Comparing the TIA, AOD500, gonioscopic grading within bilateral eyes of patients with unilateral single or double cysts or with unilateral multiple and multi-quadrants cysts

Group	Eyes and P-value	TIA (°)	AOD500 (mm)	Gonioscopic grading*
I	Eyes with cysts	15.68±7.03	0.18±0.07	1.34±0.76
	Fellow eyes	16.52±6.69	0.19±0.07	1.28±0.74
	P-value#	0.08	0.06	0.38
II	Eyes with cysts	15.63±5.72	0.18±0.07	1.33±0.88
	Fellow eyes	17.29±7.29	0.19±0.07	1.19±0.85
	P-value#	0.13	0.09	0.06
III	Eyes with more cysts	15.30±6.62	0.19±0.07	1.26±0.81
	Fellow eyes	18.08±6.96	0.22±0.08	1.02±0.70
	P-value#	0.001	0.002	0.000

Values are presented as mean±standard deviation. I: the patients with unilateral single cyst (n=96); II: the patients with unilateral double cysts (n=21); III: the patients with unilateral multiple and multi-quadrants cysts (n=42). TIA: trabecular-iris angle; AOD500 (mm): angle opening distance at 500 μm
