All injections were performed in the operating room. The standard injection technique applied to all patients is as follows: Eyelids and around the eyes were wiped with a 10% sterile gauze pad impregnated with povidone-iodine. Proparacaine hydrochloride (Alcaine) was dropped for topi-cal anesthesia. After placing the sterile eyelid retractor, 5% povidone-iodine was added to the eye surface and left for 3 min and then washed with a sterile isotonic solution. Four mm from the limbus in phakic eyes and 3.5 mm from the limbus in pseudophakic eyes were marked with compasses. Superotemporal quadrant was tried to be preferred as the entry point. 0.1 mL (0.5 mg) RAN was injected from the point determined by the compass with the 30 gauge needle toward the center of the vitreous cavity. The same procedure was followed in the DEX group, but additionally, subconjunctival anesthesia was applied and the DEX implant was injected into the vitreous with a 22 gauge applicator.
A short-term gentle pressure was applied to the injection site with a cotton-tipped applicator immediately after the injection to prevent the drug or vitreous from leaking back and bleeding from the conjunctiva. The tone of the eye was controlled digitally. Whether there was a sense of light was questioned. Antibiotic drops were given to all patients for one week and they were warned to apply to the emergency department if they have complaints such as sudden vision decrease, pain, and redness. Patients were called for control the next day and examined for infection and sudden IOP increase.
