[The application of retinotomy and retinectomy for complicated retinal detachment].

OBJECTIVE

To investigate the techniques, therapeutic effects, indications, complications and control of retinotomy and retinectomy for complicated retinal detachment.

METHODS

Based on the preliminary report of retinotomy and retinectomy, 36 eyes of 36 patients of complicated retinal detachment were operated on and followed-up for 3-12 months. The operative technique included buckling, vitrectomy, peeling, retinotomy and retinectomy, intraocular tamponade and laser treatment.

RESULTS

Retina was reattached in 32 eyes in operation. Retinal detachment was recurrent in 8 eyes in followed-up in which retina was reattached again in 3 eyes by second operation. The last successful rate was 75% (in 27 eyes). The visual acuity was worse than funger conter in 33 eyes and worse than 0.05 in 3 eyes before operation. The visual acuity was better than 0.05 in 20 eyes (55.5%) after operation. The complications included bleeding, retinotomy expanding, complicated cataract, hypotony and so on.

CONCLUSION

Retinotomy and retinectomy can improve the curative effect of complicated retinal detachment. But the complications of these operation were severe. The indications should be well controlled.
