Purpose: We present a case of Uveitis-Glaucoma-Hyphema (UGH) syndrome secondary to intraocular lens (IOL) subluxation and associated Soemmering ring.Case summary: A 56-year-old female presented with recurrent episodes of right eye uveitis, vitritis, and vitreous hemorrhage, along with progressive vision loss that had not responded to treatment at a private clinic. On examination, her best-corrected visual acuity (BCVA) was 0.4, and intraocular pressure (IOP) was elevated at 34 mmHg. Slit-lamp and fundoscopic evaluation revealed a subluxated IOL and an adjacent Soemmering ring in contact with the iris, accompanied by anterior chamber inflammatory cells, hyphema, and vitreous hemorrhage. A diagnosis of UGH syndrome secondary to IOL subluxation was made. The patient underwent pars plana vitrectomy with the removal of the subluxated IOL and Soemmering ring, followed by scleral fixation of a new IOL using the Yamane technique. Postoperative recovery was favorable, with resolution of anterior chamber inflammation. At follow-up, BCVA had improved to 1.0, and IOP had normalized to 14 mmHg without the need for antiglaucoma medications. Conclusions UGH syndrome resulting from IOL subluxation and a Soemmering ring can be managed effectively via timely surgical intervention, restoring visual acuity and normalizing IOP.

Purpose: To report a case of sequential hydrophilic acrylic intraocular lens (IOL) opacification in both eyes following Ahmed valve implantation in a patient with neovascular glaucoma secondary to diabetes.Case summary: A 59-year-old man was referred to our clinic with ocular pain and elevated intraocular pressure (IOP) three months after undergoing bilateral cataract surgery with hydrophilic acrylic IOL implantation. Examination revealed bilateral proliferative diabetic retinopathy and neovascularization of the iris and anterior chamber angle. The IOP measured 24 mmHg in the right eye and 57 mmHg in the left eye. The patient was diagnosed with neovascular glaucoma secondary to diabetes. Due to uncontrolled IOP, Ahmed valve implantation was initially performed in the left eye. Two years later, the patient experienced decreased visual acuity in the left eye, and a round central opacification of the IOL optic was noted. The opacified IOL was explanted, and a new IOL was implanted with scleral fixation. During follow-up, Ahmed valve implantation was also required in the right eye due to progression of neovascular glaucoma. Two years postoperatively, similar pattern of IOL opacification was observed in the right eye, necessitating the same surgical management. Conclusions Hydrophilic acrylic IOL opacification may occur following Ahmed valve implantation, and is potentially related to altered aqueous humor dynamics, pH changes, and chronic inflammatory responses.

Purpose: We evaluated the treatment outcomes of intravitreal 0.625% povidone-iodine (PI) injection in patients with exogenous and endogenous endophthalmitis. Methods: We retrospectively analyzed the medical records of 21 patients (23 eyes) who received intravitreal 0.625% PI injections for endophthalmitis between March 2021 and December 2023. Results: Of the 21 patients, 19 (19 eyes) had exogenous endophthalmitis, with the most common etiology being post-cataract surgery endophthalmitis in 14 eyes (58.3%). The mean number of intravitreal PI injections administered was 1.6 ± 0.7. The mean time to hypopyon resolution was 2.5 ± 2.1 days. Pars plana vitrectomy (PPV) was required in 16 eyes (84.2%), with an average of 1.1 ± 0.5 surgical interventions. The best-corrected visual acuity (BCVA, logMAR) improved significantly from 2.06 ± 0.52 before treatment to 1.00 ± 0.96 after treatment (p < 0.001). Four eyes of two patients with endogenous endophthalmitis received a mean of 2.5 ± 1.0 intravitreal PI injections (range: 2-4). Clinical improvement was observed in all cases. Conclusions Intravitreal 0.625% PI injection appears to be a potentially effective alternative to conventional antibiotic therapy for the treatment of endophthalmitis.

Purpose: Postoperative endophthalmitis is a sight-threatening intraocular infection requiring prompt treatment. This study aimed to compare the clinical outcomes of intravitreal 0.625% povidone-iodine (PI) injection with intravitreal antibiotic injection for the treatment of postoperative endophthalmitis. Methods: A retrospective review of 40 eyes diagnosed with postoperative endophthalmitis was conducted. Patients were divided into two groups: group 1 received intravitreal 0.625% PI injection (0.1 mL), while group 2 received intravitreal antibiotic injection. Clinical data, including best-corrected visual acuity (BCVA), intraocular pressure, the number of intravitreal injections, duration of anterior chamber hypopyon, and the need for pars plana vitrectomy (PPV), were analyzed. Results: Group 1 (24 eyes) showed significant improvements in BCVA posttreatment (mean, 1.04 ± 0.95 logMAR; p < 0.001) compared to group 2 (16 eyes; mean, 1.26 ± 0.99 logMAR; p = 0.092). Severe visual impairment (BCVA < 10 / 100) was significantly less frequent in group 1 (25.0%) than in group 2 (62.5%) (p = 0.025). The mean duration of hypopyon was shorter in group 1 (2.6 ± 2.2 days) compared to group 2 (6.4 ± 7.3 days, p = 0.048). Fewer intravitreal injections (p = 0.002) and PPV (p = 0.002) were required in group 1. Conclusions Intravitreal 0.625% PI injection was associated with fewer intravitreal injections, shorter hypopyon duration, and more favorable visual outcome–related measures, including significant visual improvement from baseline and a lower frequency of severe visual impairment, compared with intravitreal antibiotic treatment. These findings suggest that PI may be considered a safe and effective initial treatment option for postoperative endophthalmitis. Further prospective studies are needed to validate these results.

Purpose: Food freshness may influence the healthy eating choices of consumers. This study aimed to examine whether self-reported market food freshness moderates the relationships between the three major constructs of the theory of planned behavior (TPB) and the intention for healthy eating among Chinese adults. Methods: A cross-sectional online survey was conducted in 2019 among 408 Chinese adults aged 18–64 years residing in Shanghai and parts of the Anhui Province, using a previously validated questionnaire. Structural equation modeling was applied to examine the moderating effects of market food freshness. Results: Based on a single subjective measure, 42.9% of the participants perceived market food freshness as low, and 57.1% perceived it as high. In the unconstrained model, perceived behavioral control (PBC) showed positive relationships with both short-term and long-term intentions for healthy eating (p < 0.001). Among participants reporting lower market food freshness, the relationship between PBC and short-term intention remained significant (p < 0.001), and the relationship between short-term and long-term intentions became significant (p = 0.042). However, among participants reporting higher market food freshness, PBC maintained significant relationships with short-term (p < 0.001) and longterm (p = 0.028) intentions, and the relationship between subjective norms and short-term intention became significant (p = 0.013). The moderating effect of market food freshness was significant (p < 0.001). Conclusion Market food freshness may moderate the relationships between the TPB constructs and the intentions for healthy eating in Chinese adults. These findings highlight the importance of developing tailored, region-specific strategies to enhance healthy eating behaviors among the Chinese population, accounting for disparities in resource availability and contextual differences. Further research should examine the underlying mechanisms driving regional variations in these associations.

Purpose: To evaluate the refractive outcomes of FineVision multifocal intraocular lens (IOL) implantation after vitrectomy for retinal detachment in eyes that had undergone myopia-correcting refractive surgery. Methods: This study involved 27 eyes from 27 patients who received FineVision multifocal IOL implantation due to nuclear cataract following vitrectomy for retinal detachment. All patients had previously undergone myopia-correcting refractive surgery. Preoperative and postoperative visual acuity and manifest refraction were measured. Prediction errors were compared between 8 eyes with axial length (AL) ≥ 26 mm and 19 eyes with AL < 26 mm, as well as between 9 eyes with macula-involved retinal detachment and 18 eyes without macula involvement. Results: Six months postoperatively, the mean uncorrected distance visual acuity was 0.12 ± 0.14 logarithm of the minimal angle of resolution (logMAR), and near visual acuity was 0.08 ± 0.14 logMAR. The postoperative spherical equivalent (SE) was within ± 0.50 diopters (D) in 9 eyes (33.3%) and within ± 1.00 D in 19 eyes (70.4%). All eyes had SE within ± 1.50 D. Prediction errors did not significantly differ between eyes with AL ≥ 26 mm and those with AL < 26 mm, nor between macula-involved and non-involved groups up to 6 months postoperatively. Conclusions FineVision multifocal IOL implantation resulted in SEs close to the preoperative expected refraction in eyes with previous vitrectomy and myopia-correcting refractive surgery, with all eyes within ± 1.50 D.

Purpose: To report a case of macular serous retinal detachment and macular thinning associated with optic disc pit maculopathy successfully treated with vitrectomy, fovea-sparing internal limiting membrane (ILM) peeling, and inverted ILM flap technique.Case summary: A 27-year-old male patient presented with a 1-month history of decreased right eye vision. Corrected visual acuity in the right eye was 0.025 at initial visit. Fundus examination revealed an oval, deep-seated defect in the inferotemporal portion of the optic nerve and a chorioretinal coloboma located inferior to the optic nerve with a one-third disc diameter. Optical coherence tomography (OCT) showed severe macular serous detachment and central foveal thinning. Surgical treatment comprised vitrectomy, ILM peeling preserving an amount of ILM equivalent to the diameter of one disc in the central fovea and covering the optic disc pit with an inverted ILM flap from its nasal portion. The flap was fixed with a dispersible viscoelastic material and intravitreal 20% sulfur hexafluoride gas injection. The patient was maintained in a facedown position for 3 days postoperatively. After 15 months, the best-corrected visual acuity of the right eye improved to 0.63. Repeat OCT revealed resolution of retinoschisis and serous retinal detachment, with the ILM flap effectively covering the optic disc pit. Conclusions Fovea-sparing ILM peeling with an inverted ILM flap on the nasal side over the optic disc pit in patients with thin inner retinal layers and excessive serous retinal detachment effectively prevent the occurrence of macular holes and treat optic disc pit maculopathy.
