✦ Synopsis
A 47-year-old patient was legally blind in her only eye for months due to long-lasting ocular hypotension following chronic uveitis and several operations for cataract and secondary glaucoma. With injections of 0.7 to 2.5 cc 1% Healon | into the anterior chamber and vitreous cavity at intervals of 2 to 12 months, intraocular pressure levels between 5 and 12 mmHg could be maintained resulting in an improvement of the visual acuity up to 25/100. The treatment has been continued for over 5 years. A positive correlation was found between the volume of injected Healon | and the integral of intraocular pressure over time, and between visual acuity and pressure level. Reduced aqueous flow, high trabecular outflow resistance, and a low rate of clearance of Healon | from the vitreous cavity is obviously responsible for the long-lasting elevation of low intraocular pressure levels and for the restoration of useful vision.
