Reply to the Letter by Uzun and Pehlivan Entitled ‘Characteristics of Hyperautofluorescent Choroidal Vessels within the Macular Atrophic Area Using Spectral-Domain Optical Coherence Tomography'

(2 men, 2 women) (15.4%); hyperlipidemia in 2 men (7.7%); diabetes mellitus in 2 men (7.7%); vasculopathies in 2 women (7.7%), and glaucoma in 3 men (11.5%). We did not obtain data pertaining to sleep patterns, exercise, consumption of drinks with/without caffeine, or body mass indexes. As to arteriosclerosis risk factors, such as hypertension, smoking, diabetes mellitus, and hyperlipidemia [4] , there were 10 such patients (58.8%) in group 1 and 11 (42.3%) in group 2. There were no significant differences between these two groups (p = 0.51). Refractive error and intraocular pressure were –1.8 ± 3.4 diopters and 13.6 ± 3.2 mm Hg in group 1, and –2.0 ± 3.9 diopters and 14.3 ± 3.1 mm Hg in group 2, respectively. There were no significant differences between the two groups (p = 0.83 in refractive error, p = 0.42 in intraocular pressure). Diurnal variation and time course also reportedly affect CT [3, 5] , but we captured the fundus autofluorescence and optical coherence tomographic images in succession on the same day, such that they would be unlikely to seriously affect CT with or without hyperautofluorescent choroidal vessels on fundus autofluorescence. We thank Dr. Uzun and Dr. Pehlivan for their interest in our article [1] . Our research data were obtained, in part, from the detailed medical records of all 43 patients studied. There were no pregnant patients, and the menstrual cycle status of the female patients was not considered in this study. No patients with strabismus were included in our study. Sleep, exercise, smoking, and consumption of alcohol or drinks with/without caffeine, as well as body mass indexes, and systemic blood pressure have all been reported to significantly affect choroidal thickness (CT) measurements [2, 3] as Drs. Uzun and Pehlivan suggested [1] . In the group with hyperautofluorescent choroidal vessels on fundus autofluorescence (group 1, 17 patients), we confirmed the presence of the following factors: smoking in 3 men (17.6%); consumption of alcohol in 3 men (17.6%); hypertension in 8 patients (5 men, 3 women) (47.1%); hyperlipidemia in 2 women (11.8%), and vasculopathies in 3 patients (1 man, 2 women) (17.6%). In the group without hyperautofluorescent choroidal vessels on fundus autofluorescence (group 2, 26 patients), we confirmed the presence of the following factors: smoking in 7 patients (5 men, 2 women) (26.9%); consumption of alcohol in 2 men (7.7%); hypertension in 4 patients Received: June 1, 2016 Accepted: June 7, 2016 Published online: July 6, 2016
