Abstract
This study examined the effect of vitrectomy combined with internal limiting membrane (ILM) peeling on foveal displacement in 42 eyes with idiopathic macular hole (IMH). A retrospective analysis was conducted to measure various macular hole parameters before surgery, including basal diameter, minimum diameter, hole height, and areas affected by traction such as macular hole area (MHA), macular hole cystoid space area (MHCSA), macular hole retinal area (MHRA), and total area (TA). The results showed a postoperative shift of the fovea towards the optic disc in all cases. Notably, the extent of foveal displacement was significantly linked to the preoperative basal diameter (rs = 0.405, P = 0.008) but not to other preoperative parameters or postoperative visual acuity. Furthermore, the study found that the temporal side of the macular hole was more affected by traction than the nasal side preoperatively, leading to greater postoperative displacement (All P < 0.05).

Abstract
Age-related changes in vitreous molecular and anatomic morphology begin early in life and involve two major processes: vitreous liquefaction and weakening of vitreo-retinal adhesion. An imbalance in these two processes results in anomalous posterior vitreous detachment (PVD), which comprises, among other conditions, vitreo-macular adhesion (VMA) and traction (VMT). VMA is more common in patients with neovascular age-related macular degeneration (nAMD) than age-matched control patients, with the site of posterior vitreous adherence to the inner retina correlating with location of neovascular complexes. The pernicious effects of an attached posterior vitreous on age-related macular degeneration (AMD) progression involve mechanical forces, enhanced fluid influx and inflammation in and between the retinal layers, hypoxia leading to an accumulation of vascular endothelial growth factor (VEGF) and other stimulatory cytokines, and probably an infiltration of hyalocytes. It has been shown that vitrectomy not only mitigates progression to end-stage AMD, but existing choroidal neovascularization regresses after surgery. Thus, surgical PVD induction during vitrectomy or by pharmacologic vitreolysis may be considered in non-responders to anti-VEGF treatment with concomitant VMA.

Abstract
PURPOSE To report contributory factors and clinical outcomes of central posterior hyaloid fibrosis (CPHF) associated with neovascular age-related macular degeneration (nAMD). METHODS In this retrospective, single-center study, patients with CPHF and nAMD were included. Demographic and imaging characteristics, as well as the anatomical and functional outcomes, of these patients were analysed. RESULTS We identified 530 eyes in 273 patients with chronic predominantly scarred macular neovascularisation (MNV), and 32 eyes in 29 patients revealed CPHF, representing a prevalence of 6%. Patients had a mean age of 72.76 years. Before and during the development of CPHF, Type 2 MNV was observed in all eyes. At the time of MNV diagnosis, mean logMAR visual acuity was 1.308 ± 0.559 (20/407). The average time to develop CPHF was 27.3 months since the diagnosis of MNV. At the time of CPHF identification, the mean logMAR visual acuity was 1.498 ± 0.374 (20/630). RPE tear was observed in 6% (n = 2) of CPHF eyes. The average number of intravitreal anti-VEGF injections administered prior to the diagnosis of CPHF was 2.4 and after the onset of CPHF was 0.9. The final visual acuity was not significantly different at the final follow-up visit [1.304 ± 0.42 (20/402); p = 0.646]. CONCLUSION Rarely observed in eyes with predominantly scarred subfoveal type 2 MNVs and extensive subretinal fibrosis, CPHF is associated with poor visual outcomes. Its presence could possibly suggest a profibrotic effect of MNV on the posterior hyaloid. TRIAL REGISTRATION NUMBER Not applicable.

Abstract
BACKGROUNDS To measure the degree of curvature of the retinal artery trajectory (RAT) and retinal vein trajectory (RVT) in the eyes of patients with vitreomacular traction (VMT) and compare them with their healthy fellow eyes. METHODS This was a retrospective, cross-sectional, case-control study of 58 eyes of 29 patients with unilateral VMT. The participants were divided into two groups. Group 1 VMT was defined as having only morphological changes, while group 2 VMT was defined as morphological changes accompanied by the presence of a cyst or hole to quantify the severity of the disease. The RATs and RVTs were assessed from the color fundus photographs using the ImageJ program. The fundus photographs were rotated 90 degrees. The course of the retinal arteries and veins were marked on a color fundus photograph and fitted to a second-degree polynomial curve (ax[x]/100+bx+c). The coefficient ''a'' was the width and steepness of the trajectories. The comparison between the RAT and RVT of vitreomacular traction and healthy fellow eyes was investigated and the association between the RAT and RVT and the severity of disease were determined using the Image J program. RESULTS Eleven subjects were male, and 18 subjects were female. The mean ± SD age was 70.6 ± 7.6 years. Eighteen of the eyes had VMT in the right and 11 of the eyes had VMT in the left eye. Eleven eyes were in group 1 and 18 eyes were in group 2. Axial length (AL) was similar between the two groups (22.63 ± 1.20 mm vs 22.45 ± 1.45 mm p=0.83). (Table 1) The mean RAT was 0.60±0.18 in eyes with VMT and 0.51±0.17in healthy eyes (p=0.063). The mean RVT was 0.74±0.24 in eyes with VMT and 0.62±0.25 in healthy eyes for the whole group (p=0.02). In group 1, the mean RVT of the eyes with VMT was statistically significantly higher than the healthy eyes (p=0.014). There was not any statistically significant difference for the other parameters evaluated between eyes with VMT and healthy eyes according to the groups and the whole group. (Table 2-3-4) CONCLUSION: Unlike other vitreoretinal interface diseases such as epiretinal membrane and macular hole, VMT may be characterized by a narrower RVT, which is characterized by a larger "a" value.

Abstract
CLINICAL RELEVANCE Vitreomacular traction(VMT) is a clinical syndrome that can cause decreased vision and may affect the treatment response in cases of age-related macular degeneration(AMD). Factors affecting the course of VMT in AMD cases will guide the clinician in terms of patient management. BACKGROUND The aim of this study was to determine the prevalence of VMT in patients with AMD, to evaluate the natural course of VMT, and to investigate factors associated with the prognosis of VMT in eyes with AMD. METHODS This retrospective case series was conducted with 55 eyes of 46 patients who were diagnosed as having AMD accompanying with VMT. Demographic data, complete ophthalmologic examination findings, type of AMD, receiving an intravitreal injection(IVI), number of IVIs, and the presence of complete spontaneous release were obtained from the medical records of the patients. The horizontal length of VMT(HLVMT), central macular thickness(CMT), the horizontal length of choroidal neovascularization(HLCNV) were evaluated from spectral-domain optical coherence tomography(SD-OCT) images. RESULTS Spontaneous release was observed in 7(28%) eyes of the exudative AMD group and 10(33.3%) eyes of the nonexudative AMD group. On the last visit, the HLVMT was increased in 22(40%) of the eyes and a decrease in HLVMT was observed in 8(14.5%) of the eyes. In the remaining 12(21.8%) eyes had unchanged HLVMT. In all eyes with CNV, the area of VMT corresponded in 100% with localization of the CNV complex. No significant difference was found between the eyes with spontaneous release and persistent traction in terms of the type of AMD, IVI, HLVMT, age, gender, and crystalline lens status. CONCLUSION In this study, VMT was observed at higher rates in eyes with exudative AMD compared to the eyes with nonexudative AMD. However, spontaneous release rates were found close to those with idiopathic VMT independently of the type of AMD, HLVMT, and IVI.

Abstract
Purpose To explore the prevalence and associations of vitreous macular traction (VMT) in Chinese population. Methods A population-based cross-sectional study with 3468 individuals (mean age of 64.6 ± 9.8 years) based on Beijing Eye Study 2011. Participants underwent detailed ophthalmic examinations, including spectral domain optical coherence tomography (SD-OCT). VMT was defined as abnormal posterior vitreous detachment with anatomical deformation of the fovea, which may include pseudocyst, macular schisis, cystoid macular edema, and subretinal fluid. Main Outcome Measure Prevalence of VMT. Results A VMT was detected in 151 (2.3%) eyes (prevalence rate (mean ± SE): 2.3± 0.2%; 95% CI: 1.9%, 2.7%) of 80 (2.4%) subjects (prevalence rate: 2.4± 0.3%; 95% CI: 1.9%, 2.9%). Mean age of all subjects with VMT was 70.1± 8.7 years (median, 70.0 years; range, 50–90 years), mean refractive error was −0.22 ± 2.38D (median, 0.25 D; range, −15.00 to 5.25D). In multivariate analysis, prevalence of VMT was associated with elder age (P=0.001, OR 1.06), female gender (P = 0.036, OR 1.77), subfoveal retinal thickness (P = 0.005, OR 1.01), and subfoveal choroidal thickness (P = 0.026, OR 0.10). Conclusion In adult Chinese in Greater Beijing, the prevalence of VMT was 2.3% for eyes or 2.4% for subjects. While it was associated with elder age, female gender, thicker subfoveal retinal thickness and thinner subfoveal choroidal thickness.

Abstract
Purpose To describe the prevalence, risk factors, and associations of vitreoretinal interface (VRI) abnormalities in a population-based study of older adults. Design Cross-sectional analysis of cohort study participants. Participants Of the 1149 participants (mean age, 76.1 ± 6.9 years) in the 15-year Blue Mountains Eye Study follow-up examination from 2007 through 2009, 905 (1791 eyes) had gradable time-domain or spectral-domain OCT scans of the macula from at least 1 eye. Methods OCT scans were graded according to the International Vitreomacular Traction Study Group classification system of VRI abnormalities. Best-corrected visual acuity (BCVA) was recorded. Main Outcome Measures Prevalence of VRIs. Results Overall, 451 participants showed any VRI abnormality (49.8%). Prevalence of VRI abnormality by person was: vitreomacular adhesion (VMA), 33.6%; vitreomacular traction (VMT), 1.6%; epiretinal membrane (ERM), 21.4%; full-thickness macular hole (FTMH), 0.7%; and lamellar macular hole (LMH), 0.7%. Twenty-two percent of VMAs were focal, and 78% were broad based; 76% of VMTs were focal, and 24% were broad based. All FTMHs observed were large (>400 μm), with mean aperture size of 573 μm (range, 459–771 μm). Increased age was associated with higher ERM and lower VMA prevalence (P < 0.001 for both). Pseudophakia and myopia were associated with ERM (age- and sex-adjusted odds ratios [ORs], 1.48 [95% confidence interval (CI), 1.01–2.17] and 1.72 [95% CI, 1.05–2.81], respectively). Moderate or severe ERM and FTMH were associated with worse BCVA of 9.2 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (95% CI, 3.4–15.0 ETDRS letters; P = 0.008) and 26.0 ETDRS letters (95% CI, 10.9–41.1 ETDRS letters; P = 0.001), respectively. Conclusions The prevalence of VRI abnormalities is high in older individuals. Epiretinal membrane was associated with increasing age, pseudophakia, and myopia. Epiretinal membrane and FTMH may account for significant visual loss in the affected eye. This study provided useful population-based data on the prevalence of VRI abnormalities in older individuals.

Correlations between intraretinal cystoid cavities and pre- and postoperative characteristics of eyes after closure of idiopathic macular hole. Sci Rep 2020; 10:2310. [PMID: 32047222 PMCID: PMC7012932 DOI: 10.1038/s41598-020-59295-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Accepted: 01/28/2020] [Indexed: 11/08/2022] Open
Abstract
Intraretinal cystoid cavities have been detected at the edges of macular holes (MHs) but their clinical characteristics and their relationship to the MH variables have not been determined. We measured the areas of the intraretinal cystoid cavity in 111 eyes with MHs in the OCT images preoperatively. Our results showed that the intraretinal cystoid cavities were located in the Henle fiber layer-outer nuclear layer (HFL-ONL) complex in 106 eyes and in the inner nuclear layer (INL) in 89 eyes. All were resolved after the initial vitrectomy to close the MH. The mean area of the cystoid cavity was greater in the HFL-ONL complex (55.9 ± 42.7 × 103 μm2) than in the INL (9.1 ± 9.8 × 103 μm2; P < 0.001). The area of the cystoid cavities was significantly correlated with the basal MH size (r = 0.465,P < 0.001), the external limiting membrane height (r = 0.793, P < 0.001), and the maximum retinal thickness (r = 0.757, P < 0.001). The area of the cystoid cavities was significantly correlated with the preoperative best-corrected visual acuity (BCVA; r = 0.361, P < 0.001), but not with the postoperative BCVA or the integrity of any of the outer retinal microstructural bands. The presence of intraretinal cystoid cavities was related to some morphological characteristics, but not to the postoperative BCVA or the restoration of the outer retinal bands.

Abstract
PURPOSE To test the hypothesis that refractive errors such as myopia and hyperopia cause an increased risk of age-related macular degeneration (AMD) and to quantify the degree of risk. DESIGN Two-sample Mendelian randomization analysis of data from a genome-wide association study. PARTICIPANTS As instrumental variables for refractive error, 126 genome-wide significant genetic variants identified by the Consortium for Refractive Error and Myopia and 23andMe Inc. were chosen. The association with refractive error for the 126 variants was obtained from a published study for a sample of 95,505 European ancestry participants from UK Biobank. Association with AMD for the 126 genetic variants was determined from a genome-wide association study (GWAS) published by the International Age-related Macular Degeneration Genomics consortium of 33,526 (16,144 cases and 17,832 controls) European ancestry participants. METHODS Two-sample Mendelian randomization (MR) analysis was used to assess the causal role of refractive error on AMD risk, using the 126 genetic variants associated with refractive error as instrumental variables, under the assumption that the relationship between refractive error and AMD risk is linear. MAIN OUTCOME MEASUREMENT the risk AMD was caused by a 1-diopter (D) change in refractive error. RESULTS MR analysis suggested that refractive error had very limited influence on the risk of AMD. Specifically, 1 D more hyperopic refractive error was associated with an odds ratio (OR) of 1.080 (95% confidence interval [CI], 1.021-1.142; P = 0.007) increased risk of AMD. MR-Egger, MR pleiotropy residual sum and outlier, weighted median, and Phenoscanner-based sensitivity analyses detected minimal evidence to suggest that this result was biased by horizontal pleiotropy. CONCLUSIONS Under the assumption of a linear relationship between refractive error and the risk of AMD, myopia and hyperopia only minimally influence the causal risk for AMD. Thus, inconsistently reported strong associations between refractive error and AMD are likely to be the result of noncausal factors such as stochastic variation, confounding, or selection bias.

Abstract
AIM To determine whether intravitreal dexamethasone (DEX) implant induces posterior vitreous detachment or not. METHODS We retrospectively reviewed 810 eyes of 405 patients who underwent intravitreal DEX implantation due to macular edema caused by diabetic and retinal venous occlusion in our clinic. The eyes having no injection were determined as the control group. The examination findings of the patients before the injection and 3mo after the injection and optical coherence tomography (OCT) images were scanned. The pre-injection OCT findings and OCT findings of the patients having no posterior vitreous detachment (PVD) and determined to have partial PVD were compared. RESULTS The separation in vitreoretinal adhesion and total PVD development of DEX-injected 56/208 (26.9%) eyes were statistically greater in comparison with the 12/129 (9.3%) eyes that had not been injected (P=0.001). PVD development was observed more in the patients that were younger, had larger macula thickness and lower visual acuity. CONCLUSION It can be stated that intravitreal DEX implant induces PVD development. Prospective, controlled studies are required in order to determine prognosis of vitreoretinal disease in PVD-developed patients and in non-PVD-developed patients.

Abstract
Symptomatic vitreomacular adhesion (sVMA) is defined as visual loss secondary to foveal damage from vitreomacular traction (VMT) and includes isolated VMT, impending macular hole (MH), and full-thickness MH with persisting vitreous attachment. Management options include pars plana vitrectomy (PPV), intravitreal ocriplasmin, intravitreal gas injection or observation. This synthesis of the literature aimed to assess the safety and efficacy of intravitreal gas for sVMA. Articles describing patients with VMT or MH treated with intravitreal expansile gas were selected by systematic literature review using MEDLINE, EMBASE, and the Cochrane Database of Controlled Trials (CENTRAL) up to September 2016. The main outcomes at 1 month and final review were logarithm of the minimum angle of resolution (logMAR) visual acuity (VA), anatomical success (absence of both VMT and MH, without PPV) and adverse events (AEs). The intended comparator was observation. Nine of 106 identified articles were eligible, and none were randomized controlled trials. The mean VA of 91 eyes improved from 0.55 (Snellen equivalent 6/21) to 0.48 (6/18) logMAR at 1 month and to 0.35 (6/13) logMAR at final review. The mean VA at final review, prior to a vitrectomy, was 0.42 (6/16). Anatomic success was 48% at 1 month and 57% at final review. The reported AEs comprised retinal detachment in two highly myopic eyes. Intravitreal gas injection can relieve sVMA. Larger controlled studies are needed to determine safety and efficacy relative to observation, ocriplasmin, or vitrectomy.

Abstract
PURPOSE To assess the effect of an intravitreal ocriplasmin injection on visual function, measured using visual acuity (VA) and vision-related quality of life. METHODS Post hoc analysis of prespecified secondary end-points in two multicentre, randomized, double-masked, phase 3 clinical trials. A total of 652 participants with symptomatic vitreomacular adhesion were enrolled, of whom 464 received a single intravitreal injection of 125 μg ocriplasmin and 188 received a single intravitreal placebo injection. Based on principal components analysis results, visual function response (VFR) was defined as either a VA improvement of ≥2 lines; or an improvement in the composite score of the National Eye Institute Visual Function Questionnaire (VFQ-25) exceeding the minimal clinically important difference (MCID), estimated using the standard error of measurement approach; or an improvement in the VFQ-25 driving subscale score exceeding the MCID. The main outcome measure was VFR at 6 months. RESULTS A VFR occurred in 55.1% of the ocriplasmin group versus 34.2% of the placebo injection group (p < 0.0001). This comprised 23.7% versus 11.2% (p = 0.0003) with a ≥ 2-line VA improvement, 35.9% versus 22.7% (p = 0.0016) for the VFQ-25 composite score, and 10.2% versus 6.2% (p = 0.1697) for the driving subscale. CONCLUSION Ocriplasmin produces a clinically meaningful visual function benefit.

Abstract
The aim of the study was to evaluate the influence of vitreomacular interface configuration on treatment outcomes after intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (AMD).The Pubmed, Embase, and Cochrane Central Register of Controlled Trials databases were searched to identify relevant prospective or retrospective studies that evaluate the influence of vitreomacular adhesion (VMA) or vitreomacular traction (VMT) on functional and anatomical outcomes in neovascular AMD patients treated with anti-VEGF agents. The outcome measures were the mean change in best corrected visual acuity (BCVA) from baseline, the mean change in central macular thickness (CMT) from baseline, and the mean injection numbers of anti-VEGF treatment from baseline.In total, 9 studies were selected for this meta-analysis, including 2156 eyes (404 eyes in the VMA/VMT group and 1752 eyes in the non-VMA/VMT group). In neovascular AMD patients treated with anti-VEGF agents, the VMA/VMT group was associated with poorer visual acuity gains and CMT reductions at 1 year (WMD [95% CI], -6.17 [-11.91, -0.43] early treatment diabetic retinopathy study (ETDRS) letters, P = .04; WMD [95% CI], 22.19 [2.01, 42.38] μm, P = .03, respectively). There was no significant difference between 2 groups in the mean BCVA change and the CMT change over 2 years (WMD [95% CI], -5.59 [-21.19, 10.01] ETDRS letters, P = .48; WMD [95% CI], 6.56 [-24.78, 37.90] μm, P = .68, respectively). There was no significant difference in the mean injection numbers between 2 groups at 1 year (WMD [95% CI], 0.36 [-0.19, 0.90], P = .21), whereas the VMA/VMT group had a significantly higher mean injection numbers over 2 years (WMD [95% CI], 1.14 [0.11, 2.16], P = .03).The limited evidence suggests that vitreomacular interface configuration have a significant influence on the visual acuity gain and CMT reduction at 1 year, injection numbers at 2 years in neovascular AMD patients treated with anti-VEGF agents. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity among study designs. Eyes with VMA/VMT on optical coherence tomography at baseline may require more intensive treatment with decreased response to anti-VEGF agents.

Abstract
BACKGROUND Symptomatic vitreomacular adhesion (sVMA) is a recognised cause of visual loss and by tradition has been managed by pars plana vitrectomy (PPV). A less invasive alternative to surgery in some people is enzymatic vitreolysis, using an intravitreal injection of ocriplasmin. OBJECTIVES To assess the efficacy and safety of ocriplasmin compared to no treatment, sham or placebo for the treatment of sVMA. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 1), MEDLINE Ovid (1946 to 24 February 2017), Embase Ovid (1947 to 24 February 2017), PubMed (1946 to 24 February 2017), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 24 February 2017, ClinicalTrials.gov (www.clinicaltrials.gov); searched 24 February 2017 and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 24 February 2017. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) of people with sVMA. The intervention was intravitreal ocriplasmin 125 μg injection, and this was compared to placebo or sham injection (control). Placebo was defined as a single intravitreal injection of 0.10 mL placebo with identical drug vehicle diluted with saline. A sham injection was defined as the syringe hub or blunt needle touching the conjunctiva to simulate an injection. DATA COLLECTION AND ANALYSIS Two authors independently selected relevant trials, assessed methodological quality and extracted data. We graded the certainty of the evidence using the GRADE approach. MAIN RESULTS This review included four RCTs conducted in Europe and the USA with a total of 932 eyes of 932 participants. Participants were 18 to 97 years of age, with evidence of focal vitreomacular adhesion (VMA) on optical coherence tomography (OCT) imaging, with a best corrected visual acuity (BCVA) of 20/25 or worse in the study eye and 20/400 or better in the fellow eye. The interventions compared were intravitreal ocriplasmin versus sham (two RCTs) or placebo (two RCTs) injection. Both sham and placebo injection were classified as the control group. The main outcome measures were assessed at 28 days and six months. Overall, we judged the studies to have a low or unclear risk of bias. All four RCTs were sponsored by the manufacturers of ocriplasmin.Compared with control, ocriplasmin treatment was more likely to result in VMA release within 28 days (risk ratio (RR) 3.46, 95% confidence interval (CI) 2.00 to 6.00; 859 eyes, 4 RCTs, high-certainty evidence). Approximately 97/1000 eyes will have VMA release within 28 days without treatment. An additional 237 eyes will have VMA release within 28 days for every 1000 eyes treated with ocriplasmin (95% CI 96 more to 482 more).Treatment with ocriplasmin was also more likely to result in macular hole closure (RR 2.87, 95% CI 1.50 to 5.51; 229 eyes, 3 RCTs, high-certainty evidence). Approximately 123/1000 eyes with macular holes will have closure with no treatment. An additional 231 eyes will have macular hole closure for every 1000 eyes treated with ocriplasmin (95% CI 62 more to 556 more).Eyes receiving ocriplasmin were also more likely to have complete posterior vitreous detachment (PVD) within 28 days (RR 2.94, 95% CI 1.39 to 6.24; 689 eyes, 3 RCTs, high-certainty evidence). Approximately 40/1000 eyes will have complete PVD within 28 days without treatment. An additional 78 eyes will have complete PVD within 28 days for every 1000 eyes treated with ocriplasmin (95% CI 16 more to 210 more).Eyes receiving ocriplasmin were more likely to achieve 3-line or greater improvement in BCVA at six months (RR 1.95, 95% CI 1.07 to 3.53; 674 eyes, 3 RCTs, moderate-certainty evidence). Approximately 61/1000 eyes will have a 3-line or greater improvement in BCVA at six months without treatment. An additional 58 eyes will have 3-line or greater improvement in BCVA at six months for every 1000 eyes treated with ocriplasmin (95% CI 9 more to 154 more).Receiving ocriplasmin also reduced the requirement for vitrectomy at six months (RR 0.67, 95% CI 0.50 to 0.91; 689 eyes, 3 RCTs, moderate-certainty evidence). Approximately 265/1000 eyes will require vitrectomy at six months without treatment and 87 fewer eyes will require vitrectomy for every 1000 eyes treated with ocriplasmin (95% CI 24 fewer to 132 fewer).Treatment with ocriplasmin resulted in a greater improvement in validated Visual Function Questionnaire form score at six months (mean improvement difference 2.7 points, 95% CI 0.8 to 4.6; 652 eyes, 2 RCTs, moderate-certainty evidence).Eyes receiving ocriplasmin were more likely to have an adverse event (RR 1.22, 95% CI 1.09 to 1.37, 909 eyes, 4 RCTs, moderate-certainty evidence). Approximately 571/1000 eyes will have an adverse event with sham or placebo injection and 106 more eyes will have an adverse event for every 1000 eyes treated with ocriplasmin (95% CI 52 more to 212 more). AUTHORS' CONCLUSIONS Evidence from a limited number of RCTs suggests that ocriplasmin is useful in the treatment of sVMA. However, up to 20% of eyes treated with ocriplasmin will still require additional treatment with PPV within six months. There were more ocular adverse events in eyes treated with ocriplasmin than control (sham or placebo injection) treatment. Many of these adverse events, particularly vitreous floaters and photopsia, are known to be associated with posterior vitreous detachment. At present however, there is minimal published long-term safety data on eyes treated with ocriplasmin. Further large RCTs comparing ocriplasmin with other management options for sVMA would be beneficial.

Abstract
PURPOSE To compare choroidal thickness after vitrectomy between epiretinal membrane (ERM) with and without vitreomacular traction (VMT). METHODS In this retrospective study, 228 consecutive participants with ERM who underwent vitrectomy were categorized into two groups according to the presence of VMT on spectral domain-optical coherence tomography: VMT group (ERM with VMT, n = 21) and non-VMT group (ERM without VMT, n = 207). The primary outcome was the mean subfoveal choroidal thickness (SFCT) at baseline, and at 3 and 6 months postsurgery. RESULTS At baseline, the prevalence of VMT in eyes with ERM was 9.6% (21/228), and mean SFCT was greater in the VMT than in the non-VMT group (270.3 ± 93.4 vs. 223.7 ± 82.1 μm; p = 0.015). After surgery, mean SFCT decreased in the VMT group (241.7 ± 92.3 μm at 3 months and 228.8 ± 86.4 μm at 6 months; p < 0.001), but remained unchanged in the non-VMT group (223.6 ± 78.9 μm at 3 months and 223.3 ± 82.6 μm at 6 months; p = 0.696). There were no differences in mean SFCT between the groups at 3 and 6 months after surgery (p = 0.339 and p = 0.772, respectively). CONCLUSION Choroidal thickness was greater in ERM eyes with than without VMT possibly due to direct anteroposterior traction on the retina and choroid, increased vascular endothelial growth factor associated with stress on retinal pigment epithelial cells and inflammation. After vitrectomy, mean SFCT reduced in the eyes with VMT, but not in those without VMT.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to assess the prevalence of posterior vitreous detachment (PVD) and vitreoretinal interface in patients with age-related macular degeneration (AMD). PATIENTS AND METHODS This clinical trial included 206 eyes of 138 patients who presented to the authors' clinic between January 2012 and November 2014. Patients were divided into three groups: 98 eyes of 67 patients with exudative AMD, 55 eyes of 36 patients with nonexudative AMD, and 53 eyes of 35 patients having no vitreoretinal disease. All patients underwent complete ocular examination, including best-corrected visual acuity, Goldmann applanation tonometry, fundus photography, spectral-domain optical coherence tomography, and B-mode ultrasonography at 6 months and 12 months after the initial examination. RESULTS Total and partial PVD rates were significantly higher at baseline, 6 months, and 12 months in both exudative and nonexudative AMD groups when compared to the control group (Chi-square test, P = .006, P = .001, and P = .009, respectively). The prevalence of total PVD was significantly higher in nonexudative AMD, whereas partial PVD was higher in exudative AMD. The exudative AMD group reported significantly more VMA than the other two groups at baseline, 6 months, and 12 months (Chi-square test, P =.005, P = .003, and P = .019, respectively). CONCLUSION This study indicates that the incidence of vitreoretinal interface abnormalities such as partial PVD and vitreomacular adhesion were higher in the exudative AMD group. It can be concluded that abnormal adhesive and tractional forces due to PVD may play a role in the progression of AMD. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:223-229.].

Abstract
OBJECTIVE The aim of this review is to determine whether vitreomacular adhesion (VMA) or vitreomacular traction (VMT) has an influence on the outcomes of antivascular endothelium growth factor (anti-VEGF) treatment neovascular age-related macular degeneration (nAMD). METHODS A systematic literature search was performed in Pubmed.gov, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang, SinoMed and ClinicalTrials.gov up to 30 June 2016 to identify eligible studies. RESULTS Nine studies and 2212 participants were finally identified. At month 6, the mean improvement in best-corrected visual acuity (BCVA) and mean decline in central retinal thickness (CRT) of the VMA/VMT(+) group was less than that of the VMA/VMT(-) group (95% CI -3.05 to -0.96 letters, p=0.0002; 15.53 to 32.98 μm, p<0.00001; respectively); at month 12, there was a small or only marginally significant difference (-0.01 to 2.00 letters, p=0.05; 0.17 to 23.7 μm, p=0.05; respectively) between the groups. During the 12 months, however, the VMA/VMT(+) group required more injections ((0.25 to 0.95), p=0.0008). CONCLUSIONS In using anti-VEGF drugs to treat nAMD, clinicians should take into account the fact that concurrent VMA or VMT might antagonise the efficacy of anti-VEGF drugs during the early stage of treatment.

Abstract
PURPOSE To assess the prevalence of vitreoretinal interface abnormalities in a general population of healthy adults ≥45 years of age. DESIGN Cross-sectional study carried out at 17 ophthalmology services throughout Spain. PARTICIPANTS Between September 2015 and March 2016, all consecutive healthy persons aged ≥45 years who were accompanying patients to ophthalmology services were invited to take part in the study. Exclusion criteria were known retinal disease, uveitis, history of ocular trauma or previous intraocular surgery (including cataract surgery and intravitreal injections), severe myopia (>-6 dioptres), and poor ocular media transparency. METHODS Spectral-domain OCT or swept-source OCT was performed on all participants. Diseases of the vitreomacular interface were classified according to the OCT-based anatomic classification system of the International Vitreomacular Traction Study Group. All pathologic and borderline images as well as doubtful cases were evaluated blindly in a central reading center. MAIN OUTCOME MEASURES Prevalence of vitreomacular interface abnormalities (vitreomacular traction epiretinal membrane, lamellar hole). RESULTS The study included 2257 participants with a mean age of 59.5 years (range 45-90), and a total of 4490 eyes (right eyes 2242, left eyes 2248). Vitreoretinal interface abnormalities were detected in 70 eyes, with a prevalence of 1.6%. Vitreomacular adhesion was observed in 1317 eyes (29.3%). Results of spectral-domain OCT or swept-source OCT examination were unrevealing in 3103 eyes. Vitreoretinal interface abnormalities were found in 61 participants, with a prevalence in the study population of 2.7%. Vitreomacular traction was observed in 14 participants (0.6%), epiretinal membrane in 44 (1.9%), and lamellar macular hole in 3 (0.1%). The prevalence of both vitreomacular traction and epiretinal membrane increased significantly with age. The presence of vitreoretinal interface abnormalities was unrelated to concomitant diabetes mellitus or hypertension. CONCLUSIONS An important percentage of healthy participants from the general population ≥45 years of age showed vitreoretinal interface abnormalities. Screening with OCT is advisable at any first routine consultation or preoperative assessment, particularly in older participants.

Abstract
PURPOSE To study the effects of repeated intravitreal injection of anti-VEGF drug bevacizumab on the vitreoretinal interface (VRI). METHODS Patients undergoing intravitreal injection of bevacizumab were enrolled. Eyes with media haze, uveitis, high myopia, history of cataract surgery or laser capsulotomy in last 6 months and complicated pseudophakia were excluded. VRI evaluation was done monthly for a minimum of 6 months. The nature and timing of the change(s) event was recorded. RESULTS A total of 100 eyes were evaluated. Thirty-seven eyes developed new vitreoretinal interface change event (VICE). Pseudophakia (OR = 5.23, 95% CI = 1.99-14.07, p = 0.001), pre-injection VRI abnormality (OR = 2.63, 95% CI = 1.13-6.14, p = 0.024) and older age at enrollment (62.6 ± 13.9 vs. 56.3 ± 14 years) were risk factors for development of VICE. Eighty percent of interface events occurred in the first 3 months of therapy. Eight needed surgical intervention for consequences of vitreoretinal separation. CONCLUSION VICE is not infrequent in eyes receiving anti-VEGF therapy though rarely need surgical intervention. The first 3 months are the critical months to watch out for these events. The treating ophthalmologists must keep the risk factors for development of in mind and monitor and counsel patients accordingly.

Abstract
Purpose To investigate myopic choroidal neovascularization (mCNV) by fluorescein angiography (FA), spectral-domain optical coherence tomography (SD-OCT), near-infrared (NIR) reflectance, and autofluorescence (AF). Methods This retrospective study included 65 eyes of 62 Caucasian patients with a mean age of 66.72 years (95% confidence interval [CI] 63–70 years) and a mean refraction of −9.72 diopters (95% CI −8.74 to −10.70 diopters). Results Most of the mCNV cases were foveal-juxtafoveal (60/65, 92.3%), with thickening of the corresponding retina (62/65, 95.3%) and leakage on FA (44/65, 67.6%). No retinal fluid was detectable in 32 (49.2%) eyes and there was no hemorrhage in 25 (38.4%) eyes. Papillary chorioretinal atrophy was evident in 58 (89.2%), a shadowing effect in 48 (73.8%), and an epiretinal membrane in 38 (58.4%) eyes. If an area of macular chorioretinal atrophy was present, mCNV frequently developed adjacent to it and was hyperfluorescent rather than with leakage (P⩽0.001). In eyes with edema or hemorrhage, hyper-reflective foci were more frequent (P⩽0.005). NIR and AF features were indeterminable in 19 (29.2%) and 27 (41.5%) eyes, respectively. The predominant feature was black or grayish on NIR (34/65, 52.3%) and patchy (hypo- and hyperfluorescence was observed) on AF (25/65, 38.4%). FA and SD-OCT correctly detected mCNV in 49 (75.3%) and 48 (73.8%) eyes, respectively, whereas NIR and AF exhibited limited diagnostic sensitivity. Doubtful diagnosis was associated with hyperfluorescent mCNV (P⩽0.001), absence of retinal fluid and epiretinal membrane (P⩽0.05), and presence of macular chorioretinal atrophy (P⩽0.01). Conclusion Tomographic, angiographic, AF, and NIR features of mCNV are described in this study. Combination of SD-OCT and FA is recommendable for diagnosis.

Abstract
PURPOSE To report a case of spontaneous combined resolution of vitreomacular traction (VMT) and pigment epithelial detachment (PED). METHODS A 70-year-old woman presented with a 10-day history of metamorphopsia in her right eye. Medical history was unremarkable. The patient underwent a complete ophthalmic examination. Best-corrected visual acuity (BCVA) was 20/50 in the right eye. Fundus examination, fluorescein angiography, indocyanine green angiography, and optical coherence tomography (OCT) revealed a shallow elevated area with irregular edges suggestive of drusenoid avascular PED associated with VMT. RESULTS During the follow-up, OCT showed combined resolution of VMT and PED with almost complete normalization of the outer retinal layers; BCVA increased to 20/40. CONCLUSIONS The temporal sequence of events in our case strongly suggests that the spontaneous resolution of PED could be the consequence of or could be favorably influenced by the VMT resolution.

Abstract
PURPOSE To determine the influence of vitreomacular adhesion (VMA) on treatment outcomes in patients with neovascular age-related macular degeneration who were treated with anti-vascular endothelial growth factor agents using a treat and extend treatment regimen. METHODS A retrospective consecutive case series of 204 eyes from 181 patients with a minimum of 1 year of follow-up at Wills Eye Hospital Retina Service. Vitreomacular interface characteristics were determined by spectral domain optical coherence tomography. One hundred and fifty-three eyes (75%) had no signs of VMA (non-VMA), and 51 (25%) had VMA. RESULTS Baseline mean visual acuity was 20/133 with a mean central retinal thickness of 350.5 μm in the non-VMA group and was 20/145 with 371.8 μm in the VMA group. Mean visual acuity in the non-VMA group was 20/83 and 20/64 at Years 1 and 2, respectively (P < 0.01 to baseline). Mean visual acuity in the VMA group was 20/81 and 20/85 at Years 1 and 2, respectively (P < 0.01 to baseline). The central retinal thickness was 289.71 μm and 267 μm at Years 1 and 2, respectively (P < 0.01 to baseline) in the non-VMA group and was 305.3 μm and 289.24 μm (P < 0.01 to baseline) in the VMA group. The mean total number of injections at Year 1 for non-VMA was 7.4 compared with 8.4 in VMA (P = 0.001) and 5.5 versus 6.7 for the 2 groups in Year 2 (P = 0.027). The mean longest extension at Year 1 was 11.8 weeks compared with 10.1 week (P = 0.005) and for Year 2 was 14.1 weeks compared with 12 weeks (P = 0.041). CONCLUSION The vitreomacular interface seems to have a significant influence on anti-vascular endothelial growth factor treatment intervals but not visual acuity or exudative control outcomes. Eyes with VMA on spectral domain optical coherence tomography at baseline may require more intensive treatment with decreased ability to extend treatment intervals.

Abstract
PURPOSE To iatients with neovascular age-related macular degenernvestigate the role of epiretinal membrane (ERM) on outcomes of anti-vascular endothelial growth factor therapy in pation (nAMD). METHODS This study is a retrospective observational case series and was conducted at the Gazi University School of Medicine, Ankara, Turkey. The reports of the patients with a diagnosis of new-onset nAMD, who were aged at least 50 years and treated with intravitreal anti-vascular endothelial growth factors (ranibizumab or bevacuzimab) between October 2010 and September 2013 in our retina clinic, were reviewed for the vitreomacular interface changes. RESULTS The study included 90 eyes of 90 patients with nAMD. The mean age of the patients was 70 ± 7.5 years, with 35 (38.9%) being male and 55 (61.1%) being female. According to the examinations with optical coherence tomography and B-mode ultrasonography, 43 patients had "concurrent" vitreomacular adhesion (30 focal, 13 broad; Group 1). Twenty-nine patients had complete posterior vitreous detachment (Group 2) and 18 patients (Group 3) had ERM. The number of injections was highest for the patients with ERM (Group 3), and this difference was statistically significant (P < 0.001). The mean interval between injections and the mean longest interval were shorter in Group 3 (P < 0.05). CONCLUSION The presence of ERM in association with nAMD seems to increase the number of anti-vascular endothelial growth factor injections and decrease the injection intervals for the treatment of nAMD. Although the anatomical and functional results are similar in eyes with or without ERM, the increased need for anti-vascular endothelial growth factors may mean that these membranes may decrease the penetration of the drugs through these membranes, which may act as a physical barrier. Additionally, increased inflammation in patients with ERM probably requires more frequent injections.

Abstract
Aim To investigate the qualitative aspects in patient selection and the quantitative impact of disease burden in real world treatment of vitreomacular traction (VMT) and implementation of the National Institute for Health and Care Excellence (NICE) guidance (TA297). Methods A monocentric, retrospective review of consecutive patients undergoing optical coherence tomography (OCT) imaging over a 3 month period. Patients with VMT in at least one eye were identified for further data collection on laterality, visual acuity, symptoms, presence of epiretinal membrane, macular hole and treatment selection. Results A total of 3472 patients underwent OCT imaging with a total of 6878 eyes scanned. Out of 87 patients, 74 patients had unilateral VMT (38 right, 36 left) and 13 patients had bilateral VMT. Eighteen patients with unilateral VMT satisfied NICE criteria of severe sight problems in the affected eye. Eight were managed for a coexisting pathology, one refused treatment, one patient did not attend, two closed spontaneously, and one received ocriplasmin prior to the study start date. Only two patients with unilateral VMT received ocriplasmin and three underwent vitrectomy. Those failing to meet NICE criteria for unilateral VMT were predominantly asymptomatic (n=49) or had coexisting ERM (n=5) or both (n=2). Conclusion Ocriplasmin provides an alternative treatment for patients with symptomatic VMT. Our data shows that the majority of patients with VMT do not meet NICE TA297 primarily due to lack of symptoms. Those meeting NICE criteria, but not treated, tended to have coexisting macular pathology. Variation in patient selection due to subjective factors not outlined in NICE guidance suggests that real world outcomes of ocriplasmin therapy should be interpreted with caution.

Abstract
PURPOSE To investigate the effects of vitreomacular traction (VMT) on ranibizumab treatment response for neovascular age-related macular degeneration (AMD). METHODS A retrospective review of 85 eyes of 85 patients newly diagnosed with neovascular AMD was conducted. Patients were eligible if they had received more than three consecutive monthly ranibizumab (0.50 mg) treatments and ophthalmic evaluations. Patients were classified into a VMT (+) group or VMT (-) group according to optical coherence tomography imaging. Best corrected visual acuity and central retinal thickness (CRT) measurements were obtained at three and six months after initial injection. RESULTS One month after the third injection, mean visual acuity (VA) increases of 6.36 and 9.87 letters were observed in the VMT (+) and VMT (-) groups, respectively. The corresponding mean CRT values decreased by 70.29 µm and 121.68 µm, respectively. A total 41 eyes were identified as eligible for a subsequent fourth injection; 71.1% of patients (27 eyes) in the VMT (+) group but only 29.8% of patients in the VMT (-) group needed a subsequent fourth injection. Follow-up was extended to six months for 42 of the 85 enrolled patients (49.4%). The trends in VA and optical coherence tomography were found to be maintained at six-month follow-up. CONCLUSIONS VA and CRT appeared to be more improved after ranibizumab treatment in the VMT (-) group compared to the VMT (+) group. VMT might antagonize the effect of ranibizumab treatment in a subpopulation of AMD patients.

Abstract
Herein, we review the association between vitreomacular adhesion (VMA) and neovascular age-related macular degeneration (AMD). Meta-analyses have shown that eyes with neovascular AMD are twice as likely to have VMA as normal eyes. VMA in neovascular AMD may induce inflammation, macular traction, decrease in oxygenation, sequestering of vascular endothelial growth factor (VEGF), and other cytokines or may directly stimulate VEGF production. VMA may also interfere with the treatment effects of anti-VEGF therapy, which is the standard treatment for neovascular AMD, and releasing VMA can improve the treatment response to anti-VEGF treatment in neovascular AMD. We also reviewed currently available methods of relieving VMA.

Abstract
Background Previous reports have described a decrease in retinal temperature and clinical improvement of wet age-related macular degeneration (AMD) after vitrectomy. We hypothesized that the retinal temperature decrease after vitrectomy plays a part in the suppression of wet AMD development. To test this hypothesis, we evaluated the temperature dependence of the expression of vascular endothelial growth factor-A (VEGF-A) and in vitro angiogenesis in retinal pigment epithelium (RPE). Results We cultured ARPE-19 cells at 37, 35, 33 and 31°C and measured the expression of VEGF-A, VEGF-A splicing variants, and pigment epithelium–derived factor (PEDF). We performed an in vitro tube formation assay. The dehydrogenase activity was also evaluated at each temperature. Expression of VEGF-A significantly decreased with decreased temperature while PEDF expression did not. VEGF165 expression and in vitro angiogenesis also were temperature dependent. The dehydrogenase activity significantly decreased as the culture temperature decreased. Conclusions RPE cultured under hypothermia that decreased cellular metabolism also had decreased VEGF-A and sustained PEDF expression, creating an anti-angiogenic environment. This mechanism may be associated with a beneficial effect after vitrectomy in patients with wet AMD.

Abstract
Large submacular hemorrhage, an uncommon manifestation of neovascular age-related macular degeneration, may also occur with idiopathic polypoidal choroidal vasculopathy. Submacular hemorrhage damages photoreceptors owing to iron toxicity, fibrin meshwork contraction, and reduced nutrient flux, with subsequent macular scarring. Clinical and experimental studies support prompt treatment, as tissue damage can occur within 24 hours. Without treatment the natural history is poor, with a mean final visual acuity (VA) of 20/1600. Reported treatments include retinal pigment epithelial patch, macular translocation, pneumatic displacement, intravitreal or subretinal tissue plasminogen activator, intravitreal anti-vascular endothelial growth factor (VEGF) drugs, and combinations thereof. In the absence of comparative studies, we combined eligible studies to assess the VA change before and after each treatment option. The greatest improvement occurred after combined pars plana vitrectomy, subretinal tissue plasminogen activator, intravitreal gas, and anti-vascular endothelial growth factor treatment, with VA improving from 20/1000 to 20/400. The best final VA occurred using combined intravitreal tissue plasminogen activator, gas, and anti-vascular endothelial growth factor therapy, with VA improving from 20/200 to 20/100. Both treatments had an acceptable safety profile, but most studies were small, and larger randomized controlled trials are needed to determine both safety and efficacy.

Abstract
BACKGROUND The vitreoretinal interface is not merely the space between the vitreous body and the retina but it is also a site for highly complex pathologies with the vitreous body exerting an influence on all the neighbouring structures. METHODS A literature search was performed in Pubmed and current book articles RESULTS This review article highlights the role of the vitreous body in vitreomacular adhesion and traction, in the development of macular holes and epiretinal membranes as well as its role in age-related macular degeneration. In the retinal periphery the vitreous structures play a pivotal role in retinal tears and detachment as well as in diabetic and other proliferative vitreoretinopathies. The role of the vitreous bodyin the emergence of various forms of cataract is often underestimated. DISCUSSION Vitreo-etinal surgeons should thoroughly understand the pathophysiological relationship between the vitreous body and the neighboring structures, especially in the era of medical vitreolysis.

Abstract
PURPOSE To characterize perifoveal intraretinal cavities observed around full-thickness macular holes (MH) using en face optical coherence tomography and to establish correlations with histology of human and primate maculae. DESIGN Retrospective nonconsecutive observational case series. METHODS Macular en face scans of 8 patients with MH were analyzed to quantify the areas of hyporeflective spaces, and were compared with macular flat mounts and sections from 1 normal human donor eye and 2 normal primate eyes (Macaca fascicularis). Immunohistochemistry was used to study the distribution of glutamine synthetase, expressed by Müller cells, and zonula occludens-1, a tight-junction protein. RESULTS The mean area of hyporeflective spaces was lower in the inner nuclear layer (INL) than in the complex formed by the outer plexiform (OPL) and the Henle fiber layers (HFL): 5.0 × 10(-3) mm(2) vs 15.9 × 10(-3) mm(2), respectively (P < .0001, Kruskal-Wallis test). In the OPL and HFL, cavities were elongated with a stellate pattern, whereas in the INL they were rounded and formed vertical cylinders. Immunohistochemistry confirmed that Müller cells followed a radial distribution around the fovea in the frontal plane and a "Z-shaped" course in the axial plane, running obliquely in the OPL and HFL and vertically in the inner layers. In addition, zonula occludens-1 co-localized with Müller cells within the complex of OPL and HFL, indicating junctions in between Müller cells and cone axons. CONCLUSION The dual profile of cavities around MHs correlates with Müller cell morphology and is consistent with the hypothesis of intra- or extracellular fluid accumulation along these cells.

Abstract
A 74-year-old man had reproducible superior and inferior arcuate visual field defects in the left eye only that were initially believed to be caused by primary open-angle glaucoma. Diagnostic evaluation with the aid of optical coherence tomography revealed extrafoveal vitreomacular traction (VMT) with secondary retinal thickening and schisis. We discuss the evaluation of non-glaucomatous visual field defects and review the literature on the pathogenesis, clinical manifestations, and treatment of VMT syndrome.

Abstract
BACKGROUND AND OBJECTIVE To analyze a variety of vitreomacular traction (VMT) morphologies to establish a major classification that better reflects the preoperative predictive factors of postoperative visual and anatomic outcomes. PATIENTS AND METHODS Thirty-six eyes submitted to vitrectomy surgery were categorized with a VMT pattern (V- or J-shaped) and diameter (focal < 1,500 µm or broad > 1,500 µm) based on optical coherence tomography. RESULTS The researchers compared different classifications of VMT. Despite similar postoperative best corrected visual acuity (BCVA) values (P = .393), cases with focal VMT had greater visual improvement (P = .027) because the preoperative BCVA was significantly lower in the focal group (P = .007). However, the BCVA improvements did not differ between the groups regarding the classic VMT morphologic patterns (P = .235). CONCLUSION Postoperative outcomes and macular disorders are closely related to VMT size. The adhesion diameter (focal or broad VMT) and not the classic VMT morphologic pattern (V- or J-shaped) may better predict the postoperative anatomic and functional outcomes.

Abstract
PURPOSE To determine treatment outcomes of intravitreal ocriplasmin in symptomatic vitreomacular adhesion. DESIGN Retrospective interventional case series. METHODS setting: Private practice. study population: Thirty-five eyes (35 subjects) with symptomatic vitreomacular adhesion. intervention/observation: Intravitreal ocriplasmin injection from February to November 2013. main outcome measure: Vitreomacular adhesion resolution rate. Secondary endpoints included postinjection visual acuity and rates of outer retinal attenuation and full-thickness macular hole (MH) closure. RESULTS The 35 subjects included were of mean age 69 years, 66% female, and 71% phakic. Eleven subjects (31%) had macular comorbidities. Average adhesion diameter was 571 μm, with mean 7.9 months duration of symptoms. Nine subjects (26%) had epiretinal membrane and 6 (17%) had MH (mean diameter 186 μm). Mean preinjection logarithm of the minimal angle of resolution visual acuity was 0.46, and improved to 0.33 at final follow-up. Fifteen eyes (43%) achieved adhesion release at mean 10 days post injection. One of 6 MH (17%) closed. Transient outer retinal attenuation occurred in 10 of 35 cases (29%), with 8 of 10 (80%) achieving adhesion release. One subject (3%) developed a retinal detachment. Adhesion resolution was more likely in patients with younger age (P = .04), absence of comorbidities (P = .02), small adhesion diameter (P = .005), short adhesion duration (P = .03), and transient outer retinal attenuation (P = .008). CONCLUSIONS Intravitreal ocriplasmin efficacy in the private practice setting, while including patients with macular comorbidities, is similar to that of previous studies. Transient toxicity to the outer retina occurs frequently-typically with adhesion resolution-necessitating careful postinjection spectral-domain optical coherence tomography monitoring.

Abstract
PURPOSE Collagen fiber remodeling in the vitreous body has been implicated in cases of vitreomacular traction, macular hole, and retinal detachment, and also may occur during pharmacologic vitreolysis. The purpose of this study was to evaluate quantitative polarized light imaging (QPLI) as a tool for studying fiber organization in the vitreous and near the vitreoretinal interface in control and enzymatically perturbed conditions. METHODS Fiber alignment was measured in anterior-posterior sections of bovine and porcine vitreous. Additional tests were performed on bovine lenses and nasal-temporal vitreous sections. Effects of proteoglycan degradation on collagen fiber alignment using trypsin and plasmin were assessed at the microstructural level using electron microscopy and at the global level using QPLI. RESULTS Control vitreous showed fiber organization patterns consistent with the literature across multiple-length scales, including the global anterior-posterior coursing of vitreous fibers, as well as local fibers parallel to the equatorial vitreoretinal interface and transverse to the posterior interface. Proteoglycan digestion with trypsin or plasmin significantly increased fiber alignment throughout the vitreous (P < 0.01). The largest changes (3×) occurred in the posterior vitreous where fibers are aligned transverse to the posterior vitreoretinal interface (P < 0.01). CONCLUSIONS Proteoglycan loss due to enzymatic vitreolysis differentially increases fiber alignment at locations where tractions are most common. We hypothesize that a similar mechanism leads to retinal complications during age-related vitreous degeneration. Structural changes to the entire vitreous body (as opposed to the vitreoretinal interface alone) should be evaluated during preclinical testing of pharmacological vitreolysis candidates.

Abstract
Vitreomacular traction is a multicategory entity that may cause substantial visual loss due to the formation of a macular hole or traction-induced tissue distortion. The advent of optical coherent tomography (OCT) has demonstrated the anatomic features of persistent vitreomacular attachment (VMA) more definitively, including in many asymptomatic or minimally symptomatic patients. The indications for intervention are unclear, since it is not possible to predict which eyes might be likely to develop progressive visual loss. This has been especially important since for many years, the only treatment option involved surgical intervention (vitrectomy) to release the persistent VMA. Recently, a pharmacolytic agent, ocriplasmin, has become available after many years of development and investigation, and may offer a feasible alternative to surgery, or even a risk/benefit ratio sufficiently favorable to offer intervention at an earlier stage of VMA. Several studies, including a large, prospective clinical trial, have established the foundation of its rationale and efficacy, providing the basis of its approval. The role for ocriplasmin in clinical practice is in the process of being determined. This paper summarizes current knowledge and status of investigations regarding ocriplasmin-induced pharmacologic vitreolysis, and offers some evidence-based considerations for its use.

Abstract
Posterior vitreous detachment (PVD) is a common phenomenon in the aging eye. However, this may be complicated by persistent symptomatic vitreomacular adhesions that exert tractional forces on the macula (vitreomacular traction; VMT). VMT itself may be associated with epiretinal membrane formation and the development of idiopathic macular holes (IMH). Such pathologies may cause visual disturbances, including metamorphopsia, photopsia, blurred vision, and decreased visual acuity, which impact an individual's quality of life. Technologies such as optical coherence tomography allow an increasingly more accurate visualisation of the macular anatomy, including quantification of macular hole characteristics, and this facilitates treatment decision-making. Pars plana vitrectomy remains the primary treatment option for many patients with VMT or IMH; for the latter, peeling of the inner limiting membrane (ILM) of the retina has shown improved outcomes when compared with no ILM peeling. The development of narrow-gauge transconjunctival vitrectomy systems has improved the rate of visual recovery following surgery. Ocriplasmin, by degrading laminin and fibronectin at the vitreoretinal interface, may allow induction of PVD in a non-invasive manner. Indeed, clinical studies have supported its use as an alternative to surgery in certain patient populations. However, further research is still needed with respect to greater understanding of the pathophysiology underlying the development of VMT and IMH.

Abstract
The nature of the vitreoretinal interface in conditions like diabetic macular edema (DME) remains incompletely understood. Furthermore, it is not clear what the role of pharmacological enzymatic vitreolysis will play in cases of vitreomacular traction (VMT) associated with macular disease like DME. We describe the spontaneous resolution of VMT in 2 patients with DME. As both surgical and pharmacologic interventions have been suggested to treat DME in the setting of VMT, we feel that a clarification of the nomenclature and reporting of these cases of natural history may be useful in more fully understanding the complex decision-making involved when determining whether to treat this subset of patients.

Abstract
PURPOSE To evaluate success with intravitreal injection of ocriplasmin in releasing symptomatic vitreomacular traction (VMT). METHODS A retrospective review of consecutive series of patients in a single vitreoretinal practice. Patients with symptomatic distortion and loss of vision secondary to VMT were included in the study. Patients received a single injection of ocriplasmin (JETREA®) and were followed-up after 1 month with optical coherence tomography. RESULTS Eight patients (8 eyes) were included (2 males and 6 females) in the study. Five of 8 eyes (62.5%) experienced complete release of the VMT; one of 8 eyes (12.5%) had partial release of VMT and two of 8 eyes (25%) did not have release of VMT. The two patients with no release of their VMT had the same vision. Of the 5 patients with complete release of VMT, 3 patients had a one line worsening of their vision, 1 had a 4 line improvement of vision, and 1 stayed the same. The patient with only partial release of their VMT had a 1 line worsening of vision. CONCLUSIONS Intravitreal ocriplasmin is a promising treatment option for vitreomacular traction syndrome in symptomatic patients.
