A new approach to treating retinal detachment with macular hole

Macular Buckling for Myopic Traction Maculopathy: A Comprehensive Systematic Review and Meta-Analysis

PURPOSE

Myopic traction maculopathy (MTM) is a major cause of visual impairment and blindness, particularly in Asian populations. With the global burden of myopia on the rise, understanding effective treatment options is crucial. This systematic review and meta-analysis evaluate the efficacy of macular buckling in the management of MTM.

DESIGN

A systematic review and meta-analysis.

METHODS

A systematic review and meta-analysis were conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Cochrane Library, and EMBASE databases were searched for relevant studies up to July 2024. Inclusion criteria encompassed studies reporting outcomes of macular buckling for MTM. Primary outcomes included changes in best-corrected visual acuity and axial length, retinal reattachment rate, and macular hole closure rate. Random-effect models were used for statistical analysis, with heterogeneity assessed using the I² statistic. The pooled results were reported as mean difference or proportion with corresponding 95% confidence intervals (CIs) for each outcome.

RESULTS

Thirteen studies (482 eyes) met the inclusion criteria. Significant improvements in best-corrected visual acuity were observed across all follow-up periods, with the most substantial improvement in long-term outcomes (mean difference: 0.38 logarithm of the minimum angle of resolution; 95% CI: 0.28-0.47). Axial length showed consistent reductions, with a mean long-term reduction of 2.88 mm (95% CI: 2.54-3.21). The pooled long-term retinal reattachment rate was 94% (95% CI: 86%-97%), while the long-term full thickness macular hole closure rate was 72% (95% CI: 55%-85%). Heterogeneity varied across outcomes and follow-up periods, ranging from low to high.

CONCLUSIONS

Macular buckling demonstrates promising outcomes for MTM, including improved visual acuity, reduced axial length, high retinal reattachment rates, and favorable macular hole closure rates. These findings support the efficacy of macular buckling as a treatment option for MTM. However, further standardized, long-term studies are needed to confirm these results and explore potential combination therapies.

Effectiveness of vitrectomy with inverted internal limiting membrane flap in the treatment of macular hole retinal detachment in high myopia

PURPOSE

This study evaluates the effectiveness of the inverted internal limiting membrane (ILM) flap technique during vitrectomy for treating macular hole-induced retinal detachment (MHRD) in high myopia patients, a challenging complication for vitreoretinal surgeons due to its treatment complexity.

METHODS

We conducted a prospective study analyzing 92 eyes diagnosed with MHRD, all undergoing vitrectomy using the inverted ILM flap technique between February 2022 and September 2024. Successful surgery was defined as achieving retinal reattachment, macular hole closure, and improvement in visual acuity by the 12-month postoperative follow-up. Microstructural recovery was assessed using spectral domain optical coherence tomography. Logistic regression analysis was performed to identify prognostic factors of surgical outcome.

RESULTS

Of the 92 eyes, 94.6% achieved retinal reattachment, and 92.4% experienced macular hole closure. Visual acuity significantly improved in 91.3% of cases, with a mean improvement of 0.95 logarithm of the minimum angle of resolution. Recovery rates for the external limiting membrane, the ellipsoid zone, and the cone outer segment tip were 76.1%, 66.3%, and 66.3%, respectively. Larger retinal detachments and macular holes were important predictors of lower surgical success (p < 0.001; p = 0.015, respectively). There was a significant correlation between vision improvement and the recovery of structural integrity and foveal microstructures.

CONCLUSIONS

The ILM coverage technique represents a breakthrough in the treatment of MHRD, promoting both anatomical and functional recovery. This approach enhances the management of this complex condition, ultimately improving the quality of life for affected individuals.

Comparison of the inverted internal limiting membrane flap technique without versus with an autologous blood clot for treating macular hole-associated retinal detachment

BACKGROUND

To investigate the anatomical and functional outcomes of macular hole-associated retinal detachment (MHRD) after vitrectomy using the inverted internal limiting membrane (ILM) flap technique with autologous blood clot (ABC).

METHODS

This retrospective observational study included 80 eyes with MHRD that underwent vitrectomy with ILM flap without (46 eyes) or with ABC (34 eyes). Fundus photography and optical coherence tomography were evaluated. The pre- and postoperative best-corrected visual acuities (BCVAs) and BCVA improvement were compared between the two groups.

RESULTS

The MH closure rates after initial surgery were similar in the ILM flap group and ILM flap with ABC group [40 (87%) vs. 29 (85%) eyes, respectively]. The proportion of eyes with hyperreflective bridging tissue (HBT) was lower in the ILM flap group than ILM flap with ABC group [13 (32%) vs. 16 (55%) eyes, P = 0.060]. The postoperative improvement in BCVA was significantly better in the ILM flap group (P = 0.027). Multiple linear regression analysis revealed that preoperative BCVA was positively associated with postoperative improvement in BCVA (β = 0.638, P = 0.000), while the ILM flap with ABC technique was negatively associated with postoperative improvement in BCVA (β =  - 0.299, P = 0.039, adjusted r2 = 0.415).

CONCLUSIONS

The inverted ILM flap technique alone resulted in better foveal configurations and visual outcomes than the ILM flap technique combined with ABC in patients with MHRD.

Historical and practical aspects of macular buckle surgery in the treatment of myopic tractional maculopathy: case series and literature review

BACKGROUND

Uncorrected myopia is a leading cause of blindness globally, with a rising prevalence in recent decades. Pathological myopia, often seen in individuals with increased axial length (AXL), can result in severe structural changes in the posterior pole, including myopic tractional maculopathy (MTM). MTM arises from tractional forces at the vitreoretinal interface, leading to progressive macular retinoschisis, macular holes, and retinal detachment (RD). This study aims to outline preoperative evaluation and surgical indication criteria for MTM, based on the MTM staging system, and to share our Brazilian experience with three cases of macular buckle (MB) surgery, all with over a year of follow-up.

METHODS

We conducted a retrospective analysis of three cases of MTM-associated RD treated with MB surgery, with or without pars plana vitrectomy. Preoperative evaluations included optical coherence tomography (OCT) and ultrasonography (USG) to assess the extent of macular involvement and retinal detachment. Surgical indications were determined based on the MTM staging system. The MB was assembled using customizable and accessible materials. Surgical procedures varied according to the specific needs of each case. An informed consent form regarding the surgical procedure was appropriately obtained for each case. The study was conducted with the proper approval of the institution's ethics committee.

RESULTS

All three cases demonstrated successful retinal attachment during the mean follow-up of eighteen months. In the first case, combined phacoemulsification, vitrectomy, and MB were performed for MTM with macular hole and RD. The second case required MB and vitrectomy after two failed RD surgeries. In the third case, a macular detachment with an internal lamellar hole was treated with MB alone. These cases highlight the efficacy of MB surgery in managing MTM in highly myopic eyes.

CONCLUSIONS

MB surgery is an effective treatment option for MTM-associated RD in highly myopic eyes, providing long-term retinal attachment. Our experience demonstrates that with proper preoperative evaluation and surgical planning, MB can be successfully implemented using accessible materials, offering a viable solution in resource-limited settings. Further studies with larger sample sizes are warranted to validate these findings and refine surgical techniques.

Epiretinal implant of human amniotic membrane to treat highly myopic macular hole retinal detachments: A novel surgical technique

PURPOSE

To describe a new surgical technique involving the use of a human amniotic membrane (hAM) epiretinal patch to treat a primary macular hole retinal detachment (MHRD) in a highly myopic patient.

METHODS

A 60 years old highly myopic man was referred to our clinic with a diagnosis of MHRD in his right eye. The patient was pseudophakic, with a visual acuity of counting fingers at the baseline evaluation. Pars plana vitrectomy was performed, a small retinotomy was created at the inner margin of the staphyloma, and membrane blue dual was used to obtain an adequate peeling of the inner limiting membrane. Then, a 1.5 mm diameter circular hAM patch was obtained and positioned over the macular hole with the chorion layer settled over the retina. After a complete fluid-air exchange, 20% sulfur hexafluoride gas was used as endotamponade, and the patient was asked to remain face down for three days.

RESULTS

Four weeks after surgery, optical coherence tomography (OCT) scan showed the hAM patch, visualized as a distinct hyperreflective layer well integrated with the retina. Nine months after surgery, the macular hole was closed, the retina reattached, the hAM patch was adherent to the retina, and the patient presented a best-corrected visual acuity improved to 0.7 logMar. No postoperative adverse events were registered during the follow-up.

CONCLUSIONS

Epiretinal hAM implant could represent a novel surgical technique, feasible and easier compared to other current techniques used to treat MHRD in highly myopic patients.

Management of Retinal Detachment With a Coexistent Macular Hole: Submacular Placement of Retinal Autograft Through a Macular Hole

PURPOSE

In this article, a submacular autologous neurosensory retinal transplantation technique is presented in patients with large macular hole (MH) accompanying retinal detachment.

METHODS

In the surgical procedure, 23-G pars plana vitrectomy and peripheral vitrectomy were performed. An autologous neurosensory retinal patch, which should be larger than the diameter of the MH, was released from a suitable quadrant. The retinal patch was grasped using a 23 gauge microforceps and then passed through the MH and placed under the macula. Liquid perfluorocarbon (PFCL) was injected, and the retina was reattached. A subfoveal autologous neurosensory retinal patch was repositioned in the center of the MH with gentle manipulation under fluid perfluorocarbon, if necessary. Laser retinopexy was applied to peripheral tears under PFCL Subsequently, a 5,000-cSt silicone oil-PFCL exchange was also performed.

RESULTS

Four eyes of four patients were operated on using the technique described earlier. Silicone oil was removed from two patients, and the macular holes were closed in all patients at the last follow-up.

CONCLUSION

This technique has been beneficial in refractory MHs and can improve the visual potential in eyes with MHs.

Closure rates and patterns after light silicone oil tamponade for persistent full-thickness macular holes

PURPOSE

To report outcomes of re-vitrectomy using light silicone oil (SO) tamponade for persistent macular holes (MHs).

METHODS

We reviewed cases of patients with full-thickness MHs that underwent pars plana vitrectomy (PPV) with air/gas and were re-vitrectomized using light SO tamponade after primary non-closure (persistent MHs). Outcome measures included anatomic closure rates and patterns confirmed by optical coherence tomography (OCT) and changes in best-corrected visual acuity (BCVA).

RESULTS

A total of 42 eyes of 41 patients with unsuccessful primary PPV with air/gas were included. After re-vitrectomy with light SO (1000-centistoke), 29 (69%) eyes demonstrated type 1 closure without neurosensory defects in OCT scans, whereas 9 eyes (21%) showed type 2 closure with persisting neurosensory defects. Available data (n = 21) showed a significant mean improvement of BCVA from 0.99 logMAR (SD 0.25, range 0.7-1.3) preoperatively to 0.74 logMAR (SD 0.42, range 0.2-1.5) postoperatively (p = 0.035).

CONCLUSION

The treatment of persistent MHs with PPV and light SO tamponade resulted in high closure rates.

Inverted internal limiting membrane flap technique for retinal detachment due to macular holes in high myopia with axial length ≥ 30 mm

To compare the efficacy of internal limiting membrane (ILM) flap covering to that of ILM flap insertion for the treatment of macular hole retinal detachment (MHRD) in highly myopic eyes with axial length (AL) ≥ 30 mm. We retrospectively analysed the medical records of 48 MHRD patients with high myopia (AL ≥ 30 mm). According to different surgical methods, the patients were divided into a covering group (23 eyes) and an insertion group (25 eyes). The rate of retinal reattachment and MH closure were compared between the two groups, and the related factors affecting the initial anatomical results were analysed. After primary vitrectomy and single silicone oil removal, there were 18 eyes (78.3%) in the covering group, and 20 eyes (80.0%) in the insertion group had retinal reattachment (P = 1.000). Moreover, 16 eyes (69.6%) in the covering group and 17 eyes (68.0%) in the insertion group had their MHs sealed (P = 0.907). The best-corrected visual acuity (BCVA) at 12 months and the improvement in BCVA postoperatively in the two groups were not statistically significant (P = 0.543, 0.955). Logistic regression analysis showed that elongated AL (OR = 1.844, 95% CI 1.037–3.280, P = 0.037) and higher choroidal atrophy (OR = 2.986, 95% CI 1.011–8.821, P = 0.048) were risk factors affecting initial anatomical success. For extremely high-myopia MHRD with AL ≥ 30 mm, ILM flap covering and insertion can both effectively seal the MH and promote retinal reattachment, but the visual function improvement may still be limited. The longer the AL and the higher the choroidal atrophy, the greater is the risk of initial anatomical failure.

A Comparison of Face-Down Positioning and Adjustable Positioning After Pars Plana Vitrectomy for Macular Hole Retinal Detachment in High Myopia

Purpose

To compare the anatomical and functional outcomes of macular hole retinal detachment (MHRD) in high myopia after pars plana vitrectomy (PPV) with face-down positioning and adjustable positioning.

Methods

Fifty-three eyes from 53 patients with MHRD were analyzed in this study. All patients received PPV with silicon oil for tamponade and then subdivided into 2 groups: 28 were included in a face-down positioning group and 25 were included in the adjustable positioning group. Patients were followed up for at least 6 months. The main outcome was the rate of anatomical macular hole (MH) closure and retinal reattachment. Secondary outcome measures were the best-corrected visual acuity and postoperative complications.

Results

There was no significant difference in the rate of MH closure (53.6 vs. 72.0%, p = 0.167) and retinal reattachment (100 vs. 96%, p = 0.472) between the face-down group and adjustable group. Compared with the mean preoperative best-corrected visual acuity (BCVA), the mean postoperative BCVA at the 6-month follow-up improved significantly in both groups (p = 0, both). But there was no significant difference in the mean postoperative BCVA (p = 0.102) and mean BCVA improvement (p = 0.554) at 6 months after surgery between the two groups. There was no significant difference in the high intraocular pressure (IOP) after surgery between the two groups (53.6 vs. 44%, p = 0.487). There were no other complications that occurred during the follow-up.

Conclusion

Adjustable positioning after PPV with silicon oil tamponade for MHRD repair is effective and safe. Face-down positioning does not seem to be necessary for all patients with MHRD.

Macular hole closure at seven years after surgery

Purpose

To report a case of macular hole (MH) closure at seven years after internal limiting membrane (ILM) peeling.

Observations

A 66-year-old woman developed a MH in her left eye. Pars plana vitrectomy with ILM peeling and SF6 gas injection followed by face-down position for a week slightly improved the visual acuity from 20/400 to 20/200 but did not close the MH. During subsequent three years of follow-up without any treatment, the MH did not close. Seven years after the surgery, she visited us for cataract surgery in her right eye, and the optical coherence tomography (OCT) examination coincidentally found closure of the MH in her left eye. The visual acuity of her left eye remained 20/200 despite the MH closure.

Conclusions and Importance

ILM peeling might indirectly contribute to the closure of MH at seven years after the surgery although the mechanism is unclear. Sharing the serial OCT images until the MH closure would help us explore the mechanisms of ILM peeling to close MH and develop rational surgery technique manipulating ILM for MH.

Recurrent macular hole retinal detachment in a patient with pathologic myopia treated by additional intravitreal silicone oil injection: A case report

RATIONALE

Treatment of macular hole retinal detachment (MHRD) in patients with pathologic myopia may require multiple surgeries due to the risk of surgical failures or recurrences. Intravitreal silicone oil injection before an additional surgery may be another option for recurrent MHRD in aphakic eyes, but this procedure is rarely performed.

PATIENT CONCERNS

A 69-year-old man visited the hospital with a chief complaint of metamorphopsia in his right eye for 5 days. The right eye had undergone a cataract extraction 5 years prior and an Nd:YAG laser capsulotomy 1 year prior. The axial length was 36.18 mm; the fundus examination and optical coherence tomography (OCT) revealed inferior retinal detachment with a macular hole involving the posterior pole. Pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, endolaser photocoagulation, and silicone oil tamponade were performed. Five months after the surgery, the retina was detached, and a macular hole was observed.

DIAGNOSIS

Recurrent MHRD in a patient with pathologic myopia.

INTERVENTION

PPV with ILM peeling, endolaser photocoagulation, and silicone oil tamponade at the initial visit and additional intravitreal silicone oil injection (0.5 ml) at follow-up visits.

OUTCOMES

The retina was well-attached until 5 months after the additional intravitreal silicone oil injection.

LESSONS

Additional intravitreal silicone oil injection can be a good option for treating MHRD in aphakic eyes if the detachment of the retina is dependent on posturing. The surgeon should consider the volume of silicone oil or postoperative posturing in the treatment of MHRD.

Long-Term Outcome After Silicone Oil Removal in Eyes with Myopic Retinal Detachment Associated with Macular Hole

Purpose

To assess the efficacy of pars plana vitrectomy (PPV) and silicone oil tamponade for management of myopic retinal detachment associated with macular hole (MRDMH) and to assess the anatomical and functional outcomes of this technique and its long-term validity after silicone oil removal.

Methods

Retrospective interventional non-comparative case series including consecutive patients who had PPV and silicone oil tamponade for MRDMH. All patients had an axial length ≥26 mm. Main outcome measures were retinal re-attachment and macular hole closure after silicone oil removal, improvement of best-corrected visual acuity (BCVA), and complications secondary to surgery. Chi square/Fisher’s exact test was used to analyze categorical variables, while One-way ANOVA/Kruskal–Wallis test was used to compare variables across the closure type and complications. Correlations between numerical variables were tested using Spearman correlation. Kaplan–Meier method was used to estimate the event-free survival. P value is significant at 0.05.

Results

The study included 26 eyes of 26 patients. Retinal re-attachment rate after primary and secondary surgeries was 88.4% and 100%, respectively. W-type macular hole closure occurred in 58% of eyes. Vision improved in 58% of eyes. Mean final BCVA was 0.05 decimal units, p = 0.004. Cataract and glaucoma developed in 42% and 15% of eyes, respectively. Initial BCVA, axial length and duration of silicone oil tamponade did not correlate significantly with either the type of macular hole closure or the final BCVA.

Conclusion

PPV and silicone oil tamponade technique promotes successful anatomical and functional outcome in MRDMH. Long-term success is maintained after silicone oil removal. High incidence of silicone oil-induced complications mandate its removal from eyes with successful retinal re-attachment.

Myopic Traction Maculopathy: A New Perspective on Classification and Management

ABSTRACT

Myopic traction maculopathy (MTM) is a complex disease affecting approximately 30% of eyes with pathologic myopia. A review of the history of treatment of MTM with success rates and limitations of different surgical techniques are reported.The pathogenesis, the definition and the management were clarified in a recent study(cit). The MTM Staging System (MSS) table summarizes all the stages of MTM offering insights on the pathogenesis and natural evolution of the disease.Guidelines of management of MTM were therefore proposed, but customized for each stage.Initial stages 1a and 2a, which define maculoschisis in the inner or inner-outer or only outer layers of the retina, should be observed. Stages 3a and 4a, defining macular detachment with and without associated schisis, should be treated with a macular buckle (MB).Stage 1b, which is a lamellar macular hole in a myopic eye, should be treated with pars plana vitrectomy (PPV) only in symptomatic cases. Stages 2b, 3b, and 4b should be treated with a MB and PPV should be added in a second step only if the presence of a lamellar macular hole requires intervention to improve visual function.Stage 1c, which is a full thickness macular hole in a myopic eye, should be treated with PPV. Stages 2c, 3c and 4c should be treated with a combination of simultaneous MB + PPV to treat both the retinal pattern of schisis or detachment and the full thickness macular hole.

COMPARISON OF THE INTERNAL LIMITING MEMBRANE INSERTION TECHNIQUE AND THE INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE WITH VITRECTOMY TO TREAT MACULAR HOLE-ASSOCIATED RETINAL DETACHMENT

PURPOSE

To compare the anatomical and functional outcomes of macular hole (MH)-associated retinal detachment after vitrectomy with the internal limiting membrane (ILM) insertion technique or the inverted ILM flap technique.

METHODS

In this retrospective observational study, we reviewed the medical records of 49 eyes with MH-associated retinal detachment that underwent vitrectomy with the ILM insertion (26 eyes) or ILM flap (23 eyes) technique.

RESULTS

The MH closure rate at 12 months was greater in the ILM flap group versus the ILM insertion group (95% vs. 73%, respectively, P = 0.059). The postoperative best-corrected visual acuity (BCVA) at 12 months was significantly better in the ILM flap group (P = 0.014). All eyes (100%) showed an improvement in the BCVA of ≥0.3 logarithm of the minimum angle of resolution (15 Early Treatment Diabetic Retinopathy Study letters) in the ILM flap group versus 20 eyes (77%) in the ILM insertion group (P = 0.026). The preoperative BCVA and the ILM flap technique were significantly correlated with the postoperative BCVA (P = 0.028 and 0.027, respectively) and BCVA improvement (≥0.3 logarithm of the minimum angle of resolution [15 Early Treatment Diabetic Retinopathy Study letters]; P = 0.003 and 0.026, respectively).

CONCLUSION

The inverted ILM flap technique was more effective in improving the postoperative BCVA in patients with MH-associated retinal detachment when compared with the ILM insertion technique. The preoperative BCVA and the ILM flap technique were independent prognostic factors for visual outcomes in patients with MH-associated retinal detachment.

Proposal for the management of myopic traction maculopathy based on the new MTM staging system

PURPOSE

To propose the Myopic Traction Maculopathy (MTM) management Table, based on the MTM Staging System (MSS).

METHODS

A retrospective review of 157 eyes affected by MTM, operated with pars plana vitrectomy (PPV), or macular buckle (MB) or combined surgery (MB + PPV). Each case was classified according to the MSS. Anatomical results were evaluated with OCT at an intermediate follow-up (3-6 months) and at a final follow-up (2-8 years), considering changes both in the foveal and in the retinal pattern. The number and type of operations needed were noted. The surgical complications were reported.

RESULTS

Primary surgery was MB for 83 eyes (52%), PPV for 36 (23%) and MB + PPV for 38 (24%). At intermediate follow-up, the retinal pattern was restored in 55.41% and foveal in 42.68%.Further surgery was indicated as PPV in 25.48%, MB in 14.65%. At the final follow-up, the retinal pattern was restored in 96.16% and the foveal pattern in 87.90%.BCVA improved at the final follow-up (p < 0.05). The complications of MB were not sight-threatening. The complications of PPV were FTMH in 67% cases in stages 2, 3, and 4. Cataract developed in 60% of phakic eyes. The complications of combined MB+PPV were cataract (56%) and PVR (5%).

CONCLUSIONS

Both PPV and MB may be used to treat MTM. PPV addresses the changes in the foveal pattern while MB addresses the changes in the retinal pattern. The MTM management table offers a proposal for the choice of type and timing of treatment customized per each stage of MTM.

Successful Technique for Closure of Macular Hole Retinal Detachment Using Autologous Retinal Transplant

Macular hole retinal detachment (MHRD) for the most part develops in highly myopic eyes. Several surgical methods have been introduced to treat MHRD. We describe our experience with the autologous retinal transplant in patient with MHRD. A 49-year-old female presented with a 2-week history of a sudden decrease in the central vision in the right eye (RE). A 3-port, 25-gauge pars plana vitrectomy was performed with the ILM dye staining and peeling. Endodiathermy was applied around a 1.5-disc diameter neurosensory donor site in the supertemporal retina. The graft was cut with standard 25-gauge curved scissors. Perfluoro-n-octane (PFO) was instilled. The free graft was gently handled until its packing into the macular hole. Two months following the initial PPV, the macular hole was closed, and vision improved from 0.05 to 0.25 logMAR.

Myopic Traction Maculopathy: Diagnostic and Management Strategies

Pathologic myopia (PM) is an ocular disorder characterized by a spherical equivalent (SE) of more than - 6.0 diopters (D) or by an axial length (AL) of more than 26.5 millimeters (mm). PM is associated with myopic maculopathy (MM). The ATN classification describes all the aspects of MM which regroups atrophic, tractional and neovascular consequences to the sclera, choroid and retina of highly myopic eyes. The advent of OCT allowed to define the ultrastructural characteristics of the tractional changes in MM, described by the term myopic traction maculopathy (MTM). They include foveoschisis/maculoschisis/retinoschisis (FS/MS/RS), retinal/foveal detachment (RD/FD), lamellar macular holes (LMH) and full-thickness macular holes (FTMH) with or without RD (MHRD). The MTM staging system (MSS) describes all foveal and retinal changes related to MTM and their natural history interpreting them as different stages of a single progressive disorder. The management of MTM can be just observation for the earliest cases with good vision or surgery for the severe stages with vision loss. There are two possible surgical approaches: ab externo, that acts on the alteration of the scleral shape and includes posterior scleral reinforcement and macular buckle. Ab interno, that targets the alteration of the foveal profile and consists in pars plana vitrectomy with removal of all the epiretinal tractions, maneuvers on the internal limiting membrane, and the use of intravitreal tamponade and laser. As they target two different sides of the same pathology, the two techniques have to be selected on the base of the MTM stage, single or combined.

Long-term follow-up of primary silicone oil tamponade for retinal detachment secondary to macular hole in highly myopic eyes: a prognostic factor analysis

PURPOSE

To investigate the risk factors associated with retinal detachment recurrence after first vitrectomy in high myopic eyes with macular hole retinal detachment (MHRD).

METHODS

Patients with high myopic eyes with MHRD who underwent pars plana vitrectomy and silicone oil (SO) tamponade with a follow-up period more than 12 months and more than 3 months after SO removal were included in this retrospective study. Logistic regression was performed to determine the risk factors associated with retinal re-detachment.

RESULTS

A total of 45 eyes from 43 patients were included in this study (11 male and 34 female patients). The retinal re-detachment rate after the first removal of silicon oil was 35.5% (16/45) in a mean postoperative follow-up time of 35.64 ± 32.94 months. Complete macular atrophy on fundus photography (odds ratio (OR) = 17.021, 95% confidence interval (95% CI): 2.218-130.609, p = 0.006) was a risk factor for MHRD after SO removal, while internal limiting membrane (ILM) peeling (OR = 0.091, 95% CI: 0.013-0.633, p = 0.015) and duration of SO tamponade (OR = 0.667, 95% CI: 0.454-0.980, p = 0.039) were protective factors.

CONCLUSION

For high myopic eyes with MHRD, complete macular atrophy was a significant risk factor for retinal re-detachment after silicon oil removal. ILM peeling and the duration of silicon oil tamponade were protective factors.

Effects of perfluorocarbon liquids in macular hole retinal detachment treatment

OBJECTIVE

This study aims to evaluate the clinical efficacy and visual function prognosis of macular hole retinal detachment treatment for high myopia by inverting the internal limiting membrane to overlay the macular hole with the assistance of perfluorocarbon liquids.

METHODS

A total of 55 high myopia patients, who received macular hole retinal detachment treatment from 2013 to 2016, were included in this study. Among these patients, 38 patients were assigned to the first group and 17 patients (perfluorocarbon liquids) were assigned to the second group. The second group was further divided into two subgroups, according to the overlaying layer number of the internal limiting membrane valve: A group (multiple layers) and B group (single layer).

RESULTS

The success rate of the internal limiting membrane inversion and overlaying on the macular hole was 23.68% and 100% in the first and second group, respectively. The differences in macular hole closing rate and postoperative best-corrected visual acuity between these two groups were statistically significant (p < 0.05). Furthermore, the differences in macular morphology recovery between the A and B groups were also statistically significant (p = 0.004 < 0.05).

CONCLUSION

Perfluorocarbon liquids play a positive role in the operation process of the internal limiting membrane.

Long-term Outcomes of Macular Hole Retinal Detachment in Highly Myopic Eyes after Surgical Reattachment

PURPOSE

To evaluate visual acuity changes over 3 years following surgical reattachment of macular hole retinal detachment (MHRD) developed in high myopia.

METHODS

A retrospective analysis was performed using the medical records of patients with highly myopic eyes who underwent pars plana vitrectomy with internal limiting membrane peeling or the internal limiting membrane flap technique for MHRD. Changes in best-corrected visual acuity (BCVA) were measured at baseline, 6 months, 1 year, 2 years, and 3 years.

RESULTS

Of the 22 eyes analyzed, macular hole was closed in 13 and unclosed in nine. BCVA significantly improved from 1.61 ± 0.39 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.17 ± 0.43 logMAR at 6 months and 1.33 ± 0.48 logMAR at 2 years after MHRD surgery. At 3 years, BCVA significantly decreased compared with that at 6 months, and visual improvement from baseline was not significant. BCVA and proportion of vision loss ≥0.3 logMAR were not different between the closed and unclosed macular hole groups.

CONCLUSIONS

Visual improvement after surgical reattachment of MHRD in high myopia was not maintained, and favorable macular hole closure effects were not observed at 3-year follow-up.

Combined Vitrectomy With Macular Buckling In High Myopic Eyes With Macular Hole Retinal Detachment: A Pilot Study Of A Novel Snail-Tipped Exoplant

Purpose

To evaluate the efficacy of a novel snail-tipped exoplant for macular buckling combined with vitrectomy in high myopic eyes with macular hole retinal detachment.

Patient and methods

A novel exoplant was simply prepared with a 5 × 3 mm silicone sponge strengthened in the center with a malleable titanium plate. One end was bent to make a rolled tip like a snail shell to be placed under the macula. Combined vitrectomy with macular buckling using this exoplant was performed in eight consecutive cases. The long arm of the exoplant was manipulated manually to fit the curvature of the eyeball and the length was trimmed appropriately after scleral suturing of the exoplant.

Results

Retinal reattachment was achieved in all cases (100%) and macular hole closure was confirmed in 6 eyes (75%). The mean best-corrected visual acuity improved from 1.53 ± 0.73 LogMAR preoperatively to 1.14 ± 0.59 LogMAR to postoperatively (p = 0.063). The mean pre- and postoperative AL was 28.44 ± 1.86 mm and 27.60 ± 1.83 mm, respectively (p = 0.016). The mean follow-up period was 15.4 months and no buckle-related complications such as diplopia, infection or exposure of the exoplant were noticed during the period.

Conclusion

This exoplant could easily be prepared with readily available materials in the operating room and it was well tolerated with favorable anatomic results in high myopic eyes. Further studies of increased number of patients with long-term follow-up will be necessary.

Optical coherence tomography patterns and outcomes of contusion maculopathy caused by impact of sporting equipment

Background

To describe the patterns and outcomes of contusion maculopathy after ocular contusions resulting from accidental impact with sporting equipment.

Methods

We conducted a retrospective study of interventional case series. Patient Population: Twenty-one eyes of 21 patients who sustained blunt ocular trauma while playing a sport. Intervention/Observation Procedure(s): Surgery or observation by optical coherence tomography (OCT). Main Outcome Measure(s): The morphologic changes within the macula in the early stages after injury and changes in visual function in the early and recovery stages after injury.

Results

In the early stage, OCT visualized four injury patterns: type Ι, commotio retinae (14.3%, 3 eyes) with increased reflectivity of the ellipsoid zone and retinal pigment epithelium; type II, incomplete macular hole(38.1%, 8 eyes) with three structural changes, i.e., a partial V-shaped macular hole, a jar-shaped macular hole with retinal tissue at the bottom, and a connective bridge attached to retinal tissues; type III, full-thickness macular hole (33.3%, 7 eyes); and type IV, foveal hemorrhage (14.3%, 3 eyes). During recovery, OCT images of types Ι and II showed almost normal macular morphology with better visual acuity (mean ± SD,0.02 ± 0.1 and 0.14 ± 0.21logMAR.). In types III and IV, the visual prognosis was poor (0.52 ± 0.34 and 0.22 ± 0.16), OCT images showed retinal atrophy at the fovea despite vitrectomy and sulfur hexafluoride (SF6) gas tamponade.

Conclusion

Early OCT images identified four patterns of contusion maculopathy with different treatment outcomes. In types Ι and II, the visual function and retinal morphology remained intact. With types III and IV, respectively, the treatments of vitrectomy and SF6 gas tamponade for patients were effective.

Macular buckle without vitrectomy for myopic macular schisis: a Canadian case series

OBJECTIVE

To determine the effectiveness of a macular buckle procedure without vitrectomy for the treatment of symptomatic myopic macular schisis.

DESIGN

Retrospective case series.

PARTICIPANTS AND METHODS

All patients who underwent surgery with placement of an NPB macular buckle (AJL Ophthalmic, Miñano, Álava, Spain) without vitrectomy for symptomatic myopic macular schisis were included. Visual acuity and anatomical outcomes based on optical coherence tomography (OCT) were reviewed.

RESULTS

Eight consecutive eyes from 7 patients were included. Six of the 7 patients were female and the mean age was 59 ± 6 years (range, 49-66 years). The mean follow-up duration was 11 ± 7 months (range, 3-23 months). Mean preoperative axial length was 29.54 ± 1.28 mm (range, 27.88-31.96 mm). Mean preoperative best-corrected visual acuity (BCVA) was 0.71 ± 0.29 logMAR (Snellen equivalent 20/103); mean postoperative BCVA was 0.46 ± 0.44 (Snellen equivalent 20/58; p = 0.19) and 87.5% of patients maintained or improved vision. Pre- and postoperative OCT images are included and discussed within. Preoperative ellipsoid zone status and postoperative central macular buckle indentation appear to be important in visual outcomes. Two patients required a buckle repositioning for persistent schisis. One patient developed a macular hole postoperatively that resolved with subsequent vitrectomy. There were no other complications.

CONCLUSIONS

The macular buckle is an effective and promising therapeutic option for myopic macular schisis.

Macular buckle technique in myopic traction maculopathy: a 16-year review of the literature and a comparison with vitreous surgery

PURPOSE

The aim of this study is to review anatomical and functional outcomes following macular buckling (MB) in high myopia and to compare such results with those obtained by pars plana vitrectomy (PPV).

METHODS

PubMed articles on MB in high myopia (2000-2016) were reviewed. Main outcomes included retinal reattachment and macular hole (MH) closure rates, resolution of myopic foveoschisis (MFS), and postoperative visual acuity.

RESULTS

Thirty-one articles included 16 in patients with retinal detachment due to MH (MHRD group), 11 in MFS with or without foveal detachment (MFS group), and 4 in MH patients with MFS (MH-MFS group). Surgical techniques mainly differed in the type of buckle, rectus muscles involvement, and concurrent PPV. In eyes with persistent MH, prognosis in the MHRD and MH-MFS groups differed between eyes receiving MB compared to PPV: functional outcome was markedly poorer and there was a higher risk of retinal redetachment associated with PPV. In the MSF group, secondary MHs were more likely to develop in eyes treated with PPV and internal limiting membrane peeling than those undergoing MB alone or combined with PPV. Retinal pigment epithelium changes, malpositioning, perforation, and choroidal detachment were the main complications.

CONCLUSIONS

Although different approaches are used, complete resolution of foveoschisis, retinal reattachment, and MH closure seem to be achieved more frequently with MB than PPV.

Floating flap of internal limiting membrane in myopic macular hole surgery

PURPOSE

To evaluate the surgical results of macular hole (MH) in patients with high myopia treated with pars plana vitrectomy (PPV) leaving the internal limiting membrane (ILM) flap floating in vitreous fluid at the edge of the MH.

METHODS

Nine highly myopic eyes with MH of nine consecutive patients who underwent PPV were retrospectively evaluated. Three eyes were accompanied by retinal detachment (RD). ILM peeling was performed around the MH and some part of the ILM flap was left attached to the edge of the MH. Further manipulation of the ILM flap to cover the MH was not performed. Fluid-gas exchange was performed to the retinal vessel arcade level. Patients maintained a face down position for 3 to 7 days postoperatively.

RESULTS

Complete MH closure was confirmed using optical coherence tomography in all eyes and three eyes with RD showed reattachment of the retina after the initial surgery. Visual acuity significantly improved (P = 0.02) and no eyes experienced MH reopening or RD occurrence during the follow-up period of 8.33 ± 3.61 months after the surgery.

CONCLUSIONS

MH with or without RD in highly myopic eyes could be successfully treated with PPV leaving ILM flap floating in vitreous fluid at the edge of the MH. After the ILM peeling, further manipulation of the ILM flap to cover the MH would not be necessary for the treatment of MH in high myopia.

Morphological analysis and quantitative evaluation of myopic maculopathy by three-dimensional magnetic resonance imaging

PurposeTo study the characteristic morphology and quantitatively evaluate the eye shape in different types of myopic maculopathy.MethodsA total of 103 eyes from 65 patients with high myopic maculopathy were examined by spectral-domain optical coherence tomography (SD-OCT) and three-dimensional magnetic resonance imaging (3D MRI). The participants were classified into two groups, namely myopic traction maculopathy (MTM) eyes and non-MTM eyes, with SD-OCT imaging. Volume renderings and morphology analysis of the 3D MRI of the eyeball were obtained. Quantitative analysis was achieved in the calculation of vitreous volume and the three-dimensional diameters of the eyeball in three cardinal axes. The eye shape distribution and the diameters of the eyeball were compared between the two groups. Eye shape distribution, vitreous volume, and eyeball diameter were compared between MTM and non-MTM eyes.ResultsThe MTM and non-MTM groups had a total of 68 and 35 eyes, respectively. A significant difference was found in the eye shape distribution (P<0.0001) between MTM and non-MTM eyes. Most of the MTM eyes had undergone a non-uniform expansion of the eyeball, whereas the non-MTM eyes had expanded uniformly. There was no significant difference (P>0.05) in either vitreous volume or other diameters between the two groups.ConclusionsNon-uniform globe expansion and staphyloma formation might play an important role in the pathogenesis of MTM.

Macular Buckling Surgery for Retinal Detachment Associated with Macular Hole in High Myopia Eye

A 68-year-old woman presented to our clinic with a 1-month history of central scotoma and visual loss in her right eye. The best corrected visual acuity (BCVA) was hand motion in her right eye. Fundus examination showed myopic chorioretinal degeneration in association with posterior staphyloma and the retina was slightly elevated throughout the macula. Optical coherence tomography (OCT) revealed retinal detachment involving the posterior pole with a macular hole and staphyloma. The patient underwent pars plana vitrectomy, internal limiting membrane peeling, macular buckling, and perfluoropropane gas tamponade. At 3-month follow-up, her BCVA was improved to counting fingers at 1 meter and flattened retina with closed macular hole was observed by OCT. Myopic macular hole with retinal detachment associated with posterior staphyloma represent a challenge regarding their management and several surgical techniques have been described. Although satisfactory anatomical improvement is achieved in these eyes after surgery, the visual acuity outcomes may be poorer than expected due to the chorioretinal atrophy at the posterior pole.

Clinical Investigation of the Posterior scleral contraction to Treat Macular Traction Maculopathy in Highly Myopic Eyes

Myopic traction maculopathy (MTM) can cause vision disabilities in highly myopic eyes. This retrospective case series investigated the clinical outcomes of posterior scleral contraction (PSC) using genipin-cross-linked sclera as the material to treat MTM in highly myopic eyes. In total, 32 eyes from 29 highly myopic patients who underwent PSC for MTM were recruited. The changes in best-corrected visual acuity (BCVA) and axial length were evaluated, macular reattachment and macular hole (MH) closure was assessed by optical coherence tomography, and complications were evaluated. At the final follow-up, the retina was completely reattached in 25 eyes (78.1%), essentially reattached in 4 eyes (12.5%), and partially reattached in 3 eyes (9.4%). The logMAR BCVA improved significantly from 1.18 ± 0.45 preoperatively to 0.87 ± 0.45 postoperatively (P < 0.001). The 32 eyes were further divided into the MH group (16 eyes) and the non-MH group (16 eyes) for comparison. The MH was closed in 9 eyes (56.3%). The retinal reattachment rate was 75.0% in the MH group and 81.25% in the non-MH group, and the logMAR BCVA improved significantly in both groups. The PSC using genipin-cross-linked sclera as the material can effectively treat MTM in highly myopic eyes, and significant visual improvement can be achieved with minimal complications.

Long-term surgical outcomes of the inverted internal limiting membrane flap technique in highly myopic macular hole retinal detachment

BACKGROUND

Pars plana vitrectomy (PPV) procedures are used for the surgical treatment of macular hole retinal detachment (MHRD) associated with high myopia. Re-detachment of the retina has been reported in MHRD associated with high myopia. Our aim was to evaluate the 1-year outcomes of vitrectomy, performed using an inverted internal limiting membrane (ILM) flap technique with gas tamponade, in five cases of MHRD associated with high myopia.

METHODS

We performed a retrospective review of medical records of five consecutive cases of highly myopic MHRD. The following postoperative data were collected: refractive error, best-corrected visual acuity, intraocular pressure, ophthalmic fundus examination findings, ocular coherence tomography at 1, 3, 6, and 12 months postoperatively; duration of the follow-up period; and intra- and postoperative complications. The primary endpoint of the study was the rate of postoperative retinal reattachment and macular hole (MH) closure. Paired t-tests were conducted to evaluate postoperative changes.

RESULTS

Mean visual acuity improved significantly (P = 0.008), with an improvement of ≥2 lines on LogMAR value gained in three of the five eyes. Retinal reattachment was maintained in all cases, with no cases of MH reopening identified over the mean follow-up period of 20.2 months. No complications were identified in any eye.

CONCLUSIONS

The inverted ILM flap technique and gas tamponade provided primary retinal reattachment and MH closure over the ≥12-month follow-up period.

Inverted internal limiting membrane flap technique as a useful procedure for macular hole-associated retinal detachment in highly myopic eyes

PurposeTo determine whether the inverted internal limiting membrane (ILM) flap technique contributes to high reattachment and closure rates in patients with macular hole-associated retinal detachment (MHRD).Patients and methodsIn all, 15 eyes of 15 patients with MHRD undergoing 25-gauge pars plana vitrectomy with the inverted ILM flap technique or ILM peeling. The patients were divided into the inverted ILM flap technique group (6 eyes) and ILM peeling group (9 eyes). The logarithm of minimal angle of resolution best-corrected visual acuity (BCVA) and retinal attachment and macular hole closure rates were compared between the two groups before and after surgery.ResultsNo significant differences were found in the pre- and postoperative BCVA at 1 and 3 months after surgery in either group (inverted ILM flap technique group, preoperatively 1.04±0.55, 1 month 0.95±0.30, 3 months 0.83±0.22; ILM peeling group, preoperatively 1.00±0.44, 1 month 1.05±0.38, 3 months 1.06±0.49; P>0.05, respectively). The postoperative BCVA at 6 months after surgery was significantly better in the inverted ILM flap technique group than in the ILM peeling group (inverted ILM flap technique group, 0.62±0.35; ILM peeling group, 1.02±0.41, P=0.045). The improvement in BCVA was significantly better in the inverted ILM flap technique group than in the ILM peeling group (inverted ILM flap technique group, -0.41±0.29; ILM peeling group, 0.02±0.36; P=0.021). The primary macular hole closure rates were 100% in the inverted ILM flap technique group and 55.5% in the ILM peeling group. The primary reattachment rates were 100% in the inverted ILM flap technique group and 55.5% in the ILM peeling group. The primary macular hole closure and reattachment rates were not significantly different in both groups (P=0.056, respectively).ConclusionThe inverted ILM flap technique is a useful procedure for MHRD in highly myopic eyes.

T-shaped macular buckling combined with 25G pars plana vitrectomy for macular hole, macular schisis, and macular detachment in highly myopic eyes

OBJECTIVE

To report our experience using the T-shaped macular buckle (MB) with or without pars plana vitrectomy (PPV) as primary surgery or with a previous failed surgical approach in patients affected by high myopia and macular hole (MH) with or without macular detachment and with or without macular schisis. The primary goal was to evaluate complete closure of the MH and reattachment of the retina.

DESIGN

Retrospective case series of 21 consecutive patients who underwent T-shaped MB implant alone or combined with PPV at the Academic Medical Center in Amsterdam, The Netherlands, between January 2013 and November 2014. The mean axial length was 31.22 mm. The mean follow-up period was 7 months.

RESULTS

Retinal reattachment was achieved in 100% of cases while MH closure was achieved in 90.5%. No major perioperative complications were observed. Best corrected visual acuity improved in 71.4% of patients.

CONCLUSIONS

MB combined with PPV should be considered as the preferred surgical approach both in primary and recurrent retinal detachment secondary to MH in high myopic eyes.

Visual Recovery after Primary Retinal Detachment Surgery: Biofeedback Rehabilitative Strategy

Purpose. To evaluate possible speeding up recovery time after retinal detachment (RD) surgery using biofeedback strategy. Methods. A total of 52 eyes were selected. After surgery, patients were divided into two groups: group A, including patients submitted to biofeedback with MP-1 strategy; group B, patients who received common care strategy. Biofeedback strategy was started 15 days after the suspension of cycloplegic eye drops in buckling procedure or after silicone oil removal in the vitrectomized eyes. Controls were scheduled at baseline and 6, 12, and 18 weeks. Results. At baseline, there was no significant difference in BCVA between groups (P = 0.4230). At the end of biofeedback treatment (WK 6) BCVA of group A was significantly better (P < 0.001) than group B and BCVA was still better in group A than group B at WK 12 (P = 0.028) and at WK 18 (P = 0.041). Conclusions. Visual recovery after RD surgery is still unclear, and it does not depend on entity of the RD. Our data demonstrate that in biofeedback group there was a significant recovery in visual performances that still remains evident after 3 months from the baseline.

A Comparative Study between Vitrectomy with Internal Tamponade and a New Modified Fiber Optic Illuminated Ando Plombe for Cases of Macular Hole Retinal Detachment in Myopic Eyes

Aim. To compare pars plana vitrectomy (PPV) with silicone tamponade or gas (Groups Ia and Ib) and a new modified Ando plombe equipped with a fiber optic light (Group II) for cases with macular hole retinal detachment (MHRD) in high myopic eyes (axial length > 26 mm). Methods. A prospective interventional randomized case series included 60 eyes (20 in each group). Successful outcome was considered if the retina was completely attached at the end of the follow-up period. Complications were identified for each group. Results. Visual acuity improved by 37.31%, 40.67%, and 49.40% in Groups Ia, Ib, and II, respectively. The success rate was 55%, 60%, and 100% in Groups Ia , Ib, and II, respectively, with a statistically significant difference between Groups Ia, Ib, and II (p < 0.001 in Ia, p: 0.002 in Ib). Complications rates were 60%, 45%, and 20% in Groups Ia, Ib, and II, respectively, with a statistically significant difference between Groups Ia and II (p: 0.01). Conclusion. Fiber optic illuminated Ando plombe allows better positioning under the macula and consequently improves the success rate of epimacular buckling in comparison to PPV with internal tamponade in MMHRD.

Autofluorescence and axial length as prognostic factors for outcomes of macular hole retinal detachment surgery in high myopia

PURPOSE

To evaluate the results of fundus autofluorescence and axial length as prognostic factors for surgical outcome of macular hole retinal detachment in high myopic patients.

METHODS

This is a retrospective, interventional, nonrandomized study. Patients were treated with posterior vitrectomy, internal limiting membrane peeling, and silicone oil tamponade. Best-corrected visual acuity, axial length, fundus autofluorescence, and spectral domain optical coherence tomography images were obtained.

RESULTS

Fifteen eyes from 15 patients (mean age, 69.4 years) were evaluated. The mean refractive error was -19 diopters, and the mean axial length was 29.9 mm. The mean best-corrected visual acuity (logMAR) improved from 2.17 to 1.42 (P = 0.02) after a mean follow-up of 19.3 months. Spectral domain optical coherence tomography scans showed retinal detachment resolution in 13 eyes (86.6%) and macular hole closure in 9 eyes (60%). Fundus autofluorescence showed macular hypoautofluorescence with foveal involvement (mean area of 9.7 mm2) in 10 eyes (66.6%). Postoperative best-corrected visual acuity was significantly worse in these eyes (P = 0.009). Axial length >30 mm was found in the 2 cases with recurrent retinal detachment and in 4 of the 6 cases without macular hole closure (66.6%).

CONCLUSION

Macular hole retinal detachment in high myopic patients can be successfully treated with vitrectomy, internal limiting membrane peeling, and silicone oil. Axial length >30 mm and macular hypoautofluorescence with foveal involvement seem to be prognostic factors for a worse anatomical and visual outcome.

Vitrectomy with internal limiting membrane peeling vs no peeling for Macular Hole-induced Retinal Detachment (MHRD): a meta-analysis

BACKGROUND

we conducted our meta-analysis of published studies to assess existing evidence about the efficacy and safety of vitrectomy with ILM peeling vs. that of vitrectomy with no ILM peeling for Macular hole-induced retinal detachment.

METHODS

Databases, including Pubmed, Cochrane Library, Ovid, Web of Science, Wanfang and CNKI, were searched to identify studies comparing outcomes following vitrectomy with ILM peeling and that with no ILM peeling for macular hole-induced retinal detachment. The meta-analysis was performed by RevMan 5.1.

RESULTS

Six comparative studies comprising 180 eyes were identified. It was indicated that the rate of retinal reattachment (Odds ratio (OR) = 3.03, 95 % Confidence interval (CI):1.35 to 6.78; P = 0.007) and macular hole closure (OR = 6.74, 95 % CI:3.26 to 13.93; P < 0.001) after initial surgery was higher and the rate of recurrent retinal detachment (OR = 0.08, 95 % CI:0.02 to 0.30; P = 0.0002) was lower in the group of vitrectomy with ILM peeling than that in the group of vitrectomy with no ILM peeling. However, the improved BCVA (Weighted mean difference (WMD) = 0.14, 95 % CI: -0.20 to 0.47; P = 0.42) and the rate of postoperative complications were similar between the two groups.

CONCLUSION

Vitrectomy with internal limiting membrane peeling is an efficient and safe procedure for macular hole-induced retinal detachment.

Treatment of retinal detachment secondary to macular hole in highly myopic eyes: pars plana vitrectomy with internal limiting membrane peel and silicone oil tamponade

PURPOSE

To evaluate efficacy of vitrectomy with internal limiting membrane peel and silicone oil tamponade in highly myopic eyes with retinal detachment secondary to macular hole (MH).

METHODS

Twenty-one consecutive cases of MH-retinal detachment in highly myopic eyes were retrospectively reviewed. Eyes underwent pars plana vitrectomy, internal limiting membrane peeling, and silicone oil tamponade. A face-down or side-lying position was maintained postoperatively. Silicone oil was removed 3 months to 12 months later. Outcomes included MH closure and retinal reattachment rates, best-corrected visual acuity, and complication rates.

RESULTS

Mean patient age was 59.3 ± 6.5 years and mean spherical equivalent was -15.2 ± 4.3 diopters. After silicone oil removal, 18 eyes (86%) had MH closure with retinal reattachment and 2 eyes needed reattachment with endolaser photocoagulation and fluid/gas exchange, and 1 patient refused further treatment. At the last follow-up, median best-corrected visual acuity was +1.48 ± 0.12, up from preoperative +2.11 ± 0.17 (P = 0.03). Transient intraocular pressure elevation was observed in 11 eyes (52%). Iatrogenic retinal break occurred in one case.

CONCLUSION

Combining pars plana vitrectomy with internal limiting membrane peel and silicone oil tamponade was safe and effective in treating MH-retinal detachment in highly myopic eyes. Silicone oil tamponade may improve initial anatomical success rates because of longer tamponade duration.

Retrospective Comparison of 25- and 23-Gauge Microincision Vitrectomy Surgery and 20-Gauge Vitrectomy for the Repair of Macular Hole Retinal Detachment

PURPOSE

To compare the anatomical and functional outcomes of 25- and 23-gauge microincision vitrectomy surgery (25G and 23G MIVS) instrumentation with the standard 20G pars plana vitrectomy (20G PPV) system in the treatment of primary macular hole retinal detachment (MHRD).

DESIGN

A retrospective comparative study.

METHODS

Forty-six eyes of 45 patients with MHRD underwent pars plana vitrectomy from March 1, 2006 to April 31, 2011. Fourteen, 13, and 19 eyes underwent 20G PPV, 23G MIVS, and 25G MIVS, respectively. The analysis included characteristics of the patients, single operation reattachment rate, final reattachment rate, closure rate of the macular hole, and rate of complications. The median follow-up period was 273 days.

RESULTS

Preoperative characteristics were similar in the 3 groups. The single operation success rate was 11 (79%) of 14 for 20G PPV, 10 (77%) of 13 for 23G MIVS, and 14 (74%) of 19 for 25G MIVS (P = 0.95). The closure rate of the macular hole was 9 (64%) of 14 for 20G PPV, 9 (69%) of 13 for 23G MIVS, and 11 (58%) of 19 for 25G MIVS (P = 0.78). One hundred percent of patients achieved final reattachment after multiple surgeries, excluding 2 patients who dropped out during the follow-up period. Rates of visual recovery and complications, including hypotony, were similar for all 3 procedures.

CONCLUSIONS

The outcomes of 25G and 23G MIVS for the management of MHRD did not differ significantly from 20G PPV. Microincision vitrectomy surgery may be considered an alternative treatment, even for MHRD.

Effect of 360° episcleral band as adjunctive to pars plana vitrectomy and silicone oil tamponade in the management of myopic macular hole retinal detachment

PURPOSE

To report the effect of 360° scleral band in combination with pars plana vitrectomy (PPV) and silicone oil tamponade on the anatomical success and on the closure of macular hole (MH) in cases of myopic macular hole retinal detachment.

METHODS

A retrospective consecutive interventional study from medical records on patients who had pars plana vitrectomy and silicone oil. with or without 360° scleral band for the treatment of retinal detachment associated with MH. The cases were operated in the period from February 2006 to May 2012. The included cases were classified into two groups: the first group with scleral band and the second group without scleral band. The primary anatomical success and optical coherence tomography patterns of MH closure were the main outcomes.

RESULTS

After the first procedure, the overall success rate was 90.6% (in both groups). In 9.4%, there was recurrent retinal detachment. In the first group the success rate was 89.5%, and in 10.5% there was recurrent retinal detachment. In the second group 92.5% was success and 7.5% was recurrent retinal detachment. After the second interference, the success rate was 98.4% in both groups. Closure of MH was achieved in 45.2% in both groups. In the first group, there was closure of MH in 43.5%, while in 47.8% the hole remained open flat, in 4.3% the hole closed partially and in 4.3% there was macular scar. In the second group, MH closure was achieved in 47.4%, whereas in 52.6% the hole was open flat.

CONCLUSION

The use of 360° band in combination with pars plana vitrectomy and silicone oil offered no additional effect on either the anatomical success or the rate of MH closure in the management of myopic macular hole retinal detachment. Four patterns of MH were reported closed MH, partial thickness MH, open flat MH, and macular scar.

Macular buckling for previously untreated and recurrent retinal detachment due to high myopic macular hole: a 12-month comparative study

PURPOSE

To evaluate postoperative outcomes after macular buckling together with pars plana vitrectomy (PPV) in previously untreated and recurrent retinal detachment secondary to macular hole (MH) in highly myopic eyes.

METHODS

In a retrospective cohort study, 42 eyes of 42 high myopic patients with retinal detachment due to MH were evaluated. Patients were divided into previously untreated retinal detachment (group 1, 21 eyes) and recurrent retinal detachment (group 2, 21 eyes). Macular buckling and PPV were performed in all patients. Main outcomes included retinal reattachment rate, macular hole closure rate and best-corrected visual acuity (BCVA) at 3, 6, and 12 months. Optical coherence tomography (OCT) was performed both pre- and postoperatively in all patients to assess the anatomical status of the macula.

RESULTS

Primary retinal reattachment rate in group 1 was 95% (20/21), which increased to 100% (21/21) after a second surgery. MH closure was achieved in 81% of patients (17/21) after one surgery. The mean preoperative BCVA (logarithm of the minimum angle of resolution, LogMAR) improved from 1.32 (95% CI 1.19;1.44) to 0.76 (95% CI 0.56;0.96) 12 months postoperatively. In all except one case, gas tamponade was preferred. Primary reattachment and MH closure rate in group 2 were 90.5% (19/21) and 57% (12/21) respectively, and did not improve after a second surgery. Preoperative BCVA (LogMAR) was 1.39 (95% CI 1.29;1.49) and improved to 0.95 (95% CI 0.75;1.15) at 12 months. Silicone oil tamponade was used in seven of 21 patients, and finally was removed in five of them.

CONCLUSIONS

Macular buckling combined with PPV should be considered a preferred surgical approach both in primary and recurrent retinal detachment secondary to MH in high myopic eyes. Nevertheless, visual outcomes seem to be better when macular buckling is chosen as first-line treatment.

Prognostic factor analysis of vitrectomy for retinal detachment associated with myopic macular holes

PURPOSE

To describe the anatomic and functional outcomes in a cohort of subjects undergoing vitrectomy for retinal detachment (RD) resulting from myopic macular hole (MH) and to analyze the prognostic and surgical factors predicting retinal reattachment and MH closure.

DESIGN

Retrospective case series.

PARTICIPANTS

All patients who underwent vitrectomy for RD resulting from myopic MH between 2000 and 2009 at our center.

METHODS

Case records were reviewed at 6 months after surgery. Retinal reattachment and complete anatomic success, defined as retinal reattachment with MH closure, were assessed. Multivariate logistic regression models, including age, gender, duration of symptoms, spherical equivalent refraction (SE), internal limiting membrane peeling, tamponade choice, and concurrent scleral buckling, were constructed to assess associations with covariates.

MAIN OUTCOME MEASURES

Retinal reattachment and complete anatomic success (retinal reattachment with MH closure).

RESULTS

In total, 114 subjects were analyzed. Most were women (n = 79 [69.3%]), and the mean age was 57.5±13.3 years. The mean SE was -9.88±6.37 diopters. At 6 months, 98 subjects (86.0%) demonstrated retinal reattachment, of whom 93 subjects required only 1 operation. Complete anatomic success was achieved in 61 subjects (53.5%), of whom 55 needed only 1 operation. Subjects with retinal reattachment had better best-corrected visual acuity (BCVA; mean BCVA, 1.22±0.81 logarithm of the minimum angle of resolution [logMAR] units) than those without (mean BCVA, 1.98±1.26 logMAR units; P < 0.001), and subjects with complete anatomic success had better BCVA (mean BCVA, 1.05±0.87 logMAR units) than those without (mean BCVA, 1.62±0.87 logMAR units; P < 0.001). In multivariate analyses, increasing age and the use of perfluoropropane (C3F8) tamponade were predictive of anatomic success (per 1-year increase: odds ratio [OR], 1.049; 95% confidence interval [CI], 1.002-1.099; P = 0.04; and for tamponade: OR, 10.71; 95% CI, 1.08-106.29; P = 0.04).

CONCLUSIONS

Vitrectomy is effective in the repair of RD resulting from MH in myopic eyes, with retinal reattachment achieved more frequently than MH closure. Retinal reattachment and MH closure are important for improving visual outcomes. Greater age at presentation and use of C3F8 are associated with a greater likelihood of anatomic success.
