ICT is associated with less progression of microvascular complications than intensive medical therapy. Multicenter, randomized trials are needed to further study the role of ICT in slowing the progression of diabetic complications.
SUMMARY Plaques of hard exudate measuring 0-5 to 10 disc diameters, which occurred in 5 eyes of 4 patients with diabetic maculopathy, showed complete organisation in 8 to 18 months with the formation of scars measuring 0-2 to 0 5 disc diameters. Spontaneous progression and regression of hard exudate in diabetic maculopathy was described by King et al.1 and Dobree,2 who found that plaque formation required years for resolution and was not followed by visual recovery. In a previous report3 we described the pathology of an organised macular plaque in exudative diabetic maculopathy and observed that the fibrous replacement was partly retinovascular and partly pigment epithelial in origin, suggesting that it was a specific pathological entity. The present study reports the resolution of mnacular plaques accompanied by organisation in 5 eyes of 4 patients with diabetic maculopathy. This late clinical appearance, which is fully described for the first time, may be the only ophthalmoscopic evidence that a severe exudative maculopathy has been primarily responsible for severe visual loss, and should be differentiated from disciform macular degeneration in older patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
