Purpose. To evaluate the clinical and diagnostic characteristics of patients with newly diagnosed diabetic macular edema (DME) in Turkey in a real-life setting. Methods. A total of 945 consecutive patients (mean (SD) age: 61.3 (9.9) years, 55.2% male) with newly diagnosed DME were included. Data on patient demographics, comorbidities, ocular history, ophthalmic examination findings including type of DME, central macular thickness (CMT) via time domain (TD) and spectral domain (SD) optical coherence tomography (OCT), and planned treatments were recorded. Results. OCT (98.8%) and fundoscopy (92.9%) were the two most common diagnostic methods. Diffuse and focal DMEs were detected in 39.2% and 36.9% of cases, respectively. Laser photocoagulation (32.1%) and antivascular endothelial growth factors (anti-VEGF; 31.8%) were the most commonly planned treatments. The median CMT in the right eye was significantly greater in untreated than in treated patients [376.5 μm (range: 160–840) versus 342 μm (range: 146–999) (p=0.002)] and in the left eye [370 μm (range: 201–780) versus 329 μm (range: 148–999) (p<0.001)]. Conclusions. This study is the first large-scale real-life registry of DME patients in Turkey. SD-OCT and fundoscopy were the most common diagnostic methods. Laser photocoagulation and anti-VEGF therapy were the most common treatments.

Objectives of the Study. Summary of observational studies concerning the pharmacological management of diabetic macular edema (DME). Methods. A literature review was conducted using the PubMed database on 1 February 2018 to identify studies evaluating the efficacy of anti-VEGF and dexamethasone (DEX) implants for DME. Studies with more than 10 patients and follow-up of more than 6 months were selected. Analyses were carried out on the overall population and on subgroups defined according to baseline visual acuity (BVA) and the patients’ naïve or non-naïve status. Results. Thirty-two studies evaluating the efficacy of anti-VEGF and 31 studies evaluating the efficacy of DEX-implants were retained, concerning 6,842 and 1,703 eyes, respectively. A mean gain of +4.7 letters for a mean of 5.8 injections (mean follow-up: 15.6 months) and +9.6 letters for a mean of 1.6 injections (10.3 months) was found in the anti-VEGF and DEX-implant studies, respectively. Final VA appears to be similar for both treatment (62 letters for anti-VEGF, 61.2 letters for DEX-implant), and BVA appears lower for DEX-implant, which may partially explain the greater visual gain. The DEX-implant studies show greater gains in VA compared to the anti-VEGF studies, especially for higher BVA. Indeed, mean gains for the subgroups of patients with BVA<50 letters, 50<BVA<60 letters, and BVA>60 letters are +4.3, +5.8, and +3.1 letters, respectively, in the anti-VEGF studies and +10.5, +9.3, and +8.8 letters, respectively, in the DEX-implant studies. Regarding the patient’s initial status, only naïve status appears to confer the best functional response in DEX-implant studies. Conclusion. Observational studies investigating DEX-implant report clinically similar final VA when compared to anti-VEGF, but superior visual gains in real-life practice. This latter difference could be due to the better BVA, but also to the fact that less injections were administered in the anti-VEGF observational studies than in the interventional studies.

Patients With Diabetes

Anti-VEGF treatment of diabetic macular edema (DME) complicating diabetic retinopathy (DR) has greatly improved structural and visual outcomes for patients with diabetes mellitus. However, up to 50% of patients are either nonresponsive or refractory to anti-VEGF treatment (no improvement in BCVA or central macular thickness (CMT)). It is believed that factors such as mitochondrial structural and functional damage, due to oxidative stress, are partially responsible for this lack of improvement. Flavoprotein fluorescence (FPF) has been shown to be a sensitive marker of mitochondrial function and has been found to correlate with the degree of diabetic retinopathy. FPF may also provide additional information regarding therapeutic response of patients receiving anti-VEGF treatment for DME. Eight patients with DR and DME with clinically significant DME (CSDME) who underwent anti-VEGF (bevacizumab) treatment were imaged before injection and at follow-up visit using FPF in addition to standard color fundus photography and OCT CMT. A strong correlation r=0.98 (p=0.000015) between the FPF decrease and the BCVA improvement was observed; BCVA improved as FPF values decreased. Notably, in the same patients, the correlation between OCT CMT decrease and BCVA improvement (r=0.688) was not found to be significant (p=0.13). These findings suggest that FPF can detect improvement in metabolic function preceding structural improvement and even with small changes in edema. Additionally, FPF may be supplementary to current diagnostic methods for earlier detection of therapeutic response to anti-VEGF treatment in patients with DME.

Retinal Photocoagulation

Vascular endothelial growth factor (anti-VEGF) inhibitors in action have demonstrated efficacy and safety in the treatment of diabetic macular edema (DME), and have changed both the goal and prospects for treatment of this disease. Consequently, the role of focal laser retinal photocoagulation in the treatment of DME has been actively debated. However, technical advances in new laser systems, treatment protocols for anti-VEGF drug research, and the functional impact of modern focal photocoagulation are necessary to assess the role of laser coagulation in the treatment of DME. A wide range of clinical studies of laser therapy was necessary as an additional treatment for 20 to 50 % of patients receiving monotherapy with anti-VEGF drugs in patients with diabetic macular edema. In addition, a lower frequency of repeated treatment and a more stable reduction in retinal thickness have been demonstrated in other studies. However, the lack of information about the laser systems used, their technical characteristics, and application protocols often make it difficult to compare directly the results of anti-VEGF tests. Therefore, the aim of our work was to analyze the currently available data related to the potential role of focal laser photocoagulation in the treatment of DME, including a detailed review of the most commonly used laser systems. The results obtained with sub-threshold diode micro-pulse laser photocoagulation may be a valuable option as an adjunct therapy to treatment with angiogenesis inhibitors. Current evidence suggests that focal laser therapy should still exist as an adjunct therapy for many patients.
