To evaluate the influence of cataract surgery on the central choroidea and vitreomacular interaction using two different OCT devices.
We evaluated 33 eyes of 33 patients, 23 patients showing normal retinal architecture and 10 patients with diagnosis of age-related macular degeneration (AMD). All patients were scheduled for cataract surgery. The patients underwent spectral-domain (Spectralis-SD-OCT) and swept-source (SS-Topcon DRI) OCT measurements. 6x6mm (20°x20°) volume and 8.9mm line scans with SD-OCT using the enhanced depth imaging (EDI) mode for the visualization of the choroid. 6x6mm (512x64) and 12mm scans were performed using SS-OCT. Measurements were done before cataract surgery, one day, one week and one month thereafter.
We included 23 patients with normal fundus and mean age of 66±8.4 years and 10 patients with AMD and mean age of 76±11.5. Preoperative central choroidal volume (CCV) in patients with normal fundus was 0.21±0.06/0.20±0.06mm3 (SD/SS-OCT), 0.19±0.05/0.19±0.05mm3 one day after surgery, 0.19±0.05/0.19±0.05mm3 after one week and 0.20±0.06/0.21±0.07mm3 after one month, respectively (p>0.05). No significant changes were found regarding CCV after cataract surgery at each time point (p>0.05). AMD group showed a mean CCV of 0.16±0.05/0.16±0.07mm3 preoperative, 0.16±0.05/0.16±0.07mm3 one day after surgery, 0.16±0.05/0.15±0.05mm3 one week and 0.15±0.05/0.16±0.05mm3 after one months. The CCV was significant thinner in the patients with AMD (p=0.03), however, no significant different changes were observed after cataract surgery in this group and between the two devices (p>0.05). Preoperative, vitreomacular adhesion (VMA) was observed in 38%, vitreomacular traction (VMT) in 6%, macular vitreous detachment (MVD) in 13% and posterior vitreous detachment (PVD) in 41%. After one month VMA was seen in 33%, VMT in 4%, MVD in 22% and PVD in 41% with both SS and SD-OCT evaluations being identical.
Successful cataract surgery does not seem to have an influence on CCV. Spectralis and Topcon devices show comparable outcomes concerning evaluation of central choroidea and vitreomacular interaction.
