Abstract
Background
Patients presenting with macula-off rhegmatogenous retinal detachment (RRD) with concomitant age-related macular degeneration (AMD) and their treating physicians would benefit from knowledge regarding the visual prognosis after repair. The prognosis for such patients is not well known. The purpose of this study is to compare visual outcomes in macula-off RRD in eyes with AMD versus a group of comparison eyes without AMD.
Methods
This was a retrospective chart review of 1,149 patients. A total of 191 eyes met study criteria, 162 non-AMD eyes (controls) and 29 AMD eyes. The main outcome measure was postoperative visual acuity in control eyes versus AMD eyes, and this was compared using Fisher’s exact test.
Results
There was a statistically significant difference in postoperative visual acuity by AMD status, with those without AMD having a higher frequency of Count Fingers (CF), Hand Motion (HM), Light Perception (LP), or No Light Perception (NLP) vision (p = 0.023). More specifically 5.56% of non-AMD eyes and 3.45% of AMD eyes were 20/40 or better, 77.16% of non-AMD and 55.17% of AMD eyes were worse than 20/40 and better than 20/200, 10.49% of non-AMD eyes and 37.93% of AMD eyes were 20/200 or worse, and there were 11 eyes in the non-AMD group with CF, HM, LP, or NLP vision while there was only 1 eye in the AMD group with CF vision.
Conclusions
Though postoperative visual acuity was worse in the non-AMD group with a higher frequency of patients having final vision of CF, HM, LP, or NLP, this is not likely a clinically significant finding. Rather, it is a function of the difference in sample size and composition between the two groups. Importantly, this study suggests AMD patients can expect similar outcomes to non-AMD patients after RRD repair. Our study suggests that approximately 58% of patients with AMD can expect to maintain functional vision better than 20/200. We conclude that AMD patients can achieve functional vision after RRD surgery, similar to those without AMD. These findings may be helpful in guiding realistic expectations of AMD patients with RRD.
