Objective To compare the axial length (AL) measured by Lenstar and contact AScan in the patients with idiopathic macular hole and study the correlation between the difference of the two measurements and the foveal thickness measured by optical coherence tomography (OCT). Methods Twenty-seven eyes of 26 idiopathic macular hole patients (IMH group) and 27 eyes of 25 patients with mild cataract (control group) were enrolled in this study. Foveal thickness was measured with 3D OCT. The AL was measured by Lenstar and contact A-Scan, and the consistency of the two measurements was determined by Bland-Altman analysis. The correlation between the difference of the two measurements and foveal thickness was analyzed by Pearson correlation analysis. Results Mean foveal thickness of IMH and control eyes were (372.85±60.02) μm and (243.44±22.50) μm, respectively. The difference between the foveal thickness of the two groups was highly significant (t=-10.490,P<0.001). In the IMH group, the AL measured by Lenstar and contact A-Scan were (23.20±1.12) mm and (23.18±1.13) mm, respectively, the difference between the two measurements was not statistically significant (t=-0.549,P=0.588), whereas in the control group, the AL was (23.41±0.72) mm by Lenstar and (23.33±0.74) mm by contact A-Scan, the two measurements were significantly different (t=-4.832,P<0.001). However, no correlation was found by Pearson correlation analysis between the difference of the two measurements and the foveal thickness in either IMH or control group (r=0.181,-0.141;P>0.05). ConclusionsAlthough there is no difference of axial length measurements using Lenstar and contact A-Scan in IMH eyes, in clinical measurements the results of two instruments should be taken into comprehensive consideration.
Objective To investigate the clinical characteristics of retinal degeneration (RD) with retinal holes and the therapeutic effect of argon laser therapy. Methods The data of argon laser therapy in 210 RD patients (224 eyes) with retinal holes who underwent the treatment in our department were retrospectively analyzed, which was compared with the data of argon laser therapy in 173 RD patients (198 eyes) without retinal holes. Results In RD patients with retinal holes, 89.7% of the patients were less than 60 years old (53.3% males and 46.7% females). Grid-like degeneration was found in 65.6% of the patients in whom 87.5% had the range of degeneration less than 1 quardrant. There were oval-shaped holes in 60.7% of the patients and accompanied with limited rhegmatogenous retinal detachment (LRRD) in 23.7%. Compared with RD patients without retinal holes, the ratio of patients with the age ofge;35 years, cystic degeneration, retinal lengthways small plica, and subjective symptoms was higher in RD patients with retinal holes; while the therapeutic effect of argon laser therapy on patients with LRRD was obviously less than whom without retinal holes (Plt;0.01 ). Conclusions RD with retinal holes often occurs in youth, most of whom have grid-like degeneration with the range of le;1 qua drant. The major types of retinal holes are oval-shaped degeneration without retinal detachment. There was no sex difference in RD patients with retinal holes and most of the patients have no subjective symptoms. The therapeutic effect of prophylactic argon laser therapy on RD patients with retinal holes but no retinal detachment is satisfying. (Chin J Ocul Fundus Dis, 2006, 22: 39-41)
ObjectiveTo analyze the clinical characteristic, treatment and prognosis of traumatic macular holes resulted from ocular contusion. MethodsThe clinical data of 47 cases with traumatic macular hole was retrospectively reviewed. The general condition of the patients was summarized, optical coherence tomography and multifocal electroretinogram (mfERG) were used to evaluate anatomic and functional outcomes. The patients were divided into observation group and surgery group by the treatment they received, and the prognosis was evaluated. ResultsTraumatic macular hole occurs mainly in male. In the observation group, the mean diameter of macular hole was(490.0±86.9)μm. During the 12 month follow-up, the holes in 7 cases (33.3%) were closed spontaneously, Vision and diameters of 14 cases (57.1%) maintained stable for a long time, the vision of 1 case (3.3%) declined mildly and the diameter of 1 case (3.3%) enlarged slightly. Visual acuity was improved significantly at last follow-up (Z=-2.40, P < 0.05). The amplitudes of N1 wave of mfERG increased both in central fovea and macular area(t=13.30, 5.06;P < 0.05).These data suggests that the macular function was recovered well. In the surgery group, the mean diameter of macular hole was(643.3±125.0)μm and statistically larger than that of the observation group (t=-4.76, P < 0.05). At the last follow-up, visual acuity were not improved significantly (Z=-1.79, P > 0.05). The amplitudes of N1 wave in 6 cases (23.1%) improved merely and the difference was not statistically significant(t=1.98, P > 0.05).These data suggests that the macular function was recovered slightly only in a few patients. ConclusionsA part of the patients with smaller diameters of macular holes may close spontaneously, and they may get better visual acuity. Vitrectomy may help to close the macular holes in some severe cases, but the improvement of functional outcomes is not significant.
ObjectiveTo compare the clinical characteristics and analyze the factors affecting vision prognosis of idiopathic macular hole (IMH) or myopic macular hole (MMH). MethodsA cross-sectional study. From October 2012 to October 2020, 336 patients with 346 eyes of IMH and MMH who were diagnosed in Shanxi Provincial Eye Hospital with continuous follow-up data after surgery were included. There were 346 eyes (336 cases), including IMH with 247 cases (255 eyes) and MMH with 89 cases (91 eyes), which were divided into IMH group and MMH group. Best corrected visual acuity (BCVA) and optical coherence tomography were performed in all eyes. The BCVA examination used the standard logarithmic visual acuity chart, which was converted into logarithmic minimum angle of resolution (logMAR) visual acuity. The age of outset in IMH and MMH was 64.8±6.6 and 59.2±8.1 years, the logMAR BCVA was 1.11±0.50 and 1.80±0.78, respectively. There were significant differences in age (Wald=34.507) and logMAR BCVA (Z=-7.703) between two groups (P<0.05). All eyes were performed inner limiting membrane (ILM) peeling or partial inverted ILM covering hole operation. After the operation, the vitreous cavity was filled with air, C3F8 and silicone oil, including 73, 102, 83 eyes in IMH group and 9, 10, 72 eyes in MMH group, respectively. Follow-up time after surgery was more than 2 months. The optimal BCVA and macular hole closure of the two groups were observed. If the quantitative data conformed to the normal distribution, the generalized estimating equation was used, otherwise, the Mann-Whitney U test or Kruskal-wallis test was used, the χ2 test was used for the comparison of categorical variables. Generalized estimating equation logistic regression analyzed the influencing factors of optimal BCVA after surgery and visual acuity success. ResultsIn IMH and MMH, the optimal logMAR BCVA were 0.71±0.36, 1.10±0.51 respectively, and 147 (57.6%, 147/255) eyes, 63 (69.2%, 63/91) eyes achieved visual success respectively. There was a significant difference in the optimal logMAR BCVA (Z=-6.803, P<0.005), but no difference in visual success rate (χ2=3.772) between the two groups. The visual success rate of IMH at the same baseline BCVA level was higher than that of MMH, and the difference was statistically significant (χ2=14.500, P=0.001). Logistic regression analysis showed that the influencing factors predicting poor optimal visual acuity after surgery were: IMH, baseline BCVA [odds ratio (OR)=2.941, 95% confidence interval (CI) 1.341-6.447, P<0.05], MH diameter (OR=1.003, 95%CI 1.001-1.005, P<0.05), silicon oil filling (OR=3.481, 95%CI 1.594-7.605, P<0.05); MMH, baseline BCVA (OR=2.549, 95%CI 1.344-4.834, P<0.05), C3F8 filling (OR=18.131, 95%CI 1.505-218.365, P<0.05) and silicon oil filling (OR=7.796, 95%CI 0.997-60.944, P<0.05). The factors leading to a lower likelihood of achieving visual success: IMH, baseline BCVA (OR=213.329, 95%CI 46.123-986.694, P<0.05), MH diameter (OR=0.995, 95%CI 0.992-0.997, P<0.05), silicon oil filling (OR=0.326, 95%CI 0.115-0.926, P<0.05) and duration (OR=1.036, 95%CI 1.005-1.067, P<0.05); MMH, baseline BCVA (OR=13.316, 95%CI 2.513-70.565, P<0.05) and duration (OR=1.022, 95%CI 1.001-1.044, P<0.05). ConclusionsMMH was earlier than IMH in age of outset. Baseline vision significantly affected vision prognosis in IMH and MMH. Silicone oil should be avoided as much as possible under the premise of hole closure.
Objective To observe the hole closure rate of swept-source optical coherence tomography (SS-OCT)-guided facedown positioning for idiopathic macular hole (IMH) surgery. Methods A retrospective case series of 64 eyes of 64 patients affected with IMH. All the patients underwent a 25G pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and intraocular perfluoropropane (C3F8) tamponade. In 35 eyes of 35 patients, the facedown positioning was halted after detecting an hole closure through intraocular gas in the SS-OCT images at the early period after surgery (the SS-OCT group). In 29 eyes of 29 patients, the facedown positioning was halted atter detecting an hole closure in the SS-OCT images when the macular zone was uncovered by intraocular gas (the control group). The follow-up was ranged from 6 to 11 months, with the mean follow-up time was 8.4 months. The hole closure rate at 6 months after surgery were compared between two groups by two independent sample Wilcoxon rank sum test. The duration of the facedown positioning and complications were compared between two groups. Results The period of facedown position was (1.67±1.28) and (7.65±1.42) days in the SS-OCT group and control group, respectively. The difference of the period of facedown position between the two groups was significant (Z=−6.784, P<0.05). At 6 months after surgery, the hole closure was detected in 30 eyes (85.71%) in the SS-OCT group and in 27 eyes (93.10%) in the control group. There was no difference of hole closure rate between the two groups (χ2=0.889, P>0.05). There was no ocular serious side effect during the follow up, such as leakage of sclera incision, retinal hemorrhage, choroidal hemorrhage and endophthalmitis. In the control group, there were two patients with mild dizziness who underwent symptomatic treatment. There was no systemic side effect during the follow-up in the SS-OCT group. Conclusion Confirming with SS-OCT imaging early closure of macular hole of IMH patients with gas tamponade can serve as an important guide to significantly shorten the period of facedown positioning, while achieved a high hole closure rate.
ObjectiveTo investigate the surgical methods and efficacy of myocardial infarction combined with ventricular septal perforation.MethodsThe clinical data of 60 patients with myocardial infarction combined with ventricular septal perforation admitted to the Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, from 2009 to 2018 were retrospectively analyzed. There were 39 males and 21 females, aged 63.3±8.3 years.ResultsAmong the 60 patients, 43 (71.7%) patients were perforated in the apex, 11 (18.3%) in the posterior septum and 6 (10.0%) in the anterior septum. There were 24 (40.0%) patients of single coronary artery disease. Fourteen (23.3%) patients received intra-aortic balloon counterpulsation before surgery. The waiting time from ventricular septal perforation to surgery was 48.3 (3-217) d. All patients underwent ventricular septal perforation repair, among whom 53 (88.3%) patients received ventricular aneurysm closure or resection, and 49 (81.7%) patients received coronary artery bypass graft with an average of 2 distal anastomoses during the same period. Perioperative complications in the hospital included 8 (13.3%) deaths, 8 (13.3%) heart failure, 5 (8.3%) ventricular fibrillation, 3 (5.0%) pericardial tamponade, and 11 (18.3%) secondary thoracotomy and 11 (18.3%) residual shunt. Except for 8 patients who died in the hospital, the other 52 cured and discharged patients were followed up. The median follow-up time was 4.9 years. The 2-year and 5-year survival rate of the patients was 95.8%, and the 8-year survival rate was 89.0%. Major adverse cardiovascular events incidence was 19.2%, including 3 (5.8%) deaths, 5 (9.6%) heart failure, 2 (3.8%) myocardial infarction, and 4 (7.7%) cerebrovascular events.ConclusionFor patients with ventricular septal perforation after myocardial infarction, surgery is an effective treatment method. Although the perioperative mortality rate is high, satisfactory long-term results can be achieved by carefully choosing the operation timing and methods.
Objective To investigate a method of improving design of the skin flap pedicled with descending branch of lateral femoral circumflex artery, in order to increase the accuracy of preoperative Doppler location. Methods Firstly, the interspace between rectus femoris and vastus lateralis was regarded as line A, and the point of intersection between line A and the vertical line through the midpoint of the line between anterior superior iliac spine and lateral margin of patella was point A. And then the line between the midpoint of groin and point A was regarded as line B. Based on this , the perforating point of cutaneous branch could be located by Doppler along the line B. From November 2001 to October 2004, this method was used in 38 skin flaps of 37 cases, being all males and 16-48 years old. The area of the flap ranged from 7 cm×6 cm to 24 cm×16 cm. Results All the perforatingpoint of cutaneous branch were located outward the line A. The rate that the preoperative Doppler location was consistent with the utility point of formatting skin flap was 97.4%. All the cases were followed up postoperatively 1-20 months. Among the cases, 36 skin flaps of 35 cases was successful and only 2 skin flaps partially necrosed, which healed after changing dressings or skin graft.Out of 35 cases, the sensation restoration of the skin flap was S2-S3 in 6 cases owing to the anastomosis of lateral femoral cutaneous nerve and a skin nerve of the recipient site, while that of the other cases was S0-S1. Conclusion Preoperative Doppler location and improving design of lineB can be a useful instruction for the design of skin flap pedicled with descending branch of lateral femoral circumflex artery.
ObjectiveTo observe the changes in refractive status of eyes with idiopathic macular hole (IMH) after vitrectomy and phacoemulsification and IOL implantation (combined surgery).MethodsA retrospective clinical study. From January 2016 to June 2019, 51patients (56 eyes) of IMH who underwent combined surgery at the Tianjin Medical University Eye Hospital. were included in the study. Among them, there were 17 males and 34 females with the average age of 66.79±4.33 years. All the affected eyes underwent BCVA, retinoscopy and axial length (AL) measurement. The IOL power was calculated according to the SRK-T formula and the refractive power (predicted value) was predicted. The average BCVA of the affected eye was 0.20±0.13. The average anterior chamber depth was 2.89±0.28 mm. The average △corneal astigmatism was 0.73±0.43 D, the average AL was 22.92±0.70 mm, the average predicted refractive power was 0.10±0.66 D. All the affected eyes underwent standard transciliary flat part three-channel 25G combined surgery. Six months after the operation, the actual value (actual value) of the diopter after the operation was measured with the same equipment and method before the operation. Paired t test was used to compare the difference between the predicted value and the actual value.ResultsSix months after the operation, the actual value of the refractive power was -0.19±0.64 D. Compared with the pre-operative refractive power, the difference was not statistically significant (t=1.665, P=0.102). The difference between the actual value and the predicted value was -0.33±0.81 D.ConclusionsThe refractive status of the IMH eye undergoes myopia drift after combined surgery. The preoperative IOL power budget can be appropriately reserved for +0.3 D hyperopia.
Purpose To evaluate the surgical effect of idiopathic macular hole (IMH),with optical coherence tomography (OCT). Methods To measure the diameter of holes and hole halos,the thickness of hole in edge,the changes of hole pattern in 19 cases (19 eyes) with IMH using OCT. Results By quantitatively measuring,OCT showed that after surgery the mean hole diameter lessened from (570.95plusmn;264.59 )mu;m to (337.05plusmn;335.95)mu;m.The mean diameter of hole halo lessened from (1043.53plusmn;278.80)mu;m to (695.00plusmn;483.00)mu;m and the mean thickness of the hole edge thinned from (389.78plusmn;60.58)mu;m to (298.78plusmn;109.80)mu;m.In 17 eyes the holes become closed or reduced in size or the hole halo,and thinned in hole edge.The anatomic successful rate of the surgery is 89%. Conclusion OCT can objectively,accurately and effectively judge the anatomic effect of IMH surgery. (Chin J Ocul Fundus Dis,2000,16:71-138)
ObjectiveTo evaluate the clinical curative effect of posterior scleral reinforcement for macular retinoschisis in pathological myopic patients. MethodsA prospective study was conducted, in which 36 pathological myopia patients(36 eyes)with myopic foveoschisis were enrolled and divided into two groups according to the treatments: 24 patients (24 eyes) voluntarily underwent posterior scleral reinforcement (PSR, operation group) and 12 patients (12 eyes) didn't receive operation (control group). There are no statistical differences (P>0.05) in age, gender, length of axis oculi, spherical equivalent between the 2 groups. All patients were examined by best corrected visual acuity (BCVA), macular retinoschisis types, central foveal thickness (CFT), maximum foveal thickness (MxFT). Patients in operation group were scheduled to a follow-up 3rd, 6th, and 9th month after surgery respectively. Patients in control group all were followed up once every three months. A contrast observation was made on the changes of BCVA, CFT, MxFT, findings of the foveoschisis and the complications of the surgery between groups. ResultsCompared with the preoperation after 9 month follow-up: in the operation group, the BCVA was significantly increased postoperatively (Z=-3.43, P=0.01), the mean CFT was significantly decreased postoperatively (Z=-2.71, P=0.007), while the MxFT which was not significantly decreased postoperatively (Z=-0.67, P=0.503). In the control group, there was no significant change in BCVA (Z=-1.840, P>0.05), the CFT and the MxFT were signi? cant increased respectively (Z=-2.803, -2.04; P<0.05). In the operation group, there were 6 (25.0%) of the 24 eyes get complete resolution of the foveoschisis; 16 (66.7%) of them is not completely attached however the retinoschisis was significantly decreased; only 2 eyes developed to macular hole the other getting worse and the foveal thickness was increased. In the control group no one get complete resolution of the myopic foveoschisis, and 2 eyes developed to retinal detachment in 6 and 8 month respectively. There was no complications such as post-operative intra-ocular pressure increased, subretinal hemorrhage, macular epiretinal membrane, endophthalmitis, vortex vein circumfluence obstacle and anterior ocular ischemia syndrome occurred after surgery. ConclusionsPosterior scleral reinforcement surgery was found effective in improving the visual acuity, reducing the CFT. No obvious complications were found during and after the surgery.
