Surgical Success Rate of Scleral Buckling Surgery and Postoperative Incidence of Cystoid Macular Edema: 10 Years of Experience at a Single Academic Hospital

The purposes of this study were to report the surgical success rate of scleral buckling surgery (SB) for rhegmatogenous retinal detachment (RRD) in a single academic hospital, analyze the incidence of cystoid macular edema (CME) after SB using optical coherence tomography (OCT), and reveal the factors associated with the development of CME. This was a retrospective observational study of patients with RRD who underwent SB from 2010 to 2020 in a single academic hospital. The anatomical success was initially achieved in 267 of 288 eyes (92.7%), and finally achieved in 288 eyes (100%). After excluding 17 eyes that underwent vitrectomy for reoperations, a total of 271 eyes of 267 patients (173 men; age, 43.5 ± 16.9 years) were retrospectively analyzed to evaluate the incidence of postoperative CME. CME occurred in 6 of 271 eyes (2.2%) within 3 months after initial surgery. Pseudophakic and aphakic eyes appeared more likely to develop CME (chi-squared test: p = 0.0078). Five of the six cases with postoperative CME were able to be medically treated. Scleral buckling surgery showed a high success rate even in the era of small-gauge vitreous surgery, and the postoperative frequency of CME after SB was low (2.2%). Previous cataract surgery may be associated with the development of postoperative CME, which is mostly medically manageable

四国沖の黒潮の流量の評価

日本南岸での黒潮の絶対流量と熱流量を評価するために，四国の足摺岬から南南東に延びる観測線 ASUKAを設け．その測線上で集中した協同海洋観測を行った． 1993~1995年の 2年間の集中観測のうちの最初の 1年間の係留流速計の記録と．その間に繰り返し行った測線沿いのCTD/XBT観測のデータを組み合わせて．黒潮の絶対的な地衡流断面を求め，その面積積分から絶対流量を求めた．それによって，黒潮の流量と水位差の間に非常に高い相関があることが分かった．この関係を使って，人工衛星 TOPEX/POSEIDON海面高度計データから，黒潮の絶対流量の約 3年間にわたる時系列を得た．得られた流量の時系列には，はっきりとした季節変化は見られなかった．1. はじめに / 2. 観測 / 3. 観測結果 / 4. 黒潮の流量 / 5. おわり

Ferroelectric and mesomorphic properties of oxovanadium(IV) complexes with long alkoxy chains

The chiral and racemic oxovanadium(IV) salmmencomplexes, [VO(X)-(C16-salmmen)] (X = R(1),S(2), and rac(3); C16-salmmen = N,N’- monomethylenebis(5-hexadecyloxysalicylideneimine)) containing 5-substituted alkoxy chains on aromatic rings were synthesized, and their mesomorphic behaviorsand ferroelectric properties were also investigated. All complexes exhibited bothsmectic A and chiral smectic C mesophasesabove 360 K, andthey showed ferroelectric properties in the chiral smectic C mesophase
