Purpose: To describe the novel use of combined conjunctival rotational autograft (CRA) and intraoperative 0.02% mitomycin C (MMC) in the treatment of primary pterygium and to evaluate its safety and efficacy.
Methods: Prospective interventional case series comparing with historical controls was conducted. Patients with primary pterygium underwent pterygium excision, MMC was applied to the scleral bed after the surface conjunctiva was harvested, and the CRA was sutured back with a 180-degree rotation. Patients were followed for a minimum of 1 year.
Results: Sixty-seven eyes from 67 patients participated in the study, of which 31 (46.3%) were men and 36 (53.7%) were women. The mean age was 58 +/- 10.6 years, (range 36-79 years). There were 2 recurrences (3%), one occurring at month 3 and the other at month 9. Compared with historical controls, CRA-MMC resulted in significantly fewer recurrences than MMC alone (P = 0.005) when adjusted for age and was equally effective when compared with limbal-conjunctival autografts. The main postoperative problem was graft injection, which was noted in 41 eyes (61%) at 1 year.
Conclusions: To the best of our knowledge, this was the first study on the combined use of CRA and MMC in the treatment of primary pterygium. CRA with MMC was found to be effective in the prevention of recurrence. Although injection remained as a cosmetic concern, it was a safe alternative to limbal-conjunctival autograft in cases where mobilizing autologous conjunctival tissue would not be feasible.

Pterygium is an ocular disease in which the conjunctival tissue invades the cornea. When the pterygium tissue reaches the pupillary region, the visual function of the patient is affected. Currently, surgical removal is the only effective treatment.

Pterygium is a nonneoplastic elastotic degeneration characterized by subepithelial growth. It manifests as an ocular lesion originating from the bulbar conjunctiva, extending to the corneal surface, and reaching the visual axis in some cases. Although the exact cause is unknown, prolonged exposure to ultraviolet radiation is considered the most significant contributing factor.

Purpose: To assess the effectiveness and safety of the "hydro-fluorescein" adjunct technique for primary pterygium removal.
Design/methods: A non-randomized prospective study was conducted for various types of pterygium excision with superior bulbar conjunctival autograft (CAG) and fibrin glue. We introduced fluorescein staining to ensure thorough elimination of the Tenon tissue around the bare sclera area and the CAG.

Purpose: To study cellular and neural changes around the donor and recipient areas after pterygium excision combined with autologous conjunctival transplantation using corneal confocal microscopy, we evaluated the postoperative impact of this surgical procedure.
Methods: Patients with primary pterygium located on the nasal side who visited the Department of Ophthalmology of Wuxi Second People's Hospital between April and August 2023 were enrolled. Age-matched healthy eyes were included as the control group.

Objective: To explore the clinical efficacy of modified limbal stem cell transplantation(Modified LSC transplantation) and bandage contact lens(BCL) implantation in pterygium surgery.
Methods: A total of 479 patients with primary pterygium who were admitted to our hospital from March 2019 to March 2023 were randomly divided into three groups: the normal group (Group A: 89 patients), the control group (Group B: 195 patients), and the modified group (Group C: 195 patients). Each group received different intervention measures.
