Currently, a disproportionate number of textbook figures and photographs are of eye conditions in white patients. Many ocular conditions can appear differently in individuals of color or those with darker skin. The purpose of this page is to share images of both common and rare pathology of the external, anterior, and posterior segments in patients of color. The American Academy of Ophthalmology's Committee for Resident Education’s DEI workgroup initiated this image collection to serve as a source for education and future versions of the Basic and Clinical Science Course (BCSC) and other texts.

Visit the Academy website to learn more about its commitment to diversity, equity, and inclusion in the ophthalmic community and review educational resources related to DEI in ophthalmology.

• 

  8-year-old African-American boy with limbal vernal keratoconjunctivitis (OU) and shield ulcer plaque (OS)

• 

  Vernal keratoconjunctivitis (VKC) is a severe disease which occurs mainly in pediatric age and is characterized by a severe and often bilateral chronic inflammation of the ocular surface. The diagnosis is generally confirmed by the finding at the ocular examination of conjunctival hyperemia, papillary hypertrophy in the tarsal conjunctiva, giant papillae and papillae in the limbus region.

Vitiligo

  Vitiligo.

Vitreous base avulsion

  Patient in UAE with vitreous base avulsion

Vogt’s striae

• 

  Vogt’s striae are vertical folds at the level of the posterior stroma and Descemet’s membrane , seen in patients of keratoconus. They occur in the area of maximal thinning and are best seen with a wide slit-lamp beam. These are stress lines that can be made to disappear with gentle pressure at the limbus.

Unilateral melanocytosis

• 

  A 58-year-old African American woman with diffuse unilateral melanocytosis affecting the left eye (A) and normal clinical findings in the right eye (D). B, C, Horizontal optical coherence tomography (OCT) scans through the fovea show bilaterally a normal retina with no view of the sclerochoroidal interface in the study eye (B). Magnification of OCT scans shows a thickened choroid in the study eye (E) compared with the opposite eye (F, white arrows: sclerochoroidal junction).

Xeroderma pigmentosum 

• 

  Facial lentigines and ocular abnormalities in patients of different ethnicities who have xeroderma pigmentosum (XP). A, Case 1 is a 5-year-old African American XP-C patient (XP444BE) with lentigines on her skin. B, Case 2 is a 13-year-old First Nations XP-C patient (XP83BE) with many lentigines, ocular surface injection, and sunburn. C, Case 3 is a 39-year-old Hispanic XP-C patient (XP131BE) who is originally from the Dominican Republic. The patient has a history of skin cancer but no history of eyelid or ocular surface cancer. Many prominent lentigines are seen on her face and neck. The patient was fairly darkly pigmented when younger, but now pigmentation has been lost, resulting in hypopigmented areas. D, Case 4 is a 46-year-old Caucasian XP-C patient (XP1BE). 33–35 She underwent bilateral orbital exenteration at ages 32 and 36 years because of recurring invasive squamous cell carcinoma of the ocular surfaces and basal cell carcinoma of the lids, including 1 squamous cell carcinoma that occurred on the palpebral conjunctiva of the upper eyelid, a non–sun-exposed area. 36 This patient, originally light-skinned, has many darkly pigmented lentiginous areas on her face. She died of uterine cancer at age 49 years.

• 

  Lid and ocular surface manifestations in patients with xeroderma pigmentosum (XP). A, Conjunctival melanosis (arrows) in case 5, an 8-year-old Asian Indian XP-C patient (XP417BE). Note the feeder vessels to lesions (arrows). B, Early pterygium (arrowhead) and lid pigmentation (arrow) in case 2. C, Severe ectropion, entropion, and ocular inflammation in case 3. D, Lid margin keratinization (arrow) and loss of lashes in case 6, a 14-year-old patient (XP243BE). The patient has a history of skin cancer but no history of ocular surface cancer. Lentigines are present on the eyelids, and the patient has bilateral pterygium (arrowhead) and ectropion. The patient has decreased best-corrected visual acuity, possibly due to amblyopia. Localized corneal clouding at the leading edge of pterygium was suspicious for early malignancy, and biopsy was recommended.
