Pseudophakic cystoid macular edema and spectral-domain optical coherence tomography–detectable central macular thickness changes with perioperative prostaglandin analogs

To define the incidence of cystoid macular edema (CME) and spectral-domain optical coherence tomography–detectable (SD-OCT) subclinical changes in central retinal thickness in patients using prostaglandin analog (PGA) eyedrops after phacoemulsification. Setting Manchester Royal Eye Hospital, Manchester, United Kingdom. Design Prospective case series. Methods A consecutive analysis of the incidence of postoperative CME after phacoemulsification by a single surgeon was performed in eyes of patients using PGA eyedrops between March 2010 and January 2014. The presence of CME was determined using SD-OCT (Cirrus) 3 weeks and 6 weeks postoperatively. Exclusion criteria included preexisting pathology known to predispose to CME and previous ophthalmic surgery. The paired Wilcoxon signed-rank test was used to compare central retinal thickness measurements at baseline and 3 weeks and 6 weeks postoperatively. Results All 48 patients (mean age 78.4 years; 60 eyes) had uneventful surgery. There were no cases of clinically significant CME. Subclinical CME detected by SD-OCT was confirmed in 2 eyes of different patients (3.3% of eyes), 1 eye 3 weeks postoperatively and another eye at 6 weeks. Subclinical CME resolved in both cases within 8 weeks. In both cases, the difference in central retinal thickness at baseline and 6 weeks postoperatively was statistically significant (P < .05). Conclusions The incidence of subclinical CME detectable on SD-OCT after routine phacoemulsification in patients using PGA eyedrops throughout the perioperative period was 3.3%. There were no cases of clinical CME. These findings might guide clinicians in their decision to use PGAs perioperatively.
