Correlation Between OCT and mFERG Findings With VA After Vitrectomy Surgery for Retinal Detachment

Correlation Between Optical Coherence Tomography and Multifocal Electroretinogram Findings With Visual Acuity After Vitrectomy Surgery for Retinal Detachment

Correlation between optical coherence tomography and multifocal electroretinogram findings with visual acuity after vitrectomy surgery for Retinal detachment.

Although the anatomical success rate of vitreoretinal surgery has improved over the last decade, visual results remain compromised? Patients with macula-off retinal detachments (RDs) can have poor visual recovery, specific color vision defects, or metamorphopsia postoperatively despite successful retinal reattachment. In these cases, subtle changes in the foveal structure may be causing visual disturbances that can be difficult to identify during standard clinical examinations such as slit lamp biomicroscopy or binocular indirect ophthalmoscopy .reported a possible association between incomplete visual recovery and the presence of residual subretinal fluid (SRF) postoperatively.

Optical coherence tomography (OCT) is a non-invasive technique that provides information about the morphology of the retina, and especially of the macular area in vivo. Some studies support the idea that OCT determines structural changes in the macula that are correlated with subjective visual function, including visual acuity (VA) in patients with vitrectomy for retinal detachment. Additionally, multifocal electroretinogram (m fERG) evaluation can be helpful in assessing macular function in post-vitrectomy. However, to date, there are relatively few reports concerning the combined use of OCT and m fERG for the correlation between retinal morphology and function of the macula in patients with vitrectomy for retinal detachment surgery. The purpose of our study is to determine whether a significant correlation exists between the amplitude of m fERG, visual acuity, and the morphological OCT changes by in the macula after vitrectomy for retinal detachment
