1/5. Sclerokeratitis: an unusual presentation of squamous cell carcinoma of the conjunctiva.OBJECTIVE: To describe three cases of squamous cell carcinoma of the conjunctiva presenting with corneal and scleral inflammation, thinning, and perforation without any tumor formation. DESIGN: Three case reports. PARTICIPANTS: Three male subjects aged 76, 66, and 61 years. INTERVENTION: The subjects had symptoms of external ocular inflammation with focal corneal or scleral thinning and inflammation, as well as interstitial keratitis in two cases. Initial diagnosis of sclerokeratitis with limbal thinning was made in all three in addition to a pterygium in case 2. MAIN OUTCOME MEASURES: diagnosis of the carcinoma was delayed for 2 to 24 months in two cases, whereas case 2 was diagnosed on excision of a pterygium from the involved area. RESULTS: All subjects developed intraocular extension after further scleral thinning and perforation without tumefaction. CONCLUSIONS: Squamous cell carcinoma of the conjunctiva may be seen without a distinct mass and can masquerade as sclerokeratitis, scleromalacia, or interstitial keratitis. It seems that diffuse growth with inflammation leads to thinning, necrosis, and perforation of the ocular wall with resultant intraocular spread. Squamous cell carcinoma should be considered in the differential diagnosis of corneal and scleral thinning, perforation, and inflammation of unknown cause, especially in the older male subject.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
2/5. Surgically induced necrotizing scleritis after pterygium excision and conjunctival autograft.PURPOSE: To report a case of surgically induced necrotizing scleritis (SINS) after pterygium excision and conjunctival autograft. methods: A 55-year-old man presented 2 weeks after excision of primary pterygium with conjunctival autograft in the right eye with severe pain in that eye. He had undergone cataract surgery in that eye 8 months before. The graft was pale and white. The underlying sclera was white and avascular. There was marked inflammation adjacent to the site of surgery and graft. A scraping from the graft surface revealed no organisms in smears, and culture revealed no growth. The conjunctival graft was removed. Amniotic membrane transplantation was performed. After surgery, the amniotic membrane was avascular and pale. Systemic steroid therapy was initiated. RESULTS: Three days after initiation of systemic steroid therapy, the graft became vascularized. Over the next 10 days, the eye quietened, conjunctival and scleral inflammation lessened, and the graft was well accepted. CONCLUSIONS: Surgically induced necrotizing scleritis is a rare complication of pterygium excision with conjunctival autograft. A pale graft with underlying avascular sclera and surrounding inflammation should arouse suspicion of this complication.- - - - - - - - - - ranking = 0.6keywords = inflammation (Clic here for more details about this article) |
3/5. Necrotising anterior scleritis after pterygium surgery.Necrotising anterior scleritis is a rare sequela of ocular surgery. Typically an intense scleral inflammation develops at or adjacent to the site of the previous surgery. necrosis supervenes and may then progress circumferentially to involve much of the anterior sclera. Surgically induced necrotising scleritis (SINS) has been previously described after cataract extraction, trabeculectomy, retinal detachment and strabismus surgery. We report three cases of SINS following pterygium excision. In each case the disease was prolonged, progressive and required protracted immunosuppressive therapy.- - - - - - - - - - ranking = 0.2keywords = inflammation (Clic here for more details about this article) |
4/5. A peculiar case of necrotizing sclerokeratitis with pseudomonas infection.A 71-year old woman complains of painless inflammation, discharge and decreased vision at the right eye since two weeks. Eight years before she was operated at this eye for a nasally located pterygium and received adjuvant radiotherapy. On examination a necrotizing scleritis was seen which rapidly involved the cornea and was infected by pseudomonas. Despite intensive antibiotherapy the sclerokeratitis extended further and eventually lead to enucleation. Surgically induced scleritis-especially after pterygium surgery with adjuvant radiotherapy-and complicating pseudomonas infection are discussed.- - - - - - - - - - ranking = 0.2keywords = inflammation (Clic here for more details about this article) |
5/5. pterygium in lepromatous leprosy.Pterygia from the eyes of three lepromatous leprosy patients were histopathologically studied. All of the specimens contained acid-fast bacilli (AFB) and exhibited features of chronic inflammation. In the etio-pathogenesis of the pterygium that occurs in leprosy patients, the chronic inflammation that is a feature of the disease, the involvement of the nerves within the pterygium, the increased exposure to sunlight, dust and wind (especially in patients having lagophthalmos), and the ostrasization by society that necessitates living predominantly outdoor lives, should be taken into account.- - - - - - - - - - ranking = 0.4keywords = inflammation (Clic here for more details about this article) |
