Posterior scleral reinforcement shown to slow myopia progression

Mean elongation of axial length was significantly less in young patients who underwent posterior scleral reinforcement surgery, according to a study recently published in Optometry and Vision Science.
Xue and colleagues evaluated 30 patients with high myopia. They had a mean age of 7.5 years and a mean spherical equivalent of -9.72 D, according to the study abstract.
Best corrected visual acuity, intraocular pressure, refractive errors, indirect ophthalmoscopy, B-type ultrasonography and reflected light biometry were performed on both eyes preoperatively and postoperatively. Posterior scleral reinforcement surgery was performed on only one eye per patient.
After a mean follow-up of 895 days, the researchers found that mean elongation of axial length was significantly less in the surgical eye, according to the abstract: 0.75 mm vs. 0.94 mm. The surgical effect was mild but maintained, the researchers reported. They also noted a nonstatistically significant trend of a larger surgical effect in younger patients. There were no vision-threatening complications, they noted, and the procedure was well tolerated.
“Posterior scleral reinforcement surgery was found effective in slowing down high myopic axial progression in young patients within the study period, but the size of the effect was small,” the researchers concluded.
