Objective: To report a case of recurrent vitreous hemorrhage from an optic nerve retinal arterial macroaneurysm (ONRAM) successfully treated with intraoperative endolaser. Patient and Methods: A 92-year-old woman on oral aspirin and warfarin anticoagulation for atrial fibrillation developed three episodes of dense vitreous hemorrhage from an ONRAM. Due to failure of the vitreous hemorrhage to clear spontaneously, a total of three pars plana vitrectomy (PPV) procedures were performed along with a 1.25-mg intravitreal bevacizumab injection after the third episode of hemorrhage. During the third PPV procedure, a 25-gauge 532-nm green diode laser endoprobe was used to deliver low-power (100 mW) and long-duration (500 ms) laser spots directly on the ONRAM to induce intraoperative shrinkage of the ONRAM. Results: After the endolaser treatment, the macroaneurysm showed involution due to fibrosis without any adverse effects on retinal circulation or visual field defect. No recurrence of vitreous hemorrhage was noted after 2 years of follow-up. Conclusion: Oral anticoagulant use may have been responsible for the atypical clinical course in our patient. Laser photocoagulation, including intraoperative endolaser photocoagulation, may be considered in selected cases of symptomatic ONRAMs.

Purpose To evaluate the recurrence of vitreous hemorrhage (VH) in patients treated with intravitreal bevacizumab (IVB) injection (2.5 mg/0.1 mL) intraoperatively at the end of vitrectomy for treatment of diabetic nonclearing VH. Methods A prospective pilot study of 30 eyes of 28 consecutive diabetic patients who underwent pars plana vitrectomy and IVB injection intraoperatively at the end of vitrectomy was performed. The amount of VH was graded with slit lamp biomicroscopy by three masked retinal specialists from grade 0 to grade 3. Main outcome measures were rate of recurrence of the VH, improvement in visual acuity, incidence of cataract formation, and postoperative complications through a follow-up of 6 months. Results The percentage of severe recurrent VH with no fundus details (grade 3) was 7%, 13%, 27%, and 30%, respectively, at 7 days and 1-, 3-, and 6-month follow-up. At 6-month follow-up, the best-corrected visual acuity improved from 1.00 to 0.4 logMAR (p=0.01) in 21 out of 30 eyes (70%). Nine out 20 (40%) phakic patients developed cataract during the follow-up period, and 7 (31%) of them underwent cataract surgery. Conclusions The study suggests that intravitreal bevacizumab injection cannot prevent rebleeding in eyes undergoing pars plana vitrectomy for treatment of diabetic vitreous hemorrhage.

Purpose: To report outcomes of intravitreal bevacizumab therapy for proliferative sickle retinopathy (PSR). Methods: A retrospective, interventional case series. Five eyes of 5 patients with PSR were managed with intravitreal bevacizumab therapy over a 13-year period at a single institution. Results: Four patients had sickle cell-hemoglobin SC disease and 1 had sickle cell-beta thalassemia disease. Four of the patients treated with intravitreal bevacizumab injection were treated for recurrent vitreous hemorrhage and 1 was treated for new peripheral sea fan neovascularization. In those patients treated for vitreous hemorrhage, there was improvement in visual acuity as early as 2 weeks after treatment. Only 2 of the patients had documented recurrent vitreous hemorrhage during the period of follow-up after the initial injection. In 1 patient, the vitreous hemorrhage did not recur until 13 months after the injection. All patients showed an anatomic response to intravitreal bevacizumab therapy with partial regression of the peripheral sea fan neovascularization. All patients tolerated the injections without any complications. Conclusions: Intravitreal bevacizumab injections appear to be well tolerated and may be an effective treatment of PSR. Regression of peripheral sea fan neovascularization and decreased duration of vitreous hemorrhage may be observed. Large-scale randomized controlled trials are needed to further clarify the role of bevacizumab in PSR.

MicroRNAs (miRNAs) can provide insight into the pathophysiological states of ocular tissues such as proliferative diabetic retinopathy (PDR). In this study, differences in miRNA expression in vitreous from PDR patients with and without incidence of recurrent vitreous hemorrhage (RVH) after the initial pars-plana vitrectomy (PPV) were analyzed, with the aim of identifying biomarkers for RVH. Fifty-four consented vitreous samples were analyzed from patients undergoing PPV for PDR, of which eighteen samples underwent a second surgery due to RVH. Ten of the sixty-six expressed miRNAs (miRNAs-19a, -20a, -22, -27a, -29a, -93, -126, -128, -130a, and -150) displayed divergences between the PDR vitreous groups and to the control. A significant increase in the miRNA-19a and -27a expression was determined in PDR patients undergoing PPV as compared to the controls. miRNA-20a and -93 were significantly upregulated in primary PPV vitreous samples of patients afflicted with RVH. Moreover, this observed upregulation was not significant between the non-RVH and control group, thus emphasizing the association with RVH incidence. miRNA-19a and -27a were detected as putative vitreous biomarkers for PDR, and elevated levels of miRNA-20a and -93 in vitreous with RVH suggest their biomarker potential for major PDR complications such as recurrent hemorrhage incidence.

Purpose: To investigate the effects of intravitreal bevacizumab injection combined with laser photocoagulation in patients with retinal microaneurysms.Methods: We retrospectively reviewed the medical records of 21 eyes of 21 patients who underwent intravitreal bevacizumab injection and/or laser photocoagulation to treat retinal macroaneurysms. Eleven eyes received the combination therapy (CT) and 10 eyes monotherapy (MT) (either bevacizumab injection or laser photocoagulation). Changes in visual acuity, central macular thickness, macroaneurysm size and location, blood pressure, and the lipid level were compared between the two groups.Results: The mean patient age was 74.0 ± 10.5 years and the mean study period 7.0 ± 5.3 months. The mean macroaneurysm diameter of the CT group was 480.00 ± 292.30 μm and that of the MT group 328.75 ± 87.09 μm. The diameter was significantly larger in the CT group (p = 0.002). The initial visual acuities were 0.91 ± 0.66 and 0.88 ± 0.83 in the CT and MT groups, respectively. At the 4-month follow-up, the visual acuities were 0.33 ± 0.26 and 0.17 ± 0.29 in the CT and MT groups, respectively, and had significantly improved only in the CT group (p = 0.042). The initial central macular thicknesses were 441.82 ± 226.81 and 541.63 ± 401.97 μm in the CT and MT groups, respectively. At the 4-month follow-up, the figures were 293.60 ± 46.10 and 269.00 ± 48.34 μm in the CT and MT groups, respectively, and had significantly decreased only in the CT group (p = 0.043). Compared to the initial findings, the proportion of patients whose final visual acuities improved by more than two lines were 73% and 40%, respectively, thus significantly higher in the CT group (p < 0.001).Conclusions: Combined intravitreal bevacizumab injection and laser photocoagulation treatment of retinal macroaneurysms improve visual acuity and decrease macular thickness.

Tube shunt complications of the retina and vitreous can threaten vision. It is important to understand how to recognize, prevent, and manage these complications. While many retrospective studies regarding retinal complications of tube shunts are in the literature, there are now 2 major prospective studies that can be looked to for the incidence of retinal complications. In the Tube Versus Trabeculectomy (TVT) Study, at 3 years of follow-up, 4 eyes out of 107 total eyes (4%) with tube shunts had required pars plana vitrectomies due to a retinal complication (e.g., vitreous occlusion of the tube, retinal detachment, choroidal detachment). Drainage of a choroidal effusion was performed in 2 patients. Early postoperative retinal complications (onset at 1 month or less after tube shunt implantation) included choroidal effusion (15 eyes; 14%), suprachoroidal hemorrhage (2 eyes; 2%), and vitreous hemorrhage (1 eye; 1%). Late postoperative retinal complications (onset more than 1 month after tube shunt implantation) included choroidal effusion (2 eyes; 2%) and retinal detachment (1 eye; 1%). In the Ahmed Baerveldt Comparison (ABC) Study, at one year of follow-up, one eye of 276 total eyes (0.4%) required a pars plana vitrectomy to clear a postoperative hemorrhage and one eye (0.4%) required reoperation for drainage of a suprachoroidal hemorrhage. Early postoperative retinal complications (3 months of less after implantation of the tube shunt) reported included choroidal effusion (34 eyes; 12%), suprachoroidal hemorrhage (2 eyes; 1%), endophthalmitis (1 eye; 0.4%), and vitreous hemorrhage (5 eyes; 2%). Late retinal postoperative complications (more than 3 months after tube shunt implantation) included choroidal effusion (3 eyes; 1%), endophthalmitis (2 eyes; 1%), vitreous hemorrhage (3 eyes; 1%), and retinal detachment (2 eyes; 1%). Both of these studies indicate a similar incidence of retinal complications after tube shunt implantation. Tube shunt surgery is performed in cases of uncontrolled glaucoma where medications are inadequate. A pars plana tube is most often indicated for anatomic reasons, such as a small eye, or an eye that already has coexisting corneal disease.
