In vivo confocal microscopy findings about ocular surface recovery in patients following pterygium excision combined with conjunctival autograft.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo 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.
methodsPatients 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. IVCM was performed in the affected eyes, 6 months after pterygium excision. The images of the central conjunctival cells in the recipient and donor areas, the cells of each layer of the cornea around the recipient and donor area (around 2 mm from the nasal and upper corneal margins), and the structures of the corneal margins were recorded in the affected eyes and statistically compared with the corresponding areas in the control eyes.
resultsSeventeen eyes of 14 patients with primary pterygium located on the nasal side (mean 64 ± 8.74 years old), and 17 eyes of nine patients as age-matched normal controls were included. Compared with those of normal eyes, the density of corneal pterygoid epithelium around the recipient area (5104 ± 599 cells/mm
conclusionsPterygium excision combined with autologous conjunctival transplantation with corneal stem cells can better promote the repair of most corneal cells around the recipient area and fence-like structures of the corneal rim 6 months postoperatively, but there may be some damage to the corneal conjunctival structures around the donor area.
