Purpose: The disinfection effectiveness of 5% anerdian Ⅲ, 0.016% gentamicin, and 0.5% tobramycin solutions in presurgical irrigation of conjunctival sac were compared.

Methods: A total of 295 cataract patients (302 eyes) who had undergone phacoemulsification aspiration combined with intraocular lens insertion (IOL) were recruited in this prospective study. Operative eyes were given 0.3% levofloxacin eye drops for 3 d and then were randomized into three treatment groups, anerdian (A), gentamicin (B) and tobramycin (C). The patients received conjunctival sac irrigation using the respective solutions at 10 min preoperatively. conjunctival sac sampling was performed before and after irrigation and the samples were used for subsequent bacterial culture and swab tests. The positive rate was used as the main parameter.

Results: Positive rates of bacterial culture before conjunctival sac irrigation: the positive rate was 17.31% (18 eyes) in group A, 13.86% (14 eyes) in group B and 17.3% (14 eyes) in group C. Post irrigation, the positive rates in the three groups decreased to 5.76% (6 eyes), 5.94% (6 eyes) and 7.22% (7 eyes), respectively. The positive rates among the three groups did not differ. However, the positive rate in group A significantly differed before and after the irrigation (P<0.05). No toxic or allergic reactions were found in the ocular surface of any patient after the irrigation. 

Conclusion: The disinfection effects of the three types of conjunctival sac irrigations did not differ.

Background: Few prevalence studies on intermittent exotropia (IXT) based on Chinese populations. Furthermore, longitudinal change in this pattern within a local setting has not been reported in the past. This study aims to determine the pro?le of children with IXT in China.

Methods: A total of 7,537 subjects from nine multi-layer primary and secondary schools participated in this investigation. The position of eyes was examined by using Hirschberg test and alternate cover test. The obtained results were classi?ed according to respective features and analyzed statistically.

Results: The prevalence of IXT among the participants was 7.98%, accounting for 73.04% of all types of strabismus. Junior high school students had a lower prevalence of IXT than elementary and senior high school counterparts. Logistic regression analysis showed that IXT was mainly found in male pupils at high grades in rural areas and in male secondary students at high grade in urban regions.

Conclusions: IXT was shown to be more prevalent than other types of strabismus in Chinese children. Furthermore, the distribution and characteristics of IXT greatly varied among participants.
