(a) Colored fundus photography and (b) fundus autofluorescence images at the time of admission to our clinic. In addition, enhanced depth imaging (EDI)-OCT findings indicating (c) low-to-medium homogeneous reflective signals at the choroidal layer of the peripapillary region, in addition to smooth, anterior sloping of RPE with subretinal and intraretinal fluid particularly nasal to the OD. (d) Subretinal fluid and intraretinal retinoschisis-like cystoid edema at the macula extending toward the OD, along with elevated subfoveal choroidal thickness. (e) Non-central, isolated serous retinal detachment temporal to the macula.

There were centrally located focal RPE changes and orange pigmentation nasal to optic disk (OD) (Fig. 1). Subfoveal choroidal thickness (SFCT) was increased (523micro), indicating a pachychoroid spectrum (Fig. 1).
(a) Optical coherence tomography angiography revealed well-defined network of interconnected varying sized enlarged vessels (red arrow). (b) B-scan ultrasonography indicating a solid lesion with high internal reflectivity and (c) associated retinal detachment (RD) (tumor thickness was 2.8 mm, tumor + RD thickness was 3.5 mm).

OCTA revealed well-defined network of interconnected vessels (Fig. 2a). B-scan ultrasonography (USG) indicated an acoustically solid lesion with high internal reflectivity (tumor thickness=2.8 mm) and associated retinal detachment (total thickness=3.5 mm) (Fig. 2b and c).
(a-d) Fluorescein angiography showed early spotty and late diffuse, intense hyperfluorescence nasal to the OD, in addition to early hyperfluorescent spot with gradual enlargement in the late phases ("inkblot" pattern) at the temporal region of the macula. (b-f) Indocyanine green angiography indicated intense hyperfluorescence of choroidal vessels in the arterial phase with late staining nasal to the OD, along with choroidal hyperpermeability temporal to the fovea.

FA and indocyanine green angiography (ICGA) established the presence of CCH and accompanying CSCR which might have worsened with systemic steroid treatment (Fig. 3).
Six months after PDT (a) colored fundus photography, (b) B-scan ultrasonography showing tumor thickness reduced to 1.4 mm with resolved RD, and the presence of only retinoschisis over the OD. (c) OCT section demonstrating totally resolved subretinal and intraretinal fluid at the macula.

The tumor thickness was reduced to 1.4 mm associated with small retinoschisis area over the tumor at 6 months of follow-up (Fig. 4).
