Author Response: Choroidal Thickness Change after Water Drinking Is Greater in Angle Closure Than in Open-Angle Eyes

“…We thank De Moraes et al 1 for the opportunity to emphasize the findings of our study and how they differ from their publication. 2 We reported, for the first time, the response of angle closure (AC) patients to the water-drinking test (WDT), including changes in IOP, blood pressure (BP), and choroidal thickness.…”

“…The shape of large, clinically visible choroidal detachments is a totally different situation and not relevant to this discussion. De Moraes et al 1 cite Esmaeelpour et al 13 to support their claim that ''choroidal thickness varies significantly in different areas of the posterior pole, being particularly thicker in areas farther from the fovea.'' Esmaeelpour et al 13 actually state: ''For all eyes, the mean 6 SD of ChTs were 315 6 106 lm (Central), 250 6 113 lm (Nasal), 276 6 95 lm (Temporal), 315 6 112 lm (Superior), and 293 6 106 lm (Inferior).''…”

“…AC eyes not only have greater choroidal expansion than other eyes, but their resting choroidal thickness is greater than that of OAG or control eyes, 5 including in the anterior choroid, 6 after adjusting for relevant variables like age, axial length, and IOP. The references that the letter by De Moraes et al 1 cites from Lowe 7 and from Kirsch 8 neither suggested nor documented with data any study of choroidal thickness, and neither mentioned choroidal participation in AC.…”

A comparative study of stereoacuity in patients with various grades of cataract and bilateral pseudophakia

“…[16] Our study shows that stereopsis is limited by the level of visual acuity [Table 4], probably because patients who had comparatively lower visual acuity tend to need relatively larger spatial frequencies to be present in the input images, else they would not be able to achieve stereopsis. [17] Bilateral pseudophakia group showed a significant improvement in near stereoacuity when compared with severe grade of cataract, but no statistically significant difference with mild and moderate grades of cataract ( P > 0.05).…”
