Risk factors influencing the treatment outcome in diabetic macular oedema.

ABSTRACT

A multivariate analysis was done on 96 eyes to evaluate the effect of various risk factors on the final visual outcome after laser photocoagulation for clinically significant macular oedema (CSME) in diabetic retinopathy. Advanced age of the patient, large size of CSME and poor baseline visual acuity were found to be significantly associated with poorer outcome (p < 0.05). The association of nephropathy and hypertension with poorer visual outcome was of boderline significance (p = 0.054 and 0.07, respectively). Wavelength of the laser (argon or krypton) used for treatment did not significantly influence the outcome.
