Purpose This study aimed to assess the effectiveness of an innovative intrastromal suturing technique in experimental rabbit model, comparing it standard interrupted suturing, loose suture, and with knot exposure. Methods Fourteen adult male New Zealand White rabbits were included this study. Each underwent both eyes, divided into four groups based on techniques. The novel involved burying entire suture material within corneal stroma. Corneal neovascularisation (CoNV) areas evaluated by...

Primary non-Hodgkin lymphoma (NHL) of lacrimal drainage system (LDS) is quite rare in children, but it important to expedite early diagnosis an effort alter possible life-threatening disease since they are usually misdiagnosed as chronic dacryocystitis. In the literature, there few examples tumors LDS children. The authors herein report two pediatric cases extranodal marginal zone mucosa-associated lymphoid tissue (MALT lymphoma) originating from sac attempt increase knowledge about clinical...
