Three-year outcome of photodynamic therapy combined with VEGF inhibitor for pachychoroid neovasculopathy.

BACKGROUND: Long-term results of photodynamic therapy (PDT) combined with vascular endothelial growth factor (VEGF) inhibitors for pachychoroid neovasculopathy (PNV) are not yet clear. METHODS: This study is a retrospective, observational case series. We retrospectively examined untreated PNV cases (22 cases, 22 eyes, mean age of 71.0 years) who underwent PDT therapy in combination with VEGF inhibitors followed by additional treatments with pro re nata protocol. Visual acuity, number of treatments, and time to recurrence were examined. In addition, foveal choroidal thickness and choroidal vascularity index (CVI) were evaluated in 13 of 22 patients who were followed up with SpectralisOCTR from baseline. RESULTS: Fifteen (68%) cases had polyps at baseline. LogMAR visual acuity averaged 0.24 ± 0.20 (range, - 0.079 to 0.82) at baseline and significantly improved after 1, 2, and 3 years (p = 0. 004, 0.0003, 0.002, respectively). Fourteen patients (64%) recurred, with an average time to recurrence of 1.8 ± 0.9 years. Foveal choroidal thickness decreased significantly after 1 year (average from 326 µm to 263 µm) and remained unchanged up to 3 years (255 µm). CVI also decreased after 1 year (average from 0.62 to 0.61) and remained unchanged until 3 years later (0.60). CONCLUSIONS: We examined the 3-year course of PDT in combination with the VEGF inhibitor for untreated PNV. Visual acuity was improved, foveal choroidal thickness and CVI were decreased after 3 years.

Nonsurgical closure of full thickness macular hole under topical therapy in two eyes with pathologic myopia.

PURPOSE: Non-surgical closure of a full-thickness macular hole (FTMH) with eye drops has recently been reported, but there are few similar reports in cases with pathologic myopia. CASE PRESENTATION: (Case 1) The right eye of a 75-year-old female with an axial length of 28.83 mm had undergone anti-vascular endothelial growth factor (VEGF) treatment for choroidal neovascularization presented with FTMH. Topical betamethasone, bromfenac, and blinzolamide treatments were started, and the FTMH was closed with visual improvement (20/32 to 20/20) after 5 weeks. (Case 2) In the right eye of a 55-year-old male with an axial length of 30.81 mm and lacquer cracks, subretinal hyperreflective material and FTMH developed. The above three drugs were started after anti-VEGF drug injection. Sixteen weeks later, the FTMH was closed with visual improvement (20/63 to 20/20). CONCLUSION: Nonoperative closure of FTMH has already been reported, but few in eyes with pathologic myopia. Our results suggest that nonoperative closure of FTMH associated with pathologic myopia under eye drops may be possible in some cases.

Mound-like Epiretinal Material: Its Short-term Changes and Association with Posterior Vitreous Detachment.

PURPOSE: To describe clinical characteristics of a retinal finding termed mound-like epiretinal material (MOLEM), and distinguish it from epiretinal proliferation, a similar epiretinal finding previously described in various pathologies. METHODS: Five eyes from five patients were retrospectively identified from medical records. Clinical findings and images, including fundus photographs and optical coherence tomography (OCT), were reviewed. RESULTS: All eyes displayed mound-like material with uniform and low-to-moderate reflectivity on an otherwise intact retinal surface detected on OCT. No eyes presented with concurrent pathology typically observed in cases of epiretinal proliferation, such as lamellar/full-thickness macular hole, epiretinal membrane, vitreomacular traction, or uveitis. Two eyes exhibited central serous chorioretinopathy, but there was no association of MOLEM with serous retinal detachment. In three out of five eyes, MOLEM appeared simultaneously with posterior vitreous detachment (PVD). Some lesions underwent irregular transformations over months and occasionally disappeared. While all cases were monitored without intervention, no visual decline or complications attributed to MOLEM were detected. CONCLUSION: MOLEM represents a novel clinical finding, characterized by transient morphological changes without symptoms and potential association with PVD. It may occur in eyes lacking macular diseases linked with epiretinal proliferation, a similar yet distinct lesion. The incidence, etiology, and clinical significance of MOLEM warrant further investigation by accumulating comparable cases, although the lesion appears benign and self-limiting.

Biomechanical properties measured with dynamic Scheimpflug analyzer in central serous chorioretinopathy.

PURPOSE: Recent evidence suggests that venous congestion at the vortex vein significantly contributes to the development of central serous chorioretinopathy (CSCR), and sclera is observed to be thicker in affected eyes. This study aims to investigate whether eyes with CSCR exhibit stiff corneas, measured using Corneal Visualization Scheimflug Technology (Corvis ST), which may serve as an indicator of scleral stiffness. METHODS: This retrospective case-control study comprises 52 eyes from 33 patients diagnosed with CSCR and 52 eyes from 32 normal controls without CSCR. We compared biomechanical parameters measured with Corvis ST and anterior scleral thickness measured using anterior segment swept-source optical coherence tomography between the two groups. RESULTS: Age, sex, axial length, intraocular pressure, and central corneal thickness showed no significant differences between the two groups (p > 0.05, linear mixed model). Three biomechanical parameters-peak distance, maximum deflection amplitude, and integrated inverse radius-indicated less deformability in CSCR eyes compared to control eyes. The stress-strain index (SSI), a measure of stiffness, and anterior scleral thickness (AST) at temporal and nasal points were significantly higher in the CSCR eyes. SSI and AST were not correlated, yet both were significantly and independently associated with CSCR in a multivariate logistic regression model. CONCLUSIONS: Eyes affected by CSCR have stiffer corneas, irrespective of thicker scleral thickness. This suggests that stiffer sclera may play a role in the pathogenesis of CSCR.

Intravitreal anti-vascular endothelial growth factor and combined photodynamic therapy for pachychoroid neovasculopathy: long-term treatment outcomes.

PURPOSE: To examine the long-term visual outcomes after initial treatment with combined photodynamic therapy (PDT) or aflibercept treat-and-extend (TAE) monotherapy in patients with pachychoroid neovasculopathy (PNV). METHODS: Patients diagnosed with PNV, initially treated with PDT combined with anti-vascular endothelial growth factor (VEGF) or intravitreal aflibercept (IVA) monotherapy in the TAE protocol and followed up for at least 6 months, were included in the study. Medical records were retrospectively reviewed. Survival analysis was performed, in which deterioration in logMAR visual acuity by 0.1 or 0.3 is defined as "death." The annual number of treatments was also analyzed. Sub-analysis was performed on 33 patients diagnosed with PNV without polypoidal lesions. RESULTS: This study included 46 patients (23 in the initial combined PDT group and 23 in the IVA TAE group). Mean age, sex, mean baseline logMAR visual acuity, or duration of observation (3.6 ± 3.2 years vs. 3.1 ± 1.9 years) in both groups were comparable. As for visual outcome, no significant differences were found in survival analysis based on worsening of 0.1 or 0.3 logMAR (3-year survival; 26% vs. 26%, 91% vs. 90%, respectively). Meanwhile, the additional number of anti-VEGF injections per year was significantly lower in the initial combined PDT group than in the IVA TAE group (1.0 ± 1.3 vs. 4.1 ± 1.5, p < 0.0001). No significant differences were found in the number of additional PDTs per year (0.07 ± 0.20 vs. 0.02 ± 0.09, p = 0.27). Similar results were found in a sub-analysis of 33 patients without polyps. CONCLUSION: In the treatment of PNV, regardless of the presence of polyps, the long-term visual outcomes were similar between the initial combined PDT and IVA TAE monotherapy. However, the annual number of anti-VEGF injections was lower in the initial combined PDT group than in the aflibercept TAE group, whereas that of PDT was comparable.

Quantitative evaluation of corneal irregularity and scarring after infectious keratitis using anterior segment optical coherence tomography.

PURPOSE: Corneal scars after infectious keratitis lead to insufficient transparency and irregular astigmatism, affecting visual acuity; therefore, they should be accurately evaluated to estimate visual function. This study aimed to quantitatively evaluate corneal irregularity and scarring after infectious keratitis using anterior segment optical coherence tomography (AS-OCT). METHODS: This was an observational clinical study. We included patients who had corneal scarring after treatment of infectious keratitis between 2014 and 2021 at University of Tokyo Hospital. We retrospectively examined best spectacle-corrected visual acuity (BSCVA), average keratometric power, central corneal thickness (CCT), and four components of the Fourier harmonic analysis including spherical and asymmetry components, as well as regular astigmatism and higher-order irregularity. We included anterior and posterior corneal data and compared results with those of contralateral healthy eyes. Additionally, we quantitatively evaluated the densitometry of the cornea obtained using AS-OCT. RESULTS: A total of 122 eyes of 61 patients were examined; male predominance was observed (n = 37), and the mean patient age was 55.3 ± 19.4 years. Comparisons with contralateral healthy eyes showed that BSCVA worsened (0.30 ± 0.83 and 0.93 ± 1.36 logMAR, respectively, P = 0.003), and CCT (531.1 ± 46.2 and 591.8 ± 132.4 µm, respectively, P < 0.001) and corneal densitometry (84.4 ± 11.8 and 111.9 ± 19.2 grayscale units, respectively, P < 0.001) increased significantly in affected eyes. The asymmetry component and higher-order irregularities that were not corrected with spectacles significantly increased (both P < 0.001), and there were no significant differences in the changes among the bacterial, fungal, herpetic, and acanthamoeba types of keratitis. CONCLUSION: Corneal scarring persisted after treatment for infectious keratitis, and the asymmetry and irregularities of corneal astigmatism increased as visual acuity deteriorated. AS-OCT with the Fourier harmonic analysis was useful for evaluating corneal topographic changes in patients with corneal scarring after keratitis.

Long-term visual outcomes in pachychoroid spectrum diseases and its associating factors of eyes with chronic central serous chorioretinopathy.

To analyze the long-term visual outcomes of pachychoroid spectrum diseases (PSD). Retrospective study. We reviewed the medical charts of consecutive patients with PSD, including focal choroidal excavation (FCE), pachychoroid pigment epitheliopathy (PPE), central serous chorioretinopathy (CSC), and pachychoroid neovasculopathy (PNV). The patients initially visited the Tokyo University Hospital from January 2008 to March 2021. Survival analyses were performed, in which loss of vision was defined as visual acuity (VA) of 0.2 logarithm of minimal angle of resolution (logMAR) or worse, 0.5 logMAR or worse, or VA worsening by 0.3 logMAR or greater. Moreover, we further investigated factors associated with visual prognosis, particularly in the CSC group. A total of 741 eyes of 638 patients were included in this analysis. The CSC or PNV group showed significantly worse visual prognosis than the FCE&PPE group for VA to 0.2 logMAR or worse (P = 0.0117 or 0.0001, respectively) and for VA worsening by 0.3 logMAR or greater (P = 0.0283 or 0.0037, respectively). In the CSC group, unlike age, sex, or treatment history, the accumulative duration of subfoveal fluid existence ≥ 12 months (continuous or intermittent) was significantly associated with visual prognosis (P < 0.0001). Among PSD, CSC and PNV were associated with a higher risk of vision loss in the long term than FCE and PPE. The duration of subretinal fluid existence was identified as a significant factor affecting long-term visual outcomes in CSC.

Epikeratophakia for Keratoconus: A Case Report with 30 Years of Follow-Up.

Background: Epikeratophakia is a refractive surgical procedure used to correct aphakic eyes, hyperopia, and keratoconus and is often performed in children. In this report, we present the long-term effects of epikeratophakia on the progression of keratoconus in a patient who underwent surgery. Case Presentation. The patient was a 17-year-old boy with keratoconus who had difficulty wearing hard contact lenses. As a solution, he underwent right eye epikeratophakia with a plano-powered lenticule. We followed up the patient for 30 years. Although the progression of keratoconus ceased in the operated eye, it continued in the nonoperated left eye and resulted in acute hydrops 9 years and 10 months after surgery. Subsequently, 20 years after the operation, anterior-segment optical coherence tomography was performed, which revealed that the progression of keratoconus had been interrupted in the right eye but had continued in the left eye, as evidenced by the parameters of the average and maximum keratometry and thinnest corneal thickness. Conclusions: Herein, we reported the longest follow-up to date of a case of keratoconus, in which one eye was treated with epikeratophakia. The progression of keratoconus was halted in the treated eye but continued in the nonoperated contralateral eye.

UbiA prenyltransferase domain-containing protein 1 (UBIAD1) variant c.695 A > G identified in a multigenerational Japanese family with Schnyder corneal dystrophy.

PURPOSE: We aimed to identify pathogenic variations in the UbiA prenyltransferase domain-containing protein 1 (UBIAD1) gene in a Japanese family with Schnyder corneal dystrophy (SCD). STUDY DESIGN: Clinical study METHODS: Three clinically diagnosed SCD patients from a single pedigree participated. Patients 1 and 2 were 69- and 65-year-old sisters, and patient 3 was the 42-year-old daughter of patient 1. Blood samples from the patients were obtained for genetic analysis. Mutation screening of the two UBIAD1 exons was performed using polymerase chain reaction (PCR)-based DNA sequencing. RESULTS: All participants were found to be heterozygous for the pathogenic missense variation c.695 A > G (p.Asn232Ser) in exon 2 of UBIAD1. CONCLUSION: This is the first report on the pathogenic UBIAD1 variation c.695 A > G (p.Asn232Ser) in a Japanese population. SCD is a rare corneal dystrophy, and further research on additional cases will aid in the elucidation of disease mechanisms and development of therapeutic strategies.

Intravenous lipo-prostaglandin E1 administration for patients with acute central retinal artery occlusion.

OBJECTIVE: This study aimed to investigate the anatomical and functional changes in patients with central retinal artery occlusion (CRAO) (n=21) treated with 10 µg/day intravenous liposomal prostaglandin E1 (lipo-PGE1). METHODS AND ANALYSIS: We used best-corrected visual acuity (BCVA), central retinal thickness with spectral domain optical coherence photography, optical intensity ratio (OIR) with imageJ software and retinal vessel diameter with fundus photography as indicators. Data were analysed using Tukey's multiple comparisons, Wilcoxon test or Spearman's correlation analysis as appropriate. RESULTS: BCVA was significantly improved at 1 month and 3 months after the initial visit (from 2.18±0.60 to 1.54±0.84 and 1.53±0.88, p=0.030 and p=0.027, respectively). The ratio of retinal vein diameter to optic disc diameter increased in the first month (from 0.40%±0.13% to 0.52%±0.16%, p=0.005). In addition, the OIR at the initial visit was significantly correlated with BCVA at 3 months (p=0.006, r=0.58). No severe adverse effects were observed. CONCLUSION: The results showed that visual acuity and retinal vein constriction improved after lipo-PGE1 therapy. In addition, the OIR in the initial phase can be an indicator of visual prognosis after treatment with PGE1 in patients with CRAO.

Corneal irregularity and visual function using anterior segment optical coherence tomography in TGFBI corneal dystrophy.

The purpose of this study was to evaluate corneal irregular astigmatism of patients with granular and lattice corneal dystrophy (GCD and LCD). 70 GCD, 35 LCD, and 81 control eyes were included. Anterior and posterior corneal topographic data obtained from anterior segment optical coherence tomography were expanded into four components via Fourier harmonic analysis. These components were compared with healthy eyes and the association between each component and best-corrected visual acuity (BCVA) was investigated. Anterior and posterior components increased in both GCD and LCD eyes. Anterior and posterior components of GCD2, anterior of LCD type 1 (LCD1), posterior of LCD type IIIA (LCD 3A), and type IV (LCD4) significantly increased. BCVA was significantly associated with anterior and posterior components in LCD eyes but not in GCD. The anterior components of LCD1, anterior and posterior of LCD3A, and posterior of LCD4 , were positively correlated with BCVA. As conclusions, in GCD eyes, anterior and posterior components differed from those of the control but BCVA was not significantly associated with them. In LCD eyes, the anterior and posterior components increased, and BCVA was significantly associated with the anterior and posterior components.

LOCATIONAL AGREEMENT OF NEAR-INFRARED AUTOFLUORESCENCE WITH CHOROIDAL VASCULAR HYPERPERMEABILITY IN CENTRAL SEROUS CHORIORETINOPATHY.

PURPOSE: To characterize the findings of eyes with choroidal vascular hyperpermeability (CVH), a hallmark of central serous chorioretinopathy, using multimodal imaging and investigate the locational agreement between these findings and CVH. METHODS: Among patients with central serous chorioretinopathy in either eye, eyes with CVH identified using indocyanine green angiography without exudative changes were included. All eyes were examined using funduscopy, fluorescein angiography, spectral-domain optical coherence tomography, and short-wavelength or near-infrared autofluorescence (SWAF or NIRAF). The locational agreement between CVH and imaging findings was evaluated for each modality. The relative index on how they overlapped was calculated as the overlapping index. Binarized images, particularly for NIRAF, were also evaluated. RESULTS: This study included 69 CVH sites in 33 eyes of 28 patients. Pachydrusen was detected in 36% of CVH sites. Fluorescein angiography revealed hyperfluorescent areas in 39% of CVH sites. Optical coherence tomography findings identified 65% of CVH sites, but the overlapping index was 5%. Short-wavelength or near-infrared autofluorescence imaging identified 89% of CVH sites, but they exhibited variable autofluorescence. NIRAF imaging revealed hypoautofluorescence findings in all CVH sites. When binarized, near-infrared autofluorescent dark dots were observed in all CVH sites. Overlapping indices before and after binarization were 78% and 98%, respectively. The near-infrared autofluorescent dark dots area corresponded well with that of CVH (intraclass correlation coefficient, 0.987 [95% confidence interval, 0.952-0.995]). CONCLUSION: Hypoautofluorescent findings revealed on NIRAF imaging, especially after binarization processing, corresponded well with CVH sites. These multimodal imaging results may help investigate the anatomical or locational characteristics of CVH in patients with central serous chorioretinopathy.

Association between retinal sensitivity and the presence of quiescent choroidal neovascularization in pachychoroid diseases.

This study was conducted to examine retinal sensitivity (RS) in eyes with pachychoroid diseases and to analyze its association with the presence or absence of quiescent choroidal neovascularization (CNV), that can be protective against retinal dysfunction or atrophy in other macular diseases such as age-related macular degeneration. A total of 12 eyes of 12 patients aged ≥45 years having the characteristic findings of central serous chorioretinopathy but not presenting any exudative changes were included in this study. Choroidal vascular hyper permeability (CVH) was identified by indocyanine green angiography, and the presence or absence of CNV was evaluated by optical coherence tomography angiography. RS at 68 points was examined by microperimetry. The average RS corresponding to within and outside CVH was compared. The association between the difference in RS and the presence or absence of CNV was also analyzed. CNV was detected in six eyes (50%). In eyes without CNV, the RS within CVH was similar compared with that outside CVH. However, in eyes with CNV, the RS within CVH was significantly decreased compared with that outside CVH. Multiple regression analysis revealed the presence of CNV as an independent factor associated with RS. In eyes with pachychoroid diseases, RS decreased within the CVH area under the coexistence of nonexudative CNV.

Impact of rigid gas-permeable contact lens on keratometric indices and corneal thickness of keratoconus eyes examined with anterior segment optical coherence tomography.

PURPOSE/AIM: Detecting keratoconus (KC) progression helps determine the surgical indication for corneal cross-linking (CXL). This retrospective observational study aimed to examine changes in keratometric indices and corneal thickness in patients with KC who used rigid gas-permeable (RGP) contact lenses. MATERIALS AND METHODS: This study involved 31 eyes (31 patients) diagnosed with KC. No patient had used RGP or any other type of contact lenses for at least 1 month. Corneal topographic data were obtained using three-dimensional anterior segment optical coherence tomography before and after >1 month of RGP lens use. RESULTS: The average and maximum keratometry values changed after using an RGP lens (-1.05 ± 1.92 D, p < 0.01 and -1.65 ± 4.20 D, p = 0.04, respectively); the spherical component of the anterior corneal surface became significantly smaller (p = 0.02). No change was observed in the central or thinnest corneal thickness values. Keratometric changes were greater in eyes with severe KC than in those with moderate KC (p = 0.014). CONCLUSIONS: Keratometry and spherical components of the anterior corneal surface values decreased after RGP lens use; keratometric changes were greater in eyes with severe KC than in those with moderate KC. Corneal progression indices, including corneal thickness, posterior keratometry, and irregular astigmatism values, mostly remained unchanged. It is important to consider these findings when evaluating corneal topography of KC and preparing CXL.

Spontaneous Corneal Graft Reattachment Following Descemet Stripping Automated Endothelial Keratoplasty in Prone Position: A Case Report and Literature Review.

Graft detachment after Descemet stripping automated endothelial keratoplasty (DSAEK) is usually managed with air-bubbling. However, it is an invasive procedure, which can cause corneal endothelial reduction, and requires hospitalization and supine position maintenance. Only few case reports on graft reattachment in the prone position exist, and this is the first report from Japan. An 87-year-old woman presented with sudden pain in her left eye. Examination of her left eye showed a best-corrected vision of 20/50, shallow anterior chamber, cataractous lens, central corneal thickness (CCT) of 630 µm, and corneal endothelial cell count of 467 cells/mm2. She was diagnosed with left-eye bullous keratopathy due to primary angle closure, and DSAEK was performed after cataract surgery. Post-surgery, she touched her left eye due to agitation. Graft adhesion was good until postoperative day 4; however, a partial detachment was observed on day 12. She was instructed to remain in a prone position for as long as possible; on day 22, the graft was reattached, and the CCT improved to 555 µm. Since then, the graft adhesion has been maintained, and her best-corrected vision has improved to 20/30. To date, 5 cases of graft reattachment in the prone position have been reported, with reattachment observed in all cases within 10 days from the onset of detachment, including this case. Re-bubbling is an effective technique; however, it is invasive and may cause additional corneal endothelial loss. Therefore, it may be beneficial to have the patient initially attempt the prone position for reattachment.

Corneal Graft Rejection after Descemet's Membrane Endothelial Keratoplasty with Peripheral Anterior Synechiae.

Descemet's membrane endothelial keratoplasty (DMEK) for patients with corneal endothelial loss rarely results in graft rejection. Herein, we report a rare case of graft rejection following DMEK, in which peripheral anterior synechiae were observed postoperatively. A 66-year-old woman was referred to our hospital after complaints of decreased visual acuity of her right eye after laser iridotomy for primary angle closure 3 years earlier. Her right cornea had bullous keratopathy with mild cataract, and her best-corrected visual acuity (BCVA) was 20/40. After cataract surgery, DMEK was successfully performed, except for development of peripheral anterior synechiae at the temporal cornea. Her BCVA recovered to 20/20. However, when topical instillation was changed to 0.1% fluorometholone from 0.1% betamethasone once a day, corneal edema reappeared with hyperemia, mutton fat keratic precipitates (KPs), and cells in the anterior chamber. The BCVA worsened to 20/32. Graft rejection was diagnosed, and subconjunctival injection of dexamethasone was performed 3 times, once every few days, with 0.1% topical betamethasone instillation. Subsequently, the hyperemia, mutton fat KPs, and cells in the anterior chamber disappeared with a recovered BCVA of 20/20 after 2 weeks. Ten months after graft rejection, there was no recurrence of intraocular inflammation, and only topical betamethasone was administered twice daily. It is important to exercise caution in cases with peripheral anterior synechiae after DMEK. Long-term steroid administration is necessary to prevent graft rejection.

Iridotrabecular and Iridocorneal Contact Changes after Cataract Surgery and Endothelial Keratoplasty in Bilateral Iridoschisis.

We report a case of bilateral iridoschisis with corneal oedema and a quantitative evaluation of the changes in iridotrabecular and iridocorneal contact before and after cataract surgery and after Descemet stripping automated endothelial keratoplasty (DSAEK). A 76-year-old woman with iridoschisis and cataracts, previously managed with laser iridotomy, experienced progressive vision loss. The preoperative iridotrabecular contact (ITC) index measured by anterior segment optical coherence tomography was 23.6% in the right eye and 24.4% in the left eye. Preoperative corneal oedema in the right eye was more severe than that in the left eye. Cataract surgery, followed by DSAEK, was performed in the right eye and subsequently in the left eye. Her visual acuity improved postoperatively, and the corneal oedema of both eyes was treated successfully. Moreover, the ITC index improved in both eyes, to 4.7 and 6.9% after cataract surgery and to 0 and 0% after DSAEK in the right and left eyes, respectively. Staged cataract surgery and DSAEK were effective for endothelial decompensation caused by iridoschisis. Additionally, we confirm that iridotrabecular and iridocorneal contacts improved after both surgical procedures not only after cataract surgery but also after DSAEK. This case report showed the clinical usefulness of the ITC index in the detection of changes after different surgical procedures.

Association of Near-Infrared and Short-Wavelength Autofluorescence With the Retinal Sensitivity in Eyes With Resolved Central Serous Chorioretinopathy.

Purpose: The purpose of this study was to compare the results of near-infrared autofluorescence (NIRAF) and short-wavelength autofluorescence (SWAF) imaging of eyes with resolved central serous chorioretinopathy (CSC) and to assess the retinal sensitivity (RS) in areas with abnormal autofluorescence (AF) using white-on-white (WW) and blue-on-yellow (BY) perimetries. Methods: We examined 20 consecutive eyes with resolved CSC. We calculated the areas of abnormal AF detected by SWAF and NIRAF imaging as SWAF_area and NIRAF_area, respectively, and the number of measurement points within and outside abnormal SWAF and NIRAF regions were counted. The results of WW and BY perimetries were superimposed on the AF images, and the mean overall RS within and outside abnormal SWAF and NIRAF regions were calculated using both WW and BY perimetries (W-RSin_SWAF, W-RSout_SWAF, W-RSin_NIRAF, W-RSout_NIRAF, B-RSin_SWAF, B-RSout_SWAF, B-RSin_NIRAF, and B-RSout_NIRAF, respectively). Results: The mean age of the participants was 54.1 years. The SWAF_area was significantly smaller than the NIRAF_area (P < 0.0001, Wilcoxon signed rank test). A χ2 test suggested a significant relationship between the number of measurement points within/outside abnormal SWAF and NIRAF regions (P < 0.0001). In the results of measurement by WW perimetry, there was a significant difference between W-RSin_NIRAF and W-RSout_NIRAF (P < 0.0001), but not between W-RSin_SWAF and W-RSout_SWAF (P = 0.060, Wilcoxon rank sum test). In contrast, on BY perimetry, there were significant differences between both B-RSin_SWAF and B-RSout_SWAF and between B-RSin_NIRAF and B-RSout_NIRAF (P < 0.0001). Conclusions: NIRAF was useful for predicting impaired RS in eyes with resolved CSC.

Rapidly Changing Serous Detachment During BRAF and MEK Inhibitor Therapy.

We report a case of rapidly changing serous retinal detachment (SRD) during melanoma therapy with a combination of encorafenib, a serine/threonine-protein kinase B-Raf (BRAF) inhibitor, and binimetinib, a mitogen-activated protein kinase (MEK) inhibitor. A 50-year-old woman with metastatic melanoma presented with a sudden visual blur. She had been treated with encorafenib (450 mg every morning) and binimetinib (45 mg every 12 hours) after surgery for four months. Ophthalmological examination revealed bilateral SRD, but it was completely resolved after two hours. Visual acuity was normal in each eye. Encorafenib and binimetinib were continued. Shallow SRD appeared again five months later, but it resolved in two months. MEKAR typically occurs shortly after the start of an administration, and its development after several months was very little known. Continued examination for ophthalmic events should be considered.

Does the number of laser applications for ROP treatment influence the degree of myopia?

PURPOSE: To evaluate the relationship between the number of laser shots applied during laser photocoagulation treatment and the degree of myopia at 3 years in children with laser-treated retinopathy of prematurity (ROP). METHOD: A total of 68 eyes of 34 infants who had developed prethreshold ROP and were treated by diode laser therapy were included in the current study. Cycloplegic retinoscopic refraction testing was performed in the children at the age of 3 years, and the spherical equivalent (SE) was calculated for all the examined eyes. The number of laser shots that had been applied was compared between the eyes with and without high myopia (SE < - 5 diopters (D)). In addition, the relationship between the difference in the SE values between the two eyes in each infant and the difference in the number of laser shots applied between the two eyes was also analyzed. RESULTS: The number of laser shots applied was significantly higher for the eyes with high myopia than for those without high myopia (p = 0.0088), and the number of laser shots applied was significantly positively correlated with the degree of myopia (p < 0.001). A significant correlation was also observed between the differences in the SE values between the two eyes and the differences in the number of laser shots applied between the two eyes (p = 0.0013). CONCLUSION: The number of laser shots applied in photocoagulation treatment for ROP is significantly associated with the degree of myopia seen subsequently in the children.
