Language：English Publishing type：Research paper (scientific journal)

To investigate the effectiveness of a treat-and-extend regimen (TAE) of intravitreal ranibizumab injections (IVR) for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively examined 35 eyes of 35 patients with ME due to BRVO who underwent TAE for 1 year. Patients whose treatment interval extended to 12 weeks were switched to a pro re nata regimen (PRN; TAE to PRN group), while TAE was continued for patients whose treatment interval was less than 12 weeks (continued TAE group). Changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and predictive factors for inclusion in the TAE to PRN group were analyzed. BCVA and CRT both improved significantly at 1 year compared with baseline (p<0.001). Sixteen eyes (45.7%) were included in the TAE to PRN group, while 19 eyes (54.3%) were included in the continued TAE group. BCVA in the TAE to PRN group was significantly better than that in the continued TAE group at 1 year (p=0.047). BCVA at baseline and macular BRVO were significant predictive factors for inclusion in the TAE to PRN group. TAE was effective for improving BCVA and CRT. The TAE to PRN group showed significantly better prognosis.

Language：English Publishing type：Research paper (scientific journal)

Traumatic eyeball luxation is a rare clinical condition with a dramatic presentation. Here, we describe a unique case of traumatic globe luxation and complete optic nerve transection caused by heavy object compression. A 45-year-old male automobile mechanic was injured when a truck slipped from its supports, crushing his head and face. On arrival, his right eyeball was obviously displaced anteriorly and he had no light perception. Computed tomography revealed complex frontal bone and facial fractures with underlying brain contusion in addition to complete transection of the right optic nerve. The patient was successfully treated using a multidisciplinary approach.

Language：English Publishing type：Research paper (scientific journal)

Contradictory data have been presented regarding the implication of the NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome in age-related macular degeneration (AMD), the leading cause of vision loss in the Western world. Recognizing that antibody specificity may explain this discrepancy and in line with recent National Institutes of Health (NIH) guidelines requiring authentication of key biological resources, the specificity of anti-NLRP3 antibodies was assessed to elucidate whether non-immune RPE cells express NLRP3. Using validated resources, NLRP3 was not detected in human primary or human established RPE cell lines under multiple inflammasome-priming conditions, including purported NLRP3 stimuli in RPE such as DICER1 deletion and Alu RNA transfection. Furthermore, NLRP3 was below detection limits in ex vivo macular RPE from AMD patients, as well as in human induced pluripotent stem cell (hiPSC)-derived RPE from patients with overactive NLRP3 syndrome (Chronic infantile neurologic cutaneous and articulate, CINCA syndrome). Evidence presented in this study provides new data regarding the interpretation of published results reporting NLRP3 expression and upregulation in RPE and addresses the role that this inflammasome plays in AMD pathogenesis.

【黄斑疾患の新しい概念と治療法】黄斑疾患に対する手術手技の新展開内境界膜処理と網膜下注入

森實祐基

日本の眼科 89 ( 1 ) 39 - 44 2018.1

Language：Japanese Publisher：(公社)日本眼科医会

近年、黄斑に対する手術手技について、新たな発想に基づいて手技のバリエーションが生まれる、これまで手技の対象ではなかった疾患が対象となる、といった展開がみられている。例えば黄斑円孔に対して、これまでは内境界膜の剥離除去が行われてきた。しかし、特殊な黄斑円孔に対しては、内境界膜を剥離除去するだけでは円孔が閉鎖しないことが明らかになり、内境界膜弁翻転法や内境界膜自家移植が考案され普及してきている。現時点では、このような新しい黄斑手技の方法や適応は厳密には定まっておらず、術者の経験や好みに基づいて施行されている。今後、手技や適応の標準化に向けた検討が必要である。(著者抄録)

PURPOSE: To investigate the influence of subretinal injection pressure on the microstructure of the retina in a monkey model. METHODS: After vitrectomy, balanced salt solution was injected subretinally into one eye each of four cynomolgus monkeys while controlling the injection pressure. Initially, a pressure of 2 psi was used, and this was gradually increased to determine the minimum required pressure. Subsequent injections were performed at two pressures: minimum (n = 13) and high (n = 6). To compare the influence of these injection pressures on retinal structure, optical coherence tomography (OCT) was performed before surgery and every week afterwards. The monkeys were euthanized and their eyes were enucleated at 1 or 6 weeks after the injections. The eyes were processed for light microscopy and transmission electron microscopy (TEM) as well as for TdT-mediated dUTP nick end labeling. RESULTS: The minimum pressure required to perform subretinal injection was 6 psi. After injection at this pressure, both OCT and microscopy showed that the retinal structure was well-preserved throughout the experimental period at all injection sites. Conversely, after injection at high pressure (20 psi) OCT images at all injection sites showed disruption of the ellipsoid zone (EZ) after 1 week. Microscopy indicated damage to the photoreceptor outer segment (OS) and stratification of the retinal pigment epithelium (RPE). After 6 weeks, OCT demonstrated that the EZ had become continuous and TEM confirmed that the OS and RPE had recovered. Photoreceptor apoptosis was absent after subretinal injection at both pressures. CONCLUSIONS: The retinal damage caused by subretinal injection increases depending on pressure, indicating that clinicians should perform subretinal injection at pressures as low as possible to ensure safety.

Language：English Publishing type：Research paper (scientific journal)

PURPOSE: To compare the success rates of eye drop instillation in the sitting position and supine position among Japanese patients with ocular diseases (cataract, glaucoma, or retinal and vitreous diseases). METHODS: Patients who were hospitalized in Okayama University Hospital for eye surgery were studied. Instillation procedures of each patient in both the sitting and supine positions were recorded using a video camera at the time of instillation. We defined "success" when one drop fell accurately onto the ocular surface at the first attempt. Instillation of two or more drops, drops delivered to a site other than the eye surface, and touching the eyelashes, eyelids, or conjunctiva with the tip of the eye drop bottle were regarded as "failure". We excluded patients with vision below counting finger. RESULTS: One-hundred and two patients (54 males and 58 females, aged 70.2 ± 12.3 years) with ocular disease who were hospitalized for surgery (cataract: 61.8%, glaucoma: 15.7%, retinal and vitreous diseases: 22.5%) were included in this prospective observational study. The mean duration of eye drop use was 3.1 ± 5.2 years. The success rate of eye drop instillation was significantly higher in the supine position than in the sitting position (64.7% vs. 50%, P = 0.0039). The mean age was significantly higher in the failure group than in the success group (74.0 ± 11.5 vs. 67.7 ± 12.4 years, P = 0.0085) for the sitting position, but not significantly different for the supine position (72.3 ± 12.9 vs. 70.1 ± 12.0 years, P = 0.3849). No significant differences in mean duration of drop use, mean corrected VA, and mean spherical equivalent refraction were observed between success and failure groups, for both sitting and supine positions. CONCLUSIONS: In the present study, the success rate of eye drop instillation was significantly higher when applied in the supine position than in the sitting position.

Acta medica Okayama 71 ( 6 ) 539 - 542 2017.12

Language：English

Internal limiting membrane (ILM) peeling is an important maneuver in vitrectomy for macular holes (MHs). A nitinol loop is a surgical instrument designed to create an edge on the ILM and peel the ILM safely and consistently. The effect of using a nitinol loop for ILM peeling on the retina is not clear. We report here on a case of an idiopathic full-thickness MH in an adult woman, in whom retinal damage was revealed after her ILM was peeled using a nitinol loop.

Japanese journal of ophthalmology 61 ( 6 ) 472 - 478 2017.11

Language：English Publishing type：Research paper (scientific journal)

PURPOSE: To investigate the effectiveness of displacement of submacular hemorrhage (SMH) caused by polypoidal choroidal vasculopathy (PCV) by assessing retinal sensitivity using microperimetry. METHODS: We retrospectively reviewed the medical records of 11 consecutive PCV patients with SMH. All patients underwent vitrectomy, subretinal injection of tissue plasminogen activator, and fluid-air exchange, followed by antivascular endothelial growth factor therapy using a pro re nata regimen. The retinal sensitivity was measured by use of microperimetry before and after surgery. RESULTS: The mean (SD) age of the patients was 74.1 ± 9.4 years. The mean SMH diameter was 6.8 ± 5.2 disc diameters. The best-corrected visual acuity (BCVA), mean retinal sensitivity, and mean number of measure points with a sensitivity ≥10 dB before the surgery were 0.94 ± 0.49, 4.2 ± 4.5 dB, and 15.6 ± 15.1 points, respectively. These had significantly improved 6 months after surgery (0.39 ± 0.37, 15.6 ± 7.3 dB, and 50.9 ± 22.2 points, respectively; P < 0.05 for all outcome measures). The mean number of measure points with an absolute scotoma before surgery had decreased significantly 6 months after surgery (from 40.5 ± 15.0 to 9.4 ± 16.0 points; P < 0.001). CONCLUSIONS: Displacement of SMH effectively improves retinal sensitivity as well as BCVA.

Investigative ophthalmology & visual science 58 ( 11 ) 4847 - 4855 2017.9

Language：English Publishing type：Research paper (scientific journal)

Purpose: To investigate the mechanism of macular hole (MH) closure following the inverted internal limiting membrane (ILM) technique. Methods: We performed the inverted ILM flap surgical technique as an experimental MH model in monkeys, and investigated the process of MH closure immunohistochemically. We then investigated the effects of type IV collagen, fibronectin, and laminin, which are constituent proteins of the ILM, on the proliferation and migration of cultivated Müller cells (MIO-M1). We also investigated the expression of neurotrophic factors and basic fibroblast growth factor (bFGF) in human ILM and MIO-M1 cells, and the effect of MIO-M1 migration on the expression of these factors, via immunohistochemical staining and the real-time reverse transcription polymerase chain reaction. Results: Ten days after inverted ILM flap surgery, the MH had closed and proliferating glial fibrillary acidic protein (GFAP)-positive cells surrounded the ILM. Type IV collagen, fibronectin, and laminin all enhanced the proliferation of MIO-M1 cells, and type IV collagen and fibronectin enhanced the migration of MIO-M1 cells. Neurotrophic factors and bFGF were present on the surface of the human ILM, and MIO-M1 cells produced these factors. Neurotrophic factors and bFGF were expressed to a significantly greater extent by migrating MIO-M1 cells than by these cells in their static state. Conclusions: During MH closure, the ILM functioned as a scaffold for the proliferation and migration of Müller cells, and may promote Müller cell activation. Neurotrophic factors and bFGF produced by activated Müller cells and present on the surface of the ILM may contribute to MH closure.
