Microincision vitrectomy surgery for myopic foveoschisis

Area of Science:

• Ophthalmology
• Retinal Surgery
• Microsurgery

Background:

• Myopic foveoschisis (MF) is a degenerative condition affecting the macula in highly myopic eyes.
• Surgical intervention is often necessary to address MF and prevent vision loss.

Purpose of the Study:

• To assess the technical feasibility of microincision vitrectomy surgery (MIVS) for MF.
• To evaluate the surgical outcomes, including visual acuity and anatomical restoration, following MIVS in patients with MF.

Main Methods:

• A cohort of 29 patients (33 eyes) with MF diagnosed via spectral-domain optical coherence tomography (SD-OCT) underwent MIVS.
• The surgical procedure involved internal limiting membrane (ILM) peeling, with or without intraocular gas tamponade.
• Postoperative follow-up included best-corrected visual acuity (BCVA) assessment and SD-OCT imaging for 6 months.

Main Results:

• Mean BCVA improved significantly from 1.01 to 0.76 logMAR (p=0.004).
• Central subfield thickness decreased from 431 μm to 231 μm (p<0.001).
• Complete MF resolution and foveal reattachment were achieved in 96% of cases; macular holes closed in all four instances.

Conclusions:

• MIVS with ILM peeling demonstrates favorable visual and anatomical outcomes in highly myopic eyes with MF.
• The technique is technically feasible and offers a promising surgical option for managing this condition.
