Scleral thinning after transcleral diode laser cycloablation.

Background and Objective: To highlight the occurrence of scleral thinning after transcleral diode laser cycloablation therapy.
Patients and Methods: A retrospective chart review was done of consecutive patients from the glaucoma and pediatric ophthalmology clinics of a tertiary eye care center in whom the presence of scleral thinning was noted after transcleral diode laser cycloablation therapy.
Results: Eleven eyes of 9 patients with various types of glaucoma (traumatic, congenital, juvenile, steroid induced, uveitic, and secondary angle closure) were found to have scleral thinning after undergoing transcleral diode laser cycloablation therapy for refractory glaucoma. Seven patients had undergone only 1 session before new scleral thinning was noted. Two patients had bilateral transcleral diode laser cycloablation therapy and subsequent bilateral thinning.
Conclusions: Scleral thinning may occur after diode laser cycloablation therapy even with only 1 treatment session and intact sclera, and young patients may be more susceptible to thinning.
