Purpose: To study the safety and efficacy of pterygium extended removal followed by extended conjunctival transplant for recurrent pterygia.
Methods: Thirty-three eyes of 33 subjects with recurrent pterygia were enrolled in this prospective case series study. Pterygium extended removal followed by extended conjunctival transplantation was performed in all subjects. One surgeon (WA) performed all surgeries. All subjects completed follow-up for at least 12 months and were evaluated for recurrence and complications.
Results: The mean age of the participants was 41.2 ± 10.3 years (range 22-60), 7 females (21.2%). The mean duration of follow-up was 25.64 ± 9.24 months (range 12-43). Corrected distance visual acuity (decimal notation) improved from 0.69 ± 0.22 (range 0.2-1.0) at presentation to a 1-year postoperative value of 0.83 ± 0.2 (range 0.3-1.0). No recurrence was reported in all subjects throughout the follow-up period. Transient graft swelling was recorded in 14 cases (42.4%) and resolved in all cases by the first week. All patients developed variable degrees of transient postoperative diplopia that resolved completely by the first 6 weeks. Donor site granuloma developed in 4 cases (12.1%). Spontaneous resolution was observed in 3 cases, while in one case, surgical excision was performed 2 months after the procedure.
Conclusions: In this study of eyes with recurrent pterygia, pterygium extended removal followed by extended conjunctival transplant was found safe and effective with no recurrence and minimal postoperative complications.

We describe a novel technique for recurrent pterygium and assess the advantage of properties of extended tenonectomy, amniotic membrane transplantation, and limbal epithelial transplantation in terms of recurrence rate, postoperative symptoms, postoperative orthoptics, and other complications. A total of nine eyes with recurrent pterygium underwent PERMISLET, i.e.

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.

The ocular safety of 222-nm far-ultraviolet-C (UV-C) irradiation, widely recognized for its germicidal properties, was evaluated in a clinical setting to assess its long-term health effects on the human eye. This prospective observational study involved a 36-month follow-up of physicians working in an ophthalmic examination room equipped with 222-nm UV-C lamps. Initially, a 12-month observation showed no signs of acute or chronic ocular damage.

Article Synopsis
- Pterygium colli, a congenital neck deformity often seen in Turner syndrome, requires suitable surgical repair methods, whose effectiveness is difficult to determine.
- A literature review of 16 articles from 1937 to 2020 identified and categorized lateral surgical techniques based on their aesthetic outcomes and results.
- The study concluded that procedures using cervical advancement flaps (especially those by Reichenberger and Mehri Turki) were the most effective for achieving optimal neck contour and minimal visibility of scars.

Article Synopsis
- Popliteal pterygium syndrome (PPS) is a rare genetic condition affecting the face, limbs, and genital areas, characterized mainly by a restrictive band known as popliteal pterygium.
- This band creates a contracture that runs from the ischial tuberosity to the calcaneum, making surgical correction challenging due to its dense fibrous nature.
- The report discusses a case where a PPS patient has family members diagnosed with Van der Woude syndrome, highlighting that a combination of surgery and strong parental support is necessary for effective rehabilitation since single-stage surgeries are often unsuccessful.
