PERIPAPILLARY MICROVASCULAR ALTERATIONS AFTER SILICONE OIL TAMPONADE ASSESSED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

Abstract:

Silicone oil tamponade is widely used in the surgical treatment of complex retinal disorders; however, its possible influence on the microcirculation of the optic nerve remains insufficiently investigated. This exploratory longitudinal study evaluated changes in peripapillary microcirculation after silicone oil removal in patients who underwent vitreoretinal surgery with prolonged silicone oil tamponade. Twenty eyes of nineteen patients were followed after silicone oil removal and divided into two groups according to tamponade duration of one to six months and six to twelve months. Peripapillary microvascular parameters were assessed repeatedly during a twelve-month follow-up period. Both peripapillary vessel density and blood flow index demonstrated gradual improvement after silicone oil removal in both groups. Eyes with a shorter duration of silicone oil tamponade showed a more favorable pattern of microvascular recovery throughout follow-up. These findings suggest that prolonged silicone oil tamponade may be associated with slower restoration of peripapillary microcirculation after surgery.
