“…1,2,3,7 Infectious scleritis is most commonly caused by Pseudomonas aeruginosa; however, other organisms that have been isolated from calcific plaques include fungi, Streptococcus and Stenotrophomonas maltophilia. 7,8,9 The calcific plaque acts as a nidus for organisms and, therefore, infectious scleritis can be precipitated by the removal of the plaque as this disrupts the ocular surface integrity. 7,9 Thiotepa is a radiomimetic alkylating agent that has been used in the post-operative period and reduced recurrence rates to 3% -28%.…”

The purpose of this article was to report a late complication of adjuvant beta-radiation after pterygium surgery. This is a case report of a 56-year-old black female patient who presented with an infectious scleritis associated with scleral necrosis and dystrophic calcification. She had undergone pterygium surgery with adjuvant beta-irradiation six years before. She was managed with topical antibiotics and patch graft, with a good outcome. Beta-radiation is associated with visually significant long-term complications and should be avoided. We recommend an excision with extended tenonectomy and free autograft as the procedure of choice.

Purpose: To investigate the long-term efficacy and stability of the use of various reinforcement material grafts on scleromalacia.Methods: This retrospective study was conducted on scleromalacia patients who underwent surgical treatment with reinforcement material grafts from January 2012 to March 2019. The choice of amniotic membrane, Tenon’s capsule, acellular sclera, or collagen matrix implanted in the area of scleromalacia was made based on disease severity. Amniotic membrane transplantation with a pedicular rotatory inferior conjunctival flap was performed to prevent having a bare sclera. The patient demographics, cause of scleromalacia, best-corrected visual acuity (BCVA), recurrence rate, postoperative complications, and restoration appearance were evaluated.Results: A total of 58 patients (58 eyes) were enrolled in this study. The mean age of patients was 65.7 ± 9.6 years, and 32 patients (55.2%) were women. The mean follow-up period was 28.1 ± 17.3 months. The most common cause of scleromalacia was pterygium operation (53 patients, 91.4%). The reinforcement materials were mainly amniotic membrane (31 patients, 53.4%) and acellular sclera (15 patients, 25.7%). There was no recurrence of scleromalacia or structural instability during the follow-up period. The preoperative and postoperative mean BCVA values were 0.24 ± 0.24 and 0.21 ± 0.23 logMAR, respectively. Wound dehiscence (three patients, 5.2%) and conjunctival cyst (three patients, 5.2%) occurred with the highest frequency.Conclusions: The use of the appropriate reinforcement material graft according to the severity of scleromalacia and amniotic membrane transplantation using a pedicular rotatory inferior conjunctival flap to prevent a bare sclera can be effective for treating scleromalacia, without long-term recurrence.
