Longitudinal follow-up of dome-shaped macula.

Abstract

Background/objectivesTo determine if the presence of sub-retinal fluid (SRF) was associated with reduced vision in dome-shaped macula (DSM), and to assess its effect and response to treatment during follow-up.MethodsPatients were identified retrospectively. Baseline and follow-up data were recorded. The diagnosis of DSM, and presence or absence of SRF and intra-retinal fluid (IRF) was confirmed using Spectral Domain-Optical Coherence Tomography (SD-OCT). Decisions to treat oedema were based on clinician preference.Results193 eyes of 106 patients (71 female) were confirmed to have DSM. Overall mean duration of follow-up for this cohort was 3.5 years. Mean BRVA for all eyes at baseline was 0.38 (range: −0.20 to ‘light perception’). A significant difference was noted in mean baseline BRVA between those eyes with SRF compared with those without SRF at baseline (0.48 vs. 0.31, p < 0.001). Intra-retinal fluid moderately correlated with poorer baseline BRVA (r = 0.31, p < 0.003). No significant change in BRVA was noted during follow-up. No significant effect of treatment on BRVA was observed.ConclusionsThe presence of SRF at baseline was associated with poorer vision. Vision appears to remain stable irrespective of the presence or absence of SRF at baseline. The treatments administered in this cohort did not affect final vision or SRF.
