Conditions
- OCTA Changes With Local Anesthesia
Interventions
- Local Anesthesia (peribular injection of both lidocaine 2 % and hyaluronidase 150IU\ML)
- Local Anesthesia (peribulbar anesthesia injection of mepivacaine 2% and hyaluronidase 150IU\ML)
- Local Anesthesia (retrobulbar anesthesia injection of lidocaine 2 % and hyaluronidase 150IU\ML)
- local Anesthesia (retrobulbar anesthesia injection of mepivacaine 2% and hyaluronidase 150IU\ML)
Primary outcomes
- Macular superficial capillary plexus (SCP) and deep capillary plexus (DCP — ntervention & data collection :4-6 monthes
to detect degree of changes in vessel density at superficial and deep macular plexuses before and after injection of each group of anesthesia
