Majority (44/53; 83 %) of the patients had bilateral involvement. 5/9 (44 %) patients with unilateral presentation were amblyopic in the affected eye. [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]

Descemet membrane endothelial keratoplasty with a stromal rim in the treatment of posterior polymorphous corneal dystrophy. [ijo.in]

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]

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

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]

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]

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]

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]

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]

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]

Pathophysiology Three main abnormalities are described: vesicular changes, endothelial band lesions, and irregular diffuse opacities of the posterior corneal surface involving both the Descemet membrane and the endothelium. [emedicine.medscape.com]
