Changes of Ocular Surface Before and After Treatment of Blepharoptosis With Combined Fascial Sheath Suspension and Frontal Muscle Flap Suspension.

OBJECTIVE

To explore the ocular surface changes after ptosis surgery in patients with severe congenital blepharoptosis.

METHODS

The patients were divided into group A and group B, Group A received conjoint fascial sheath suspension, and group B received frontal muscle flap suspension. The ocular surface changes were followed upon the 7th day and in the 1st and 3rd month after operation, which included Schirmer test (ST), break-up time (BUT), tear meniscus height (TMH). For normal distribution variables, t test was used before and after operation, and the Wilcoxon test was used for variables with abnormal distribution.

RESULTS

Compared to preoperative status, the ST and TMH were not significantly changed after surgery (P > 0.05), but BUT higher on the 7th day and in the 1st and 3rd month after operation (P < 0.05). The fluorescence staining (FL) score was higher in the 3rd month than that in the 1st month (P < 0.05), but was not significantly different between the 7th and in the 1st month after operation (P > 0.05). The ST, TMH, and BUT after surgery were not significantly different between groups of A and B (P > 0.05), but the FL score lower in the 3rd month than on the 7th day and in the 1st month after operation (P < 0.05).

CONCLUSIONS

The ST, BUT, and TMH were not significantly changed after surgery between groups of A and B, but the FL score was lower in group A than that in group B in early postoperative time.
