Choroidal thickness in psoriasis

International Ophthalmology, 2016
Our aim was to compare the choroidal thickness in psoriasis patients and age- and gender-matched healthy volunteers. A total of 38 psoriasis cases and 38 age- and gender-matched controls were evaluated. The left eye was evaluated in all subjects.

Choroidal thickness in keratoconus

International Ophthalmology, 2019
Keratoconus is an ectatic eye disease characterized by progressive thinning and steepening of the cornea which leads to irregular astigmatism and visual function loss. Determination of choroidal thickness in keratoconus patients may help us to better understand and manage the keratoconus disease.

Choroidal vascularity index and choroidal thickness assessment in vitiligo

Clinical and Experimental Optometry, 2023
Vitiligo is a skin disease characterised by depigmentation and loss of melanocytes. Melanocyte loss may not be limited to the skin in vitiligo, and various abnormalities may occur in the choroid, which is dense in melanocytes.To evaluate structural changes in the choroid by measuring choroidal thickness and vascularity index using optical coherence ...

In Vivo Choroidal Thickness Measurement

American Journal of Ophthalmology, 1979
We developed a system that permits exceptionally accurate measurements of human choroidal thickness in vivo by means of ultrasound. With minicomputer techniques, the complementary functions of the time and spectral domains of reflected sound can be used to permit measurements accurate to less than 20 mu at 10 MHz center frequency.
