Filter by:This retrospective study comprised patients with cataract, corneal astigmatism, and motivation for spectacle independence. In all cases, a multifocal and monofocal Intraocular Lens was been implanted in the capsular bag. Three months postoperatively, distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity was evaluated. A patient-satisfaction and visual phenomena questionnaire was also been administered.
Dry eye syndrome (DES) is a highly prevalent ocular condition with severe consequences for the patients reaching from ocular discomfort in its simplest form up to visual impairment and corneal ulceration in severe cases. Data from epidemiological studies indicate that DES is a common disease, especially in the elderly population, affecting up to 20% of adults aged 45 years or older. Topical lubricants are a mainstay of therapy, but data on its effect on tear film thickness and the corneal residence time are lacking. Recently, a new objective method for assessment of tear film thickness by optical coherence tomography has been developed. The present study aims to investigate the corneal residence time of an established topical lubricant compared to placebo in patients with DES and healthy controls.
To evaluate the efficacy of combination therapy with ranibizumab (RBZ) and panretinal photocoagulation (PRP) versus PRP alone in patients with treatment-naive bilateral proliferative diabetic retinopathy (PDR) as measured by mean change in visual acuity (VA), mean change in central retinal thickness (CRT) as measured by time-domain optic coherence tomography (TD-OCT) and incidence of vitreous hemorrhage (VH).
The purpose of the study is to evaluate the safety and efficacy of lifitegrast ophthalmic solution compared to placebo in the treatment of dry eye.
Thyroid eye disease (TED) is an autoimmune disease that affects the eye area. The disease presents with a variety of physical findings, including bulging of the eyes (proptosis), upper and lower eyelid retraction, and swelling/inflammation of the eye itself. The disease passes through two phases: active and inactive. The active phase lasts between 18 and 24 months. During this phase, TED signs and symptoms generally worsen and then often improve. The inactive phase follows, during which the signs and symptoms of TED cease to improve and usually stabilize. Lid retraction is a cardinal sign of TED. In addition to potentially causing cornea damage due to improper lid closure, lid retraction is also very troublesome for patients due to its cosmetic appearance. The precise pathophysiology of lid retraction is poorly understood, but a leading hypothesis is that it occurs due to scarring and fibrosis in the muscles that lift the eyelid. Currently, the definitive treatment for lid retraction is surgery, which can be used to lengthen the lid itself or remove inflamed tissue from behind the eye, thus causing the eye to bulge less. In cases when patients first present to their physician with corneal ulceration or compression of the optic nerve, surgery may be performed immediately. However, in most instances, surgical procedures are delayed until the active stage of the disease has passed. Thus, most patients must endure the cosmetic and irritant symptoms of TED for up to two years. Hyaluronic Acid Gels (HAG) have been FDA approved for the treatment of facial rhytids (wrinkles). They are injected under the skin and work by increasing volume. Recently, some smaller retrospective research studies have shown that HAG is also effective in correcting upper and lower eyelid retraction in TED. Hence, HAG may be for patients with active stage TED. It is also thought that if employed early in active phase disease, HAG may also help to decrease the severity of associated symptoms and reduce the need for surgery. The purpose of the current investigation is to define the clinical utility of HAG correction of upper eyelid in active TED in terms of anatomic (lid position), quantitative (corneal dry eye signs) and qualitative effects (symptom severity and thyroid related quality of life).
The aim of this study is to evaluate the effects of subantimicrobial dose doxycycline (50 mg/d), administered for 12 wk, for patients with active moderate-severe Graves' Orbitopathy (GO).
The objective of this dose-escalation study is to evaluate the safety, tolerability and efficacy of AMA0076 in reduction of intraocular pressure in subjects with ocular hypertension or primary open-angle glaucoma.
The primary purpose of this study is to assess the efficacy, tolerability and safety of RX-10045 Ophthalmic Solution in patients with Dry Eye Disease.
This study will evaluate the safety and efficacy of a carboxymethylcellulose based eye drop formulation compared with carboxymethylcellulose based preservative-free lubricant eye drops (OPTIVE™) in subjects with dry eye disease.
To assess the comfort preference of ISTA Tears vs Systane in patients with dry eye disease (DED)
