Amniotic membrane combined with MMC has similar recurrence rate to CA combined with MMC, in patients with recurrent pterygium. Similar outcomes and complication rates make AMT-MMC a promising method for the treatment of recurrent pterygium cases.
Amniotic membrane closure and conjunctival autografts seem to be equally effective in the prevention of recurrence of primary pterygium. Conjunctival autografts combined with mitomycin C are as effective as the above two techniques to prevent recurrence in the treatment of recurrent pterygium. Due to the larger area of subconjunctival fibrosis, a larger defect area is created after the excision of pterygium tissue and a larger graft is needed to close this defect in recurrent pterygium. This factor can guide the surgeon during the planning of the surgery to choose the most appropriate technique for closure of the defect.
AMT is effective to promote corneal healing in patients with persistent epithelial defect and appeared to be helpful after surgery to release pain. It can be successfully used as an alternative to conjunctival autograft for conjunctival surface reconstruction.
The clinical and histopathological findings in a 40-year-old man with a lacrimal sac tumor are reported. Although the clinical history indicated a lacrimal sac obstruction and recurrent dacryocystitis, the lesion was diagnosed by light microscopy as a squamous cell carcinoma.
A 53-year-old woman was admitted to the hospital one year after the onset of her complaints. She suffered from epiphora and swelling in the lacrimal sac region. Biopsy revealed islets of classical basal cell carcinoma with peripheral formation of palisades within a hyperemic stroma. During surgery, the lacrimal drainage system and neighboring bony structures were completely excised. No local recurrences were detected on orbital tomography performed 6 and 15 months postoperatively. As far as the authors know, this is the first case of basal cell carcinoma in the lacrimal sac reported in the literature.
Precorneal tear film stability was worse in patients treated with OAD; however, impression cytology analysis and Schirmer test results were similar in all groups.
CommentMS in children can also follow an optic neuritis episode, with a higher likelihood in young girls. 2,5 Unilateral presentation of optic neuritis in children is usually associated with excellent visual prognosis, but with a high probability of developing MS. 5 In contrast, children with bilateral optic neuritis develop MS much less frequently (7% to 9%). [3][4][5] Kriss et al. 2 reported that 74% of bilateral optic neuritis patients had swollen optic discs. Our case presented with bilateral aute retrobulbar optic neuritis without swelling of discs and no seizures. Immediate steroid administration resulted in good recovery.We should always consider that children who present with optic neuritis can develop MS. We recommend careful observation and long-term follow-up in such cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
