Abstract
Purpose :
To assess the retinal architectural changes following fovea sparing internal limiting membrane peeling (FSIP) for high myopic retinoschisis by utilizing intraoperative optical coherence tomography (iOCT). Visual acuity changes before and after surgery was also evaluated.
Methods :
Qualitative assessment of retinal architecture alterations imaged with an iOCT. An iOCT device was utilized to assess the retinal architectures prior to and following FSIP or internal limiting membrane (ILM) peeling (peel-off) in 15 eyes with high myopic retinoschisis. The alterations of foveal architectures, existence of foveal detachment, occurrence of foveal detachment and full thickness macular hole (FTMH) were analyzed. The visual acuity prior to and following vitrectomy were also compared in each group.
Results :
FSIP were performed for 6 cases. No case showed any significant retinal architectural changes during surgery. Among the 9 cases of the cases following ILM peeling (peel-off), 2 cases showed the FTMH (22%), one case showed deterioration of foveal detachment (11%), two cases showed development of cracks like configuration at inner retina (22%, figure, arrow) and 1 case showed a thinner retina (11%). The postoperative best-corrected visual acuity (BCVA) eyes which underwent FSIP (0.28 in logMAR) was significantly better than the preoperative BCVA (0.81 in logMAR, P < 0.05, Mann-Whitney U test) but not in the eyes which performed a complete ILM peeling (0.64 in logMAR preoperatively 0.38 in logMAR postoperatively).
Conclusions :
We could evaluate the alteration of foveal architecture after ILM peeling and efficacy of the FSIP during surgery.
