ABSTRACT
AIM:
To observe the multimodal image features of dome-shaped macula(DSM)with subretinal fluid(SRF)in adolescents with high myopia, and investigate its typical features and identification methods.METHODS:
This is a retrospective study. A total of 21 adolescent patients(39 eyes)who were diagnosed as DSM in high myopic eyes with SRF in the macula area in our hospital from January 2021 to May 2022 were selected. All patients underwent color fundus photography(CFP), fundus autofluorescence(FAF), spectral-domain optical coherence tomography(SD-OCT), optical coherence tomography angiography(OCTA)and electro oculography(EOG). Among them, 18 patients(36 eyes)underwent fundus fluorescein angiography(FFA), and they were followed-up for 12mo to record the change of the central macular thickness(CMT).RESULTS:
Fundus examination showed tessellated retina in affected eyes, and the deposition of granular material could be seen in the fovea of the macular area. SD-OCT showed a dome-like bulge of the whole layer in the macular area, localized detachment of the subfoveal nerve epithelial layer, the medium and high reflection attachment on the inner surface of the outer membrane, and the heterogeneous reflection of the retinal pigment epithelium(RPE)layer. FAF showed a mild “bull's eye sign” change in the macular area. FFA showed granular transmitted fluorescence around the foveal avascular zone. En face of OCTA could see a clear boundary of the neuroepithelial detachment zone. When the tangential line corresponds to the ellipsoid zone-RPE layer, the granular high reflection in different sizes scattered in the neuroepithelial detachment zone could be seen, and no obvious choroidal neovascularization(CNV)was formed. During the follow-up of OCTA, SRF in the macular area can be spontaneously increased or absorbed irregularly. EOG indicates that the ratio of light peak to dark trough(LP/DT, i.e. Arden ratio)was normal, with an Arden ratio>1.55. CMT at 1, 3, 6, 12mo(247.10±13.03, 246.62±12.23, 248.05±14.00, 247.92±11.66 μm)during follow-up period were compared with baseline(246.95±11.46 μm), and the difference was not statistically significant(F=0.144, P=0.965).CONCLUSION:
Multimodal imaging is helpful in the clinical diagnosis of DSM with SRF in the macula area in high myopic eyes of adolescents, and plays an important role in the differential diagnosis of the early stage of typical Best disease.
