Advantages:

Spectral Domain Optical Coherence Tomography presents retinal architecture after scleral buckling and explains why visual acuity does not always fully recover after surgery.

Methods:

This is a single centre, prospective analysis of 132 consecutive eyes after scleral buckling, which were evaluated with SD- OCT 1, 3 and 12 months after surgery. Patients with rhegmatogenous retinal detachment with no prior surgery except phacoemulsification were included. The following data were analyzed: initial and final visual acuity, type of retinal detachment, number of procedures performed, epiretinal membrane, macular edema, photoreceptor and external limiting membrane defects, subretinal fluid, retinal pigment epithelium defects, central retinal thickness.

Effectiveness / Safety:

Mean initial visual acuity was 0.26 and mean final visual acuity was 0.32. Photoreceptor and external limiting membrane defects were present in 24% of cases. Epiretinal membranes were present in 62% of cases. Thinning of the fovea was observed in 13% of eyes. Macular edema was observed in 30% of patients after SB and in 18% of patients. Subretinal fluid was present in 30%. Mean central retinal thickness was 277um.

Take home message:

Even though various changes of retinal morphology were noted in the scleral buckling group, they did not have a statistically significant influence on visual acuity. Central retinal thickness had a tendency to normalize during the first 12 months after surgery.
