## TL;DR

This case report describes a rare instance of optic disc pseudoduplication caused by laser treatment for diabetic macular edema.

## Contribution

The paper presents a novel case linking optic disc pseudoduplication to a laser-induced choroidal neovascular membrane.

## Key findings

- Optic disc pseudoduplication can occur as a result of laser-induced choroidal neovascular membrane.
- The condition may present with an optic disc-like lesion adjacent to the true optic nerve head.
- This case highlights an unusual cause of optic disc pseudoduplication unrelated to coloboma.

## Abstract

Optic disc pseudoduplication, or pseudo-doubling, is a rare clinical condition that refers to the presence of an optic disc-like lesion located adjacent to the true optic nerve head, creating the impression of a duplicated disc. The vast majority of reported cases are associated with optic disc or chorioretinal coloboma. In this article, we present a rare example of pseudo-disc formation that developed secondary to a laser-induced choroidal neovascular membrane, highlighting its unusual appearance.
