Insights

Primary congenital glaucoma (PCG) can spontaneously resolve in some children. Ocular findings in these cases include large corneas and abnormal angles, with normal intraocular pressures.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Glaucoma Research

Background:

  • Primary congenital glaucoma (PCG) is a severe form of infantile glaucoma.
  • Spontaneous resolution of PCG is a rare phenomenon.
  • Understanding its characteristics is crucial for diagnosis and management.

Purpose of the Study:

  • To document the ocular characteristics of children experiencing spontaneous resolution of PCG.
  • To differentiate findings in spontaneously resolving PCG from treated or untreated cases.

Main Methods:

  • Retrospective review of 356 PCG patient records.
  • Detailed analysis of nine cases with documented spontaneous PCG resolution.
  • Clinical examination of ocular findings, including corneal diameter, Haab's striae, intraocular pressure, anterior chamber depth, lens clarity, and angle morphology.

Main Results:

  • Spontaneous resolution was observed in nine patients, typically after four months of age.
  • Affected eyes presented with large corneas and Haab's striae.
  • Intraocular pressures were normal, with deep anterior chambers and abnormal filtration angles characteristic of PCG.
  • Angle abnormalities were less severe than in fellow eyes requiring treatment.

Conclusions:

  • Objective clinical evidence supports spontaneous PCG resolution.
  • The exact mechanism remains unknown but may involve continued development of milder angle abnormalities.
  • Anterior segment findings resemble treated PCG, but with normal intraocular pressures and stable optic nerves.

Glaucoma: 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...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
