Changes in axial length after retinal detachment surgery.

Summary

Encircling with scleral buckling surgery for retinal detachment causes temporary axial eye elongation and increased corneal curvature. These changes tend to decrease over time, with males showing a greater prevalence of longer axial lengths.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Biomedical Engineering

Background:

  • Rhegmatogenous retinal detachment requires surgical intervention.
  • Encircling procedures with scleral buckling are common surgical techniques.

Purpose of the Study:

  • To evaluate changes in axial length and corneal curvature after encircling combined with segmental buckling.
  • To assess the impact of this surgical procedure on ocular dimensions.

Main Methods:

  • Prospective analysis of 74 patients undergoing retinal detachment surgery.
  • Pre- and postoperative ultrasonographic measurements of axial length and corneal curvature were compared.
  • Patient demographics (age, sex) were analyzed in relation to axial length.

Main Results:

  • A significant increase in axial eye length (median 0.77 mm) was observed one month post-surgery.
  • Corneal curvature increased by an average of 0.22 D at one month and 0.43 D at one year.
  • Males showed a higher prevalence of longer axial lengths.

Conclusions:

  • Encircling with scleral buckling induces axial elongation.
  • The procedure leads to moderate corneal curvature changes.
  • The observed ocular dimension changes are significant but tend to normalize over time.
