In this paper, skew cyclic and skew constacyclic codes over finite non-chain ring R = F_q+uF_q+vF_q, where q= p^m, p is an odd prime and u^{2}=u, v^{2}=v, uv=vu=0 are studied. We show that Gray image of a skew cyclic code of length n over R is a skew quasi-cyclic code of length 3n over F_q of index 3. Structural properties of skew cyclic and skew constacyclic over R are obtained. Further, gener...

Background . Research and maintenance of an acceptable quality life is considered to be the main aim treating chronic incurable disease including glaucoma. The To perform a comprehensive assessment patients with glaucoma when using various types surgical conservative treatment before 1 month after treatment. Material methods We carried out randomized controlled study which included 229 patients...

PURPOSE To compare the efficacy of problem-solving therapy (PST) with supportive therapy (ST) to improve targeted vision function (TVF) in age-related macular degeneration (AMD). DESIGN Single-masked, attention-controlled, randomized clinical trial with outcome assessments at 3 months (main trial endpoint) and 6 months (maintenance effects). PARTICIPANTS Patients with AMD (n = 241) attendin...

BACKGROUND Chronic central serous chorioretinopathy (cCSC) is an eye disease characterized by an accumulation of serous fluid under the retina. It is postulated that this fluid accumulation results from hyperpermeability and swelling of the choroid, the underlying vascular tissue of the eye, causing a dysfunction of the retinal pigment epithelium. This fluid accumulation causes neuroretinal det...

OBJECTIVE To demonstrate superiority of ranibizumab 0.5 mg monotherapy or combined with laser over laser alone based on mean average change in best-corrected visual acuity (BCVA) over 12 months in diabetic macular edema (DME). DESIGN A 12-month, randomized, double-masked, multicenter, laser-controlled phase III study. PARTICIPANTS We included 345 patients aged ≥18 years, with type 1 or 2 di...

PURPOSE To compare the effectiveness of low vision rehabilitation (LVR) and basic low vision (LV) in a single masked multicentre randomised controlled trial (RCT). METHODS Three hundred and thirty patients eligible for US. Veterans Affairs (VA) healthcare services with primary eye diagnosis (better-seeing eye) of macular disease and best-corrected distance visual acuity of 0.40-1.00 logMAR (6...
