OBJECTIVES: To evaluate the clinical characteristics and treatment strategies of limbal stem cell deficiency (LSCD) patients managed with medical therapy.
MATERIALS AND METHODS: The study included 29 eyes of 21 patients with LSCD who were managed medically at Ege University Faculty of Medicine, Department of Ophthalmology between May 2013 and May 2023. LSCD stages before and after medical treatment were recorded according to the LSCD staging system published by the International LSCD Working Group. The medical records of patients showing improvement in LSCD stage with medical treatment without surgical intervention were evaluated.
RESULTS: The mean age was 35.5±23.8 years (range, 5-71 years) with a male-to-female ratio of 6:15. The primary etiology of LSCD was ocular rosacea in 12 patients (57.1%), marginal keratitis in the setting of blepharitis in 8 patients (38.1%), and topical medication toxicity in 1 patient (4.8%). The mean baseline best corrected visual acuity (BCVA) was 0.25±0.26 logarithm of the minimum angle of resolution (logMAR) (range, 0-1 logMAR). Pre-treatment LSCD stage was stage 1A in 5 eyes (17.2%), stage 1B in 12 eyes (41.4%), stage 1C in 4 eyes (13.8%), stage 2A in 4 eyes (13.8%), and stage 2B in 4 eyes (13.8%). Complete regression of LSCD was achieved in 6 eyes (20.7%) with medical treatment addressing the primary etiology. In the remaining eyes, after medical treatment, the severity of LSCD decreased below the surgical threshold, which is considered stage 2B. The mean final BCVA was 0.07±0.1 logMAR (range, 0-0.4 logMAR).
CONCLUSION: This study highlights that LSCD can be completely or partially reversible with appropriate management, especially in cases with underlying limbal niche dysfunction, where inflammation plays a significant role. Although limbal stem cell transplantation is considered the main treatment approach for LSCD, localized and early-stage LSCD can be effectively managed medically without the need for surgical intervention.
