2.Full-thickness Macular Hole after Intravitreal Aflibercept Injection in a Patient with Wet Age-related Macular Degeneration.
Journal of the Korean Ophthalmological Society 2017;58(7):875-878
PURPOSE: To report a case of full-thickness macular hole following intravitreal aflibercept injection in a patient with wet age-related macular degeneration (AMD). CASE SUMMARY: A 70-year-old man presented to our department with gradually decreasing vision in his left eye. Best-corrected visual acuity was measured as 0.8 in the right eye and 0.2 in the left eye. Fundus examination, fluorescein angiography, and optical coherence tomography (OCT) showed occult choroidal neovascularization associated with subretinal fluid in the left eye. The patient received several intravitreal ranibizumab and bevacizumab injections in his left eye but responded poorly to the treatment. The patient was switched to intravitreal aflibercept injection. After 1 month, the best corrected visual acuity in the left eye was decreased to 0.05. Although the fundus examination was indistinct, OCT confirmed the presence of a full-thickness macular hole. The patient underwent pars plana vitrectomy with internal limiting membrane peeling and fluid-gas exchange, 20% SF6 gas injection, phacoemulsification, and posterior chamber intraocular lens implantation. One month after the operation, the best corrected visual acuity was 0.2. The macular hole was closed completely, as confirmed by OCT. CONCLUSIONS: Although the occurrence of a full-thickness macular hole after intravitreal aflibercept injection in the treatment of choroidal neovascularization with wet AMD is uncommon, physicians should pay attention for this complication.

Journal of the Korean Ophthalmological Society 2020;61(7):778-783
Purpose:
This study aimed to compare the surgical outcomes of 23-gauge (g) micro-incision vitrectomy surgery (MIVS) and 25-g MIVS for lens fragments that dropped into the vitreous cavity during cataract surgery.
Methods:
This study was a comparative, retrospective, and interventional case series study based on a medical records review. Sixty-six eyes of 66 patients with dropped lens fragments in the vitreous cavity during MIVS, performed between January 1, 2014 and December 31, 2017, were included. The characteristics of the patients and their visual acuity, operation time duration, and complication rate were analyzed retrospectively.
Results:
23-MIVS and 25-g MIVS were performed on 41 and 25 eyes, respectively. The mean value of best-corrected visual acuity (logMAR) improved significantly from 1.79 ± 1.12 to 0.36 ± 0.63 in the 23-g group and from 1.82 ± 1.15 to 0.31 ± 0.53 in the 25-g group (p < 0.001). The mean operation time was 33.0 ± 6.8 minutes in the 23-g group and 32.3 ± 6.9 minutes in the 25-g group, with no significant difference between the two groups (p = 0.694). There were two cases of postoperative cystoid macular edema in the 23-g group; however, no significant difference with regard to postoperative complications was found between the two groups (p = 0.262).
Conclusions
23- and 25-g MIVS for lens fragments dropped into the vitreous cavity during cataract surgery is a comparably safe and effective method for reducing the size of the incision and shortening the operation time.
5.Surgical Outcomes of Intravitreal Torsional Phacoemulsification for Dropped Lens Fragments during Cataract Surgery
Journal of the Korean Ophthalmological Society 2020;61(5):500-505
Purpose:
To evaluate the surgical outcomes of microincision pars plana vitrectomy (PPV) and intravitreal torsional phacoemulsification in eyes with dropped nuclear fragments following complicated cataract surgery.
Methods:
A retrospective analysis of 22 eyes of 22 patients who underwent microincison PPV for lens fragments dropped into the vitreous cavity during cataract surgery between January 2014 and December 2017 with a minimum 6-month follow-up was performed. Pre- and postoperative visual acuity, and intra- and postoperative complications (retinal detachment, retinal tear, cystoid macular edema, and thermal burns of the sclerotomy site) were recorded.
Results:
The study included 17 males and 5 females. The mean age of patients was 71.3 ± 8.2 years. The mean interval between cataract surgery and PPV was 0.4 ± 0.8 days, and all PPV procedures were performed within 3 days after cataract surgery. The mean best-corrected visual acuity (LogMAR) was 1.37 ± 0.79 in the preoperative state, which improved significantly to 0.21 ± 0.15 in the postoperative state (p < 0.001). No complication such as thermal burns of the sclerotomy site and retinal damage due to lens fragments occurred during intravitreal torsional phacoemulsification. Postoperative cystoid macular edema occurred in two eyes, which was managed medically. No retinal detachment was noted.
Conclusions
Microincision PPV and intravitreal phacoemulsification using a torsional phacoemulsification probe for lens fragments dropped into the vitreous cavity during cataract surgery was a safe and effective method, which resulted in visual improvement without any complication directly attributable to the probe.

Purpose:
To evaluate the clinical outcomes of 25-gauge microincision vitrectomy for vitreoretinal diseases in patients who have undergone glaucoma drainage implant surgery for the treatment of neovascular glaucoma.
Methods:
We retrospectively examined the preoperative and postoperative best corrected visual acuity (BCVA), intraocular pressure (IOP), and complications of patients with previous Ahmed valve implantation surgery who underwent vitrectomy and were available for follow-up for at least 6 months.
Results:
A total of 20 eyes had Ahmed valve implantation for neovascular glaucoma, of which 16 eyes (80%) had proliferative diabetic retinopathy, and 4 eyes (20%) had central retinal vein occlusion. All eyes underwent 25-gauge microincision vitrectomy for the treatment of vitreous hemorrhage unresponsive to conservative treatment. BCVA (logarithm of minimal angle of resolution, logMAR) improved from 1.08 ± 0.29 preoperatively to 0.61 ± 0.32 (p = 0.004) postoperatively. Mean IOP increased from 16.2 ± 3.4 mmHg preoperatively to 17.4 ± 2.8 mmHg at 6 months postoperatively (p = 0.569), with no significant change. There were no cases of exposed body or tube of Ahmed valve after surgery, and vitreous hemorrhage (7 eyes, 31.8%) was the most common complication.
Conclusions
With a carefully chosen incision site, 25-gauge microincision vitrectomy is an effective treatment method to treat vision-threatening complications such as vitreous hemorrhage in eyes previously implanted with a glaucoma drainage device, with minimal impact on elevated intraocular pressure.

Journal of Nutrition and Health 2021;54(1):67-75
Purpose:
The theory of planned behavior (TPB) was used to investigate how the psychological constructs of attitude, subjective norms, and perceived behavioral control (PBC) affect the individual intention of behaviors in adults. Social support is also important in enabling the stability of healthy eating. This study examined the relationship between three major constructs of TPB as well as social support and the intention of healthy dietary behaviors in adults residing in Beijing, China using the extended TPB.
Methods:
The study questionnaire was based on previously validated items and an online survey was conducted from October to November 2020. Using a total of 244 Chinese adults in Beijing, multiple linear regression analysis was used to test the relationships between three major constructs of TPB as well as the social support and intention of healthy eating.
Results:
Among the three major constructs of TPB, subjective norms (p = 0.044) and PBC (p = 0.000) were significantly related to the behavioral intention of healthy eating (p = 0.000), and the model explained 76.6% of the variance of the behavioral intention from the three constructs of TPB included in the multiple linear regression model. The additional inclusion of social support to the model did not increase the explanatory power of the model to describe the behavioral intention of healthy eating. The subjective norms (p = 0.040) and PBC (p = 0.000) were still significant where social support did not explain the variance of the behavioral intention adequately.
Conclusion
The subjective norms and PBC may be potential determinants of the behavioral intention of healthy eating in adults residing in Beijing, China. These study results can be used to promote healthy eating in Chinese adults living in urban areas. Large-scale intervention studies will be needed to determine if social norms and PBC predict the actual behaviors of healthy eating in Chinese adults
