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.


Diabetes mellitus leads to two major complications, diabetic retinopathy (DRP) and diabetic macular edema (DME), resulting in loss of vision. Diabetes mellitus is the most common cause of loss of vision when all age groups are taken into account. However, this complication can be prevented or delayed with various treatments, especially strict blood glucose regulation. Laser, anti-VEGF, and corticosteroids are used in the treatment of DME. Laser therapy is applied as a focal / grid or pan-retinal photocoagulation. Nowadays, different lasers are presented to use in the treatment in DRP and DME. Each has different advantages and disadvantages. This article discusses the characteristics of lasers used in the treatment of DRP and DME.

Objective: To explore the clinical efficacy of intravitreal injection of conbercept in combination with retinal laser photocoagulation in the treatment of diabetic macular edema. Methods: Ninety patients with diabetic macular edema were selected and grouped into an observation group and a control group using random number table, 45 patients (45 eyes) each group. The control group was given retinal laser photocoagulation, while the observation group was given intravitreal injection of Conbercept on the basis of panretinal photocoagulation. The Best Corrected Visual Acuity (BCVA), thickness of retinal nerve fibre layer (RNFL) and macular thickness were measured through relevant examinations before and after treatment. The intraocular pressures of patients in the two groups were evaluated, and moreover the complications were recorded. Results: The RNFL thickness and macular thickness of the two groups had no statistically significant differences before treatment (P>0.05) and decreased significantly after treatment; the decrease amplitude of the observation group was significantly larger than that of the control group (P<0.05). The BCVA of both groups significantly increased in the 1st, 2nd and 4th week after treatment (P<0.05); the increase amplitude of BCVA of the observation group was more significant than that of the control group at different time points after treatment (P<0.05). The intraocular pressure of the observation group was not significantly different with that of the control group in the 1st, 2nd and 4th week after treatment (P>0.05). There were no severe eye complications and systemic adverse reactions in both groups in the process of follow up. Conclusion: Intravitreal injection of conbercept in combination with retinal laser photocoagulation performs better in improving the BCVA and central macular thickness of patients with diabetic macular edema compared to retinal laser photocoagulation and has high safety. doi: https://doi.org/10.12669/pjms.35.6.512 How to cite this:Meng W, Li R, Xie X.

Diabetic macular edema and diabetic intravitreal hemorrhage are frequent complications of diabetes. In selected cases of diabetic macular edema which is primarily treated with intravitreal injections, surgery may be performed. In this review, the role of surgery in diabetic macular edema will be discussed in light of the current literature. Moreover, changes in the timing of surgery in diabetic intravitreal hemorrhage since DRVS and risk factors and the efficacy of preventive measures for post vitrectomy intravitreal hemorrhage will be discussed.
