BACKGROUND AND OBJECTIVE: Posterior vitreous detachment (PVD) is a separation of the posterior hyaloid from the retina that manifests as photopsias and floaters. Optical coherence tomography (OCT) has demonstrated posterior vitreous opacities (PVOs) that may correlate with Shaffer's sign, which may correlate with retinal breaks. PATIENTS AND METHODS: Patients with symptomatic PVDs were retrospectively reviewed at a single institution by a single provider. Masked qualitative review of SD-OCTs by a single reviewer determined presence of PVOs. RESULTS: Among 78 patients, PVOs were found in 32 of the patients (41%), and 19 (59%) had retinal breaks. In those without PVOs, six (13%) had a break. Sensitivity and specificity were 76.0% and 75.5%, respectively. Removing patients with vitreous hemorrhages, sensitivity, and specificity of PVOs was 82.4% and 86.4%, respectively. CONCLUSION: In symptomatic PVDs, PVOs on OCT correlated with the presence of a retinal break, especially in the absence of a vitreous hemorrhage.

Introduction In 2018, a unique maculopathy associated with chronic pentosan polysulfate sodium (PPS) use for the treatment of interstitial cystitis (IC) was described, where the authors detailed macular retinal pigment epithelial abnormalities in six patients. In this paper, a retrospective study of a larger patient pool at one large tertiary retina practice was undertaken to evaluate patients taking PPS and their macular findings. Materials and methods A retrospective chart review was performed on all patients presenting to a single large retina practice between 2011 and 2019. Patient’s macular diagnosis, findings, optical coherence tomography scans, and macular auto-fluorescent scans were assessed. This project was Institutional Review Board (IRB) approved by the St Luke’s Hospital IRB board (St Louis, MO, USA). Results Fifty-five patients were identified as taking PPS for IC. Fifty-three patients were found to have a diagnosis consistent with changes attributable to known macular diseases to include macular degeneration and pattern dystrophies. Two (4%) of fifty-five patients had macular findings suggestive of PPS toxicity. The first was a 58-year-old female with subtle retinal pigment epithelium (RPE) deposits on optical coherence tomography that exhibited hyper-autofluorescence. The second was a 72-year-old female with 14 years of PPS use who exhibited RPE excrescences and parafoveal areas of atrophy. Conclusions Pentosan polysulfate sodium may be the cause of macular findings in a small percentage of patients referred to a tertiary retina practice. Although causation of macular changes with PPS use has yet to be elucidated, clinicians should be aware of this possibility when assessing patients with atypical macular findings. Future longitudinal studies are necessary to evaluate a definitive relationship. This paper should remind all clinicians of the importance of a throughout review of the patient’s medication list as novel toxicities may become apparent years after initial FDA trials. The strength of this study is the larger patient population compared to earlier studies, and the main weaknesses include the retrospective nature of the study, lack of family and genetic testing, and lack of multimodal imaging for all patients.
Purpose: This work reports long-term outcomes in macular telangiectasia type 2 (MacTel) with subretinal neovascularization (SRNV). Methods: A retrospective, single-center review of medical records was performed on all patients with a diagnosis of MacTel presenting between May 2004 and October 2019. Medical and ocular history, best-corrected visual acuity (BCVA) at baseline and final visit, optical coherence tomography data, and treatment history of SRNV secondary to MacTel were recorded. Results: A total of 471 eyes were diagnosed with MacTel. SRNV was present in 44 eyes (9.3%), of which 38 eyes met inclusion criteria for SRNV. Average follow-up duration in the SRNV group was 78.4 months. All SRNV patients underwent antivascular endothelial growth factor (anti-VEGF) therapy. There was no significant change from mean baseline (0.59 ± 0.45) to final (0.70 ± 0.49) BCVA in the SRNV group as a whole ( P = .13). Subgroup analysis revealed 17 of 38 eyes had SRNV at diagnosis and received immediate anti-VEGF treatment. In this subgroup mean pretreatment BCVA was 0.89 ± 0.43 and the mean final BCVA was 0.87 ± 0.61 ( P = .84). The remainder (21 of 38 eyes) developed SRNV during follow-up. In this subgroup, final BCVA after initiation of treatment was 0.56 ± 0.32, an improvement in BCVA from SRNV onset ( P = .04) and a decrease from pre-SRNV onset baseline BCVA ( P = .008). Conclusions: Visual acuity is maintained, not improved, in long-term follow-up of MacTel with SRNV treated with anti-VEGF. Patients presenting with SRNV have a worse prognosis than those who develop SRNV during follow-up.
