A 27-year-old woman with mild myopia presented with blurred vision and photopsia of the right eye for 2 weeks. She had no particular medical or ocular histories.\nThe patient’s best-corrected visual acuity (BCVA) was 1.0 OD (oculus dexter) and 1.5 OS (oculus sinister). Relative afferent pupillary defect was negative. There were no abnormal ocular findings OS. Slit-lamp examination revealed no inflammation in the anterior chamber or vitreous. Funduscopic examination showed multiple, faint, subretinal white dots at the posterior pole to the equator and macular granular change (, arrowheads). In addition, retinal vascular sheathing was observed at the midperiphery (, arrows). Fluorescein angiography (FA) showed hyperfluorescence continuing from the initial phase corresponding to the white dots (, arrowheads) and the staining of the optic disk. The retinal sheathing sites showed vascular staining with leakages in the late-phase OD (, arrows). Indocyanine green angiography showed no abnormal appearance in the initial phase and multiple hypofluorescence at the wider area than the white dots (, arrowheads). Enhanced depth imaging optical coherence tomography (EDI-OCT) revealed the discontinuity of the ellipsoid zone at macular area OD (, arrows) and that the subfoveal choroidal thickness (SCT) was 295 µm. Humphrey perimetry (30-2 Swedish threshold interactive algorithm standard test) showed a mild blind spot enlargement OU (oculus uterque) (mean deviation [MD] value: −1.83 dB OD and −1.08 dB OS). Multifocal electroretinography (mfERG) showed entirely decreased amplitude, except normal central amplitude OD, and mildly decreased amplitude at the retinal site that corresponded to the peripapillary area OS. Infection screening, including tuberculosis, syphilis, human T-cell leukemia virus type 1, and toxoplasmosis, showed negative results on QuantiFERON and serological testing or with antibodies for these agents. The chest X-ray was normal and serum angiotensin-converting enzyme was within normal limit. The patient received a diagnosis of MEWDS OD and was followed up with no treatment. One month after the first visit, the white dots and retinal vascular sheathing spontaneously resolved. After 3 months, the ellipsoid zone at the macula restored and the SCT decreased to 237 µm, together with increased BCVA of 1.5 OD (). On Humphrey perimetry, the MD value improved to −0.28 dB OD and −0.69 dB OS.
A 48-year-old female presented to us with blurring and distortion of vision in OS since 2 weeks. Her BCVA was 6/6; N6 in OD and 6/24;N10 in OS at presentation. Fundus examination showed an extrafoveal CNVM. Based on multimodal imaging including SD-OCT and FFA, patient was diagnosed to have type-2 CNVM with subfoveal choroidal thickness of 505 μm. She was also treated with antiVEGF monotherapy on pro re nata (PRN) basis and had multiple recurrences over 5 years. Interestingly, she developed FCE at the site of resolved CNVM scar, during 23 months of treatment, which progressively increased from 85 μm to 154 μm in depth over the subsequent follow-ups. We report this as a case of acquired FCE secondary to CNVM [].
