Levosulpiride for the treatment of diabetic macular oedema: a phase 2 randomized clinical trial.

BACKGROUND/OBJECTIVE: The prokinetic levosulpiride elevates vasoinhibin levels in the vitreous of patients with proliferative diabetic retinopathy (PDR) suggesting clinical benefits due to the anti-vasopermeability and anti-angiogenic properties of vasoinhibin. We investigated the biological activity of levosulpiride in centre-involving diabetic macular oedema (DME). PATIENTS/METHODS: Prospective, randomized, double-blinded, dual-centre, phase 2 trial in patients with centre-involving DME orally treated with placebo (n = 17) or levosulpiride (n = 17) for 8 weeks or in patients with PDR undergoing elective pars plana vitrectomy and receiving placebo (n = 18) or levosulpiride (n = 18) orally for the 1 week before vitrectomy. RESULTS: Levosulpiride improved changes from baseline in best-corrected visual acuity (p ≤ 0.037), central foveal thickness (CFT, p ≤ 0.013), and mean macular volume (MMV, p ≤ 0.002) at weeks 4, 6, and 8 compared to placebo. At 8 weeks, the proportion of eyes gaining ≥5 ETDRS letters at 4 m (41% vs. 28%), losing ≥21 µm in CFT (55% vs. 28%), and dropping ≥0.06 mm3 in MMV (65% vs. 29%) was higher after levosulpiride than placebo. The overall grading of visual and structural parameters improved with levosulpiride (p = 0.029). Levosulpiride reduced VEGF (p = 0.025) and PlGF (p = 0.008) levels in the vitreous of PDR patients. No significant adverse side-effects were detected. CONCLUSIONS: Oral levosulpiride for 8 weeks improved visual and structural outcomes in patients with centre-involving DME by mechanisms that may include intraocular upregulation of vasoinhibin and downregulation of VEGF and PlGF. Larger clinical trials evaluating long-term efficacy and safety are warranted.

Micropulse laser in patients with refractory and treatment-naïve center-involved diabetic macular edema: short terms visual and anatomic outcomes.

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.

Association Between First- and Third-Month Responses to Intravitreal Ranibizumab for Diabetic Macular Edema.

Purpose: This work examines the relationship between first- and third-month anatomical and visual response with antivascular endothelial growth factor for diabetic macular edema. Methods: We prospectively evaluated 58 eyes with center-involved diabetic macular edema. Response was categorized upon the anatomical status after 3 monthly doses based on the reduction of central macular thickness (CMT) from baseline (≥20% or not). Correlation analysis between the anatomical response status, gained letters, optical coherence tomography morphological features, and other baseline characteristics were obtained. Results: Twenty-five eyes (43.1%) achieved an anatomical reduction of ≥20% at the third month. Those with a reduction of ≥20% of CMT had subretinal fluid (P < .01), lower hemoglobin A1c values (P < .01), lower proportion of intraretinal cysts (P < .01), a greater anatomical reduction, and visual improvement at the first month of treatment. Multiple logistic regression analysis, showed that the change of CMT after the first injection was an independent predictor for the anatomical reduction of ≥20% after the loading phase (P < .05). Best corrected visual acuity gain after the first dose showed a significant association with an improvement of ≥10 letters after the loading phase (P < .05), but not for macular thickness reduction. Conclusions: First month anatomical reduction was associated with the anatomical response at 3 months (P = .042) after monthly ranibizumab therapy. Visual improvement at the first month was predictive only for the visual outcome after the 3 monthly doses (P = .032).

Different approaches in the management of macular hemorrhage: Case reports and a literature review. / Diferentes abordajes en el manejo de las hemorragias maculares: reporte de casos y revisión de literatura.

INTRODUCTION: Macular hemorrhages result in a sudden and profound loss of vision. The primary treatment modalities include observation, intravitreal injection of antiangiogenic drugs, neodymium-doped yttrium aluminum garnet hialoidotomy, intravitreal injection of gas with or without tissue plasminogen activator, as monotherapy or combined with surgery. In this paper, we report four cases of macular hemorrhages of different causes treated with different approaches, and we review the literature in this regard. CASE PRESENTATION: All four patients presented different causes of macular hemorrhage. The first case had a preretinal hemorrhage due to a Valsalva retinopathy and was treated with surgery. Case 2 had a multilevel macular hemorrhage due to a rupture of a retinal arteriolar macroaneurysm and was treated with pneumatic displacement, laser, and intravitreal ranibizumab. Case 3 presented an extensive subretinal hemorrhage due to a choroidal rupture after high-energy ocular trauma that was also successfully treated with surgery. The last case was a preretinal hemorrhage due to diabetic retinopathy managed with neodymium-doped yttrium aluminum garnet laser. Different treatment approaches were successfully performed in all cases with good outcomes. CONCLUSION: There is an extensive range of options available for the management of macular hemorrhages, and the best option depends on the characteristics of each particular case. Proper and timely management of these diseases can achieve an excellent visual outcome, especially if the location of the hemorrhage is preretinal.

The role of various imaging techniques in identifying and locating intraocular foreign bodies related to open-globe injury: three case reports and literature review. / Papel de distintas técnicas de imagen para identificar y localizar cuerpos extraños intraoculares relacionados con trauma ocular abierto: reporte de tres casos y revisión de la literatura.

BACKGROUND: Determining the precise location of intraocular foreign bodies is crucial for the management of patients with open-globe injury. Computed tomography is the most common method for detecting intraocular foreign bodies in the posterior segment. In this article, we describe three cases of open-globe injury with different types of intraocular foreign bodies in the posterior segment that were accurately located using computed tomography scans and B-scan ultrasonography. CASE PRESENTATION: Each of the three cases of open-globe injury described in this report had different types of ocular trauma, clinical symptoms, and intraocular foreign bodies. Computed tomography scans showed the exact location of the intraocular foreign bodies in the posterior segment in two of the three cases. A B-scan ultrasound was used to determine the location of a non-metallic intraocular foreign body in the third case. All three patients had intraocular foreign bodies, and one of them had an additional orbital foreign body. Case 1 had a perforating eye injury with the additional intraorbital foreign body; Cases 2 and Case 3 had different types of intraocular foreign bodies and prognoses. Various treatment approaches were used, ranging from observation to surgery, depending on the location of the intraocular foreign bodies, and all cases were successfully managed. These three cases show that proper use of various types of imaging tests is indispensable in the context of an intraocular foreign body related to open-globe injury. CONCLUSION: Imaging techniques are crucial for the detection of an intraocular foreign body, and computed tomography is one of the simplest and most useful, especially in cases of open-globe injury.

Electric Shock Retinopathy: Case Report of a Late Retinal Manifestation.

Purpose: This is a case report of a male patient who suffered a high-voltage electrical burn and presented with bilateral pigmentary retinopathy. Methods: A 40-year-old man presented with bilateral vision loss following a high-voltage electrical injury sustained 10 years earlier. Family history, ocular history, and anterior segment evaluation were unremarkable. Results: Fundus examination revealed bilateral optic disc pallor, widespread areas of chorioretinal atrophy, and pigmentary changes surrounding the optic disc that partially involved the macula with some spared areas located on the superior retina. Conclusions: Retinal manifestations following a high-voltage electrical injury can resemble other hereditary and inflammatory diseases with similar clinical patterns, therefore, a meticulous family, medical, and clinical evaluation is essential.
