Diplopia from peribulbar ropivicaine.

PURPOSE: To report a previously undescribed side-effect of ropivicaine (Naropin) used in peribulbar anaesthesia. METHODS: We report nine cases identified prospectively with symptomatic diplopia, predominantly vertical, following Ropivicaine use for peribulbar anaesthesia in routine cataract surgery. These nine cases occurred in a 10-week period from a total of 77 patients given 7 mL peribulbar ropivicaine (10 mg/mL) with 750 units hyalase prior to cataract extraction by a single surgical team. RESULTS: None of the cases had preoperative ocular motility disturbances and none had superior rectus traction sutures. All diplopia resolved in less than 30 h. CONCLUSIONS: Ropivicaine may have a prolonged motor block resulting in diplopia of up to 30 h duration after peribulbar anaesthesia.

Photoscreening to detect potential amblyopia.

Photoscreening to detect amblyopiogenic conditions is particularly applicable for the child under three years of age because conventional testing is difficult. We have designed an eccentric photoscreener that is inexpensive, easily used and requires only one diagnostic photograph. Some 231 infants and children were refracted and photoscreened and results compared in a blind study. Compliance was good and all cases of strabismus, amblyopia, and amblyopiogenic conditions were diagnosed.

Random dot stereogram E in vision screening of children.

The random dot stereogram E (RDE) has been shown to be a simple and effective test for the detection of binocular abnormalities and defective visual acuity in children. We determined the validity of the RDE as a screening test for reduced visual acuity, amblyopia and strabismus in two separate populations of children. A nonselective group of 100 school children (aged 5 to 15 years) who presented consecutively to the ophthalmology department at Auckland Public Hospital were tested with the RDE. All cases of amblyopia and strabismus were detected by the RDE. Similar screening with the RDE test of 168 preschool children (aged three to four years) in the community resulted in an unacceptably high over-referral rate. The test was unreliable in the preschool age group because of difficulty in distinguishing between test failure and non-cooperation with the test. The low positive predictive value of the test in the younger age group suggests the test to be unsuitable for preschool vision screening.
