2014年7月1日 · Exposure keratopathy is dryness of the cornea caused by incomplete or inadequate eyelid closure, resulting in evaporative tear loss and tear film insufficiency. Mild cases are usually benign and easily treated, but if severe, undiagnosed, and/or under-treated, drastic consequences can result.

The distribution of the PEE can provide information regarding the underlying etiology. Inferior PEE, as seen in this photograph, can be secondary to exposure, chronic blepharitis, or trichiasis. This patient previously underwent multiple eyelid surgeries resulting in exposure keratopathy.

2020年12月3日 · UV keratitis caused by solar radiation requires a longer period of exposure compared to artificial causes. Natural causes of UV keratitis include exposure to strong solar radiation at high altitude or on snow covered terrain or prolonged viewing of a solar eclipse without proper eye protection (solar eclipse burn) [2].

2008年2月8日 · Keratitis e lagophthalmos is an exposure keratitis resulting from an inability to close the eyelids. In this case the inability was due to a facial paralysis. It is not easy to detect in this photo, but the patient did have a lateral tarsorraphy OD. Please note that the word "lagophthalmos" has an interesting etymological history.

2003年4月12日 · The keratitis usually improves with low-dose topical corticosteroids (0.12% prednisone or equivalent 2 to 3 times per day for a few days up to 2 weeks as recommended by Arffa, p. 323. Leibowitz et al., recommend that acute episodes be treated aggressively with topical steroids and then tapered and discontinued over a 3 to 4 week interval.)

2012年12月31日 · Classic risk factors for reactivation are thought to include stress, illness, menses, immunosuppression, sun exposure, fever, and trauma, though these were not born out by the Herpetic Eye Disease Study.[4] The most significant risk factor for HSV keratitis is a past history of ocular HSV.[1]

2014年3月31日 · o Exposure keratitis o Trachoma Signs • Bilateral gray-white elevated corneal subepithelial nodules in the paracentral or central cornea or near the limbus with annular distribution [4]. • There is a subset of Salzmann’s nodules with associated vascularization [5]. Symptoms • Decreased visual acuity • Asymptomatic

2016年11月18日 · Exposure keratopathy (Figure 17) Secondary sign due to lagophthalmos from eyelid retraction and/or exophthalmos; Predisposes the cornea to bacterial infection (keratitis), which can lead to ulceration, endophthalmitis, and perforation; Multimodal management; Figure 17: Exposure keratopathy.

2021年2月23日 · HSV keratitis can be further categorized into epithelial keratitis (dendritic and geographic) (7, 8), stromal keratitis (interstitial and necrotizing) (9), and endothelial keratitis (disciform) (6, 10). Stromal keratitis, usually in the interstitial form, occurs in 2% of initial episodes and 20-48% of recurrent episodes of ocular HSV disease (11).
