Cataract extraction as a means of treating postfiltration hypotony maculopathy.

Hypotony maculopathy may arise after glaucoma filtering surgery. This can be treated by inducing inflammation and scarring within the filter, with the aim of increasing intraocular pressure (IOP) and promoting resolution of maculopathy. Cataract extraction can promote such inflammation. Phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation was performed in two consecutive patients with postfiltration hypotony maculopathy and preexisting cataracts. After cataract extraction, improvement of IOP, visual acuity, maculopathy, and metamorphopsia occurred in both patients. Cataract extraction can be beneficial in the management of postfiltration hypotony maculopathy.

Corneal incision phacoemulsification and internal bleb revision.

BACKGROUND AND OBJECTIVE: Cataract extraction in filtered eyes often leads to decreased outflow and, eventually, to bleb failure. The authors describe a surgical technique that promotes preservation of the filtering bleb. PATIENTS AND METHODS: The authors retrospectively reviewed 19 eyes of 19 consecutive patients who underwent corneal incision phacoemulsification and simultaneous internal revision of the previous filtering bleb. RESULTS: The mean follow-up time was 13.6 +/- 7.6 months. Visual acuity improved in all patients (89.4 percent achieved 20/40 or better). No significant difference was noted between preoperative and postoperative intraocular pressures and astigmatism. The bleb was preserved in 89.4 percent of the eyes at the time of the last follow-up. CONCLUSIONS: This surgical technique proved to be safe and yielded good results.
