Reported here is a case of intralenticular sustained-release dexamethasone implant (Ozurdex®, Allergan, Irvine, CA, USA) present for 1 year with effective treatment of refractory diabetic macular edema without rapid cataract formation. The crystalline lens remained stable for 12 months on exam despite the presence of the steroid-secreting foreign body. The diabetic macular edema resolved on exam and on optical coherence tomography. After 1 year, cataract extraction was uneventfully performed by phacoemulsification for a mild decline in visual acuity. Macular edema remains resolved 2 months following cataract removal. This is the longest reported period of observation of intralenticular Ozurdex in the literature. Ozurdex remains effective despite intralenticular location, and it can have minimal effects on cataract progression.

Abstract Purpose: To investigate longer-term functional and morphological outcomes and their predictors in diabetic macular edema (DME) following a treat and extend regimen (TER) without loading dose under ranibizumab. Methods: Patient data were reviewed and analyzed retrospectively over a period of 24 months after initiation of TER. Best-corrected visual acuity (BCVA), treatment frequency as well as quantitative and qualitative Spectral-domain Optical Coherence Tomography parameters were assessed. Results: 118 eyes of 87 patients were included. A mean of 9.742.13 injections in the first and 7.632.29 in the second year were applied. There were significant gains of BCVA and reductions in central retinal thickness from baseline to month 12 and 24 (all p<0.001). Percentage of eyes with an intact inner-/outer segment (IS/OS) junction increased from 15.3% at baseline to 42.1% at month 24 (p<0.001). An intact IS/OS junction at baseline increased the probability of having a dry retina after 12 months by 79.3% (p=0.017) and after 24 months by 88.1% (p=0.040). Less IS/OS disruption at baseline predicted longer maximum recurrence-free treatment intervals at 2 years (r=-0.345, p<0.001) and better BCVA at one year (r=-0.347, p<0.001). Baseline bigger intraretinal cysts were associated with more IS/OS disruption at 24 months (r=0.305, p=0.007). Younger age and lower BCVA at baseline were predictive for a higher BCVA gain at 24 months (p=0.046, p<0.001). Conclusion: Ranibizumab applied in a TER without loading dose in DME significantly improves visual acuity and retinal anatomical structure throughout two years. The evaluated predictors might help to guide routine clinical treatment in DME.

Purpose: The purpose of the study is to describe visual and anatomic outcomes of 5774nm micropulse laser photocoagulation in eyes with either treatment-naïve or refractory diabetic macular edema (DME) at 3 months. Methods: This was a prospective case series that recruited 23 consecutive patients (33 eyes) with center-involved DME that was either treatment-naïve or had not responded to prior treatment. Micropulse therapy was performed with the Easy Ret 577 (Quantel Medical, Cournon d’Auvergne, France) diode laser in a high-density manner in eyes with treatment-naïve or refractory DME. The primary outcome was the change of best-corrected visual acuity (BCVA; logMAR) at 1 and 3 months. Secondary outcomes were changes in the central macular thickness (CMT), thickness area, macular volume, and macular capillary leakage at 1 and 3 months. Results: There were no significant changes in BCVA at 3 months, with mean ± standard deviation (SD) of −0.08 ± 0.01 ( p = 0.228) and + 0.01 ± 0.01 ( p = 0.969) for treatment-naïve and refractory groups, respectively. The change in CMT at 3 months was statistically but not clinically significant in the treatment-naïve group only (mean ± SD; –30 ± 130 µm; p = 0.011). The macular volume and area thickness change were not statistically significant ( p = 0.173 and p = 0.148 for macular volume and area thickness, respectively) in the treatment-naïve group. There was no difference concerning the leakage area in both groups. No adverse events were reported. Conclusion: We concluded that micropulse 577nm laser therapy maintained the visual acuity and macular thickness at 3 months in both treatment-naïve and refractory DME.

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.

Background: Diabetes mellitus remains the leading cause of blindness among working age Americans with diabetic macular edema being the most common cause for moderate and severe vision loss. Objective: To investigate the anatomical and visual benefits of pars plana vitrectomy with inner limiting membrane peeling in patients with nontractional diabetic macular edema as well as correlation of integrity of outer retinal layers on spectral domain optical coherence tomography to visual outcomes. Methods: We retrospectively reviewed the charts of 42 diabetic patients that underwent vitrectomy with internal limiting membrane peeling for nontractional diabetic macula edema. The integrity of outer retinal layers was evaluated and preoperative central macular thickness and visual acuity were compared with data at 1 month, 3 months and 6 months postoperatively. The student t-test was used to compare the groups. Results: 31 eyes were included. While no differences were seen at 1 and 3 months, there was significant improvement of both central macular thickness and visual acuity at the 6 months follow up visit compared to preoperatively (357, 427 microns; p=0.03. 20/49, 20/82; p=0.03) . Patients with intact external limiting membrane and ellipsoid zone had better preoperative vision than patients with outer retinal layer irregularities (20/54, 20/100; p=0.03) and greater visual gains postoperatively (20/33, p<0.001 versus 20/81; p=non-significant). Conclusion: Pars plana vitrectomy with internal limiting membrane peeling can improve retinal anatomy and visual acuity in patients with nontractional diabetic macular edema. Spectral domain optical coherence tomography may help identify patients with potential for visual improvement.

Background. Diabetic macular edema (DME) is one of the main causes of decreased central vision. Determining the reasons for the refractoriness of DME to treatment is an urgent problem.Aims. Based on the analysis of optical coherence tomography, to study the features of pathological changes in the retina and vitreoretinal interface (VRI) in the macular zone in patients with DME.Materials and methods. We studied 587 patients (587 eyes) with diffuse DME in the setting of nonproliferative diabetic retinopathy. In addition to the standard ophthalmological examination, everyone underwent optical coherence tomography of the macular zone with an assessment of structural changes in the retina, morphometric parameters, and the state of the VRI.Results. In 351 patients (59.80 %) with DME, pathological variants of the VRI were revealed, in which the best corrected visual acuity was significantly lower, and the morphometric parameters (retinal thickness and macular volume) were signifi cantly higher. Analysis of morphostructural changes in the macular zone revealed that in pathological VRI, neuroepithelial detachment and high edema are more common, and cystic edema is larger in area compared to the group with a normal VRI. With detachment of neuroepithelium against the background of a pathological VRI, the worst morphometric data are determined, with solid exudates in the macula, the worst indices of visual loss are determined.Conclusions. The pathological VRI in patients with diabetic macular edema occurs in more than half of the cases and is characterized by a high incidence of neuroepithelial detachment, high edema, higher morphometric parameters with worse visual acuity. At the same time, the presence of neuroepithelial detachment corresponds to the worst morphometric indicators of the macular zone, and the presence of solid exudates corresponds to a lower maximum corrected visual acuity. Further research is needed to assess the effect of the listed morphostructural and morphometric changes in combination with various pathological variants of VRI on the effectiveness of DME treatment.

Introduction: Diabetic Macular Edema (DME) is an important cause of vision loss in diabetic retinopathy. Optical Coherence Tomography (OCT) is a non-invasive modality that produces high-resolution images of retinal layers. Objective: To evaluate the prevalence of DME patterns and their association with risk factors and visual acuity. Materials and Methods: In this cross-sectional study, type 2 diabetics with macular edema referred to our center during a ten-month period underwent OCT. Patients with macular edema due to causes other than diabetes and with OCT images of improper quality were excluded from the study. Four distinct patterns were found in the OCT images. A questionnaire including age, sex, duration of diabetes, serum TG and cholesterol, HbA1c, BMI and visual acuity, as well as the findings of OCT images were filled for the subjects. Results: Eighty-six eyes from 46 patients were evaluated. The most and the least common patterns were sponge-like retinal swelling (SLRS) and posterior hyaloidal traction (PHT) found in 64.0% and 5.8% of the subjects, respectively. A sub-retinal fluid pattern was more common in males (p=0.011) and in patients with serum TG > 200mg/dl (p=0.037). There were significant associations between central foveal (r=0.45, p<0.001), nasal (r=0.35, p=0.001) and temporal (r=0.32, p=0.003) thicknesses with visual acuity. Moreover, the highest thickness (462.4±119.2μm) and also the worst visual acuity (1.0±0.5logMAR) pertained to the cystoid macular edema (CME) pattern. Conclusion: Our study showed that the most common OCT pattern of DME is the sponge-like retinal swelling, while posterior hyaloidal traction has the lowest prevalence. A higher foveal thickness and a lower visual acuity are seen in the CME pattern. Nepal J Ophthalmol 2013; 5(10): 190-194 DOI: http://dx.doi.org/10.3126/nepjoph.v5i2.8727
