• Inguinal Hernia

  Both probands had a history of surgery for inguinal hernia; the male patient also reported hydrocele. Nucleotide changes within the coding region of ZEB1 underlie the pathogenesis of PPCD in 4 of 23 Czech probands (17%). [ncbi.nlm.nih.gov]

  Family reports of inguinal hernia, hydrocele, and possible bone anomalies in affected individuals suggest that individuals with TCF8 mutations should be examined for nonocular anomalies. [uniprot.org]

  Only one inguinal hernia was present in our cohort, and did not occur in conjunction with ZEB1 disease. [molvis.org]

  Abstract Congenital hereditary endothelial dystrophy 1 (CHED1) and posterior polymorphous corneal dystrophy 1 (PPCD1) are autosomal-dominant corneal endothelial dystrophies that have been genetically mapped to overlapping loci on the short arm of chromosome [ncbi.nlm.nih.gov]

  These include the long arm of chromosome 20 (20p11.2-q11.2) [10] designated as PPMD 1, the short arm of chromosome 1 (1p34.3-p32) [11] designated as PPMD 2, and the short arm of chromosome 10 (10p11.2) [12] now designated as PPMD 3. Figure 5. [webeye.ophth.uiowa.edu]

  Each chromosome has a short arm designated “p” and a long arm designated “q”. Chromosomes are further sub-divided into many bands that are numbered. For example, “chromosome 5q31” refers to band 31 on the long arm of chromosome 5. [cornealdystrophyfoundation.org]

• Suggestibility

  CONCLUSION: Recent studies suggest that ZEB1 mutations may account for PPCD in 18 to 30% of cases, with the majority of the mutations in exons 5 and 7. [ncbi.nlm.nih.gov]

  Combining the 5 series to date, including this series, suggests ZEB1 mutations in PPCD probably accounts for 25% of the disease. [molvis.org]

• Cryptorchidism

  As cryptorchidism has been previously observed in two other PPCD3 cases, its association with the disease warrants further investigation. © 2014 John Wiley & Sons Ltd/University College London. [ncbi.nlm.nih.gov]

Descemet's stripping automated endothelial keratoplasty (DSAEK) has recently become the preferred treatment for corneal endothelial dystrophies in adults. [ncbi.nlm.nih.gov]

Treatment Treatment Options: Few patients require treatment since the endothelial changes are frequently stable. Among those that do undergo corneal transplantation, the changes often recur in the donor button. [disorders.eyes.arizona.edu]

Until now, a full thickness penetrating graft has been the gold standard for the treatment of endothelial failure in PPCD. [1], [2] Posterior lamellar keratoplasty is a relatively new surgical technique for the treatment of endotheliopathies. [ijo.in]

The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. [orpha.net]

The factor that most prominently influences keratoplasty prognosis is the presence of iridocorneal adhesions.(ABSTRACT TRUNCATED AT 400 WORDS). [ncbi.nlm.nih.gov]

Based on the observations made in this case series, we suggest the possible visual prognosis of patients with unilateral PPCD in the aspect of amblyopia development. [karger.com]

Treatment and prognosis Most patients with PPMD are asymptomatic and are diagnosed on routine eye exam. These patients usually have a great prognosis and often do not require any treatment. [webeye.ophth.uiowa.edu]

Patients who have macular dystrophy have a poor prognosis, but are unlikely to pass this dystrophy on because it is autosomal recessive. [clspectrum.com]

The pathological coexistence of PPCD and high myopia in our case is possibly due to a shared etiological pathway or genetic background. Advanced genetic analysis on similar cases is expected if more samples can be provided. [ncbi.nlm.nih.gov]

Etiology PPCD is a genetically heterogenous condition with extremely variable expression. Three genes have been implicated: VSX1 (20p11.21), COL8A2 (1p34.2-p32.3), and ZEB1 (10p11.22), but the evidence implicating VSX1 and COL8A2 is questionable. [orpha.net]

This is in contrast to other etiologies of congenital corneal clouding like Peter’s anomaly or a limbal dermoid, which can vary in size/location and often obscure underlying iris. [reviewofophthalmology.com]

An overlap with other clinical phenotypes and PPCD exists, in particular with FECD, the association being strengthened by early reports reporting mutations in the COL8A2 both in PPCD and FECD, suggesting a similar etiology [ 7 ]. [molvis.org]

Summary Epidemiology Prevalence of this form of corneal dystrophy is unknown. Clinical description Lesions generally develop in early childhood and are mostly bilateral but may be asymmetrical or unilateral in some cases. [orpha.net]

Epidemiology Frequency United States The frequency of PPMD is not well documented. Although it is considered to be uncommon, PPMD may be recognized and diagnosed more often in recent years than in the past. [emedicine.medscape.com]
