[Argon laser iridotomy in neovascular glaucoma].

AIM: To evaluate the long term results of argon laser iridotomy in neovascular glaucoma with previous primary angle-closure glaucoma.

PATIENTS AND

METHODS

The study included 186 glaucomatouse eyes of 160 patients who had over a 10-year chronic primary angle-closure glaucoma. Inclusion criterion was later associated neovascular activities in the anterior globe segment, due to prolipherative diabetic retinopathy or central retinal vein occlusion. All the patients were treated with preparatory stretch burns of 200 u spot size, 0.2 sec. exposure and 200 mW power, and than with penetration burns of 50 u, 0.2 sec. and 1000 mW. until the transillumination appear.

RESULTS

The iris falls back and the peripheral anterior chamber deepens in 90% of the treated eyes.

CONCLUSION

Argon laser iridotomy is safely than any other method to deepen the anterior chamber when rubeosis of the iris is associated to primary angle--closure glaucoma.
