| description | Yuki Nakano, Koichiro Manabe, Rie Osaka, Yukari Takasago, Aoi Ono, Mamoru Kobayashi, Tomoyoshi Fujita, Chieko Shiragami, Kazuyuki Hirooka, Akitaka Tsujikawa Department of Ophthalmology, Kagawa University Faculty of Medicine, Miki, Japan Purpose: To evaluate the effects of vitreomacular and cataract surgery on retinal oximetry in vitreomacular disease.Patients and methods: Thirty-eight eyes with epiretinal membrane (ERM) and 15 with idiopathic macular hole (MH) underwent 25 gauge pars plana vitrectomy combined with cataract surgery and intraocular lens implantation. Retinal oximetry was performed using the Oxymap T1 before, 1 month, and 6 months after surgery. Oxymap T1 simultaneously captures monochrome images of the fundus at two different wavelengths of light. Built-in Oxymap Analyzer software measures the oxygen saturation and vessel diameter.Results: Mean arterial oxygen saturation significantly increased from 96.8%±6.2% to 100.2%± 5.8% at 1 month and to 99.6%±5.8% at 6 months after surgery (P<0.01). Mean venous oxygen saturation also significantly increased from 54.6%±7.5% to 61.2%±6.4% at 1 month and to 62.6%±5.9% at 6 months after surgery (P<0.01). Mean arteriovenous (A-V) difference decreased from 42.2%±6.6% to 39.0%±7.8% at 1 month and to 37.0%±6.9% at 6 months after surgery (P<0.01). The ERM and MH groups showed similar changes in retinal oxygen saturation. However, there were no significant changes in the caliber of major retinal vessels after surgery (from 125.2±15.2 µm to 124.0±15.4 µm in artery, from 168.7±14.6 µm to 169.8±14.6 µm in vein).Conclusion: Oxymap T1 was able to measure the increase in oxygen saturation in retinal arteries and veins, which led to a decrease in the A-V difference in oxygen saturation after vitrectomy combined with cataract surgery. Keywords: oxygen saturation, vitrectomy, vitreomacular disease, retinal vessels |
