    ABSTRACT: We report a rare case of 49,XXXXY syndrome with autoimmune diabetes (requiring insulin therapy), bilateral cataracts and unilateral glaucoma. A 25-year-old man with mental retardation presented with multiple skeletal abnormalities, polyuria and polydipsia. He had high glucose concentrations, without ketonuria, and hypergonadotropic hypogonadism. Ophthalmic examination revealed a polar cataract in both eyes and increased intraocular pressure in the left eye. The anti-islet cell antibody test was positive, and anti-glutamic acid decarboxylase autoantibody levels were elevated. Karyotype analysis revealed 49,XXXXY. Intensive insulin therapy and testosterone replacements were started. The autoimmune nature of diabetes that we observed in our patient seems to be predisposed by hypogonadism. Cataract and glaucoma in this case seem to be the result of diabetes, and an association of these ocular manifestations with the syndrome 49,XXXXY seems unlikely.

    ABSTRACT: To assess the safety and efficacy of topical lidocaine, levobupivacaine, and ropivacaine in cataract surgery with phacoemulsification.METHODs: One hundred and five patients scheduled for cataract surgery with topical anaesthesia were randomly allocated into 3 groups of 35 patients each to receive eye drops of lidocaine 2%, levobupivacaine 0.75%, or ropivacaine 1% every 5 min starting 30 min before surgery. Patients graded their pain using a 0-10-point verbal pain score (VPS) at different stages of the procedure. The levels of patient and surgeon satisfaction, the duration of surgery, complications, and the need for supplemental anaesthesia were recorded. There was no significant difference in duration of surgery and demographic variables among the groups. At the intraoperative period, end of surgery, and postoperative first hour the mean VPS in the lidocaine group was significantly higher than the others (P<0.01), but no significant difference was found between the levobupivacaine and ropivacaine groups. At incision and 24 h after surgery, it was not significantly different among the groups. Surgeon and patient satisfaction scores were significantly better in the levobupivacaine and ropivacaine groups than in the lidocaine group (P<0.01). Topical anaesthesia with levobupivacaine and ropivacaine were safe, feasible and more effective than lidocaine in cataract surgery. Levobupivacaine and ropivacaine provided sufficient and long-lasting analgesia without the need of supplemental anaesthesia for each patient.

    ABSTRACT: To compare a bupivacaine and lidocaine mixture with levobupivacaine and ropivacaine in terms of safety, efficacy and blocking quality in peribulbar anaesthesia for phacoemulsification. A total of 105 patients scheduled for cataract surgery with peribulbar anaesthesia were randomly allocated into three groups of 35 patients each, to receive 5 ml of, respectively, a 1 : 1 mixture of bupivacaine 0.5% and lidocaine 2% (group 1), levobupivacaine 0.75% (group 2), or ropivacaine 1% (group 3). Ocular movement scores were evaluated at 2, 4, 6, 8 and 10 mins after injection. Intraoperative and postoperative analgesia were evaluated by verbal pain scores. Duration of surgery, need for supplementary anaesthesia, haemodynamic parameters and the incidence of perioperative complications were recorded. The ocular movement score in min 2 was significantly lower in group 1. There was no significant difference between groups 2 and 3. Ocular movement scores at mins 4 and 6 were significantly decreased in group 1 and 2 compared with group 3. There was no significant difference among the groups in ocular movement scores at mins 8 and 10. Verbal pain scores in postoperative hour 4 were highest in group 3, but scores for the intraoperative period and postoperative hours 1 and 2 were similar among the groups. Duration of surgery and haemodynamic parameters did not differ among the groups. All agents were considered to be convenient for clinical use in cataract surgery with peribulbar anaesthesia. Although the ocular movement scores in the ropivacaine group were higher than in the other groups at mins 4 and 6, this did not imply any clinical significance.
