Abstract

Objective: To report the clinical and surgical outcomes of patients with myopic foveoschisis (MF).

Methods: Thirteen eyes in ten symptomatic MF patients
who underwent pars plana vitrectomy (PPV) and gas tampon­ade with
internal limiting membrane (ILM) peeling were retrospectively
identified. Best corrected visual acuity (BCVA) and central foveal
thickness (CFT) were assessed preoperatively and six months
postoperatively. Complications during and after surgery were also
recorded.

Results: The median BCVA significantly improved from
20/160 to 20/100 (p = 0.03). In subgroup analysis, eight eyes (61%)
demonstrated significant BCVA improvements from 20/80 to 20/50 (p <
0.001), whereas five eyes had similar BCVA with preoperative level after
six months of surgery (p=0.32). The mean CFT decreased from 526 microns
at base­line to 214 microns at six months of surgery (p < 0.001).
Optical coherence tomography scans revealed a complete MF resolution in
ten eyes (76%) and a partial MF resolution in three eyes. Peripheral
retinal tear was developed in one patient during surgery and one patient
had cataract after surgery, those were treated accordingly.

Conclusion: PPV with ILM peeling followed by gas
tamponade is a safe and effective procedure for the treatment of eyes
with myopic foveoschisis. Larger studies with longer follow-ups will
further establish the efficacy and safety of this procedure. J Clin Exp Invest 2016; 7 (2): 139-143
