Interleaved Optical Coherence Tomography: Clinical and Laboratory Biomarkers in Patients with Diabetic Macular Edema. J Pers Med 2022; 12:jpm12050765. [PMID: 35629188 PMCID: PMC9147367 DOI: 10.3390/jpm12050765] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 05/03/2022] [Accepted: 05/06/2022] [Indexed: 02/05/2023] Open
Abstract
(1) Background: The global burden of diabetes mellitus (DM) has been estimated to reach 600 million patients worldwide by 2040. Approximately 200 million people will develop diabetic retinopathy within this time frame. Diabetic macular edema (DME) is a severe, vision-threatening complication that can develop at any stage of diabetic retinopathy, and it represents the main cause of vision loss in patients with DM. Its harmful consequences on visual function could be prevented with timely recognition and treatment. (2) Methods: This study assessed the clinical (demographic characteristics, diabetic evolution, and systemic vascular complications); laboratory (glycated hemoglobin, metabolic parameters, capillary oxygen saturation, and renal function); ophthalmologic exam; and spectral-domain optical coherence tomography (SD–OCT) (macular volume, central macular thickness, maximal central thickness, minimal central thickness, foveal thickness, superior inner, inferior inner, nasal inner, temporal inner, inferior outer, superior outer, nasal outer, and temporal outer thicknesses, disruption of the ellipsoid zone, and disruption of the inner retinal layers (DRIL) parameters in three groups of individuals: healthy controls (HC), patients with DME and type 1 DM (T1DM—group A), and patients with DME and type 2 DM (T2DM—group B) to identify novel correlations between them that would open a path to new pathogenetic hypotheses and, implicitly, to the identification of new therapeutic methods, as part of a tailored treatment within the concept of precision medicine. (3) Results: The duration of DM was significantly longer in group A as compared with group B, as were the prevalence of smoking and systemic vascular complications. Capillary oxygen saturation and estimated glomerular filtration rates were significantly lower, and serum creatinine levels were significantly higher in group A as compared to group B. Regarding the OCT findings, DME had a predominantly eccentric pattern, and the right eye was more severely affected in both groups of patients. Significantly higher values were obtained in group B as compared to group A for the following OCT biomarkers: macular volume, central macular thickness, maximal central thickness, minimal central thickness, foveal thickness, superior inner, inferior inner, nasal inner, inferior outer and nasal outer thickness. The disruption of the ellipsoid zone was significantly more prevalent within group A, whereas the overall disruption of the retinal inner layers (DRIL) was identified significantly more frequently in group B. (4) Conclusions: Whereas systemic and laboratory biomarkers were more severely affected in patients with DME and T1DM, the OCT quantitative biomarkers revealed significantly higher values in patients with DME and T2DM.

Abstract
PURPOSE To evaluate whether outcome of bevacizumab treatment in the first treated eye can guide the selection of compound for the second treated eye in patients with bilateral diabetic macular edema. METHODS Demographic, clinical, and optical coherence tomography data were retrospectively collected from consecutive patients who underwent bevacizumab therapy for bilateral diabetic macular edema. Change in central subfield thickness and visual acuity were evaluated and compared between the first treated eye and second treated eye. RESULTS A total of 66 eyes of 33 patients were included in the study. The mean ± SD follow-up time was 13 ± 5 months. The mean ± SD central subfield thickness at baseline was 464 ± 30 μm in the first treated eye and 461 ± 29 μm in the second treated eye (p = 0.91). Final central subfield thickness was reduced to 392 ± 27 μm in the first treated eye (p = 0.01 compared with baseline) and 416 ± 25 μm in the second treated eye (p = 0.03 compared with baseline). Using ≥5% or ≥10% reduction of central subfield thickness as diagnostic criteria to predict similar magnitude of thickness reduction in the first treated eye yielded a positive and negative predictive value ranging from 46% to 81%, and sensitivity and specificity ranging from 54% to 84%. Regression models did not show correlation between central subfield thickness reduction in first treated eye and the second treated eye at the end of follow-up. CONCLUSIONS Bevacizumab therapy reduced macular thickness in both eyes in bilateral diabetic macular edema. Treatment outcome of the first treated eye could not predict the outcome of the second treated eye. Particularly, failure to reduce central subfield thickness in the first treated eye does not preclude a favorable response to bevacizumab therapy in the second eye.

Abstract
PURPOSE To evaluate the anatomical correlation between fellow eyes for bilateral second-line anti-VEGF treatment in eyes with bilateral diabetic macular edema (DME) with incomplete response to first-line bevacizumab therapy. METHODS Seventy-four eyes (n = 37 patients) with bilateral-DME having incomplete response to first-line bevacizumab therapy that were switched for bilateral treatment with ranibizumab were retrospectively evaluated. Data collected included demographics, visual acuity and macular thickness. We evaluate the correlation for the response of both eyes in terms of macular thickness and visual acuity. RESULTS The mean±SD age was 76 ± 8 years. The mean±SD number of bevacizumab injections prior the switch was 11.03 ± 5.1 in the first eye (FE) and 10.9 ± 5.2 in the second eye (SE). The central subfield thickness (CST) reduced from 472 ± 171 microns at baseline to 418 ± 161 after the last bevacizumab injection and 365 ± 74 after 3 ranibizumab injections in the FE (p = .016, p = .004, respectively), and from 463 ± 145 microns to 446 ± 123, and 421 ± 103 in the SE (p = .112, p = .001, respectively). There was strong positive correlation between the eyes for the CST reduction under bevacizumab and ranibizumab treatments in each visit. BCVA± SD at baseline was 0.41 ± 0.30 LogMAR in the FE, and 0.42 ± 0.29 in the SE (p = .44). After 3 injections of bevacizumab, the BCVA was 0.37 ± 0.26 and 0.42 ± 0.23 in FE and SE respectively (p = .013, p = .132, respectively). CONCLUSIONS This study demonstrated a strong anatomical correlation responses between the eyes in patients with bilateral DME for both first-line bevacizumab therapy and second-line ranibizumab therapy. Response to second-line therapy was favorable and correlated among eyes regardless they were from the same or different individuals.

García Layana A, Adán A, Ascaso FJ, Cabrera F, Donate J, Escobar Barranco JJ, Peralta G, Reyes García R, Rodríguez Maqueda M, Ruiz-Moreno JM, Vinagre I. Use of intravitreal dexamethasone implants in the treatment of diabetic macular edema: Expert recommendations using a Delphi approach. Eur J Ophthalmol 2019; 30:1042-1052. [DOI: 10.1177/1120672119861623] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/22/2022]
Abstract
Objective: The aim of this study is to develop guidance on the use of intravitreal dexamethasone implants in the treatment of diabetic macular edema. Method: The study was performed using the modified Delphi method to obtain a consensus among a panel of experts on management of patients with diabetic macular edema and use of intravitreal dexamethasone implants in clinical practice. Thirty-seven panel members, experts on retina, from different Spanish centers were invited to participate. Individual and anonymous opinions were asked by answering a 76-item questionnaire across 11 topic areas (two rounds were done). Level of agreement was assessed using a Likert-type scale of 9 points. Results: Agreement on “consensus” was reached during the first round in 63 items. The 13 remaining items underwent a second round of voting. After the second round, agreement on “consensus” was reached on five items. Finally, eight items remained without consensus. Conclusion: Intravitreal dexamethasone implants are useful in the treatment of patients with diabetic macular edema with different profiles, for example, pseudophakic, poor-adherents, vitrectomized, candidates for cataract surgery, patients with high inflammatory component, and with a history of cardiovascular events. The use of intravitreal dexamethasone reduces the number of visits and facilitates compliance. Experts thought that the switch from anti-vascular endothelial growth factor therapy to intravitreal dexamethasone implants should be done preferably after three injections. Also, pro re nata treatment provides better results in diabetic macular edema patients as it helps to prevent undertreatment. Finally, experts concluded that clinical guidelines and treatment protocols for diabetic macular edema need to be updated.
