Purpose

Retrobulbar hemorrhage is one of the most feared complications following the retrobulbar injection. Retrobulbar hemorrhage can result with optic nerve and retinal artery compression, and the ischemic process can result with permanent visual function loss. The Atkinson’s needle is commonly used for the retrobulbar injections, and has an oval tip which is considered safe for the injection. However, because the hemorrhage still can be observed following the injections, safer injection techniques are required. Therefore, in the current study, we aimed to describe a new injection technique which was performed by using a dermal filler cannula.

Methods

The injections were performed using 16 eyes of the 8 fresh-frozen cadaver heads and colored silicone gel. A 22-gauge needle was used as a guide, and the skin muscle septum complex was penetrated by the guide needle. Silicone gel injections were performed by using a 4 cm and 25-gauge cannula into the retrobulbar intra-conal space. After the injection, the exenteration of the orbit was performed, and, tissues were evaluated.

Results

According to the results, out of the 16 injections, 11 injections were performed into the retrobulbar intra-conal space. Additionally, artery, glob or optic nerve injury was not observed.

Conclusion

According to the results, using the dermal filler cannula can be a safe alternative for the retrobulbar injection.
