AI Article Synopsis
- - OSSN is a type of eye cancer that can come back if only treated by cutting it out, so using a special therapy called brachytherapy after surgery helps prevent it from returning.
- - In a study, 9 patients with OSSN had brachytherapy together with other treatments, and they were checked for issues over a few years.
- - The results showed that none of the patients had their cancer come back, and they kept their eye function, although a couple had minor problems from the treatment.
Article Abstract
Purpose: Ocular surface squamous neoplasia (OSSN) has a high recurrence rate if only treated with surgical excision, especially in cases with positive excision margins. To reduce recurrence, we used brachytherapy after surgical excision for limbal and bulbar lesions in addition to chemotherapy/immunotherapy, cryotherapy, or external beam radiotherapy as adjunctive or primary therapies.
Methods: Nine eyes with isolated OSSN lesions were included in the study. Adjunctive brachytherapy with Ruthenium-plaques was administered. The follow-up included regular biomicroscopic slit-lamp examination and photo-documentation. Additionally, a staging check for metastasis was performed in cases with squamous cell carcinoma (SCC).
Results: The average age of patients at the time of presentation was 66 ± 12 years. Follow-up time was 52.8 ± 44.6 months. The maximal tumour base varied between 3 and 28 mm. SCC was confirmed by histology in all cases. No recurrences were recorded during the follow-up, and organ salvage and eye function preservation were achieved. Radiotherapy-induced complications included secondary glaucoma (n = 1) and scleral melting (n = 1). Other complications, such as radiogenic retinopathy, were not observed.
Conclusion: Brachytherapy with Ruthenium-plaques offers an additional option for adjunct treatment of limbal and bulbar OSSN presenting with only a focal spread. Organ salvage can be achieved with a low complication rate and recurrence-free survival. This technique offers globe salvage in patients with tumours involving intraocular infiltration.

Background/aims: To identify the risk factors for neuropathic corneal pain (NCP) following corneal refractive surgery and to report its clinical manifestations, imaging and proteomic characteristics.
Methods: This 1 year prospective cohort study included 100 eyes that underwent small incision lenticule extraction (SMILE) or laser-assisted in situ keratomileusis (LASIK). Ocular surface assessments, in-vivo confocal microscopy scans, tear neuromediators and proteomics analyses were performed.

Aim: To analyse the clinical and demographic profiles of patients with vernal keratoconjunctivitis (VKC) and propose a grading for VKC based on corneal status and symptom periodicity rather than disease activity.
Methods: Retrospective observational study from January 2015 to January 2020 in India. VKC grading was based on past/present clinical signs and frequency of symptoms rather than disease activity.

In this study, three novel derivatives of benzo[b]thiophene-2-carbaldehyde (BTAP1, BTAP2, and BTAP3) were successfully synthesized and comprehensively characterized using spectroscopic techniques including FTIR, UV-VIS, HNMR, and CNMR. Thermal analysis through TGA and DTA demonstrated remarkable thermal stability with a maximum threshold at 270 °C. Spectroscopic investigations revealed π → π* transitions in all compounds, attributed to the conjugated system comprising benzothiophene rings connected to bromophenyl/ aminophenyl/phenol rings via α, β-unsaturated ketone bridges.
