Purpose To describe the case of a woman who developed persistent subretinal fluid in the macular region after the placement of encircling band for retinal detachment surgery, possibly due to vortex vein compression. Methods Case report. Results A 66-year-old woman diagnosed with central serous retinopathy presented with poor vision and metamorphopsia in the left eye (LE). Her visual acuity had deteriorated to 20/100 in LE after retinal detachment surgery with scleral buckling 8 months before. Multimodal imaging including fundus autofluorescence and fluorescein angiography disclosed a gravitational hyperfluorescent area involving the macular region that appeared to originate from the superotemporal quadrant in correspondence with the buckling. This area corresponded to a serous retinal detachment on structural spectral-domain optical coherence tomography (SD-OCT). Interestingly, on indocyanine green angiography, the encircling band of the scleral buckling appeared located at the emergence of the superotemporal vortex vein. Based on these findings, the patient was diagnosed with gravitational serous retinal detachment secondary to vortex vein compression. Successful rapid visual recovery and decrease of retinal fluid on SD-OCT was achieved with prompt surgery of scleral buckling removal, confirming the diagnosis. Conclusions Choroidal veins can be obliterated during retinal detachment surgery, especially when retinal breaks are posterior to the equator. Indocyanine green angiography is the gold standard to study choroidal circulation and in our case allowed us to visualize the compression of the superotemporal vortex vein at the site of scleral buckling.

Dome-shaped macula (DSM) is an entity recently described as a convex anterior protrusion of the macular area within a posterior myopic staphyloma. Specific complications were associated with DSM, like serous retinal detachment (SRD). We describe a woman presenting with a decreased vision at 20/50. SD-OCT scans were performed, showing a macular bulge. SRD was present and an epiretinal membrane could also be observed. Fluorescein angiography and indocyanin green angiography did not show any leakage nor choroidal neovascularization. Epiretinal membrane peeling was performed, and 3 months after surgery, SRD completely disappeared. However, SRD reappeared 1 year after surgery and enlarged within 2 years following surgery. In conclusion, two mechanisms could be considered for physiopathology of SRD: first, the epiretinal membrane may have exerted traction on the macular retina, second, vitreous body might constitute a tank for cytokines and/or other factors, triggering subretinal fluid accumulation, leading to SRD.

A 66-years-old Vietnamese healthy female patient presented with prolonged severe right ocular pain and complete vision loss in that eye. Anterior segment assessment including gonioscopy identified angle-closure configuration. A suspected ciliary body melanoma was seen through the pupil. Posterior segment examination revealed a large tumor mass and 360° retinal detachment (kissing configuration). An ultrasound examination was consistent with a uveal tumor. The painful, blind right eye with a tumor mass was enucleated. Histopathology confirmed a type A uveal spindle cell melanoma associated with total serous retinal detachment without evidence of tumor necrosis, epithelioid cells, scleral, or optic nerve infiltration. There was no evidence of metastasis after 1-year of follow-up. It is critically important to differentiate primary and secondary angle closure, especially in cases with life-threatening ocular malignancy as uveal melanoma.
