Summary
Scleral buckling surgery for retinal detachment can cause eye lengthening. Encircling procedures significantly increase axial length and cause myopia, unlike local buckling which has minimal effect.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Ocular Biometry
Background:
- Scleral buckling is a common surgical procedure for retinal detachment.
- Postoperative changes in ocular dimensions and refractive error following scleral buckling require detailed investigation.
Purpose of the Study:
- To investigate the changes in axial length and refractive error after different types of scleral buckling surgery.
- To compare the effects of local buckling versus encircling procedures on ocular biometry.
Main Methods:
- A prospective study involving 89 eyes from 88 patients undergoing scleral buckling.
- Eyes were categorized into four groups based on surgical technique: local buckling, encircling, encircling with vitrectomy, and encircling with local buckling.
- Axial length was measured using ultrasonography preoperatively and at 1, 3, and 6 months postoperatively. Refractive changes were also assessed.
Main Results:
- Encircling procedures (Groups 2, 3, and 4) resulted in significant axial lengthening compared to local buckling (Group 1) at 3 and 6 months.
- A significant myopic shift in spherical equivalent was observed in Groups 2, 3, and 4, correlating with axial lengthening.
- Local buckling alone caused only slight changes in axial length.
Conclusions:
- Encircling techniques in scleral buckling surgery lead to increased axial length and a myopic shift.
- Local buckling procedures have a minimal impact on axial length and refractive error compared to encircling methods.
