RESUMO

PURPOSE: To evaluate the importance of the status of posterior vitreous in eyes with endophthalmitis following intravitreal anti-vascular endothelial growth factor (anti-VEGF). METHODS: The absence or existence of posterior vitreous detachment (PVD) was elicited in 23 eyes of 23 patients with injection related endophthalmitis, during pars plana vitrectomy (PPV) and compared with 24 control eyes of 24 patients who received intravitreal anti-VEGF without any complication. RESULTS: Thirtten (54.2%) out of 24 patients in the control group had full PVD, whereas only 2 (9.5%) out of 23 eyes in endophthalmitis group (p < 0.001) had full PVD. In all eyes without PVD, posterior vitreous was inducted to be detached at least from optic nerve and macular area without any iatrogenic tear. CONCLUSION: The absence of PVD is a factor that increases the risk of endophthalmitis after intravitreal injections. Uncomplicated separation of the posterior vitreous from the retina in PPV contributes to better prognosis.

RESUMO

PURPOSE: It is commonly accepted that phacoemulsification surgery is a risk factor for the development of posterior vitreous detachment (PVD) and may accelerate the process. This is an important consideration particularly in cases involving young patients who pre-operatively have no PVD, given the increased risk of retinal tears and detachments. METHODS: A comprehensive literature search was conducted to identify studies reporting incidence of PVD post-uncomplicated phacoemulsification surgery. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used for search strategy. Of 3071 titles, 7 studies met the inclusion criteria; The outcomes measured were PVD occurrence by (1) time, (2) type, (3) age, (4) gender and (5) axial length, with all statistical analysis performed using Review Manager. RESULTS: A total of 2034 eyes were included for analysis with a mean follow-up time of 28.3 months. 33.3% of patients developed a PVD, either partial or complete, with rates increasing in a time dependent manner. No significant difference was noted in sub-group analysis by age, gender or axial length. CONCLUSIONS: The results from our systematic review show that uncomplicated phacoemulsification accelerates the physiological process of PVD development. Pre-operative evaluation of the vitreoretinal interface should be performed with careful post-operative follow-up advised in those without a pre-existing PVD.

RESUMO

In this report, two rare cases of large atrophic peripheral retinal holes are described. Both patients presented during a routine visit without reporting any ocular symptoms. The holes did not exhibit significant risk factors for progression to rhegmatogenous retinal detachment: No signs of posterior vitreous detachment, vitreoretinal tractions, or retinal degeneration were visible. For such asymptomatic cases, international guidelines recommend a strict follow-up schedule; however, the unusual size of the holes raised significant concerns about the management of these retinal breaks. The advantages and disadvantages of laser photo-coagulation treatment were discussed, ultimately favoring a watch-and-wait strategy. [Ophthalmic Surg Lasers Imaging Retina 2024;55:176-178.].

RESUMO

AIM: To evaluate the role of papillary vitreous detachment in the pathogenesis of non-arteritic anterior ischaemic optic neuropathy (NAION) by comparing the features of vitreopapillary interface between NAION patients and normal individuals. METHODS: This study included 22 acute NAION patients (25 eyes), 21 non-acute NAION patients (23 eyes) and 23 normal individuals (34 eyes). All study participants underwent swept-source optical coherence tomography to assess the vitreopapillary interface, peripapillary wrinkles and peripapillary superficial vessel protrusion. The statistical correlations between peripapillary superficial vessel protrusion measurements and NAION were analysed. Two NAION patients underwent standard pars plana vitrectomy. RESULTS: Incomplete papillary vitreous detachment was noted in all acute NAION patients. The prevalence of peripapillary wrinkles was 68% (17/25), 30% (7/23) and 0% (0/34), and the prevalence of peripapillary superficial vessel protrusion was 44% (11/25), 91% (21/23) and 0% (0/34) in the acute, non-acute NAION and control groups, respectively. The prevalence of peripapillary superficial vessel protrusion was 88.9% in the eyes without retinal nerve fibre layer thinning. Furthermore, the number of peripapillary superficial vessel protrusions in the superior quadrant was significantly higher than that in the other quadrants in eyes with NAION, consistent with the more damaged visual field defect regions. Peripapillary wrinkles and visual field defects in two patients with NAION were significantly attenuated within 1 week and 1 month after the release of vitreous connections, respectively. CONCLUSION: Peripapillary wrinkles and superficial vessel protrusion may be signs of papillary vitreous detachment-related traction in NAION. Papillary vitreous detachment may play an important role in NAION pathogenesis.

RESUMO

AIM: To report anatomical and functional outcomes after surgical repair of acute-onset vs delayed-onset rhegmatogenous retinal detachments (RDs) following acute posterior vitreous detachment (PVD). METHODS: A retrospective, comparative interventional cohort study where patients presenting to a single-centre retina practice between October 2015 and March 2020 with delayed RDs (diagnosed ≥42 days after initial presentation of acute PVD) were compared with a 2:1 age-matched and gender-matched acute RD cohort (PVD and RD at initial presentation). The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 months after RD repair. RESULTS: A total of 210 eyes were analysed-70 in the delayed RD group and 140 in the acute RD group. SSAS was 58/70 (82.9%) for the delayed RD group and 112/140 (80%) for the acute RD group (p=0.71). At the time of RD diagnosis, mean (SD) logarithm of minimum angle of resolution visual acuity (VA) was 0.51 (0.70) (Snellen, 20/65) in the delayed RD group vs 1.04 (0.92) (Snellen, 20/219) in the acute RD group (p<0.001). Mean VA was better at 1 and 3 months post-repair in the delayed RD group (p=0.005 and 0.041, respectively) but similar by 6 months, 12 months and at the final visit post-repair (p=0.48, 0.27, and 0.23, respectively). CONCLUSIONS: Delayed-onset RDs occurring ≥6 weeks after initial presentation to a retina specialist with an acute PVD generally had better VA at the time of RD diagnosis and faster post-surgical visual recovery compared with acute-onset RDs diagnosed at the initial presentation. No significant difference in anatomic outcomes was seen between the two groups.

RESUMO

PURPOSE: To investigate the predictive factors for postsurgical visual prognosis in patients with vitreomacular traction (VMT). METHODS: This retrospective study enrolled 31 eyes from 29 patients who underwent vitrectomy for idiopathic VMT with a follow-up period of ≥3 months. The VMT was divided into three grades based on optical coherence tomography images: Grade 1 denoted partial vitreomacular separation with foveal attachment; Grade 2 exhibited intraretinal cysts or cleft with grade 1 findings; and Grade 3 was Grade 2 plus the subretinal fluid. RESULTS: Three eyes developed a full-thickness macular hole after surgery, all of which were Grade 3 patients. In the rest 28 eyes, the mean postoperative follow-up period was 23.3 ± 25.8 months. The postoperative central foveal thickness ( P = 0.001) and final best-corrected visual acuity (BCVA; P < 0.001) were both significantly improved from baseline. Fifteen eyes (53.8%) gained ≥ two Snellen lines. Multilinear regression analysis showed that the worse the baseline BCVA ( P = 0.004), or the more advanced the VMT grade ( P = 0.049), the worse the final BCVA. Baseline BCVA was negatively associated with the postoperative visual improvement ( P < 0.001). Those Grade 3 patients with baseline Snellen BCVA of ≥20/40 were more likely to achieve a final Snellen BCVA of ≥20/25 ( P = 0.035). CONCLUSION: The VMT grade is an important predictive factor for the postsurgical visual prognosis. Surgical intervention should be performed as early as possible for Grade 3 patients to prevent further disease progression and maximize the postsurgical visual benefit.

RESUMO

PURPOSE: To assess epiretinal membrane (ERM) formation, severity, and the associated risk factors after scleral buckling using en face optical coherence tomography (OCT) images. METHODS: Medical records of 61 consecutive patients (66 eyes) with rhegmatogenous retinal detachment who underwent scleral buckling were retrospectively reviewed. Posterior vitreous detachment (PVD) was determined based on B-scan OCT images. En face OCT images were used to visualize the ERM and retinal folds. ERM formation was identified by comparing en face images pre- and post-surgery. The maximum depth of the retinal folds (MDRF) was measured using en face imaging to objectively assess traction strength. RESULTS: ERM formation occurred in 15 (22.7%) eyes at the final visit; the foveal pit was preserved in all cases. Parafoveal retinal folds were present in 5 (7.6%) eyes, with a mean MDRF of 21.8 ± 12.6 µm. No significant difference was observed in best-corrected visual acuity (logarithm of the minimal angle of resolution) between the ERM formation (-0.019 ± 0.128) and non-ERM formation (-0.001 ± 0.213) groups at the final visit (P = 0.593; Mann-Whitney U test). Multivariate logistic regression analysis revealed that older age and the presence of PVD were significant risk factors for ERM formation (odds ratio 1.07, 95% confidence interval 1.01-1.14, P = 0.032; odds ratio 5.26, 95% confidence interval 1.06-26.10, P = 0.042; respectively). CONCLUSION: ERM occurred in 22.7% of cases but was mild and did not affect visual acuity. Older age and the presence of PVD are risk factors for ERM formation.

RESUMO

PURPOSE: To explore the characteristics of vitreoretinal lymphoma (VRL) in B-scan ultrasonography. DESIGN: Single-center case-control study. PARTICIPANTS: A total of 106 eyes of 56 patients with biopsy-proven VRL and 86 eyes of 59 patients with uveitis were included. METHODS: B-scan ultrasonography of the included eyes was performed. Evaluated were the ultrasonographic signs as well as a special pattern termed centrifugal condensation, which refers to the peripherally hyperreflective appearance of the vitreous haze in ultrasonography. MAIN OUTCOME MEASURES: Posterior vitreous detachment, vitreoretinal adhesion, location of vitreous haze, thickening or occupying lesions of the retina, retinal detachment, and centrifugal condensation pattern of vitreous haze were evaluated through B-scan ultrasonography. The incidences of these signs were compared between the 2 groups; odds ratios (ORs) were calculated. RESULTS: The incidence of vitreoretinal adhesion in patients with VRL (6/106) was lower than in patients with uveitis (20/86; P = 0.001; OR: 0.195; 95% confidence interval [CI]: 0.073-0.522). The incidence of retinal thickening or occupying lesions in patients with VRL (21/106) was higher than that in patients with uveitis (1/86; P = 0.005; OR: 19.068; 95% CI: 2.455-148.265). The incidences of posterior vitreous detachment and retinal detachment were not significantly different between the 2 groups (P = 0.453 and P = 0.310, respectively). The centrifugal condensation pattern was more likely to be observed in patients with VRL (49/106) than in patients with uveitis (13/86; P < 0.001; OR: 4.831; 95% CI: 2.416-9.660). CONCLUSIONS: B-scan ultrasonography might help to provide clues for the suspicion of VRL. Thickening or occupying lesions of the retina and centrifugal condensation pattern of vitreous haze might be suggestive of VRL.

RESUMO

PURPOSE: To investigate the effect of posterior vitreous detachment (PVD) on visual acuity (VA) after implantation of a diffractive multifocal intraocular lens (mIOL). SETTING: Eye Clinic, Okayama, Japan. DESIGN: Retrospective case series. METHODS: This study evaluated 475 eyes of 475 patients who underwent cataract surgery with a TECNIS Multifocal ZLB00 lens implant between November 2017 and October 2019. Patient eyes were classified into the complete PVD group (PVD group) or the control group with no PVD/partial PVD (non-PVD group) and divided into 3 age categories: 65 to 69, 70 to 74, and 75 to 79 years. The postoperative VA of the PVD and non-PVD groups was compared between and within groups by age. RESULTS: Distance-corrected near VA (DCNVA) was significantly worse in the PVD group than in the non-PVD group in all age categories ( P ≤ .029). In the PVD group, both corrected distance VA (CDVA) and DCNVA were significantly worse in the 75 to 79 years age group than in the 65 to 69 and 70 to 74 years age groups ( P ≤ .034). CDVA and DCNVA in the non-PVD group did not differ significantly between age categories. CONCLUSIONS: The results of this study suggest that complete PVD worsens near VA in eyes with a diffractive mIOL. Furthermore, eyes with complete PVD may show an age-related decline in both CDVA and DCNVA. In particular, eyes ≥75 years of age with complete PVD have a poor visual prognosis and should be given careful consideration when deciding whether to implant a diffractive mIOL.

RESUMO

BACKGROUND: Intravitreal anti-vascular endothelial growth factor (VEGF) is the standard treatment for exudative age-related macular degeneration (AMD). The constitution of the vitreomacular interface varies greatly in cases of attached (with or without traction) or detached vitreous body, which can impact the effectiveness of the anti-VEGF treatment. OBJECTIVE: Based on the current literature this article displays the current state of the science on whether the constitution of the vitreous body has an effect on the anti-VEGF treatment. MATERIAL AND METHODS: The published data extracted from current trials and post hoc analyses concerning this topic are presented and put into the clinical context. RESULTS: The presence of a vitreomacular adhesion reduces the efficacy of anti-VEGF treatment of exudative AMD. Posterior vitreous body detachment represents a positive prognostic factor concerning the efficacy of anti-VEGF treatment but not necessarily the prognosis for visual acuity. CONCLUSION: Patients with attached vitreous body need a more intensive treatment monitoring compared to patients with detached vitreous body. Therefore, in eyes with initial posterior vitreous body detachment receiving a treat and extend regimen, the interval between anti-VEGF injections can be extended to 4 instead of 2 weeks without endangering the success of treatment.

RESUMO

Background and Objectives: This study aimed to establish possible connections between macular dynamics, various macular features, and visual acuity prognosis among patients with retinal vein occlusions. Materials and Methods: This study included 85 patients with central retinal vein occlusions (CRVO) and 26 with branch retinal vein occlusions (BRVO). We assessed macular features such as central macular thickness (CMT), foveal intraretinal hemorrhage (IRH), the presence and distribution of hyperreflective foci (HF), ellipsoid zone (EZ) disruption, inner retinal layer disorganization (DRIL), and posterior vitreous detachment (PVD), as well as their dynamics over one year of observation and their impact on final visual acuity prognosis, depending on the type of occlusion. Results: Best corrected visual acuity (BCVA) evolution is statistically significant regarding groups of age and type of occlusion and insignificant regarding gender. The best response to intravitreal treatment, quantified as a decrease in CMT, was registered after the first intravitreal injection. Connecting a decrease in CMT with BCVA improvement, we did not register a statistically significant correlation in the CRVO group, only in BRVO cases. The study results showed that complete PVD plays a significant positive role in decreasing CMT and BCVA improvement in cases of CRVO. Our study revealed that no matter the type of occlusion, the presence of foveal IRH will have a negative impact on the BCVA outcome. Statistically significant differences have been noted only for the evolution of visual acuity in non-ischemic CRVO cases, in correlation with the presence of EZ disruption. Outer retinal layer HF has proved to be a predictive factor for poor visual acuity outcomes. Conclusions: The most important non-imaging predicting factors regarding BCVA after retinal vein occlusions are age and baseline BCVA. CMT's dynamics still establish a weak connection with visual acuity fluctuations. The presence of foveal IRH, outer retinal layer HF, and foveal EZ disruption has a negative impact on visual acuity outcomes.

RESUMO

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.

RESUMO

Purpose: To investigate the impact of phacoemulsification on posterior vitreous detachment formation in eyes with vitreomacular traction (VMT) with or without macular holes. Methods: A retrospective search of the medical records was conducted to identify patients with VMT who underwent cataract surgery at Mass Eye and Ear from 2016 to 2021. Patient demographics, ocular comorbidities, and clinical characteristics were extracted from the record, and optical coherence tomography images were assessed to confirm VMT and the presence of a lamellar or full-thickness macular hole (FMTH). Patients who underwent vitrectomy prior to cataract surgery were excluded. Results: A total of 22 patients (15 women [68%]) met inclusion criteria (average age, 71 years). Fifteen eyes had an associated epiretinal membrane (63%), 7 had a lamellar hole (29%), and 8 had an FTMH (33%). Epiretinal membrane was present in 3 of 7 eyes with lamellar holes (43%) and 4 of 8 with a FTMH (50%). No eyes developed a complete posterior vitreous detachment following phacoemulsification. In 2 cases, there was progression of the macular hole stage following phacoemulsification. Ten eyes underwent subsequent pars plana vitrectomy (PPV). There was no statistically significant difference in visual acuity between eyes pre- and post-phacoemulsification; however, there was a statistically significant improvement in visual acuity pre- and post-PPV. Conclusions: Unlike other studies, in this case series of 24 eyes with VMT or VMT with holes, no cases of full posterior vitreous detachment occurred following unremarkable phacoemulsification or YAG capsulotomy.

RESUMO

PURPOSE: To describe and evaluate the effectiveness of the Kaminari Kagura technique as a posterior hyaloid detachment treatment. STUDY DESIGN: This was a prospective, consecutive, randomized interventional study. METHODS: This study examined 30 eyes from 30 patients divided into two groups: (1) a Kaminari Kagura group (15 eyes) and (2) a control group (15 eyes) scheduled for vitrectomy with an optical coherence tomography (OCT)-based diagnosis of adherent posterior hyaloid. RESULTS: The mean time for posterior vitreous detachment (PVD) induction in the Kaminari Kagura group was 58 ± 6.6 s, and that in the control group was 69 ± 9 s (p < 0.005). No intra- or post-operative complications were reported. CONCLUSIONS: The Kaminari Kagura technique results in effective posterior hyaloid detachment in less time than that required for posterior vitreous cortex engagement.

RESUMO

BACKGROUND AND OBJECTIVE: Inducing a posterior vitreous detachment (PVD) may be challenging, especially in pediatric patients with firm vitreo-retinal adherence. This case report will present an alternative method of PVD induction using adjunctive perfluorooctane (PFO). MATERIALS AND METHODS: An 11-year-old boy underwent scleral buckle placement and 23-gauge pars plana vitrectomy for macula-off retinal detachment. Triamcinolone acetonide was used for vitreous staining. A flexible loop was used to peel the hyaloid membrane from attached retina nasal to the optic nerve. A small hole was created in the posterior hyaloid, and a small PFO bubble was injected under the detached vitreous to further dissect it from the retina and propagate the vitreous detachment anteriorly. The vitrector was used to lift and complete the PVD peripherally. RESULTS: PVD induction was obtained with no iatrogenic retinal breaks or postoperative complications. CONCLUSION: PVD induction using a stepwise PFO approach is a safe and effective alternative to conventional techniques. [Ophthalmic Surg Lasers Imaging Retina 2023;54:543-546.].

RESUMO

We describe a case of myopic traction maculopathy (MTM) in a patient with low myopia that resolved with surgical intervention. Our patient demonstrated no other features of myopic degeneration and none of the typical tractional elements that cause MTM, such as vitreomacular traction due to partial posterior vitreous detachment (PVD) with vitreomacular adhesion, epiretinal membrane, or a remnant cortical vitreous layer following PVD. Possible pathogenic mechanisms in our patient include reduced compliance of the aging internal limiting membrane and/or traction from elasticity within the thin cortical vitreous layer that forms the posterior wall of the premacular liquefied pocket.

RESUMO

INTRODUCTION: The aim of this study was to examine if choroidal vascularity index (CVI) is different in eyes with unilateral vitreomacular traction (VMT) from their healthy fellow eyes; and whether different treatments affect the CVI. METHODS: The baseline and 8-week post treatment CVIs of 56 unilateral VMT patients that underwent spontaneous resolution (n = 30), vitreoretinal surgery (n = 16) or pneumatic vitreolysis (n = 10) were compared with fellow eyes using paired samples t-test. Partial correlation analyses correcting age and gender was used for calculations between treatment groups. P values < 0.05 were considered statistically significant. RESULTS: The mean baseline CVI for VMT and control eyes had no statistically significant difference (p = 0.81, r= -0.38). The post traction release follow-up CVI of VMT eyes and contralateral eyes had no significant difference (p = 0.12, r = 0.49). In spontaneous resolution group, vitreoretinal surgery group and pneumatic vitreolysis group the baseline and follow up CVIs of VMT eyes were statistically similar (p = 0.72, p = 0.32 and p = 0.79 respectively).Spontaneous detachment patients' CVIs showed a 0.57±5.81% increase, vitreoretinal surgery group had a reduction of 1.098±4.76%, and the pneumatic vitreolysis patients showed a CVI reduction of 0.307±4.24%. However, none of these changes was found to be statistically significant when compared between the groups (p = 0.21, r = 0.02). DISCUSSION: Previous studies have argued that vitreomacular traction might have a role on the choroidal changes seen in the vitreoretinal interface disorders. This study has shown that VMT alone does not cause any significant changes in choroidal vascular index pre or post traction release.

RESUMO

PURPOSE: To present a case of a myopic macular hole that spontaneously closed twice in the presence of a broadly adherent posterior hyaloid membrane. METHODS: Case report. RESULTS: A 49-year-old man with high myopia and pseudophakia had a full-thickness macular hole in the left eye. The hole spontaneously closed in all retinal layers before the elective surgery, but the macular hole recurred one month later. The hole started sealing again spontaneously after one month, leaving a defect in the outer retinal layers. Four months later, the outer layer defect sealed and a lamellar macular hole developed. Throughout the course, the posterior hyaloid membrane remained parallel to the macular surface. The macular morphology and the patient's vision remained stationary at the 2-year follow-up. CONCLUSION: This case demonstrated that myopic macular holes can form and seal repeatedly with a broadly adherent posterior hyaloid membrane. Although bridging phenomenon was the common sign indicating the initiation of the two hole closures, different patterns of tissue regeneration ensued.
