Silicone oil tamponade for persistent macular holes

Area of Science:

• Ophthalmology
• Retinal Surgery

Background:

• Persistent or recurrent macular holes pose a challenge after initial surgery.
• The optimal re-treatment strategy remains under debate.
• Conventional silicone oil tamponade is explored as a re-treatment option.

Purpose of the Study:

• To evaluate the anatomical and functional outcomes of temporary silicone oil tamponade for persistent or recurrent full-thickness macular holes.
• To compare the efficacy of silicone oil tamponade with alternative surgical therapies.

Main Methods:

• Retrospective analysis of patients with persistent/recurrent macular holes post-vitrectomy and gas tamponade.
• Re-treatment with temporary silicone oil tamponade and free postoperative positioning.
• Assessment of anatomical closure via optical coherence tomography and visual acuity changes (BCVA).

Main Results:

• Silicone oil tamponade achieved a 90.9% closure rate in 33 eyes.
• Median best-corrected visual acuity (BCVA) improved significantly post-silicone oil removal (p=0.010).
• Functional improvement was observed in 61.3% of eyes with successful closure (p=0.0005).

Conclusions:

• Temporary conventional silicone oil tamponade is effective for persistent or recurrent full-thickness macular holes.
• This approach yields high anatomical closure rates and significant visual acuity improvement.
• No postoperative positioning was required, simplifying the treatment regimen.
