| Abstract: | Flourescein angiography has been proved to be of value in the study of the chorioretinal abnormaliteis in sector retinitis pigmentosa. The findings from two patients, one being in an early and the other in a more advanced stage were analyzed. The pigment epithelium was found to be disturbed in a larger area than visible by ophthalmoscopy. In the impaired quadrant the retinal vessels were narrowed showing delayed and slow dye transit. Through the discolorated pigment epithelium leaky choriocapillaries were disclosed. Moreover, in the severly affected patient, areas missing choriocapillar perfusion and retinal circulation were also detected. |
