Introduction:
The management of large pigment epithelial detachments (PEDs) associated with retinal angiomatous proliferation (RAP) remains a challenge due to the high risk of retinal pigment epithelial (RPE) tear. We describe the successful progressive anatomical result and the maintenance of visual acuity to bimonthly, half-dose ranibizumab in a patient with this condition.
Purpose:
To describe the management of a large PED secondary to RAP with bimonthly, half-dose ranibizumab.
Method:
Case report.
Patient:
A 71-year-old woman presented with visual symptoms due to an enlarged PED, compared with previous visits, secondary to a RAP lesion, with a visual acuity of 20/32. To reduce the risk of an RPE tear and a significant decrease in vision, we discussed with the patient the possibility of treating the lesion in a progressive manner, with more frequent but smaller doses of ranibizumab. The patient was treated biweekly with 0.25 mg of ranibizumab until fattening of the PED.
Results:
The large PED fattened progressively, and visual acuity was preserved with no adverse events.
Discussion:
The use of half-dose antiangiogenic therapy may be useful in managing large vascularized PED associated with RAP, in an attempt to reduce the risk of RPE tear.
