The beta and gamma-PPA areas were also measured. The ovality and area of the BMO and the optic disc were measured. The margins of the optic disc were determined in the SLO images, and that of the BMO in the SD-OCT images. This was a cross-sectional study of 94 eyes of 56 subjects 77 eyes were diagnosed with primary open-angle glaucoma and 17 eyes as normal. To examine the morphology of Bruch's membrane opening (BMO), optic disc, and peripapillary atrophy (PPA) by scanning laser ophthalmoscopy (SLO) and spectral-domain optical coherence tomography (SD-OCT), and to determine their association with the axial length and visual field defects. Nakanishi, Hideo Suda, Kenji Yoshikawa, Munemitsu Akagi, Tadamichi Kameda, Takanori Ikeda, Hanako Ohashi Yokota, Satoshi Kurimoto, Yasuo Tsujikawa, Akitaka Between 4 and 19 years old, mean cycloplegic axial dimension of the lens is slightly decreasing in emmetropic and hyperopic eyes, whereas in myopic eyes is constant.Īssociation of Bruch's membrane opening and optic disc morphology to axial length and visual field defects in eyes with primary open-angle glaucoma. A little role in human eye growth is also played by increasing depth of the anterior chamber. Growth of the axial length is mainly caused by increasing axial length of vitreous cavity. Growth of the axial length of the emmetropic eyes is finished at the age of 12, in hyperopic eyes in the age of 11 and in myopic eyes growth is proportional until the age of 14 and then significantly accelerates. Then we used ultrasound biometer Ocuscan (Alcon, USA), to measure axial length of the eye, axial length of the vitreous cavity, axial dimension of the lens and axial depth of the anterior chamber. Total and corneal refraction was examined with autokeratorefractometer (Nikon NRK-8000). All measurements were performed after cycloplegia with 1% tropicamidum (Polfa Warszawa). We examined 183 children (363 eyes) aged 4 to 19 with emmetropia, myopia and hyperopia. The aim ot this study was to evaluate changes ot axial dimensions ot the eye during growth in emmetropia, myopia and hyperopia. Katuzny, BartÅ‚omiej J Koszewska-KoÅ‚odziejczak, Aleksandra Domestic cats should be included in the animals in which myopia can be detected at a young age, with a likelihood of progression to emmetropia as cats mature.
Domestic shorthair cats were significantly more likely to be myopic than were domestic mediumhair or domestic longhair cats. Mean refractive error changed significantly as a function of age, and kittens had greater negative refractive error than did adult cats. Correlations were detected between age and breed and between age and refractive states of feline eyes.
Mean axial globe length, anterior chamber length, and vitreous chamber depth were 19.75 ± 1.59 mm, 4.66 ± 0.86 mm, and 7.92 ± 0.86 mm, respectively. Eyes with longer axial length at birth had smaller increases in axial length at 3 years (p 1 year old) was -0.39 ± 0.85 D. Cycloplegic autorefraction (Canon Autorefractor RK-F1) and optical biometry (IOLMaster) were performed 3 years later. Eye shape was assessed by an oblateness index, calculated as 1 - ( axial length/width) or 1 - ( axial length/height). A subset of 173 full-term newborn infants from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort underwent magnetic resonance imaging (MRI) to measure the dimensions of the internal eye. To determine if eye size and shape at birth are associated with eye size and refractive error 3 years later.
