摘要:

An otherwise healthy 12-year-old boy was evaluated for an enlarged blind spot in his left eye. Neither optic nerve edema/neuritis nor a retrobulbar mass explained this finding. Consultation with a neuro-ophthalmologist over a period of 14 months resulted in a diagnosis of acute, idiopathic blind spot enlargement syndrome, a rare and poorly understood ocular condition. To the author’s knowledge, this is the youngest case ever reported.

摘要:

PurposeTo evaluate preoptometry and optometry school grade point averages and Optometry Admission Test (OAT) scores as predictors of performance on the National Board of Examiners in Optometry NBEO Part I (Basic Science) (NBEOPI) examination.MethodsSimple and multiple correlation coefficients were computed from data obtained from a sample of three consecutive classes of optometry students (1995–1997; n = 278) at Southern California College of Optometry.ResultsThe GPA after year two of optometry school was the highest correlation (r = 0.75) among all predictor variables; the average of all scores on the OAT was the highest correlation among preoptometry predictor variables (r = 0.46). Stepwise regression analysis indicated a combination of the optometry GPA, the OAT Academic Average, and the GPA in certain optometry curricular tracks resulted in an improved correlation (multiple r = 0.81). Predicted NBEOPI scores were computed from the regression equation and then analyzed by receiver operating characteristic (roc) and statistic of agreement (&kgr;) methods. From this analysis, we identified the predicted score that maximized identification of true and false NBEOPI failures (71% and 10%, respectively). Cross validation of this result on a separate class of optometry students resulted in a slightly lower correlation between actual and predicted NBEOPI scores (r = 0.77) but showed the criterion-predicted score to be somewhat lax.ConclusionsThe optometry school GPA after 2 years is a reasonably good predictor of performance on the full NBEOPI examination, but the prediction is enhanced by adding the Academic Average OAT score. However, predicting performance in certain subject areas of the NBEOPI examination, for example Psychology and Ocular/Visual Biology, was rather insubstantial. Nevertheless, predicting NBEOPI performance from the best combination of year two optometry GPAs and preoptometry variables is better than has been shown in previous studies predicting optometry GPA from the best combination of preoptometry variables.

摘要:

BackgroundThe Getman-Henderson-Marcus Visual Manipulation Test (VMT) is a commonly used test of visualization with an objective scoring procedure. However, its repeatability has not been studied.PurposeThe purpose of this investigation was to assess the repeatability of the VMT in children in the second through fourth grades.MethodThe VMT was administered to the children (n = 193; mean age, 8.72 years) from a middle class elementary school near Columbus, Ohio. One class from each grade (n = 56) was retested by the same optometrist within 1 month. Repeatability analysis included plotting the difference vs. the mean of the scores obtained at the initial test and retest.ResultsAll the children were able to complete the test. Means and SD’s were found to be 5.23 ± 1.98 for second graders, 5.76 ± 2.10 for third graders, and 6.95 ± 2.30 for fourth graders. The mean difference between test and retest scores was close to zero. The 95% limits of agreement were found to be −4.5 to 5.2.ConclusionNo consistent learning effect seemed to be present upon retest. However, analysis revealed poor repeatability for the VMT. Therefore, the VMT should not be used to monitor progress with therapy.
