We investigated whether foveal ellipsoid zone (EZ) status affects visual prognosis in eyes with subretinal fluid (SRF) associated with branch retinal vein occlusion (BRVO). We included 38 eyes retrospectively and classified those with or without a continuous EZ on the SRF of the central foveola on the vertical optical coherence tomography (OCT) image at the initial visit as intact (n = 26) and disruptive EZ (n = 12) groups, respectively. In addition, we classified the intact EZ eyes into clear (n = 15) and blurred (n = 11) EZ groups according to whether EZ on the SRF was observed distinctly or not. Multiple regression analyses showed that baseline EZ status significantly correlated (p = 0.0028) with the 12-months logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), indicating that baseline intact EZ significantly improves visual prognosis. The 12-months logMAR BCVA of the intact EZ group was significantly better (p < 0.001) than that of the disruptive EZ group, and did not differ significantly between the clear and blurred EZ groups. Thus, baseline foveal EZ status on vertical OCT images can be a novel biomarker for visual prognosis in eyes with SRF associated with BRVO.

We aimed to evaluate the safety and efficacy of office-based probing with dacryoendoscopy under local anesthesia for congenital nasolacrimal duct obstruction (CNLDO). This single-institution study retrospectively reviewed data on 72 eyes of 64 consecutive children (38 boys, 43 eyes; 26 girls, 29 eyes), aged between 6 and 17 (mean age: 10.0 ± 2.7) months with suspected CNLDO, from July 2016 to February 2022. These patients underwent probing with dacryoendoscopy under local anesthesia. CNLDO was diagnosed clinically based on the presence of epiphora and sticky eyes due to mucous discharge commencing within the first 3 months of life, increased tear meniscus height, and fluorescein dye disappearance test results. A total of 63 of the 72 eyes had narrowly defined CNLDO, and 9 eyes had other types of obstructions. The intervention success rate was 100% (63/63 eyes) for patients with typical CNLDO and 97.2% (70/72 eyes) for the entire study cohort. Moreover, CNLDO was classified into five types based on the features of the distal end of the nasolacrimal duct. Probing with dacryoendoscopy is safe and yields a high success rate in pediatric patients with CNLDO. This is the first study to assess the safety and efficacy of probing with dacryoendoscopy under local anesthesia in pediatric patients with CNLDO.

We present a rare case of acute retinal pigment epitheliitis (ARPE) following vaccination. An 18-year-old Japanese man visited our hospital with a 5-day history of a central scotoma in the right eye. He had received the second dose of coronavirus disease 2019 vaccination (BNT162b2 mRNA, Pfizer-BioNTech) 1 month prior, following which he developed a low-grade fever of 37.3–37.5°C for 2 days accompanied by joint pain. Although he had received influenza vaccination 5 days prior to this presentation, no systemic symptoms other than injection site pain were observed. Blood test results were unremarkable. Ophthalmological examination revealed a decimal best-corrected visual acuity (BCVA) of 0.8 and 1.2 in the right and left eyes, respectively. Intraocular pressure was 15 mm Hg in both eyes. Intraocular inflammation was not observed. Fundus examination revealed a localized lesion of pigment stippling associated with yellowish hypopigmentation in the fovea. Fluorescein angiography revealed slight transmission hyperfluorescence without leakage. Optical coherence tomography (OCT) revealed disruption of the external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). We diagnosed the patient with ARPE in the right eye. The patient was followed up without treatment. Five weeks after onset, the central scotoma in the right eye disappeared, and patient’s BCVA in the right eye improved to 1.5. OCT showed improvement in ELM and EZ continuity in the right eye, but IZ remained disruptive. Although the exact pathophysiology of the association between ARPE and these vaccinations is unclear, ARPE may develop after the vaccination.

We investigated whether baseline foveal intraretinal fluid (IRF) localization affects the visual prognosis of branch retinal vein occlusion (BRVO). Fifty eyes from 50 patients were included in this retrospective study. We classified the eyes with IRF involving and not involving the central foveola on the vertical optical coherence tomography (OCT) image at the initial visit into both-sides (n = 17) and one-side IRF (n = 33) groups, respectively. Multiple regression analyses demonstrated that not only the baseline logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) but also the IRF localization significantly correlated with the 12-month logMAR BCVA (p = 0.04 and p = 0.001, respectively), indicating that eyes with better baseline logMAR BCVA and one-side IRF have a significantly better visual prognosis in BRVO. The foveal ellipsoid zone band was significantly more disrupted (p < 0.001) in the both-sides IRF (47.1%) group than in the one-side IRF (3.0%) group. No eyes with decimal BCVA less than 0.5 were detected in the one-side IRF group at 12 months. Thus, baseline foveal IRF localization on vertical OCT images can be considered a novel biomarker for the visual prognosis of BRVO.

The study aimed to describe a case of rapid progression of polypoidal choroidal vasculopathy (PCV) following the third administration of the Pfizer-BioNTech (BNT162b2) mRNA vaccine. A 79-year-old Japanese man visited our hospital with a 1-week history of blurred vision in the left eye 16 h following the administration of the third BNT162b2 mRNA vaccine. The clinical examinations and imaging tests revealed massive submacular hemorrhage (SMH) and excessive subretinal fluid (SRF), owing to PCV in the left eye. No ocular abnormality was observed in the right eye. His medical history included diabetes and ocular history included cataracts, nonproliferative diabetic retinopathy, glaucoma in both eyes, and irregular retinal pigment epithelium elevation in the left eye. Since he received a single intravitreal injection of aflibercept approximately 2 years ago for the treatment of diabetic macular edema in the left eye, the left eye was stable. We performed an intravitreal injection of bevacizumab and combined phacoemulsification with pars plana vitrectomy with gas, including subretinal injection of tissue plasminogen activator to displace the SMH. Thirteen days after the surgery, the SMH and SRF decreased. Although rare, mRNA COVID-19 vaccine administrations could be associated with PCV deterioration.

This study aimed to investigate the safety and efficacy of rapid primary phacoemulsification in patients with acute primary angle closure (APAC) (n = 41), with or without preoperative IOP-lowering medication. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of corneal endothelial cells (CECs), and number of IOP-lowering medications at the preoperative examination (Pre), postoperative day 1 (1d), week 1 (1w), and month 1 (1m) were used as indicators and compared. BCVA significantly improved at 1d, 1w, and 1m compared with Pre (p < 0.05) and significantly improved at 1m compared to 1d (p < 0.05) for all eyes. IOP significantly decreased at 1d, 1w, and 1m compared with Pre (p < 0.05). CECs were not significantly different between Pre and 1m; the number of IOP-lowering medications decreased significantly from Pre to 1m (p < 0.05). BCVA and IOP were not significantly different between the two groups for all periods. CECs were not significantly different between the two groups at Pre and 1m. Rapid primary phacoemulsification improved visual acuity due to improvement of corneal edema without central visual field defects and good IOP control without reoperation or IOP-lowering medication and maintained the number of corneal endothelial cells with or without preoperative IOP-lowering medication in patients with APAC.
