Geometric formula to calculate the curved surface area of a spherical dome and anatomical dimensions of a standard eyeball. a. If the radius of the dome is r, the height of the dome is h, the radius of the bottom is c, and the base area is B, the curved surface area (S), excluding B of the dome is S = 2πrh = π (c2 + h2). b. The area of the whole retina and the retina up to the equator. These dimensions were derived from a textbook [23]. c. The areas in S are equal to the areas of circles with radii of 18.6 mm and 15.6 mm, calculated via the formula presented in (a)
