ABSTRACT
To determine the incidence and density of Demodex species on the eyelashes of subjects with normal eyelids, anterior blepharitis [AB], meibomian-gland dysfunction [MGD], and mixed blepharitis [MB]. One hundred and fifty consecutive patients diagnosed with AB, MGD, and MB were recruited. An additional 50 individuals were recruited who were free of lid and margin disease to serve as a control group. All patients underwent a standard eye examination. Data on ocular symptomatology were gathered. Digital photography was performed of the lid margins. Lash sampling was performed by epilating the lashes and the lashes were checked for Demodex based on morphology using light microscopy. The total number of mites were tabulated for each eye. Comparison between the affected eyes and the control eyes was performed. Data were analyzed using the Chisquare test. A total of 200 patients were included. Twenty percenth had AB, 40% had MGD, and 40% had MB. The incidence of Demodex infestation was 90% in cases of AB, 60% in MGD cases, and 90% in MB cases. The incidence of Demodex in control subjects was 18%. The incidence and density of Demodex infestation was highest in patients with AB and MB. Lid irritation and presence of cylindrical dandruff were indicative of a high-density infestation. These signs should alert the clinician to treat concomitant Demodex infestation
ABSTRACT
Primary localized amyloidosis of the conjunctiva is a rare occurrence. This case report describes a 35-year-old male, who presented with drooping of both upper eyelids and a pricking sensation in the left eye. Examination of the conjunctiva showed granular swellings. The biopsy revealed amyloid deposition. Systemic amyloidosis was ruled out on further investigation. To our knowledge, this is the first report of amyloidosis of the conjunctiva and tarsus, presenting as ptosis with entropion, from India
