Evaluation of Lacrimal Punctal Changes by Anterior Segment Optical Coherence Tomography after Punctal Dilation Versus Punctal Plug Insertion in Cases of Inflammatory Punctual Stenosis

Table 3

Outer punctual Diameter of both groups during followup three months.

Punctual diameter (In microns)	EG1, n = 25					EG2, n = 20					value
	Mean	±SD	Median	Min	Max	Mean	±SD	Median	Min	Max
Pre punctual diameter	325	±120	290	149	542	469	±119	402	119	989	0.4
Outer punctual diameter after 1 month	402	±124	393	214	569	744	±224	742	310	1001	<0.001
Outer punctual diameter after 3 months	391	±122	373	200	551	692	±226	724	300	960	<0.007
value	<0.007					<0.003

value calculates the significant difference of the punctual diameter between the two groups and was calculated by Mann–Whitney U test. value calculates the significant difference in punctual Diameter group A and group B before treatment and three months after treatment in each group and was calculated by Wilcoxon Signed Ranks Test.
