RESUMO
Scleral cyst is an unusual, rare clinical condition. Most of the cases reported have described the cyst to occur at the limbus, with or without involvement of the cornea. Posterior scleral cysts have seldom been reported in literature. This case report describes a postequatorial scleral cyst that may mimic a choroidal melanoma. Certain clinical features and swept-source optical coherence tomography are useful for elucidating the location of intraocular lesions anatomically, as well as distinguishing their structural characteristics.

Spectral domain optical coherence tomography (SD-OCT) is fast becoming the current standard of care for the detection and assessment of diabetic macular edema. With the application of SD-OCT for imaging of retinal microstructure and measurement of retinal thickness, new information regarding disease characteristics has been gathered, which was unrecognized previously. Retinal thickness measurements on SD-OCT have also been used for deciding the management and monitoring of the disease. Since its development, OCT has enhanced the understanding of retinal anatomical changes in diabetic retinopathy. Several authors have used SD-OCT to classify diabetic macular edema with the purpose of correlating the pathophysiology with disease severity. The classification systems have helped monitor the treatment efficacy and provide prognostic information on the treatment outcome. The following review article summarizes these classifications.
