Abstract:
Objective:To observe the changes of corneal curvature and ocular surface after congenital ptosis.Methods:A total of 188 patients with congenital blepharoptosis were treated with frontal muscle flap suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis according to different conditions. The postoperative correction effect, corneal curvature, and ocular surface changes were observed.Results:There was no significant difference in the good correction rate among the three methods ( P>0.05). The corneal curvature at 3 months after operation was lower than that before operation and 7 days after operation ( P<0.05). The fluorescein staining score at 7 days after operation was higher than that before operation and 3 months after operation ( F=2 910.05, P<0.05). The tear film rupture time at 7 days after operation was significantly shorter than that before operation and 3 months after operation ( F=758.12, P<0.05). There was no significant difference in tear secretion test before operation, 7 days after operation and 3 months after operation ( P>0.05). The conjunctival congestion score at 3 months after operation was lower than that at 7 days after operation, and the incidence of meibomian gland dysfunction and abnormal eyelash angle at 3 months after operation was lower than that at 7 days after operation ( t=113.56, χ 2=11.02, 11.46, P<0.05). 3 months after operation, the average diopters of 3 mm and 5 mm were higher than those before operation ( t=12.35, 15.19, P<0.05). Conclusions:Frontal muscle suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis are effective in treating congenital blepharoptosis, and can effectively improve the ocular surface and corneal curvature. Clinically, the appropriate one can be selected according to the condition of the child correction method.
