AIM To investigate the effect of retrobulbar and subconjunctival anaesthesia on retrobulbar haemodynamics by colour Doppler imaging. METHOD 39 patients (mean age 71 (SD 9) years; 19 females, 20 males) undergoing planned cataract surgery were included in the prospective study. Colour Doppler imaging (Siemens Sonoline Sienna, Germany) was performed before, directly after either subconjunctival ...

purpose: to compare the efficacy and safety of two local anesthetic methods; retrobulbar anesthesia and parabulbar anesthesia using ptfe intravenous cannula without needle in extracapsular cataract surgery. method: a randomized prospective partially blind study was conducted on 66 eyes of 66 patients with senile cataract who were scheduled for ecce and pc iol surgery. after randomization, 35 pa...

The large majority of patients undergoing ophthalmic surgery are elderly and take systemic medications on a regular basis, including antiplatelet and anticoagulant treatments. It is current practice for many physicians to discontinue antithrombotic treatment prior to surgery to reduce bleeding complications that may lead to retrobulbar haemorrhage and, ultimately, to loss of vision. However, di...

Day-case cataract surgery and the need for local anaesthesia are likely to increase. Retrobulbar (and peribulbar) anaesthetic injection is a common technique in cataract surgery, but serious complications are persistently reported. Subconjunctival injection is an alternative that avoids these risks. This retrospective study compares two groups of patients that underwent extracapsular cataract s...

BACKGROUND Anecdotal evidence has previously suggested that retrobulbar local anaesthetic (LA) injection is accompanied by the rapid onset of ptosis. Here the validity of this potentially valuable sign is tested. METHODS 25 patients received a retrobulbar injection and the times for development of ptosis and akinesia in other extraocular muscle groups were recorded and compared. The effects o...

Acute retrobulbar haemorrhage (ARBH) is a rare ophthalmic emergency observed following blunt eye trauma. Multiple trauma and loss of consciousness can hide symptoms of ARBH. Rapid diagnosis and immediate lateral canthotomy and cantholysis must be performed to prevent permanent visual loss in patients. Medical treatment can be added to surgical therapy. Lateral canthotomy and cantholysis are sim...

Extracapsular cataract extraction with lens implant under local anaesthesia consisting of amethocaine drops followed by a simple subconjunctival injection in the upper part of the globe but without a retrobulbar injection was carried out in 175 eyes of 165 patients. The purpose of the study was to establish the feasibility of this type of anaesthesia in cataract surgery with the principal objec...

after sub-Tenon anesthesia In their recent article, 1 Subbiah et al. noted that a rigid sub-Tenon cannula caused complications such as a retrobulbar hemorrhage, albeit rarely. The authors concluded that a ‘‘soft cannula’’ could be an ideal alternative for sub-Tenon injection in high-risk patients. We reported the same thing in our Sandwell technique, in which the soft plastic sheath of a Venflo...
