Objective: To determine the effect of intravitreal injection into differentquadrants on pain score and injection comfort. Method: 304patients were divided into 8 groups that included 38 patients in each. Theright and left eyes of the patients were divided into 4 quadrants, superiortemporal, inferior temporal, superior nasal, and inferior nasal. Intravitrealinjections were performed in the room only used for this purpose and by anexperienced ophthalmologist. To eliminate drug-related factors onlyintravitreal ranibizumab applied patients were included in the study. Injectionswere performed on one of these quadrants 3.5 mm away from the limbus using 30gauge needle. All injections were performed under topical proparacaine HClanesthesia. The severity of the patient's pain after the injection was evaluatedby using the visual analog scale. Additionally the patient's stinging,injection comfort and injection safety were also assessed.Results: 176(57.9%) of the participants were male and 128 (42.1%) were female. The mean ageof all participants was 61,84±12,49 (20-90). Age (p=0,793), gender (p=0,534),pain score (p=0,165), stinging score (p=0,264), patient comfort score (p=0,555),injection safety score (p=0,079) were similar between the groups. Pain(p<0,001) and stinging (p<0,001) scores were higher in females(p<0,001). Patient comfort (p=0,001) and injection safety (p=0,019) scoreswere lower in females. Conclusions: No difference was foundbetween the quadrants in terms of pain score. Therefore, the physicians may prefer the most comfortable quadrant for themselvesand for their patients in intravitreal injection.
