Purpose: To evaluate the risk factors for retinal pigment epithelium (RPE) tears after intravitreal ranibizumab injections in neovascular age-related macular degeneration (nAMD) and to determine the efficacy of continued ranibizumab treatment after RPE tears.
Methods: A total of 407 treatment-naïve eyes (377 patients) with nAMD were retrospectively included. All patients were treated with an initial series of 3 monthly loading injections, followed by further injections as required. Baseline characteristics and pigment epithelial detachment (PED) lesion features were evaluated as potential risk factors for RPE tear. The visual and anatomical outcomes after treatment during 12 months were also evaluated.
Results: By 12 months, RPE tears developed in 32 eyes (7.9%). Pigment epithelial detachment height was associated with a higher risk of RPE tear (odds ratio [OR], 1.318; 95% confidence interval [CI], 1.217-2.031, P = 0.018). Fibrovascular PED compared with serous PED had a higher risk of developing tears (OR, 9.129; 95% CI, 6.228-32.124, P = 0.039), and typical nAMD (OR, 4.166; 95% CI, 2.030-14.913, P = 0.031) and retinal angiomatous proliferation (OR, 3.778; 95% CI, 2.185-9.277, P = 0.040) had a higher risk of developing tears compared with polypoidal choroidal vasculopathy. Mean best-corrected visual acuity (BCVA) of RPE tear patients showed no significant improvement after treatment at 12 months; however, patients with RPE tears without foveal involvement (19 eyes) showed significant BCVA improvement at 12 months (P = 0.034).
Conclusion: PED type and nAMD subtype are associated with the development of RPE tears after intravitreal ranibizumab injections. Continued ranibizumab therapy after RPE tear development can maintain visual acuity when the fovea is not involved.

Background: Uveitis is an inflammatory ocular disease secondary to disruption of the retinal pigmented epithelium (RPE) and blood retinal barrier (BRB). Known clinical factors do not accurately predict uveitis risk in Juvenile Idiopathic Arthritis (JIA). Tear fluid is easily obtained for biomarker study.

We report the familial occurrence of a severe phenotype of central serous chorioretinopathy (CSC). A 62-year-old man was referred to our institute to treat a macular lesion in his right eye. Best-corrected visual acuity (BCVA) in his right eye was 0.

Purpose: This study aimed to evaluate the factors associated with retinal pigment epithelium (RPE) tear development in the early phase after anti-vascular endothelial growth factor (VEGF) drug initiation in eyes with neovascular age-related macular degeneration (nAMD) and retinal pigment epithelial detachment (PED).
Methods: Treatment-naive eyes with nAMD and PED for which anti-VEGF drug injections had been initiated and followed up for at least 3 months after the 1st anti-VEGF drug injection, were retrospectively investigated. Baseline characteristics of the PEDs, including type, height, and area, were evaluated using fundus photographs, fluorescein angiography, and optical coherence tomography images.
