- Asymptomatic chronic red eye: a surgical technique case reportPublication . Matos, Diogo Bernardo; Guerra, Paulo; José, Patrícia; Ferreira, Rui; Quintas, Ana; Marques-Neves, CarlosIntroduction and importance: Ocular Surface Squamous-cell Neoplasia (OSSN) is an infrequent diagnosis whose clinical suspicion assumes great importance and should not be overlooked. The following case-report aims to describe the diagnosis and treatment of a patient with OSSN whose complaints were mild in comparison to the severity of the disease. The chosen surgical technique was paramount for a disease-free outcome while minimizing the scarring effects of surgical removal. Case presentation: Patient presented mild discomfort right eye and painless persistent hyperaemia. Slit-lamp observation showed a clear diagnosis and lesion's extent evaluated through multimodal imaging. After surgical excision the patient underwent topical ocular treatment with mitomycin-C for a higher margin of safety even before the pathology results were available. Discussion: Ancillary exam technology improvement has allowed a higher margin of safety while determining the extent of OSSN lesions. In the absence of clear diagnostic criteria and guidelines, clinical reasoning and OSSN awareness are critical for timely diagnosis and treatment, as several treatment options are available, allowing an increasing number of patients to be treated non-invasively. In this case-report, we highlight the importance of early-recognition and the reasoning for choosing a combined treatment option with a higher margin of safety. Conclusion: Early recognition and prompt treatment of OSSN lesions is of paramount importance to avoid ocular invasiveness and potentially preclude both ocular and systemic complication. The choice of a combined surgical and medical approach may provide a higher margin of safety for suitable cases. This patient is currently disease-free at 6-month follow-up.
- Glaucoma triage system: results of implementing a virtual clinicPublication . Matos, Diogo Bernardo; Correia Barão, Rafael; José, Patrícia; Lima-Cabrita, Afonso; Barata, Andre; Pinto, LuisPurpose: This study describes the virtual clinic triage system implementation process at Hospital Santa Maria-Centro Hospitalar Universitário Lisboa Norte (HSM-CHULN) and analyzes its results regarding healthcare outcomes for the patients and the system. Methods: A retrospective analysis was performed, comparing two cohorts (pre-virtual cohort; virtual triage cohort). Outcomes related to waiting time, number of hospital visits, decisions at first contact, and ancillary exam-based decisions were reported. Results: Two hundred and ninety-two charts were reviewed (pre-virtual cohort: 132; virtual cohort: 160). Mean waiting time between referral and the first medical contact with the glaucoma department decreased on average by 71.3 days (human contact: 286.6 days; virtual triage contact: 215.3 days). Triage system significantly decreased waiting time for glaucoma patients, with an average decrease of 326.8 days between referral and treatment decision. Triage staging allowed to label 107 (66.9; 95% confidence intervals (CI): 59.6%, 74.2%) as non-urgent; 30 (18.8%; 95% CI: 12.7%, 24.9%) as urgent, and 23 (14.3%; 95% CI: 8.9%, 19.7%) as immediate contact, with the scheduling of future appointments reflecting National Institute for Health and Care Excellence (NICE) guidelines in every patient. Moreover, the number of visits to perform the same exams and obtain the same clinical decisions was reduced by 63.6%. Conclusion: Our virtual screening strategy significantly decreased waiting time, number of hospital visits, and increased chances of data-assisted clinical decision. While results can be further improved, this system can add value in an overburdened healthcare system, where triage systems with remote decision-making may be valuable tools in optimizing glaucoma care, even without allocation of extra resources.
- Design and development of a web-based prospective nationwide registry for ocular inflammatory diseases: UVEITE.PT - The Portuguese Ocular Inflammation RegistryPublication . Leal, Ines; Nogueira, Vanda; Matos, Diogo Bernardo; Araújo, Joana; Berens, Olga; Ribeiro, Margarida; Furtado, Maria João; Liverani, Marco; Silva, Marta Inês; Guedes, Marta; Cordeiro, Miguel; Ribeiro, Miguel; José, Patrícia; Correia Barão, Rafael; Nunes Ferreira, Rui; Fonseca, Sofia; Sousa Mano, Sofia; Pina, Susana; Santos, Maria; Fonseca, João Eurico; Fonseca, Cristina; Figueira, LuísUveitis is a heterogeneous collection of infrequent diseases, which poses significant challenges to cost-effective research in the field. Medical registries are being increasingly recognized as crucial tools to provide high-quality data, thus enabling prospective clinical research. This paper describes the design and technical structure development of an innovative countrywide electronic medical record for uveitis, Uveite.pt, and gives an overview of the cohort registered since its foundation, March 2020.Uveite.pt is an electronic medical record platform developed by the Portuguese Ocular Inflammation Group (POIG), a scientific committee of the Portuguese Ophthalmology Society. This is a nationwide customized web-based platform for uveitis patients useful for both clinical practice and real-world-based research, working as a central repository and reporting tool for uveitis. This paper describes the technical principles, the design and the development of a web-based interoperable registry for uveitis in Portugal and provides an overview of more than 400 patients registered in the first 18 months since inception.In infrequent diseases, the existence of registries enables to gather evidence and increase research possibilities to clinicians. The adoption of this platform enables standardization and improvement of clinical practice in uveitis. It is useful to apprehend the repercussion of medical and surgical treatments in uveitis and scleritis, supporting clinicians in the strict monitoring of drug adverse reactions and surgical outcomes.
- Bleb morphology of glaucoma drainage devices on magnetic resonance imagingPublication . Correia Barão, Rafael; Berhanu, David; Matos, Diogo Bernardo; Barata, Andre; Sousa, Rita; Pinto, LuisPurpose: To evaluate bleb morphology features of different glaucoma drainage devices (GDD) using magnetic resonance imaging (MRI). Materials and methods: Prospective cohort study of GDD and bleb morphology in consecutive glaucoma patients implanted with Ahmed Glaucoma Valve (AGV), Paul Glaucoma Implant (PGI), Baerveldt Glaucoma Implant (BGI) and Ahmed ClearPath (ACP) devices. Thirty-six eyes from 30 consecutive patients underwent standardized GDD implantation followed by MRI at least 1 month after surgery. Main outcomes included bleb volume and endplate position relative to the optic nerve. Secondary outcomes included intraocular pressure (IOP), medication and surgical complications during a 12-month follow-up. Results: Seven eyes were implanted with the AGV (19%), 5 with BGI (14%), 16 with PGI (44%) and 8 with ACP (22%). MRI scans were obtained 85 ± 66 days after surgery. Mean total bleb volume was 563 ± 390 mm3 . This bleb volume was inversely correlated with early post-operative IOP (day 7; rs = -0.3326, p = 0.0475) but positively correlated with IOP at 12 months (rs = 0.3592, p = 0.0341). No significant difference in total bleb volume was found between GDD types (p = 0.1223). A double-layered bleb was observed in 34 eyes (94%). The inferior bleb volume was significantly larger in PGI devices versus other GDD types (380 ± 205 vs. 193 ± 161 mm3 ; p = 0.0043). Distance from the endplate to the optic nerve was 9.5 ± 4.0 mm, similar across GDDs (p = 0.2519). Conclusions: Double-layered blebs are a common finding with GDDs. Bleb volume showed different correlations with IOP at distinct timepoints and the PGI device formed larger blebs. A standardized GDD implantation technique ensures a safe distance from the GDD endplate to the optic nerve.
