Effect of pterygopalatine blockade on perioperative stress and inflammatory outcomes following paediatric cataract surgery.

Background: General anesthesia is required to perform pediatric cataract surgery. To reduce severity of surgical intervention and postoperative complications, regional techniques have been concomitantly used. The traditional regional ophthalmic techniques are retrobulbar, peribulbar and sub-Tenon blocks, which present some technical difficulties and associated complication risks.
