Purpose: To investigate the differences between the recurrence and cosmesis of the miniflap technique and rotational conjunctival flap technique using redundant conjunctiva tissue in pterygium patients accompanied by conjunctivochalasis.
Methods: This retrospective clinical study included 48 patients diagnosed with pterygium and conjunctivochalsis: 27 pterygium patients who underwent surgery using the miniflap technique and 21 pterygium patients who underwent surgery using the rotational conjunctival flap technique with redundant conjunctiva tissue. The recurrence of each operation, defined as fibrovascular invasion of the cornea, was analyzed. Redness was compared using Image J software to resolve the red color ratios with respect to the red, green, and blue colors of the pterygium excision site. The difference in the red color ratio before and after surgery was analyzed with each surgery.
Results: For patients who underwent the miniflap technique, the mean age was 66 years, the recurrence rate was 5.1%, the mean follow-up period was 12 months, and the average recurrence was 5 months after surgery. For patients who underwent the rotational conjunctival flap technique using redundant conjunctiva tissue, the mean age was 62 years, the recurrence rate was 5.9%, the mean follow-up period was 20 months, and the average recurrence was 5 months after surgery. The ratio of the red color after surgery decreased 5.3% in the miniflap technique group and 6.1% in the rotational conjunctival flap technique group. Between the two groups, there was no significant difference in the recurrence or redness after surgery.
Conclusions: The rotational conjunctival flap technique using redundant conjunctiva in patients with pterygium and conjunctivochalasis was useful for reducing recurrence and cosmesis.
