RETINA

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

Purpose:

To evaluate the incidence and degree of retinal displacement following scleral buckling surgery for macula-involving rhegmatogenous retinal detachment.

Methods:

Retrospective interventional case series comprised of patients treated …

Background:

In previous landmark studies on central retinal vein occlusion, retinal nonperfusion assessments were obtained using 7-field (7F) angiography. The widespread current use of widefield imaging allows better visualization of the peripheral…

Purpose:

To determine the distribution of macular and cube thickness and their normal range in the students aged 9 years to 15 years and to investigate their associated demographic and biometric factors.

Methods:

This study was based on the data of the second phase of the Shahroud School Children Eye Cohort Study, conducted in 2018. After measurements of visual acuity, biometry, and subjective and cycloplegic refraction, retinal examination was performed using the Zeiss Cirrus HD 4000 optical coherence tomography.

Results:

The data of 5,043 right eyes were analyzed after applying the exclusion criteria. The central macular thickness was 239 ± 19.35 μm. The mean cube volume and cube thickness were 9.94 ± 0.44 and 278 ± 12.20, respectively. According to multiple linear regression analysis, the central macular thickness was significantly lower in girls (coefficient [β]: −9.18; P
