# Dystrophia Adiposa Corneae: An Out-of-the-Box Diagnosis

## TL;DR

This paper reports a rare corneal condition called dystrophia adiposa corneae in a 40-year-old Indian man, emphasizing the importance of recognizing this vision-threatening disorder.

## Contribution

The paper presents a rare clinical case of dystrophia adiposa corneae with detailed diagnostic findings and highlights its distinct features.

## Key findings

- Bilateral peripheral lipid deposition in the corneal stroma was observed, progressing to an annular shape.
- Cholesterol crystals and crystalline structures were identified without neovascularization.
- The patient had mild dyslipidaemia, linking systemic lipid issues to the corneal pathology.

## Abstract

Dystrophia adiposa corneae is a degenerative corneal disorder characterised by fatty deposition, leading to corneal opacity and reduced visual acuity. We report a case of an Indian male in his early 40s with bilateral peripheral deep lipid deposition in the corneal stroma, beginning in an arcuate fashion and progressing to an annular-shaped structure. Furthermore, cholesterol crystals, as well as crystalline structures, were seen without any neovascularisation. We confirmed these findings on anterior segment optical coherence tomography (AS-OCT). We also noticed an increase in central corneal thickness (CCT), and on systemic workup, the patient was diagnosed with mild dyslipidaemia. This case highlights the need for an out-of-the-box diagnosis of a rare keratopathy, which can be vision-threatening and needs to be differentiated from its mimickers.
