Abstract: Albinism encompasses a group of genetic disorders characterized by partial or complete absence of melanin pigment in the eyes, skin, and hair. This article provides a comprehensive review of albinism, including its etiology, clinical manifestations, diagnostic approaches, management strategies, and recent advancements in research and treatment. By elucidating the complexities of albinism, ophthalmologists can enhance their understanding of this condition and improve patient care.

Introduction: Albinism represents a heterogeneous group of inherited disorders characterized by defects in melanin synthesis or transport. Despite its rarity, albinism poses significant challenges to patients due to its impact on visual function, skin health, and susceptibility to sun-induced damage.

Etiology: Albinism results from mutations in genes involved in melanin production, including TYR, OCA2, TYRP1, and SLC45A2. These genetic abnormalities disrupt melanin synthesis or transport, leading to hypopigmentation of the skin, hair, and eyes.

Clinical Manifestations: Individuals with albinism typically present with characteristic features such as fair skin, white or light-colored hair, and ocular abnormalities including nystagmus, photophobia, and reduced visual acuity. Ocular manifestations may include iris transillumination defects, foveal hypoplasia, and misrouting of optic nerve fibers.

Diagnostic Approaches: Diagnosis of albinism involves clinical evaluation, assessment of skin and hair pigmentation, and molecular genetic testing to identify causative mutations. Ophthalmic evaluation, including assessment of visual function, fundus examination, and optical coherence tomography (OCT), aids in characterizing ocular abnormalities associated with albinism.

Management Strategies: Management of albinism focuses on optimizing visual function, protecting the skin from sun-induced damage, and addressing psychosocial challenges associated with the condition. Visual rehabilitation may include prescription eyewear, low vision aids, and educational support services. Sun protection measures, including sunscreen use, protective clothing, and sunglasses, help mitigate the risk of sunburn and skin cancer.

Recent Advancements: Advances in molecular genetics have facilitated the identification of novel causative genes and potential therapeutic targets for albinism. Gene therapy approaches aimed at restoring melanin production or correcting genetic defects hold promise for future treatment modalities.

Conclusion: Albinism is a complex genetic disorder characterized by hypopigmentation and ocular abnormalities. Through a multidisciplinary approach encompassing genetic counseling, ophthalmic care, and psychosocial support, clinicians can improve outcomes and enhance the quality of life for individuals affected by albinism.
