Ocular Albinism: Detailed Information
Ocular albinism is a group of inherited conditions affecting the pigmentation of the eyes. Key aspects include:
Characteristics
- Reduced pigmentation: Mainly affects the iris and retina.
- Vision problems: Common issues include reduced visual acuity, nystagmus (involuntary eye movements), strabismus, and photophobia (sensitivity to light).
- Type 1 (OA1): Most common form, typically X-linked inheritance affecting males more severely.
Symptoms and Effects
- Visual impairment: Range from mild to significant vision loss.
- Nystagmus and strabismus: Common associated eye movement issues.
- Photophobia: Sensitivity to light due to lack of pigmentation.
Genetics and Diagnosis
- Inheritance: Usually X-linked for OA1, affecting males primarily.
- Diagnosis: Often based on clinical findings like iris transillumination defects and visual issues.
Management
- Visual aids: Glasses or contact lenses may help.
- Low vision support: Services can assist with daily challenges.
- Protection from sunlight: Due to photophobia.
