Conjunctival Retention Cysts: Outcomes of Aspiration and Sclerotherapy With Sodium Tetradecyl Sulfate

Long term outcomes of transcutaneous non-image guided bleomycin sclerotherapy in orbital/adnexal lymphatic malformations: a protocol-based management in 69 eyes

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.

Conjunctival Epithelial Inclusion Cyst following Evisceration with Primary Orbital Implantation

A 29-years-old Turkish man who had undergone evisceration with primary orbital implantation 20 months prior complained of difficulty wearing his artificial eye. Slit-lamp examination revealed a conjunctival cyst in the center of the anophthalmic socket, with no evidence of scleral or orbital implant exposure. The cyst was completely excised under general anesthesia and did not require use of any sclerosing substance or dye. At 6 months postoperatively, there was no recurrence of the cyst or exposure of the sclera or orbital implant. As the upper and lower fornices were sufficiently deep, the patient could wear his artificial eye.
