    How to optimally treat rhegmatogenous retinal detachment

     

    However, these papers based the status of the fovea on charts or retinal drawings done by the examiner, with potential observer bias, he wrote.

    Dr. Hajari and four colleagues at Glostrup Hospital in Glostrup, Denmark sought a more definitive finding by following patients presenting with acute symptomatic primary foveola-on RRD over a 32-month period.

    They enrolled 96 eyes, of which 50 were eligible for quantitative measurement of the movement of the detachment by optical coherence tomography.

    They only documented progression from foveola-on to foveol-off in one eye. In seven others, the detachment was stable during admission.

    In the remainder, the researchers noted episodes of progression and regression, with 18% of the detachments showing a net movement toward the foveola. The amount of time since admission appeared to significantly increase the risk of progression.

    In another paper included in the thesis, first published in Acta Ophthalmologica, Dr. Hajari and his colleagues studied he Danish National Patient Registry of all Danish citizens in order to identify surgery for RRD conducted in Denmark from Jan. 1, 2001 to Dec. 31, 2009.

    They found a total of 6522 cases, of which 22% received reoperation for a redetachment. They calculated that the risk of redetachment was equal to or less than the risk of detachment in the fellow eye within a year from the surgery.

    The same was true for surgery techniques using silicone up to 1.5 years after surgery. They also found that in Denmark the need for redetachment surgery has decreased over time, and that high-volume departments have better outcomes than smaller ones.

    For the third paper included in the thesis, first published in Retina, Dr. Hajari and his colleagues looked at RRD surgeries from January 2000 to July 2011.

    They found 11,451 cases of RRD in the study period, of which 8,553 eyes in 8,081 patients were identified as having primary RRD, for an annual incidence of 13.7 per 100,000 citizens.

    Increased RRD attributed to...
