    Summary
    This summary is machine-generated.

    Bietti's crystalline retinopathy, a rare genetic disorder, involves crystalline deposits in the retina and cornea. This case highlights its presence in the Middle East and progressive vision loss.

    Area of Science:

    • Ophthalmology
    • Medical Genetics

    Background:

    • Bietti's crystalline retinopathy is a rare inherited disorder characterized by lipid crystalline deposits in the retina and cornea.
    • It is associated with progressive visual impairment and is inherited in an autosomal recessive pattern.

    Observation:

    • A 23-year-old woman presented with chorioretinal dystrophy, including retinal crystalline deposits, geographic atrophy of the retinal pigment epithelium, and choriocapillaris in the posterior pole.
    • Fine pigment clumps were noted in the midperiphery, and corneal crystalline deposits were observed in the stroma and epithelium.

    Findings:

    • The patient was diagnosed with Bietti's crystalline retinopathy, exhibiting progressive worsening of visual acuity and visual fields over two years.
    • This case represents the first documented instance of Bietti's crystalline retinopathy in the Middle East.

    Implications:

    • The findings contribute to the understanding of the geographic distribution and clinical presentation of Bietti's crystalline retinopathy.
    • Corneal crystalline deposits appear more prevalent in Caucasian populations with this condition compared to Asian populations.
    • The study reinforces the autosomal recessive inheritance pattern and worldwide distribution of Bietti's crystalline retinopathy, often associated with parental consanguinity.
