Abstract Purpose: To evaluate the effect of three monthly intravitreal injections of a Rho-associated protein kinase (ROCK) inhibitor (Fasudil, Asahi Kasei Pharma Corporation, Tokyo, Japan) on refractory diabetic macular edema (DME).Study design: Prospective – clinical Methods: This interventional case series included 10 eyes of 10 patients with DME unresponsive to at least six previous intravitreal bevacizumab (IVB) injections. Eligible eyes underwent intravitreal injection of 0.025 mg/0.05 ml Fasudil. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were evaluated as functional and anatomical response indicators, respectively. Results: Mean age was 60.1±5.1 (range, 53-68) years. Five cases responded to treatment; two with both anatomical and functional response (reduction of CMT from 521 to 395 and from 390 to 301microns and improvement of BCVA from 0.3 to 0.1 LogMAR and 0.6 to 0.4 LogMAR, respectively) and three with only functional improvement (0.7 to 0.4; 0.7 to 0.4; and 0.3 to 0.1 LogMAR). Of note, cases with no significant CMT change had morphologic improvement of retinal microstructure to some extent. No adverse event was observed during the study period.Conclusion: Monotherapy with intravitreal injection of ROCK inhibitors seems to have moderate visual benefits in eyes with DME refractory to IVB. Such effects may be functionally significant without obvious anatomical improvement.

Best Corrected Visual Acuity

Diabetic Macular Edema (DME) adalah penyebab utama kebutaan pada populasi diabetes. Salah satu patogenesis pada DME adalah karena peningkatan ekspresi VEGF. Bevacizumab adalah anti-VEGF yang dapat meningkatkan Best Corrected Visual Acuity (BCVA) dan mengurangi Central Macular Thickness (CMT) pada pasien DME. Tujuan: Mengetahui persentase jenis kelamin, usia, durasi DM tipe II, BCVA dan CMT sebelum dan setelah injeksi pada bulan pertama dan bulan ketiga pada pasien DME serta menganalisis pengaruh intravitreal bevacizumab anti-VEGF terhadap BCVA dan CMT pada DME di Rumah Sakit M Djamil Padang. Metode: Penelitian ini adalah studi retrospektif analitik berdasarkan rekam medis dari 16 pasien DME yang telah injeksi bevacizumab intravitreal pada tahun 2017. Data dianalisis secara statistik menggunakan uji one way Anova dengan p < 0,05 dianggap signifikan. Hasil: Pasien terdiri dari 11 wanita (68,8%) dan 5 pria (31,2%). Jumlah usia pasien terbanyak antara 51-55 tahun (43,8%) dan durasi terlama yang diketahui DM tipe II adalah 5-10 tahun (50,0%). Rata-rata BCVA (logMAR) sebelum injeksi intravitreal bevacizumab adalah 0,95, bulan pertama setelah injeksi adalah 0,68, dan bulan ketiga setelah injeksi adalah 0,55. CMT rata-rata sebelum injeksi bevacizumab intravitreal adalah 427,62, bulan pertama setelah injeksi 359,59, dan bulan ketiga setelah injeksi 318,12. Simpulan: Terdapat pengaruh bevacizumab anti-VEGF intravitreal terhadap BCVA dan CMT di DME di Rumah Sakit M Djamil Padang.

Purpose: To evaluate the change in visual acuity in relation to decrease in central macular thickness,after a single dose of intravitreal Bevacizumab injection.Study Design: Quasi experimental study.Place and Duration of Study: Punjab Rangers Teaching Hospital, Lahore, from January 2019 to June 2019.Material and Methods: 70 eyes with diabetic macular edema were included in the study. Patients having high refractive errors (spherical equivalent of > ± 7.5D) and visual acuity worse than +1.2 or better than +0.2 on log MAR were excluded. Central macular edema was measured in μm on OCT and visual acuity was documentedusing Log MAR chart. These values were documented before and at 01 month after injection with intravitrealBevacizumab. Wilcoxon Signed rank test was used to evaluate the difference in VA beforeand after the anti-VEGF injection. Difference in visual acuity and macular edema (central) was observed,analyzed and represented in p value. P value was considered statistically significant if it was less than 0.01%.Results: Mean age of patients was 52.61 ± 1.3. Vision improved from 0.90 ± 0.02 to 0.84 ± 0.02 on log MARchart. The change was statistically significant with p value < 0.001. Central macular thickness reduced from 328 ±14 to 283 ± 10.6 μm on OCT after intravitreal anti-VEGF, with significant p value < 0.001.Conclusion: A 45 μm reduction in central macular thickness was associated with 0.1 Log MAR unit improvementin visual acuity after intravitreal Bevacizumab in diabetic macular edema.

Purpose: To compare the effectiveness of intravitreal ranibizumab (IVR) for diabetic macular edema (DME) between eyes with and without previous vitrectomy. Procedures: We prospectively assessed the best-corrected visual acuity (BCVA) and central macular thickness (CMT) after IVR for 6 months. Results: There were no significant differences in the baseline BCVA and CMT between both groups. In the nonvitrectomized group (n = 15), the mean changes of BCVA and CMT from baseline to month 6 were significant (p < 0.01). In the vitrectomized group (n = 10), the improvement appeared to be slower, and the mean BCVA improvement was not significant (p = 0.5), although the mean CMT decrease was significant (p < 0.05). There were no significant differences in the mean changes of BCVA and CMT between both groups at 6 months. Conclusions: The difference in the effectiveness of IVR between both groups was not significant. IVR can be a treatment option even for vitrectomized DME eyes.

Purpose: To report the results of intravitreal injection of a bevacizumab biosimilar called Stivant®. Methods: This prospective interventional case series was conducted on eyes with neovascular age-related macular degeneration (nAMD), retinal vein occlusion (RVO), and diabetic macular edema (DME). Stivant® was injected in three consecutive months and changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) were measured at baseline and monthly up to one month after the third injection. Results: Three hundred and eighty-five eyes with DME (234 eyes, 61%), nAMD (87 eyes, 22%), and macular edema secondary to RVO (64 eyes, 17%) were enrolled. The mean ± standard deviation age of the patients was 61.7 ± 7.20 years. The mean BCVA and CMT changed from 0.63 ± 0.3 to 0.51 ± 0.3 LogMAR (P = 0.12 ) and from 420.4 ± 47.3μm at baseline to 316.7 ± 50.6 μm (P < 0.001) in the DME group; from 0.79 ± 0.3 to 0.68 ± 0.3 LogMAR (P = 0.19) and from 376.1 ± 31.7 μm to 303 ± 31.3 μm (P = 0.019) in the nAMD group; and from 0.81 ± 0.4 to 0.63 ± 0.4 LogMAR (P = 0.05) and from 424.21 ± 18 μm to 303.4 ± 18.8 μm (P < 0.001) in the RVO group, respectively. Conclusion: Our limited experience showed that the intravitreal injection of Stivant® was well tolerated. Although the results of this case series showed relative improvement in CMT one month after the last injection of Stivant®, BCVA improvement was statistically significant only in the RVO group. This would be essential to design a randomized clinical trial to evaluate the non-inferiority of Stivant® in comparison to bevacizumab.

Purpose: To evaluate the 1-year results of 25-gauge microincision vitrectomy surgery (MIVS25) combined with intraoperative dexamethasone (DEX) implant for persistent diabetic macular edema (DME). Methods: This study enrolled patients who had a history of DME for ≥12 months and underwent MIVS25 and DEX implant injection. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) were assessed postoperatively. Results: Eighteen eyes were included in the analysis. Preoperatively, logMAR BCVA was 0.90 and CRT was 594 µm on average. CRT decreased until the 3-month follow-up visit and tended to increase at 6 months, but stabilized at 12 months with additional treatments in five eyes at 5 months postoperatively. Statistically significant improvement in BCVA was noted 1 month after treatment and at each subsequent follow-up visit (p < 0.001). Conclusion: MIVS25 combined with DEX implant injection might be utilized as an effective and safe alternative treatment for intractable DME.
