Show morePurpose:The presence of peripapillary intraretinal fluid (IRF) has a broad differential diagnosis, including several types of neovascular and pachychoroid-related diseases. However, the clinician may encounter cases without signs of neovascular or pachychoroid disease, or any other previously described diagnosis. For these patients, we propose the term NOn-Pachychoroid PEripapillary Schisis (NOPPES) of the retina, and we discuss the differential diagnosis.Design:A retrospective chart study set in a tertiary referral center for retinal diseases in Amsterdam, the Netherlands.Methods:Using multimodal imaging, cases suspected of peripapillary pachychoroid syndrome were reviewed. Cases without signs of neovascular or pachychoroid disease were included in this study. These cases were discussed in a group of senior retinal specialists to establish a diagnosis, and if there was no evidence for any previously described diagnostic entity, these cases were categorized as NOPPES.Results:Four cases of NOPPES were identified, 3 female patients and 1 male patient, aged between 58 and 75 years. Two patients were myopic, and 1 patient had a mild hyperopia. Three out of 4 cases showed unilateral peripapillary IRF, and 1 case had bilateral IRF. No improvement was seen after intravitreal bevacizumab or aflibercept, nepafenac eye drops, oral acetazolamide, vitrectomy with internal limiting membrane peeling, or surgery for carotid stenosis. One case showed a reduction in IRF after starting prednisolone eye drops.Conclusions:We describe NOPPES, a new form of peripapillary schisis-like IRF. NOPPES seems relatively therapy-resistant. More research is needed to delineate the clinical spectrum of NOPPES and its pathogenesis and treatment. Show less

Show morePurpose: To increase insight into the myopic presentation of central serous chorioretinopathy (CSC) by comparing a large group of myopic patients with CSC with reference groups with only one of the diagnoses. Methods: Myopic patients with CSC (spherical equivalent <=-3D, n = 46), emmetropic patients with CSC (spherical equivalent -0.5 to 0.5 D, n = 83), and myopic, non-CSC patients (n = 50) were included in this multicenter cross-sectional study. Disease characteristics and imaging parameters, such as subfoveal choroidal thickness and indocyanine green angiography patterns, were compared between cases and reference groups. Results: In myopic patients with CSC, median subfoveal choroidal thickness (286 mu m [IQR 226-372 mu m]) was significantly thicker than subfoveal choroidal thickness in myopic, non-CSC patients (200 mu m [IQR 152-228 mu m], P < 0.001) but thinner than emmetropic patients with CSC (452 mu m [IQR 342-538 mu m], P < 0.001). They also had pachyvessels in 70% of the eyes comparable with emmetropic CSC (76%, P = 0.70). Choroidal hyperpermeability was frequently present on indocyanine green angiography in both myopic and emmetropic CSC eyes. Need for treatment, treatment success, and recurrence rate were not significantly different between CSC groups. Conclusion: Myopic CSC presents with similar imaging and clinical characteristics as emmetropic CSC, apart from their thinner choroids. Keeping in mind the structural changes of myopia, other imaging characteristics could aid the diagnostic process. Show less
