  2. Corneal limbus - Wikipedia

    en.wikipedia.org/wiki/Corneal_limbus

    The corneal limbus is the border between the cornea and the sclera. [1] It is highly vascularized. [1] The corneal limbus' responsibilities include protection, healing, and controlling eye pressure. The limbus contains corneal stem cells that play key roles in corneal healing (renewing the corneal epithelium). [2]

  3. White dot syndromes - Wikipedia

    en.wikipedia.org/wiki/White_dot_syndromes

    Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.

  4. Amsler grid - Wikipedia

    en.wikipedia.org/wiki/Amsler_grid

    Amsler grid, Chart 1 There are 7 types of Amsler grid charts. All charts measure 10 cm × 10 cm (3.9 in × 3.9 in), which when viewed at a distance of 33 cm (13 in) from the eye can be used to measure defects in the central 20 degrees of the visual field .

    en.wikipedia.org/wiki/Epithelial_basement...

    Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness.EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy, is a corneal epithelial disease that may result in recurrent corneal erosions, irregular corneal astigmatism, and decreased vision.

  6. Astigmatism (optical systems) - Wikipedia

    en.wikipedia.org/wiki/Astigmatism_(optical_systems)

    A Snellen chart or other eye chart may initially reveal reduced visual acuity. A keratometer may be used to measure the curvature of the steepest and flattest meridians in the cornea's front surface. [14] Corneal topography may also be used to obtain a more accurate representation of the cornea's shape. [15]

  7. Uveitis - Wikipedia

    en.wikipedia.org/wiki/Uveitis

    Uveitis (/ ˌ juː v i. aɪ t ɪ s /) is inflammation of the uvea, the pigmented layer of the eye between the inner retina and the outer fibrous layer composed of the sclera and cornea. [1] The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris , ciliary body , and choroid .

    The lacrimal caruncle is found at the medial canthus of the eye. [1] It consists of skin, hair follicles, sebaceous glands, sweat glands, accessory lacrimal tissue and other tissues that are present in the skin and accessory lacrimal glands.

  9. Punctate epithelial erosions - Wikipedia

    en.wikipedia.org/wiki/Punctate_epithelial_erosions

    It is a characterized by a breakdown or damage of the epithelium of the cornea in a pinpoint pattern, which can be seen with examination with a slit-lamp. Patients may present with non-specific symptoms such as red eye, tearing, foreign body sensation, photophobia and burning.
