2

Visual Field Testing and OCT RNFL Assessment

Comprehensive structural and functional evaluation of the retinal nerve fiber layer through automated perimetry and repeat OCT measurements. Baseline documentation enables detection of progressive thinning indicative of glaucomatous or neurodegenerative processes.

monitoring
3

Intraocular Pressure Reduction Therapy

Topical medication regimen to lower intraocular pressure when elevated tension contributes to RNFL damage. Multiple agent classes may be employed to achieve target pressures individualized to the patient's optic nerve status.

Additional treatment options

Glaucoma Filtration Surgery

Surgical creation of an alternative outflow pathway for aqueous humor through trabeculectomy or implantation of drainage devices. Reserved for cases where medical therapy fails to adequately control progression.

surgical

Selective Laser Trabeculoplasty

Minimally invasive laser procedure targeting trabecular meshwork cells to enhance aqueous outflow. Offers an alternative or adjunct to topical medication for achieving target intraocular pressure.

Blood Pressure and Systemic Vascular Health Management

Coordination with primary care to optimize systemic blood pressure control and cardiovascular risk factors. Research suggests vascular dysregulation contributes to RNFL thinning in some patients.
