Summary
Thalidomide exposure between days 20-26 post-fertilization is linked to Duane syndrome and other facial anomalies. This research clarifies the teratogenic timetable for thalidomide, aiding in understanding developmental abnormalities.
Area of Science:
- Teratology
- Developmental Biology
- Ophthalmology
Background:
- The thalidomide tragedy highlighted the critical importance of drug safety during pregnancy.
- A teratogenic timetable was established, linking specific developmental abnormalities to exposure timing.
Purpose of the Study:
- To summarize ophthalmologic findings related to thalidomide exposure.
- To correlate ocular anomalies with the timing of teratogenic exposure.
Main Methods:
- Review of existing studies on thalidomide exposure and resulting birth defects.
- Analysis of ophthalmologic findings in conjunction with other malformations.
- Comparison of anomaly timing with established teratogenic periods.
Main Results:
- Early thalidomide exposure (days 20-26) is strongly associated with Duane syndrome and variants.
- Aberrant tearing, facial nerve palsy, ear malformations, and autism were also linked to early exposure.
- Structural eye malformations occurred less frequently and appeared later in the sensitive period.
Conclusions:
- Ophthalmologic findings, when correlated with well-documented external ear and limb malformations, provide insights into thalidomide exposure timing.
- Understanding the temporal relationship between thalidomide exposure and specific anomalies is crucial for diagnosis and prevention.

01:25Drug Regulation
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
