Abstract

PURPOSE
To report the case of a patient with ciliochoroidal detachment after brief exposure to patterned scanning laser photocoagulation.
CASE SUMMARY
We examined a 62-year-old woman with early proliferative diabetic retinopathy and observed neovascularization and macular edema upon fundus examination. The patient underwent patterned scanning laser photocoagulation with an exposure time of 0.03 sec over the entire retina in a single pass. In vivo, the ciliary body and choroid were examined using ultrasound biomicroscopy (UBM), before, immediately after, 3 and 7 days after panretinal photocoagulation. Ciliochoroidal detachment was observed 3 days after panretinal photocoagulation and spontaneously disappeared by 7 days after photocoagulation. The change in IOP coincident with ciliochoroidal detachment were not significant.
CONCLUSIONS
Ciliochoroidal detachment after panretinal photocoagulation may lead to complications such as angle-closure glaucoma. Patterned scanning laser photocoagulation with short exposure time should be practiced only with careful attention to the possible development of cilochoroidal detachment.

  Figure 1. Ultrasound biomicroscopy (UBM) images of the 62-year-old woman with proliferative diabetic retinopathy. (A) UBM before treatment. Ciliochoroidal area was intact. (B) UBM right after panretinal photocoagulation using patterned scanning laser. No specific change was seen compared to UBM before treatment. (C) 3 days after panretinal photocoagulation. Slit-like ciliochoroidal detachment appeared at pars plana (arrows). (D) 7 days after panretinal coagulation. Cilochoroidal detachment disappeared without any specific treatment for ciliochoroidal detachment.
