Assessment of thickness of choroidal thickness in normal eyes with swept‑source optical coherence tomography
Savita Yadav, Satish Nagar

Background: Choroid is the posterior most part of the uveal tissue and has the maximum vascular supply per unit mass in the eye. The present study was conducted to assess thickness of choroidal thickness in normal eyes with swept‑source optical coherence tomography. Materials & Methods: The present study was conducted on 68 healthy subjects of both genders. Ophthalmic examination include best‑corrected visual acuity, slit lamp examination, intraocular pressure measurement using noncontact tonometry, and dilated fundus examination. Axial length measurement was performed using ocular biometry. Refractive error was measured using automated refractometer. The choroidal thickness was measured using SS‑OCT according to the standard ETDRS grid divided into different zones based on circles at 1 mm, 3 mm, and 6 mm from the centre of macula, between the Bruch’s membrane, and choroido‑scleral junction. Results: Out of 68 patients, males were 38 and females were 30. The mean thickness (μ) of central subfoveal was 298.1, nasal inner macula was 264.5, nasal outer macula was 245.3, temporal inner macula was 294.5, temporal outer macula was 282.7, superior inner macula was 306.2, superior outer macula was 302.8, inferior inner macula was 299.5 and inferior outer macula was 287.9. Conclusion: Authors found that swept‑source optical coherence tomography is useful method of measuring subfoveal choroidal thickness. Key words: Subfoveal choroidal, Swept‑source optical coherence tomography, Macule
