Abstract
PURPOSE: This study aims to determine whether elevated central macular thickness (CMT) before uncomplicated cataract surgery may be a risk factor for developing cystic macular edema (CMEs) as measured by Cirrus-OCT and defined as the presence of macular intraretinal cysts. METHODS: A prospective study in Hospital Universitario Poniente, Almeria, Spain, where 379 patients were included for optical coherence tomography (OCT) before cataract surgery, the following day, at 1 month and at 3 months and the presence of macular intraretinal cysts assessed by OCT. Patients with known risk factors for developing CME and patients who developed major surgical complications were excluded. RESULTS: One hundred seventy-nine patients completed the study. The pre-surgical CMT was 257.75 (20.60) μm measured by Cirrus-OCT. After 1 month, there was an average increase in CMT of 277.86 (45.29) μm, and this increase in thickness decreased after 3 months to an average value of 267.86 (20.17) μm. There were 10.34% of patients with cysts in some of the controls after surgery. This study proposes a binary logistic model to predict the presence of CME depending on the pre-surgery CMT. The cut-off point was 260.5 μm. CONCLUSION: Patients with pre-surgical macular thickness > 260.5 μm measured by Cirrus- OCT before cataract surgery, no known risk factors for developing CME and no major surgical complications presented 9.08 times more probability to develop macular intraretinal cysts after uncomplicated cataract surgery.
