Summary
Ophthalmological examination of individuals with thalidomide embryopathy revealed that eye abnormalities are common, affecting 54%. Ocular motility defects, facial palsy, and abnormal lacrimation suggest thalidomide
Area of Science:
- Ophthalmology
- Teratology
- Genetics
Background:
- Thalidomide embryopathy is a congenital condition with diverse manifestations.
- Ocular involvement in thalidomide embryopathy is recognized but requires detailed characterization.
Purpose of the Study:
- To prospectively evaluate the spectrum and frequency of ocular abnormalities in Swedish individuals with thalidomide embryopathy.
- To correlate ocular findings with the timing of thalidomide exposure during gestation.
Main Methods:
- Prospective ophthalmological study of 86 individuals with established thalidomide embryopathy.
- Systematic recording of ocular findings, including motility, cranial nerve palsies, and structural anomalies.
Main Results:
- 54% of individuals exhibited eye findings, making the eye the second most affected organ.
- Ocular motility defects (50%), facial palsy (20%), and abnormal lacrimation (20%) were most common.
- Specific anomalies included strabismus, coloboma, microphthalmos, glaucoma, and refractive errors.
Conclusions:
- Ocular structures are frequently affected in thalidomide embryopathy.
- The occurrence of ocular motility defects, facial palsy, and abnormal lacrimation suggests early developmental disruption, likely around the fourth week of gestation.
