The purpose of this study was to evaluate the feasibility of performing vitrectomies after using bevacizumab (Avastin, Genentech, South San Francisco, CA) for the management of retinal detachments in retinopathy of prematurity. ⋯ These data show that vitrectomy after intravitreal bevacizumab can be effective in selected cases. The regression of the vascular activity induced by this drug might contribute to better results in some of these cases. There were no apparent short-term safety concerns for intravitreal bevacizumab injections in these babies. However, additional studies are needed to define the role of bevacizumab as a possible adjuvant in the management of retinopathy of prematurity retinal detachments.

Randomized Controlled Trial
Oral transmucosal fentanyl citrate: a novel analgesic agent for use in retinal photocoagulation.
To evaluate the analgesic effect of 200 microg oral transmucosal fentanyl citrate during peripheral retinal scatter photocoagulation and to determine the side effect profile. ⋯ OTFC at a dosage of 200 microg is an effective and convenient analgesic for use in peripheral retinal scatter photocoagulation. We found this agent to be well tolerated in the outpatient setting. However, a larger study would be required to ascertain safety across a larger population of opiate-naive patients.

To characterize the in vitro behavior of three preparations of triamcinolone acetonide (TA). ⋯ In vitro, PFTA in Balanced Salt Solution Plus had more aggregates of smaller size than either TA or TAIS. By contrast, TAIS had much larger aggregate size than both PFTA and TA, and this increased over time. These findings correlate with the clinical observations that PFTA and TA tend to disperse throughout the vitreous, whereas TAIS tends to conglomerate and gravitate toward the most dependent portion of the eye in a globular fashion.

To evaluate retinal function in patients on hydroxychloroquine using multifocal electroretinography. ⋯ The mfERG appears to be able to detect decreased retinal function in hydroxychloroquine patients with normal clinical examinations, and may be useful in identifying patients that require close monitoring for the development of clinically relevant toxicity. The Color Difference Plot Scoring System may be used as a tool to aid in the interpretation of results of the mfERG in the clinic setting.
