OBJECTIVE To compare the size of subfoveal lesions based on photographic documentation before and after submacular surgery of choroidal neovascularization (CNV) lesions. METHODS Subfoveal lesion sizes at baseline and month 3 follow-up visits for patients assigned to surgery in the Submacular Surgery Trials (SST) Pilot Study were assessed categorically using Macular Photocoagulation Study (MPS) disc area (DA) circles. The Submacular Surgery Trials Pilot Study groups reviewed were as follows: Group N (age-related macular degeneration [AMD]; lesion <50% blood; classic CNV present; size < or =9 MPS DAs); Group R (AMD; prior nonfoveal laser; classic CNV present; size < or =9 MPS DAs); Group B (AMD; lesion > or =50% blood); and Group H (ocular histoplasmosis syndrome or idiopathic; classic CNV present; size < or =9 MPS DAs). RESULTS Postoperative month 3 lesion size was at least 1 size category smaller than the preoperative lesion size in 6% (4/66) of Group N, 0 (0/31) of Group R, 6% (2/34) of Group H, and 45% (18/40) of Group B eyes. In Group H eyes, there was no size change in 50% (17/34), and enlargement was found in 44% (15/34). For eyes in Groups N and R, approximately one third remained stable (20/66, 30% and 12/31, 39%, respectively), whereas two thirds enlarged by at least 1 category (42/66, 64% and 19/31, 61%, respectively). CONCLUSIONS The change in lesion size after submacular surgery was variable, with a tendency for Group H lesions to remain the same size or larger, Group B lesions to measure smaller, and Group N and Group R lesions to be larger.

UI MeSH Term Description Entries
D008266 Macula Lutea An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual Science, 4th ed) Lutea, Macula,Luteas, Macula,Macula Luteas
D008268 Macular Degeneration Degenerative changes in the RETINA usually of older adults which results in a loss of vision in the center of the visual field (the MACULA LUTEA) because of damage to the retina. It occurs in dry and wet forms.
