PURPOSE: To compare mini-mental state examination (MMSE) score between glaucoma group and normal control group and to evaluate the correlation between MMSE score and spectral domain-optical coherence tomography (SD-OCT) values in both groups. METHODS: This prospective study includes thirty glaucoma patients (eleven primary open angle glaucoma and nineteen normal tension glaucoma) and thirty normal controls. Retinal nerve fiber layer (RNFL) and Ganglion cell-inner plexiform layer (GC-IPL) thickness were measured with SD-OCT, and the average values of both eyes were used. The cognitive function was evaluated with MMSE by a single examiner. RESULTS: The mean MMSE scores of glaucoma group and normal group were 26.07 ± 2.95, and 27.00 ± 1.68 respectively (p = 0.137). MMSE score of less than 24 only showed in glaucoma group. MMSE score and RNFL thickness showed statistically no signifance in correlation (R² = 0.236; p = 0.070), however, MMSE score and GC-IPL showed statistically significant correlation (R² = 0.256; p = 0.048). CONCLUSIONS: Glaucoma patients tend to show low cognitive function even though the correlation between glaucoma patient and low cognitive function was not statistically significant. Therefore, the aspect of cognitive depression should be concerned, when facing glaucoma patients.

To investigate the population densities of potential malaria vectors, Anopheles species were collected by light traps in malaria endemic areas, Paju and Gimpo, Gyeonggi-do of Korea. Five Anopheles Hyrcanus sibling species (An. sinensis, An. pullus, An. lesteri, An. kleini, and An. belenrae) were identified by PCR. The predominant species, An. pullus was collected during the late spring and mid-summer, while higher population consists of An. sinensis were collected from late summer to early autumn. These 2 species accounted for 92.1% of all Anopheles mosquitoes collected, while the other 3 species accounted for 7.9%. Taking into account of these population densities, late seasonal prevalence, and long-term incubation period (9-13 months) of the Korean Plasmodium vivax strain, An. sinensis s.s is thought to play an important role in the transmission of vivax malaria in the study areas.
