BACKGROUNDNasolacrimal duct obstruction will lead onto dacryocystitis. This may occur in neonates and children and also. In adults it usually has a chronic course which may end in procedures like Dacryocystorhinostomy (DCR). These procedures have significant failure rate.
BACKGROUND Central retinal artery occlusion (CRAO) was first described by Van Graefe in 1859 as an embolic event to the central retinal artery in a patient with endocarditis. CRAO has various causes, but patients typically present with sudden, severe, and painless loss of vision. Retinal arterial occlusions are a cause for profound visual loss in the population. Carotid atherosclerosis is common in elderly people. Dyslipidaemia, hypertension, and diabetes mellitus are factors which accelerate the development of carotid atheromatous plaques. Embolism from the carotid bifurcation is the most common cause of retinal artery occlusions. In retinal arterial occlusion carotid arterial occlusion is usually assessed using radiological techniques. The purpose of this study was to evaluate carotid atherosclerotic disease in patients with arterial occlusions in the eye and determine the relation between arterial occlusions in the eye & carotid artery occlusive disease. METHODS This retrospective study included patients aged thirty and above, who had come with symptoms suggestive of arterial occlusions in the eye and carotid doppler was done. The inclusion criteria included patients diagnosed with the following conditions CRAO, branch retinal artery occlusion (BRAO), ophthalmic artery occlusion, anterior ischaemic optic neuropathy (AION) and cilioretinal artery occlusion. Patients usually present with sudden loss of vision in one eye. After taking a detailed history, all patients were subjected to a thorough ocular examination. Patient’s vision is assessed using Snellen’s visual acuity chart, pupillary assessment done, and fundus examination to look for retinal arterial occlusion is also done. Fundus imaging is also done. Carotid doppler was done to rule out carotid artery occlusive disease. RESULTS Patients presenting with retinal arterial occlusion should be investigated thoroughly for both systemic and local causes of CRAO. The risk of developing arterial occlusions were 1.7 - 9.15 times more in patients with carotid artery occlusion than in patients with normal carotids. Arterial occlusion was more found in patients with 70 % occlusion of the carotid artery. CONCLUSIONS There was a strong association between retinal arterial occlusions and carotid artery occlusion.

BACKGROUND Thyroid eye disease is a relatively rare condition, with an incidence of 2.9 to 16.0 cases per 100 000 population per year. Approximately 50 % of patients with Graves’ disease (GD) develop clinically apparent thyroid eye disease. It may cause severe damage to vision and orbital architecture. It is the most frequent cause of unilateral or bilateral proptosis in adults. METHODS A cross sectional study of 80 patients with GD was carried out in association with thyroid clinic of Government Medical college Thiruvananthapuram for a period of 1 year from April 2017 to March 2018. Subjects who have a prior diagnosis of Graves’ disease including those who are on antithyroid drugs were included in the study. Patients who are sick due to other systemic diseases like cardiac failure and end stage renal disease were excluded. RESULTS Eighty patients with mean age of 45.31 years were studied. Out of them, 66% were females and 34% were males. Ophthalmopathy was present in 38.8%.Majority had mild and bilateral disease (61.2 %). Only a small percentage had sight threatening disease (6.4 %).The mean age of patients with ophthalmopathy was 47.93. Major population with ophthalmopathy was females. Majority of patients with ophthalmopathy (64.5 %) retained a good visual acuity better than 6 / 9. Lid retraction was the most common manifestation among patients with Graves’ ophthalmopathy that is 74.2% followed by exophthalmos (64.5 %) and eye movement restriction and soft tissue involvement (58.1 %). Diplopia, optic nerve dysfunction were rare (3.2 %). Only 19.3 % patients had active disease according to clinical activity score. Major clinical sign of activity was redness of conjunctiva. Maximum no. of patients with active disease had a clinical activity score of 4. Smoking showed a significant association with the severity of ophthalmopathy. (p value 0.001) There was a significant association between age and activity of disease. (p value 0.021). No association was found between duration of disease with presence or severity of ophthalmopathy. There was no association between co- morbidities with presence or severity of ophthalmopathy. No association was found between hormone status and presence or severity of ophthalmopathy. CONCLUSIONS Our results indicated that the prevalence of ophthalmopathy in our population with GD evaluated at our tertiary care centre was similar to that reported in the Caucasians of European origin. Clinically active and sight threatening ophthalmopathy was uncommon. KEYWORDS Graves’ Disease, Ophthalmopathy
