PURPOSE: The authors report a case of bilateral simultaneous central retinal vein occlusion caused by Waldenstrom's macroglobulinemia. CASE SUMMARY: A 65-year-old man presented to our department complaining of decreased visual acuity for the duration of about 6 months. On his initial visit, best-corrected visual acuity was 0.02 in the right eye and 0.06 in the left eye. Based on the findings of a funduscopic examination, the patient had bilateral diffuse retinal hemorrhages, dilated tortuous veins, and macular edema. He had experienced recurrent spontaneous epistaxis 6 months previously and had undergone treatments such as intravitreal bevacizumab injection and intravitreal dexamethasone implantation at another hospital. Laboratory tests at that hospital showed anemia and hyperproteinemia, for which he was referred to our hemato-oncology department. Bone marrow biopsy was consistent with Waldenstrom's macroglobulinemia/lymphoplasmacytoid lymphoma, and he was treated with systemic chemotherapy. One year after the systemic chemotherapy, his best-corrected visual acuity was 0.15 in the right eye and 0.6 in the left eye. Funduscopy showed decreased bilateral retinal hemorrhages and macular edema. CONCLUSIONS: When simultaneous bilateral central retinal vein occlusion occurs in a patient with no other underlying disease such as hypertension or diabetes, it might be a sign of serum hyperviscosity, and there should be a very high level of suspicion for presence or progression of systemic disease. If such a disease is properly and timely diagnosed, effective early systemic evaluation and therapy can be administered, and it is important to have initial general treatment as well as ophthalmic treatment.

Bietti crystalline retinal dystrophy is a rare, inherited disorder whose hallmark is the presence of retinal crystal deposits associated with later chorioretinal degeneration. This condition may rarely be complicated by the development of cystoid macular oedema leading to rapid visual decline. Currently, treatment options for this complication of Bietti dystrophy are limited and the visual prognosis is poor. Here, we present a case of cystoid macular oedema associated with Bietti dystrophy that was successfully diagnosed using multimodal imaging techniques including optical coherence tomography and fluorescein angiography. These modalities confirmed the diagnosis of macular oedema and excluded other possible causes of oedema such as choroidal neovascularisation. In this patient, cystoid macular oedema was resolved with oral acetazolamide therapy, a treatment that has not been previously reported in this context. Acetazolamide treatment resulted in oedema resolution and improvement in visual function, and can be considered a therapeutic option for other patients with Bietti dystrophy who develop cystoid macular oedema.

PURPOSE: To compare pain scores of patients during intravitreal 27-gauge bevacizumab and 30-gauge ranibizumab injection procedures. METHODS: Seventy eyes of 70 patients who had not previously undergone intravitreal anti-vascular endothelial growth factor therapy were included in this study. Thirty-five patients received ranibizumab and 35 patients received bevacizumab. The diagnoses of the patients were: 27 age related macular degeneration, 15 diabetic macular edema, 9 diabetic vitreous hemorrhage, 6 central retinal vein occlusion, 11 branch retinal vein occlusion and 2 central serous chorioretinopathy. Bevacizumab (1.25 mg/0.05 mL) was injected into the vitreous cavity using a 27-gauge needle, and ranibizumab (0.5 mg/0.05 mL) was injected with 30-gauge needle. Patients were asked just after the injection to rate their perceived pain during the injection using the visual analogue scale (VAS) of 0 (no pain) to 10 (unbearable/worst pain). The average of these scores was used as the primary outcome. RESULTS: The VAS pain scores in the ranibizumab and bevacizumab groups were 1.06 +/- 0.91 (range, 0 to 3) and 1.94 +/- 1.55 (range, 0 to 7), respectively, a significant difference (p = 0.005). Patients <65 and > or =65 years of age in both the ranibizumab and bevacizumab groups were then compared. For patients <65, there was a significant difference in the average VAS pain scores between groups (p = 0.003). However, for patients > or =65 years, there was not a significant difference in the average VAS pain scores between groups (p = 0.238). Female and male patients in both ranibizumab and bevacizumab groups were also compared. For female patients, there was a significant difference in the average VAS pain scores between groups (p = 0.016), although not for male patients (p = 0.078). CONCLUSIONS: Thirty-gauge intravitreal injection is more comfortable than 27-gauge injection. Injection of bevacizumab with 30-gauge needle syringes may be more tolerable for patients.

INTRODUCTIONAlthough laser photocoagulation is the primary treatment for diabetic macular oedema, treatment of eyes with diffuse macular oedema has been disappointing. Intravitreal injection of steroids is being investigated for the treatment of diabetic macular oedema. Preliminary results indicate that steroid injections do improve macular oedema, but it is not clear if they improve visual acuity.

CLINICAL PICTURE, TREATMENT, AND OUTCOMEIn this report, we describe a patient with a form of diffuse diabetic macular oedema that responded favourably to intravitreal steroid injections, with improvements in both foveal thickness and visual acuity.

CONCLUSIONIntravitreal steroids can be useful for the treatment of diffuse diabetic macular oedema.

We encountered a patient with cystoid macular edema (CME) secondary to paclitaxel use. A 57-year-old man presented with gradual decreased bilateral vision. His chemotherapeutic regimen consisted of bevacizumab, paclitaxel (175 mg/m2 for 5 months), and carboplatin. Optical coherence tomography imaging revealed bilateral CME greater than 500 microm. However, one year later, visual acuity was improved, best-corrected Snellen visual acuity was 40 / 80 in each eye, and CME was spontaneously improved. Our study confirmed that macular edema associated with paclitaxel use shows spontaneous resolution and improvement of visual acuity after a change of chemotherapeutic regimen.

PURPOSE: To compare the efficacy between macular laser grid (MLG) photocoagulation and MLG plus intravitreal triamcinolone acetonide (IVTA; MLG+IVTA) therapy in diabetic macular edema (DME) patients. METHODS: A prospective, randomized, clinical trial was conducted of DME patients. A total of 60 eyes (54 patients) affected by DME were observed for a minimum of 6 months. Thirty eyes of 28 patients who received MLG treatment and 30 eyes of 26 patients who received the combined MLG+IVTA treatment were included in the study. Main outcome measures were BCVA and central macular thickness (CMT) as measured by optical coherence tomography (OCT) at 1, 3, and 6 months after treatment. Additionally, the authors examined retrospectively 20 eyes of 20 patients who were treated with only IVTA and compared with the 2 groups (MLG group and MLG+IVTA group). RESULTS: Baseline BCVA was 0.53+/-0.32 and CMT was 513.9+/-55.1 microm in the MLG group. At 1 and 3 months after treatment, the MLG group showed no significant improvement of BCVA and CMT, although there was significant improvement after 6 months. In the MLG+IVTA group, the baseline BCVA was 0.59+/-0.29 and CMT was 498.2+/-19.8 microm. After treatment, significant improvement of BCVA and CMT was observed at all follow-up time periods. When comparing the MLG group with the MLG+IVTA group, the latter had better results after 1 and 3 months, although at 6 months, there was no significant difference of BCVA and CMT between the 2 groups. Additionally, the IVTA group showed more improvement than the MLG group at 1 and 3 months but showed no significant difference at 6 months. In addition, the IVTA group showed no significant difference with the MLG+IVTA group at all follow-up time periods. CONCLUSIONS: For DME patients, the combined MLG+IVTA treatment had a better therapeutic effect than the MLG treatment for improving BCVA and CMT at the early follow-up time periods. IVTA treatment alone could be an additional alternative therapeutic option to combined therapy.

PURPOSE: To compare the short-term effects of intravitreal triamcinolone acetonide (IVTA) with those of intravitreal bevacizumab (IVB) injection for diabetic macular edema (DME). METHODS: The present retrospective, comparative case study included 58 eyes of 35 consecutive patients (IVTA group, 20 eyes; IVB group, 38 eyes) with DME. IVTA (4 mg) or IVB (1.25 mg) injection was performed under local anesthesia. The effects of injection for DME were evaluated using best-corrected visual acuity (BCVA), central macular thickness (CMT) by optical coherence tomography and intraocular pressure (IOP) by applanation tonometer. Patients underwent eye examinations, including BCVA, CMT, and IOP at pre-injection, 2, 4, and 8 weeks after injection. RESULTS: BCVA (logarithm of the minimum angle of resolution) +/- SD at pre-injection, 2, 4, and 8 weeks after injection was 0.67 +/- 0.40, 0.56 +/- 0.35 (p = 0.033), 0.55 +/- 0.33 (p = 0.041), and 0.43 +/- 0.31 (p = 0.001) in the IVTA group and 0.51 +/- 0.31, 0.42 +/- 0.26 (p = 0.003), 0.43 +/- 0.32 (p = 0.001), and 0.43 +/- 0.27 (p = 0.015) in the IVB group, respectively. CMT (microm) +/- SD at pre-injection, 2, 4, and 8 weeks after injection was 400.4 +/- 94.9, 332.8 +/- 47.4 (p = 0.002), 287.5 +/- 49.1 (p = 0.007), and 282.5 +/- 49.6 (p = 0.043) in the IVTA group and 372.6 +/- 99.5, 323.2 +/- 72.4 (p = 0.077), 360.9 +/- 50.3 (p = 0.668), 368.2 +/- 88.6 (p = 0.830) in the IVB group, respectively. CONCLUSIONS: The effects of IVTA for BCVA were more favorable than were those of IVB and were consistent throughout the eight weeks after injection. IVTA significantly reduced CMT during the eight weeks after injection, while IVB did not.

A 54-year-old female patient who had been undergoing anti-cancer chemotherapy and radiotherapy for seven years after surgery for left breast cancer visited our clinic for visual disturbance in the right eye at nine months after paclitaxel administration. The best-corrected visual acuity was 0.5 in the right eye and 1.0 in the left eye. The patient was diagnosed with maculopathy due to paclitaxel administration based on the finding of cystoid macular edema in the right eye on fundus examination and optical coherence tomography; however, no leakage was detected on fluorescein angiography. Thus, drug replacement was planned. On the other hand, no abnormal finding was observed in the left eye. However, as the anti-cancer effect of paclitaxel is significant, replacing paclitaxel with another agent was not warranted; therefore, maintenance therapy with methazolamide was performed before and after administering the anti-cancer agent. Aggravation of cystoid macular edema was prevented, and vision improvement was achieved by oral maintenance therapy with methazolamide. In addition, the same fundus findings as shown in the right eye were detected in the left eye at 16 months after paclitaxel administration. After administering methazolamide, macular thickness was reduced, and vision was improved in the left eye. Paclitaxel administration was discontinued due to cutaneous metastasis from the breast cancer, and another anti-cancer agent was then administered. No subsequent cystoid macular edema has occurred.

We report two cases of macular edema treated with the oral administration of furosemide. The first case presented here was a 78-year-old male patient with visual disturbance of the left eye. He had been taking an oral agent for diabetes and had chronic renal failure for 7 years. From 10 days prior to the visit, he had visual disturbance of the left eye accompanied by systemic edema. There were no specific findings in the anterior segment, but sub-retinal fluid was observed in the left fundus. Macular edema was observed on fluorescein angiography and optical coherence tomography; therefore, the oral administration of furosemide was initiated. After seven days, the sub-retinal fluid disappeared. The second case was a 43-year-old female patient with visual disturbance of the left eye who had been taking hypoglycemic agents for diabetes for 13 years. There were no specific findings in the anterior segment, but flame-shaped retinal hemorrhages were scattered over both posterior poles, neovascularization was observed in the left eye, and, of particular note, sub-retinal fluid was detected in the macula of the left eye. Macular edema was also observed on fluorescein angiography and optical coherence tomography, and oral administration of furosemide was initiated. After 3 weeks, the macular edema had significantly decreased.
