[PMID: 37918576 DOI: 10.1016/j.survophthal.2023.10.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 10/17/2023] [Accepted: 10/23/2023] [Indexed: 11/04/2023]
Abstract
Microperimetry is an emerging technology that provides concurrent analysis of retinal structure and function by combining retinal sensitivity and fixation analysis with fundus imaging. We summarize the substantial evidence validating the evolving role of microperimetry as an adjunctive assessment of visual function in the perioperative setting. We show that microperimetry provides useful complementary information to other established imaging and functional modalities in the perioperative setting for a wide range of vitreoretinal surgical procedures, as well as in cataract and refractive surgeries. This includes preoperative uses such as prognostication of visual and anatomical outcomes, timing of surgical intervention, and assessment of patient suitability for surgery-as well as postoperative uses including quantification of visual recovery, investigation of unexplained postoperative vision loss, and informing expected long term functional outcomes.

Short-term Assessment of Subfoveal Injection of Adeno-Associated Virus-Mediated hCHM Gene Augmentation in Choroideremia Using Adaptive Optics Ophthalmoscopy. JAMA Ophthalmol 2022; 140:411-420. [PMID: 35266957 PMCID: PMC8914909 DOI: 10.1001/jamaophthalmol.2022.0158] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 01/17/2022] [Indexed: 11/14/2022]
Abstract
Importance Subretinal injection for gene augmentation in retinal degenerations forcefully detaches the neural retina from the retinal pigment epithelium, potentially damaging photoreceptors and/or retinal pigment epithelium cells. Objective To use adaptive optics scanning light ophthalmoscopy (AOSLO) to assess the short-term integrity of the cone mosaic following subretinal injections of adeno-associated virus vector designed to deliver a functional version of the CHM gene (AAV2-hCHM) in patients with choroideremia. Design, Setting, and Participants This longitudinal case series study enrolled adult patients with choroideremia from February 2015 to January 2016 in the US. To be included in the study, study participants must have received uniocular subfoveal injections of low-dose (5 × 1010 vector genome per eye) or high-dose (1 × 1011 vector genome per eye) AAV2-hCHM. Analysis began February 2015. Main Outcomes and Measures The macular regions of both eyes were imaged before and 1 month after injection using a custom-built multimodal AOSLO. Postinjection cone inner segment mosaics were compared with preinjection mosaics at multiple regions of interest. Colocalized spectral-domain optical coherence tomography and dark-adapted cone sensitivity was also acquired at each time point. Results Nine study participants ranged in age from 26 to 50 years at the time of enrollment, and all were White men. Postinjection AOSLO images showed preservation of the cone mosaic in all 9 AAV2-hCHM-injected eyes. Mosaics appeared intact and contiguous 1 month postinjection, with the exception of foveal disruption in 1 patient. Optical coherence tomography showed foveal cone outer segment shortening postinjection. Cone-mediated sensitivities were unchanged in 8 of 9 injected and 9 of 9 uninjected eyes. One participant showed acute loss of foveal optical coherence tomography cone outer segment-related signals along with cone sensitivity loss that colocalized with disruption of the mosaic on AOSLO. Conclusions and Relevance Integrity of the cone mosaic is maintained following subretinal delivery of AAV2-hCHM, providing strong evidence in support of the safety of the injections. Minor foveal thinning observed following surgery corresponds with short-term cone outer segment shortening rather than cone cell loss. Foveal cone loss in 1 participant raises the possibility of individual vulnerability to the subretinal injection.

Longitudinal Assessment of Ellipsoid Zone Recovery Using En Face Optical Coherence Tomography After Retinal Detachment Repair. Am J Ophthalmol 2022; 236:212-220. [PMID: 34695399 DOI: 10.1016/j.ajo.2021.10.012] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 10/03/2021] [Accepted: 10/12/2021] [Indexed: 11/01/2022]
Abstract
PURPOSE Suboptimal functional outcomes after rhegmatogenous retinal detachment (RRD) repair may be related to photoreceptor abnormalities, including alterations of the ellipsoid zone (EZ) that may not be apparent on cross-sectional optical coherence tomography (OCT). This study assessed EZ recovery using en face OCT after RRD repair and its association with visual acuity. DESIGN Post hoc analysis of a randomized controlled trial. METHODS Patients with macula-off RRD were monitored at 3, 6, 12, and 24 months postoperatively and annually thereafter. En face OCT of the EZ slab were analyzed. Hyporeflective areas were colocalized with EZ abnormalities on cross-sectional OCT B-scans and measured by 2 masked graders. Primary outcome was change in area of EZ hyporeflectivity from 3 to 24 months, and its association with Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity recovery was also assessed. RESULTS In total, 271 images of 61 patients were assessed. Mean area of hyporeflectivity significantly decreased from 3 to 24 months (-2.98 mm2; 95% CI, 1.82-4.13 mm2; P < .0001), with further reductions up to 4 years. Linear regression revealed an association between change in hyporeflective area and change in the ETDRS letter score from 3 to 24 months (β = -0.31, P = .009, R2 = 14.8%) and between duration of macula-off and change in hyporeflective area from 3 to 24 months (β = -0.37, P = .018, R2 = 13.7%). CONCLUSIONS En face OCT provides a novel biomarker for visualizing and quantifying EZ recovery after RRD repair that is associated with ETDRS visual acuity recovery. A steady decline in the area of EZ hyporeflectivity was observed over many years with delayed recovery in patients with longer duration of macula-off.

Characteristics of spontaneous reattachment of rhegmatogenous retinal detachment: optical coherence tomography features and follow-up outcomes. Graefes Arch Clin Exp Ophthalmol 2021; 259:3703-3710. [PMID: 34244825 DOI: 10.1007/s00417-021-05304-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/06/2021] [Accepted: 06/29/2021] [Indexed: 10/20/2022] Open
Abstract
PURPOSE To investigate the clinical features of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD) with diffuse retinal pigmentary changes. METHODS This retrospective study included patients diagnosed with SRRRD. The diagnosis of SRRRD was made based on characteristic fundus findings, such as diffuse retinal pigmentary clumpings, retinal pigmentary atrophy, and convex lesion margins. The clinical features of SRRRD were also evaluated. In addition, optical coherence tomography (OCT) images and follow-up data were analyzed. RESULTS Twenty patients were included in the study. All the patients showed unilateral involvement. SRRRD predominantly involved the inferior or temporal retina (90.0%). On OCT, severe disruption of the outer retinal layers was noted in the region of SRRRD. A subretinal gliosis band was noted in 11 patients (55.0%), and an epiretinal membrane (ERM) was noted in nine patients (45.0%). In 18 patients, a mean follow-up of 24.9 ± 29.2 months was performed. During the follow-up period, no definite retinal changes were noted on fundus examination or OCT. CONCLUSIONS SRRRD usually involves the inferior or temporal retina. Although severe disruption of the retinal microstructure is noted in the involved region, the condition is likely to be stable. However, long-term follow-up is required to identify progression of the ERM.

Abstract
PURPOSE This study used spectral domain-optical coherence tomography (SD-OCT) to evaluate individual retinal layer thickness in eyes with macula-off rhegmatogenous retinal detachment (RRD) treated with silicone oil (SiO) or gas endotamponades. STUDY DESIGN This was a retrospective, interventional, comparative study. METHODS The study included 86 eyes of 43 patients who were divided into 3 groups according to endotamponades: SiO, perfluoropropane (C3F8), and sulfur hexafluoride (SF6). The affected eyes were compared with the fellow eyes of the same patient via SD-OCT automated segmentation analysis. Patients with a follow-up of at least 6 months were included in the final analysis. Macular segmentation including the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), retinal pigment epithelium (RPE), inner retinal layers (IRLs), and outer retinal layers (ORLs) was analyzed. RESULTS In the SiO group, the mean thickness of each retinal layer including the RNFL, GCL, IPL, ONL, and IRLs within a 1-mm ETDRS subfield of the affected eyes was significantly lower than that of the fellow eyes (P = 0.036, P = 0.028, P = 0.003, P < 0.001, P = 0.013, respectively). There was no significant difference in the C3F8 and SF6 groups (all P > 0.05). The difference between the ONL and IRLs in the SiO-treated eyes differed significantly from that of the gas groups (P = 0.001 and P = 0.045, respectively) The difference in the GCL thickness of the affected eyes and healthy eyes showed a significant correlation with postoperative BCVA changes in the SiO, C3F8, and SF6 groups (P = 0.041, P = 0.048, and P = 0.045, respectively). CONCLUSION The findings of our study show that endotamponades used in RRD surgery may have different effects on retinal layers. In addition, SiO may cause undesirable effects on the retinal layers.

Abstract
This retrospective study investigated foveal and perifoveal retinal sensitivities using microperimetry before and after surgery for rhegmatogenous retinal detachment (RRD). Consecutive patients with RRD who underwent vitrectomy or scleral buckling were included. Comprehensive ophthalmological examinations, including microperimetry and swept-source optical coherence tomography, were performed before and 6 months after surgery. Pre- and postoperative retinal sensitivities at the fovea and 4 perifoveal measurement points farthest from the fixation point, both vertically and horizontally (superior, inferior, nasal, and temporal) were examined. A total of 34 foveal and 136 perifoveal measurement points in 34 eyes of 34 patients were evaluated. The postoperative retinal sensitivity was significantly higher than the preoperative value at foveal and perifoveal points with (P < 0.001 for both) and without (fovea: P = 0.005, perifovea: P < 0.001) RRD. The postoperative retinal sensitivity was significantly lower at foveal (P < 0.01) and perifoveal (P < 0.001) points with preoperative RRD than at points without preoperative RRD; furthermore, it was significantly better at points with ellipsoid zone (Ez) continuity than at points with Ez discontinuity (fovea: P < 0.01, perifovea: P < 0.001). RRD deteriorates retinal sensitivity, regardless of its presence or absence at the measurement point before surgery. Postoperative Ez continuity is important for good postoperative retinal sensitivity.

Abstract
AIM To provide a detailed description of the natural history of persistent subretinal fluid (SRF) after successful repair of rhegmatogenous retinal detachment (RRD) and its association with visual outcome. METHODS This was a prospective long-term follow-up for eyes undergoing scleral buckling (SB) surgery for macula-off RRD. Examinations were carried out preoperatively and postoperatively at 1, 3, 6, 9 and 12mo, until persistent SRF had completely resolved. One month postoperatively, optical coherence tomography (OCT) was used to classify SRF into three patterns: bleb-like loculated (BL), shallow-diffused (SD), and multiple blebs (MB). Serial OCT imaging was used to evaluate morphological changes in SRF until its complete disappearance. Patients were divided into two groups depending on the presence or absence of persistent SRF. RESULTS A total of 59 patients (59 eyes) were included. There were no statistical differences between two groups at baseline, except for the proportion of patients with high myopia and a younger age. One month after surgery, OCT detected persistent SRF in 49 eyes (83.1%). The 3 morphological patterns of SRF were observed in 27 eyes (55.1%) with BL, 13 eyes (26.5%) with SD, and 9 eyes (18.4%) with MB. The mean time for complete absorption differed significantly across the three SRF patterns (F=8.097, P=0.001), which was 8.8±6.1, 20.1±12.1, and 16.7±10.2mo in BL, SD, and MB, respectively. In 9 of the 13 eyes with SD, the pattern transformed into MB type. In cases involving MB, the size and number of blebs decreased gradually until they had been completely absorbed. Eyes with persistent SRF were more likely to demonstrate disruption of the ellipsoid zone (49.0% vs 10%, P=0.034). The final best-corrected visual acuity of two groups was 0.37±0.11 (with SRF) vs 0.34±0.12 (without SRF) logMAR (P=0.499), respectively. CONCLUSION High preoperative myopia and younger age are associated with persistent SRF. BL is the most commonly observed pattern with the shortest duration and gradually disappeared. Most cases involving SD SRF transform into MB type during resolution. The size and number of the MBs decrease gradually until they were completely absorbed. The absence of persistent SRF may contribute to slow visual recovery in the short-term but does not influence the final visual outcome.

Abstract
PURPOSE Limited information is available on morphologic and functional regeneration of photoreceptors after retinal detachment (RD) surgery. This observational clinical study compared morphologic and functional changes of cones after vitrectomy for macula-off retinal detachment. DESIGN Prospective, fellow-eye comparative case series. METHODS StudyPopulation: Five eyes after vitrectomy with gas for macula-off retinal detachment (retinal detachment eyes, RDE) and 5 healthy fellow eyes (HFE) of 5 patients (mean age 59.8 years, macula-off duration 0.5 days to 5.5 days). ObservationProcedures: Eyes were examined with adaptive-optics optical coherence tomography (AO-OCT), spectral-domain OCT (SDOCT), and microperimetry (MP) at 6 (baseline, BL) and 56 weeks (follow-up, FUP) after 23 gauge pars plana vitrectomy and SF6 gas tamponade. Eight corresponding regions at foveal eccentricities of 2.5° (ecc 2.5°) and 6.5° (ecc 6.5°) were analyzed in every eye. AO-OCT en face images and SD-OCT B-scans were graded regarding irregularity and loss of photoreceptor signals ranging from none to severe changes. The number of detectable cones at height of the inner-outer segment junction (IS/OS) and cone outer segment tips (COST) was counted manually in AO-OCT images. MP with a custom grid was used to assess retinal sensitivity at these locations. MainOutcomeMeasures: Cone density, cone pattern regularity and signal attenuation, retinal sensitivity. RESULTS In comparison to HFE, RDE showed highly irregular cone patterns in AO-OCT and irregular outer retinal bands in SDOCT. Despite significant improvement of cone pattern regularity compared to BL (P < .001), 63% of AO images showed remaining cone pattern irregularity and 45.5% of SDOCT B-scans showed severe signal reduction at FUP. In HFE, mean cone density retrieved from IS/OS and COST remained around 20,000/mm2 (ecc 2.5°) and 16,000/mm2 (ecc 6.5°) at BL and FUP. Cone density of RDE was significantly reduced and ranged between 200/mm2 and 15,600/mm2 (P < .001) at BL. Despite improvement at FUP (P < .001), mean cone density at IS/OS and COST was still lower compared to HFE and ranged between 7790 and 9555 cones/mm2 (P < .001). Mean retinal sensitivity of all measured locations remained 18 dB in HFE and was significantly lower in RDE, with 14.30 dB at BL and 14.64 dB at FUP. Both SDOCT grading and microperimetry sensitivity showed strong correlation with AO-OCT grading and cone density (rho values > 0.750). CONCLUSIONS The combination of AO-OCT, SDOCT, and microperimetry is a powerful tool to capture cone regeneration after vitreoretinal surgery. Our study shows that cone morphology and function improve within 56 weeks after RD surgery but structural and functional impairment is still present.

Abstract
PURPOSE To quantify changes in photoreceptor density using adaptive optics fundus camera in patients after retinal detachment (RD) and to correlate them with macular involvement and best-corrected visual acuity. METHODS At 1 and 3 months (M1 and M3) after vitrectomy, 194 patients underwent adaptive optics imagery in both eyes, at 5 locations, that we matched between time points using anatomical landmarks. Twenty-two patients (10 fovea-OFF [OFF] and 12 fovea-ON [ON]) had matched and analyzable adaptive optics images. We used analysis of variance for repeated measures. RESULTS Best-corrected visual acuity (logarithm of the minimum angle of resolution and Snellen equivalent [SE]) was significantly different between OFF and ON RDs at baseline: 2.0 (2.3-0.95) (SE: 20/2000) versus 0 (0.1-0) (SE: 20/20); at M1: 0.35 (0.5-0.1) (SE: 20/40) versus 0.05 (0-0.1) (SE: 20/25); and at M3: 0.25 (0.3-0.1) (SE: 20/32) versus 0 (0-0) (SE: 20/20). We observed that cone density was stable in fellow eyes between M1 and M3 (P = 0.67); decreased in treated eyes than in fellow eyes (P < 0.05); and increased postoperatively in the ON group (P = 0.02) but not in the OFF group (P = 0.97). Visual acuity and RD type were independently correlated with cone density (P = 0.004, P = 0.000). CONCLUSION Postoperative cone density was reduced in OFF RD, but also in the ON group, although the drop recovered during the 3-month follow-up. Cone density was significantly correlated with both visual acuity and type of RD at both time points.

Abstract
PURPOSE To evaluate the impact of restoration of foveal bulge (FB) in optical coherence tomography (OCT) images on visual acuity after resolution of diabetic macular edema with coexisting serous retinal detachment (SRD-DME). METHODS A total of 52 eyes with resolved SRD-DME and an intact ellipsoid zone at the central fovea were included. All eyes underwent best-corrected visual acuity (BCVA) examination and OCT scanning at baseline and follow-up visits (1, 3, and 6 months). The eyes were divided into two groups according to the presence of FB at 6 months. BCVA, central foveal thickness (CFT), height of SRD (SRDH), outer nuclear layer (ONL) thickness, photoreceptor inner segment (PIS), and outer segment (POS) length were compared between the two groups. RESULTS A FB was found in 25 of 52 (48%) eyes at 6 months. The FB (+) group had lower SRDH at baseline, and better BCVA, longer POS length at 6 months (all P < 0.05). There was no significant difference in the CFT, ONL thickness, and PIS length at 6 months between the two groups (all P > 0.05). More eyes in the FB (+) group had complete SRD resolution at 1 month (P = 0.009) and 3 months (P = 0.012). Eyes with complete SRD resolution at 1 month (P = 0.009) or 3 months (P = 0.012) were more likely to have a FB at 6 months. CONCLUSIONS The Presence of the FB is associated with better BCVA after resolution of SRD-DME. Eyes with lower baseline SRDH or faster SRD resolution are more likely to have a FB at 6 months.

Abstract
Purpose: To evaluate the functional and morphological outcomes of patients with SO tamponade due to primary rhegmatogenous retinal detachment (primRD) and recurrent rhegmatogenous detachment (recRD).Methods: Seventy-five eyes were enrolled in this prospective study between January 2009 and December 2016. Patients with primRD and recRD were evaluated in a complete ophthalmic examination including best-corrected visual acuity (BCVA) and OCT before and after silicone oil removal (SOR).Results: The primRD group comprised 35 eyes and the recRD group 40 eyes with a duration of SO tamponade of 9 ± 4/12 ± 11 months in the primRD/recRD groups (p = .088). The preoperative OCT revealed a high rate of morphological changes such as ERM (primRD: 24%; recRD: 69%) and CME (primRD: 10%; recRD: 55%) in the recRD compared with the primRD group (ERM: p = .18; CME: p = .04). No such difference was observed postoperatively. Disruption of the ellipsoid zone (EZ) was similar in both groups (primRD: 52%; recRD: 72%) before SOR and was restored in 66%/58% (primRD/recRD) after SOR. No difference was found regarding pre- and postoperative VA (0.91 ± 0.54/0.90 ± 0.54logMAR primRD/recRD preoperative; 0.76 ± 0.56/0.71 ± 0.53logMAR primRD/recRD at the last follow-up; p = .96/p = .70). EZ integrity (0.43 ± 0.31logMAR) was associated with better functional results than an interrupted EZ (0.86 ± 0.43logMAR; p < .001). A significant positive correlation of the duration of SO tamponade and the final VA was found in the primRD (r = 0.396, p = .02) whereas none in the recRD group (r = 0.196; p = .31).Conclusion: Morphological changes including ERM and CME were more pronounced in the recRD group, but only before SOR. Interestingly, the pre- and postoperative BCVA were similar in both groups with EZ integrity being a factor of good functional outcome. The duration of SO tamponade had a statistically significant negative impact on the postoperative VA in the primary detachments.

Br J Ophthalmol 2019; 104:660-665. [PMID: 31462417 DOI: 10.1136/bjophthalmol-2019-314236] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 07/22/2019] [Accepted: 08/12/2019] [Indexed: 11/04/2022]
Abstract
PURPOSE To report the prevalence of outer retinal layer (ORL) damage after macula-off rhegmatogenous retinal detachment (RRD) surgery and to determine its associated preoperative risk factors. METHODS 253 eyes successfully operated for macula-off RRD were included in the study. The integrity of the external limiting membrane (ELM), ellipsoid zone (EZ) and cone interdigitation zone (CIZ) of the photoreceptors was assessed at 1 month and 6 months using spectral-domain optical coherence tomography. Risk factors were analysed using univariate and multivariate logistic regression. The correlation between ORL integrity and visual outcomes was also evaluated. RESULTS CIZ, EZ and ELM defects were found in, respectively, 198 (93.4%) eyes, 100 (47.2%) eyes, 64 (30.2%) eyes at 1 month and in 160 (63.2%) eyes, 44 (17.4%) eyes and 18 (7.1%) eyes at 6 months. In multivariate analysis, duration of macular detachment was the only factor associated with ORL damage at 6 months (p=0.007). Best-corrected visual acuity significantly improved from 0.5±0.3 at 1 month to 0.3±0.3 logarithm of minimal angle of resolution at 6 months (p<0.001) and was strongly correlated with the number of affected bands (p<0.001). CONCLUSION Prevalence of outer retinal band defects substantially decreased through the study period, confirming the ability of photoreceptors to recover over time. However, shorter interval to surgery and better visual outcomes were significantly associated with fewer defects within the ORL at 6 months. These findings suggest that earlier surgery may limit RRD-associated photoreceptor degeneration and improve the patient's visual prognosis.

Abstract
Purpose: To evaluate the correlation between the retinal nerve fiber layer (RNFL), particularly the temporal RNFL (TRNFL), and visual outcomes following surgery for rhegmatogenous retinal detachment (RRD). Methods: This retrospective study was performed at a tertiary center; 32 patients underwent single and successful vitrectomy for total RRD using silicone oil as tamponade. Data were collected after oil removal. RNFL thickness and central foveal thickness (CFT) were measured using spectral domain optical coherence tomography. RNFL thickness and CFT of normal eyes were acquired as a control to calculate percentage changes in the affected eyes. The correlation between postoperative best-corrected visual acuity (BCVA) and TRNFL changes was the primary outcome measure. Results: Postoperative BCVA correlated negatively with retinal detachment (RD) duration (Pearson coefficient 0.56, P = 0.001) and percentage loss in TRNFL thickness (Pearson Coefficient 0.41, P = 0.02). The macula lost the maximum RNFL thickness (26%). The mean percentage loss of TRNFL was significantly higher in patients with postoperative BCVA <6/60 (42.63% vs. 24.06%, P = 0.009). Patients with postoperative BCVA <6/60 had a significantly longer mean RD duration (29 days) than those with postoperative BCVA >6/60 (17.5 days) (P = 0.026). Conclusion: When eyes with RRD are successfully repaired using silicone oil tamponade, the thickness of the RNFL decreases, particularly in the macula, and less macular neuronal loss is associated with better visual outcomes.

Abstract
PURPOSE To investigate retinal thickness in the central and parafoveal subfields, including segmented analysis of the inner and outer retinal layers, after vitrectomy for macula-off rhegmatogenous retinal detachment (RRD) repair. METHODS Twenty-four eyes of 24 patients who underwent primary vitrectomy for macula-off RRD repair were enrolled in this study. Spectral-domain optical coherence tomography examination and best-corrected visual acuity (BCVA) measurements were performed at 1, 3, and 6 months after vitrectomy. RESULTS At 1, 3, and 6 months after vitrectomy, retinal thickness in the temporal parafoveal subfield was more significantly (P = 0.004, 0.001, and 0.003, respectively) correlated with BCVA than the central subfield (P = 0.014, 0.001, and 0.022, respectively). Segmented analysis showed significant correlations between the retinal thickness of both the outer layer (P = 0.018, 0.030, and 0.018, respectively) and the inner layer (P = 0.003, 0.002, and 0.001, respectively) in the temporal parafoveal subfield and BCVA at every time point after vitrectomy. CONCLUSIONS These results suggest that retinal thickness in the temporal parafoveal subfield may most closely reflect postoperative BCVA after macula-off RRD repair.

Abstract
PURPOSE To investigate whether postoperative light sensitivity recovers completely to the level prior to the development of rhegmatogenous retinal detachment (RRD) after successful surgery. METHODS We retrospectively studied 44 eyes of 44 patients with RRD who were successfully operated and who underwent Humphrey central 30-2 perimetry postoperatively. The averaged total deviation in Humphrey perimetry in the reattached retina was compared with that of the horizontal or vertical counterpart in the preoperatively non-detached retina. RESULTS The averaged total deviation in the reattached retina was significantly lower than in its counterpart (p < 0.0001). The averaged residual loss of light sensitivity did not correlate with postoperative visual acuity (p = 0.8047) or with its change (p = 0.1242). CONCLUSIONS Light sensitivity in the detached retina in eyes with RRD does not completely recover after successful surgery.

Abstract
PURPOSE To investigate the incidence and natural history of persistent subfoveolar fluid (PSF) following surgery for macular off rhegmatogenous retinal detachment and the effect of PSF on photoreceptor structure and final visual acuity. METHODS Retrospective study of 61 cases with post-operative optical coherence tomography (OCT) performed within 12 weeks of surgery. Based on aetiology, cases were categorized into tractional retinal tears (TRT) group or atrophic round holes and dialyses (RHD) group to investigate the incidence and duration of PSF. A Kaplan-Meier graph was plotted to compare survival time of subfoveolar fluid for both groups. Following secondary reclassification of cases into those with and without PSF, the effect of PSF on final visual acuity and photoreceptor structure was investigated with Mann-Whitney U-test used for comparison. Spearman's correlation testing was used to probe associations between time to recorded resolution of PSF with final visual acuity and photoreceptor structure. RESULTS Incidence of PSF was greater in the RHD group and persisted for longer compared with TRT group. No detectable adverse effect of PSF on final visual acuity was seen however an individual case of severe photoreceptor atrophy was observed. No significant correlation was found between the time to recorded resolution of PSF and the final visual acuity or to photoreceptor grading scores. CONCLUSIONS A difference in incidence of PSF was detected between the aetiological groups. PSF was ubiquitous and slow to resolve in the RHD group. Most cases of PSF resolve without adverse sequelae; however, progressive photoreceptor atrophy and sub-optimal visual outcome may result in a minority.

Abstract
Spectral-domain optical coherence tomography (SD-OCT) often reveals prominent outer retinal changes after macula-off rhegmatogenous retinal detachment. Two patients who presented with macula-off retinal detachment underwent surgical repair. Initial postoperative visual acuity was 20/200 in both cases and correlated with a disruption of the central inner segment ellipsoid layer on SD-OCT. On extended follow-up, SD-OCT demonstrated restoration of the inner segment ellipsoid layer in both patients with concurrent improved visual acuity.

Abstract
Purpose. To evaluate the spatial distribution of photoreceptor inner and outer segment junction (IS/OS) reflectivity changes after successful vitrectomy for macula-off retinal detachment (PPV-mOFF) using spectral domain optical coherence tomography (SdOCT). Methods. Twenty eyes after successful PPV-mOFF were included in the study. During a mean follow-up period of 15.3 months, SdOCT was performed four times. To evaluate the IS/OS reflectivity a four-grade scale was used. Results. At the first follow-up visit the IS/OS had very similar reflectivity in entire length of the central scan with total average value of 1,05. At the second visit the most significant increase of the reflectivity was observed in temporal and nasal parafovea with average values of 2,17 and 2,22, respectively. The third region of increased reflectivity of an average value of 2,33 appeared during the third follow-up visit and was located in the foveola. At the last follow-up visit in entire central cross section the IS/OS reflectivity exceeded grade 2 reaching the highest average values in nasal and temporal parafovea and foveola. Conclusions. A gradual increase of the IS/OS reflectivity was observed in eyes after PPV-mOFF. The process is not random and starts independently in the peripheral and central part of the macula which may be attributed to the variable regenerative potential of cones and rods.

Abstract
PURPOSE The aim of the study was to analyse macular changes after rhegmatogenous retinal detachment (RRD) repair using spectral-domain optical coherence tomography (SD-OCT). METHODS Forty eyes with macula-on and 27 eyes with macula-off RRD underwent scleral buckling or vitrectomy and were postoperatively imaged using 2 SD-OCT devices (Cirrus® HD-OCT, RTVue-100®). Measurement of total and inner macular thickness consisting of ganglion cell layer + inner plexiform layer (GCL-IPL) using Cirrus or retinal nerve fibre layer + ganglion cell layer + inner plexiform layer (RNFL-GCL-IPL) using RTVue was performed. Results of inner macular thickness were compared with image results of 40 healthy controls. Qualitative analysis of inner and outer retinal layers was additionally assessed. RESULTS Measurement of overall retinal thickness within the 9 ETDRS sectors was highly correlated between both OCTs (Pearson's r, range 0.88-0.99; p < 0.001). Correlation of RNFL-GCL-IPL complex between OCTs was excellent in both surgery groups (Pearson's r, range 0.73-0.88; p < 0.001) and normal controls (Pearson's r, range 0.79-0.90; p < 0.001). The RNFL-GCL-IPL complex was thicker in both surgery groups compared to normal controls using Cirrus. Outer retinal findings of macula-off patients were seen in four eyes (14.8 %). Visual acuity (VA) significantly improved in both groups independent of preoperative VA or duration of symptoms. CONCLUSION Agreement between both OCTs was excellent for overall and inner retinal thickness, although RTVue measured a thicker RNFL-GCL-IPL complex. Thinning of inner retinal layers as a potential cause of poor VA was rarely detected, possibly due to tractional changes at the vitreomacular interface. VA improved even in patients with macula-involving RRD.
