Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

Arnold-Chirai malformation type II is congenital disorder which consists of downward displacement into upper cervical spinal canal of parts of the cerebellum, 4th ventricle, and medulla oblongata. We experienced two cases of Arnold-Chiari malformation with lumbar meningomyelocele, hydrocephalus. We confirmed the cases by brain C-T and report with brieft review of the lilterature.

PURPOSE: This study was conducted to measure macular ganglion cell-inner plexiform layer (mGC-IPL) thickness in patients with a history of unilateral single attack of acute primary angle closure (APAC) and to compare it with that of unaffected fellow eyes 8 weeks after resolution using spectrum domain optical coherence tomography (SD-OCT). METHODS: Medical records of 24 patients with history of first episode of unilateral APAC were reviewed retrospectively. Eight weeks after APAC, mGC-IPL thickness and peripapillary retinal nerve fiber layer thickness were measured with SD-OCT and analyzed in eyes affected by APAC (group 1) and fellow eyes (group 2). RESULTS: There were no significant differences between the groups with regard to best corrected visual acuity, spherical equivalent, central corneal thickness, or axial length (p > 0.05). There were no significant differences in mGC-IPL thickness in the superotemporal, superior, or superonasal sectors (p > 0.05). However, average, inferonasal, inferior, and inferotemporal sectors of group 1 were significantly thinner than those of group 2 (p = 0.002, 0.002, 0.001, 0.001, respectively). In addition, average mGC-IPL difference between affected eyes and fellow eyes showed a statistically significant correlation with attack duration (correlation coefficient = 0.249, p = 0.019). CONCLUSIONS: Normalization of elevated intraocular pressure as soon as possible after APAC onset is recommended in order to reduce mGC-IPL loss, and measurements of mGC-IPL thickness can be helpful for follow-up of APAC patients.
