Microphthalmia, also known as microphthalmos, refers to a congenital eye condition characterized by abnormally small eyes. It is a rare condition that can occur in isolation or as part of a larger syndrome. The term "microphthalmia" is derived from the Greek words "mikros" meaning small and "ophthalmos" meaning eye.
Individuals with microphthalmia typically have eyes that are smaller than the average size for their age and gender. The condition can affect one or both eyes, and the severity can vary. In some cases, the eyes may appear normal but have reduced visual acuity, while in others, the eyes may be visibly small and have additional structural abnormalities.
Microphthalmia can be associated with various genetic and environmental factors. It may occur as an isolated condition or be part of a genetic syndrome, such as anophthalmia/microphthalmia syndrome, coloboma, or chromosomal abnormalities. The condition can also be caused by exposure to certain drugs, infections, or toxins during pregnancy.
Synonyms for microphthalmia include microphthalmos, small eye syndrome, and nanophthalmos. These terms are often used interchangeably to describe the same condition. It is important to note that microphthalmia should not be confused with anophthalmia, which refers to the absence of one or both eyes.
Diagnosis of microphthalmia is typically made through a comprehensive eye examination, including measurements of eye size, visual acuity testing, and imaging studies. Genetic testing may also be recommended to identify any underlying genetic abnormalities.
Treatment for microphthalmia depends on the individual case and associated complications. It may involve corrective eyewear, low vision aids, or surgical interventions to improve visual function or address structural abnormalities. Early intervention and ongoing monitoring are crucial to optimize visual outcomes and manage any associated conditions.
