best corrected visual acuity (BCVA), contrast acuity, and color vision). In order to gain a better insight in factors influencing the long term postoperative recovery of visual function after macula-off RRD, our study aimed to establish the relative contributions of a number of factors including both the duration and the height of the macular detachment to various aspects of visual recovery (i.e. Finally, follow-up periods in these studies ranged from 3 to 24 months,, ,, , –, , whereas it is known that postoperative VA can improve gradually, reaching a maximum value between 6–12 months postoperatively. ,, ,, – However, in recent years trans pars plana vitrectomy (TPPV) is often used as a primary procedure, which might affect postoperative recovery. Furthermore, previous studies relate to the outcomes for patients who have undergone “conventional” (buckling) surgery. The few studies on the influence of the height and the duration of the macular detachment on the postoperative recovery of VA, found that - within the first week of macular detachment - a lower height of macular detachment was associated with better postoperative visual acuity. ,, –, Also, such an assumption is not in line with animal experiments, in which a progressive loss of photoreceptor cells is seen already within the first week of retinal detachment, and it has been demonstrated that photoreceptor cell degeneration increases as the height of the macular detachment is increased. The absence of a relation between the duration of the macular detachment within the first week and functional recovery may be a misguided assumption, since the effect of the height of the macular detachment has not been considered in most studies. However, he and others suggested that a delay in surgical repair between 24 hours and 7 to 9 days does not preclude good functional recovery after macula-off RRD, , and should not be expected to have a significant effect on final visual outcome. Burton observed that postoperative VA was dependent on the preoperative duration of macular detachment in RRD patients. The timing of optimal surgical intervention remains inconclusive. Most studies consider only the recovery of visual acuity and lack data on other aspects of macular function such as contrast acuity and color vision. įactors that may influence functional recovery after macula-off RRD include preoperative VA, duration of macular detachment,, ,, – height of macular detachment,, , – age,, and refractive error. Permanent functional damage is particularly observed if the macula is detached, – which occurs in about 50% of cases. Contrary to the high anatomical success rate –, – the prognosis for the recovery of visual acuity (VA) may be disappointing. – The treatment modality of RRD is surgical reattachment of the retina. Rhegmatogenous retinal detachment (RRD) with an incidence of 18.9/100,000 people per year in the Netherlands is a potentially blinding ophthalmic pathology.
