Buy Neuronox 50UI
Buy Neuronox 50UI : We performed a triple-masked, randomized control study to compare Botox and Neuronox in 48 eyes of 24 patients with BEB. All 24 patients randomly received Botox or Neuronox in the periorbital region in a masked, randomized split-face manner, keeping the injection sites and doses uniform. The toxin preparation, injection, and clinical evaluations were done by three independent observers. Objective outcome measures included improvement in the severity of spasm, grading of the functional visual status, changes in palpebral fissure height, lagophthalmos, superficial punctate keratitis and Schirmer’s test at 2 weeks, 6 weeks, and upon conclusion of the effect of the toxin. Subjective outcome measures included duration of the effect and a forced choice stating which half of the face was better. Evaluations were performed through clinical measurements, external digital photography, and high-definition videography. Buy Neuronox 50UI
The mean duration of relief from spasms was 3.78 months (standard deviation, 1.58 months; range, 1 to 6 months). The improvement in the objective parameters like severity of spasm and functional visual status was statistically significant at the 2-week and 6-week follow-up visits (p < 0.001). The changes in palpebral fissure height, lagophthalmos, and superficial punctate keratitis were equally observed in both groups. At 2 and 6 weeks, three of 24 (12.5%) and one of 24 (4%) patients, respectively, reported an unequal effect between the two sides of the face, but this difference was not statistically significant. At final follow-up (conclusion of the toxin effect), patients reported equal effect with no preference for either hemiface. No statistically significant differences were found in the comparative analysis between the Neuronox and Botox groups.
