Cataract progression in India.

AIMS: The study was undertaken to test the feasibility of using the LOCS III cataract grading scale in the field and to determine the rate of cataract progression over a 1 year period of time. METHODS: For 150 subjects between the ages of 33 and 55 who attended the refraction clinic at Aravind Eye Hospital in Madurai, India, lens abnormalities were graded at the slit lamp using the LOCS III scale. One year later, 99 of the subjects were re-evaluated by the same methodology to assess the amount of lens change. RESULTS: Interrater reliability was high. A change of 0.5 or more in lens colour, cortical, nuclear, or posterior subcapsular cataract was observed in at least one eye of 54% of the subjects. CONCLUSION: The LOCS III grading scale is a feasible method for measuring lens changes in the field with the slit lamp. Cataract progression in India is rapid enough to permit intervention studies to be performed with relatively small numbers of subjects over a short period of time (that is, 600 subjects for 2 years).

The influence on students' specialty selections of faculty evaluations and mini-board scores during third-year clerkships.

The authors investigated whether graduating students' specialty choices were influenced by favorable faculty evaluations and mini-Board scores during their third-year clerkships, and if so, whether the influences were gender-specific. Data were collected from a total of 53 students in two classes, 1988-89 and 1988-90. Univariate and multivariate tests were performed, and the results were analyzed between each class group and between genders in both groups. These results also were compared with information about the students gathered before they matriculated. In general, the results showed a gender-specific correlation: for each rotation where the women's faculty evaluations were significantly higher than the men's, the women subsequently outnumbered the men in choosing that rotation's specialty. Conversely, for each rotation where the men's mini-Board scores were significantly higher than the women's, the men outnumbered the women in choosing that rotation's specialty. The most notable difference was in pediatrics: 8% of the women had indicated an interest in that specialty on the prematriculation questionnaire, while almost one-third of the women in the classes of 1990 and 1991 chose pediatrics residencies. These findings suggest that the favorable scores and evaluations may be one of the influences for students' specialty choices, and that their influence may be gender-specific.
