Estimation of ocular volume from axial length.
BACKGROUND/AIMS To determine which biometric parameters provide optimum predictive power for ocular volume. METHODS Sixty-seven adult subjects were scanned with a Siemens 3-T MRI scanner. Mean spherical error (MSE) (D) was measured with a Shin-Nippon autorefractor and a Zeiss IOLMaster used to measure (mm) axial length (AL), anterior chamber depth (ACD) and corneal radius (CR). Total ocular v...
متن کاملAxial Length and Ocular Development of Premature Infants without ROP
Purpose To investigate the ocular parameters of premature infants without ROP at gestational age (GA) more than 28 weeks and their relationship with growth parameters. Methods 76 preterm infants without ROP and 65 term infants were involved to undergo portable slit lamp, RetCam3, ultrasonic A-scan biometry, and cycloplegic streak examination at their 40 weeks' postconceptional ages (PCA). Ocu...
متن کاملOcular axial length in unilateral congenital cataracts and blepharoptosis.
Biometry performed in patients with unilateral dense congenital cataracts and unilateral complete blepharoptosis did not show a consistent elongation of the involved eye. The antero-posterior axis of the visually deprived eye was longer than that in the normal fellow eye in some but shorter or unchanged in other patients. These findings are in accord with the hypothesis gained from monkey exper...
متن کاملScleral Cross Section Area and Volume and Axial Length
PURPOSE To examine whether the scleral cross sectional area and estimated scleral volume are associated with a longer axial length in human eyes. METHODS Histologic anterior-posterior sections running through the pupil and the optic nerve head were examined. Using a light microscope, we measured the thickness of the sclera at the limbus, ora serrata, equator, midpoint between equator and post...
متن کاملThe effect of Ramadan fasting on micronutrients and their relationship with the ocular axial length and anterior chamber depth
Introduction: The present study aimed to assess the effects of Ramadan fasting on micronutrients and their correlations with ocular biometry. Methods: This prospective study was conducted on 89 healthy volunteers (51 males and 38 females) with the mean of 34.98±9.10 years in Mashhad, Iran. Participants received complete ophthalmic and systemic examinations one week before and one week after the...
