Mechanisms and biomarker candidates in pterygium development [PDF]

, 2020
Pterygium pathogenesis has been mainly associated with UV light exposure; however, this association remains quite controversial. The complete mechanism of pterygium also remains to be clarified.

Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

The role of heredity in pterygium development

International Journal of Ophthalmology, 2014
Several risk factors, which include heredity, ultra-violet (UV) light and chronic inflammation, contribute to pterygium development. However, there is no report integrating these factors in the pathogenesis of pterygium.

Human ocular‐discomfort‐free thresholds for 222 nm Far‐UVC irradiation: A prospective interventional study

Photochemistry and Photobiology, EarlyView.
Eye discomfort induced by 222 nm far‐UVC irradiation is significantly correlated with both irradiance and radiant exposure dose. The red circles indicate conditions with significant differences in the number of eye discomfort compared to the control group (blue circles), while the green circles indicate conditions with no difference from the control ...

Treatment of primary pterygium: Role of limbal stem cells and conjunctival autograft transplantation

Oman Journal of Ophthalmology, 2009
Purpose: The limbus and its stem cells are very important in the pathogenesis of pterygium. In this study, the efficacy of limbal stem cells and conjunctival autograft transplantation for the treatment of primary pterygium will be assessed.

Early oxidation‐related changes in aqueous humor following eye exposure to ultraviolet‐A radiation

Photochemistry and Photobiology, EarlyView.
UVA exposure induces early oxidative alterations in the aqueous humor, disrupting its antioxidant balance. Levels of ascorbic acid, reduced glutathione (GSH), and the GSH/GSSG ratio decrease, while oxidized glutathione (GSSG), S‐glutathionylated proteins (PSSG), and malondialdehyde (MDA), a lipid peroxidation by‐product, increase.

Conjunctival graft from pterygium tissue itself in primary pterygium surgery [PDF]

, 2021
Background: The aim of a study was to assess the efficacy of a new surgical technique that uses conjunctival tissuefrom the pterygium itself as a graft with a 180-degree rotation and fibrin glue in the primary pterygium surgery. Material and methods: For

Comparison of conjunctival pedicle flap to corneal fixation strength achieved by Tisseel® fibrin glue, ethyl cyanoacrylate adhesive, ReSure® hydrogel sealant, and conventional suturing with 8‐0 VICRYL® ophthalmic suture

Veterinary Ophthalmology, Volume 28, Issue 2, Page 253-263, March 2025.
Abstract Objective To determine and compare the fixation strength of conjunctival pedicle flaps to cornea achieved via conventional ophthalmic suture and three different adhesive compounds. Animals Studied Ex vivo porcine globes. Procedures Following a 6 mm wide 500‐micron‐restricted depth lamellar keratectomy, conjunctival pedicle flaps were secured ...
