Abstract
SO.09.10 OCT macular thickness after uneventful cataract surgery von Jagow B., Ohrloff C., Kohnen T.
Klinik für Augenheilkunde, Klinikum der Johann Wolfgang Goethe-Universität Frankfurt am Main Objective: Cystoid macular edema is the most frequent cause for late postoperative decrease in visual acuity. Using Stratus-OCT standardized macular scan in the postoperative period, subclinical changes in macular thickness can be detected. With that method the safety of todays cataract surgery will be evaluated and possible of surgical and anatomical parameters will be investigated.
Methods: 64 eyes without macular pathology were included into this prospective study. 32 consecutive patients underwent cataract surgery by phacoemulsification and IOL-Implantation in one eye. The other eye was examined as a control group. Stratus-OCT (Zeiss) -minimal fovea thickness and perifoveal thickness were measured preoperatively, on the postoperative day, 1 week and 6 weeks postoperatively. At each time the best corrected visual acuity (BCVA) was tested and slit-lamp examination was performed. Ocular axial length, anterior chamber depth and Phaco-Time were documented.
Results: Mean preoperative foveal thickness (FT) was 185,77±28µm in both eyes. At six weeks postoperatively, FT increased to 197±32µm in the operated eyes and was 186±36µm in the control group. There was no significant change in the mean FT of both groups at any examination. The macular thickening at the first postoperative day was no indicator for increased macular thickness later on. No correlation between macular thickening and the documented parameters could be found. A clinical cystoid macular edema was diagnosed in 2 eyes (6%). In those eyes macular thickening bigger than 2 SD was observed
Conclusions: After cataract surgery no general change in central macular thickness can be observed. No predictive parameters for a later development of cystoid macular edema in eyes without macular pathology could be found in this study. The early changes in macular thickness could not predict the macular status after 6 months.
