RESUMO
PURPOSE: To describe characteristics of the vitreomacular interface (VMI) in traumatic macular holes (TMH) compared to idiopathic macular holes (IMH) using immunofluorescence and electron microscopy, and to correlate with clinical data. METHODS: For immunocytochemical and ultrastructural analyses, premacular tissue with internal limiting membrane (ILM) and epiretinal membrane (ERM) was harvested during vitrectomy from 5 eyes with TMH and 5 eyes with IMH. All specimens were processed as flat mounts for phase-contrast microscopy, interference and fluorescence microscopy, and transmission electron microscopy (TEM). Primary antibodies were used against microglial and macroglial cells. Clinical data was retrospectively evaluated. RESULTS: Surgically excised premacular tissue of eyes with TMH showed a less pronounced positive immunoreactivity for anti-glutamine synthetase, anti-vimentin and anti-IBA1 compared to eyes with IMH. Cell nuclei staining of the flat-mounted specimens as well as TEM presented a lower cell count in eyes with TMH compared to IMH. All detected cells were found on the vitreal side of the ILM. No collagen fibrils were seen in specimens of TMH. According to patients' age, intraoperative data as well as spectral-domain optical coherence tomography (SD-OCT) analysis revealed an attached posterior vitreous in the majority of TMH cases (60%), whereas all eyes with IMH presented posterior vitreous detachment. CONCLUSION: The vitreomacular interface in TMH and IMH shows significant differences. In TMH, glial cells are a rare finding on the vitreal side of the ILM.

PURPOSE: To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH). METHODS: By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS). RESULTS: The healing (mean±standard deviation in months) most involved fusion at the level of the outer nuclear layer (ONL) (6.3±10.5) followed by restoration of ELM (9.1±13.8), and lastly, by IS/OS regeneration (13.1±19.5). In severe blunt ocular trauma, healing was fast and involved subretinal zipper glue-like reapposition with resulting outer retinal atrophy. Best spectacle-corrected visual acuity correlated with normalization of the clivus (p=0.012), faster ELM (p=0.006), and IS/OS reconstitution (p=0.024). Recurrence of FTMH occurred when the healing was halted (3 eyes) or was aberrant by lamellar hole epiretinal proliferation (LHEP) (3 eyes) or by the persistence of VMT (1 eye). CONCLUSION: Recovery sequences proceeded from the ONL to the deeper layers with BCVA correlating absolutely and temporally with the restoration of outer retinal layer integrity.

An 18-year-old male high school student presented to our clinic with bilateral blunt ocular trauma caused by an exercise resistance band (ERB) during a muscle-building exercise. Best-corrected decimal visual acuities (BCVAs) for right and left eyes were light perception and 0.15, respectively. The right eye was operated 10 days after injury for persistent vitreous hemorrhage, and the left eye 5 months later because of macular hole onset. After 36 months, the right eye showed extensive retinal degeneration (BCVA 0.04), and the left eye macular hole closure (BCVA 1.2). ERBs should be used cautiously as they can cause serious ocular trauma.

PURPOSE: To investigate the reconstructive changes in foveal microstructures postoperatively and analyze the visual predictors in eyes with surgically closed traumatic macular holes (TMHs). METHODS: Seventy-one eyes with TMHs that underwent vitrectomy, internal limiting membrane (ILM) peeling, and gas tamponade were reviewed. Clinical data, best-corrected visual acuity, and spectral-domain optical coherence tomography (SD-OCT) images were recorded. The length of the ellipsoid zone (EZ) defect and the integrity of postoperative external limiting membrane (ELM) were measured. Preoperative and 1-month postoperative features were analyzed, respectively, as potential predictors of visual acuity at 6 months postoperatively. RESULTS: The primary hole closure rate was 90.14% (64/71). In 43 cases of initially closed TMHs with SD-OCT scans preoperatively and at 1 and 6 months postoperatively, the number of eyes with intact ELM increased from 18 (41.86%) at 1 month to 26 (60.47%) at 6 months (p = 0.08), while the number of eyes with a restored EZ band remained the same in 2 eyes (4.65%). The mean length of the EZ defect progressively decreased postoperatively (p < 0.001). Poorer preoperative visual acuity (p = 0.002), lower mean macular hole (MH) height (p = 0.012), and greater preoperative mean length of EZ defect (p < 0.001) were associated with worse visual acuity 6 months postoperatively, but only the preoperative length of the EZ defect was proved to be a predictor, with the cutoff value of 1,800 µm provided by the receiver-operating characteristics (ROC) curve. Worse visual acuity and greater mean length of the EZ defect at 1 month were also associated with worse final visual acuity. CONCLUSIONS: The mean length of the EZ defect both preoperatively and 1 month postoperatively were predictors of visual outcomes at 6 months postoperatively.

OBJECTIVE: To describe the demographics, clinical, and imaging characteristics, and visual outcomes in young patients with full-thickness traumatic macular hole (TMH). METHODS: This retrospective hospital-based study included patients with full-thickness TMH who presented between August 2010 and June 2021. Demographic data, clinical findings, and imaging characteristics were extracted from an electronic medical record system. Regression analyses were performed to determine significant associations among variables and to identify predictors of visual outcomes. RESULTS: 144 (0.005%) patients among 2,834,616 were diagnosed with Full thickness TMH. The majority of them were male (89.58%; odds ratio [OR] = 6.71) and the holes were unilateral. The mean age at presentation was 23.37 ± 8.19 years. Ball were the most common cause of injuries (22.22%), followed by stick (14.58%) and firecracker (12.50%). The mean LogMAR visual acuity (VA) at presentation was 1.18 ± 0.72, with 25.69% of eyes having VA < 20/400. The mean minimum hole diameter was 619.34 ± 336.16 µm. Sub-retinal fluid was present in 44.44%, followed by intraretinal fluid in 34.03% of eyes. Macular holes closed after vitrectomy in 66.67% of eyes, with mean final VA of 1.07 ± 0.85. Baseline VA was a strong predictor of final VA (R2 = 0.677; p = 0.000168). CONCLUSION: Traumatic macular hole is a unilateral condition with significant visual impairment that is mainly seen in males during the third decade of life. Surgery is successful in most cases but improvements in VA are modest.
RESUMO
A girl of 8 years old was referred to our clinic with a history of penetrating injury to her left eye 6 years ago with light perception vision and a large traumatic macular hole in her right eye. Her right eye's vision was 4/10 when she first visited our clinic. Considering the patient's one-eye status, her parents' reluctance to undergo surgery, and the possibility of spontaneous closure of traumatic macular holes, it was determined to observe the patient and evaluate her visual acuity and macular hole condition. In 2 years, the final best corrected visual acuity was 8/10 in the right eye, with infratemporal eccentric fixation in visuoscopy. In addition to evaluating and reporting this case as a traumatic macular hole, we will discuss the role of nonsurgical treatment and the possibility of good visual acuity with eccentric fixation in a child with large traumatic macular hole.
RESUMO
PURPOSE: To report an accidental case of traumatic macular hole caused by Nd:YAG laser in a dermatology clinic. OBSERVATIONS: A 24-year-old woman sustained a laser injury to her right eye while practicing a dermatologic treatment using a Nd:YAG laser without wearing protective goggles. She noticed sudden-onset and progressing visual loss in her right eye and consulted an ophthalmologist 2 days after injury. The best-corrected visual acuity (BCVA) of her right eye decreased to 20/133. Fundus examination showed white parafoveal flecks with a central retinal hemorrhage and underlying serous retinal detachment. The retinal sensitivity in this lesion deteriorated. Two weeks later, a full-thickness macular hole (FTMH) developed in the affected eye. She was referred to Nagoya City University Hospital where the laser damage described was observed. The BCVA was 20/67. She underwent pars plana vitrectomy performed using the inverted internal limiting membrane (ILM) flap technique and gas tamponade. One week postoperatively, the FTMH closed, the BCVA in her right eye improved to 20/50, and the retinal sensitivity in the macular area mostly improved. The BCVA gradually improved and reached 20/25 9 months after the injury. CONCLUSIONS AND IMPORTANCE: Protective goggles must be worn when using an Nd:YAG laser in the laboratory or clinical setting. In the unfortunate event of a FTMH, early vitrectomy with an inverted ILM flap technique can be helpful to achieve a good visual prognosis.
RESUMO
Objective: This systematic review and meta-analysis aimed to determine the traumatic macular hole (TMH) closure rate and visual acuity (VA) improvement rate by comparing two treatment methods for TMH: vitrectomy and observation for spontaneous closure. Methods: PubMed, Cochrane, Web of Science Library, Embase, CNKI, Wanfang, VIP, and Sino Med were systematically searched from their inception to June 10, 2021. Studies in the surgery group (n = 32) and studies in the observation group (n = 12) were meta-analyzed. The primary outcomes were the TMH closure and VA improvement rates in the surgery and observation groups. The secondary outcomes were best-corrected visual acuity (BCVA) improvement in the surgery group. Stata software (version 15.1) was used for the analyses. Results: Thirty-six studies that included 1,009 eyes were selected for this meta-analysis, among which 33 were retrospective studies and 3 were prospective studies. The meta-analysis showed that the random-model pooled event rate for TMH closure was 0.37 (95% confidence interval [CI], 0.26-0.48) in the observation group, while it was 0.9 (95% CI, 0.85-0.94) in the surgery group. The fixed-model pooled event rate for VA improvement was 0.39 (95% CI, 0.33-0.45) in the observation group, while the random-model pooled event rate of VA improvement for the surgery group was 0.72 (95% CI, 0.63-0.80). The pooled event rate for BCVA improvement in the surgery group was 0.39 (95% CI, 0.33-0.46). Conclusions: This meta-analysis suggests that TMH hole closure and VA improvement rates in the surgery group were significantly higher than those in the observation group. Vitrectomy is an effective method for treating TMH. However, further randomized controlled trials (RCTs) are required to evaluate the efficacy and safety of surgery and observation for TMH treatment.

RESUMO
Purpose: This work aimed to assess postoperative outcomes associated with relaxing parafoveal nasal retinotomy for refractory macular hole repair. Methods: This was a retrospective interventional study of patients with persistent or recurrent macular holes following 1 or more standard repair procedures with pars plana vitrectomy and internal limiting membrane peeling. Patients received an additional pars plana vitrectomy and relaxing parafoveal nasal retinotomy, followed by fluid-air and air-gas exchange. Key postoperative outcomes included the achievement of macular hole closure and changes in visual acuity from baseline. Results: Thirteen patients with refractory macular holes were included, with a median age of 65 years (range, 49-90 years). The aperture diameter of the 13 macular holes ranged from 180 to 799 µm (median, 538 µm). Vitrectomy and relaxing parafoveal nasal retinotomy were performed in all 13 eyes, and after a median follow-up of 12 months (range, 3-34 months), anatomical closure was achieved in 12 of 13 eyes (92.3%). Overall, visual acuity (mean ± SE) improved significantly from 1.20 ± 0.15 logMAR (approximate Snellen equivalent, 20/320) at baseline to 0.84 ± 0.11 logMAR (Snellen, â¼ 20/125) during postoperative follow-up (P < .05). Central and paracentral scotomas were observed in 8 of 11 eyes with postoperative Humphrey visual field 10-2 and/or 24-2 data available. Conclusions: Relaxing parafoveal nasal retinotomy may be an effective method to promote anatomical closure and improve vision outcomes in patients with recalcitrant macular holes.
RESUMO
Complications of closed-globe injury such as submacular hemorrhage (SMH) and traumatic macular hole (TMH) can be visually devastating. It is observed that TMH occurs in 1.4% of closed-globe injuries and 0.15% of open-globe injuries. There is limited data regarding the incidence of TMH with SMH, given its relatively rare occurrence. Treatment options for SMH include vitrectomy with subretinal r-tissue plasminogen activator (TPA)-assisted clot lysis, intravitreal r-TPA-assisted pneumatic displacement using an expansile gas and postoperative positioning, and finally pneumatic displacement alone. We report a unique case of a 26-year-old female with blunt trauma who developed SMH with TMH and breakthrough vitreous hemorrhage. Successful displacement of subretinal blood from the macula and resolution of the macular hole was achieved on day 1 with pneumatic displacement alone using undiluted C3F8 injection.
RESUMO
Various modifications of surgical techniques and surgical adjuncts are adopted with standard pars plana vitrectomy (PPV) to improve the outcome of traumatic macular hole (TMH) surgeries. We describe a successful closure of a chronic large TMH of three years duration with inverted temporal internal limiting membrane (ILM) flap technique. A 36-year-old male patient had an optical coherence tomography (OCT) documented chronic macular hole (MH) for three years following blunt trauma. Fundus examination also showed choroidal rupture scar temporal to fovea. The minimum MH diameter was 769 µ and the basal diameter 1431 µ in OCT. Standard PPV with inverted temporal ILM flap and gas tamponade was done. The postoperative period was uneventful. The best corrected visual acuity improved from 6/60 preoperatively to 6/18 six months postoperatively, and OCT showed a closed MH with anatomical type 1 closure. This case highlights that the inverted temporal ILM flap technique is a safe and effective technique for patients with even chronic and large TMH.
RESUMO
Blunt trauma to the eye can present with protean manifestations involving the anterior and posterior segments of the eye. Giant retinal tear (GRT) following trauma occurs most commonly at the equatorial region or anterior to the equator. GRT posterior to the equator is rare. Herein, we present a case of a 21-year-old male, who presented with sudden diminution of vision in the right eye following blunt-trauma with a cricket ball. Examination revealed a posterior-GRT, full-thickness macular hole, rhegmatogenous retinal detachment, and vitreous hemorrhage in the right eye. He was managed with vitrectomy, encircling scleral band, perfluorocarbon liquid-assisted flattening of GRT, internal limiting membrane peeling, and endotamponade. The probable etiopathogenesis of posterior-GRT and various surgical challenges encountered in this case were also described illustratively in this report.

Objective: To report a case of delayed spontaneous closure of traumatic macular hole at 5 months in a 66-year-old man. Traumatic macular holes generally do not close spontaneously after 4 months and over 30 years of age. Methods: A 66-year-old man presented with central blurred vision and metamorphopsia in his right eye for 3 weeks after previous ocular blunt trauma occurring 2 months earlier. Best corrected visual acuity was 6/36 in his right eye, fundus examination and OCT revealed right traumatic macular hole. Results: 4 weeks later, best corrected visual acuity was 6/18, OCT showed initial reattachment of traumatic macular hole margins. 8 weeks later, best corrected visual acuity improved to 6/9, OCT showed almost complete reattachment of the margins, residual outer retinal defect being still present. At 12 weeks after initial presentation, best corrected visual acuity was 6/6, OCT showed normal neuroretinal profile. Conclusion: Clinical monitoring of traumatic macular holes might be performed up to 5 months even in patients >30 years before considering surgery.
RESUMO
BACKGROUND: Closure of traumatic macular hole (TMH) can be achieved spontaneously or by surgical intervention. Thus far, there exist no prospective comparative studies that have analyzed the difference between the two modalities. This study aimed to compare the anatomical and visual recovery of eyes with TMH following either an immediate vitrectomy or six-month observation. METHODS: This was a multicenter prospective comparative study. Eight centers participated in the study. Patient data from 40 eyes with a recent history of blunt ocular trauma and newly formed full-thickness TMH were recruited in this study. The participating patients selected between an early vitrectomy or a six-month observation after a doctor explained the potential benefits and risks of both strategies in an unbiased manner. Twenty-five patients underwent an immediate vitrectomy, and 15 patients received six-month observation. Patients were assessed by spectral-domain optical coherence tomography (SD-OCT) and best-corrected visual acuity (BCVA). RESULTS: Closure rates were 66.7% for the observational group, and 100% for the surgical group (P=0.002). There were no vision-threatening ocular complications in both groups. For the observational group, the mean closure time was 2.5±1.6 months, and 80% of the hole closure occurred within 3 months; cystic edema on the edge of the hole at baseline was significantly more frequent in the non-closed subgroup than in the closed subgroup (P=0.03). There were no significant differences in the foveal microstructure and in the final visual outcome between the spontaneously closed cases and the surgically closed cases. CONCLUSIONS: TMH had a moderately high incidence of spontaneous closure, but an immediate vitrectomy achieved an even higher closure rate. Vitrectomy was effective and safe to treat TMH, while a 3-month observation for spontaneous closure may be an alternative modality for TMH management. Cystic edema on the edge of the hole may be an unfavorable factor for the spontaneous closure of TMH.
RESUMO
A 7-year-old boy presented with history of blunt trauma 1 month back. Best corrected visual acuity (BCVA) was 20/200 with optical coherence tomography (OCT) showing a large macular hole. Spontaneous closure of the macular hole seemed unlikely following a month of observation. Pars plana vitrectomy along with autologous retinal graft was performed. At subsequent follow up, hole appeared closed with nasal shrinkage of graft and BCVA improved to 20/100. OCT showed mechanical integration of the graft with adjoining retina. Autologous retinal graft is a feasible option in cases where conventional internal limiting membrane peeling shows lower anatomical success.

PURPOSE: To report the visual result of Surgery for traumatic macular hole with choroidal rupture running across papillomacular bundle. METHOD: Observation case report Patient 20 year old male patient presented with acute vison loss in OS with BCVA reduced to 20/80 following blunt trauma. Examination revealed full thickness macular hole with choroidal rupture between disc and macula, spanning across papillomacular bundle (PMB) in OS. Patient underwent 25G Vitreous Surgery with ILM peeling and SF6 injection for OS. RESULTS: Macular hole was successfully closed at 4 weeks follow up and BCVA improved to 20/20. There was no postoperative complication. CONCLUSION: We report that Traumatic macular holes with associated choroidal rupture running through PMB can be successfully repaired with Vitreous surgery and these eyes may achieve good visual outcome.
RESUMO
Large traumatic macular holes (TMHs) tend to be irregular and have a variable predictability. The inverted flap technique makes use of remnants of internal limiting membrane (ILM) at the periphery of the MH. The peeled-off ILM contains Müller cell fragments which can induce gliosis and help in closure of MH. We operated on a case of large TMH (~899 µ minimum linear diameter) with choroidal rupture and subretinal hemorrhage in a young female with the inverted flap technique of ILM peeling and observed successful closure of the MH. The excellent anatomical and surgical results achieved in our case seem to suggest this to be a safe and effective surgical manoeuvre for such cases.
RESUMO
·AIM: To observe the application of optical coherence tomography ( OCT ) in the diseases of traumatic macular hole.·METHODS: Twenty - five eyes of 23 patients with traumatic macular hole from January 2015 to January 2017 were enrolled in this study, including 9 eyes treated without surgeries, 16 eyes with surgeries. The image features were analyzed using OCT from ZEISS.·RESULTS: The OCT characteristics in patients with traumatic macular hole were partial or full - thickness disappearance of the neuro-epithelium. Posterior vitreous detachment was not seen in the traumatic macular hole. OCT examination revealed that 4 eyes had partial detachment of macular hole and 21 eyes had full thickness detachment. Of the twenty-one eyes, 4 eyes had simple macular hole, 10 eyes had macular full-layer division with peripheral nerve epithelium edema, 7 eyes had the macular full - layer hole with the neuro - epithelium localized detachment. In the 25 eyes, 9 eyes did not undergo the surgery, of which 7 eyes were self-healing;16 eyes were surgically treated. Postoperative OCT showed the macular structure were normal in 12 eyes with the visual acuity improved 3 lines; retinal nerve epithelium were thinning in 4 eyes, visual acuities were not significant improved after surgery.·CONCLUSION: OCT examination is necessary for the diagnosis and treatment of traumatic macular hole.
RESUMO
Macular hole formation is a well-known complication following ocular trauma. Less commonly recognised is the spontaneous closure of such holes. A 27-year-old man presented with a history of blunt trauma to his left eye. Eye evaluation showed conjunctival laceration, diffuse retinal oedema and multiple retinal haemorrhages in that eye. A month later, he developed a full thickness macular hole. Two months later, there was spontaneous complete closure of the full-thickness macular hole in the left eye as confirmed on optical coherence tomography. Spontaneous closure of hole is not uncommon. Observation for a period of up to 12 months is a reasonable management option. Macular hole surgery for traumatic macular holes may be delayed in such cases.
