The purpose of this trial is to compare the ability of two doses of OT-551 ophthalmic solution and drug-free solution to safely and effectively prevent or delay the progression of nuclear cataracts that frequently develop as a result of vitrectomy (surgery for retina repair), thereby avoiding the need for a second surgery (cataract removal). Victrectomies involve removal of the jelly-like substance (vitreous) that is located in a cavity behind the lens.

The purpose of this study is to evaluate the pharmacokinetics (PK) of dexamethasone phosphate ophthalmic solution delivered via the EyeGate® II Drug Delivery System (EGDS) in patients und...
To compare the macular volume of patients treated with a 3-month course of topical Nepafenac (0.1% solution) to patients treated with a placebo course following epiretinal membrane surgery...
Fundus autofluorescence (FAF) at the macula originates from hyperfluorescence from retinal pigment epithelium (RPE) and blockage of hyperfluorescence by macular pigment. Investigators eval...
Vitrectomy with membrane peeling has developed to be the gold-standard in treatment of epiretinal membranes. Due to the possibility of vitrectomy induced cataract, in many ophthalmic surgi...
The purpose of the study is to evaluate retinal thickness change and the occurrence of central structural retinal changes after uneventful small-incision cataract surgery in eyes with asym...
To compare choriocapillaris perfusion of the fovea between patients with idiopathic epiretinal membrane (iERM) and normal controls and determine whether surgery affects it.
This case involved a 75-year-old female with left-eye epiretinal membrane (ERM) and cataract who developed serious eye disorders during vitreous surgery due to methylrosaniline chloride (MRC) being mi...
To demonstrate factors related to the presence of subfoveal detachment (SD) secondary to epiretinal membrane (ERM) and to characterize the predictors for the resolution of SD after membrane peeling.
To assess the impact of combined phacoemulsification-vitrectomy and sequential surgery for idiopathic epiretinal membrane (ERM) on refractive error (RE) and macular morphology.
To describe the functional and anatomical outcomes of pars plana vitrectomy with epiretinal membrane and internal limiting membrane peel in eyes with and without ectopic inner foveal layers (EIFLs).
A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)
The pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. It is proportional to the osmolality of the solution.
Vitreoretinal membrane shrinkage or contraction secondary to the proliferation of primarily retinal pigment epithelial cells and glial cells, particularly fibrous astrocytes, followed by membrane formation. The formation of fibrillar collagen and cellular proliferation appear to be the basis for the contractile properties of the epiretinal and vitreous membranes.
Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).
A sensory branch of the trigeminal (5th cranial) nerve. The ophthalmic nerve carries general afferents from the superficial division of the face including the eyeball, conjunctiva, upper eyelid, upper nose, nasal mucosa, and scalp.
