Purpose: We demonstrate a novel approach for the definitive treatment of Lisch epithelial corneal dystrophy via an unintentionally staged alcohol keratectomy and intentionally targeted minor limbal excision with cautery.
Methods: A 46-year-old woman presented with visually significant corneal changes, suspected to be Lisch epithelial corneal dystrophy after clinical examination, anterior segment optical coherence tomography, and confocal microscopy. Alcohol keratectomy was performed with complete resolution, but there was visually significant recurrence at 2 years. As the abnormal epithelial recurrence originated in a linear tapered pattern from a focal superior limbal region, minor limbal excision with cautery and alcohol keratectomy was performed.
Results: Histopathological analysis demonstrated cytoplasmic vacuolation and glycogen granules. The limbal tissue demonstrated normal histological features. The patient's vision returned to baseline on reepithelialization with a clear cornea, with no recurrence in over 5-year follow-up.
Conclusions: Our targeted two-staged approach provides definitive treatment for Lisch epithelial corneal dystrophy and highlights the focal limbal origin of abnormal cells.

Anterior segment swept-source optical coherence tomography and ultrasound biomicroscopy in iris and ciliary body lesions.

Article Synopsis
- The study aimed to differentiate between benign and malignant eye lesions in the iris and ciliary body by comparing two imaging techniques: anterior segment swept-source optical coherence tomography (AS SS-OCT) and ultrasound biomicroscopy (UBM).
- A retrospective evaluation of 42 eyes revealed various tumor types, with both imaging methods providing 100% visualization of the anterior tumor margin, but UBM being better for posterior margin visualization in certain types of tumors.
- The findings suggest that while UBM is the preferred method for imaging these tumors, AS SS-OCT is a viable alternative, especially for less prominent iris lesions.

Department of Ophthalmology, Johannes Gutenberg University Mainz, Mainz, Germany.
Purpose: The International Committee for the Classification of Corneal Dystrophies (IC3D) was created in 2005 to develop a new classification system integrating current information on phenotype, histopathology, and genetic analysis. This update is the third edition of the IC3D nomenclature.
Methods: Peer-reviewed publications from 2014 to 2023 were evaluated.
Lisch Epithelial Corneal Dystrophy Is Caused by Heterozygous Loss-of-Function Variants in MCOLN1.

Article Synopsis
- The study investigates the genetic causes of Lisch epithelial corneal dystrophy (LECD) through a multicenter cohort involving 27 individuals from 17 families.
- Researchers found nine rare variants of the MCOLN1 gene in 23 patients, indicating that mutations in this gene lead to LECD and potentially other conditions like mucolipidosis IV (MLIV).
- The findings suggest that while MCOLN1 haploinsufficiency is the main contributor to LECD, there is variability in how strongly the condition manifests, highlighting a complex relationship between genetics and disease expression.
