Retinal microvascular differences after successful macular hole surgery by using the superior and temporal inverted...

Area of Science:

• Ophthalmology
• Retinal Surgery
• Microvascular Imaging

Background:

• Idiopathic macular holes (IMHs) are a common cause of visual impairment.
• Surgical repair is the primary treatment for IMHs.
• Inverted flap techniques are utilized for macular hole closure.

Purpose of the Study:

• To compare retinal microvascular changes after macular hole surgery.
• To evaluate the safety of superior versus temporal inverted flap techniques.
• To assess vessel density (VD) in superficial and deep capillary plexuses post-surgery.

Main Methods:

• Retrospective analysis of patients with IMHs (250-400 μm diameter).
• Comparison of 14 eyes treated with superior inverted flap vs. 15 eyes with temporal inverted flap.
• Assessment of VD in central and parafoveal areas at baseline and 6 months post-op.

Main Results:

• Significant improvement in best-corrected visual acuity (BCVA) in both groups.
• No significant difference in BCVA between the superior and temporal flap groups.
• Increased superficial capillary plexus (SCP) VD in the central area; no significant change in deep capillary plexus (DCP) VD or parafoveal VD.

Conclusions:

• Both superior and temporal inverted flap techniques are safe for retinal microvasculature.
• Macular hole surgery using these flap techniques does not adversely affect retinal microvascular density at six months.
