Primary vitrectomy for pseudophakic and aphakic retinal detachments.

PURPOSE

To evaluate primary vitrectomy for the treatment of pseudophakic and aphakic retinal detachments. Primary vitrectomy may enable better identification of retinal breaks than scleral buckling procedures.

METHODS

A prospective study was performed of primary vitrectomy for the treatment of 25 consecutive cases of pseudophakic and aphakic retinal detachment.

RESULTS

The primary retinal reattachment rate was 84% (21 eyes). Surgical failure resulted from new/missed retinal breaks (2 eyes) and proliferative vitreoretinopathy (2 eyes). The final retinal reattachment rate with further surgery was 96% (24 eyes). There were 7 macula-on detachments which all retained their presenting visual acuity. A visual acuity of 6/18 or better was achieved by 56% of the 18 macula-off detachments. Visualisation of the peripheral retina was impaired in 17 eyes and procedures to improve visualisation were performed in 7 eyes. Retinal breaks were detected in 16 eyes at surgery that had not been identified pre-operatively. Raised intraocular pressure was the most common complication, affecting 10 eyes in the early post-operative period.

CONCLUSIONS

Primary vitrectomy offers certain advantages in the treatment of pseudophakic and aphakic retinal detachments. A controlled study is required to determine whether primary vitrectomy achieves a better outcome than scleral buckling procedures for these retinal detachments.
