ABSTRACT

CASE REPORT: A 47 year-old female who presented with a bilateral idiopathic multiple pigment epithelial detachment (PED) in a routine visit. This pathology is shown as a rare clinical manifestation, where the outcome is resolution of localized atrophy of the pigment epithelium, with a good functional prognosis. DISCUSSION: PED is a common clinical manifestation in several chorioretinal diseases, particularly in macular degeneration associated with age. Idiopathic PED can be considered as a kind of central type II serous chorioretinopathy. Fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) are complementary tests to study the number, extension, and nature of these PED.

ABSTRACT

OBJECTIVE: to determine central corneal thickness in normal subjects, glaucomatous patients and ocular hypertension patients, to evaluate if the central corneal thickness is related to the presence of glaucoma or ocular hypertension. Furthermore, we aim to verify the relationship between central corneal thickness and severity of glaucomatous visual field loss. METHODS: comparative study including 150 eyes of 150 subjects, separated into three groups: normal (47 eyes), ocular hypertension (35) and glaucomatous (68). This last group was subdividided in three subgroups depending on the Hodapp-Parrish-Anderson criteria for scoring Humphrey visual field defects (initial, moderate and advanced). We evaluated the visual field, the central corneal thickness measured by pachymetry and the intraocular pressure measured by Goldmann tonometry. Results were analysed using the Student's t-test for normally distributed independent samples. RESULTS: the central corneal thickness was 526+/-25 microns (mean +/-standard deviation (SD)) in glaucomatous patients, 560+/-27 microns in ocular hypertension patients, and 556+/-27 microns in the normal group. Statistical significance could be found between the glaucomatous group of patients and the other groups (p< 0.01), but not between the ocular hypertension group and normal subjects (p= 0.4). The comparison between central corneal thickness of the subgroup with advanced damage of the visual field and the two other subgroups was also statistically significant (p< 0.01), but not between the subgroups of initial damage and moderate damage (p= 0.7). CONCLUSIONS: the central corneal thickness in glaucomatous patients is lower than in normal subjects and in ocular hypertension patients. Patients classified as having advanced damage in their visual field have significantly lower central corneal thickness measurements than patients classified as having initial or moderate damage.

ABSTRACT

Objetivo: Determinar el grosor corneal central(GCC) en sujetos normales, pacientes glaucomatosose hipertensos oculares, valorando si el GCC estáasociado con la presencia de glaucoma o de hipertensiónocular. Por otra parte, comprobar la correlaciónentre el GCC y el estadio de afectación delcampo visual (CV).Método: Se realizó un estudio de casos y controles,con 150 ojos de 150 pacientes, divididos en tresgrupos: normales (47 ojos), hipertensos oculares(35) y glaucomatosos (68). A su vez, se establecierontres subgrupos dentro de los sujetos glaucomatosos,dependiendo de la afectación del CV según laclasificación de Hodapp de defectos del campovisual (inicial, moderada y avanzada). Se valoró lacampimetría, la medida del GCC mediante paquimetríaultrasónica y de la PIO con tonómetro deaplanación de Goldmman (TAG). Se aplicó el testde hipótesis t-Student para muestras independientesque siguen una distribución normal.Resultados: La media del GCC en los pacientesglaucomatosos era 526 micras Desviación Estándar (DE) 25, 560 DE 27 en hipertensos oculares y 556DE 27 en los sujetos normales, con diferencias significativasentre el grupo de pacientes glaucomatososy los otros dos (p< 0,01), pero no entre el grupode hipertensos oculares y el de sujetos normales(p= 0,45). En los sujetos glaucomatosos, se encontrarondiferencias con significación estadística entreel GCC del subgrupo con afectación avanzada delCV y los de afectación inicial y moderada(p< 0,01), pero no entre estos dos últimos (p= 0,7).Conclusiones: El GCC en pacientes glaucomatososes menor que en los sujetos controles e hipertensosoculares. Los pacientes glaucomatosos con pérdidade CV avanzada cursan con córneas más delgadasque aquéllos con alteración campimétrica inicial o moderada(AU)
