RETINA/VITREOUS PREFERRED PRACTICE PATTERN® DEVELOPMENT PROCESS AND PARTICIPANTS
The Retina/Vitreous Preferred Practice Pattern® Panel members wrote the Posterior Vitreous Detachment, Retinal Breaks, and Lattice Degeneration Preferred Practice Pattern® (PPP) guidelines. The PPP Panel members discussed and reviewed successive drafts of the document, meeting in person twice and conducting other review by e-mail discussion, to develop a consensus over the final version of the document.

OBJECTIVES OF PREFERRED PRACTICE PATTERN® GUIDELINES
As a service to its members and the public, the American Academy of Ophthalmology has developed a series of Preferred Practice Pattern® guidelines that identify characteristics and components of quality eye care. Appendix 1 describes the core criteria of quality eye care.
The Preferred Practice Pattern® guidelines are based on the best available scientific data as interpreted by panels of knowledgeable health professionals. In some instances, such as when results of carefully conducted clinical
METHODS AND KEY TO RATINGS
Preferred Practice Pattern® guidelines should be clinically relevant and specific enough to provide useful information to practitioners. Where evidence exists to support a recommendation for care, the recommendation should be given an explicit rating that shows the strength of evidence. To accomplish these aims, methods from the Scottish Intercollegiate Guideline Network1 (SIGN) and the Grading of Recommendations Assessment, Development and Evaluation2 (GRADE) group are used. GRADE is a
HIGHLIGHTED FINDINGS AND RECOMMENDATIONS FOR CARE
Acute horseshoe retinal tears and traumatic breaks usually require treatment.
Asymptomatic atrophic or operculated retinal breaks rarely need treatment. More generally, an eye that has atrophic round holes within lattice lesions, has minimal subretinal fluid without progression, or lacks evidence of posterior vitreous detachment (PVD) does not require treatment.
An early diagnosis of a retinal detachment is important because the rate of successful retinal reattachment is higher and the visual
DISEASE DEFINITION
Posterior vitreous detachment (PVD) is a separation of the posterior vitreous cortex from the internal limiting membrane of the retina.4 (See Glossary.) This separation may be complete or partial. Vitreous traction at sites of significant vitreoretinal adhesion is responsible for most retinal breaks that lead to retinal detachment. Retinal breaks are defined as full-thickness defects in the retina. Lattice degeneration is a vitreoretinal degenerative process that predisposes to retinal tears
POSTERIOR VITREOUS DETACHMENT
Population-based studies that evaluate incidence and prevalence of PVD are difficult to conduct owing to the lack of definite clinical signs and unreliable clinical tests. A PVD typically occurs between the ages of 45 and 65 in the general population with earlier onset in men than women; however, the posterior vitreous may detach earlier in trauma and myopia, or be precipitated by ophthalmic surgical procedures.5, 7, 8, 9 Posterior vitreous detachment leads to vitreous traction at the vitreous
PATIENT OUTCOME CRITERIA
For management and treatment for PVD and RRD, the following outcomes are important:
- ♦
Prevention of visual loss and functional impairment
- ♦
Maintenance of quality of life
DIAGNOSIS
The initial evaluation of a patient with risk factors for retinal detachment or symptoms of a PVD involves detection of vitreous pigment cells or debris and includes a thorough peripheral examination looking for retinal tears or holes. It also includes all aspects of the comprehensive adult medical eye evaluation,75 with
APPENDIX 1. QUALITY OF OPHTHALMIC CARE CORE CRITERIA
Providing quality care is the physician's foremost ethical obligation, and is the basis of public trust in physicians.
AMA Board of Trustees, 1986
Quality ophthalmic care is provided in a manner and with the skill that is consistent with the best interests of the patient. The discussion that follows characterizes the core elements of such care.
The ophthalmologist is first and foremost a physician. As such, the ophthalmologist demonstrates compassion and concern for the individual, and utilizes
APPENDIX 2. INTERNATIONAL STATISTICAL CLASSIFICATION OF DISEASES AND RELATED HEALTH PROBLEMS (ICD) CODES
Precursors to rhegmatogenous retinal detachment and related entities with the following ICD-9 and ICD-10 classifications (see Glossary):
Empty Cell ICD-9 CM ICD-10 CM Rhegmatogenous retinal detachment: Break, unspecified 361.00 H33.00- Break, giant 361.03 H33.03- Break, multiple 361.02 H33.02- Break, single 361.01 H33.01- Vitreous detachment/degeneration 379.21 H43.81- Retinal break without detachment: Retinal break, unspecified 361.30 H33.30- Horseshoe tear 361.32 H33.31- Multiple 361.33 H33.33- Round hole 361.31 H33.32- Multiple
GLOSSARY
Atrophic retinal breaks or holes: Full-thickness retinal defects, unrelated to vitreoretinal traction. These can occur within lattice lesions or in areas of the retina that appear otherwise normal.
Clinical retinal detachment: A retinal detachment that either impairs a portion of the visual field or extends more than 2 disc diameters posterior to the equator.
Cystic retinal tufts: Small congenital lesions of the peripheral retina. They are slightly elevated and usually whitish in color with
