Clinical Study of Thyroid Orbitopathy
Journal Title: Ophthalmology and Allied Sciences - Year 2019, Vol 5, Issue 1
Abstract
Aim: To study the age, sex, causal distribution, incidence and various modes of presentation of Thyroid Orbitopathy. Methods: 40 patients with a diagnosis of Thyroid Orbitopathy seen between October 2016 - October 2018 were included in this study. A complete ophthalmic examination including visual acuity, ocular motility, exophthalmometry, intraocular pressure, slit lamp examination and fundoscopy was done. Results: Among 40 patients with Thyroid Orbitopathy, 28 (70%) were females and 12 (30%) were males. Mean age of the patients was years 41.82 years (range 18-67). The female: male ratio was 2.3:1. 28 patients (70%) had Grave’s hyperthyroidism, 8 patients (20%) had euthyroidism and 4 patients (10%) were hypothyroid. 80% of the patients had bilateral involvement. The most common ocular signs were eyelid retraction (80%), periorbital oedema (62.5), proptosis (60%) and chemosis (60%). Involvement of extraocular muscles in the descending order of frequency was inferior rectus (70%), medial rectus (50%), superior rectus (27.5%) and lateral rectus (15%). Coclusion: Eyelid retraction was the most common clinical sign of Thyroid Orbitopathy in our patients. On orbital computed tomography (CT) scanning inferior rectus was the most commonly involved muscle. Lower eyelid retraction should be included in the diagnostic criteria in Asian patients.
