Ocular hypotony secondary to cyclodialysis leads to functional and anatomic changes that may result in irreversible visual acuity loss. Four consecutive cases with hypotony, following trauma, are described. Three cases were treated with argon laser photocoagulation to the sclera, ciliary body and iris root. The parameters used for the laser treatment were 100 μm spot, 0.2s of exposure time and power varying from 1.0 to 1.2 W in up to two sessions. One of the four cases underwent direct cyclopexy, the ciliary body being sutured to sclera. They all showed closure of the cleft and intraocular pressures between 13 and 18 mmHg. The authors conclude that ocular hypotony secondary to cyclodialysis may be successfully treated with argon laser photocoagulation or, in refractory cases, by performing direct cyclopexy associated or not to laser treatment.
