Advanced Diagnostic Eye Testing

State-of-the-art diagnostic imaging and testing for AMD, diabetic retinopathy, glaucoma, and high-risk medication monitoring. Detect disease before vision loss.

Early Detection

Why Diagnostic Testing Saves Vision

Most sight-threatening eye diseases are silent—they cause no symptoms until significant, irreversible damage has occurred. Advanced diagnostic testing detects cellular changes years before vision loss, enabling treatment when it matters most.

Structural Imaging

OCT reveals microscopic changes in retina layers invisible to standard exams

Functional Testing

ERG detects cellular dysfunction before structural damage appears

Visual Fields

Maps peripheral vision loss from glaucoma and neurological conditions

Medical Conditions

Our Technology

State-of-the-Art Diagnostic Equipment

OCT Imaging

Optical Coherence Tomography creates microscopic cross-sections of the retina and optic nerve. Essential for AMD, diabetic eye disease, and glaucoma monitoring.

10-micron resolution, 3D volumetric scans

ERG/VEP Testing

Electroretinography measures retinal cell electrical activity. LKC Technologies equipment detects dysfunction before visible damage.

Full-field, pattern, and multifocal ERG

Visual Field Analyzer

Humphrey Field Analyzer maps peripheral vision loss from glaucoma, strokes, and brain lesions with clinical precision.

24-2, 10-2, and kinetic protocols

Fundus Photography

High-resolution retinal imaging documents disease progression and enables telemedicine consultations with specialists.

45° to ultra-widefield imaging

Pentacam Tomography

3D corneal imaging for keratoconus screening, LASIK evaluation, and precision contact lens fitting.

25,000 data points per scan

Tonometry & Pachymetry

Accurate intraocular pressure measurement and corneal thickness analysis for glaucoma risk assessment.

Goldman, iCare, and ultrasonic

Risk Assessment

Who Should Have Diagnostic Testing?

High-Risk Patients

  • All diabetics — Annual dilated exam + OCT
  • Family history of glaucoma — Baseline visual fields + OCT
  • Plaquenil users — Annual OCT + visual field + mfERG
  • Family history of AMD — Baseline retinal imaging
  • High myopia (>6 diopters) — Peripheral retinal exam

Preventive Screening

  • Age 40+ — Baseline glaucoma screening
  • Age 55+ — AMD risk assessment
  • Unexplained vision changes — Comprehensive workup
  • New floaters/flashes — Urgent retinal evaluation
  • African American heritage — Earlier glaucoma screening (age 35)

Insurance Coverage for Diagnostic Testing

Medically necessary diagnostic testing is covered by most medical insurance plans and Medicare when ordered for specific ICD-10 coded conditions. Our staff verifies coverage before testing and handles all insurance billing.

Medicare

Covers OCT, visual fields, ERG for documented medical conditions

PPO Insurance

Most PPO plans cover diagnostic testing with medical necessity

HMO Plans

May require referral from PCP; we assist with authorization
