Buphthalmos, also known as congenital glaucoma, is likely the diagnosis for a one-month-old infant presenting with excessive tearing and enlarged cornea.
Explanation:
- Infants with buphthalmos show signs of increased intraocular pressure, causing the eye to enlarge, known as megalocornea or corneal enlargement.
- Common symptoms include excessive tearing (epiphora) due to the build-up of fluid in the eye.
- Other options like Hurlers Syndrome, Galactosemia, and Cataract have different presentations. For instance, cataract usually leads to cloudy vision rather than watering and corneal enlargement.
Thus, given the symptoms of watering and increased corneal size, Buphthalmos is the accurate diagnosis.
