Phacoemulsification with IOL implantation was performed in all patients by same surgeon using same phaco machine (Oertli, Faros, Switzerland) and operation room set up under local anaesthesia (peribulbar
) with 2% lignocaine.
The surgery was performed under conventional peribulbar
The injuries were sustained during the administration of peribulbar
blocks, a technique whereby anesthesia is applied by needle injection around the sclera of the eye.
Other macroscopically observed events reported in previous studies, such as intraneural or intravascular injection and damage to the peribulbar
tissue, were not evidenced in the present study (GROSS et al., 2000; PERRY et al., 2015).
injection of xylocaine (2ml) was given through the inferotemporal quadrant.
Hoffmann, "Cultured peribulbar
dermal sheath cells can induce hair follicle development and contribute to the dermal sheath and dermal papilla," Journal of Investigative Dermatology, vol.
The surgery was done under peribulbar
anaesthesia (3 :1 of bupivacaine 0.5% and lidocaine 2%), in the superior quadrant, using the corneal traction suture.
Because of the potential intrasurgical risks and the duration of this procedure, the scleral fixation was performed under peribulbar
or general anaesthesia.
(10) Despite all of these advantages, injection anesthesia methods such as peribulbar
anesthesia, sub-Tenon's block, and especially retrobulbar anesthesia can also lead to several complications.
All operations were performed by the same surgeon under peribulbar
block is used to obtain anaesthesia and akinesia of the eye by injecting a local anaesthetic around the musclecone.
Nevertheless, this hypothesis might not adequately explain the pathogenesis of PCA, because dermal papilla-derived and peribulbar
dermal sheath cells transplanted into the skin also show the ability to regenerate hair follicles .
