“…6 VA testing alone cannot account for the disabling symptoms associated with early ERMs such as distortion, blurring, and micropsia. Snellen's VA does not completely reflect the true predicament these patient regularly experience, especially under a low contrast set-up.…”

Purpose To establish whether early vitrectomy for epiretinal membrane (ERM) is preferable to delayed surgery. Methods We carried out a retrospective study of 120 eyes from 120 patients with preoperative visual acuity (VA) of 6/60 or better. Pre-operative logMAR score was considered to act as an appropriate proxy measure for time of surgical procedure, with scores of 0.3 or less considered to represent early surgery, scores of 0.4 or 0.5 considered to represent medium surgery, and scores of 0.6 or more considered to represent late surgery for ERM. Patients were either pseudophakic at the time of vitrectomy or underwent combined phacovitrectomy for symptomatic ERM. Results Evaluation of parameter coefficients indicated that controlling for other factors, a delay of the surgical procedure from a state of early to medium corresponded to an increase (ie, disbenefit) of 0.074 units in postoperative logMAR score (95% confidence interval À 0.001-0.15). A delay of the surgical procedure from a state of early to late corresponded to an increase (ie, disbenefit) of 0.21 units in post-operative logMAR score (95% confidence interval 0.13-0.29). Mean post-operative VA for early surgery was 0.16, out of which 36.2% of patients had a LogMAR score of 0.1 or better. This is in comparison to 17.2% in late ERM (those with a pre-operative logMAR score of 0.6 or more). Conclusion We conclude that early surgery is associated with a lower (ie, better) postoperative logMAR score. Vitrectomy for early symptomatic ERM, in carefully selected patients, is beneficial in preserving excellent vision and allows quicker visual rehabilitation.

“…Therefore, it is the patient's own judgement of the visual impairment that is important. Patients' subjective evaluations of the effect of the surgery have been analysed in studies using interviews (Scott et al 1998) and questionnaires (Ghazi-Nouri et al 2006;Okamoto et al 2009); all of which found that the severity of metamorphopsia correlated to quality of life but not to VA. A common method for measuring subjective experience is the visual analogue scale (VAS) (Papas & Schultz 1997;Weed & McGhee 1998). To our knowledge it has not been used in evaluating the subjective results of surgery for ERM.…”

ABSTRACT.Purpose: To examine pre-and postoperative visual interference, subjective symptoms and visual acuity in patients undergoing epiretinal membrane (ERM) surgery. Methods: A retrospective observational case series comparing 239 eyes in 231 consecutive patients with idiopathic ERM in a selected catchment area from 2002 to 2009. Demography, visual acuity (VA), lens status and subjective symptoms were analysed before and after the operation. Patients, healthy enough to participate at least 2 years post surgery, answered a questionnaire about their subjective functional impairment before and after the ERM peeling. Visual disturbance was assessed on a visual analogue scale (VAS) ranging from 1 to 100 mm. Results: The preoperative VA for the eyes in the study was median 0.40 logMAR (logarithm of the minimum angle of resolution) (range À0.1 to 1.22) resulted in VA of 0.22 logMAR (range À0.1 to 1.1), which is a statistical significant difference (p À). Of 180 patients contacted, answers were received from 103 (57%). Subjective visual disturbance assessed on the VAS showed a median of 70 mm (range 0-100) before surgery compared to a subjective disturbance median 27 mm (range 0-98) postoperatively. The change preoperatively to postoperatively was mean À34 mm (SD 31), median À37 (range À96 to 37), p À. Patients with much disturbance at baseline measured by VAS experienced more subjective benefit of the operation measured by the distance between the mark on the VAS preoperatively and postoperatively, p À, Spearman correlation coefficient. Conclusion: Patients with considerable preoperative disturbance benefit more from an operation than those with less disturbance.

“…Thus, it is essential to evaluate the visual outcome in terms of the quality of vision as well as by the visual acuity. Okamoto et al 1,2 demonstrated that the changes in metamorphopsia but not the visual acuity were significantly associated with changes in the 25-item National Eye Institute Visual Function Questionnaire composite score on the quality of vision after ERM surgery. Therefore, assessing not only the visual acuity but also the severity of metamorphopsia is important when deciding the timing of the ERM surgery and for evaluating the postoperative quality of vision.…”

“…Several researchers have used the M-CHARTS and have reported the changes in metamorphopsia before and after the removal of an ERM. 1,2,8,9 Others 4,5,10 have used the charts or a laser grid to follow the changes in metamorphopsia after ERM surgery. However, these studies did not follow the changes but examined the severity of metamorphopsia before and only at a fixed postoperative time.…”

PURPOSE.To follow the changes in the metamorphopsia, visual acuity, and OCT parameters after epiretinal membrane (ERM) removal.METHODS. The study included 49 eyes of 49 patients with an ERM who underwent vitrectomy and membrane peeling. The changes in the best-corrected visual acuity (BCVA), metamorphopsia, and central foveal thickness (CFT) were evaluated at baseline and 1, 3, 6, 9, and 12 months postoperatively. M-CHARTS were used to quantify metamorphopsia. RESULTS.The mean BCVA, metamorphopsia scores for horizontal lines (MH) and vertical lines (MV), and CFT improved significantly at 12 months after surgery (P < 0.001). The baseline BCVA, MH score, and MV score were significantly correlated with the corresponding BCVA, MH score, and MV score at 12 months after surgery (P < 0.01). The MH and MV scores at 12 months was significantly correlated with the BCVA at 12 months (P < 0.01), and the baseline MV score was significantly correlated with the BCVA at 12 months (P < 0.05). The MH score but not the MV score was significantly correlated with the CFT at baseline and 12 months (P < 0.05).CONCLUSIONS. The preoperative BCVA, MH score, and MV score were prognostic factors for the corresponding postoperative BCVA, MH score, and MV score. These results suggest that surgery for ERM should be considered before severe reduction in the BCVA or the degree of metamorphopsia. In addition, the preoperative MV score was a prognostic factor for postoperative BCVA. The MH score but not the MV score was correlated with the CFT preoperatively and postoperatively. (Invest Ophthalmol Vis Sci. 2012;53:3592-3597) DOI:10.1167/ iovs.12-9493 P atients with an idiopathic epiretinal membrane (ERM) often suffer from metamorphopsia, which impairs the quality of vision even when the conventional visual acuity is relatively good. To resolve these visual difficulties, these eyes commonly undergo vitrectomy with the removal of the ERM. Despite a successful removal of an ERM and an improvement of the visual acuity, the patient's quality of vision may not be completely normal mainly because of residual metamorphopsia. Thus, it is essential to evaluate the visual outcome in terms of the quality of vision as well as by the visual acuity. Okamoto et al.1,2 demonstrated that the changes in metamorphopsia but not the visual acuity were significantly associated with changes in the 25-item National Eye Institute Visual Function Questionnaire composite score on the quality of vision after ERM surgery. Therefore, assessing not only the visual acuity but also the severity of metamorphopsia is important when deciding the timing of the ERM surgery and for evaluating the postoperative quality of vision.Amsler charts have been widely used for detecting metamorphopsia, 3 but it is difficult to quantify the severity of the metamorphopsia. Some investigators have evaluated metamorphopsia by the numbers of distorted squares on the Amsler charts 4 or a laser grid generated by a scanning laser ophthalmoscope, 5 but these findings represent the range rather than the ...
