Retinal pigment epithelial rip during krypton red laser photocoagulation

Area of Science:

• Ophthalmology
• Retinal Diseases
• Neovascularization

Background:

• Choroidal neovascularization (CNV) is a leading cause of vision loss in age-related macular degeneration.
• Treatment options for CNV include photocoagulation, anti-VEGF therapy, and surgery.
• Photocoagulation, particularly with krypton red laser, has been used to treat specific types of CNV.

Observation:

• Three patients (two female, 73-74 years; one male, 74 years) underwent krypton red photocoagulation for CNV.
• A pigment epithelial rip was observed near the edge of a hypopigmented, partly organized CNV in all three patients during treatment.
• The rips occurred specifically at the time of photocoagulation application.

Findings:

• Pigment epithelial rips are a potential complication of krypton red photocoagulation for CNV.
• The rips were located adjacent to the treated CNV, suggesting a direct relationship with the laser application.
• All three patients experienced a significant decrease in visual acuity, with a final acuity of 20/200.

Implications:

• Krypton red photocoagulation may pose a risk of iatrogenic pigment epithelial rips.
• This complication can lead to severe visual impairment, emphasizing the need for careful treatment planning.
• Ophthalmologists should be aware of this risk when considering krypton red laser treatment for CNV.
