The pars plana approach in two cases of persistent hyperplastic primary vitreous (PHPV)
Ophthalmic Paediatrics and Genetics
|August 1, 1984
Summary
This study details two successful surgeries for persistent hyperplastic primary vitreous using the pars plana approach. The described surgical technique proved both safe and effective for treating this congenital eye condition.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Persistent hyperplastic primary vitreous (PHPV) is a rare congenital developmental anomaly of the eye.
- It can lead to significant visual impairment if not managed appropriately.
Observation:
- Two pediatric cases of PHPV were treated.
- The surgical intervention involved the pars plana approach.
Findings:
- The pars plana approach was utilized for the surgical management of PHPV.
- The technique demonstrated safety and efficacy in both reported cases.
Implications:
- The pars plana approach offers a viable surgical option for persistent hyperplastic primary vitreous.
- Further studies may validate this technique in a larger patient cohort.

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...
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...
