Presumed choroidal naevi and sensory retinal detachment

Area of Science:

• Ophthalmology
• Medical Imaging
• Oncology

Background:

• Choroidal nevi can present with visual disturbances.
• Abnormal retinal pigment epithelium (RPE) overlying choroidal lesions requires investigation.

Observation:

• Two patients experienced blurred central vision secondary to choroidal nevi.
• Fluoroangiography revealed sensory retinal elevation above the pigmented lesions.
• Morphologically altered RPE, including lipofuscin, was noted overlying the tumors.

Findings:

• Low-intensity argon laser photocoagulation successfully treated both cases.
• Patients achieved a return of central vision without complications.
• Photographic documentation confirmed outcomes over a significant follow-up period.

Implications:

• Argon laser photocoagulation is an effective treatment for visual disturbances caused by choroidal nevi.
• Identifying altered RPE, especially lipofuscin, is crucial for diagnosing choroidal tumors.
• Early diagnosis and treatment can prevent vision loss from choroidal lesions.
