Recommendations
Diagnosis
Optical Coherence Tomography
Spectral domain OCT is a highly sensitive and routine method used to diagnose and characterize VMA, ERM, VMT, and the associated retinal changes.
569
Discussion with Patient
Patients should be informed that the majority of ERMs will remain relatively stable and do not require therapy.
569
Patients should also be reassured that there is a very successful surgical procedure that could address worsening symptoms or decreasing visual acuity.
569
Furthermore, patients should be encouraged to periodically test their central vision monocularly in order to detect changes that may occur over time, such as increasing metamorphopsia and/or development of a small, central scotoma.
569
Educating patients about the signs and symptoms of progression and regular monocular Amsler grid testing are both important. Although the visual acuity rarely improves spontaneously, it may worsen. If patients' symptoms worsen, a vitrectomy could be considered. Patients do not typically improve without vitrectomy surgery when the area of VMT is broad (>1500 μm), when there is an accompanying pathologic detachment of the macula, or when the presenting visual acuity is poor.
569
Appropriate intervention should be made with careful informed consent and a discussion of the risk-benefit ratio of surgery.
569
Treatment
Vitreopharmacolysis – Ocriplasmin
The treating physician should discuss the option of treating patients who have VMT with ocriplasmin and compare the treatment with observation, a gas bubble injected into the vitreous, or vitrectomy surgery.
569
The discussion should include the relevant risks versus benefits for each of these options.
569
Outcome
Vitrectomy surgery is often indicated in patients who are affected with a decrease in visual acuity, metamorphopsia, double vision, or difficulty using their eyes together.
569
Predictors Of Visual Results After Surgery
The outer retina, the ellipsoid zone (EZ), and the photoreceptors' outer segment length may improve or even normalize after vitrectomy, and each feature is correlated with improved visual acuity.
569
Follow-Up Evaluation After Surgery
Patients who have surgery should be examined on postoperative day 1 and again 1–2 weeks following surgery or sooner, depending upon the development of new symptoms or new findings during early postoperative examination.
569
Provider and Setting
Diagnosis and management of ERM, VMT, or VMA requires special expertise, surgical skills, and specialized equipment to detect alterations in the retina in order to select, perform, implement, and monitor appropriate management or treatment.
569
Counseling and Referral
Patients should be informed to notify their ophthalmologist promptly if they have symptoms such as an increase in floaters, a loss of visual field, metamorphopsia, or a decrease in visual acuity.
