Diode laser trans-scleral cyclophotocoagulation in the management of glaucoma in patients with long-term intravitreal silicone oil.

摘要

We read with great interest the article by Sivagnanavel et al. We will be most grateful if the authors can help to clarify a few points.In this series, the authors described a significant number of subjects losing vision after trans-scleral cyclophotocoagulation (TSCPC). They felt that the loss was not quantifiable because of the poor visual acuity. They concluded that TSCPC failed to protect against visual loss in the long term. We may like to be aware that it is the natural course of their disease to lose vision. Hence, they may like to compare with the rate of visual loss in the TSCPC-treated group with a control group having similar glaucoma associated with long-term silicone oil placement, and who were treated with other modalities. It may be of interest for the authors to attempt quantification with Logmar (Logarithm of Minimum Angle of Resolution) chart, or express the percentage of eyes losing 2 or more lines.
