CLINICO DERMOSCOPIC STUDY OF PATTERNS OF PERIORBITAL HYPERMELANOSIS

Background:Periorbital hyperpigmentation (POH) is a routinely encountered condition in dermatology practice. Studying the clinical features and its correlation with dermoscopy will help in better understanding of patterns of periorbital pigmentation and its evolution. 2POH is a condition characterised by bilateral homogenous, hyperchromicmacules and patches, primarily involving the upper and the lower eyelids. 3It is a common problem with multifactorial etiology, is evident on the face and can affect patients quality of life (QoL). 7 Aim: To study dermoscopic patterns of periorbital hyper melanosis in patients presenting to dermatology, venereology,leprosy OPD in Bhaskar General Hospital from January 2022 to June 2022. Methods: 50 patients with periorbitalhypermelanosiswere included in the study.Dermilite 4 Dermoscope (10X magnification) with polarised light was employed in the study. Results:Out of 50 patientsondermoscopy mixed type was 76.4%, pigmented 11%, vascular 10.6%, structural 2%. Conclusion:Periorbital melanosis presents as multifactorial entity with constitutional type being the most common. The most common pattern seen on dermoscopy is mixed.It is essentially a clinical diagnosis, but dermoscopy might aid in further classification of the disease. Also, it might give us a clue regarding the etiology and help in the treatment, as different types of POH respond to varying treatments.7
