To determine any association of amblyopia with educational activities, sport and social activities of students involved by amblyopia, this study was carried on. This study was conducted at Boali Hospital in Gazvin, Iran: A total of 110 patients 9 to 15 years (54.5% female and 45.5% male;mean age: 13.7 ± 3.2) with amblyopia (20/25 - 20/400) due to strabismus and/or refractive errors, and that persisted after treatment with spectacles. All children wore eyeglasses containing their refractive correction (based on cycloplegic autorefractor measurements, refined or confirmed by cycloplegic retinoscopy or subjective refinement) for acuity testing. The results indicated that, 25 (22.73%) patients with strabismus amblyopia, 40 (36.36%) patients anisometropic amblyopia, 22 (20%) patients ametropic amblyopia, 18 (16.36%) patients with strabismic mixed with anisometropia and 5 (4.55) with deprived amblyopia. Parent’s knowledge about meaning of amblyopia and amblyopia-related phenomena in 50 (45.5%) of patiens was very low. The educational level in 45 (41%) of parents were reported to be primary school, 40 (36.3%) higher school and university degrees 25 (22.7%). The sport activity in 35 (31.8%) of patients with amblyopia was very low and in 14 (12.7%) higher than others. In a comparison with other students, the educational qualification in 18 (16.4%) was very low, 35 (32%) the as equal as others and 27 (24.5%) higher than their classmate. Visual acuity with the best correction, in 75 (67%) of patients was 20/25, in 30 (27.27%) patients 20/40 or worse and in 5 (4.5%) of them 20/200 or worse. Poor eyesight and amblyopia can influence on learning, sport and social activity, and performance in school, as well as restrict choice in profession and hobbies. The parent’s knowledge of amblyopia is high efficiency of treatment of the amblyopia patient’s morale.展开更多

In order to assess the active tectonics in the area of study, morphotectonical indices such as valley index (V), ratio of valley floor to valley height (Vf), channel sinuosity index (S), mountain front faceting index (F%) and mountain front sinuosity(Smf) are studied. These investigations show that the activity is not equal in various sections along Burkh Anticline and the central part of this anticline is the most active one.展开更多

The general trends of fold axis and axial surface are E-W and the folds are less exposed by distance from mountain and plain boundary. Geometric and kinematic status investigation of folds (such as f2 fold in the middle part) and faults shows that faulting process has created some of the folds leading to their development. Such structures are described as fault-related folds. Also, analysis of geometry and mechanism of faults indicate that back thrusts have the largest influence on generation and development of folds in this region.展开更多
