Study finds, Incidence and risk factors for macular oedema a
A Study was conducted to assess the incidence of cystoid macular oedema (CME) diagnosed by spectral domain optical coherence tomography (SD-OCT) after primary rhegmatogenous retinal detachment (RRD) surgery.

150 eyes of 150 patients presenting with primary RRD were included consecutively in this prospective single-centre study. SD-OCT was conducted 3 and 6 weeks after surgery.

Results:
--128 of the 150 patients completed the study, of whom 107 showed successful retinal attachment during follow-up visits.

--The most frequent operation method was scleral buckling (54.2%), followed by vitrectomy (25.2%) and the combination of both techniques (20.6%).

--Postoperative SD-OCT revealed CME, neurosensory detachment and ERM in 18.7, 31.8 and 32.7% of all cases, respectively.

--The risk of postoperative CME was significantly elevated in patients with ERM (42.9 versus 6.9%).

--In addition, patients with initial detachment of the macula had more postoperative CME (26.5 versus 11.1%).

--BCVA improvement was significantly lower in patients with CME compared to patients without 6 weeks after surgery for macula-on RRD.

Conclusively, this prospective analysis demonstrated that CME is a common consequence after RRD and that ERM and macula-off RRD were found as possible risk factors. Since CME may delay visual recovery, SD-OCT should be included in post-operational follow-ups.
