Patients who undergo scleral buckling may have improvement in visual acuity, but there may be a limit to long-term improvement, according to a study.
Mikio Sasoh, MD, PhD, and colleagues retrospectively reviewed the charts of 205 eyes with retinal detachments that underwent scleral buckling. The eyes were followed for 10 years after surgery. Best corrected visual acuity and visual field were measured preoperatively, postoperatively and 10 years after surgery.
Significant increases in visual acuity were noted during the first postop year and during the next 9 years. Between the surgery and the first month postop, there was a significant increase in the area size of visual field as measured by Goldmann perimetry. After the first postop month, there were no significant change in the area size of each isopter.
The study is published in the December issue of Retina.
