Abstract Details

Purpose:

To determine the effectiveness of iridectomy, capsulotomy, and anterior vitrectomy with a 25 gauge vitreous cutter through the anterior chamber (AC) to treat the misdirection syndrome in nanophthalmic eyes.

Setting:

Non-comparative Case series at Hiroshima University Hospital

Methods:

Four consecutive patients with the nanophthalmic misdirection syndrome after successful cataract surgeries underwent capsulotomy and anterior-vitrectomy through a peripheral iridectomy from the anterior chamber. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), and anterior and posterior segment findings were recorded before and after the surgery.

Results:

A resolution of the aqueous misdirection was achieved in all cases. No recurrences except in one eye were observed after a mean follow-up of 42.4�Â�± 18.8 months (range, 21�â�€�“64 months). The mean IOP before the anterior vitreous and capsule surgery was 28.7 �Â�± 4.4 mmHg which was reduced to 13.7 �Â�± 1.3 mmHg at final visit. All but one patient who had uveal effusion maintained their BCVA. Scleral resection for uveal effusion and trabeculectomy for residual high IOP were useful.

Conclusions:

Iridectomy, lens capsulotomy, and anterior vitrectomy using 25 gauge vitreous cutters through the anterior chamber to create a communication between anterior and posterior chamber is an alternative option in the treatment of patients with nanophthalmic misdirection syndrome.
