a
CCT thinning rate	−0.72 ± 0.22 (P = 0.001)	−0.53 ± 0.25 (P = 0.034)	−1.32 ± 0.43 (P = 0.002)	0.112
	According to the presence of angle closure attack
	Total	Attack (+)	Attack (−)	P-value^b
CCT thinning rate	−0.72 ± 0.22 (P = 0.001)	−0.81 ± 0.31 (P = 0.009)	−0.63 ± 0.30 (P = 0.001)	0.680

CCT indicates central corneal thickness, PI laser peripheral iridotomy
