Their treatment guidelines experience constant changes with new agents that improve the results obtained with former drugs. Nowadays we can make use of a five step protocol in which topical, periocular and systemic(More)
We used (1)H NMR spectroscopy to analyze the metabolomic profile of reflex tears from patients with dry eye disorders (DEDs). 90 subjects were divided into 2 groups: (1) patients with DEDs (DEDG; n = 55) and (2) healthy subjects (CG; n = 35). Additionally, the DEDG was subdivided into 2 subgroups based on DED severity: mild-to-moderate and moderate (n = 22(More)
PURPOSE We used nuclear magnetic resonance spectroscopy of hydrogen-1 nuclei ((1)H NMR S) to analyze the metabolic profile of reflex tears from patients with dry eye disorders. METHODS We performed a prospective case-control study involving 90 participants: 55 patients diagnosed with dry eye syndrome (DESG) and 35 healthy subjects (control group, CG).(More)
BACKGROUND Oxidative stress (OS) and its biomarkers are the biochemical end point of the imbalance between reactive oxygen species (ROS) production and the ability of the antioxidant (AOX) biological systems to fight against oxidative injury. OBJECTIVE We reviewed the role of OS and its downstream signaling in aging eyes. METHODS A search of the(More)
BACKGROUND The purpose of this study was to compare the efficacy of intravitreal ranibizumab in the treatment of macular edema due to branch retinal vein occlusions (BRVO) with and without serous macular neuroretinal detachment (SMD). METHODS Forty-nine eyes of 49 patients with macular edema due to branch retinal vein occlusion (22 with SMD and 27 without(More)
PURPOSE To report a case of Coats' disease managed with the dexamethasone intravitreal implant Ozurdex(®) (Allergan, Inc., Irvine, Calif., USA) combined with retinal photocoagulation. METHODS A 46-year-old female with 20/200 visual acuity was diagnosed with Coats' disease with secondary retinal vasoproliferative tumor. An initial approach was performed(More)
