Experiencia a largo plazo de pacientes con anomalía de Peters

Abstract

PurposeTo report the results in a series of Peters Anomaly cases, and propose management and treatment approaches according to the alterations associated with each case. Material and methodsA retrospective analysis was performed on the records of 27 patients (32 eyes) clinically diagnosed with Peters Anomaly. Each patient was subjected to different treatment modalities according to the type of Peters Anomaly, anywhere from medical follow-up clinics to a Penetrating Keratoplasty procedure (PKP). ResultsOf the 27 patients (32 eyes), 74% were male and 26% female, with 18.5% (5) being bilateral and 81.5% (22) unilateral. The mean number of years of follow-up was 10.2 years (Range: 3.5 to 18 years). The results of long-term VA correlate directly with the type of Peters Anomaly. For the total number of patients, the VA results were LogMAR 1.71 ± 1.04. The results by groups were: Type I with only medical monitoring LogMAR 0.3 ± 0, Type I with only Optical Iridectomy (OI) LogMAR 0.97 ± 0.78, Type I with PKP LogMAR 1.22 ± 0.97, Type II without a compromised posterior pole with PKP LogMAR 2.41 ± 0.80, and Type II with a compromised posterior pole with PKP LogMAR 2.56 ± 0.48. ConclusionsThe result of VA and long-term corneal failure is directly related to the type of Peters Anomaly. Patients with Type I who only required medical follow-ups had the most favourable prognosis. Patients who underwent Peripheral Iridectomy followed and patients in which PKP was performed had an inferior prognosis.
