Purpose: To study the outcomes of topical Retinol Palmitate ophthalmic solution in chronic Stevens-Johnson Syndrome with ocular surface keratinisation.
Methods: It was a comparative interventional study conducted at Rajendra Prasad Centre for Ophthalmic Sciences, Delhi, India from 2020 to 2022 evaluating outcomes of addition of topical Retinol Palmitate to conventional treatment objectively as well as subjectively from baseline up to 12 weeks.
Results: A statistically significant improvement was seen in patients who received topical Retinol palmitate at 12 weeks in terms of Schirmer-1 test(p=<0.01), tear prism height on ASOCT(p = 0.02), Rose Bengal staining score of cornea(p = 0.01) and conjunctiva (p < 0.01), reduction of ocular surface keratinisation on impression cytology(p = 0.01) and subjective evaluation using OSDI questionnaire(p = 0.04).Impression cytology revealed goblet cells in Retinol palmitate group at 1 week after initiation of therapy, which increased further at 1 month follow up but reduced at 3 months. No goblet cells were seen in control group at any follow-up. No significant difference was noted between the two groups in terms of visual acuity, tear film breakup time, inflammatory cells on impression cytology and inflammatory markers in tears.
Conclusion: Topical Retinol palmitate is a safe and effective drug in cases of chronic SJS with ocular surface keratinisation. It has the potential to reverse keratinisation of the ocular surface and promote development of goblet cells. However, the survival of goblet cells is not long lasting.
