A 74-year-old male patient consulted for recurrent episodes of painful red eye in the inner eye, associated with progressive loss of vision over several months. He reported no relevant systemic personal history. His ophthalmic history included accidental exposure to a cleaning product 15 years earlier.
Ophthalmological examination showed visual acuity (VA) of 8/10 in the right eye (RA) and 1/10 in the left eye (LO). The biomicroscopic examination revealed an area of approximately 210º of corneal conjunctivalisation affecting the visual axis, with superficial vascularisation and mixed hyperemia. There was a sector of limbus of approximately 5 hours extension that preserved the normal architecture of Vogt's palisades and an absence of dye staining. The rest of the examination showed no relevant findings.

With the clinical diagnosis of partial IL with visual axis involvement, an ECS of the fibrovascular tissue invading the corneal surface was performed, including the affected limbar area, and respecting the sector of the nasal limbus with normal characteristics. An amniotic membrane (AM) graft was placed in the denuded area and sutured with the epithelium facing upwards and then another 15 mm diameter circular fragment of AM was sutured as a patch, with the epithelium facing downwards. During follow-up there was progressive re-epithelialisation with a corneal-like epithelium over the MA graft which was integrated under the MA graft. At 3 weeks after surgery there was a smooth and regular corneal epithelial surface and a significant reduction of the associated mixed hyperemia. The VA of the OI improved to 4/10. With a follow-up of 8 months no recurrences have been observed.
