作者： Ru Liu Guo-Ping Kuang Di-Xian Luo Xiao-He Lu Department of Ophthalmology Zhujiang Hospital of Southern Medical University Department of Ophthalmology the First People's Hospital of Chenzhou Institute of Translational Medicine the First People's Hospital of Chenzhou

AIM: To investigate choroidal thickness in pregnant women and compare the measurements with those of normal nonpregnant women. METHODS: Using enhanced depth imaging optical coherence tomography (EDI-OCT), choroidal thickness was measured at the fovea and at 1 mm and 3 mm superior, inferior, temporal, and nasal to the fovea in both healthy pregnant women and nonpregnant women. Pearson correlation analysis was performed to evaluate the relationships between subfoveal choroidal thickness (SFCT) and the demographic and ocular parameters. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using fixed-effects model when Meta analyses were conducted. RESULTS: Comparison of choroidal thickness between the groups showed that it was significantly greater in healthy pregnant women's eyes than in normal nonpregnant women's eyes at all locations except at 3 mm superior and 3 mm temporal from the fovea (Pchoroidal thickness in healthy pregnant women is greater than that in normal nonpregnant women.

AIM： To evaluate central macular thickness（CMT） and mean choroidal thickness（MCT） in eyes with branch retinal vein occlusion（BRVO）, before and after ranibizumab treatment using spectral domain-optical coherence tomography（SD-OCT）.·METHODS： Forty-two patients with unilateral BRVO and macular edema were included in this study. There were 25 men and 17 women. Using SD-OCT, choroidal thickness was measured at 500 μm intervals up to 1500μm temporal and nasal to the fovea. MCT was calculated based on the average of the 7 locations. All the eyes with BRVO were treated with intravitreal ranibizumab（0.5 mg/0.05 m L）. Comparisons between the BRVO and fellow eyes were analyzed using Mann-Whitney U test. Preinjection and post-injection measurements were analyzed using Wilcoxon test and repeated measure analysis.· RESULTS： At baseline, there was a significant difference between the BRVO and fellow eyes in MCT[BRVO eyes 245（165-330） μm, fellow eyes 229（157-327） μm]and CMT [BRVO eyes 463（266-899） μm, fellow eyes 235（148-378） μm（P =0.041, 0.0001, respectively）]. Following treatment, CMT [295（141-558） μm] and MCT [229（157-329） μm] decreased significantly compared to the baseline measurements（P =0.001, 0.006, respectively）.Also BCVA（log MAR） improved significantly（P=0.0001） in the BRVO eyes following treatment. After treatment CMT[BRVO eyes 295（141-558） μm, fellow eyes 234（157-351） μm]and MCT [BRVO eyes 229（157-329） μm, fellow eyes 233（162-286） μm] values did not reveal any significant difference in BRVO eyes and fellow eyes（P=0.051, 0.824,respectively）.· CONCLUSION： In eyes with BRVO, CMT and MCT values are greater than the fellow eyes, and decrease significantly following ranibizumab injection.

AIM： To investigate the pattern of diurnal variations of choroidal thickness of macular region of healthy individuals. ~ METHODS： A prospective study of 32 healthy female subjects was conducted. Each subject underwent 1） a questionnaire on daily schedule, 2） the Pittsburgh Sleep Quality Index questionnaire （PSQI）, and 3） ocular examinations including an eye dominance test, fundus photography, and sequential optical coherence tomography （OCT） imaging, on two separate days at five fixed 3h time intervals. choroidal thickness was measured by two masked graders. RESULTS： A significant diurnal variation of choriodal thickness at fovea （P〈0.001）, at 500 μm nasal （P〈0.001）, temporal to fovea （P=0.01） or 1500 μm nasal to fovea （P= 0.001） was observed. The median choroidal thickness peaked at 11：00 at fovea （P=0.01）, at 500μm nasal （P = 0.009） and temporal （P=0.03） to fovea. The median amplitude of foveal choroidal thickness was 20.5 pm （13, 31） and 20.0 μm （12.5, 28.2） for the first and second series of measurements, respectively. The greater amplitude of foveal choroidal thickness was associated with thickner initial foveal choroidal thickness [ 0.05 （0.03, 0.08）, P= 0.01], dominant eye 10.51 （4.02, 14.60）, P=0.04] in the multivariate linear regression. CONCLUSION： Our data show a significant diurnal variation of the choroidal thickness at fovea, at 500 μm nasal and temporal to fovea and 1500 μm nasal to fovea. Thicker initial foveal choroidal thickness and being dominant eye may influence the amplitude of foveal choroidal thickness.

作者： Masahiro Ishida Takashi Wakakuri Yutaka Imamura Department of Ophthalmology Teikyo University School of Medicine University Hospital Mizonokuchi

AIM： To determine the relationship between the subfoveal choroidal thickness（CT） and intraocular pressure（IOP） following idiopathic epiretinal membrane（ERM） ***： Retrospective observational case series of patients who had undergone 23-gauge vitrectomy for an ERM. The measurements of CT and IOP were done at the baseline and 1 d, 1 wk, 1, 3, 6, and 12 mo after the ***： Forty-four eyes of 43 patients with a mean age of 69.8±9.5 y were studied. The CT was 200.8±86.3 μm at the baseline, 210.1±83.5 μm at 1 d, 213.2±85.4 μm at 1 wk, 203.1±84.0 μm at 1 mo, 197.5±85.5 μm at 3 mo, 197.7±84.0 μm at 6 mo, and 191.2±86.8 μm at 12 mo after surgery. The CT on day 1 and week 1 after the surgery was significantly thicker than that at the baseline CT（P=0.0023 and P〈0.0001）. The CT at 12 mo after surgery was significantly thinner than the baseline（P=0.0062）. The IOP on day 1 and week 1 were significantly lower than the baseline（P〈0.0001 and P=0.0042）. The IOP at 1, 3, 6, and 12 mo after surgery were significantly higher than the baseline IOP（P=0.0087, P=0.0023, P〈0.00051, and P〈0.0001）. The rates of changes in the CT between baseline and day 1 and week 1 were significantly and negatively correlated with the rates of change in the IOP（P〈0.0001 and P=0.046）. In the group with the IOP change rate of-30% or less at 1 d postoperatively, the change rate of CT was-21.1% to 31.2%（9.8%±12.4%） and in the group of-29% or more, it was-8.9% to 28.0%（2.6%±8.9%）. The change rate of CT in the group with the IOP change rate of-30% or less was significantly higher than the group of-29% or more（P=0.016）.CONCLUSION： CT increases soon after the ERM surgery which is probably due to the transient hypotony, showing that IOP may be a significant confounding factor for CT.
