Purpose:
To investigate features of central serous chorioretinopathy with choroidal neovascularization (CNV) on multimodal imaging and analyze their association with treatment response.
Methods:
A total of 37 patients with chronic central serous chorioretinopathy complicated by CNV were divided into bevacizumab and photodynamic therapy groups, and each group was subdivided into responders and nonresponders according to subretinal fluid status at 3 months. We assessed multimodal imaging parameters (subfoveal choroidal thickness; vortex vein engorgement; choroidal vascular hyperpermeability; and CNV morphologic pattern, area, and vessel density) and analyzed their association with treatment responses.
Results:
Responders in the bevacizumab group showed thinner subfoveal choroidal thickness (384.0 ± 103.2 vs. 398.3 ± 87.1 µm, P = 0.042), smaller CNV area (0.512 ± 0.267 vs. 1.323 ± 0.481 mm2, P = 0.007), open-circuit pattern (84.6% vs. 12.5%, P
Purpose:
To assess whether macular fluorescence lifetimes may serve as a predictor for long-term outcomes in macula-off rhegmatogenous retinal detachment.
Methods:
A single-center observational study was conducted. Patients with pseudophakic macula-off rhegmatogenous retinal detachment were included and evaluated 1 and 6 months after successful reattachment surgery. Fluorescence lifetime imaging ophthalmoscopy lifetimes in the central Early Treatment Diabetic Retinopathy Study grid subfield, in two distinct channels (short spectral channel and long spectral channel) were analyzed. Best-corrected visual acuity optical coherence tomography of the macula and fluorescence lifetimes were measured at month 1 and month 6.
Results:
Nineteen patients were analyzed. Lifetimes of the previously detached retinas were prolonged compared with the healthy fellow eyes. Short lifetimes at month 1 were associated with better best-corrected visual acuity improvement (short spectral channel: r2 = 0.27, P
Purpose:

Purpose:
To investigate longitudinal changes in peripapillary choroidal thickness (pCT) and retinal nerve fiber thickness (pRNFLT) in patients with Type 2 diabetes mellitus.
Methods:
This was a prospective observational cohort study. Patients with Type 2 diabetes mellitus without diabetic retinopathy (DR) at baseline were recruited, followed up for three years, and further divided into an incident DR group and a non-DR group according to the outcome. The pCT and pRNFLT were measured through swept-source optical coherence tomography at 1-year interval, and the mean rates of pCT and pRNFLT thinning were compared between the DR groups.
Results:
A total of 682 patients (682 eyes) were included in the final analysis. After 3-years follow-up, 122 (17.89%) developed DR. Both pCT and pRNFLT progressively thinned (−2.37 [−2.80 to −1.95] µm/year; −0.40 [−0.55 to −0.25] µm/year, respectively, P
Purpose:
To evaluate the feasibility and utility of microscope-integrated optical coherence tomography in patients undergoing full-thickness neurosensory retinal autograft for refractory macular hole (MH)-associated retinal detachment.

Purpose:
To investigate the retinal light hazard during macular surgery using a digital three-dimensional visualization system (3D) and a conventional microscope (CM).
Design:
Experimental study and retrospective evaluation of a case–control study.
Subjects:
A total of 20 and 10 patients who underwent pars plana vitrectomy for epiretinal membrane using 3D and CM, respectively.
Methods:
Spectral irradiances of endoilluminators were measured for representative settings used during core vitrectomy and macular manipulations with 3D and CM. From the medical record of the patients, time needed for core vitrectomy and macular manipulations was extracted. The total retinal light hazard index and the macular hazard index were calculated based on the spectral irradiances weighted by the standard functions. Total retinal light hazard index, macular hazard index, and the number of cases that exceeded the maximum permissible radiant power exposure were compared between the two groups.
Results:
The spectral irradiance were 1.6 and 3.9 mW/cm2 for core vitrectomy and 3.4 and 8.1 mW/cm2 for macular manipulations using typical settings for 3D and CM groups, respectively. The total retinal light hazard index ranged from 4.31 kJ/m2 to 17.37 kJ/m2 for 3D and 11.09 kJ/m2 to 27.70 kJ/m2 for CM groups, respectively, whereas the macular hazard index ranged from 2.93 kJ/m2 to 14.58 kJ/m2 for 3D and from 6.84 kJ/m2 to 23.55 kJ/m2 for CM, respectively (P
