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 in 58 eyes, and at Stage 4 in 38 eyes. The rate of increase of the hole diameter was 26.0 ± 42.3% at Stage 2, 5.52 ± 15.5% at Stage 3, and 8.04 ± 18.7% at Stage 4. The rate of change at Stage 2 was significantly greater than that at Stage 3 and Stage 4 (both P

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 and UT2, were measured at preoperative, intraoperative, and postoperative time points.

Results:

In the Phaco-PPV group using the SOM, intraoperative muscle tone and stiffness were higher than preoperative and postoperative values in the sternocleidomastoid (P 0.05).

Conclusion:

This study provides quantitative measurement of retina surgeon ergonomics, suggesting that compared with a SOM, the DAVS can reduce intraoperative muscle fatigue.

Purpose:

Age-related scattered hypofluorescent spots on late-phase indocyanine green angiography (ASHS-LIA) might represent hydrophobic neutral lipid deposits in the Bruch membrane. This study aimed to report retentional avascular pigment epithelia…

Purpose:

To explore the effectiveness, safety and psychological impact of foldable capsular vitreous body (FCVB) implantation for complicated retinal detachment caused by severe ocular trauma.

Methods:

This was a prospective, single-arm, surgical interventional case series study. A standard 3-port 23-gauge pars plana vitrectomy was performed, and the FCVB was implanted into the vitreous cavity. Observed indicators, including the best-corrected visual acuity, intraocular pressure (IOP), retinal reattachment, complications, and patient satisfaction, were analyzed to evaluate the study.

Results:

A total of 28 cases (eyes) were enrolled, with a mean follow-up of 16.93 ± 9.67 months and an average age of 51.11 ± 10.14 years, including 22 men (78.57%). The FCVB was successfully implanted, and the retina was reattached in all cases. The postoperative best-corrected visual acuity improved in 7 cases, and remained unchanged in 21 cases (P > 0.05). The average IOP was 7.01 ± 2.43 mmHg before surgery and 8.54 ± 2.93 mmHg after surgery (P
