Comparative study between conventional scleral and suprachoroidal buckling in management of primary rhegmatogenous retinal detachment

Authors

Abstract

Aim
The aim of the work was to compare the anatomical and visual outcomes of conventional scleral buckling with suprachoroidal buckling in the management of uncomplicated primary rhegmatogenous retinal detachment with peripheral retinal breaks.
Method
A prospective randomized interventional case series of 30 cases of Primary uncomplicated rhegmatogenous retinal detachment with peripheral retinal breaks. Patients were equally distributed into two groups. Group A managed with conventional scleral buckling with 360 circumferential or Localized buckles. Group B managed with suprachoroidal buckling with injection of sodiumhyaluronate14 mg/ml into the suprachoroidal space using specially designed cannula.
Results
In group A,13 cases out of 15 achieved single-surgery attachment with success rate of 86% compared to12 out of 15 cases in group B with attachment rate of 80%. No statistical significance was found between the two groups. With respect to functional success, the visual acuity of patients of scleral buckling improved from a mean of 0.08±0.08 preoperatively to 0.33 to 0.33±0.22 postoperatively. Patients underwent suprachoroidal buckling improved from a mean of 0.12±0.11 preoperativelyto 0.36 to 0.36 to 0.36 to 0.36±0.19 postoperatively. Significant myopic shift was noted in patients of scleral buckling of mean of −2.48±0.83 D as compared with −0.58±0.56 D in suprachoroidal buckling.
Conclusion
Suprachoroidal buckling technique shows non inferior results in management of cases of Primary rhegmatogenous retinal detachment in comparison with scleral buckles, with suprachoroidal buckling less changes in refraction as compared with scleral buckles.
