Abstract
Background:
The question addressed is: how does the postoperative visual acuity in eyes
treated with segmental buckling compare over time with the paired fellow
eyes ?
Methods:
107 detachments were followed prospectively for 15 years. The eyes were
divided into: group I, macula attached (46); group II, macula partially
detached (10); group III, macula completely detached (51). Mean preoperative
visual acuity was 20/30 in group I, 20/100 in group II, and 20/400 in group
III. The operation consisted of segmental buckling without drainage. No
eye had cerclage or vitrectomy.
Results:
The retina remained attached in 99 eyes during the 15year followup. The
mean visual acuity of all patients improved six months postoperatively to
20/40 with a maximum of 20/30 at one year. Thereafter there was a linear
decrease in all three groups.
Conclusions:
Visual acuity improved during the first year, followed by a linear decrease
of 0.07 line/year. The paired eyes decreased similarly in relation to age.
There was no real difference in the visual acuity of the operated and unoperated
eyes (P=0.079) during the 15 years of followup. Mean visual acuity was 20/40
in the operated eyes of 72 patients who were living after 15 years. These
data present a challenge to those surgeons who use techniques that include
encircling the eye to review and compare their longterm visual results.
