PERIPAPILLARY PACHYCHOROID SYNDROME New Insights

Purpose: Available literature on peripapillary pachychoroid syndrome (PPS) is very limited. The purpose of this study is to evaluate features of PPS using multimodal imaging and shed further light on this entity. Methods: This is a retrospective case series at a tertiary eye-care center. Patients with features of pachychoroid with preferential choroidal thickening in nasal macula along with pachyvessels were identified and included for analysis. The patients underwent fundus photography, fundus autofluorescence, optical coherence tomography, fundus fluorescein angiography, and indocyanine angiography. Images were separately analyzed by two different retina specialists. Results: A total of 27 eyes of 14 patients with mean age of 52.2 years were included. Seven patients had bilateral PPS, whereas six had unilateral; one patient had only one seeing eye. A total of 21 eyes with PPS were studied. 52.4% of the eyes revealed retinal pigment epithelium gravitational tracks, outer retinal atrophy, and serous PEDs. None of the eyes showed choroidal folds. Fundus fluorescein angiography showed late leakage at macula in 33% eyes. Fundus autofluorescence showed features of PPS to be similar to central serous chorioretinopathy in most cases. Conclusion: Peripapillary pachychoroid syndrome shares common findings with central serous chorioretinopathy and seems to be a subset of central serous chorioretinopathy than a separate entity in pachychoroid disease spectrum.

Automated summary

This study aims to evaluate the features of peripapillary pachychoroid syndrome (PPS) using multimodal imaging and further understand this entity. The results show that PPS shares common findings with central serous chorioretinopathy and may be a subset within the pachychoroid disease spectrum.
