“…[ 32 ] The reason for this could be that the mechanical microscopic trauma of ERM-ILM peeling caused by the use of intraocular forceps affects the outer retinal structure through the Muller cells. [ 36 , 37 ] Nevertheless, these changes seem to have no significant impact on postoperative functional outcome. [ 36 ]…”

IntroductionTo highlight the differences in macular pigment optical density (MPOD) between eyes with vitreoretinal interface syndrome and healthy control eyes, to assess the changes in MPOD in eyes treated with macular peeling, to investigate the relationships between MPOD changes and measures of retinal sensitivity such as best corrected visual acuity (BCVA) and microperimetry.MethodsIn this cross-sectional comparative study, 30 eyes affected by idiopathic epiretinal membrane (iERM, 15eyes) or full-thickness macular hole (FTMH, 15eyes) were compared with 60 eyes from 30 healthy age-matched patients. MPOD values (mean MPOD, maximum MPOD, MPOD area, and MPOD volume) were measured in a range of 4°–7° of eccentricity around the fovea, using the one-wavelength reflectometry method (Visucam 200, Carl-Zeiss Meditec). Patients affected by iERM and FTMH were treated with vitrectomy and epiretinal membrane-inner limiting membrane (ERM-ILM) peeling, with follow-up examinations performed preoperatively and 6 months postoperatively. The main outcome measures were the differences in MPOD between eyes with vitreoretinal interface syndrome and healthy eyes, changes in MPOD after ERM-ILM peeling, and relationships between MPOD and functional changes.ResultsMean MPOD differed significantly between control eyes and those with iERM (P = .0001) or FTMH (P = .0006). The max MPOD and MPOD area increased, but not significantly. After peeling, the only significant change in MPOD was in MPOD volume (P = .01). In the ERM group, postoperative mean MPOD correlated significantly with best-corrected visual acuity (r = .739, P = .002).ConclusionsMPOD was reduced in patients with iERM or FTMH compared with healthy eyes. We found a significant correlation between the mean postoperative MPOD and postoperative BCVA, hypothesizing that the postoperative increase in mean MPOD could be due to a change in distribution for unfolding and expansion of the fovea after the peeling. MOPD may be considered as a prognostic factor associated with a good visual prognosis in patients with iERM.

“…In our study, the mean BCVA in all 65 patients was 0.30 ± 0.13 logMAR, and was found to be worse than in patients with separate ERM or VMT [23,24,25,26]. Further analysis of our results showed that, in the cases where VMT and ERM were unified (group I), the BCVA was statistically significantly lower than in patients with no intercorrelation between VMT and ERM (group II).…”

“…Previous studies focusing on the changes of BCVA in the presence of ERM and VMT have reported a BCVA of about 0.28 logMAR in cases with VMT alone [23]; in patients with ERM alone, it has ranged from 0.6 ± 0.2 to 0.28 logMAR [24,25,26]. In our study, the mean BCVA in all 65 patients was 0.30 ± 0.13 logMAR, and was found to be worse than in patients with separate ERM or VMT [23,24,25,26].…”

Purpose: The purpose of this study was to evaluate the anatomical and functional findings in patients with vitreomacular traction (VMT) combined with epiretinal membrane (ERM) in the same eye. Methods: In this retrospective, cross-sectional study, we studied 65 patients with VMT and ERM. In 36 of them, ERM/VMT had a ‘unified' appearance (group Ι) but in 29, VMT and ERM coexisted without an interrelationship (group ΙΙ). All patients were examined with spectral-domain optical coherence tomography (SD-OCT). We recorded the macular thickness, the presence, type and location of macular edema, the horizontal diameter of VMT, ellipsoid zone/external limiting membrane (EZ/ELM) status, the vitreofoveal angle of VMT nasally and temporally and the best corrected visual acuity (BCVA). Results: Group Ι presented with increased macular thickness, a broader adhesion diameter, extensive EZ/ELM defect and decreased BCVA compared to those where VMT and ERM were not intercorrelated. In group I (‘unified' VMT and ERM), cystoid macular edema was found at a greater percentage (41.7%), while in patients where the 2 entities were not intercorrelated, diffuse macular edema was more evident (69%). There was no statistically significant difference between the 2 groups in the vitreofoveal angle temporally and nasally. Conclusions: Macular thickness, type of macular edema, adhesion diameter, the extent of the EZ/ELM defect and BCVA appeared different in cases where VMT and ERM were unified compared to cases where ERM and VMT coexisted but were not intercorrelated.

“…Vitrectomy [2] is a surgery to remove some or all of the vitreous humor from the eye, to restore the light path and the eye function. It is now a routine clinical operation for various eye disorders such as diabetic eye disease (diabetic retinopathy) [3][4][5], retinal detachments [6][7][8][9][10], macular hole [11][12][13] and macular pucker [14,15]. However, due to the anatomical location of the vitreous body and the complexity of the operation, the patients tend to develop various psychological disorders before and upon the operation, which would negatively affect the therapeutic effects and their eyesight recovery.…”

Aims and Objectives: To determine the effects of the comprehensive care to the psychological status and the eyesight recovery of the patients with vitrectomy. Background: Vitrectomy is a routine clinical practice which was widely used to treat multiple eye diseases. However, due to the anatomic location of the vitreous body and the operational risk, patients tend to develop psychological disorders, which would negatively affect the therapeutic effects. Design: 84 cases of the patients who had the vitrectomy operation in our hospital during the period of February 2015 to February 2017 were randomly divided into control group (n=42) and experimental group (n=42). The control group accepted the routine care during and after the operation, and the experimental group accepted the comprehensive care in addition to routine care. Methods: The effects of comprehensive care were evaluated by comparing the psychological status of the patients and the extent of the eyesight recovery between the two groups. Results: Both the self-rating anxiety scale (SAS) and the self-rating depressive scale (SDS) of the experimental group are significantly (p<0.01) lower than the control group. The eyesight recovery efficiency in experimental group (92.86%) is significantly higher (p<0.05) than control group (76.19%). The incidence of postoperative complications in experimental group is significantly lower (p<0.05) than control group, and the average length of stay in hospitals in experimental group is significantly shorter (p<0.01) than control group. Conclusions: There were significant beneficial effects of the comprehensive care in patients with vitrectomy. Comprehensive care could effectively improve the psychological statues of the patients and enhance their eyesight recovery. Relevance to clinical practice: Comprehensive care in patients underwent surgery improve patient's recovery and make a difference in disease outcomes. This could potentially be applicable to most of the clinical practices.
