Macular edema is the final common pathway of many intraocular and systemic insults. It may develop in a diffuse pattern where the macula appears generally thickened or it may acquire the characteristic petaloid appearance referred to as cystoid macular edema.

This article provides the reader with practical information to be applied to the various remaining causes of macular edema. Some macular edemas linked to ocular diseases like radiotherapy after ocular melanomas remained of poor functional prognosis due to the primary disease.

Retinal edema is defined as any increase of water in retinal tissue resulting in an increase in its volume. This increase may be initially intracellular or extracellular. In the first case, there is cytotoxic edema. In the second, vasogenic edema, directly associated with an alteration of the blood-retinal barrier (BRB).

Photocoagulation by either the argon laser or xenon arc instruments has been reported to have a beneficial effect in selected patients with macular edema. Treatment is not effective in all cases; indeed, in some patients with perifoveal capillary closure, severe macular edema, long-standing organized hard exudates, or significant cystoid maculopathy ...

Diabetic macular edema (DME), defined as a retinal thickening involving or approaching the center of the macula, represents the most common cause of vision loss in patients affected by diabetes mellitus. In the last few years, many diagnostic tools have proven to be useful in the detection and the monitoring of the features characterizing DME.

Macular edema may be intracellular or extracellular. Intracellular accumulation of fluid (cytotoxic edema) is an alteration of the cellular ionic distribution. Extracellular accumulation of fluid is more frequent and clinically more relevant, and is directly associated with an alteration of the blood-retinal barrier.

Three patients with macular edema noted that their vision improved during the course of the day. In one patient, a 25-year-old man, visual acuity improved from 20/40 to 20/30; in the second, a 53-year-old woman, it improved from 20/60 to 20/40; in the third, a 30-year-old man, it improved from 20/25 to 20/20.

Pathophysiology of Macular Edema
Ophthalmologica, 2010Macular edema is defined as an accumulation of fluid in the outer plexiform layer and the inner nuclear layer as well as a swelling of Müller cells of the retina. It consists of a localized expansion of the retinal extracellular space (sometimes associated with the intracellular space) in the macular area. Macular edema is a common cause of a sudden or

Diabetic macular edema (DME) is one of the most common causes of visual loss in patients with diabetes mellitus. Many patients continue to lose vision despite laser photocoagulation and medical therapies. The two major categories of medications currently used to treat DME are corticosteroids and anti-VEGF agents.

General Pathophysiology of Macular Edema
European Journal of Ophthalmology, 2010Macular edema represents a common final pathway for many ocular diseases. Related ocular disorders include diabetic retinopathy, vascular occlusions, postsurgical situations, and uveitic diseases. The key pathophysiologic process is a breakdown of the blood-retinal barrier, normally preventing water movement in the retina, thus allowing fluid to ...
