Scleral trephination for subchoroidal effusion.

Archives of Ophthalmology (Chicago, Ill. : 1960)

|December 1, 1983

Summary

Posterior scleral trephination is a reliable method for draining subchoroidal effusions, especially after eye surgery or hemorrhage. This technique offers sustained drainage, unlike linear sclerotomy.

Area of Science:

Ophthalmology
Surgical Techniques
Retinal Diseases

Background:

Flat anterior chamber is a serious complication following ocular surgery.
Subchoroidal effusions can lead to a flat anterior chamber, potentially causing vision loss.
Existing methods for effusion drainage have limitations.

Observation:

Posterior scleral trephination was performed at the pars plana ciliaris in a dependent site.
The conjunctiva covered the trephination opening, maintaining ocular integrity.
This technique was applied to cases with flat anterior chamber, post-retinal detachment surgery, and expulsive hemorrhage.

Findings:

Posterior scleral trephination proved to be a reliable method for evacuating subchoroidal effusions.
The procedure was successful in various clinical scenarios, including post-surgical complications and expulsive hemorrhage.
Continuous drainage of subchoroidal fluid occurred over several days, exceeding the duration of linear sclerotomy.

Implications:

This technique offers a reliable and effective solution for managing subchoroidal effusions and associated complications.
The sustained drainage may improve outcomes in patients with flat anterior chambers.
Posterior scleral trephination presents a valuable alternative to traditional sclerotomy methods in specific ophthalmic situations.
