The correlation between visual acuity outcomes and optical coherence tomography parameters following surgery for diabetic epiretinal membrane and taut posterior hyaloid

Abstract

PurposeTo evaluate the relationship between visual outcomes and the determinants detected by spectral domain optical coherence tomography (OCT) in eyes with epiretinal membrane (ERM) and/or taut posterior hyaloid (TPH) that underwent pars plana vitrectomy (PPV).Materials and methodsA total of 30 participants with diabetic ERM and TPH were included in the study. All study participants underwent PPV. Preoperative and postoperative best corrected visual acuity (BCVA), peripapillary retinal nerve fiber layer (RNFL), macular RNFL, ganglion cell layer, inner plexiform layer, and ganglion cell complex thicknesses were measured in each participant. Linear regression analyses were performed to determine the association between the OCT parameters and the visual acuity measured at the time of the OCT measurement.ResultsThe postoperative BCVA logarithm of the minimum angle of resolution (logMAR) values were statistically higher than the preoperative values in the ERM group and TPH group (P=0.001 and P<0.001, respectively). The postoperative BCVA logMAR value was negatively correlated with average RNFL, inferior RNFL thicknesses, and image quality (P=0.002, P=0.004, and P=0.006, respectively). The preoperative and postoperative BCVA logMAR value difference was not correlated with age and all of the OCT parameters measured (P>0.05).ConclusionThis study shows that achievement of better peripapillary RNFL thickness results in better visual outcome after PPV and ERM/TPH removal.

“…Yapılan çalışmalarda SAH'nın eşlik ettiği diyabetik maküler ödemli gözlerde PPV sırasında İLM soyulması tanjansiyel traksiyonların giderilmesi açısından faydalı olabilmektedir. [19,31,32] Ivastinovic ve ark., [12] Anti-VEGF'lere dirençli ERM'nin eşlik ettiği DMÖ'sü olan 99 gözde 23G-27G ile vitrektomi, beraberinde ERM ve İLM soyulması uygulamışlar ve olguların ortalama 2 yıl takibinde hem en iyi düzeltilmiş GK' de, hem de santral maküla kalınlıklarında (SMK) önemli bir iyileşme sağladıklarını bildirmişlerdir. [12] PPV ve ERM-İLM soyulmasının DMÖ tedavisinde etkili bir yöntem olduğunu; iyi görme prognozu için ise ELM bozulmadan önce, daha erken dönemde cerrahi uygulanmasını önerdiklerini belirtmişlerdir.…”
