Purpose:
to evaluate cases of cystoid macular edema (CME) confirmed by OCT following cataract surgery in our department in a two year period ending on 30th November 2011.
Setting:
Department of Ophthalmology, Military Hospital, Budapest, Hungary
Methods:
OCT examinations have been performed in case of any postoperative visual deterioration following cataract surgery and cases of CME have been assessed (CME group). Comparisons have been made between patients in the CME group and all patients underwent cataract surgery during the period examined (control group, n=6126). Ophthalmic and general history (gender, age, hypertonia, diabetes mellitus, glaucoma, pseudoexpholiative syndrome (PEX), uveitis) as well as the role of intraoperative complications were questioned. Moreover, OCT examinations of 100 cataract patients (OCT100 group) with no other ophthalmic or general pathologies have been performed on 5 stated occasions (preoperatively, on the postoperative 1st, 7th day, 1st and 3rd month) focusing on the occurrence of CME.
Results:
23 cases (0.375%) of pseudophakic CME were detected, 13 male (1 binocular) and 9 female. In the CME group the proportion of males was 22% higher and the mean age was 4 years lower (69.2 ±13.7) compared to the control group. There were no alterations in terms of hypertonia, however, diabetes and glaucoma were both more frequent by 5% and 22%, respectively. 1 case of PEX (4.3%) and 2 cases of severe uveitis (8.7%) were explored in history, intraoperative complication happened in 2 cases (8.7%). In the control group these occurrences were 2.2%, 0.1% and 0.6%, respectively. The most frequent ophthalmic pathological finding was epiretinal membrane/vitreomacular traction (52%). We have no data about this regarding the control group. In the CME group mean BCVA was 0.33 preoperatively, 0.78 on the 1st postoperative day and 0.89 on the 7th. It deteriorated to 0.53 by CME and improved to 0.91 by the end of the follow-up period (39.3 ±24 weeks). CME appeared on postoperative week 7.6 ±5.2 and ceased on week 21.5±4.2. Central retinal thickness followed by OCT dropped from 519±136µm to 291±39µm in the control group. There was no case of CME in the OCT100 group.
Conclusions:
CME have been confirmed in 0.375% in our department following cataract surgery. Pathologies involving the macula and vitreoretinal border region, glaucoma, uveitis and diabetes are considered as risk factors. FINANCIAL DISCLOSURE?: No
