Patient selection important for successful Müller’s muscle-conjunctival resection

WAILEA, Hawaii — Proper patient selection is key for success during Müller’s muscle-conjunctival resection, or MMCR, according to a speaker here.
“MMCR is a great procedure if the patient has a positive neosynephrine test, good levator function, and they don’t have any conjunctival or corneal issues,” Andrew R. Harrison, MD, said during a presentation at Hawaiian Eye/Retina 2024.
Assessing levator function is essential when determining whether or not to perform MMCR.
“We're really not measuring the levator function per se — we're measuring the excursion of the eyelid and using that as our levator function number,” he said.
To properly measure levator function, ophthalmologists should brace the brow and then have the patient look up and down, Harrison explained. The excursion, measured in millimeters, will be the levator function.
Potential complications of MMCR include orbital hemorrhage, wound dehiscence, undercorrection, corneal abrasion, overcorrection and conjunctival scarring, Harrison said. Postoperative care for MMCR can include antibiotic drops at night, ice compresses followed by warm soaks and bandage contact lenses.
The advantages of transconjunctival surgery include lack of a cutaneous scar, the quick and predictable nature of the procedure and direct access to involved structures. One downside of transconjunctival surgery, Harrison explained, is that it is not quite as adaptable as levator surgery.
