  • Pain

Purpose:

The purpose of this study is to determine if a smaller needle size reduces discomfort suffered by patients both during and following intravitreal injections. It is the investigators belief that using a smaller size needle will help patients to be less fearful of intravitreal injections and more amenable to treatment. This study will also evaluate the effect of needle size on post injection intraocular pressure, to see if smaller needles may reduce wound leak and increase the intraocular pressure following injection. The investigators hypothesize that subject eyes injected with the smaller size needle will result in greater patient comfort both during and after their injection as compared to the eye injected with the larger needle. The investigators objective is to reduce any discomfort felt by patients who receive intravitreal injections. The investigators also hypothesize that the smaller needle will result in higher post injection pressures, and another objective is to determine if this can affect patient comfort and increase the risk of glaucomatous optic nerve damage.


Criteria:

Inclusion Criteria: - Ability to provide written informed consent and comply with study assessments for the full duration of the study - Age > 18 years - Subject's normal therapeutic regimen calls for them to receive two sessions of bilateral injections of the same volume of ranibizumab within the next year. - Disease related considerations: None. - Other considerations: Subjects who must be able to report pain scores during and up to 48 hours following an intravitreal injection. Also, subjects must consent to at least 5 intraocular pressure checks per eye for each injection procedure. Exclusion Criteria: - Pregnancy (positive pregnancy test) or lactation - Premenopausal women not using adequate contraception. The following are considered effective means of contraception: surgical sterilization or use of oral contraceptives, barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel, an intrauterine device, or contraceptive hormone implant or patch. - Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated - special classes of subjects (vulnerable subjects), such as fetuses, pregnant women, children, institutionalized mentally disabled, or others, especially those whose ability to give voluntary informed consent may be in question.
