Neodymium-YAG Laser Therapy for Iris Cysts

Arch Ophthalmol. 1986;104(8):1130-1134. doi:10.1001/archopht.1986.01050200036033

To the Editor.  —Spontaneously occurring cysts of the iris not derived from epithelial ingrowth are occasionally observed in clinical practice. Patients usually remain symptom free, but if the cysts enlarge to a sufficient size, they can produce a secondary chronic or acute angle closure glaucoma, compress the iris against the corneal endothelium causing corneal decompensation and/or an inflammatory reaction in the anterior segment of the eye, or obstruct the visual axis.1Many techniques have been previously advocated for treatment of iris cysts. Recommended therapies range from invasive surgical techniques to argon laser penetration of the cysts.1,2 Up to this point, the use of the neodymium-YAG laser has rarely been discussed for the use of iris cyst puncture.3 This case report documents our use of a Q-switched neodymium-YAG laser in the management of a patient with an iris cyst which partially blocked the visual field.
