Characteristics of infants with severe retinopathy of prematurity in countries with low, moderate, and high levels of development: implications for screening programs.

Objective: Retinopathy of prematurity (ROP) is a potentially avoidable cause of blindness in children. The proportion of blindness as a result of ROP varies greatly among countries depending on their level of development, being influenced by the availability of neonatal care, neonatal outcomes, and whether effective screening and treatment programs are in place. The objective of this study was to compare characteristics of premature infants who developed severe ROP between 1996 and 2002 in highly developed countries with less developed countries.

[Has the incidence of postoperative PVR in rhegmatogenous retinal detachment decreased?].

Purpose: To determine whether the incidence of severe postoperative PVR in primary rhegmatogenous retinal detachment has decreased over the last twelve years.

Materials And Methods: We prospectively evaluated 595 eyes of 554 consecutive patients with primary rhegmatogenous retinal detachment, referred before any failed attempt to reattach the retina, managed by the same surgeon between March 1983 and December 1994. The eyes were divided into two consecutive series: 275 eyes operated on from March 1983 through February 1988 (series no.

Late recurrences after successful surgery for retinal detachment with macular hole.

Six myopic eyes affected by retinal detachment with macular hole which had been successfully reattached developed recurrent retinal detachment 7-78 months postoperatively. The mean interval between surgery and the recurrent retinal detachment was 13.4 months in five eyes managed with gas tamponade and no choroidal irritation.

HLA-A29.2 subtype associated with birdshot retinochoroidopathy.

Birdshot retinochoroidopathy is strongly associated with HLA-A29. This antigen can be divided into two subtypes, A29.1 and A29.

[Spontaneous course of retinal detachment with macular hole in patients with severe myopia].

We followed-up without any treatment 17 eyes of 14 highly myopic patients affected by a retinal detachment confined to the posterior pole. The follow-up ranged from 3 to 92 months (mean follow-up: 4 years). The retinal detachment remained unchanged in 12 eyes (70.
