Ocular manifestations of diabetes mellitus.

The ocular complications of diabetes mellitus are numerous and include retinopathy, cataract, uveitis, and neurophthalmic disorders. A review of the current literature shows that the emphasis has changed from the laser and surgical management of pre-existent retinopathy to the development of cohesive multidisciplinary screening and education programs, and to a better understanding of the cellular and molecular mechanisms that underlie disease. The role of associated and potentially modifiable systemic factors is also now recognized. Early intervention with systemic and local therapies may soon provide hope for the better management of diabetic eye disease.
