Purpose:
To investigate the effects of subfoveal choroidal neovascularizzation (CNV) secondary to age-related macular degeneration (AMD) on macular functional parameters quantified with an automatic fundus perimeter.
Methods:
118 eyes of 98 consecutive patients with subfoveal CNV secondary to AMD were evaluated. Best corrected visual acuity (ETDRS charts), fundus photography, and fluorescein angiography were performed. Microperimetry (fundus-related perimetry) was used to quantify macular sensitivity and fixation pattern (location and stability).
Results:
Of 118 eyes: 26 (21.9%) had central, 18 (15.1%) poor central and 74 (63.0%) eccentric fixation; 31 (26.0%) had stable, 42 (35.6%) relatively unstable and 45 (38.4%) unstable fixation. In 75 eyes (63.4%) a dense central scotoma was found. Angiographic classification of subfoveal CNV (occult versus classic) was not significantly related to fixation pattern (location: P = 0.274; stability: P = 0.385), and presence of dense scotoma (P = 0.41).
Conclusion:
Microperimetric quantification of macular sensitivity and fixation pattern in eyes with subfoveal CNV secondary to AMD offers new data about the impact of visual impairment in these eyes. Moreover, microperimetry improves the functional evaluation of subfoveal CNV in AMD.
