Abstract
PURPOSE To describe the different types of vitreomacular interface abnormalities (VMIA) seen on optical coherence tomography (OCT) in type 2 macular telangiectasia (MacTel) and explain the possible reasons for its development. METHODS In this retrospective cross-sectional study, type 2 MacTel eyes with macular volumetric OCT imaging protocol were included to identify different types of VMIA such as abnormal PVD, vitreomacular traction (VMT), ERM, and lamellar and full-thickness macular hole. The VMIA findings were then correlated with different MacTel disease stages and visual acuity. RESULTS One thousand forty-three OCTs of 332 type 2 MacTel eyes from 169 patients at different visits were examined. VMIA was detected in 709 (68%) of those OCT scans in 216 (65%) eyes. There were 273 (39%), 31 (4%), 89 (13%), 7 (1%), and 381 (54%) OCT scans with vitreomacular adhesion, VMT, ERM, and inner and outer lamellar macular holes discovered respectively. VMIA eyes had a high frequency of abnormal PVD (p = 0.001) and retinal pigment clumps (RPCs) [p = 0.032]. Eyes with abnormal PVD (p = 0.034) and RPC (p = 0.000) had a higher rate of ERM development. RPC was linked to an increased risk of developing ERM (odd ratio 2.472; 95% CI 1.488-4.052). RPC and ERM contributed significantly to poor visual acuity (0.661 ± 0.416, 20/92). CONCLUSION OCT reveals a high frequency of VMIA in advanced type 2 MacTel eyes. RPC could be responsible for the development of anomalous PVD, as well as subsequent VMIAs and ERM. Additional work is required to examine the long-term changes and surgical outcomes of these eyes.

Int Ophthalmol 2024; 44:93. [PMID: 38367121 PMCID: PMC10874323 DOI: 10.1007/s10792-024-02958-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 12/04/2023] [Indexed: 02/19/2024]
Abstract
BACKGROUND The most common retinal complications after glaucoma surgery are choroidal detachment, hypotony maculopathy, malignant glaucoma, vitreous hemorrhage, endophthalmitis and retinal detachment. However, if glaucoma surgery is a risk factor for the ERM development needs to be clarified. This study aims to assess the incidence of epiretinal membrane (ERM) in 2 years of follow-up in patients with primary open-angle glaucoma (POAG) treated with Ex-Press shunt implant. METHODS A prospective, consecutive, single-center, case-control study. We enrolled patients affected by POAG and scheduled for Ex-Press device implant with or without concomitant cataract surgery. The control group was the contralateral eyes which continues anti-glaucomatous eyedrops. Complete ophthalmologic evaluation and spectral-domain optical coherence tomography were performed before surgery, at 6 months and 24 months of follow-up. RESULTS Eighty-two eyes of 41 consecutive patients, 18 males and 23 females with a mean age of 70, 29 ± 8,45, were analyzed at 24 months. 39.1% of eyes developed ERM: 29.3% were cellophane macular reflex (CMR) and 9.8% were pre-macular fibrosis (PMF). In the control group, 19.5% of eyes developed ERM: 17.1% were CMR and 2.4% were PMF. No statistically significant difference was reported (p = 0.121) between treated and control group. ERM development did not affect significantly the central foveal thickness (260.13 ± 35.01 μm at baseline, 265.03 ± 34.90 μm at 6 months and 275.18 ± 33.31 μm at 24 months) and macular volume (7.75 ± 0.43 mm3 at baseline, 7.77 ± 0.48 mm3 at 6 months and 7.77 ± 0.46 mm3 at 24 months), remained comparable to reported average measures in healthy individuals during the follow-up. Concomitant cataract surgery did not increase the ERM incidence. CONCLUSION Ex-Press implant may increase the ERM incidence regardless concomitant cataract surgery, accelerating or inducing a posterior vitreous detachment, such as other ocular surgical procedure. Nevertheless, the vast majority of ERM are CMR, not affecting the macular profile.

Vitreomacular interface abnormalities in the Ghanaian African. Eye (Lond) 2024; 38:578-584. [PMID: 37773435 PMCID: PMC10858261 DOI: 10.1038/s41433-023-02737-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 09/05/2023] [Accepted: 09/07/2023] [Indexed: 10/01/2023] Open
Abstract
BACKGROUND/OBJECTIVE Describe vitreomacular interface abnormalities (VMIA) using spectral-domain optical coherence tomography (SD-OCT), and correlations with age-related macular degeneration (AMD) grade in Ghanaian Africans. SUBJECTS/METHODS Prospective, cross-sectional study of adults aged ≥50 years recruited in Ghana AMD Study. Participant demographics, medical histories, ophthalmic examination, digital colour fundus photography (CFP) were obtained. High-resolution five-line raster OCT, Macular Cube 512 × 128 scans, and additional line scans in areas of clinical abnormality, were acquired. SD-OCT VMI features classified by International Vitreomacular Traction Study Group system and relationships to AMD grade were evaluated. OUTCOMES VMIA prevalence, posterior vitreous detachment (PVD), vitreomacular adhesions (VMA), vitreomacular traction (VMT), epiretinal membranes (ERM), correlations with AMD grade. RESULTS The full Ghana AMD cohort included 718 participants; 624 participants (1248 eyes) aged ≥50 years (range = 50-101, mean = 68.8), 68.9% female were included in this analysis. CFP with OCT scans were available for 776 eyes (397 participants); 707 (91.1%) had gradable CFP and OCT scans for both AMD and VMI grading forming the dataset for this report. PVD was absent in 504 (71.3%); partial and complete PVD occurred in 16.7% and 12.0% respectively. PVD did not increase with age (p = 0.720). VMIA without traction and macular holes were observed in 12.2% of eyes; 87.8% had no abnormalities. VMIA was not significantly correlated with AMD grade (p = 0.819). CONCLUSIONS This provides the first assessment of VMIA in Ghanaian Africans. VMIA are common in Africans; PVD may be less common than in Caucasians. There was no significant association of AMD grade with VMIA.

Abstract
Purpose: To report outcomes in terms of efficacy and safety of patients affected with Primary Open Angle Glaucoma (POAG) and Vitreoretinal Disease, who have undergone Pars Plana Vitrectomy (PPV) and ab-interno XEN gel 45 (Abbvie) implantations. Methods: This is a retrospective, observational, case series on five patients who underwent combined Pars Plana Vitrectomy and XEN gel Stent 45 implantation at "Careggi Hospital" Eye Clinic of Florence. Best-corrected visual acuity (BCVA) evaluation, intraocular pressure (IOP) measurements with Goldmann applanation tonometer (GAT), and several glaucoma medications were evaluated at the baseline and at one, three, six, and twelve months after surgery. Complications were recorded up to 1 year after surgery. Results: 5 eyes in five patients were enrolled. IOP dropped from an average of 21,2 ± 3,3 mmHg preoperatively to 14,6 ± 1,1 mmHg at the end of the follow-up period (month 12), with a mean percentage reduction of 58%. One patient needed a needling procedure (20%). None needed reintervention. We did not register any case of hypotony (IOP < 6,5 mmHg), hypotony maculopathy and choroidal detachment. The postoperative number of anti-glaucomatous molecules was on average 0,2 ± 0,4. Conclusion: Our results suggested that combined Pars Plana Vitrectomy and XEN gel stent 45 implantation is safe and effective for patients affected by visually significant vitreoretinal diseases and POAG.
