refractive errors changes during uveitis activation phase
نویسندگان
چکیده
purpose: to evaluate the role of active uveitis on refractive errors changes. methods: a cohort single group study was conducted on patients with acute or recurrent uveitis. cyclorefraction was performed in both phases of active and quiescent. sphere, cylinder and sphere equivalent power were compared in active and quiescent phases and analyzed statistically. results: sixty-six patients (eighty-eight eyes) were enrolled in this study. mean age was 34 ± 14 years (range 6 to 65). 61.7% of the patients were women (54 out of 88). among the 46 cases of anterior uveitis 25 eyes (54%) were in acute and 21 eyes (46%) were in recurrent phase. spherical power changes were statistically significant in anterior non-granolumatous uveitis (p=0.039) and intermediate uveitis (p=0.002). spherical equivalent power changes were statistically significant different in intermediate uveitis (p=0.005) and panuveitis (p=0.096) groups. cylinder power did not show any significant changes in none of the above mentioned groups. this study showed that, in anterior non-granolumatous uveitis and panuveitis, spherical and spherical equivalent power changes were shifted toward myopia during active uveitis and just spherical power changes were shifted toward hyperopia in intermediate uveitis. regression analysis disclosed that only activity of uveitis and age had a statistically significant effect on the spherical power changes after adjustment (p<0.001 and p=0.036, respectively). evaluating spherical equivalent power changes, regression analysis showed that activity of uveitis and anatomic location of uveitis had a statistically significant effect (p=0.003 and p=0.001, respectively). conclusion: active uveitis plays an effective role on changing the refractive powers. the shift of these changes depends on the inflammated anatomical area; in anterior uveitis it is toward myopia and in intermediate uveitis it is toward hyperopia.

Changes in retinal and choroidal gene expression during development of refractive errors in chicks.
PURPOSE During growth, the retina analyzes the projected image to achieve a close match between eye length and focal length. Because the messengers released by retina and choroid are largely unknown, genes that are differently expressed in response to changes in the retinal image were identified. In addition, because glucagon may be important in the visual control of eye growth, the transcript ...
متن کاملChanges in Refractive Errors Related to Spectacle Correction of Hyperopia
BACKGROUND Hyperopic undercorrection is a common clinical practice. However, less is known of its effect on the change in refractive errors and emmetropization throughout the later years of childhood. OBJECTIVES To evaluate the effect of spectacle correction on the change in refractive errors in hyperopic children less than 12 years of age with or without strabismus. DATA EXTRACTION A retro...

PURPOSE To describe the theoretical effects of cyclotorted ablations on induced aberrations and determine the limits of tolerance of cyclotorsional accuracy. METHODS A method was developed to determine the average cyclotorsion during refractive surgery without a cyclotorsion tracker. Mathematical conditions were simulated to determine the optical, visual, and absolute benefits in 76 consecuti...
متن کاملRefractive errors in preterm babies.
Fifty preterm neonates were followed up at the age of 6 months and 1 year. In addition to developmental assessment, a complete ophthalmological examination was done on both visits. The largest (62%) gestational age group was of 34-36 weeks. At 6 months, none of the infants had normal vision. At 1 year of age, 64% of the babies had normal vision while incidence of myopia and hypermetropia was 16...
