Distrofia cristalina de Bietti
ORPHA:41751CID-10 · H35.5CID-11 · 9B61OMIM 210370DOENÇA RARA

A Distrofia Cristalina de Bietti (DCB) é uma doença genética rara e progressiva, de herança autossômica recessiva (o que significa que a pessoa precisa herdar um gene específico de cada um dos pais para desenvolvê-la), que causa a degeneração da retina e de suas camadas de suporte. Geralmente se manifesta entre os 20 e 30 anos de idade e é caracterizada por pequenos depósitos cristalinos brilhantes na parte de trás da retina e na borda da córnea, além do endurecimento (esclerose) dos vasos sanguíneos da coroide (uma camada de vasos que fica abaixo da retina). Os sintomas incluem cegueira noturna, diminuição da visão e pontos cegos próximos ao centro da visão, podendo levar à cegueira legal nos estágios finais da doença.

MECANISMO DE DOENÇA

Bietti crystalline corneoretinal dystrophy

An autosomal recessive ocular disease characterized by retinal degeneration and marginal corneal dystrophy. Typical features include multiple glistening intraretinal crystals scattered over the fundus, a characteristic degeneration of the retina, and sclerosis of the choroidal vessels, ultimately resulting in progressive night blindness and constriction of the visual field. Most patients have similar crystals at the corneoscleral limbus. Patients develop decreased vision, nyctalopia, and paracentral scotomata between the 2nd and 4th decade of life. Later, they develop peripheral visual field loss and marked visual impairment, usually progressing to legal blindness by the 5th or 6th decade of life.

Exploration and Application of Multiluminance Mobility Test in Bietti Crystalline Dystrophy.

Translational vision science &amp; technology2026 Feb 02

This study evaluated the multiluminance mobility test (MLMT) as a functional vision assessment tool for Bietti crystalline dystrophy (BCD) and explored its relationship with structural and visual function parameters. A retrospective study of 34 BCD patients (67 eyes) incorporated 2 additional low light levels (0.1 and 0.5 lux) into the MLMT. Visual function assessments included best-corrected visual acuity, visual field (VF), and microperimetry (MP). Macular structure was evaluated via spectral-domain optical coherence tomography. MLMT performance was correlated with these parameters using Spearman's rank correlation tests. Despite severe global photoreceptor dysfunction, a notable proportion of participants (38.8%) passed the MLMT at 1 lux or less, with 23.9% reaching the lowest luminance (0.1 lux). MLMT lux scores correlated significantly with best-corrected visual acuity (ρ = -0.5322; P = 0.0012), mean defect of VF (ρ = -0.5919; P = 0.0005), and mean macular sensitivity of MP (MS-MP; ρ = 0.7175; P < 0.0001). Subgroup analysis revealed that subjects with preserved foveal ellipsoid zone had significantly higher MLMT lux scores and better MS-MP (both P < 0.05) than those with ellipsoid zone atrophy. Although visual function parameters were markedly impaired in certain patients, their MLMT performance remained relatively favorable. The standardized MLMT has a limited range for assessing advanced BCD. Preservation of central macular structure, rather than visual acuity alone, appears to be critical for mobility performance in BCD patients. Disease-specific adaptations of functional end points are needed for BCD clinical trials. To assess functional vision for BCD, the MLMT requires adaptation, and clinical trials should incorporate macular structural parameters.

Gene therapy for Bietti crystalline corneoretinal dystrophy: A phase 1/2 clinical trial.

Molecular therapy : the journal of the American Society of Gene Therapy2026 Mar 04

Bietti crystalline corneoretinal dystrophy (BCD) is an inherited retinal degeneration caused by bi-allelic variants in the CYP4V2 gene. Here, we report a phase 1/2, dose-escalation clinical study to assess the safety and efficacy of ZVS101e, an adeno-associated viral (AAV)-mediated gene-augmentation therapy (rAAV2/8-hCYP4V2), in 11 BCD patients with up to 365 days of follow-up (NCT05832684). ZVS101e showed a favorable safety profile, with no dose-limiting toxicities or drug-related serious adverse events. Inflammatory response was observed, primarily in the medium- and high-dose groups, which were effectively managed with corticosteroids. Efficacy was optimal in the low-dose group, with mean best-corrected visual acuity improvement of 14.0 letters and 50% of participants achieving clinically meaningful gains (≥15 letters). Functional assessments, including a multi-luminance mobility test and Visual Function Questionnaire-25, along with retinal structure, demonstrated consistent improvements. These results highlight ZVS101e's therapeutic potential for BCD, supporting further clinical development.

Compound heterozygous variants in CYP4V2 and LRTOMT coinciding in a single family: a rare case of combined Bietti crystalline dystrophy and nonsyndromic hearing loss.

Ophthalmic genetics2026 Mar 02

This study reports the rare co-occurrence of CYP4V2 (causing Bietti crystalline dystrophy, BCD) and LRTOMT (causing nonsyndromic hearing loss) variants within a single family and analyzes their clinical correlation. Exome sequencing was performed on three siblings with distinct clinical phenotypes. Sanger sequencing was used for variant confirmation. Although parental data was unavailable, the inheritance pattern was analyzed through co-segregation within the family. The proband, affected by both conditions, carried compound heterozygous variants in both CYP4V2 and LRTOMT genes. This correlated with more severe hearing loss compared to siblings carrying only LRTOMT variants. Siblings with isolated BCD or hearing loss carried variants only in the respective single gene. The findings suggest a double-compound heterozygous state in the proband. This case highlights the genetic complexity of multisensory disorders, where the co-inheritance of variants in distinct genes may lead to a more severe phenotype. It underscores the need for comprehensive genetic testing and counseling in affected families.

Intrascleral and Peripheral Retinal Crystals in Bietti Crystalline Dystrophy.

Retinal cases &amp; brief reports2026 Jan 15

To report a case of intrascleral crystal deposition in a patient with genetically confirmed Bietti Crystalline Dystrophy (BCD). Case report of a 51-year-old Asian male with high myopia, nyctalopia since early adulthood and progressive visual decline. Clinical examination, fundus photography, infrared reflectance, spectral-domain OCT, and ultra-widefield swept-source (SS) OCT were performed. Genetic testing was performed to evaluate for pathogenic mutations in CYP4V2 . Pseudocolor fundus photography revealed yellow-white crystalline deposits primarily in the posterior pole with poor visualization of crystals more peripherally. Cross-sectional OCT localized hyperreflective deposits predominantly at the retinal pigment epithelium-Bruch's membrane complex, with additional foci in the outer and inner retina, accompanied by chorioretinal atrophy. Intrascleral crystals were also identified on spectral domain OCT. Ultra-widefield OCT extended the assessment beyond the vascular arcades, revealing peripheral zones of atrophy and scattered crystals not visible on standard field scans. Intrascleral crystal distribution may aid in broadening the phenotypic spectrum of BCD, supporting more accurate diagnosis and contributing to the understanding of its pathophysiology. UWF and multimodal imaging provide complementary insights into BCD extent and crystal localization. Infrared reflectance outperforms pseudocolor photography for crystal detection, while UWF-OCT expands structural evaluation into the periphery, potentially improving monitoring strategies.

The role of full-field stimulus threshold in evaluating Bietti crystalline dystrophy.

Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie2026 Mar

Visual functional testing methods are limited and cannot be well applied in all kinds of ocular diseases, especially those with low-vision. To determine whether full-field stimulus threshold (FST) is an effective method in evaluating Bietti crystalline dystrophy (BCD), with the capability in replacing other traditional visual functional methods, we designed the study. This study was a prospective cross-sectional observational study, conducted from September 2022 to March 2023. It was a sub-study of Beijing Tongren Eye Disease Clinical Database Biobank. The study was conducted in Beijing Tongren Hospital, Capital Medical University. BCD patients who were diagnosed based on clinical features, validated by whole-exome sequencing were included. The normal volunteers were included as control group. All BCD patients underwent comprehensive evaluations, including FST, best-corrected visual acuity (BCVA), color vision, microperimetry, full-field electroretinography (ffERG), optical coherence tomography (OCT), multimodal imaging system and 4 self-reported questionnaires. The normal control group subjects only conducted FST examination. The correlation between FST and BCVA, and the differences of FST values between disease severity groups, were evaluated. The BCVA logistic regression model, FST model and hybrid model's performance (area under the curve [AUC]) were tested in predicting disease severity. 43 BCD patients (40.60 ± 8.57 years, 22 female [51%]) and 36 normal volunteers (38.56 ± 12.42 years, 21 female [58%]) were included. FST showed a moderate correlation with BCVA scores. Stage 2 group exhibited notably lower FST values than the stage 3 group, while the severely diminished group showed remarkable lower FST values than the extinguished group. The hybrid model showed better performance (AUC = 0.9221 and 0.9496) than FST model (AUC = 0.9026 and 0.9429), better than BCVA model (AUC = 0.8549 and 0.8487) in predicting disease severity. The FST serves as a useful indicator for evaluating visual function and predicting the severity of disease in patients with BCD. The clinical implementation of FST value will serve as an important assay in various ocular diseases, necessitating further validation studies prior to its application.
