Interpretation of Findings and Development of Management Plans

Domain focus

Interpretation of findings and development of management plans tests integration: you must read visual fields, optic nerve imaging, fundus findings, and laboratory values together, stage disease, set a target, and choose monitoring intervals. TMOD emphasizes glaucoma, diabetic retinopathy, macular degeneration, and uveitis.

Core rules

  • Confirm before staging: glaucomatous field loss must be repeatable and compatible with disc damage; OCT RNFL thinning should match the field defect.
  • Use risk factors to set target IOP: thinner central cornea, disc hemorrhage, family history, and older age lower the target; a common goal is 20–30% reduction from baseline.
  • Stage diabetic retinopathy with the ETDRS severity scale; for diabetic macular edema, OCT central subfield thickness guides anti-VEGF therapy. For dry AMD, AREDS2 supplements are for intermediate disease; anti-VEGF is for exudative disease.
  • A management plan must include treatment, follow-up interval, referral threshold, and patient education.

Worked example

A 62-year-old with IOP 26/24 mmHg, CCT 505 µm, and a disc hemorrhage in the right eye has OCT RNFL thinning inferiorly and a repeatable superior arcuate defect on 24-2 VF. Reasoning: the triad of thin cornea, disc hemorrhage, and matching structure-function damage makes this glaucoma, not a suspect. Plan: start a prostaglandin analog once nightly in both eyes (or the affected eye if monocular), set target IOP ≤18 mmHg (≥30% reduction), repeat VF and OCT in 3–4 months, and counsel on adherence and nocturnal IOP. If IOP remains above target or field loss progresses, add a second agent or refer for laser trabeculoplasty.

Traps

  • Staging glaucoma from one unreliable field or one OCT printout without repeatability.
  • Treating diabetic macular edema with focal laser before anti-VEGF when the fovea is involved.
  • Calling a disc hemorrhage “artifact” without comparing it to RNFL and field data.
  • Writing a plan without a follow-up interval or a clear referral trigger.
