PURPOSE:: To investigate retinal sensitivity (Se) in dome-shaped macula (DSM) using microperimetry and to correlate functional findings to specific spectral domain optical coherence tomography features. METHODS:: Patients affected by DSM in at least 1 eye were consecutively enrolled in a prospective, cross-sectional study. All studied eyes performed best-corrected visual acuity measurement, microperimetry to assess Se and optical coherence tomography to investigate DSM pattern and to measure bulge height and retinal and choroidal thicknesses. RESULTS:: Fifty-three eyes of 29 patients were studied. Dome-shaped macula was vertically oriented (V-DSM) in 23 (43.4%), symmetric (S-DSM) in 17 (32.1%), and horizontally oriented (H-DSM) in 13 eyes (24.5%). Foveal subretinal fluid was present in 29/53 (54.7%) cases; it correlated to the bulge height (P < 0.0001) and determined a reduction of Se (P < 0.0001) not of best-corrected visual acuity (P = 0.7105). Mean Se was 13.9 ± 3.2 dB. Microperimetry parameters did not differ among the different DSM patterns. However, Se was significantly impaired if foveal subretinal fluid was present in V-DSM and in S-DSM, but not in H-DSM (V-DSM: P < 0.0001; S-DSM: P = 0.0252; H-DSM: P = 0.5723). In H-DSM, inferior choroidal thickness was thicker in cases with foveal subretinal fluid compared with those without it (P = 0.0363). CONCLUSION:: In DSM, Se evaluation better reflects the central functional impairment than best-corrected visual acuity, particularly when some optical coherence tomography features, such as foveal subretinal fluid and higher bulge height, are present.

Abstract

PURPOSE:: To investigate retinal sensitivity (Se) in dome-shaped macula (DSM) using microperimetry and to correlate functional findings to specific spectral domain optical coherence tomography features. METHODS:: Patients affected by DSM in at least 1 eye were consecutively enrolled in a prospective, cross-sectional study. All studied eyes performed best-corrected visual acuity measurement, microperimetry to assess Se and optical coherence tomography to investigate DSM pattern and to measure bulge height and retinal and choroidal thicknesses. RESULTS:: Fifty-three eyes of 29 patients were studied. Dome-shaped macula was vertically oriented (V-DSM) in 23 (43.4%), symmetric (S-DSM) in 17 (32.1%), and horizontally oriented (H-DSM) in 13 eyes (24.5%). Foveal subretinal fluid was present in 29/53 (54.7%) cases; it correlated to the bulge height (P < 0.0001) and determined a reduction of Se (P < 0.0001) not of best-corrected visual acuity (P = 0.7105). Mean Se was 13.9 ± 3.2 dB. Microperimetry parameters did not differ among the different DSM patterns. However, Se was significantly impaired if foveal subretinal fluid was present in V-DSM and in S-DSM, but not in H-DSM (V-DSM: P < 0.0001; S-DSM: P = 0.0252; H-DSM: P = 0.5723). In H-DSM, inferior choroidal thickness was thicker in cases with foveal subretinal fluid compared with those without it (P = 0.0363). CONCLUSION:: In DSM, Se evaluation better reflects the central functional impairment than best-corrected visual acuity, particularly when some optical coherence tomography features, such as foveal subretinal fluid and higher bulge height, are present.
