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.

Aims: To investigate the changes in vision-related quality of life after a loading dose of three consecutive intravitreal ranibizumab (IVR) injections in patients with unilateral diabetic macular edema (DME). Materials and Methods: Fifty-two eyes of 52 patients who received IVR injections in only one eye with DME were included in our study. The following characteristics of the patients were recorded: gender, education status, marital status, work status, presence of chronic disease. The changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) were evaluated at baseline (before treatment) and 1 month after the third intravitreal injection (after treatment). Patients were administered the Turkish form of the National Eye Institute 25-Item Visual Functions Questionnaire (NEI VFQ-25 TR). The quality of life scores assessed by the NEI VFQ-25 TR, the BCVA, intraocular pressure (IOP), and CMT measurements were compared at baseline (before treatment) and 1 month after the third intravitreal injection (after treatment). Results: We enrolled 52 patients (25 females, 27 males) in our study; mean age was 64.35 ± 9.26 years. After treatment, BCVA improved significantly (p = 0.001), and macular thickness decreased significantly (p < 0.001). All NEI VFQ-25 TR subscale scores were significantly higher after treatment (p < 0.05). However, no significant correlation was found between the change in BCVA and CMT and the change in NEI VFQ-25 TR subscale and composite scores. The increase in near activities scores was significantly higher in males (p = 0.020) and in the retired group (p = 0.022). There were no significant differences in the changes in NEI VFQ-25 TR subscale and composite scores in relation to educational status. Discussion: Significant improvements in BCVA, macular edema, and vision-related quality of life were found in DME patients who received IVR injections with a loading dose, as shown by the NEI VFQ-25 TR. Interestingly, a significant improvement in quality of life was observed even though the patients could see well with the fellow eye. In conclusion, the NEI VFQ-25 TR is a useful scale to evaluate the changes in visual function and psychosocial characteristics of DME patients after treatment.

Purpose. To conduct a comparative analysis of the effectiveness of intravitreal injection of dexamethasone-containing implant and aflibercept in macular edema in patients with diabetes mellitus. Material and methods. The study involved 80 patients (80 eyes) with macular edema. The group 1 included 38 patients (38 eyes) who underwent a single intravitreal injection of dexamethasone-containing biodegradable implant «Ozurdex» in a dose of 0.7 mg according to the standard technique. In the group 2, 42 patients (42 eyes) received 5 loading doses of aflibercept with an interval of one month. All patients underwent monthly spectral optical coherence tomography (OCT) of the macular area, as well as visometry and tonometry during the observation period. Results. One month after intravitreal injection of the studied drugs in both groups, no inflammatory reactions were detected in any case. According to OCT data, cystic edema of the macular area with a tendency to decrease the thickness in the fovea was preserved. After treatment with aflibercept, the average retinal thickness in the macula was 186.4±15.1 µm, and visual acuity averaged 0.48±0.05 in 85.7% of patients. During therapy with intravitreal injection of Ozurdex, an increase in visual acuity was noted in 89.4% of patients. Conclusion. This study found that intravitreal pharmacotherapy with an angiogenesis blocker and a dexamethasone implant in patients with diabetic macular edema are comparable in its effectiveness – 85.7 and 89.4% respectively. If systematic anti-angiogenesis therapy is not possible for a number of reasons, it is advisable to use a prolonged dexamethasone implant. Key words: macular edema, intravitreal pharmacotherapy, angiogenesis inhibitor, implant with dexamethasone.
