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.
Idiopathic macular hole (IMH) refers to full thickness defects of retina in macular area with no clear reasons. The management of IMH includes vitrectomy combined with internal limiting membrane (ILM) peeling and pharmacological vitreolysis. But ILM peeling may damage the inner retina; novel techniques, such as inverted ILM flap technique and foveola non-peeling ILM surgery, autologous ILM transplantation had made the method of ILM peeling more diversified with less damage. Pharmacological vitreolysis targeting fibronectin and laminin is considered to work in a two-step mechanism, involving both vitreoretinal separation and vitreous liquefaction. Furthermore, IMH judgment and prognosis indicators like ellipsoid zone, macular hole index, hole formation factor, diameter hole index and tractional hole index based on spectral domain optical coherence tomography enriched the assessment of macular hole diameter, depth and shape. How to make full use of new interventions to reduce the incidence of macular hole and obtain a better visual acuity with closed holes is an important direction for future research.
ObjectiveTo investigate the factors correlated with the visual outcome of idiopathic macular holes (IMH) after vitreoretinal surgery. MethodsA total of 57 eyes of 57 patients with IMH were included. There were 43 females (43 eyes) and 14 male (14 eyes), mean age was (60.46±4.79) years. All the eyes underwent best corrected visual acuity (BCVA), slit-lamp microscope, three-mirror contact-lens and optical coherence tomography (OCT) examinations. BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution (logMAR) acuity. The minimum diameter and base diameter of macular holes and central retinal thickness (CRT) were detected by OCT. The average logMAR BCVA of 57 eyes was 0.98±0.41. The minimum diameter and base diameter of macular holes were (479.53±164.16) μm and (909.14±278.65) μm. All the patients underwent pars plana vitrectomy combined with phacoemulsification cataract extraction and intraocular lens implantation. The mean follow-up period was (173.44±147.46) months. The relationships between final BCVA and these parameters were examined by single and multiple regression analysis. The valuable influence factors were filtrated and formulated using multiple linear regression models. ResultsAt the final follow-up, the logMAR BCVA of 57 eyes was 0.44±0.31, the CRT was (158.79±86.96) μm. The final BCVA was positive related to minimum diameter of macular holes and preoperative BCVA (r=0.420, 0.448; P=0.001, 0.000), negative related to postoperative CRT (r=-0.371, P=0.004). There was no relationship between the final BCVA and base diameter of macular holes, age and follow-up (r=0.203, -0.015, 0.000; P=0.130, 0.913, 0.999). The incidence of preoperative BCVA for postoperative BCVA was bigger than preoperative minimum diameter of macular holes (P=0.008, 0.020). ConclusionThe preoperative minimum diameter of macular holes and BCVA are related to postoperative BCVA in IMH eyes.
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 therapeutic effect of vitrectomy combined with single-layer inverted internal limiting membrane (ILM) flap covering technique for rhegmatogenous retinal detachment (RRD) complicated with macular hole (MH).MethodsA retrospective case analysis. From January 2015 to August 2019, 29 eyes of 29 patients with RRD and MH diagnosed in the First People's Hospital Affiliated to Shanghai Jiaotong University were included in this study. There were 16 males (16 eyes) and 13 females (13 eyes). All the eyes were peripheral RRD and involving the macular area, while complicated with MH and proliferative vitreoretinopathy in stage less than C. All the eyes were examined by BCVA and OCT. The BCVA examination was performed using the Snellen visual acuity chart, which was converted into logMAR visual acuity. Before 2017, 18 eyes were treated with vitrectomy combined with ILM peeling (ILM peeling group); after 2017, 11 eyes were treated with vitrectomy combined with single-layer inverted ILM flap covering technique (ILM inverted group). The differences of age (t=0.360), onset time (t=1.235), number of holes except MH (t=0.060), RRD range (t=1.232), gas filled eyes (χ2=0.324) between the two groups were not statistically significant (P＞0.05). The average follow-up time after surgery was 4.5 months. The BCVA, retinal reattachment and MH closure at the last follow-up in the two groups were comparatively observed. U-shaped or V-shaped retina was defined as MH closure.ResultsAt the last follow-up, retinal reattachments were achieved in all the eyes. In ILM peeling group, 5 eyes (27.8%, 5/18) were completely closed in typeⅠ. In ILM inverted group, 9 eyes (81.8%, 9/11) were completely closed in typeⅠ. There was a statistically significant difference of closure rate in type Ⅰ closure between the two groups (χ2=5.968, P=0.015). The mean logMAR BCVA in ILM peeling group and ILM inverted group were 1.24±0.28 and 0.97±0.39, respectively. The difference of logMAR BCVA between the two groups was statistically significant (t=2.179, P=0.038).ConclusionVitrectomy combined with single-layer inverted ILM flap covering technique can increase the BCVA and MH closure rates in RRD patients with MH.
ObjectiveTo observe the changes of retinal thickness in idiopathic macular hole eyes after vitrectomy combined with internal limiting membrane peeling. MethodsThe study included 40 eyes in 40 consecutive patients with idiopathic full-thickness macular holes who underwent vitrectomy and internal limiting membrane peeling. There were 10 males (10 eyes) and 30 female (30 eyes), the average age was (63.60±6.26) years, the average disease duration was (6.00±3.53) months. All patients were examined by spectral-domain optical coherence tomography to measure the foveal retinal thickness, parafoveal retinal thickness and every quadrant in 1, 3, 6 months after surgery. ResultsCompared foveal retinal thickness after 1 month with 3 month, the difference was significant (F=4.527, P=0.013). But foveal retinal thickness were not significantly different in 3 months and 6 months after surgery (F=2.031, P=0.971). The difference of average parafoveal retinal thickness between 1 month, 3 months and 6 months after surgery was not significant (F=2.011, P=0.139). The retinal thickness of the operated eyes were not significantly different from the normal fellow eyes in 1 month after surgery (t=0.651, P=0.519). And the foveal retinal thickness of the operated eyes and the normal fellow eyes are significantly different in 3 months and 6 months after surgery (t=-2.563, -2.524; P=0.015, 0.016). The thickness of temporal were thicker than other quadrant in 1 month, 3months and 6 months after surgery (t=-3.701, -4.612, -4.125; P=0.014, 0.006, 0.009). ConclusionThere is a transient increase in the foveal retinal thickness after macular hole surgery.
ObjectiveTo evaluate the associated factors for predicting anatomical outcomes of idiopathic macular hole (IMH) after vitrectomy. MethodsThis is a retrospective study. A total of 165 eyes in 164 IMH patients underwent a successful vitrectomy and ILM peeling surgery were included in this study.The patients included 43 males and 121 females, with the mean age of (64.0±6.7) years. The corrected vision acuity of logarithm of the minimum angle of resolution (logMAR), indirect ophthalmoscope and spectral domain optical coherence tomography (SD-OCT) were measured for all patients. The mean logMAR corrected vision acuity was 1.0. The duration of disease was (8.7±14.9) months. The minimum diameter (MIN), base diameter (BASE) and height (H) were 521, 1010, 406 μm respectively. The macular hole index (MHI), tractional hole index (THI), diameter hole index (DHI) and macular hole closure index (MHCI) were 0.43, 0.82, 0.57, 0.92 respectively. Anatomical outcomes were divided into 3 levels. A: bridge-shaped healing; B: good healing; C: poor healing. The mean follow-up was (3.6±3.2) months. The multiple factors related with prognosis including age, sex, duration of disease, preoperative logMAR corrected vision acuity, MIN, BASE and H, MHI, THI, DHI, MHCI were analyzed. ResultsDuration of disease (r=0.141), preoperative logMAR corrected vision acuity (r=0.082), age (r=0.044), sex (r=0.109) was independent of anatomical prognosis (P > 0.05). MIN (r=0.397), BASE (r=0.276), H (r=-0.240), MHI (r=-0.363), THI (r=-0.432), DHI (r=0.272) was weak correlation to anatomical prognosis (P < 0.05). MHCI correlated significantly with anatomical outcomes (r=-0.543, P=0.000). The median MHCI of A, B and C were 1.07, 0.91, 0.56 respectively. There were significant difference of MHCI among the three levels (H=52.857, P < 0.05). ConclusionsMHCI has the best correlation with anatomical outcomes. It can be considered a key factor for predicting anatomical outcomes of IMH after vitrectomy.
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）
ObjectiveTo observe the healing morphology, macular microstructure and visual function of idiopathic macular hole (IMH) after pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) flap.MethodsRetrospective case study. From 2016 to 2018, 39 eyes of 39 patients with IMH diagnosed in Tianjin Eye Hospital were included in the study. Among them, there were 4 eyes in 4 males and 35 eyes in 35 females, with an average age of 64.56±7.2 years. BCVA, OCT, OCT angiography (OCTA) and MAIA microperimetry examination were performed in all patients. BCVA examination was performed with the international standard visual acuity chart, which was converted to logMAR visual acuity when recording. All patients underwent PPV combined with ILM flap covering and air tamponade. According to the characteristics of OCT images postoperatively, the eyes were divided into U-shaped closed group, V-shaped closed group, irregular closed group and flat closed group, with 26, 5, 7 and 1 eyes respectively. There was a significant difference in the minimum hole diameter (F=5.118, P=0.005) and macular hole classification (F=3.608, P=0.024). The shallow capillary layer (SCP) blood flow density in the U-shaped closure group was significantly higher than that in the V-shaped closure group, the irregular closure group and the flat closure group (t=2.079, 2.368; P=0.047, 0.025). At 1, 3, 6 months after the operation, the same equipment and methods were used for relevant examination. The blood flow density of BCVA, SCP, perimeter of foveal avascular zone (PERIM) and mean sensitivity (MS) were compared before and after operation. Independent sample t-test was used for quantitative data comparison between different groups, and χ2 test was used for counting data comparison.ResultsSix months after operation, the logMAR of the eyes in the U-shaped closure group was －0.75±0.29 higher than that before operation, and was better than that in the V-shaped closure group, the irregular closure group and the flat closure group (t=－2.974, －2.518; P=0.006, 0.018). The integrity of external limiting membrane (ELM) and ellipsoid in U-shaped closed group was significantly higher than that in V-shaped closed group, irregular closed group and flat closed group (χ2=15.229, 10.809; P=0.020, 0.013). The percentage of macular central fovea reflex mass in the U-shaped closed group was significantly lower than that in the V-shaped closed group, irregular closed group and flat closed group (χ2=20.107, P=0.000). PERIM in U-shaped closure group was smaller than that in V-shaped closure group, irregular closure group and flat closure group, and the difference was statistically significant (t=－3.391, －2.427; P=0.002, 0.022). The total MS of macular area 10 °in the U-shaped closure group was significantly higher than that in the other V-shaped closure group, irregular closure group and flat closure group (t=2.939, 2.811; P=0.001, 0.001).ConclusionAfter IMH operation, the U-shaped closure showed better BCVA and macular light sensitivity, the proportion of ELM and ellipsoid to restore structural integrity are higher, PERIM is smaller, and there are fewer macular fovea strong reflex masses.
