    BackgroundThe fellow eye of a retinal detachment is at risk of developing a retinal detachment and other visually debilitating disease.AimTo investigate the rate of bilaterality of retinal detachment (RD), the presenting visual acuity (VA), and the presence of ocular morbidity in the fellow eye of patients with RD.Patients And MethodsA multicenter, prospective, cross-sectional study examining the fellow eye of consecutive patients who were diagnosed with different types of RD. The patients were seen within one year and examined in four Nigerian eye hospitals and clinics. Demographics, VA, and clinical findings at the presentation were reported on examination of the fellow eyes.ResultsTwenty-seven (11.4%) out of 237 patients (264 eyes) had an RD in the fellow eye. The mean age of all study patients was 46.2 ± 16.8 years, M/F: 161 (67.9%)/76 (32.1%). The rates of bilaterality for rhegmatogenous, exudative, and tractional RDs were 4.2%, 11.1%, and 31.1%, respectively. Diagnosis of RD in an eye was associated with a risk of developing fellow eye rhegmatogenous retinal detachment (RRD) (P < 0.001) and tractional RD (P < 0.001), respectively. RRD in an eye was associated with a 17% risk of developing RD in the fellow eye (β = -1.6, OR = 0.202, P < 0.001). The BCVA in the fellow eye of the three types of RD varied significantly (P < 0.001). The fellow eye was blind in 25.2% of RRD, 54.1% of tractional retinal detachment (TRD), and 11.1% of exudative retinal detachment (ERD). Bilateral RD eyes were blind in RRD (85.7%), TRD (71.1%), and ERD (50%). One hundred and seven eyes (40.5%) of the total 264 RD eyes studied had other fellow eye events at the presentation.ConclusionA patient with an RD in one eye is at significant risk of developing a blinding RD in the fellow eye. This risk varies with the type of RD and is highest with TRD. However, RRD, the commonest type of RD, can benefit from prophylactic treatment to the fellow eye RD predisposing lesions.
