Episcleritis is a common condition, and is characterized by the abrupt onset of painless eye <a href="/wiki/Hyperaemia" title="Hyperaemia">redness</a>. </p><p>There are two types of episcleritis, nodular and simple. Nodular episcleritis lesions have raised surface. Simple episcleritis lesions are flat. There are two subtypes. In diffuse simple episcleritis, inflammation is generalized. In sectoral simple episcleritis, the inflammation is restricted to one region. </p><p>Most cases of episcleritis have no identifiable cause, although about a third of cases are associated with various systemic diseases. Often people with episcleritis experience it recurrently. Treatment focuses on decreasing discomfort, and includes lubricating eye drops. More severe cases may be treated with topical corticosteroids or oral anti-inflammatory medications (<a href="/wiki/Non-steroidal_anti-inflammatory_drug" class="mw-redirect" title="Non-steroidal anti-inflammatory drug">NSAIDs</a>). </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Signs_and_symptoms">Signs and symptoms</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Episcleritis&action=edit&section=1" title="Edit section: Signs and symptoms"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Episcleritis.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/41/Episcleritis.jpg/220px-Episcleritis.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/41/Episcleritis.jpg/330px-Episcleritis.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/41/Episcleritis.jpg/440px-Episcleritis.jpg 2x" data-file-width="4160" data-file-height="3120" /></a><figcaption>Episcleritis of a 40 year old female</figcaption></figure> <p>Symptoms of episcleritis typically include painless redness of the eye (mild pain is possible but atypical), and <a href="/wiki/Watery_eyes" class="mw-redirect" title="Watery eyes">watery eyes</a>.<sup id="cite_ref-EpiscleraScleraConj_2-0" class="reference"><a href="#cite_note-EpiscleraScleraConj-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> The pain of episcleritis is typically mild, less severe than in <a href="/wiki/Scleritis" title="Scleritis">scleritis</a>,<sup id="cite_ref-Cecil_3-0" class="reference"><a href="#cite_note-Cecil-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> and may be tender to palpation.<sup id="cite_ref-ColorAtlasFamily_4-0" class="reference"><a href="#cite_note-ColorAtlasFamily-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p>There are two types of episcleritis: the diffuse type, where the redness involves the entire episclera, and the nodular type, where the redness appears more <a href="/wiki/Nodule_(medicine)" title="Nodule (medicine)">nodular</a>, involving only a small, well-circumscribed area (<a href="/wiki/Circular_sector" title="Circular sector">sectoral</a>).<sup id="cite_ref-WillsEye4th_5-0" class="reference"><a href="#cite_note-WillsEye4th-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> The diffuse type of episcleritis may be less painful than the nodular type.
