Long-term natural history of highly myopic eyes with a dome-shaped macula with or without untreated serous retinal detachment: a 4-year follow-up study

PurposeTo evaluate the long-term functional and morphological changes occurring in myopic eyes with a dome-shaped macula (DSM), with or without untreated serous retinal detachment (SRD).MethodsThis prospective, single-centre study enrolled consecutive cases of highly myopic patients with DSM with or without a SRD. Patients underwent complete ophthalmological examinations, optical coherence tomography, axial length measurements and autofluorescence. Follow-up visits were performed with a maximum interval of 6 months for 4 years. Eyes with choroidal neovascularisation were excluded.ResultsTwenty-six eyes from 18 patients (mean age 61.2) were included. At baseline, 13 eyes had SRD and 13 did not. The DSMs were either horizontal (69%) or round (31%). There were no significant differences in best-corrected visual acuity (BCVA) between eyes with and without SRD during the 48-month follow-up period. Multivariate analysis showed that baseline BCVA was the only parameter among those analysed (age and SRD height) to have a significant effect on the final BCVA (pConclusionsBCVA remained clinically stable over 4 years without treatment despite the fluctuations and persistence of the SRDs.
