The purpose of this study was to investigate the changes in subfoveal choroidal thickness (SFCT) after intravitreal injection of bevacizumab (IVB) for neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME). This retrospective, consecutive, interventional case series study included 43 eyes [21 affected eyes with neovascular AMD (AMD group) and 22 affected eyes with DME (DME group)] which were treated with 1.25 mg/0.5 ml IVB and 43 untreated fellow eyes of 43 patients. SFCT was measured in all 86 eyes at baseline before IVB injection and at day 1, week 1, and month 1 after injection by use of enhanced depth imaging optical coherence tomography (EDI OCT). Central foveal thickness (CFT) and best-corrected visual acuity were analyzed at baseline and during follow-up visits. Main outcome measure was change in SFCT in 1 month after treatment. All 43 eyes treated with IVB showed a significant reduction in SFCT. Mean SFCT in treated eyes decreased from 237.1 ± 75.3 µm at baseline to 214.0 ± 65.7 µm at day 1, 205.4 ± 59.7 at week 1, and 222.7 ± 73.3 at month 1, whereas SFCT in fellow eyes changed from 228.4 ± 63.6 at baseline to 224.5 ± 68.5 at day 1, 220.4 ± 72.1 at week 1, and 226.9 ± 74.0 at month 1. SFCT demonstrated a similar trend toward decrease in both groups. CFT decreased significantly and visual acuity improved significantly. SFCT decreased significantly in AMD and DME eyes following injection. The decreasing effect of bevacizumab on choroidal thickness was highest at first week and continued to the end of first month after injection. [ABSTRACT FROM AUTHOR]

To evaluate the approach to management of iatrogenic crystalline lens injury occurred during intravitreal injection (IVI). The patients who were managed operatively or followed-up without intervention after the iatrogenic lens injury due to IVI were included in the study. Capsular breaks remained either quiescent or resulted in cataract formation in the patients with inadvertent crystalline lens capsule damage. Phacoemulsification surgery was performed in patients with cataract formation with lower fluidic settings. A total of 9 cases included in the study. Seven cases underwent phacoemulsification with intraocular lens implantation. Two cases remained as quiescent lens injury during the follow-up. In 2 cases, dislocation of lens fragments occurred during phacoemulsification where pars plana vitrectomy was performed at the same session. After iatrogenic crystalline lens injury, capsular damage could remain quiescent or progress to cataract formation. Although phacoemulsification surgery can be performed with appropriate parameters, lens fragment dislocation can be observed in cases with traumatic lens damage secondary to IVI.
