M. Roldanpallares et Th. Elbromboly, CONTRAST SENSITIVITY IN TREATMENT CONTROL OF CLINICALLY SIGNIFICANT DIABETIC MACULAR EDEMA, Annals of ophthalmology. Glaucoma, 29(6), 1997, pp. 357-361
The benefit of appropriate laser photocoagulation for clinically signi
ficant diabetic macular edema has been demonstrated hut treatment of c
ases with 20/20 visual acuity is not so clear. In a prospective trial
with 3 years' follow-up, changes in far contrast sensitivity were not
significant without clinically significant diabetic macular edema. Cha
nges in near contrast sensitivity showed similar findings by groups. O
nly treated cases improved with time in all spatial frequencies. Photo
coagulation of clinically significant diabetic macular edema and 20/20
visual acuity improves contrast sensitivity.
