Abstract Details

Purpose:

As not every macular lesion noted on fundus examination or OCT is clinically significant, the authors explored the utility of microperimetry in the evaluation of the macular dysfunction in cataract patients, to aid in proper IOL selection (multifocal vs monofocal) and to set expectations for post-operative visual function.

Setting:

Ophthalmic Consultants of Long Island, Rockville Center, NY, USA

Methods:

In this pilot study, one randomly chosen eye of 10 patients from the patient population of the Ophthalmology Consultants of Long Island diagnosed with mild (1+) to moderate (3+) cataract was evaluated before and 1 week after cataract surgery with the MAIA microperimeter (Centervue S.p.A, Padova, Italy). Best corrected visual acuity for distance (BCVA), dilated and undilated biomicroscopy and indirect fundus examinations, IOP measurement and a MAIA microperimeter test to measure macular sensitivity and fixation pattern were also performed.

Results:

In this 10 eye cohort, two patients showed macular abnormalities before and after surgery that were noted on MAIA testing: one of them showed reduced average threshold sensitivity and abnormal percent reduced threshold, while the other patient showed fixation drift demonstrating eccentric fixation. Both eyes had reduced post-operative visual performance after uneventful cataract surgeries.

Conclusions:

As not every macular lesion noted on fundus examination or OCT is clinically significant, microperimetry can be useful to detect clinically significant retinal dysfunction prior to cataract surgery. The outcome may aid in the selection of IOL type and may yield a better documented surgical prognosis. Further studies are necessary to confirm these findings.
