macular oedema

Retinal thickening due to the accumulation of fluid, which occurs in diabetic retinopathy, visualised by a binocular slit lamp or stereoscopic fundus photography. While macular oedema has few visual consequences, other than distortion of central vision, it is often accompanied by hard exudates, which are associated with loss of vision.

Laser photocoagulation may be used to manage branch retinal vein occlusion (BRVO); it is ineffective for central retinal vein occlusion (CRVO).

oedema, cystoid macular (CMO) 

Oedema and cyst formation of the macular area of the retina. It may occur as a result of, or be associated with, systemic vascular disease, retinal vein occlusion, diabetic retinopathy, uveitis, hypertensive retinopathy, retinitis pigmentosa and following some ocular surgery such as vitreoretinal, photocoagulation, glaucoma procedures and especially cataract surgery. When cystoid macular oedema follows cataract surgery it is called the Irvine-Gass syndrome and it is sometimes accompanied by intraoperative vitreous loss or vitreous adhesion to the iris or to the corneoscleral wound. Visual acuity is affected initially but recovers in the majority of cases. In some cases antiinflammatory therapy may help in restoring visual acuity and in other cases the vitreous adhesion may be disrupted with a Nd-Yag laser.

The Optina trial, conducted at St Michael Hospital in Canada, was a phase II, placebo-controlled, double-masked study to evaluate the efficacy and safety of a 12-week treatment with oral Optina in adult patients with Diabetic Macular Oedema.
As a criterion, all the patients included in the study were to have a confirmed diagnosis of diabetic retinopathy with a supportive clinical and angiographic evidence of diffuse or focal macular oedema. Patients who were found to have coexisting eye diseases that could also be a cause of visual impairment did not qualify to be included in the study.
The study was double masked and included 32 patients with moderate to severe diabetic macular oedema (range 316-707microns) that were treated orally with either placebo or one of three doses of Optina.
In this study all patients ahd macular oedema. FFA of these patients showed hyper-fluorescence in the macular area.
