Fat adherence syndrome treated with intraoperative mitomycin-C: a rabbit model

Area of Science:

• Ophthalmology
• Ophthalmic Surgery
• Animal Models

Background:

• Restrictive strabismus, similar to human fat adherence syndrome, can impair ocular motility.
• Preventing restrictive scar tissue formation is crucial in ophthalmic surgery.

Purpose of the Study:

• To evaluate the efficacy of topical intraoperative mitomycin-C (MMC) in preventing restrictive scar tissue.
• To assess the safety and potential side effects of topical MMC in an animal model.

Main Methods:

• An animal model of restrictive strabismus was created in rabbits.
• Passive forced ductions were measured before and after treatment.
• Eyes were treated with topical MMC or sterile water, followed by histopathologic examination.

Main Results:

• Significant motility restriction developed in control eyes.
• Topical MMC did not significantly reduce scar tissue formation compared to controls.
• Longer MMC exposure resulted in orbital inflammation and fibrosis.

Conclusions:

• Topical intraoperative MMC was not effective in preventing restrictive scar tissue in this model.
• High concentrations or prolonged exposure to MMC can cause adverse effects.
• Further investigation is required to determine safe and effective delivery methods for MMC in treating fat adherence syndrome.
