Comparison of surgeon muscular properties between standard operating microscope and digitally assisted vitreoretinal surgery systems
Purpose:
To quantitatively analyze surgical ergonomics between standard operating microscope (SOM) and digitally assisted vitreoretinal surgery (DAVS) systems.
Methods:
The surgeon conducted procedures on 110 patients; 52 patients underwent a combined phacoemulsification and pars plana vitrectomy (Phaco-PPV group, 24 using SOM and 28 using DAVS), and 58 patients underwent phacoemulsification (Phaco group, 30 using SOM and 28 using DAVS). The surgeon's muscle tone and stiffness in the sternocleidomastoid and the two positions of the upper trapezius (UT), which are 2-cm intervals along the UT muscle fibers, UT1 an...

Idiopathic multifocal choroiditis with serpiginous-like peripapillary chorioretinal atrophy
Conclusion:
Multifocal choroiditis may present with peripapillary chorioretinal changes resembling a serpiginous-like choroiditis in addition to the classic findings of patches of atrophy or punched-out scars in the posterior pole or periphery, cone-shaped retinal pigment epithelium elevated on optical coherence tomography and peripheral curvilinear streak lesions.

VALUABLE APPLICATION OF THE β-d-GLUCAN TESTING OF INTRAOCULAR FLUID FOR THE DIAGNOSIS OF FUNGAL ENDOPHTHALMITIS
Purpose:
To evaluate the value of the β-d-glucan (BDG) testing of intraocular fluid for the diagnosis of fungal endophthalmitis (FE).
Methods:
Twenty patients (22 eyes) with FE were diagnosed using both culture and nonculture methods. Intraocular fluid was collected for BDG testing, including 22 eyes of FE and 55 eyes of control group. Under different BDG cutoff points as the test-positives, the BDG sensitivity, specificity, positive predictive value, and negative predictive value for FE were analyzed.
Results:
The BDG testing value was 1,022.78 ± 1,362.40 pg/mL in the FE group, significantly higher tha...

IMPACT OF COVID-19 PANDEMIC LOCKDOWNS ON VISUAL ACUITY OF PATIENTS WITH NEOVASCULAR AMD: A Large Cohort
Purpose:
Evaluating the impact of delayed care, secondary to coronavirus disease 2019 (COVID-19) pandemic lockdowns, on visual acuity in previously treated neovascular age-related macular degeneration (nAMD) patients.
Methods:
This was a multicenter, retrospective, study of patients with nAMD previously treated with anti-VEGF injections who were followed up during 2019 (pre–COVID-19) and compared with patients with nAMD during 2020 (COVID-19).
Results:
A total of 1,192 patients with nAMD with a mean age of 81.5 years met the inclusion criteria. Of these, 850 patients were assessed in 2019 (pre–COVID-1...

A MULTICENTER REVIEW EVALUATING THE RISK OF RHEGMATOGENOUS RETINAL DETACHMENT POST ENDOPHTHALMITIS: A Canadian Retina Research Network Investigation
Conclusion:
All patients with RD post endophthalmitis required additional surgery, and functional outcomes remained poor. Nevertheless, repair of these RDs can preserve some vision and be globe saving. (Source: RETINA)

Evaluation of retinal displacement following primary scleral buckling for macula-involving rhegmatogenous retinal detachment
Conclusion:
Retinal displacement does not seem to be a frequent complication of primary scleral buckling surgery for macula-involving rhegmatogenous retinal detachment. (Source: RETINA)

Ocular factors related to preoperative enlargement of idiopathic macular hole diameter
Purpose:
To determine the preoperative factors that are significantly correlated with an enlargement of an idiopathic macular hole (MH) during the one-month preoperative period.
Methods:
This was a retrospective cross-sectional study of patients with MH who had undergone vitrectomy in the Kagoshima University Hospital. The stage of the MH was determined by using spectral domain optical coherence tomography. Patients who had optical coherence tomography images at two time points more than 14 days apart before the vitrectomy were studied.
Results:
The MH participants were at Stage 2 in 44 eyes, at Stage 3 i...

Effects of ectopic inner foveal layers on foveal configuration and visual function after idiopathic epiretinal membrane surgery
Purpose:
To investigate the effects of ectopic inner foveal layers (EIFLs) on foveal configuration recovery and visual acuity after idiopathic epiretinal membrane removal and analyze the relationship of foveal configuration recovery between 1-month and long-term postoperatively.

A comprehensive ophthalmic examination was performed for all patients before and 1, 4, 10, and 24 months after surgery. We observed the postoperative anatomical and functional recovery of eyes with and wi...

Associated factors and surgical outcomes of microcystoid macular edema and cone bouquet abnormalities in eyes with epiretinal membrane
Conclusion:
Although CBA had no prognostic consequences, MME was associated with suboptimal visual recovery and less efficient control of inflammation after surgery. Degeneration of Müller cells may have an alleged role, and further imaging and functional tests are warranted. (Source: RETINA)
