Ocular Manifestations in Head and Neck Cancer: A Cross-Sectional Study from a Tertiary Care Centre from South India.

Introduction: Head and neck cancers (HNCs) present a significant global health burden, especially in India, where oral cavity cancers, notably affecting the tongue, are prevalent. A substantial portion of global HNCs (57.5%) is concentrated in Asia, India contributing with 30%. Despite advancements, challenges persist due to HNCs' invasive nature and metastatic potential. This study aims to explore the link between HNCs and ocular manifestations. Methods: A cross-sectional study was conducted at Bangalore Medical College and Research Institute involving 47 patients with diagnosed HNCs and ocular complaints. Clinical evaluations encompassed visual acuity, anterior and posterior segment examinations, and specialized investigations when necessary. Results: A diverse range of malignancies were observed, with SCC maxilla and xeroderma pigmentosa, each accounting for 10.63% of cases. Ocular examinations unveiled visual acuity challenges, anterior segment findings like masses, exotropia, pigmented lesions, and varied fundus abnormalities. The anterior segment findings encompassed masses often accompanied by protrusion or relative afferent pupillary defect (RAPD). Additionally, exotropia, pigmented lesions, and other conditions were observed. Fundus examination revealed a spectrum of findings, including media haziness (10.63%), lack of view (17.02%), and pale discs (6.38%). Treatment plans were diverse, including excision biopsies (42.55%), exenteration procedures, Mitomycin-C applications, and referrals for chemotherapy and radiotherapy. Conclusion: The present study underscores the significance of ophthalmological assessment and investigations in patients with diagnosed HNCs, emphasizing the value of early detection and intervention.
