No Changes in Keratometry Readings and Anterior Chamber Depth after XEN Gel Implantation in Patients with Glaucoma.

Background: This study aimed to compare keratometry and anterior chamber depth (ACD) changes after XEN implantation in primary open-angle glaucoma (POAG) cases over a 3-month follow-up period. Methods: Twenty patients with POAG who underwent XEN63 implantation, either standalone or combined with cataract surgery, were included. Preoperative data, including best-corrected visual acuity (BCVA), refraction, gonioscopy, ophthalmoscopy, intraocular pressure (IOP) evaluation, and axial length, were collected. Corneal topography and ACD measurements were assessed preoperatively and at postoperative days 1, 7, 15, 30, 60, and 90. Each patient's eye that underwent XEN surgery was included in the study group, with the fellow eye serving as a control. Results: In the study group, there was a significant decrease in IOP after XEN stent implantation at all investigated time intervals (p < 0.05). However, changes in mean ACD did not show statistically significant differences at any follow-up examination in both the study and control groups. Additionally, keratometry readings revealed no significant changes in total astigmatism or steep keratometry values in either group. Conclusions: XEN implantation in POAG cases resulted in a significant decrease in IOP over the 3-month follow-up period. However, there were no significant changes observed in mean ACD or keratometry readings, indicating stability in these parameters post-XEN implantation. These findings suggest that XEN implantation may be an effective option for IOP reduction without affecting corneal curvature or ACD in POAG patients.

Outcomes after giant peripheral retinotomy and anterior flap retinectomy for rhegmatogenous retinal detachments with advanced proliferative vitreoretinopathy using small gauge vitrectomy.

PURPOSE: To analyze the visual and anatomical outcomes for eyes with rhegmatogenous retinal detachment (RRD) and advanced proliferative vitreoretinopathy (PVR) undergoing giant peripheral retinotomy (GPR) using 25-gauge pars plana vitrectomy (PPV). METHODS: In this retrospective multi-center study, patients with RRD with either anteroposterior or circumferential retinal shortening and advanced PVR requiring more than 90-degree GPR with/without relaxing retinotomy were included. Subjects of either gender, any age group, and with complete surgical notes were included. Outcome measures of the study included anatomical success (i.e. complete retinal re-attachment) at 6 months using survival analysis, visual outcomes, and post-operative complications. RESULTS: Forty-one eyes of 41 patients (33 males) with a mean age of 44.9 ± 21.4 years were included. At 6 months follow-up, anatomical success was seen in 29 eyes (70.7%) with a cumulative re-attachment rate of 66% (95% confidence interval = 48 = 79%). All re-detachments occurred at ≤6 months with a peak at 4-6 months (n = 9). Twenty-three eyes (56%) achieved ambulatory vision (5/200) or better. Direct perfluorocarbon liquid-silicone oil exchange was performed in 20 eyes. Intra-operative complications included persistent retinal folds (2 eyes), subretinal air (1 eye), and subretinal bleed (1 eye). Eleven eyes (26.8%) developed secondary glaucoma (2 eyes required a drainage device), and hypotony of ≤6 mmHg was noted in 3 eyes (7.3%). Corneal decompensation was noted in 8 eyes (19.5%), and 3 eyes (7.3%) underwent re-surgery for re-RRD. CONCLUSION: After GPR using small gauge PPV, two-thirds achieve anatomical success, and over half have ambulatory vision, but overall post-operative complications can occur in more than half of the eyes.

POLYPOIDAL LESIONS ASSOCIATED WITH CHOROIDAL NEVI.

PURPOSE: To investigate eyes with polypoidal lesions associated with choroidal nevi, their multimodal imaging characteristics, and long clinical follow-up. METHODS: Multicenter, retrospective case series study of patients with polypoidal lesions overlying choroidal nevi. Demographic and clinical information were recorded. Multimodal imaging including color fundus photography, optical coherence tomography, optical coherence tomography angiography, fundus fluorescein angiography, indocyanine angiography, and A- and B-scan ultrasonography were analyzed for nevus and polypoidal lesion characteristics. RESULTS: Fourteen eyes (14 patients; mean age: 70.3 ± 6.7 years) with polypoidal lesions overlying choroidal nevi were included. The mean follow-up duration was 50.0 ± 27.9 months (range 12-108). All nevi were pigmented on color fundus photography, flat on ultrasonography with a mean basal diameter of 3.8 ± 0.4 mm. In all but one eye, optical coherence tomography showed a shallow irregular pigment epithelium detachment overlying the nevus. A total of 11/14 eyes (78.6%) had exudative activity, 9 eyes received intravitreal anti-vascular endothelial growth factor injections, and one eye required intravitreal anti-vascular endothelial growth factor combined with photodynamic therapy. Mean visual acuity was 20/32 at baseline and 20/50 at final visit. CONCLUSION: We present the largest known cohort of eyes with polypoidal lesions associated with choroidal nevi with up to 9 years follow-up. The exudative degree of the polypoidal lesion in this condition is variable and treatment decisions should be taken on an individual basis. We hypothesize that choroidal ischemia because of altered choroidal vasculature rather than Haller layer hyperpermeability plays a role in the formation of polypoidal lesions overlying nevi.

Effect of Intravitreal Brolucizumab in the Treatment of Polypoidal Choroidal Vasculopathy With Foveal Lipid Exudation.

A 71-year-old woman with a history of blurred vision in her right eye for nearly two months came to our attention. A complete ophthalmological evaluation, including best-corrected visual acuity measurement, fundus examination, spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography, was performed. Multimodal imaging showed the presence of a polypoidal choroidal vasculopathy (PCV) lesion surrounded by diffuse hard exudates in the macular area. Our patient received three monthly intravitreal injections of brolucizumab during the loading phase, followed by an intravitreal injection every eight weeks for a total of 48 weeks of follow-up. The therapy appeared to be effective for improving both visual and anatomical outcomes revealing an important regression of the PCV and an almost complete reabsorption of lipid exudates. Intravitreal brolucizumab could be considered an effective treatment in the management of lipid exudation in PCV patients.

Treatments for Ocular Diseases in Pregnancy and Breastfeeding: A Narrative Review.

Pregnancy is a medical condition in which the physiological changes in the maternal body and the potential impact on the developing fetus require a cautious approach in terms of drug administration. Individual treatment, a thorough assessment of the extent of the disease, and a broad knowledge of the therapeutic options and different routes of administration of ophthalmic drugs are essential to ensure the best possible results while minimizing risks. Although there are currently several routes of administration of drugs for the treatment of eye diseases, even with topical administration, there is a certain amount of systemic absorption that must be taken into account. Despite continuous developments and advances in ophthalmic drugs, no updated data are available on their safety profile in these contexts. The purpose of this review is both to summarize the current information on the safety of ophthalmic treatments during pregnancy and lactation and to provide a practical guide to the ophthalmologist for the treatment of eye diseases while minimizing harm to the developing fetus and addressing maternal health needs.

Two-port dry vitrectomy for rhegmatogenous retinal detachment: a pilot study.

OBJECTIVE: To evaluate the safety and efficacy of a new surgical technique for the management of primary rhegmatogenous retinal detachment (RRD), consisting of localized PPV near the retinal break(s), without infusion line, associated with a drainage of subretinal fluid and cryoretinopexy. METHODS: Multicentric prospective study conducted at the University Hospital of Cagliari and IRCCS Fondazione Policlinico Universitario A. Gemelli, Roma. Twenty eyes affected by RRD with the causative retinal break(s) in the superior meridians were enrolled between February 2022 and June 2022. Patients with cataract ≥3, aphakia, significant posterior capsule opacification, giant retinal tears, retinal dialysis, history of trauma and PVR ≥C2 were excluded. All eyes underwent a two-port 25-gauge PPV with localized removal of the vitreous surrounding retinal break(s), followed by 20% SF6 injection and cryopexy. The surgical time was recorded for each procedure. Best-corrected visual acuity (BCVA) was measured at baseline and postoperative 6 months. RESULTS: Primary anatomic success at 6 months was achieved by 85% of patients. No complications occurred, except for three (15%) retinal re-detachments. The average surgical time was 8.61 ± 2.16 min. Overall, the difference between pre- and last postoperative mean BCVA was statistically significant (p = 0.02). CONCLUSIONS: Two-port dry PPV demonstrated safety and efficacy for the treatment of RRD, reaching an 85% of anatomical success rate. Although further studies are necessary to confirm the efficacy and long-term benefit of this treatment, we believe that this surgical technique could be considered a valid and safe alternative for the management of primary RRD.

AMNIOTIC MEMBRANE TRANSPLANT IN A PATIENT WITH RECURRENT MACULAR HOLE AND ATROPHIC AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To report a case of a recurrent macular hole (MH) and atrophic age-related macular degeneration in a patient, treated with human amniotic membrane transplant. METHODS: Interventional case report. RESULTS: A 72-year-old man was referred to our Retina Unit for a recurrent MH associated with atrophic age-related macular degeneration. The patient was already operated for a full-thickness MH without any anatomical and functional benefit. A 25-gauge vitrectomy, under local anesthesia was performed. A human amniotic membrane patch was transplanted under the retina through a 180° retinectomy to close the MH and eventually exploit his regenerative effects on the atrophic pigment epithelium. Follow-up was taken at 1, 3, and 6 months and 1 year. No intra- or postoperative complications were recorded. At 1 month, a complete MH closure was achieved, and best-corrected visual acuity increased from 20/400 to 20/320. Unfortunately, after 1 year, the macular atrophic area increased and the best-corrected visual acuity came back to 20/400. CONCLUSION: A human amniotic membrane was used to close a MH in a patient with atrophic age-related macular degeneration, although progression of the geographic atrophy continued after MH closure.

Quantitative and Qualitative Assessments of Retinal Structure with Variable A-Scan Rate Spectralis OCT: Insights into IPL Multilaminarity.

The aim of this study was to evaluate the qualitative and quantitative differences between 20 and 85 kHz A-scan rate optical coherence tomography (OCT) images acquired by spectral domain OCT. The study included 60 healthy subjects analyzed with horizontal linear scans with a variable A-scan rate (SHIFT technology, Heidelberg Engineering, Heidelberg, Germany). The retinal thickness measurement of each retinal layer was performed in three different positions (subfoveal, nasal, and temporal). The qualitative assessment was performed by two independent observers who rated every image with a score ranging from 1 ("sufficient") to 3 ("excellent") on the basis of three parameters: visualization of the vitreo-retinal interface, characterization of the retinal layers, and visualization of the sclero-choroidal interface. No statistically significant differences in terms of retinal layer thickness between the two A-scan rate scans were observed (p > 0.05). The coefficient of variation of the retinal thickness values was lower in the 20 kHz group (25.8% versus 30.1% with the 85 kHz). The 20 kHz images showed a higher quality index for both observers. An inner plexiform layer (IPL) multilaminarity was detected in 78.3% of patients from the 20 kHz group and in 40% of patients from the 85 kHz group (p < 0.05).

Management of Accidental Intravitreal Dexamethasone Injection Into the Lens: A Case Report.

An accidental injection of a dexamethasone implant inside the crystalline lens was observed in the right eye of a 63-year-old woman suffering from a macular edema secondary to a central retinal vein occlusion. A 23-gauge pars plana vitrectomy and lensectomy followed by an intraocular lens implantation were performed to carefully remove the lens and save the whole implant in order to preserve its therapeutics effects. A strict follow-up over the following 3 months revealed an improving of macular edema and no postoperative complications. The injection of a dexamethasone implant into the lens could be effectively and successfully managed with a pars plana vitrectomy and lensectomy.

Two-Port "Dry Vitrectomy" as a New Surgical Technique for Rhegmatogenous Retinal Detachment: Focus on Macula-on Results.

We evaluated a new surgical technique for treating primary rhegmatogenous retinal detachment (RRD), consisting of localized vitrectomy near the retinal break associated with drainage of subretinal fluid without infusion. Twelve eyes of twelve patients with primary RRDs with macula-on superior, temporal, and/or nasal quadrants' RRD with retinal breaks between 8 and 4 o'clock, pseudophakic or phakic eyes, were enrolled. All eyes underwent a two-port 25-gauge vitrectomy with localized removal of the vitreous surrounding the retinal break(s), followed by a 20% SF6 injection and cryopexy. The difference between pre-operative (T0) and post-operative mean BCVA at 6 months follow-up (T6) was not statistically significant (0.16 logMAR vs. 0.21 logMAR; p = 0.055). Primary anatomic success at 6 months was achieved by 86% of patients. No other complications, except for two retinal re-detachments linked to an incorrect head position of the patients, were recorded. Although further studies are necessary to evaluate the treatment's efficacy, we believe our technique could be considered a valid alternative for managing primary RRD.

Risk Factors of Cystoid Macular Edema After Pars Plana Vitrectomy for Pseudophakic Retinal Detachment.

INTRODUCTION: This study aimed to investigate the prevalence of cystoid macular edema after pars plana vitrectomy for the treatment of pseudophakic rhegmatogenous retinal detachment and identify possible related risk factors. METHODS: A retrospective monocentric study was conducted within a cohort of pseudophakic patients undergoing vitrectomy for rhegmatogenous retinal detachment between January 2019 and December 2022. Demographic data, initial and intraoperative characteristics of rhegmatogenous retinal detachment, and postoperative data were analyzed. Cystoid macular edema was defined on optical coherence tomography exclusively. RESULTS: A total of 164 eyes of 164 patients were included for analysis. The mean age of the patients at surgery was 65.7 ± 12.0 years. The mean best-corrected visual acuity was 2.1 ± 1.0 logMAR preoperatively and 1.0 ± 0.7 logMAR postoperatively. The mean follow-up was 13.4 ± 7.7 months. The prevalence of cystoid macular edema was 17.1% [9.8-26.4]. In multivariate analysis, severe proliferative vitreoretinopathy (relative risk 3.6 [1.3-9.7]) and laser retinopexy (relative risk 8.4 [1.1-64.7]) were independently and significantly associated with cystoid macular edema. CONCLUSION: The prevalence of cystoid macular edema in pseudophakic rhegmatogenous retinal detachment after pars plana vitrectomy was 17.1%. Severe proliferative vitreoretinopathy stage and the use of endolaser retinopexy were independent risk factors for development of cystoid macular edema.

Multimodal Imaging Based Predictors for the Development of Choroidal Neovascularization in Patients with Central Serous Chorioretinopathy.

This study evaluated predictors for choroidal neovascularization (CNV) associated with central serous chorioretinopathy (CSCR) based on multimodal imaging. A retrospective multicenter chart review was conducted on 134 eyes of 132 consecutive patients with CSCR. Eyes were classified as per the multimodal imaging-based classification of CSCR at baseline into simple/complex CSCR and primary episode/recurrent/resolved CSCR. Baseline characteristics of CNV and predictors were evaluated with ANOVA. In 134 eyes with CSCR, 32.8% had CNV (n = 44) with 72.7% having complex CSCR (n = 32), 22.7% having simple (n = 10) and 4.5% having atypical (n = 2). Primary CSCR with CNV were older (58 vs. 47, p = 0.00003), with worse visual acuity (0.56 vs. 0.75, p = 0.01) and of longer duration (median 7 vs. 1, p = 0.0002) than those without CNV. Similarly, recurrent CSCR with CNV were older (61 vs. 52, p = 0.004) than those without CNV. Patients with complex CSCR were 2.72 times more likely to have CNV than patients with simple CSCR. In conclusion, CNV associated with CSCR was more likely in complex CSCR and older age of presentation. Both primary and recurrent CSCR are implicated in CNV development. Patients with complex CSCR were 2.72 times more likely to have CNV than patients with simple CSCR. Multimodal imaging-based classification of CSCR supports detailed analysis of associated CNV.

Safety and efficacy of cryopexy during pars Plana vitrectomy in rhegmatogenous retinal detachment.

PURPOSE: To evaluate efficacy and safety of intraoperative cryoretinopexy in cases of rhegmatogenous retinal detachment (RRD). METHODS: In this retrospective, interventional case series, we review the medical records of 85 consecutive cases of RRD treated with pars plana vitrectomy and gas tamponade, without the use of perfluorocarbon liquids. Baseline best-corrected visual acuity, intraocular pressure, number and location of retinal breaks, location and extension of retinal detachment, duration of symptoms, macula status, presence, and grade of proliferative vitreoretinopathy (PVR) were registered. Follow-up visits were at 1 day, 15 days, 1 month and 3 months. Anatomical and functional outcomes and any adverse event were recorded. RESULTS: Primary anatomical success was obtained in 82/85 patients (96%). During the postoperative period, PVR was observed in 4/85 cases (4.7%), 3 of whom developed recurrence of retinal detachment. 7/85 (8.2%) patients developed ocular hypertension. We built a model of logistic regression including age, sex, lens status, macula status, number of quadrants involved, number of ruptures and duration of symptoms. None of the variables considered was found to be a predictor of postoperative PVR development. Symptom's duration (ß = 0.429; 95% CI = 0.009-0.023; P < 0.001) and preoperative BCVA (ß = 0.273; 95% CI = 0.034-0.184; P = 0.005) were predictors for final BCVA. CONCLUSION: These findings emphasize the safety and efficacy of the use of intraoperative cryotherapy, associated with PPV and gas tamponade, for the management of uncomplicated RRDs.

Intravitreal Injection Planning during COVID-19 Pandemic: A Retrospective Study of Two Tertiary University Centers in Italy.

The COVID-19 pandemic has hampered the optimum management of retinal diseases. This study examined the impact of the pandemic on the intravitreal-injection practice in two academic centers in Italy along with the related medico-legal implications. A retrospective analysis of electronic medical records from 16 March 2020 to 14 March 2021 at the ophthalmological departments of University of Cagliari (SGD) and University Magna Græcia of Catanzaro (UMG) was conducted. The data collected between 16 March 2020 and 14 June 2020 (lockdown), 15 June 2020 and 13 September 2020 (unlock), and 14 September 2020 and 14 March 2021 (second wave) were compared with those of the same period of the previous year. Weekly data on the administered drug and the number and type of treated disease were collected and analyzed. During the lockdown, a drop of 59% at SGD (p < 0.00001) and 77% at UMG (p < 0.00001) in intravitreal injections was found. In the first year of the pandemic, the reduction in injections was approximately of 27% (p < 0.0008) and 38% (p < 0.0001) at SGD and UMG, respectively. The COVID-19-related containment measures and the health resources redistribution have led to a delay in the treatment of chronic diseases of the retina, prioritizing the undeferrable ones. The lack of management guidelines has conceived relevant ethical and medico-legal issues that need to be considered in future measures planning.

Imaging characteristics of bilateral CSCR cases:12 months follow up.

PURPOSE: To report the disease pattern, progression and imaging characteristics in eyes with bilateral central serous chorioretinopathy (CSCR). METHODS: This was a retrospective case review of bilateral CSCR patients with active disease in at least one eye. Multimodal imaging including fundus photography, fundus autofluorescence, optical coherence tomography (OCT), fluorescein and indocyanine angiography (FA/ICGA) was done at baseline and follow-up visits. Disease classification was done using recently described classification criteria. The degree of asymmetry in the disease distribution pattern at baseline and disease progression during follow-up visit with a minimum duration of 12 months was studied. RESULTS: Among 103 CSCR patients, 36 patients (34.95%) with mean age of 53.6 ± 10.5 years had bilateral CSCR at baseline. Five patients (13.9%) had asymmetrical disease i.e. simple in one eye and complex in fellow eye. The remaining 31 patients had symmetric disease (simple, 2; complex 29). Mean duration of follow up was 17.58 ± 13.84 months. There was no significant difference between both eye parameters at last follow up (best corrected visual acuity, BCVA; central macular thickness, CMT; and subfoveal choroidal thickness, SFCT) (all p > 0.05). At last follow up, 22 eyes (2 simple and 20 complex) remained active whereas none of the eyes converted from simple to complex CSCR. CONCLUSION: Bilateral disease was more commonly seen with complex CSCR in contrast to simple CSCR. Moreover, disease distribution in complex CSCR had symmetric pattern if bilateral disease was present. None of the simple CSCR eyes converted to complex type.

Ocular Surface Changes Associated with Face Masks in Healthcare Personnel during COVID-19 Pandemic.

The aim of this study was to investigate ocular surface changes associated with face mask (FMs) use of healthcare personnel during the COVID-19 pandemic. We prospectively evaluated 200 eyes of 100 individuals during working hours and 40 eyes of 20 individuals during their rest days as a control group. Dry eye symptoms were assessed with the Ocular Surface Disease Index (OSDI) and McMonnies questionnaire. The clinical investigation included the best corrected visual acuity (BCVA), corneal fluorescein staining (FS), break-up time (BUT), and Schirmer test I before and after a 7-h work shift with a continuative use of surgical or N95 masks. The control group was evaluated similarly twice a day, at 8:00 a.m. and at 3:00 p.m.. In the study group, BCVA, FS, BUT, and Schirmer test were investigated and there was a significant negative variation at the end of the shift. On the contrary, the control group did not show significant variations of any clinical feature. Furthermore, no significant changes in clinical parameters were observed during the use of surgical or N95 masks. In conclusion, FMs continuative use resulted in daily ocular surface modifications specifically in healthcare personnel.

Interobserver Agreement of Novel Classification of Central Serous Chorioretinopathy.

Objective To validate the newly proposed multimodal-imaging-based classification for central serous chorioretinopathy (CSCR). Methods This was a retrospective study performed in a total of 87 eyes of 44 patients with a diagnosis of CSCR. Multimodal images in the form of auto-fluorescence, fundus fluorescein angiography, indocyanine green angiography, and optical coherence tomography (OCT) images, of all the patients, were presented to two masked retina specialists. The masked observers graded each eye into simple or complex; primary, recurrent, resolved; and specific features such as foveal involvement, outer retinal atrophy, and choroidal neovascularization (CNV). Interobserver agreement was assessed using Cohen's kappa. In areas of non-consensus, a detailed discussion was carried out with a third independent grader.  Results The mean age of the 44 patients (32 males and 12 females) was 49.2±9.3 years. We found a moderate-strong agreement between the two observers in all subclassifications, that included "simple or complex" (kappa value=0.91, 95% CI 0.82-0.99, p<0.001); "primary/recurrent/resolved" (kappa value=0.88, 95% CI 0.80-0.96, p<0.001) and "foveal involvement" (kappa value=0.89,95%CI 0.8-0.98, p<0.001). However, there was less agreement between the two graders with respect to classification of "outer retinal atrophy" (kappa value=0.72, 95%CI 0.57-0.87, p<0.001) and "presence/absence of CNV" (kappa value=0.75, 95% CI 0.58-0.92, p<0.001). Non-consensus in categorizing "outer retinal atrophy" was seen in eyes with sub-retinal hyper-reflective material (SHRM) and outer nuclear layer (ONL) thinning overlying subretinal fluid, and non-consensus in categorizing "CNV" was seen in eyes with inner choroidal atrophy. Conclusion Our study reports the validity and strong interobserver agreement in several aspects of the multimodal-imaging-based classification. This could support its implementation in clinical practice and pave way for appropriate treatment guidelines.

Oral-ocular trans infection of Epstein Barr virus. A possible new way of transmission by wearing masks in the SARS-CoV-2 era.

Purpose: To describe a case of an infective vitreitis with an exudative retinal detachment in a 56-year-old lady who was previously affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Observations: A broad workup for infections including the main viruses and bacteria was performed. Salivary droplets, tear film and vitreous samples were collected, resulting positive only for Epstein-Barr virus (EBV). Viraemia and immunoglobulin M for EBV negative, whereas immunoglobulin G positive. The patient showed a simultaneous painless erosion on the right margin of the tongue that's with the lab swab demonstrated the presence of EBV at the same time the vitreitis in the left eye was present. Conclusions and Importance: Our speculation is that a continuous use of the mask, especially in immunocompromised subjects, it might create a new route for spreading infectious oral agents in the ocular area, and this case is a warning for all the ophthalmologists that have to be aware of this threatening possibility in the COVID era.

Influence of fellow eye on the diagnosis and classification of central serous chorioretinopathy.

PURPOSE: To assess the influence of fellow eye information on diagnosis and classification of central serous chorioretinopathy (CSCR) using multimodal imaging-based classification. METHODS: This was a retrospective, observational study including patients with CSCR with unilateral or bilateral involvement. Multimodal images of both eyes of each patient were compiled and presented to two masked retina specialists subdivided into three groups: (1) both eye data, (2) right eye data and (3) left eye data. The masked observers graded the CSCR as per the new CSCR classification into simple and complex CSCR in three different scenarios as subdivided above. Interobserver and intraobserver agreement was assessed using Cohen's kappa (95% confidence intervals). RESULTS: A total of 206 eyes of 103 patients with unilateral or bilateral CSCR were graded. We found a "strong" intraobserver and interobserver agreement when one eye versus both eye data was provided in terms of "simple CSCR" or "complex CSCR" (kappa value = 0.77 and 0.87, p < 0.001, and kappa value = 0.85 and 0.76, p < 0.001, respectively). Forty-three eyes (10.55%) showed discrepancy in classification between observers for individual eyes, whereas only 13 eyes (6.53%) showed discrepancy between observers when both eye data was provided. CONCLUSION: We conclude that fellow eye information was helpful in solving diagnostic dilemmas and reached 85% consensus in the diagnosis of CSCR between the observers. We found that information of fellow eyes led to a discrepancy only in 6.53% cases with 2.42% cases that had a controversial diagnosis of CSCR. Multimodal imaging-based CSCR classification provides objective approach to diagnose and classify CSCR.
