ABSTRACT.Purpose: To evaluate the influence of the needle size used for intravitreal (IVT) injections on patients' pain experience in a randomized, double-armed, singleblinded, clinical trial. Methods: Patients included were randomized to have an IVT injection performed with a 27-gauge needle (group 1) or with a 30-gauge needle (group 2). The topical anaesthesia before the injection was standardized. Immediately after the injection, patients were asked to grade their pain using the visual analogue scale (VAS) and the Wong-Baker FACES scale. The main outcome measure was the pain score assessment. Cofactors analysed were patients' demographics (age and gender) and clinical characteristics (such as the number of previous IVT injections). In addition, scaled surgeon's questionnaires to assess the IVT injection procedure were evaluated. For statistical analysis, a regression model was used. Results: The data of 208 patients (group 1: 104 patients; group 2: 104 patients) were analysed. There was no significant difference in the VAS pain scores (p > 0.18) and in the Wong-Baker pain scores (p > 0.59) between both treatment groups. Gender (p = 0.0288) and the number of previous IVT injections (p = 0.0028) significantly influenced the VAS pain scores (p < 0.05). Female patients and patients with a history of previous IVT injections had higher pain scores. The surgeon's questionnaire showed an overall preference towards the use of a 30-gauge needle for IVT injections. Conclusion: The use of a 30-gauge needle for IVT injections showed no significant effect in pain relief compared to the use of a 27-gauge needle. However, a 30-gauge needle was preferred by all surgeons.

“…There is general agreement between IVI guidelines that injections should be made through the pars plana, between 3.5 and 4 mm from the limbus [2, 132]. A more posterior injection site potentially increases the risk of retinal detachment, while a more anterior approach increases the risk of traumatic cataract formation or hemorrhage, if the ciliary body is pierced.…”

“…Regarding EO risk after IVI, needle size does not seem to be a relevant factor [131]. Thirty-gauge or thinner needles are recommended for liquid injections [132], whereas larger needles should be used when necessary, as for example for Ozurdex® injections. Expert panel guidelines suggest using any needle length from 13 to 18 mm [2, 115].…”

“…Most guidelines or expert opinions leave the selection of the quadrant to the injecting physician, based on patient-specific considerations [49]. If patients receive repeated IVI, it is also recommended to avoid injection in presclerotomy areas and switch injection sites, in order to prevent cumulative vitreous incarceration and persisting scleral hole [132]. …”

2018 Update on Intravitreal Injections: Euretina Expert Consensus Recommendations

Intravitreal injections (IVI) have become the most common intraocular procedure worldwide with increasing numbers every year. The article presents the most up-to-date review on IVI epidemiology and techniques. Unfortunately, important issues related to pre-, peri- and postinjection management lack randomized clinical trials for a final conclusion. Also, a great diversity of approaches exists worldwide. Therefore, expert consensus recommendations on IVI techniques are provided.

Интравитреальные инъекции в условиях реальной клинической практики: результаты опроса врачей-офтальмохирургов Уральского федерального округа // Офтальмологические ведомости." Интравитреальные инъекции (ИВИ) широко распространены в современной офтальмологической практике в качестве способа доставки лекарственных препаратов при различных патологиях заднего отрезка глаза. Несмотря на накопленный опыт, некоторые аспекты выполнения процедуры остаются дискутабельными. Кроме того, в литературе нет данных о практических аспектах проведения ИВИ в России в реальных клинических условиях. В данной работе проанализированы результаты анонимного опроса 74 офтальмологов Уральского федерального округа, осуществлённого в 2018 г. с помощью оригинальной анкеты, включавшей 20 вопросов. Установлено, что респонденты в целом разделяют традиционный для России подход к ИВИ как к полостной офтальмологической операции. В ходе опроса выявлено отсутствие единых подходов и неполное следование современным руководящим принципам в отдельных аспектах выполнения процедуры, в связи с чем предложены корректирующие мероприятия."
