Amniotic membrane "may cause strabismus complications"

Amniotic membranes used to prevent postoperative adhesions in strabismus eye surgery may actually be having the opposite effect, according to new research.

A study published in the Journal of AAPOS, the official publication of the American Association of Pediatric Ophthalmology and Strabismus, found that one patient had "extensive" adhesions and inelastic, fibrotic muscles.

This is despite previous research suggesting that the use of amniotic membranes can help to prevent scarring, said Dr Rehab Kassem, a researcher at Cairo University, where the study was carried out.

Dr David Hunter, editor-in-chief of the Journal of AAPOS, commented: "While this material may have been used successfully in other parts of the eye, strabismus surgeons should only consider using it around extraocular muscles in cases where there is already extreme scarring."

Meanwhile, according to a study carried out by Rensselaer Polytechnic Institute in Troy, New York, liquids known as ferrofluids could potentially help to improve people"s vision by being used in adaptive lenses.
