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 4

Punctual length of both groups during followup three months.

Punctual length(In microns)	EG1, n = 25					EG2, n = 20					-value
	Mean	±SD	Median	Min	Max	Mean	±SD	Median	Min	Max
Prepunctual length	125	±37	150	102	243	155	±64	134	109	296	0.4
Punctual length after 1 month	205	±45	214	112	265	362	±185	307	165	662	<0.004
Punctual length after 3 months	189	±43	201	109	255	380	±169	308	155	652	<0.0002
value	<0.001					<0.0002

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