(Lepidoptera, Saturniidae) parasitoid species investigated in Fujian, China.

Westwood is a notorious defoliator of Nees that causes large economic and ecological losses in planted forests. To understand the importance of suppressing the population of on natural parasitoids, a four-years investigation was conducted in the field. Four egg parasitoid species Howard, Ishii, sp.

Effect of orthokeratology on axial length elongation in moderate myopic and fellow high myopic eyes of children.

Clinical Relevance: The effects of orthokeratology (Ortho-K) on myopic eyes was examined, providing confidence to optometrists applying Ortho-K to high myopic and anisometropic children.

Background: Ortho-K slows the progression of low to moderate myopia. The effectiveness of Ortho-K in Chinese children with fellow moderate and high myopic eyes was determined.

Short term effect of choroid thickness in the horizontal meridian detected by spectral domain optical coherence tomography in myopic children after orthokeratology.

Aim: To investigate choroidal thickness changes in the horizontal meridian after orthokeratology.

Methods: This is a prospective cross-sectional observed study. Subjects (=30; 11.

Relevant factors of estrogen changes of myopia in adolescent females.

Background: Gender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females.

[A study on the effect of the corneal biomechanical properties undergoing overnight orthokeratology].

Objective: To evaluate the changes of corneal biomechanical properties and corneal topography undergoing overnight orthokeratology treatment.

Methods: Thirty teenagers with low and moderate myopia with age of 11.67 + or - 1.

[The expression of the correction of corneal astigmatism in the point spread function analysis system of human eyes].

Objective: To investigate the ocular optical imaging quality among corneal astigmatism subjects under different corrections by using the Point Spread Function analysis system (PSF).

Methods: PSF 1000 analyzer was used to measure retinal image quality of eyes of 26 subjects with corneal astigmatism (sphere ranged from -3.00 to -6.

[Effects after orthokeratology on corneal topography and monochromic wavefront aberration].

Objective: To assess the corneal topography and monochromatic wavefront aberration among subjects using orthokeratology. Changes of ocular optical quality and related visual functions induced by corneal topography were studied.

Methods: Twenty-five young myopic subjects (50 eyes) were recruited with myopia from -1.

[Study of corrected visual performance and vision quality].

Objective: The present study was designed to examine the visual acuity (VA) and contrast sensitivity function (CSF) under three refractive correction methods, the visual performance and vision quality under different correction methods were compared and analyzed.

Methods: Twenty three college students with myopia (41 eyes, myopia range: -1.25 D approximately 9.
