Brief Summary

Intravitreal triamcinolone acetonide is a well-known method of treatment of diabetic macular edema, however, it has many side effects, most commonly causing cataract and glaucoma. Suprachoroidal route is an emerging route of delivery of intraocular drugs. This is to our knowledge the first prospective study to compare the effect of triamcinolone acetonide delivered via the intravitreal versus the suprachoroidal route in the treatment of diabetic macular edema as regards safety and efficacy.

Study Arms (3)

Study group I : Intravitreal injection

ACTIVE COMPARATOR

A single intravitreal injection of 0.1 ml triamcinolone acetonide in a concentration of 4 mg / 0.1 ml.

Procedure: Intravitreal injection (4mg/0.1ml)

Study group II: Suprachoroidal injection of full dose

ACTIVE COMPARATOR

A single suprachoroidal injection of 0.1 ml triamcinolone acetonide in a concentration of 4 mg / 0.1 ml.

Procedure: Superachoroidal injection (4 mg/0.1ml)

Study group III : Suprachoroidal injection of half dose

ACTIVE COMPARATOR

They will receive a single suprachoroidal injection of 0.1 ml triamcinolone acetonide in a concentration of 2 mg / 0.1 ml.

Procedure: Suprachoroidal injection (2mg/0.1ml)

Interventions

Injection will be performed in the operating room under complete sterile conditions Under topical anaesthesia. Intravitreal injection (4mg/0.1ml) of triamicinolone acetonide will be done using a 30-31 gauge needle at a distance of 3.5 mm from the limbus in aphakic or pseudophakic patients, and 4 mm in phakic patients. The needle will be then removed with application of cotton tipped applicator over the entry site. -IOP monitoring will be done at 15, 30 and 60 minutes following injection in all groups.

Study group I : Intravitreal injection

Injection will be performed in the operating room under complete sterile conditions Under topical anaesthesia. Suprachoroidal injection (4mg/0.1ml) of triamcinolone acetonide will be done using a custom-made 30-31 gauge needle with a sleeve to prevent further penetration of the needle into the vitreous cavity. Injection will be done at approximately 4 mm from the limbus. * IOP monitoring will be done at 15, 30 and 60 minutes following injection in all groups. * UBM assessment will be done 24 hours following injection to confirm targeting of the suprachoroidal space.

Study group II: Suprachoroidal injection of full dose

njection will be performed in the operating room under complete sterile conditions Under topical anaesthesia. Suprachoroidal injection (2mg/0.1ml) of triamcinolone acetonide will be done using a custom-made 30-31 gauge needle with a sleeve to prevent further penetration of the needle into the vitreous cavity. Injection will be done at approximately 4 mm from the limbus. * IOP monitoring will be done at 15, 30 and 60 minutes following injection in all groups. * UBM assessment will be done 24 hours following injection to confirm targeting of the suprachoroidal space.

Study group III : Suprachoroidal injection of half dose
