Abstract
- Diode laser photocoagulation was performed in the pigmented rabbits, after intravenous administration of the Indocyanine green(4mg/kg). Exposure time and spot size were fixed at 0.2 second and 200um, and laser power varied in the range of 200-250mW to achieve gray-white burn. Ophthalmoscopic examination 1 hour later revealed that whitish photocoagulated lesion appeared somewhat larger in the ICG- administrated group than in the control. Depigmented border of the lesion appeared more distinct in the ICG- administrated group than in the control at 1 week later. There was no distinct difference between both groups at 1 month later. Histopathologically, degree of retinal damage was similar in both groups, but occlusion of choriocapillaris was more severe in the ICG- administrated group than in the control.
