Objective To determine the correlation between central macular thickness (CMT) and the visual function in patients iwht macular edema (ME). Methods The clinical data of 42 eyes of 40 patients with ME which were examined by optical coherence tomography (OCT) and microperimetry (MP-1) were retrospectively analyzed. In 40 patients (42 eyes), diabetic ME (DME) was in 27 eyes，branch retinal vein occlusion was in 11eyes, and central retinal vein occlusion was in 4 eyes. All of the eyes had undergone OCT，MP-1 and best-corrected visual acuity (BCVA) test. Central macular thickness (CMT) was measured by fast macular scans using OCT. Retinal sensitivity (MS) and fixation patterns were evaluated by Mp-1. The position was chosen :2 disc diameters (DD) temporal to the disc and one third of a DD inferior to the centre of the disc. Results The correlation between CMT and BCVA is not significant (r＝－0.429，P=0.069) as well as the correlation between CMT and MS (r＝－0.433，P=0.058). The difference of CMT between the unstable and stable group was significant (F=3.262, P=0.039）. The difference of CMT between the central fixation group and preferred retinal locus (PRL) group was significant (F=3.173, P=0.044). Conclusions BCVA and MS have no significant correlation with CMT. When CMT increases, the fixation stability decreases, fixation location.changes, and PRL occurs.
ObjectiveTo investigate the efficacy of stellate ganglion block (SGB) on postoperative palpebral edema in patients undergoing intracranial aneurysm surgery. MethodsSixty patients who were scheduled to undergo intracranial aneurysm surgery between September 2012 and Novermber 2014 were recruited, and were assigned into 2 groups randomly with 30 in each:SGB group and control group. Patients in SGB group were administered SGB by injecting 0.3% ropivacaine on the operative side under the ultrasound guidance after surgery completed, while patients in the control group received injection of saline on the operative side under the ultrasound guidance. Incidence of postoperative palpebral edema at hour 24, 48, and 72 after surgery were measured. Numerical rating scale (NRS) was used to detect the severity of uncomfortable symptoms for palpebral swelling during rest state. The severity of palpebral edema was evaluated with continuous rating scale (0-5, 0 indicated normal palpebral, and higher score indicated more serious palpebral edema). Complications related with SGB were recorded. ResultsThe overall incidence of palpebral edema at hour 24 after surgery in SGB group was lower than that in the control group (P<0.05). There was no statistically significant difference in the overall incidence of palpebral edema at hour 48 and 72 after surgery between the two groups (P>0.05). The palpebral edema rating scores of the SGB group at hour 24 after surgery were lower than those of the control group (P<0.01).The incidence of palpebral edema which was scored 3 or more at hour 24 and 48 after surgery in SGB group was lower than that in the control group (P<0.05). No statistically significant difference was found in the incidence of palpebral edema which was scored 3 or more at hour 72 after surgery between the two groups (P>0.05). No complication related with SGB was found. ConclusionSGB can safely reduce the incidence of postoperative palpebral edema in patients undergoing intracranial aneurysm surgery, and reduce the severity of palpebral edema.
Objective To investigate the application of quality control circle (QCC) activities in improving weight management ability of patients with renal edema. Methods A QCC activity group was founded, and " improving weight management ability of edema patients with kidney disease” was selected as the theme. Then the status of weight management ability in 51 patients with renal edema who were admitted to the Department of Nephrology from April 1st to 30th 2015 was investigated, the reasons of the low weight management ability were analyzed, and then appropriate countermeasures were carried out. After this activity, the status of weight management ability in 54 patients with renal edema who were admitted to the Department of Nephrology from October 1st to 31th 2015 was investigated, to assess the effect and consolidate the results of activities. Result After the QCC activities, the scores of weight management ability increased from 23.84±6.34 to 28.43±4.08 with statistical significance (P<0.05), and the qualified rate of weight management ability increased from 25.5% to 44.4% with statistical significance (P<0.05). Conclusion QCC activities can improve the weight management ability and the qualified rate of weight management ability of patients with renal edema, at the same time, it can improve the overall quality of nurses.
Objective To evaluate the clinical efficacy and safety of 577 nm subthreshold micropulse laser on diabetic macular edema (DME). Methods Retrospective case series study. A total of 30 patients (35 eyes) with center−involving DME were enrolled in this study. All the patients received the examinations of best corrected visual acuity (BCVA), fundus colorized photography, fluorescein fundus angiography (FFA) and optical coherence tomography (OCT). BCVA was measured by Early Treatment Diabetic Retinopathy Study charts. The average retinal thickness (ART), total macular volume (TMV) and the retinal thickness (RT) and macular volume (MV) of 9 ETDRS domains were measured by the Japanese Topcon 3D-OCT 2000 instrument. The mean BCVA was 62.4±10.5 letters. The mean ART was 327.3±41.2 μm. The mean TMV was 9.24±1.17 mm3. All patients were treated with 577 nm subthreshold micropulse laser treatment. Subthreshold micropulse laser were performed in the micropulse mode, using a 200 μm spot diameter, a 0.2 s duration with 5% duty cycle and its treatment energy was 6−7 times of threshold energy. Three months after treatment, re-treatment was performed on patients with incomplete absorption of macular edema. The treatment was the same as before. The BCVA, ART, TMV and the RT and MV of each ETDRS domain were compared and analyzed before and after treatment. The possible complications of micropulse laser treatment were also observed and the safety was evaluated. Results The difference of BCVA were statistically significant in month 3 and month 6 (t=−5.58, −7.24; P＜0.05), but not in month 1 (t=−1.82, P＞0.05). The average CRT (t=4.11, 4.17, 5.96), CMV (t=3.92, 4.05, 5.80) significantly decreased in 1, 3 and 6 months after treatment, the difference was statistically significant (P＜0.05). At sixth months, the average retinal thickness (t=3.53, 5.07, 5.02, 4.87, 4.94, 3.48, 4.03, 3.17, 3.73) and retinal volume (t=3.54, 5.16, 4.99, 4.91, 5.05, 3.47, 4.08, 3.10, 3.70) of the 9 ETDRS subdomains significantly decreased, and the difference was statistically significant (P＜0.05). There was no visible laser spots, changes in the outer retina and complications of neovascularization and subretinal fibrosis in the fundus of all patients. Conclusion577 nm subthreshold micropulse laser can reduce the CMT, CMV and improve the BCVA of DME patients with high security.
