Purpose: To assess prospectively the features of the macular surface in silicone oil-filled eyes after surgery by analyzing whether silicone oil affects optical coherence tomography (OCT) measurements and their reproducibility and whether a statistical correlation exists between postoperative best-corrected visual acuity (BCVA) and foveal thickness measured by OCT. Methods: Twenty eyes of 20 patients underwent vitrectomy with silicone oil tamponade for retinal detachment. After vitrectomy, complete ophthalmic examination including determination of BCVA and OCT was performed to quantify the visual recovery and the foveal thickness. Results: Ophthalmoscopy revealed that the retina appeared to be reattached in all 20 eyes at 3 months after surgery. BCVA ranged from 0.4 logMAR to 1.7 logMAR, and foveal thickness ranged from 80 mu m to 500 mu m. Postoperative foveal thickness and BCVA had a strong correlation (r = 0.93; P = 0.003). Conclusion: The presence of silicone oil in the vitreous chamber does not change the reproducibility of OCT measurements of foveal thickness (coefficient of reproducibility, 1.48%). This study showed high statistical correlation between BCVA and foveal thickness. Therefore, postoperative BCVA is affected by postoperative foveal thickness, and visual improvement is limited in eyes with increased or decreased foveal thickness.

Abstract

Purpose: To assess prospectively the features of the macular surface in silicone oil-filled eyes after surgery by analyzing whether silicone oil affects optical coherence tomography (OCT) measurements and their reproducibility and whether a statistical correlation exists between postoperative best-corrected visual acuity (BCVA) and foveal thickness measured by OCT. Methods: Twenty eyes of 20 patients underwent vitrectomy with silicone oil tamponade for retinal detachment. After vitrectomy, complete ophthalmic examination including determination of BCVA and OCT was performed to quantify the visual recovery and the foveal thickness. Results: Ophthalmoscopy revealed that the retina appeared to be reattached in all 20 eyes at 3 months after surgery. BCVA ranged from 0.4 logMAR to 1.7 logMAR, and foveal thickness ranged from 80 mu m to 500 mu m. Postoperative foveal thickness and BCVA had a strong correlation (r = 0.93; P = 0.003). Conclusion: The presence of silicone oil in the vitreous chamber does not change the reproducibility of OCT measurements of foveal thickness (coefficient of reproducibility, 1.48%). This study showed high statistical correlation between BCVA and foveal thickness. Therefore, postoperative BCVA is affected by postoperative foveal thickness, and visual improvement is limited in eyes with increased or decreased foveal thickness.
