Easy Bruising
He had hypermobility of large joints, easy bruising, thin and hyperextensible skin with visible veins, which were also described in his elder brother. [ncbi.nlm.nih.gov]
Respiratoric
-
Aspiration
A paracentesis was made, and aqueous was aspirated until the anterior chamber had collapsed enough to take up a more physiologic shape. The donor corneoscleral graft was sutured into the prefashioned scleral bed with long, interrupted sutures. [ncbi.nlm.nih.gov]
Jaw & Teeth

High Arched Palate
Systemic examination may show features of blue sclera, skeletal abnormalities, hyper-mobility of joints, hearing loss, abnormal dentition or high-arched palate. There may be features specific to each syndrome. [aimu.us]
These include features mentioned earlier of blue sclera, joint hypermobility, skeletal abnormalities, hearing loss, abnormal dentition, high-arched palate, as well as other features specific to each syndrome. [ncbi.nlm.nih.gov]
Musculoskeletal

Back Pain
My PT thinks my back pain is a fibromyalgia related issue, but my PCP thinks it could be my gallbladder....don’t you love when doctors have conflicting opinions I’ll be going in for an ultrasound on Wednesday to check my gallbladder so hopefully we’ll [thepicta.com]
Eyes
-
Blue Sclera
Marshall-Stickler syndrome may exist in the differential diagnosis of keratoglobus with blue sclera. [ncbi.nlm.nih.gov]
Two siblings had in common the features of keratoglobus, blue sclera, atypical face, hearing loss, and hypermobile joints. [ingentaconnect.com]
-
Iridodonesis
Associated findings include anterior megalophthalmos, enlarged ciliary ring with zonular stretching (leading to phacodonesis), ectopia lentis, iridodonesis, iris stromal hypoplasia, posterior embryotoxon, transillumination defects, Krukenberg spindles [medical-dictionary.thefreedictionary.com]
Iridodonesis was noted in left eye. Retinal evaluation of LE revealed retinal detachment (RD) with posterior staphyloma due to high myopia, hereas RE was within normal limits. Intraocular pressure was normal in both eyes. [mendeley.com]
Other ocular abnormalities associated with megalophthalmos anterior include iridodonesis, iris stromal hypoplasia, phacodonesis, ectopia lentis, cataracts, and pigmentary glaucoma with Krukenberg spindles (Vail, 1931; Neumann, 1984; Javadi, 2000; Chien-Kuang [webeye.ophth.uiowa.edu]
Workup
Bilateral cases are often associated with systemic disorders and warrant a complete genetic workup. [entokey.com]
NOTE: Children should be referred for an extensive developmental workup Differential Diagnosis Simple megalocornea Megalophthalmos anterior Congenital glaucoma Keratoglobus High myopia References Basti S and Koch DD. [webeye.ophth.uiowa.edu]
Treatment
Intracameral injection of C(3)F(8) may possibly be a viable treatment option for acute hydrops in a case of corneal ectasia. [ncbi.nlm.nih.gov]
Treatment [ edit ] Treatment includes the use of protective eye glasses. [2] A number of surgical options are also available. [2] Further progression of the disease usually leads to a need for corneal transplantation because of extreme thinning of the [en.wikipedia.org]
Treatment of acute hydrops can be both conservative and surgical. [doi.org]
Treatment Treatment Options: Treatment beyond corneal repair is limited. References [disorders.eyes.arizona.edu]
Prognosis
Prognosis [ edit ] Keratoglobus continues to be a somewhat mysterious disease, but it can be successfully managed with a variety of clinical and surgical techniques. [en.wikipedia.org]
Prognosis Keratoglobus continues to be a somewhat mysterious disease, but it can be successfully managed with a variety of clinical and surgical techniques. [wikidoc.org]
The prognosis for keratoglobus is poor. [eyewiki.aao.org]
Etiology
We aimed to discuss the etiology and the association of keratoglobus with some systemic abnormalities caused by collogen tissue disturbance, and make a brief review about the recent literature concerning the management of keratoglobus patients. [ncbi.nlm.nih.gov]
The etiology is unknown. [eyewiki.aao.org]
Epidemiology
Epidemiology [ edit ] It is a much rarer condition than keratoconus, which is the most common dystrophy of the cornea. [4] Similar to keratoconus it is typically diagnosed in the patient's adolescent years and attains its most severe state in the twenties [en.wikipedia.org]

Epidemiology To date, no bio-statistical studies have evaluated either the inci-dence or prevalence of PMD; however, the general consensus in theliterature is that PMD is a rare condition, less common than otherectatic diseases such as keratoconus [68 [pdfslide.net]
EPIDEMIOLOGY: Incidence: Unknown Gender: 90% male predominance Genetics: X-linked recessive. Band Xq12-q26 (most likely q21-q23) Small number via autosomal dominant or recessive. [webeye.ophth.uiowa.edu]
Pathophysiology
It is sometimes equated with "megalocornea". [1] Pathophysiology [ edit ] Keratoglobus is a little-understood disease with an uncertain cause, and its progression following diagnosis is unpredictable. [en.wikipedia.org]

Pathophysiology The pathophysiologic mechanism is unknown. Primary prevention An effective means of prevention has not been discovered. [eyewiki.aao.org]
Prevention
To report a case of corneal hydrops in a patient with keratoglobus that was managed with endothelial keratoplasty to achieve corneal stability and prevent a limbus-to-limbus tear in Descemet membrane. [ncbi.nlm.nih.gov]
Complete removal of the epithelium is important to prevent cystic formations or even melting of the donor lamella, Prof. Busin said. [healio.com]
Primary prevention An effective means of prevention has not been discovered. History Patients usually present with a stable or worsening bilateral visual impairment that cannot be properly corrected with spectacles or contact lenses. [eyewiki.aao.org]
