Tear of Retinal Pigment Epithelium following YAG Laser Posterior Capsulotomy in a Patient on Anti-VEGF Treatment for AMD: Six Months’ Follow-Up

PURPOSE To present a rare case of retinal pigment epithelium (RPE) rupture following YAG laser posterior capsulotomy (YAG PC) in a patient with exudative age-related macular degeneration (AMD). MATERIALS AND METHODS An 85-year-old pseudophakic male patient on ranibizumab 0.5 mg/0.05 ml treatment due to exudative AMD received YAG PC for dense posterior capsule opacification (PCO) in his right eye. The patient had received his last intravitreal ranibizumab injection 3 months before YAG PC; his macula appeared stable on fundoscopy and optical coherence tomography scans at repeated visits, but his vision deteriorated to counting fingers due to PCO. RESULTS Following left eye posterior YAG PC, his best-corrected visual acuity (BCVA) improved to 6/12 (Snellen chart). Despite satisfactory visual results, the patient developed a parafoveal inferotemporal RPE rupture. A decision for further treatment with ranibizumab (0.5 mg/0.05 ml) intravitreal injections was made. After a total of 7 injections, the patient was clinically stable and his BCVA was 6/18 (Snellen chart). CONCLUSIONS RPE rupture is a well-known, serious complication in patients with exudative AMD, which often has devastating results on patients' vision. Offering YAG PC to those patients could lead to a rupture of the RPE even in cases which appear to be stable and well controlled. Clinicians should be aware of this complication and inform the patients accordingly.
