ABSTRACT
The authors retrospectively investigated the long-term visual recovery in 32 macular reattached eyes that had been monitored for more than 5 years after surgery. The best corrected visual acuities were better at 5 years postoperatively than at 3 months by two lines or more in 17 eyes (53%). In these 17 eyes, visual acuities continued to improve for up to 10 years after surgery. In the other 15 eyes, the visual acuities remained within one line of the 3-month values. Improvement of the long-term postoperative visual acuity was found to be statistically correlated with younger age, no or mild myopia (>-5 diopters), and shorter duration of macular detachment (< or =30 days). Surgeons should be aware that the visual function of reattached retinas may continue to improve over the long term, especially when these beneficial factors are present.

We retrospectively investigated long-term visual recovery in 32 macular reattached eyes which had been followed up for more than five years after surgery. In 17 eyes (53%), the best-corrected visual acuity at 5 years after surgery was > or = 2 lines better than best-corrected visual acuity at 3 months postoperatively. For these 17 eyes, the mean visual acuity continued to improve for up to 10 years after surgery. In the other 15 eyes, visual acuity changes were within 1 line. Improvement of long-term postoperative visual acuity was found to be statistically correlated with younger age, no or mild myopia (< -5D) and shorter duration of macular detachment (< or = 30 days). Surgeons should be aware that the visual function of reattached retinas may recover in the long-term, especially in eyes with these features.

We developed a disposable electrode for the electroretinogram made of anomalous polyvinyl alcohol gel. This new hydrogel is a rubber-like elastic with water content 80-90 wt%, but insoluble in water. The elastic electrode plate is approximately 0.3-1.0 mm thick, sterile, flexible, and easily cut to the desired shape. Its low cost permits it to be discarded after use.
