Objective To evaluate and compare the prognosis of idiopathic macular holes (IMH) and traumatic macular holes (TMH) treated by pars plana vitrectomy (PPV).Methods The clinical data of 72 IMH eyes and 55 TMH eyes, which were treated by PPV between November 2001 and December 2007, were retrospectively reviewed. The visual outcomes and macular anatomic closure were evaluated, and their relationships with prognostic factors including the size of macular hole (MH), preoperative visual acuity (VA) and duration of disease were analyzed.Results The closure rate of IMH (100.0%) was significant higher than that of TMH (85.5%) (P=0.001). The postoperative VA of IMH and TMH were (0.25plusmn;0.02) and (0.21plusmn;0.21) respectively,both significantly increased compare to their preoperative VA (t=-6.841,-4.093; P=0.000). VAincreased IMH and TMH eyes had same VA （chi;2=3.651，P=0.07）. PrePPV VAge;0.1 IMH eyes had better outcomes than PrePPV VA＜0.1 IMH eyes （chi;2=12.04, P=0.001）, while PrePPV VA had no effects on TMH outcomes （chi;2=0.371，P=0.486）. IMH eyes with small holes had better outcomes （t=2.476，P=0.016）, and TMH eyes with small holes had better closure （t=-4.042, P＜0.001）. The duration of disease had no significant influence on TMH visual （chi;2=0.704, P=0.401） and anatomic （chi;2=0.166, P=0.684） outcomes. Conclusions PPV is an effective treatment for MH. The closure rate of IMH is higher than that of TMH. The diameter of MH and preoperative VA are major factors for IMH outcomes, and the duration of disease and preoperative VA have no effects on postoperative VA in TMH.
ObjectiveTo observe the clinical effect of vitrectomy with internal limiting membrane peeling and air tamponade in the treatment of idiopathic macular hole (IMH).MethodsA prospective, non-randomized controlled case cohort study. Twenty eyes of 20 patients with IMH in Ophthamology Department of The Second Hospital of Jilin University from September 2016 to January 2017 were included in this study. There were 4 males (4 eyes) and 16 females (16 eyes), with the mean age of 60.60±9.50 years and the mean disease course of 9.55±15.5 months. The stage of macular hole ranged from Ⅱ to Ⅳ. All patients underwent BCVA, intraocular pressure, spectral-domain OCT (SD-OCT) and multifocal ERG examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The minimum diameter (MIN), bottom diameter (BD), height (H), the defective diameter of ellipsoid zone, the defective diameter of external limiting membrane (ELM) of the macular hole were measured by SD-OCT (German Heidelberg). Then the macular hole index (MHI=H/BD), hole traction index (THI=MD/BD) and hole diameter index (DHI=H/MD) were calculated. The response density in P1 wave was detected by mf-ERG. The logMAR BCVA was 1.18±0.54. There were 5 eyes with less than 400 μm MIN, 13 eyes with 400-700 μm MIN and 2 eyes with over than 700 μm MIN. All the patients were underwent vitrectomy with internal limiting membrane peeling and air tamponade. According to the SD-OCT image features after surgery, IMH closure was divided into type Ⅰ closed, type Ⅱ closed and unclosed. The follow-up was equal or greater than 3 months. The closure rate of IMH, BCVA and the changes of microstructure parameters of macular area were observed. Spearman correlation analysis was used to analyze the correlation between BCVA and the wave response density in P1 before surgery and the efficacy after IMH surgery.ResultsClosure rate of IMH: 18 eyes (90.0%) were completely closed (all type Ⅰ closed). The closure rate of macular hole with the MIN less than 400 μm was 100.0% (5/5), 400-700 μm was 92.3% (12/13), and over than 700 μm was 50% (1/2). BCVA: the mean logMAR BCVA at 1 week, 1 month, 3 months after surgery were 0.83±0.54, 0.65±0.41, 0.48±0.34, and there was statistically significant difference between preoperative and postoperative BCVA (t=3.382, 4.459, 5.250; P=0.003, 0.007, 0.004). The outcomes of SD-OCT at 3 months after surgery: 18 eyes (90.0%) with intact ELM. The defective diameter of ellipsoid zone was 260.34±272.08 μm, there was statistically significant difference between before and after surgery (t=13.545, P=0.002). The outcomes of mf-ERG: the P1 wave response density of the ring 1 and ring 2 after surgery were increased compared with before surgery (t=-16.748, -6.151; P＜0.01,＜0.01). The results of Spearman correlation analysis: there was a positive correlation between postoperative BCVA and preoperative MIN, the defective diameter of ellipsoid zone and ELM, and postoperative the defective diameter of ellipsoid zone (r=0.56, 0.59, 0.68, 0.52; P=0.010, 0.006, 0.001, 0.019). The postoperative BCVA was negatively correlated with the P1 wave response density of ring 1 and ring 2 of mf-ERG (r=－0.34, －0.16; P=0.006, 0.020). The IMH closure had a significant negative correlation with MIN and the defective diameter of ELM (r=－0.449, －0.449; P=0.047, 0.047). MHI and THI were positively correlated with the closure of the hole (r=0.474, 0.546; P=0.035, 0.013). Intraocular pressure increased in 2 eyes during the follow-up period, and returned to normal within 1 week after the administration of antihypertensive drugs. There were no complications during or after the operation.ConclusionsVitrectomy with internal limiting membrane peeling and air tamponade in the treatment of IMH is safe and effective. The MIN, MHI THI are significantly correlated with the curative effect after IMH surgery, which could be used as the index to predict and evaluate the curative effect. The response density of ring 1 and ring 2 in P1 wave of mf-ERG is signifi-cantly improved compared with before surgery, and which is negatively correlated with BCVA.
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.
Purpose To explore the role of scanning laser tomography in the assessment of macular hole surgery. Methods Fifteen eyes of 14 patients with macular holes underwent scanning of their affected macular area using the Heidelberg retina tomograph (HRT). The significance of topographic changes postoperatively were determined in eleven eyes which received vitrectomy surgery. The scan field was set at 15°of the retina and the depth was set to 1.5 mm or 2.0 mm. All the measurements were taken for 3 times and the average value of the 3 measurements was used. Results The average hole area was (0.499±0.34) mm 2 and the maximal depth of the hole was (0.284±0.11) mm. Topographic difference analysis of the eleven eyes showed a significant reduction in the height of the retina after vitrectomy. The maximal depth of the hole was (0.063±0.04) mm postoperatively. Conclusion Scanning laser tomography provides an objective evaluation of the anatomic outcome of the macular hole surgery. (Chin J Ocul Fundus Dis, 2002, 18: 125-127)
Objective To evaluate the safety and efficacy of brilliant blue G (BBG) assisted internal limiting membrane (ILM) peeling on pathological myopic macular holes with retinal detachment.Methods This is a prospective and noncontrolled study. Twenty-seven high myopia patients （27 eyes） with macular holes and retinal detachment were enrolled. Routine examination was performed, including the best corrected visual acuity （BCVA）, intraocular pressure, slit lamp microscope with +90 D pre-set lens, A- or B-ultrasound,optical coherence tomography (OCT) and visual field. All patients received vitrectomy with BBG-assisted ILM peeling and C3F8 gas tamponade. The 5 followup visits were at the first day, the seventh day, the first month, the third month and the sixth month after surgery. The BCVA, intraocular pressure, visual field, macular hole and retinal reattachment were comparatively analyzed.Results The ILM of all patients were peeled completely by BBG staining. There were no major complications such as corneal edema, anterior chamber reaction, elevated intraocular pressure, visual field defects. At the first month after surgery, macular hole closed and retina reattached in 26 eyes （96.3%）, the macular hole did not close and retina redetached in one eye （25.9%）. At the sixth month after surgery, BCVA of 25 eyes （92.6%） increased, two eyes （7.4%） didnprime;t change, the difference was statistically significant （t＝6.08，Plt;0.05）.Conclusions BBG can fully stain ILM without any side effects. Vitrectomy with BBG-assisted ILM peeling is a safe and effective treatment for pathological myopic macular holes with retinal detachment.
OBJECTIVE:The study was undertaken to evaluate the clinical effects of an improved posterior seleral reinforcement procedure for retinal detachment(RD)with macular hole in high myopic patients. METHODS:Twenty high myopic eyes with RD and macular hole were treated in our hospital from March 1993 to November 1995 with posterior scleral reinforcement surgery and were retrospectiv- ely analysed. RESULTS:The average length of ocular axis was 28.22 mm on admission and 26.87 mm on discharge in 14 comparable eyes. The retinas were reattached in 17 eyes with corrected vision of 0. 02~0.2. The surgery was failed in 3 eyes and the PVR got worse. CONCLUSION :The improved pro- cedure can efficiently treat high myopic patients with RD and macular hole without severe PVR,and might be better for preserving the survival central vision than choroiretinal adhesive methods. （Chin J Ocul Fundus Dis,1996,12: 214-216）
The reattachment rate, macular hole (MH) closure rate, visual acuity improvement and re-detachment rate of MH retinal detachment (MHRD) of high myopia are not satisfactory owing to long axis oculi, posterior scleral staphyloma and macular atrophy. At present, minimally invasive vitrectomy surgery combined with the internal limiting membrane flap technique has become popular in the treatment of MHRD, as it can promote MH closure, and significantly improve the outcome of MHRD. However if this method can improve the postoperative visual function is still controversial. The advantage of this technique is that the loosened internal limiting membrane is applied to cover the MH surface to form a scaffold structure similar to the basement membrane. It can stimulate Müller cell gliosis more effectively, and promote tissue filling in the MH which results in MH closure. It can also promote retinal reattachment and reduce the likelihood of retinal re-detachment. This technique is expected to be a standard surgical method for the treatment of MHRD of high myopia in the future. The inserted internal limiting membrane flap technique is relatively easy to perform, induces stable flaps by simple procedures, and can be an essential complement procedure of the inverted internal limiting membrane flap technique. In order to reduce the recurrence rate in the future, it is necessary to further define the indications of different surgical methods and the predictive effects of MH healing mode on the success rate and visual function recovery.
Objective To compare the predicted efficiency of macular hole closure index (MHCI) calculated by 2 different methods for postoperative anatomical outcomes after idiopathic macular hole (MH) surgery. Methods This is a prospective exploratory clinical study. A total of 63 patients (63 eyes) with idiopathic MH, who received vitrectomy, inner limiting membrane peeling and gas tamponade, were enrolled in this study. All the patients received optical coherence tomography (OCT) examination at each visit to measure the MHCI using the formula MHCI=（M+N）/BASE, M and N is the distance from outer limiting membrane break points to the beginning points of detached photoreceptor from retinal pigment epithelium of both side of the hole, respectively. BASE is the length of MH base. MHCI1 was measured by built-in caliper of OCT software, MHCI2 was measured by ImageJ software. The minimum macular diameter (MHD) was measured by built-in caliper of OCT software. Based on the OCT images, the anatomical outcomes were classified grade A (bridge-like shape closure), grade B (complete closure) and grade C (poor closure). Grade A and B are considered as good closure, grade C as poor closure. Patients were followed up at 3, 6 and 12 months after surgery. The closure grades at last visit were the final outcome. The relationship between MHCI1, MHCI2 and closure grades was analyzed. And the predicted efficiency of MHD, MHCI1 and MHCI2 for anatomical outcomes after the surgery was studied. Results The mean MHCI1 was 0.68±0.21 (0.30-1.35), MHCI2 was 0.95±0.26 (0.41-1.55), and MHD was (476.24±210.18) μm (127-956 μm). MHCI1 and MHCI2 were both negative correlated with the closure grades (r=−0.665, −0.691; P＜0.001). The receiver operating characteristic (ROC) curve analysis of MHCI1, MHCI2 and MHD for the prediction of good or poor closure showed that area under the curve (AUC) was 0.928, 0.957 and 0.916 respectively, and 0.505, 0.67 and 559 μm were set as the lower cut-off value. The sensitivity was 96.2%, 92.3% and 90.9% respectively, and specificity was 81.8%, 72.7% and 76.9% respectively. Accordingly, the ROC curve analysis for the prediction of grade A or B closure showed that AUC was 0.840, 0.847 and 0.653 respectively, and 0.705, 0.965 and 364 μm were set as the upper cut-off value. The sensitivity was 80.0%, 82.9%, 63.4% respectively and specificity was 75.0%, 85.7%, 65.9%. Conclusion MHCI1 and MHCI2, measured by built-in caliper of OCT software or ImageJ software, both have good predictive efficiency for the anatomical outcomes of MH surgery.
ObjectiveTo observe the different changes of macular microstructure in patients with large idiopathic macular hole (IMH) treated with vitrectomy combined with internal limiting membrane (ILM) transplantation or not. MethodsForty eyes in 40 consecutive patients with giant IMH (≥500 μm) were included in the study. Twenty eyes received vitrectomy with ILM transplantation (ILM transplantation group) and others with ILM peel off (ILM removal group). During the operation, a proper size of the ILM was removed and filled in the bottom of the macular hole. The age, duration of disease and the ocular laterality of the two groups of patients were not statistically significant (P>0.05). Minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA) and frequency domain optical coherence tomography (SD-OCT) scan were examined. There was no statistically significant difference in logMAR BCVA, average defect diameter of photoreceptor ellipsoid (IS/OS) and average defect diameter of external limiting membrane (ELM) between two groups (t=0.128, 1.452, 1.321; P>0.05). The logMAR BCVA and SD-OCT were examined on 1, 3, 6, 12 months postoperatively. ResultsOn 1 month after the surgery, there was no statistically significant difference in logMAR BCVA, average defect diameter of IS/OS and average defect diameter of ELM between two groups (t=1.226, 1.435, 1.018; P>0.05). On 3, 6, 12 months after the surgery, compared with ILM removal group, the logMAR BCVA (t=2.059, 2.871, 2.415) increased and the average defect diameter of IS/OS (t=2.070, 2.110, 2.121) and ELM (t=2.034, 3.647, 3.556) significantly reduced in ILM transplantation group (P<0.05). On 1 month after the surgery, there was statistically significant difference in CRT between two groups (t=2.113, P<0.05). On 3, 6, 12 months after the surgery, there was no statistically significant difference in CRT between two groups (t=0.428, 0.847, 0.849; P>0.05). ConclusionCompared with vitrectomy combined with ILM peeling surgery, the diameter of IS/OS and ELM defect were significantly decreased after vitrectomy combined with ILM transplantation in the patients with large IMH.
ObjectiveTo observe the efficacy of vitrectomy combined with internal limiting membrane (ILM) peeling and scleral shortening for myopic foveoschisis (MF).MethodsProspective and non-randomized concurrent control study. A total of 35 MF patients (35 eyes) were enrolled in this study. The patients were divided into 2 groups according to surgery, including group A (18 eyes) and group B (17 eyes), all received vitrectomy combined with ILM peeling, but group A also received scleral shortening. The best corrective visual acuity (BCVA) examination using the Snellen vision chart was converted to the minimum resolution logarithm (logMAR). Ocular axis length (AL) was measured by Zeiss IOL-Master or A-scan ultrasound (Quantel Medical, France). The maximal value of retinal foveoschisis (MxFT) was measured by frequency-domain optical coherence tomography (Heidelberg, Germany). Multifocal electroretinogram (mfERG) responses were obtained with the RETIscan system (Roland Consult, Gemany).There was no statistically significant difference between the two groups (P＞0.05) in age (t=0.460), AL (t=1.520), diopter (t=0.020), logMAR BCVA (t=−2.280), MxFT (Z=−4.179) and b-wave ERG amplitude (Z=−0.198). The changes of BCVA, AL, MxFT and b wave amplitude were followed-up for 3-12 months.ResultsAt the last follow-up, the height of MF was decreased in 18 eyes of group A, and MF was completely disappeared in 4 eyes. The logMAR BCVA (t=7.272, 5.951), MxFT (Z=−3.724, −3.622) and b- wave ERG amplitude (Z=−3.223, −3.243) in both groups A and B were statistically improved (P=0.000, 0.000, 0.000, 0.000, 0.001, 0.001) compared to pre-operational results. There was significant difference of logMAR BCVA (t=−2.280) and MxFT (Z=−4.179) between the two groups (P=0.029, 0.000). But there was no significant difference in the amplitude of b-wave（Z=−0.198, P=0.843). The AL in group A was shortened after surgery, the difference was statistically significant (t=10.017, P=0.000). During the follow-up, there was no ocular hemorrhage, endophthalmitis and other complications.ConclusionPPV combined with ILM peeling and scleral shortening can shorten AL significantly for MF patients, and gain relative normal anatomical structure of the fovea, thus improve the vision.
