Purpose:

To quantify the rate of idiopathic macular hole progression from presentation and identify factors that may influence stratification and urgency for surgical listing based on the initial optical coherence tomography scans.

Methods:

The minimal linear diameter (MLD), base diameter (BD), and hole height on nasal and temporal sides of idiopathic macular hole were measured on spectral domain optical coherence tomographies, on initial presentation and just before surgery. Mean hole height, hole height asymmetry (absolute difference between nasal and temporal height), MLD/BD, and MLD change per day (MLD/day) were calculated for each patient. Multivariable linear regression analysis with MLD/day as the dependent variable was performed to identify significant risk factors for MLD progression. Minimal linear diameter was grouped to quintiles: 1: ≤290 µm, 2: >290 µm and ≤385 µm, 3: >385 µm and ≤490 µm, 4: >490 µm and ≤623 µm, and 5: >623 µm.

Results:

In 161 eyes (157 patients), we report significant associations with MLD/day: 1) MLD/BD (P = 0.039) (i.e., wide BD relative to MLD lead to faster progression of MLD), 2) hole height asymmetry (P = 0.006) (larger absolute difference between nasal and temporal hole height lead to faster progression), and 3) days between scans (P

Purpose:

To determine the longitudinal changes in patterns of inner scleral curvature and development of posterior staphylomas in the eyes of highly myopic youths.

A retrospective, longitudinal study. Ultra-widefield optic coherence…

Purpose:

To evaluate the efficacy of anterior segment optical coherent tomography (AS OCT) in estimating the length of the pars plana and optimizing the sclerotomy entry site in vitrectomy for highly myopic eyes, facilitating membrane peeling.

Purpose:

To calculate the retinal surface alternatively in contact with gas and aqueous because of fluid sloshing during daily activities such as ocular saccade, turning the head, standing up, and being a passenger of a braking car.

Methods:

Fluid dynamics of aqueous and gas tamponade was reproduced using computational methods using the OpenFOAM open-source library. The double-fluid dynamics was simulated by the volume of fluid method and setting the contact angle at the aqueous–gas–retina interface.

Results:

Sloshing increased the retinal surface in contact with aqueous by 13% to 16% regardless of fill rate and standing up determined the largest area of wet retina, followed by car braking, head rotation, and ocular saccade (P

Purpose:

To investigate the long-term changes in visual function and outer retinal abnormalities on en face optical coherence tomography after fovea-off rhegmatogenous retinal detachment and to assess associations between functional outcomes and outer retinal abnormalities.

Methods:

Prospective, observational study. The following data were collected at 1, 3, 6, 12, and 24 months after retinal reattachment: Best-corrected visual acuity, metamorphopsia (M-CHARTS), aniseikonia (New Aniseikonia Test), altered ellipsoid zone reflectivity, outer retinal folds, macular detachment demarcation, and subfoveal fluid.

Results:

Thirty-eight patients were included. Best-corrected visual acuity improved significantly from 1 to 12 months and from 12 to 24 months (P

Purpose:

To investigate different modes of foveal regeneration after the closure of idiopathic macular hole (IMH) or highly myopic macular hole (HMMH) by vitrectomy with internal limiting membranes peeling or flap techniques.

Methods:

This retrospective observational study followed 47 IMH and 50 HMMH eyes for at least 6 months. Twenty four IMH and 25 HMMH eyes underwent internal limiting membrane peeling, whereas 23 IMH and 25 HMMH eyes received inverted internal limiting membrane flap technique. Spectral domain optical coherence tomography was used to analyze macular hole closure, foveal microstructures, and excessive gliosis as a foveal “peak-like” protuberance.

Results:

A single procedure closed all IMH (n = 47). For HMMH, the inverted group (n = 25, 100%) closed more macular hole than the peeling group (n = 14, 56.00%) (P 29.985 mm) was linked to excessive gliosis growth.

To report the pattern and characteristics of drusen subtypes in Asian populations and the association with choroidal thickness.

Purpose:

To describe the clinical characteristics and posterior vitreous findings of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD).

Methods:

Eighty-six eyes from 80 patients who were diagnosed with SRRRD (SRRRD group) and 92 eyes from 92 patients who had undergone successful scleral buckling for rhegmatogenous retinal detachment ( group for comparison) were included. Ultrawide field fundus imaging and spectral domain optical coherence tomography were performed to evaluate fundus characteristics and vitreoretinal interface.

Results:

A significant difference was found in the proportion of complete posterior vitreous attachment between the SRRRD and rhegmatogenous retinal detachment groups (44.2% vs. 19.6%, P

Purpose:

To assess 5-year cumulative incidence and risk factors of fellow eye involvement in Asian neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy.

Methods:

In a prospective cohort study of Asian nAMD and polypoidal choroidal vasculopathy, the fellow eyes were evaluated for exudation. The 5-year incidence of exudation was compared between nAMD and polypoidal choroidal vasculopathy.

Results:

A total of 488 patients were studied. The 5-year incidence of exudation in fellow eyes was 16.2% (95% confidence interval: 12.0–20.2). Polypoidal choroidal vasculopathy compared with nAMD in the first eye was associated with lower fellow eye progression (9.8% [95% confidence interval: 5.1–14.3]) vs. 22.9% [95% confidence interval: 15.8–29.3], P
