The differential diagnosis for a limbal nodule can include: Pinguecula; Early Pterygium; Foreign body / foreign body granuloma; Phlycten, an inflamed nodule of lymphoid tissue; Episcleritis; Scleritis; Granuloma
The lacrimal caruncle, or caruncula lacrimalis, is the small, pink, globular nodule at the inner corner (the medial canthus) of the eye. [1] It consists of tissue types of neighbouring eye structures. It may suffer from lesions and allergic inflammation.
The tear ferning test reveals abnormalities of the mucous component of the tear film, making it useful as a predictor of a person's tolerance of hydrophilic soft contact lenses. [7] Contact lens intolerance can also result from the elevation of the peripheral edge of the contact lens if it overlies a pinguecula.
A halo sign refers to a GGO that fills the area around a consolidation or nodule. This is a most commonly seen in various types of pulmonary infections, including CMV pneumonia, tuberculosis, nocardia infection, some fungal pneumonias, and septic emboli. Schistosomiasis, a parasitic infection, also commonly presents with the halo sign ...
Most cases of episcleritis resolve within 7–10 days. [2] The nodular type is more aggressive and takes longer to resolve. [2] Although rare, some cases may progress to scleritis. [13] However, in general, episcleritis does not cause complications in the eye. [13] Smoking tobacco delays the response to treatment in patients with episcleritis. [14]

Sympathetic ophthalmia (SO), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity ...
The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition. [4] Often discovered unintentionally on a chest x-ray, a single nodule in the lung requires assessment to exclude cancer. [9]
