Item Corneal aberrations in primary congenital glaucoma and its visual correlation(International Ophthalmology, 2024) Ly-Yang, Fernando; Morales Fernández, Laura; García Bella, Javier; Garcia Caride, Sara; Santos Bueso, Enrique Miguel; Saenz Frances, Federico; Fernández-Vigo López, José; García Feijoo, Julián; Martínez De La Casa Fernández-Borrella, José MaríaPrimary congenital glaucoma (PCG) can cause permanent vision loss, and its prognosis is related to early detection and treatment. The main pathological defect consists of resistance to aqueous outflow through the trabecular meshwork due to abnormal development of tissue derived from the neural crest in the anterior chamber angle. Even after successful intraocular pressure (IOP) management in PCG poor visual outcomes still present a lifelong challenge. Vision loss in PCG is multifactorial, resulting from optic nerve damage, corneal scarring, and myopic astigmatism associated with anisometropic amblyopia. Although it is already known that children with PCG present with an altered corneal configuration, the knowledge of irregular astigmatism due to high-order aberrations (HOA) and due to the unequal expansion of the anterior segment, and its impact on visual outcomes, is not yet fully understood, to the best of our knowledge. Quality vision is influenced by the presence of aberrations in the eye's optical system, which can degrade the quality of the image projected onto the retina. Low-order aberrations (LOA), including myopia, hyperopia, and regular astigmatism, can be corrected by spectacles, while HOA cannot be corrected by ordinary means. Coma and spherical aberrations are the most visually significant HOAs, while trefoil and other HOAs have a lower impact on visual quality. The purpose of this article is to establish a quantitative correlation between HOA and visual acuity (VA) to measure the magnitude of the impact of the altered cornea on visual outcomes in PCG.Item Corneal densitometry and biomechanical properties in patients with primary congenital glaucoma(Canadian Journal of Ophthalmology, 2021) Morales Fernández, Laura; Benito Pascual, Blanca; Pérez García, Pilar; Perucho González, Lucía; Sáenz Francés, Federico; Santos Bueso, Enrique Miguel; García Bella, Javier; Sánchez Jean, Rubén; García Feijoo, Julián; Martínez De La Casa Fernández-Borrella, José MaríaObjective: To describe corneal densitometry, topographic measurements, and biomechanical properties in patients with primary congenital glaucoma (PCG) and healthy patients. To examine correlations between variables and determine their glaucoma diagnostic capacity. Methods: This was a cross-sectional, case-control study conducted in 50 eyes of 50 patients with PCG (G1) and 40 eyes of 40 healthy patients (G2). The variables determined in each participant were: intraocular pressure, best corrected visual acuity (BCVA), corneal densitometry, topographic data using the Pentacam HR-Scheimpflug imaging system (Oculus Optikgerate GmbH, Wetzlar, Germany), and corneal hysteresis (CH) and corneal resistance factor (CRF) using the Ocular Response Analyzer (Reichert Ophthalmic Instruments, Depew, NY). Results: Overall densitometry was significatively higher in the PCG group (G1: 17.94 ± 4.99 vs G2: 13.25 ± 1.96, p < 0.001). CH (G1: 8.02 ± 11.35 vs G2: 11.35 ± 1.42, p < 0.001) and CRF (G1: 9.48 ± 2.83 vs G2: 10.77 ± 1.34, p < 0.001) were lower in the glaucoma group. Mean posterior, central, and anterior elevation and mean keratometry were higher in G1 (p < 0.05). In the PCG group, overall densitometry showed significant correlation with CH (r = –0.321, p = 0.028) and with BCVA (r = −0.498, p = 0.002). AUCs (areas under the curve) for CH and overall densitometry were high (0.839 and 0.899 respectively) and the best overall densitometry; CH and CRF cutoffs were 14.0, 9.3 and 9.2 respectively. Conclusion: Densitometry is increased, and biomechanical corneal properties are decreased in patients with PCG. Densitometry and visual acuity showed a negative and significant correlation, so this measurement could be used as an indirect parameter of BCVA in the clinical practice.Item Corneal Segmentation Analysis Increases Glaucoma Diagnostic Ability of Optic Nerve Head Examination, Heidelberg Retina Tomograph's Moorfield's Regression Analysis, and Glaucoma Probability Score(Journal of Ophthalmology, 2015) Sáenz Francés, Federico; Jañez Escalada, Luis; Berrozpe Villabona, Clara; Borrego Sanz, Lara; Morales Fernández, Laura; Acebal Montero, Alejandra; Méndez Hernández, Carmen D.; Martínez De La Casa Fernández-Borrella, José María; Santos Bueso, Enrique Miguel; García Sánchez, Julián; García Feijoo, JuliánPurpose. To study whether a corneal thickness segmentation model, consisting in a central circular zone of 1 mm radius centered at the corneal apex (zone I) and five concentric rings of 1 mm width (moving outwards: zones II to VI), could boost the diagnostic accuracy of Heidelberg Retina Tomograph's (HRT's) MRA and GPS. Material and Methods. Cross-sectional study. 121 healthy volunteers and 125 patients with primary open-angle glaucoma. Six binary multivariate logistic regression models were constructed (MOD-A1, MOD-A2, MOD-B1, MOD-B2, MOD-C1, and MOD-C2). The dependent variable was the presence of glaucoma. In MOD-A1, the predictor was the result (presence of glaucoma) of the analysis of the stereophotography of the optic nerve head (ONH). In MOD-B1 and MOD-C1, the predictor was the result of the MRA and GPS, respectively. In MOD-B2 and MOD-C2, the predictors were the same along with corneal variables: central, overall, and zones I to VI thicknesses. This scheme was reproduced for model MOD-A2 (stereophotography along with corneal variables). Models were compared using the area under the receiver operator characteristic curve (AUC). Results. MOD-A1-AUC: 0.771; MOD-A2-AUC: 0.88; MOD-B1-AUC: 0.736; MOD-B2-AUC: 0.845; MOD-C1-AUC: 0.712; MOD-C2-AUC: 0.838. Conclusion. Corneal thickness variables enhance ONH assessment and HRT's MRA and GPS diagnostic capacity.Item Correlations between corneal and optic nerve head variables in healthy subjects and patients with primary open angle glaucoma(International journal of ophthalmology, 2015) Sáenz Francés, Federico; Jañez Escalada, Luis; Borrego Sanz, Lara; Berrozpe Villabona, Clara; Martínez De La Casa Fernández-Borrella, José María; Morales Fernández, Laura; García Sánchez, Julián; Santos Bueso, Enrique Miguel; García Feijoo, JuliánAIM: To correlate corneal variables (determined using the Pentacam) with optic nerve head (ONH) variables determined using the Heidelberg retina tomograph (HRT) in healthy subjects and patients diagnosed with primary open angle glaucoma (POAG). METHODS: Measurements were made in 75 healthy eyes and 73 eyes with POAG and correlations examined through Pearson correlation coefficients between the two sets of variables in the two subject groups. The corneal variables determined were corneal volume (CVol), central corneal thickness (CCT), overall corneal thickness (OvCT), the mean thickness of a circular zone centered at the corneal apex of 1 mm radius (zone I) and the mean thickness of several concentric rings, also centered at the apex until the limbus, each of 1 mm width (zones II to VI respectively). The ONH variables were determined using the HRT. RESULTS: The following pairs of variables were correlated in the control group: CCT-disc area (DAr) (-0.48; P<0.0001), Zone I-DAr (-0.503; P<0.0001) and Zone II-DAr (-0.443; P<0.0001); and in the POAG group: CCT-cup-to-disc area ratio (CDRa) (-0.402; P<0.0001), Zone I-CDRa (-0.418; P<0.0001), Zone II-CDRa (-0.405; P=0.006), Zone I-cup shape measure (CSM) (-0.415; P=0.002), Zone II-CSM (-0.405; P=0.001), Zone IV-height variation contour (HVC) (0.378; P=0.002); Zone V-HVC (0.388, P<0.0001). CONCLUSION: AS-OCT-derived lens thickness measurement is valid and comparable to the results obtained by A-scan US. It can be used as a reliable noncontact method for measuring lens thickness in adults with or without significant cataract.Item Cumplimiento del tratamiento del glaucoma(Archivos de la Sociedad Española de Oftalmología, 2014) Santos Bueso, Enrique Miguel; Sáenz Francés, Federico; García Sáenz, Sofía; Méndez Hernández, Carmen D.; Fernández Vidal, Ana M.; Morales Fernández, Laura; Martín Valdizán, Carmen; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; García Sánchez, JuliánItem Dependence of dynamic contour and Goldmann applanation tonometries on peripheral corneal thickness(International journal of ophthalmology, 2017) Sáenz Francés, Federico; Sanz Pozo, Claudia; Borrego Sanz, Lara; Jañez Escalada, Luis; Morales Fernández, Laura; Martínez De La Casa Fernández-Borrella, José María; García Sánchez, Julián; García Feijoo, Julián; Santos Bueso, Enrique MiguelAIM: To determine the effects of peripheral corneal thickness (PCT) on dynamic contour tonometry(DCT) and Goldmann applanation tonometry (GAT). METHODS: A cross-sectional study. We created a software which calculates the corneal contour (CC) as a function of the radius from the corneal apex to each pixel of the contour. The software generates a central circumference with a radius of 1 mm and the remainder of the cornea is segmented in 5 rings concentric with corneal apex being its diameter not constant around the corneal circumference as a consequence of the irregular CC but keeping constant the diameter of each ring in each direction of the contour. PCT was determined as the mean thickness of the most eccentric ring. Locally weighted scatterplot smoothing (LOWESS) regression was used to determine the pattern of the relationship between PCT and both DCT and GAT respectively. Thereafter, two multivariable linear regression models were constructed. In each of them, the dependant variable was intraocular pressure (IOP) as determined using GAT and DCT respectively. In both of the models the predictive variable was PCT though LOWESS regression pattern was used to model the relationship between the dependant variables and the predictor one. Age and sex were also introduced control variables along with their first-degree interactions with PCT. Main outcome measures include amount of IOP variation explained through regression models (R2) and regression coefficients (B). RESULTS: Subjects included 109 eyes of 109 healthy individuals. LOWESS regression suggested that a 2nd-degree polynomial would be suitable to model the relationship between both DCT and GAT with PCT. Hence PCT was introduced in both models as a linear and quadratic term. Neither age nor sex nor interactions were statistically significant in both models. For GAT model, R2 was 17.14% (F=9.02; P=0.0002), PCT linear term B was -1.163 (95% CI: -1.163, -0.617). PCT quadratic term B was 0.00081 (95% CI: 0.00043, 0.00118). For DCT model R2 was 14.28% (F=9.29; P=0.0002), PCT linear term B was -0.712 (95% CI: -1.052, -0.372), PCT quadratic term was B=0.0005 (95% CI: 0.0003, 0.0007). CONCLUSION: DCT and GAT measurements are conditioned by PCT though this effect, rather than linear, follows a 2nd-degree polynomial pattern.Item Cese paradójico de un caso de síndrome de Charles Bonnet(Archivos de la Sociedad Española de Oftalmología, 2014) Santos Bueso, Enrique Miguel; Serrador García, Mercedes; Sáenz Francés, Federico; Méndez Hernández, Carmen Dora; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; García Sánchez, JuliánCaso clínico: paciente varón de 78 años diagnosticado de síndrome de Charles Bonnet (SCB) por déficit visual secundario a glaucoma terminal. Evolucionó a amaurosis, presentando desaparición brusca de las alucinaciones de forma paralela a la pérdida del resto visual. Discusión: el cese paradójico del SCB se produce cuando el paciente pierde el resto visual, evolucionando a amaurosis. La falta de estimulación en la retina y el córtex correspondiente hacen desaparecer las alucinaciones debido a que las neuronas desaferentadas e hiperexcitadas pierden el estímulo que desencadena el SCB.Item Changes in corneal biomechanical properties after 24 hours of continuous intraocular pressure monitoring using a contact lens sensor(Canadian Journal of Ophthalmology, 2017) Morales Fernández, Laura; García Bella, Javier; Martínez De La Casa Fernández-Borrella, José María; Sánchez Jean, Rubén; Sáenz Francés, Federico; Arriola Villalobos, Pedro; Perucho González, Lucía; Santos Bueso, Enrique Miguel; García Feijoo, JuliánObjective: This study was designed to assess changes in corneal topography and biomechanics after intraocular pressure (IOP) monitoring using the Triggerfish contact lens sensor (CLS). Methods: For this prospective study, 30 eyes of 30 subjects: 14 healthy subjects (G1) and 6 glaucoma patients (G2), were recruited for 24 hours of continuous IOP monitoring using the CLS. The following measurements were taken before CLS fitting and after lens removal: maximum keratometry (Kmax), mean keratometry (MK), and corneal astigmatism (Cyl) measured through Pentacam corneal topography, and the corneal biomechanical variables corneal hysteresis (CH) and corneal resistance factor (CRF) measured with the Ocular Response Analyzer (ORA). Results: Pentacam data revealed significant changes after CLS removal in Kmax (+3.14 ± 2.46 D, p = 0.002), MK (+0.52 ± 0.63 D, p = 0.02), and Cyl (+0.48 ± 0.53 D, p = 0.019) in G1; and Kmax (+1.38 ± 1.43 D, p = 0.002) in G2. The changes observed were more pronounced in G1 than in G2 but differences were not significant. The ORA results indicated higher CH (11.35 ± 2.42 vs 8.17 ± 2.09) and CRF (10.3 ± 2.03 vs 9.1 ± 1.81) before lens fitting in G1 than G2, while no significant changes were produced after CLS removal in either group. Conclusions: The use of CLS for IOP monitoring over 24 hours caused topographic changes in both healthy subjects and glaucoma patients. No changes were produced in corneal biomechanics.Item Charles Bonnet syndrome in a child with congenital glaucoma(Archivos de la Sociedad Española de Oftalmología, 2017) Santos Bueso, Enrique Miguel; Serrador García, Mercedes; Sáenz Francés, Federico; Méndez Hernández, Carmen Dora; Morales Fernández, Laura; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; Porta-Etessam, JesúsCase report: The case is presented of a 12 year-old boy with congenital glaucoma and low visual acuity diagnosed with Charles Bonnet syndrome. This consisted of the acute onset of complex, repetitive, persistent, and with visual hallucinations (people, brooms and coffeemakers) of self-limited evolution without treatment. The patient was diagnosed with congenital glaucoma at 3 years of age, and subjected to a trabeculectomy in right eye, and trabeculectomy and keratoplasty in his left eye. Discussion: Charles Bonnet syndrome symptoms have been described in adults, but their presence in children is poorly reflected in literature, with unknown characteristics and prevalence.Item Hipertensión arterial secundaria a tratamiento con latanoprost(Archivos de la Sociedad Española de Oftalmología, 2015) Santos Bueso, Enrique Miguel; Sáenz Francés, Federico; Palmero Fernández, Laura; García Sáenz, Sofía; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; García Sánchez, JuliánCaso clínico: mujer de 80 años intervenida mediante trabeculectomía por glaucoma primario de ángulo abierto en la que, debido al incremento tensional, se inició tratamiento con latanoprost. La monitorización de la tensión arterial (TA) demostró un incremento estadísticamente significativo de la TA tanto sistólica como diastólica coincidiendo con el uso del hipotensor tópico, que se resolvió al suspender voluntariamente el tratamiento, volviendo a elevarse al reintroducir la prostaglandina. Discusión: los análogos de las prostaglandinas disminuyen la presión intraocular al producir vasodilatación de las arterias ciliares y epiesclerales, aumentando el drenaje del humor acuoso. Los efectos cardiovasculares son poco frecuentes pero se han descrito por el efecto vasoconstrictor que puede desencadenarse como el incremento reversible de la TA de este caso.
