Purpose: To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH).
Methods: By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS).
Purpose: To ascertain the anatomic factors that help achieve non-surgical sealing in full thickness macular hole (FTMH).
Methods: Retrospective collaborative study of FTMH that closed without surgical intervention.
Results: A total of 78 patients (mean age 57.
Background: To describe management of a case of intraocular lens (IOL) and capsular bag (CB) dislocation in an eye with an Ahmed glaucoma valve in the posterior chamber.
Case Presentation: A 75-year-old pseudophakic man with open-angle glaucoma and diabetic retinopathy developed neovascular glaucoma. After two intravitreous injections of bevacizumab and panretinal photocoagulation were administered, the new vessels regressed.
Aim: To compare the mydriatic efficacy of an ophthalmic insert (Mydriasert, MY) versus phenylephrine and tropicamide (PT) eye drops.
Methods: Two controlled, prospective, randomized, single-blind studies were performed. In the first study, a total of 80 eyes from 40 outpatient-clinic patients were analyzed.
The purpose of this study was to assess the effects of transforming growth factor beta (TGF-β) inhibitor peptides (P17 & P144) on early laser-induced choroidal neovascularization (LI-CNV) lesions in rats, two weeks after laser CNV induction. Seventy-one Long Evans rats underwent diode laser application in an established LI-CNV model. Baseline fluorescein angiography (FA) was performed 14 days following laser procedure, and treatments were administered 16 days post-laser application via different administration routes.

ApoE-deficient mice (apoE(-/-)) are a well-established model of genetic hypercholesterolemia and develop retinal alterations similar to those found in humans with AMD. Thus supplementation with lutein or multivitamin plus lutein and glutathione complex (MV) could prevent the onset of these alterations.

Forty-four patients with AMD were randomly divided into two groups that received placebo (n = 21) or a nutritional supplement (n = 23, 12 mg of lutein and 280 mg of DHA daily). Heterochromatic flicker photometry was used to determine the MPOD.

Methods: Sixty-one Long-Evans rats underwent diode LI-CNV model. Forty-eight hours later, treatment was administered.
Purpose: To evaluate intravitreal bevacizumab (IVB) combined with grid laser photocoagulation in macular edema (ME) secondary to branch retinal vein occlusion (BRVO).
Methods: Eight eyes (8 patients) with ME associated with BRVO with at least 3 months of evolution since symptom onset were included. All subjects underwent measurement of best-corrected visual acuity (BCVA) and imaging with spectral domain optical coherence tomography (SD-OCT) at baseline and 1, 3, 6, and 12 months.
Purpose: To estimate the prevalence and causes of bilateral blindness and visual impairment in an urban institutionalized population aged 65 years and older.
Methods: A total of 392 nursing home residents completed a standardized eye examination, including measurement of visual acuity (VA), intraocular pressure, lens opacity grading, indirect ophthalmoscopy, and photography of the macular area. The major causes of vision loss identified for all participants were blindness and visual impairment.
Purpose: Apolipoprotein E(-/-) deficient (apoE(-/-)) mice develop hypercholesterolemia, atherosclerosis, and retinal alterations. We studied the oxidative status and vascular endothelial growth factor (VEGF) expression in murine retinal pigment epithelium-choroid (RPE) and Bruch's membrane (BM) ultrastructure and the effect of zeaxanthin.
Methods: Ten 6-month-old C57BL/6 and 40 apoE(-/-) mice were divided into four groups (n = 10 each) and fed different diets for 12 weeks based on body weight: wild type (WT) and apoE(-/-) (AE-Con) mice standard rodent chow; apoE(-/-) mice (AES) standard rodent chow with ascorbate (800 mg/kg), tocopherol (1053 mg/kg), and zinc (135 mg/kg); and apoE(-/-) mice the last diet plus zeaxanthin with either 0.
Purpose: To determine the role of the retinal pigment epithelium (RPE) in the development of laser-induced choroidal neovascularization (CNV) by selective damage with sodium iodate (SI).
Methods: In group 1, diode laser photocoagulation was applied to the right eye of Long-Evans rats (n = 11). In group 2 (n = 11), SI was administered intravenously at a dose of 40 mg/kg of body weight 2 days after photocoagulation.
Purpose: To present a patient with a prepapillary vascular loop, a congenital anomaly that has been associated with vitreous hemorrhage and retinal vascular occlusion, who underwent refractive surgery.
Methods: A 45-year-old man with 2.00 diopters (D) of myopia and a unilateral prepapillary arterial loop presented with an interest in LASIK.
Objectives: To assess the association between the thickness of the retinal nerve fiber layer (RNFL), assessed by optical coherence tomography (OCT), retinal periphlebitis (RP), and multiple sclerosis (MS) disease activity.
Methods: We studied a prospective cohort of 61 patients and 29 matched controls for 2 years, performing a neurologic assessment every 3 months and an ophthalmologic evaluation, including OCT scans, every 6 months. Baseline MRI studies were also carried out from which brain volume and lesion load were assessed.
Purpose: To evaluate the role of optical coherence tomography (OCT) in determining choroidal neovascularization (CNV) activity before and after photodynamic therapy (PDT) in patients with age-related macular degeneration (ARMD).
Design: Prospective observational case series.
Setting: Institutional study.
