Evaluation of Carboxymethylcellulose Sodium plus Glycerin (Optive®) in Ocular Discomfort after Anti-Vascular Endothelial Growth Factor Intravitreal Injection Therapy: A Prospective Study.

OBJECTIVE: The aim of this study was to evaluate the efficacy of a mix of carboxymethylcellulose and glycerin (Optive®) after intravitreal injection therapy (IVT) with anti-vascular endothelial growth factor for reducing ocular discomfort in patients. METHODS: We prospectively included patients who were naïve to any IVT. No artificial tear treatment was prescribed after the first IVT. After the second IVT, all patients instilled 3 drops per day of Optive® for 3 days. Every patient answered a questionnaire concerning the ocular discomfort at 72 h after both IVTs and a questionnaire about tolerance to treatment after the second IVT. RESULTS: We included 45 patients (mean age 72.3 years [range 23-94], 25 females); 14 (34.1%) reported a feeling of grittiness after the first IVT but not after the second (p = 0.01); 12 (29.3%) complained of global discomfort after the first IVT but not after the second (p = 0.14); and 11 (26.8%) reported a watery eye after the first IVT but not after the second (p = 0.21); 37/45 (82%) patients felt ocular discomfort after IVT. CONCLUSION: Most patients felt ocular discomfort after IVT. Instillation of Optive® significantly alleviated the feeling of grittiness for more than half of the patients.

ABNORMAL VASCULAR COMPLEX WITHIN AN IDIOPATHIC EPIRETINAL MEMBRANE IMAGED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY.

PURPOSE: To report the case 70-year-old patient presenting with preretinal, abnormal vascularization accompanying an idiopathic epiretinal membrane (ERM), identified by optical coherence tomography angiography. METHODS: Observational case report of one patient. RESULTS: The authors describe the case of a patient presenting with an ERM on the right eye since March 2011, diagnosed by fundus biomicroscopy and spectral domain optical coherence tomography (Spectralis; Heidelberg Engineering, Heidelberg, Germany). At the last follow-up visit, the patient had a Snellen best-corrected visual acuity of 20/32 in her right eye and 20/20 in her left eye. Although on spectral domain optical coherence tomography the aspect on the right eye was unchanged since prior examination, optical coherence tomography angiography (Angiovue; Optovue, Fremont, CA) was able to reveal a high-flow, abnormal vascular network in the preretinal manual segmentation corresponding to the ERM. CONCLUSION: Spectral domain optical coherence tomography, routinely performed in these patients, may underestimate the presence of abnormal vascularization, as both preretinal neovascular complexes and thick ERMs appear as hyperreflective structures. Optical coherence tomography angiography allows a fast and depth-resolved visualization of these abnormal vascular complexes inside idiopathic ERMs. Diagnosis of a vascularized epiretinal structure could be noteworthy before decision of retinal surgery.
