Four cases of hypotony maculopathy caused by traumatic cyclodialysis and treated by vitrectomy, cryotherapy, and gas tamponade.

PURPOSE: We report our results in four cases of hypotony maculopathy caused by traumatic cyclodialysis and treated by combined vitrectomy and cataract surgery.

METHODS

The patients' visual acuities ranged from light perception to 0.2, and intraocular pressures ranged from 4.7 to 5.7 mmHg (mean 5.1 mmHg) before surgery. Ultrasound biomicroscopy (UBM) revealed cyclodialysis associated with ciliary body detachment of 180 degrees to 360 degrees . We performed combined vitrectomy and cataract surgery, with pars plana cryopexy for detached ciliary body and an SF(6) gas tamponade.

RESULTS

Postoperative UBM showed that cyclodialysis and/or ciliary body detachment disappeared in the whole circumference of two eyes, while it partially remained at 15 degrees in one eye and at 30 degrees in one eye. Postoperative visual acuity ranged from 0.06 to 1.2, with IOP ranging from 9.0 to 14.7 mmHg (mean 12.2 mmHg).

CONCLUSIONS

Based on our results, we consider that the present combined therapy is highly reliable for closing and adhering traumatic cyclodialysis and normalizing hypotony.
