Scleral Disease
China Medical University NO.4 Affiliated hospital Ophthalmology;
Ophthalmology hospital of China Medical University
Introduction
character
• Outer wall of eye. • Collagen fiber & elastic fiber• Lack of cell and vessels• Less capacity of self repairing—staphyloma
Scleral Disease : Commonly found in inflammation ( disease course deferment , medication inevident
)Scleral Disease Classifications : Episcleritis Scleritis
Episcleritis
Nodular episcleritis : acute in onset
symptoms:unilateral 、 wine 、 round or ellipse limited nodular uplift , diameter 2 ~ 3mm
redness 、 edema irritation Vission not affected concurruent mild iritis the inflammation subsided in 2 to
4 weeks , easily recurrent 。
Episcleritis
Simple episcleritis : periodicity redness and edema light irritation,Vission not affect
ed concurruent lid edema , dise
ase course deferment often found in Women's menstr
ual period self-limited
Episcleritis
Episcleritis Conjunctivitis scleritis
Congestion Localized Diffused, palpebral conjunctiva affected
Congestion and edema
Not affect sclera Affect sclera
Nodules movable unmovable

different diagnoses
Treatment:• Self-limiting• Corticosteroids:

• NSAIDs: po
Episcleritis
Scleritis
• Inflammation of sclera• Severe than episcleritis• Young and mid-age adults• Female>Male• Autoimmune disease• Complicated with general c
ollagenous, granulomatous or metabolic diseases.
pathogeny : Allergic reaction 。 Auto immune connective tissue diseases Metabolic diseases Other : infection spreaded , inflammation spreads in th
e vicinity of the organization 。
Scleritis
anterior Scleritis:disease site : anterior equator , bilateral eye
s current successively 。clinical manifestations : pain, Vision decrease 、 sclera focus
course : long 、 recurrent 、 defermentprognosis : not goodcomplications : Uveitis 、 Keratitis 、 Secondary
glaucoma e.g 。

ns often bilateral eyes concurruent Serious Autoimmun
e diseases
necrotizing anterior scleritis
Posterior Scleritis: disease site : Posterior equator , about 2 %。 clinical manifestations : pain , eyelid and bulbar co
njunctiva edema , eyeball slightly Prominent , extraocular involved 。 Concurruent Uveitis 、Vitreous opacities e.g 。
diagnoses : Examinations , such as B-US 、 CT 、MRI,can show Posterior sclera thickening 。
different diagnoses : Orbital cellulitis , the symptoms and exophthalmus are even Obvious 。
Scleritis
treatment• Pathogeny treatment• Symptomatic treatment : coldly cover 、 Artificial tears
。• Anti-inflammatory treatment : corticosteroids 、 Immun
osuppressant e.g 。• Surgical treatment : necrosic 、 perforative Scleral site
can be done with Allogeneic scleral graft 。• Complications treatment : glaucoma 、 Iridocyclitis.
Scleritis
Sclera staphyloma
• definition : Because of thinning of the sclera , scler
a and deep uveal bulge and expand outward with the function of intraocular pressure,and revealed blue-black color of uveal color 。
• Classification : anterior sclera staphyloma equatorial sclera staphyloma posterior sclera staphyloma
• treatment : 1. Decompression early 2. If the eyes have been suffe
ring from no light perception , And pain ,
eyes can be removed 。
Abnormal scleral color
• Scleral pigment plaques : brown or blue-gray spots currented at anterior sclera surface and entrance of Ciliary vessels 。 Scleral melanosis syndrome 。
• Blue sclera : It is caused by Uveal color under sclera because of thin sclera 。 concurruent congenital anomalies
• Sclera yellow Stained : Jaundice
• Brown macular:Brown-gray spots at sclera , which current at Palpebral fissure area earliest 。
It can be distributed in the sclera, cornea and conjunctiva 。 No clinical significance 。
