Abstract

Purpose : To evaluate axial length (AL) measurements and refractive outcomes in vitrectomy combined with cataract operation for rhegmatogenous retinal detachment (RRD) with wholly detached macula.

Methods : A retrospective, consecutive, comparative, clinical study.
We reviewed the data of patients treated by vitrectomy combined with cataract operation for RRD. The group “Attach” (n=31) consisted of eyes in which retina was not detached within 1.5 disc diameters from the foveal center, and the group “Detach” (n=33) consisted of eyes in which those area was detached entirely. In the group “Detach”, only the eyes (n=20) which AL were measured similar to those fellow eyes were compared to the group “Attach” (n=31). Refractive shift (RS) was defined as the average of the difference between postoperative spherical equivalent (SE) and predicted SE.

Results : AL was well measured by A-scan ultrasonography (A-scan) in all 31 eyes of the group “Attach” and RS was minus 0.57 diopters (D). AL was measured by A-scan similar to its fellow eye in 20 of 33 eyes (60.6%) in the group “Detach”, and RS of 20 eyes was minus 0.09 D. The difference in RS (0.48 D, P=0.025) between groups was equivalent to the AL difference as much as macular thickness (about 300um)

Conclusions : When AL can be measure by A-scan similar to its fellow eye in RRD with wholly detached macula, RS would be smaller than that of the wholly attached macula after phacovitrectomy. It assumed that AL was measured from RPE under the detached macula in RRD with wholly detached macula.
