Background Fovea plana is defined as an immature macula diagnosed by OCT, showing the unusual shunt of the inner retinal layers into the fovea. The incidence of fovea plana in the adult population remains to be determined. The aim of this study was to determine the incidence of fovea plana in the French population with age-related cataract. Methods Consecutive patients who underwent cataract surgery in Rothschild Foundation Hospital, France, between January and March 2021, with preoperative analyzable OCT scans available, were retrospectively screened in order to determine the incidence of fovea plana in these population. Ophthalmological characteristics of patients were reported, and detailed. Result Fovea plana was encountered in 20 out of 204 patients during the 3 months corresponding to an incidence of 9.8%. One of those patients had stage 2 fovea plana. Conclusion Although fovea plana is defined as an immature macula, it is not rare in preoperative population. This macular aspect was not associated with poor visual acuity in our cohort.

Visual recovery after retinal detachment is often delayed despite surgical success. Changes in retinal thickness have been shown to occur after vitrectomy for retinal detachment and visual acuity seems to be related with these modifications. In this retrospective study we investigated the thickness of retinal layers using optical coherence tomography in patients successfully treated for rhegmatogenous retinal detachment between December 2014 and March 2023. We further investigated possible related clinical and demographic characteristics. A total of 1313 patients were initially identified. Of these, 1282 patients were excluded and finally 31 eyes from 31 patients were included. Twelve months after the surgical procedure the total retinal thickness, in particular, the outer nuclear layer thickness, significantly increased compared to one month postoperatively (respectively, 270.6 ± 34.2 vs. 288.0 ± 29.7, P < 0.001 and 79.5 ± 23.3 vs. 92.9 ± 16.5, P < 0.001). Factors associated with the increase were age, macula off status and the use of SF6 tamponade (all P < 0.05). No correlation was found between the increase in outer nuclear layer thicknesses and the final visual acuity in pseudophakic patients.
