A Hidden Case of Occult Macular Neovascularization
A 68-year-old presented with blurry vision bilaterally and was diagnosed with a nonexudative occult neovascular membrane; further evaluation and referral to a specialist were recommended. Authored by Dr. Julie Rodman, OD, MSc, FAAO, a celebrated optometrist specialized in retinal disease.
Clinical Scorecard: A Hidden Case of Occult Macular Neovascularization
At a Glance
Category
Detail
Condition
Nonexudative occult macular neovascularization
Key Mechanisms
Presence of flat occult choroidal neovascular membrane without active exudation or leakage; detected by OCT and OCT angiography showing increased flow in choriocapillaris slab
Target Population
Older adults presenting with subtle visual symptoms and drusen, including those with normal visual acuity
Care Setting
Primary eye care with referral to retina specialist for further evaluation and monitoring
Key Highlights
Occult macular neovascular membranes may be asymptomatic and lack active exudation or leakage.
Multimodal imaging, especially OCT and OCT angiography, is essential for detection and monitoring.
Close monitoring is necessary to detect progression to exudative disease requiring treatment.
Guideline-Based Recommendations
Diagnosis
Perform comprehensive eye examination including slit lamp biomicroscopy and dilated fundus exam.
Use multimodal imaging with OCT and OCT angiography to identify occult neovascular membranes and assess flow characteristics.
Management
Refer patients with occult macular neovascularization to retina specialists for evaluation.
Monitor closely for signs of progression to exudative disease.
Monitoring & Follow-up
Regular follow-up with OCT and OCT angiography to detect any development of exudation or leakage.
Assess visual acuity and symptoms at each visit.
Risks
Potential progression from nonexudative to exudative macular neovascularization leading to vision loss.
Patient & Prescribing Data
Older adults with occult macular neovascularization detected on imaging without active exudation.
No immediate treatment indicated for nonexudative lesions; emphasis on monitoring and timely intervention upon progression.
Clinical Best Practices
Utilize OCT angiography to detect neovascular flow in the choriocapillaris slab for early diagnosis.
Educate patients about the importance of regular monitoring despite absence of symptoms.
Coordinate care with retina specialists for comprehensive management.
I need to know that the patients I schedule have a high probability of a successful outcome. I define “successful” as the patient says they benefit, and I earn a fee commensurate with my knowledge and experience.
