1. Validation of an Artificial Intelligence-based Tool - The Screening Corneal Objective Risk of Ectasia Integrated into Anterion for Detection of Corneal Ectasia/Risk of Ectasia.
PMID:日期:2024-12-02The purpose of this study was to validate the artificial intelligence-based Screening Corneal Objective Risk of Ectasia (SCORE) for the detection of corneal ectasia/risk of ectasia and to find the mean SCORE value in normal eyes. This prospective observational study included 320 eyes of 160 patients undergoing screening for refractive surgery and keratoconus. All were subjected to Anterion (Heidelberg, Germany) corneal tomography. The maps were read by trained cornea specialists masked with respect to system-generated SCORE. The SCORE values were retrieved by another masked observer. The SCORE was labeled true positive if the eye was tomographically positive for ectasia/ risk of ectasia with or without clinical evidence of ectasia (i.e., clinician's diagnosis as ectasia/ risk of ectasia) and SCORE was >/=0. The SCORE test was labeled as true negative if all the maps were normal and SCORE was <0. A false-positive test was where the eye was normal but SCORE was ≥0. A false-negative test was one tomographically there was definite evidence of ectasia/ risk; with or without clinical evidence of ectasia (i.e.,clinician's diagnosis as ectasia/ at risk of ectasia) but SCORE was <0. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. The mean SCORE in normal eyes was -0.7 ± 0.6. Sensitivity was 83.3% and specificity was 80%. PPV and NPV were 46% and 96% respectively. In the keratoconus subgroup, specificity and PPV were 100%; sensitivity was 79% and NPV was 76.3%. SCORE in Anterion has moderate sensitivity and specificity for detection of ectasia/risk of ectasia. It performs best in the detection of corneal ectasia. It needs to be interpreted with caution.

2. Intravitreal Aflibercept for Diffuse Choroidal Hemangioma in Sturge-Weber Syndrome.
PMID:日期:2024-12-02A 16-year-old female with Sturge-Weber syndrome (SWS) presented with decreased vision in the left eye (20/100). Examination and multimodal imaging showed diffuse choroidal hemangioma with choroidal neovascularization and macular edema. Treatment with three monthly injections of intravitreal aflibercept improved vision by 4 lines with complete resolution of the macular edema sustained 4 months after the last injection. A review of the literature showed that this is the first report of successful use of aflibercept to treat macular edema and choroidal neovascularization associated with diffuse choroidal hemangioma in SWS. We suggest that early antivascular endothelial growth factor injections should be considered when faced with choroidal neovascularization associated with diffuse choroidal hemangiomas.

3. Evaluation of Macula and Optic Disc of Adult Amblyopia Patients with Diverse Etiologies using Optical Coherence Tomography Angiography.
PMID:日期:2024-12-02To compare macula and optic-disc optical coherence tomography angiography (OCTA) metrics of adult amblyopic eyes with healthy controls and investigate whether these differ according to amblyopia etiology. This cross-sectional study included 35 unilateral amblyopic adults ( = 35 eyes) and 35 age-matched healthy controls ( = 35 eyes). Amblyopia subgroups consisted of anisometropic ( = 12 eyes), strabismic ( = 12 eyes), and combined-mechanism amblyopia ( = 11 eyes). Foveal avascular zone area (FAZA), vessel density (VD), and retinal thickness were obtained using OCTA. Retinal thicknesses were measured at the fovea, parafovea, perifovea, and retinal nerve fiber layer. Foveal, parafoveal, perifoveal, whole-macula, intradisc, peripapillary, and whole-disc VD were recorded. Groups were compared regarding OCTA metrics after adjusting for axial length, spherical equivalent, age, gender, and signal quality index using a one-way analysis of covariance test. Amblyopic eyes had significantly lower foveal, parafoveal, perifoveal, whole-macula VD in superficial capillary plexus (SCP), and deep capillary plexus (DCP) than control eyes after adjusting for confounders ( < 0.05 for all). All amblyopia subgroups had significantly lower parafoveal, perifoveal, and whole-macula VD in SCP and DCP than control eyes after adjusting for confounders ( < 0.05 for all). There was no significant difference in retinal thickness, FAZA, intradisc VD, peripapillary VD, and whole-disc VD between amblyopic and control eyes, as well as amblyopia subgroups and control eyes. These results suggest that effect of amblyopia on macular microvasculature should be considered when interpreting OCTA metrics of adults with concomitant diseases. It also supports that adult amblyopic eyes of different etiology have similar microvascular features.

4. Severe Psoriasiform Blepharitis Accompanying with Phthisis Bulbi.
PMID:日期:2024-12-02The aim of this study is to present a case of severe chronic blepharitis secondary to psoriasis in an eye that developed phthisis bulbi during the treatment of juvenile glaucoma. A 19-year-old male patient, who had been treated for bilateral juvenile glaucoma for many years and had phthisis bulbi in his left eye for the last 4 years, presented with the complaint of chronic eyelid inflammation in the same eye for 2 years. Examination revealed hyperemia, discharge, scaling, inflammation, and diffuse edema on the lower and upper eyelids. It was determined that she had been diagnosed with psoriasis by the dermatology clinic 3 years before her history. Psoriasis-like hyperplasia was observed in the lower eyelid biopsy. He was treated with topical periocular low potency steroid ointment (1% hydrocortisone). Clinicians should be vigilant about eyelid and eye involvement in psoriasis.

5. Comparison of Corneal Tomography Parameters in the Diagnosis of Keratoconus in Early and Late Pediatric Age Group.
PMID:日期:2024-12-02The purpose of this study was to examine demographic and tomographic parameters in pediatric patients diagnosed with keratoconus and to evaluate the difference between early and late age periods. This retrospective study included patients younger than 18 years of age who were diagnosed with keratoconus. All examination findings, demographic data, tomography parameters, and keratoconus stages were recorded. The patients were divided into two groups: 14 years or younger (Group 1) and those between 14 and 18 years old (Group 2). All corneal tomography parameters were compared in the subgroups and were evaluated statistically. <0.05 was considered statistically significant. A total of 131 eyes of 71 patients were included. The mean age was 15.7 ± 1.8 (range, 10-18) years, and the female-to-male ratio was 23/48. The mean best spectacle-corrected visual acuity was 0.36 ± 0.44 (range, 0-3.1) logMAR. The averages of K1, K2, Km, and Kmax were 49.0 ± 6.2 (range, 39.6-74.5) D, 53.5 ± 7.0 (range, 43.3-76.8) D, 51.3 ± 6.5 (range, 41.5-75) D, and 59.1 ± 9.0 (range, 44.7-85.2) D, respectively, and the mean central corneal thickness (CCT) was 456.9 ± 63.5 µm (range, 261-601). The distribution of eyes with keratoconus from stages 1-4 was 5.3%, 36.6%, 38.9%, and 19.1%, respectively. When the groups were compared, K1, K2, Km, and Kmax were significantly steeper in Group 1 compared to Group 2 ( = 0.006, = 0.004, = 0.004, and = 0.007, respectively). CCT and the thinnest corneal thickness values were significantly less in Group 1 ( = 0.038 and = 0.041, respectively). The decision for treatment - especially cross-linking - should be made at the right time due to the increased risk of progression in the earlier ages in pediatric keratoconus population.

6. Applications of Artificial Intelligence in Choroid Visualization for Myopia: A Comprehensive Scoping Review.
6. 人工智能在近视脉络膜可视化中的应用：综合范围综述PMID:日期:2024-12-02Numerous artificial intelligence (AI) models, including deep learning techniques, are being developed to segment choroids in optical coherence tomography (OCT) images. However, there is a need for consensus on which specific models to use, requiring further synthesis of their efficacy and role in choroid visualization in myopic patients. A systematic literature search was conducted on three main databases (PubMed, Web of Science, and Scopus) using the search terms: "Machine learning" OR "Artificial Intelligence" OR "Deep learning" AND "Myopia" AND "Choroid" OR "Choroidal" from inception to February 2024 removing duplicates. A total of 12 studies were included. The populations included myopic patients with varying degrees of myopia. The AI models applied were primarily deep learning models, including U-Net with a bidirectional Convolutional Long Short-Term Memory module, LASSO regression, Attention-based Dense U-Net network, ResNeSt101 architecture training five models, and Mask Region-Based Convolutional Neural Network. The reviewed AI models demonstrated high diagnostic accuracy, including sensitivity, specificity, and area under the curve values, in identifying and assessing myopia-related changes. Various biomarkers were assessed, such as choroidal thickness, choroidal vascularity index, choroidal vessel volume, luminal volume, and stromal volume, providing valuable insights into the structural and vascular changes associated with the condition. The integration of AI models in ophthalmological imaging represents a significant advancement in the diagnosis and management of myopia. The high diagnostic accuracy and efficiency of these models underscore their potential to revolutionize myopia care, improving patient outcomes through early detection and precise monitoring of disease progression. Future studies should focus on standardizing AI methodologies and expanding their application to broader clinical settings to fully realize their potential in ophthalmology.

7. Variation of Ambient Illumination Across Different Locations: An Impact on Antimyopia Strategy.
PMID:日期:2024-12-02To evaluate whether the level of ambient illumination in winter at different locations, time of a day, sun protection, and source position remains optimum (≥1000 lux) for controlling myopia progression. Illuminance level was recorded for 6 outdoor and 5 indoor locations using factory calibrated digital lux meter and under different measurement conditions. Outdoor locations included "open playground," "between two buildings," "between three buildings," "under a porch facing east," "under a big tree," and "under a porch facing west." Similarly, indoor locations included "rooms with multiple large windows," "rooms with a combination of light sources," "room with single artificial light," "room with multiple artificial lights," and "canopy covering the buildings." The overall median illumination level across 6 outdoor locations and 5 indoor locations were 1900 lux (803-4300 lux) and 227 lux (82-556 lux) respectively. Indoor locations showed an overall low median illuminance level (<1000 lux) irrespective of the locations and source positions. However, the illuminance level >1000 lux was recorded for "Room with multiple large windows" for specific points of time (10:00-11:00 and 13:00-14:00) in both sunny and foggy weather. The highest illumination level was recorded only in the "open playground" irrespective of various conditions such as time of the day, weather of the day, relative source position, and sun protection. The ambient illumination level was optimum (≥1000 lux) for antimyopia strategy in winter for maximum outdoor locations. However, children should be motivated to spend their outdoor time during the afternoon (13:00-14:00 h) so that light intensities reaching the eye should be optimum in winter.

8. Clinical Features and Outcomes of Cytomegalovirus Retinitis in Immunosuppressed Non-HIV Patients.
PMID:日期:2024-12-02To describe the nature and response of cytomegalovirus (CMV) retinitis in human immunodeficiency virus (HIV)-negative patients with hematological malignancies and other immunosuppressive causes. This is retrospective case series of CMV retinitis patients with known immunocompromised status and negative HIV results. Patients' data were reviewed for demographics, causes of the immunosuppressed status, concomitant systemic CMV infection, and its management. Ophthalmic findings included visual acuity (VA), anterior and posterior segments findings, CMV retinitis patterns and extensions, medications, number of intravitreal injections, fundus photographs, and CMV retinitis complications. During a study period of 2 years, 17 eyes of 9 patients were diagnosed with CMV retinitis with detected CMV in blood tests. Indolent granular retinitis pattern was found in 4 eyes (23.5%), and the fulminant necrotizing pattern in another 4 eyes (23.5%). In 1 eye (5.9%), frosted branch angiitis was observed. A mixed pattern between granular and necrotizing retinitis was seen in 4 eye (23.5%). The majority (n 11, 64.7%) of the affected eyes had an extensive retinal involvement (zone 1-3). Only two eyes had no macular involvement (11.8%). A large percentage of the included patients had controlled disease course with stable vision. Out of the studied 17 eyes, deterioration in terms of VA was seen in five eyes. In two patients, the disease course was complicated by vitreous hemorrhage. In the majority of the patients with HIV-negative tests who received intravitreal and/or systemic anti-CMV medications, the clinical course of CMV retinitis was controlled with final stable vision.

9. Evaluation of OCTA-based Parameters in Full-thickness Macular Holes: A Prospective, Comparative, Interventional Study.
PMID:日期:2024-12-02This study aims to correlate optical coherence tomography angiography (OCTA)-based retinal microvasculature changes in cases of full-thickness macular hole (FTMH) before and after vitreoretinal surgery and its relation to patient's visual recovery. Data of 31 eyes with FTMH were evaluated preoperatively and post-operatively at 6, 12, and 24 weeks for OCTA parameters and compared. 93.55% eyes (29 eyes) showed improvement in best-corrected visual acuity at 24 weeks. The mean foveal avascular zone (FAZ) significantly reduced from 0.41 ± 0.13 mm (preoperatively) to 0.25 ± 0.01 mm (postoperatively at 24 weeks). Mean preoperative vessel density (VD) in the superficial vascular plexus (SVP) progressively improved to 24.2% ± 2.2%, 25.2% ± 2.1% and 25.8% ± 2.3% at 6, 12, and 24 weeks respectively from 24.4% ± 2.1% preoperatively ( = 0.0, = 5.1). The mean VD of foveal region in the SVP significantly improved ( < 0.0, = 13.9) while that of the parafoveal region did not improve at 24 weeks ( = 0.3, = 1.2) when compared with its preoperative status. The mean preoperative VD in the deep vascular plexus (DVP) was 20.2% ± 2.6%. It significantly improved at 6, 12, and 24 weeks (20.3% ± 2.4%, 21.8% ± 2.3% and 22.1% ± 2.2%, respectively; = 0.0, = 6.9). The mean VD of foveal region and parafoveal region in the DVP showed significant improvement when compared with its preoperative status ( < 0.0, = 39.3, < 0.0, = 13.7). This study showed reduction in mean FAZ area and improvement in mean VD at SVP and DVP in the macula postoperatively. Routine perioperative OCTA-based documentation of macular vascularity in FTMH may throw a light in cases with anatomico-functional postoperative disparities in future.

10. Conjunctival Lymphangiectasia is Likely Lymphatic-venous Lesions: A Clinicopathologic and Immunohistochemical Study.
PMID:日期:2024-12-02To report the clinical presentation, histopathological and immunohistological features of conjunctival lymphatic-venous lesions. This was a retrospective review of 15 patients with symptomatic conjunctival lymphatic-venous lesions. The clinical features and histopathologic features of the excised tissues were reviewed. Immunohistochemical staining with antibodies against CD34 to label vascular endothelium and D2-40 to label lymphatic endothelium was performed. All patients had unilateral conjunctival involvement. The mean age was 48.9 ± 18.9 years, with more women affected (67%). No patient had impaired visual acuity secondary to the lesion. The location of the lesion was temporal in 67% of patients. The presenting symptoms included conjunctival swelling, discomfort and/or foreign-body sensation, and tearing. All lesions were excised, and none recurred. All excised lesions showed dilated channels that were lined by a flattened endothelium staining positive with CD34, surrounded by edematous lamina propria. Larger ectatic lymphatic channels demonstrated scattered D2-40 staining in the endothelial cell lining and patchy CD34 staining within the endothelial cell cytoplasm. D2-40 and CD-34 immunoreactivity did not overlap in the same cells. The clinical features and outcomes of the lesions in this large cohort were similar to those reported in the literature. However, the mixed immunoreactivity of the endothelial cells lining these ectatic lymphatic channels in the conjunctiva suggests that these channels are lymphatic-venous lesions. We suggest that these channels be termed conjunctival lymphaticovenous malformation rather than lymphangiectasia, which suggests ectasia of existing lymphatics. Future studies are needed to understand these lesions and their histopathologic origins.
