The importance of injection rate in achieving a single intraocular gas bubble.
We investigated factors involved in achieving a single gas bubble following intravitreal gas injection during surgery for retinal detachment. A simple mathematical model of gas bubble dynamics within the eye was developed. The model indicates that the speed at which the bubble rises within the eye is proportional to the radius of the bubble. The flow rate required to maintain a single bubble increases as a power function of the bubble radius. In conclusion, the speed of injection is of paramount importance in the attainment of a single gas bubble.
