Resumo: | PURPOSE: To compare the influence of topical anesthesia (AT) with lidocaine 2% gel and peribulbar anesthesia (PBA) on the position of the upper eyelid after phacoemulsification. METHODS: This is a prospective randomized study, that included the pre op and post-op assessment of the upper eyelid position in 63 submitted to phacoemulsification, and divided into two groups: 33 eyes with topical anesthesia and 30 eyes submitted peribulbar anesthesia . The palpebral fissure margin reflex distance were analyzed by an independent observer with the digital imageJ program before and 30 days after surgery. The possible association of the lid height with the following variables was analyzed : age,time of surgery, previous lid fissure height, cataract hardness, eye and sex. RESULTS: Based on lid fissure height reduction of any magnitude no significant difference of eyelid position was found between the two groups (p = 0.59). There was significant difference however, based on fall ≥ 1 mm reduction the superior lid margin between the two groups (p = 0.032). The G1 it presented lower positioning of upper eyelid margin (45.5%) compared with G2 (20%). The relative risk of ptosis is 2,3 times higher with AT when compared to PBA ; 95% confidence interval 1,01-5,1. It was observed that there was no significant association at 5% between the lowest position of the MPS (decrease ≥ 1 mm) and clinical variables studied in the overall sample groups or in isolation. CONCLUSION: There is no significant difference in the positioning of MPS between both techniques, but the peribulbar showed lower induction in the positioning of MPS when the criterion of ≥ 1 mm drop at 30 days post operatively. |
