An 8-year-old boy was referred for sight-threatening right eye (RE) sclerocorneal cyst. On presentation, BCVA was + 6.00/−6.00 × 140 (6/12). Right sclerocorneal cyst was seen nasally [Figure 1]. B-scan ultrasonography showed an intrascleral cyst without extension into the vitreous cavity and anterior segment optical coherence tomography (AS-OCT) revealed an extension of the scleral cyst into the corneal stroma [Figure 2]. The patient underwent irrigation of the cyst with 5-Fluorouracil (5-FU) 5% and sterile water. Post irrigation the scleral cyst wall was excised, and residual thin sclera was covered with a scleral patch graft. Postoperatively, the patient received topical prednisolone 1% and chloramphenicol 0.5% 2 hourly, which was tapered accordingly. The cyst resolved completely by the third month postoperatively [Figure 3]. Right eye refraction improved to +1.50/-1.50x140 (6/9) and there has been no recurrence of the cyst in the 2-year follow-up period post-surgery [Figure 4].

| Discussion|| |
Conservative management is usually preferred for nonvision threatening sclerocorneal cyst due to its high recurrence rate, while surgical intervention is reserved for sight-threatening sclerocorneal cysts. However, there is no consensus on the best surgical approach for the management of a sclerocorneal cyst. Complete eradication of entrapped epithelial cells within the cyst is the key factor for the prevention of recurrence.
Chemical solutions such as 96% ethanol, 10% trichloroacetic acid, and distilled water have been used for irrigation of the cyst to eradicate the epithelial cells. Kalamkar and Mukherjee did deroofing of scleral cyst with a thorough scraping of epithelial cells over the base and sidewalls of the scleral cyst.
In view of the large sclerocorneal cyst in our patient, we chose to irrigate the cyst with sterile water and 5-FU followed by scleral deroofing and scleral patch. Maintenance of a closed system during irrigation is important to prevent leaking of the chemicals into the anterior chamber, which can lead to damage of the corneal endothelium.
