Treatment

Medical Care

In low-tension glaucoma (LTG), the aim of IOP-lowering medications is for a reduction of at least 30%.

Also see the following clinical guideline summaries:

Surgical Care

Argon laser trabeculoplasty (ALT): This procedure may have minimal effect because the intraocular pressure (IOP) is already in the reference range.

Selective laser trabeculoplasty (SLT): SLT targets pigment-producing cells in the trabecular meshwork with less tissue destruction and scarring compared with ALT.

Trabeculectomy: If medical therapy is ineffective, adjunctive antimetabolite therapy likely is needed for postoperative IOP to be in the single digits. A higher risk of hypotony and endophthalmitis exists when targeting extremely low pressures that may be needed to retard or prevent progression of field loss.

Consultations

Neurophthalmologist consultation can be ordered to rule out compressive optic neuropathy (as indicated).

Diet

An increase in salt intake may be recommended if the patient's diastolic blood pressure is significantly lower than the systolic blood pressure (ie, >70 mm Hg). However, controversy exists regarding this recommendation. Exercise caution in those patients with vascular or cardiac disease.
