The procedure described by CPT® Code 0176T involves the transluminal dilation of the aqueous outflow canal, specifically Schlemm's canal, without the retention of any device or stent. This intervention is primarily indicated for the treatment of open-angle glaucoma, a condition characterized by increased intraocular pressure (IOP) that can lead to optic nerve damage and vision loss. The procedure, often referred to as glaucoma canaloplasty or enhanced viscocanalostomy, aims to restore the natural drainage of aqueous humor from the eye, thereby reducing IOP. During the procedure, a scleral flap is created to access the canal, which is then deroofed to expose its interior. A flexible microcatheter or cannula is introduced into the canal, allowing for the instillation of a viscoelastic substance, such as high viscosity sodium hyaluronate, to facilitate dilation. This process enhances the canal's capacity to drain fluid effectively. The procedure concludes with the withdrawal of the cannula and closure of the scleral flap, ensuring that the canal remains open for improved fluid drainage without the need for a stent or device retention.

The procedure described by CPT® Code 0176T is indicated for the treatment of open-angle glaucoma, a condition that results in increased intraocular pressure (IOP) and can lead to significant vision impairment if left untreated. The primary goal of this procedure is to reduce IOP by enhancing the drainage of aqueous humor through Schlemm's canal, thereby alleviating the symptoms and complications associated with glaucoma.
The procedure involves several key steps to ensure effective dilation of the aqueous outflow canal.
Post-procedure care following the transluminal dilation of the aqueous outflow canal typically involves monitoring the patient's intraocular pressure and assessing for any complications. Patients may be advised to follow up with their ophthalmologist to ensure proper healing and to evaluate the effectiveness of the procedure in reducing IOP. Additional considerations may include the use of prescribed medications to manage inflammation or discomfort, as well as instructions on activity restrictions to promote optimal recovery.
