ABSTRACT
A known diabetic patient presented with diabetic macular edema (DME) and nonproliferative diabetic retinopathy in both eyes with a vision of 6/18, N12in the right eye and 4/60, N36in the left eye (LE). The patient had undergone injection of dexamethasone implant in the LE which got misdirected into the crystalline lens. The patient was taken up for phacoemulsification with intraocular lens implantation along with vitrectomy and posterior vitreous detachment induction, and redirection of the dexamethasone implant into the vitreous cavity. The DME resolved over the next 3 months
ABSTRACT
Diabetic retinopathy (DR) is a well-known risk factor in the development of radiation maculopathy (RM). Steroids have been shown to improve the vision and reduce the macular thickness in patients with RM. This observational case report highlights altered course of DR after a course of radiotherapy for orbital lymphoma, after a single dose of intravitreal dexamethasone implant showed a dramatic revascularization of the ischemic macula, with a significant reduction in the size of ischemic area. This appears to be the first case in literature corroborating the favorable effect on steroids on retinal vasculature, seen angiographically.
ABSTRACT
Diabetic macular edema (DME) is a common reason for vision decrease.The concept of DME treatment regime has been changed to increase the vision-sight of patients since the onset of new treatment.Recent DME guidelines introduced the latest researches of DME,which raised new clinical suggestion and clinical pathway based on evidence-based medicine.Anti-vascular endothelial growth factor (VEGF) treatment is the first-line therapy for all types of DME,laser photocoagulation and intravitreal steroid injection are often the supplementary treatment except for some special cases in which they can be the substitution for anti-VEGF treatment.The regime for DME treatment now is combination.To understand and follow the guidelines can help us instruct and standardize our management on DME.
