All subjects underwent a scleral buckling procedure and treatment with either a transscleral diode laser or cryotherapy. Researchers designated the primary outcome measure as complete retinal reattachment at six months after a single operation. Investigators found no statistically significant difference in the primary or secondary outcome measures between the subject groups. They report a primary success rate of 83 percent vs. 92 percent in the diopexy and cryotherapy groups, respectively. Via angiography, they found CME in 12 percent of the diopexy group and 14 percent of the cryotherapy group.
Researchers further report equivalent pain and swelling one day postop.
Researchers formulated their measurements and calculations in terms of integrals and averages. They defined an integral as the area beneath the curve of peripapillary nerve fiber layer thickness, which lies along the ellipse surrounding the optic nerve head. They state that it is representative of the volume of the RNFL, while the average represents the average of all of the NFL thickness values on that curve. Researchers found a statistically significant difference in patients' pre- and postoperative RNFL values. 0.066 mm2 postoperatively.
