    Abstract:
    OBJECTIVES: To study the efficacy and the long-term outcomes of treating micro and macrocystic orbital and/or adnexal lymphatic malformations (OA-LM) with protocol-based bleomycin sclerotherapy. METHODS: A retrospective interventional study of 69 eyes having OA-LM treated with non-image guided transcutaneous or transconjunctival bleomycin sclerotherapy (1IU/ml aqueous solution) between December 2014 and December 2018. Based on clinical regression, the outcomes were classified as excellent, good, fair and poor. RESULTS: The mean age at presentation was 20 ± 16 years (median 16; range 1 month to 70 years). The orbital-palpebral variant was the most common presentation, seen in 29 patients (42%). Microcystic morphology was seen in 34(49%), macrocystic in 22 (32%) and mixed cyst in 13 (19%) patients. Mean units of bleomycin injected per patient were 9 ± 8 IU (median 5.5 IU, range 1-38 IU). Mean number of treatment sessions required were 2 ± 1 (median 2, range 1-6). The response was excellent in 43 (62%), good in 12 (17%), fair in 9 (13%) and poor in 5 (7%) patients. These responses were comparable across the morphological subgroups (p = 0.24, chi-square test). Adverse reactions noted were inflammation in 11 eyes (16%) and peri-ocular pigmentation in 15 (22%). There was a sustained tumour regression over a mean follow-up duration of 3.5 years (median 3; range 1.5-5 years). CONCLUSIONS: Seventy-nine percent of eyes with OA-LM showed a good outcome with transcutaneous and/or transconjunctival non-image guided bleomycin sclerotherapy with no serious adverse events. The results were promising over long-term follow-up.
