Purpose : The ability of current methods such as the potential acuity meter to predict best corrected visual acuity (BCVA) after cataract surgery in patients with concomitant macular disease is controversial. The purpose of this study is to compare BCVA with foveal sensitivity by Humphrey visual field in patients with macular degeneration.

Methods : Retrospective chart review of patients with a diagnosis of macular degeneration and pseudophakia having performed a Humphrey visual field. 147 eyes of 95 patients were found to meet the inclusion criteria. The average age of participants was 81.8 years. 64% of subjects were female and 36% were male. Visual field indices as well as clinical information about macular degeneration and other causes of vision loss were collected. Initially, post-operative BCVA was compared with post-operative foveal sensitivity, to establish a correlation between these data sets. In a small subset of patients who had a pre-operative Humphrey visual field, the pre-operative foveal sensitivity and post-operative BCVA were compared. Pearson correlation coefficients were calculated to determine correlation between logMAR BCVA and foveal sensitivity.

Results : There was a statistically significant correlation between post-operative logMAR BCVA and post-operative foveal sensitivity in this population. This correlation remained statistically significant upon sub-analysis of patients with dry macular degeneration and wet macular degeneration. Additionally there was a correlation between pre-operative foveal sensitivity and post-operative logMAR BCVA that was also statistically significant. Table 1 depicts the Pearson correlation coefficient for these groups.

Conclusions : Foveal sensitivity is correlated with BCVA in pseudophakic patients with macular degeneration. These findings support the hypothesis that foveal sensitivity could be used as a predictor of post-operative BCVA.
