The Use of Intravitreal Injection of Triamcinolone Acetonide in Diabetic Patients to Reduce Diabetic Macular Edema

INTERVENTION: Nineteen patients with bilateral diabetic macular edema were included, one eye for every patient underwent intravitreal injection of 4mg triamcinolone acetonide (group A, 19 eyes) and the other eye of the same patient underwent intravitreal injection of 8mg triamcinolone acetonide (group B, 19 eyes), the selection of which eye to receive either dose was random. The patients were followed up for six months after injection , complete Ophthalmological examination and optical coherent topography were done. CONDITION: Diabetic macular edema PRIMARY OUTCOME: control of diabetic macular edema (DME), detection of DME was done with Optical Coherence Tomography.( medical Equipment) SECONDARY OUTCOME: follow up of intraocular pressure (IOP) rise after injection. measurement was done by Goldmann applanation Tonometer mounted on slit lamp.. ; INCLUSION CRITERIA: The major eligibility criteria for the study eyes included the following: (1) best‐corrected visual acuity letter score between 20/40 and 20/320; (2) definite retinal thickening resulting from DME on clinical examination involving the center of the macula assessed to be the main cause of visual loss; (3) retinal thickness measured with optical coherence tomography (OCT) of 250 micro m or more in the central subfield ;(4) Grid laser treatment was done at least three months earlier.
