A cohort of 1049 individuals diagnosed with rhegmatogenous retinal detachment (RRD) were monitored over a mean duration of 5.7 ± 0.3 years.

In total, a diagnosis of bilateral sequential rhegmatogenous retinal detachment (RRD) was given to 153 patients, accounting for 14.6% of the study population during the specified follow-up period. A total of 582 fellow eyes had available OCT images.

Among these, 229 fellow eyes (39.3%) exhibited posterior vitreous detachment (PVD), while 353 fellow eyes (60.7%) showed an attached hyaloid.

An RRD was observed in seven fellow eyes, accounting for 3.1% of cases, where a posterior vitreous detachment (PVD) was present at the time of presentation.

Among the group of eyes with an attached hyaloid, a total of 28 eyes (7.9%) exhibited a retinal detachment (RRD) during the course of the study. However, when specifically considering those eyes in which a posterior vitreous detachment (PVD) occurred during the follow-up period, it was observed that 23.7% of these eyes also experienced an RRD.

During the period of PVD development in the contralateral eye, it was observed that an additional 21 eyes (17.8%) exhibited a retinal tear, which was successfully managed without subsequent progression to rhegmatogenous retinal detachment (RRD).

Findings: Optical coherence tomography (OCT) imaging of the unaffected eye at the initial diagnosis of a rhegmatogenous retinal detachment (RRD) provides valuable insights into the assessment of the risk level for RRD in that eye. Patients who exhibit a fully detached posterior hyaloid are observed to have a notably reduced risk of rhegmatogenous retinal detachment (RRD) compared to those with a visible posterior hyaloid. Consequently, individuals with a visible posterior hyaloid necessitate close monitoring during the development of posterior vitreous detachment (PVD).
