“Corneal topography is a powerful tool for the early diagnosis of PMD,” he said. While both are considered cornea ectatic disorders, PMD is characterized by slightly different cornea abnormalities, and does not plateau at around age 40 as typical for keratoconus. PMD is most commonly misdiagnosed as inferior keratoconus. Progressive eyesight deterioration can occur due to keratoconus and pellucid marginal degeneration (PMD).

#Icd 9 pellucid marginal degeneration code
We are having discussions over the correct ICD-9 code for 'Pelllucid Marginal Degeneration ' Does anyone have some suggestions for us. “Mild cases of PMD are difficult to detect with slit lamp examination alone,” Shimazaki said. 1 Hi-I work for a large Ophthalmology/Optometrist practice. Unlike keratoconus, stromal striae and iron ring are not seen in PMD cases, and physicians should be aware that acute hydrops may occur in patients with the disease. Pellucid marginal degeneration is a subtle condition that could lead to corneal ectasia following laser eye surgery. Glasses may also be used, but refractive surgery should be avoided. Crescentic lamellar keratoplasty and crescentic wedge excision can also be considered, he said.Ĭontact lenses, including gas-permeable hard, hybrid or scleral lenses, are the most common form of medical management for PMD, Shimazaki said. Collagen cross-linking may be useful for halting disease progression, as well as the use of an intracorneal ring segment or corneal transplantation. Proper management of pellucid marginal corneal degeneration (PMD) is important, Shimazaki said, and visual disturbances may develop later and continue to progress. Two case series, with 9 and 54 patients, were identified.
“There is no detailed epidemiological data, and unilateral cases constitute 25% of all patients.” Source: Adobe stock. For individuals who have pellucid marginal degeneration who receive ICRS, the evidence.
“The pathogenesis of PMD remains unclear, and no genetic cause has been found,” Jun Shimazaki, MD, PhD, said at Cornea Subspecialty Day at the American Academy of Ophthalmology meeting.
