“…However, all cataract patients were drawn from the cataract-surgery waiting list, and the key indicator for cataract surgery is, precisely, visual disability attributed to cataract. [32][33][34] Therefore, this population, by definition, does have visual disability, a fact that was also previously demonstrated. 35 A lack of unidimensionality was a second limitation of the AVL scale in the present study.…”

PURPOSE:The Adaptation to Age-related Vision Loss (AVL) scale was developed to measure the adjustment of older adults who are adapting to late-life vision loss. The purpose of this study was to assess whether the AVL scale satisfies the Rasch model in a cataract population. METHODS:The 24-item AVL scale (18 negatively and 6 positively coded) was mailed to 436 cataract patients for self-administration whilst they were on the waiting list for cataract surgery at the Flinders Eye Centre, Adelaide, South Australia. Rasch analysis was performed to determine whether the items were measuring a single construct (unidimensionality) as examined with fit statistics and principal components analysis (PCA) of the residuals. The ability of the scale to distinguish between the levels of adaptation of the participants (person separation) was investigated, with a value ≥ 2.0 established as the minimum acceptable. RESULTS: The AVL scale was unable to differentiate sufficiently between participants' levels of adaptation, indicating poor person separation. One item did not fit the construct, causing misfit. Furthermore, the five positively worded items did not appear either to measure the same construct as other items, resulting in lack of unidimensionality evidenced by PCA. Following the deletion of these items, the AVL scale was one-dimensional but a single item continued to misfit, so it had to be deleted, resulting in an 18-item AVL scale. Even so, the discriminating abilities of the scale continued to be poor. CONCLUSIONS: The AVL scale is not an appropriate measure of adaptation to vision loss in a cataract population. KEY WORDS: Rasch analysis; adaptation to Age-related Vision Loss Scale; cataract; Australia. RESUMEN OBJETIVO: La Escala de adaptación a la pérdida visual relacionada con la edad (o sus siglas en inglés, AVL) se desarrolló para medir el ajuste de los adultos de edad avanzada ante la pérdida visual que suele aparecer en esta fase de la vida. El propósito de este estudio era evaluar si la escala AVL también se ajusta al modelo de Rasch en una población de personas con cataratas. MÉTODOS: Se envió por correo postal el cuestionario correspondiente a la escala AVL de 24 elementos (18 codificados negativamente y 6 positivamente) a 436 pacientes del Flinders Eye Centre, Adelaida, South Australia (Australia) que se encontraban en la lista de espera para cirugía de cataratas. Los pacientes debían completar el cuestionario y devolverlo por correo. Se realizó un análisis de Rasch de los resultados para determinar si todos los elementos de la escala están midiendo un único parámetro (unidimensionalidad). Esto se llevó acabo utilizando estadísticos de ajuste así como análisis de componentes principales (o sus siglas ACP) de los residuos. Se evaluó la capacidad de la escala para discriminar entre los distintos niveles de adaptación de los participantes (denominada separación o fiabilidad), estableciendo un valor umbral de 2,0 como el valor mínimo aceptable. RESULTADOS: La escala AVL no fue capaz de diferenciar de fo...

PURPOSE. We determined if the Impact of Vision Impairment (IVI) is a valid questionnaire to measure the vision-related quality of life (VRQoL) in keratoconus patients, and investigated if the VRQoL varied with disease severity in this sample. METHODS.We recruited 160 consecutive bilateral keratoconus patients (mean age 23.3 years, 63% male) from an Indian tertiary eye care center. Participants underwent a clinical examination and completed the IVI. Participants were divided into three groups based on the average of the steep keratometry (K) readings: mild (average Sim K < 45 diopters [D]), moderate (average Sim K 45-52 D), and severe (average Sim K > 52 D). Rasch analysis was used to validate the IVI and the VRQoL scores thus obtained were compared across the disease groups.RESULTS. The majority (63%) of patients had severe, while the remainder (37%) had moderate keratoconus. Rasch analysis demonstrated the validity of the IVI to assess VRQoL through two subscales: vision-specific functioning (VF) and emotional well-being (EWB). There was no significant difference in VF (mean change À0.16, P ¼ 0.55) and EWB scores (mean change À0.32, P ¼ 0.23) between moderate and severe keratoconus groups.CONCLUSIONS. The revised IVI subscales have interval-level measurement properties, which support their suitability to measure VRQoL in this keratoconus sample. Patients with moderate or severe keratoconus had similar, but higher VRQoL scores as assessed by the revised IVI subscales, indicating lack of impact of the disease on their VRQoL. However, this does not exclude the possibility of finding an impact in other populations.

“…Zaključak je da je operacija katarakte opravdana kod pacijenata sa lakom formom senilne degeneracije makule i da odlaganje može negativno uticati na ukupan kvalitet života pacijenata [6]. U drugoj sprovedenoj studiji pacijenti sa senilnom degeneracijom makule su posle operacije katarakte imali niži stepen poboljšanja vidne oštrine ili istu vidnu oštrinu u odnosu na pacijente sa primarnim glaukomom otvorenog ugla, ali ipak je evidentno da je 62,5% pacijenata sa senilnom degeneracijom makule imalo poboljšanje vidne oštrine [8].…”

Vukša Dubravka1, Stamenković Divna1, Đokić Olivera2, Mirković Jana2 1KBC Priština, Gračanica, Republika Srbija 2Medicinski fakultet Priština, Kosovska Mitrovica, Republika Srbija Uvod: Katarakta vezana za starenje tj.senilna katarakta je jedan od vodećih uzroka preventabilnog slepila u svetu. Cilj rada: Utvrditi da li udružena oftalmološka stanja (glaukom, senilna degeneracija makule, dijabetička retinopatija i sl.) utiču na vidnu funkcionalnost i kvalitet života pacijenata sa kataraktom i pseudofakijom, i ukoliko je to moguće, utvrditi koje udruženo stanje ima značajniji uticaj. Metode rada: Istraživanjem su obuhvaćena 202 pacijenta u zavisnosti od statusa katarakte na drugom, pratećem oku, pacijenti su podeljeni u dve grupe posmatranja: katarakta pseudofakija. Rezultati: Pacijenti sa miopijom i kapsularnim glaukomom su nakon operacije imali značajno poboljšanje prosečne vidne oštrine (0,87 vs. 0,65) u odnosu na preoperativni nalaz (0,38 vs. 0,24) (p<0,01). Takođe, i pacijenti koji su imali senilnu degeneraciju makule i neproliferativnu dijabetičku retinopatiju sa prosečnom preoperativnom vidnom oštrinom (0,05 vs. 0,05) nakon hirurške intervencije imaju značajno poboljšanje prosečne vidne oštrine (0,2 vs 0,2) (p<0,01). Značajno poboljšanje prosečne postoperativne vidne oštrine (0,28) u odnosu na preoperativni nalaz (0,05) imali su pacijenti sa primarnim glaukomom otvorenog ugla (p<0,01), dok su pacijenti sa primarnim glaukomom zatvorenog ugla kao udruženim nalazom imali poboljšanje prosečne postoperativne vidne oštrine (0,1) u odnosu na preoperativnu (0,05) (p<0,1). Zaključak: Značajno poboljšanje postoperativne prosečne vidne oštrine u odnosu na preoperativne vrednosti dovodi do smanjenja poteškoća u vidno zavisnim aktivnostima, odnosno do poboljšanja kvaliteta života.Ključne reči: hirurgija katarakte, udružen nalaz,vidna oštrina UVODKatarakta vezana za starenje tj.senilna katarakta je jedan od vodećih uzroka preventabilnog slepila u svetu. Senilna katarakta je i najčešća indikacija za elektivnu hirurgiju.Prema podacima Svetske zdravstvene organizacije (SZO) 20 miliona ljudi u svetu je slepo zbog katarakte. Najveća učestalost slepila je u zemljama u razvoju (u Bangladešu je slepo 1,25 miliona ljudi a u Indiji 8 miliona). I u razvijenim zemljama katarakta je najčešći uzrok slepila i slabovidosti, recimo u SAD je vodeći uzrok slepila samo u starijoj populaciji Afro-amerikanaca, sa zastupčjenošću od 30%. Svetska zdravstvena organizacija (SZO) je predložila plan prevencije slepila a jedan od primarnih ciljeva podrazumeva i izvođenje dovoljno velikog broja operacija katarakte. [1,2] Smanjenje ili gubitak vidne funkcije je opterećenje ne samo za pojedince već i za društvo u celini sa socioekonomskog aspekta. Postojeće procene pokazuju da Indija ima oko 2 milijarde dolara godišnji gubitak u ekonomiji zbog katarakte, a sa druge strane da SAD izdvaja godišnje oko 3,4 milijarde dolara samo za operacije katarakte. [3,4] Svakodnevni klinički kriterijum za procenu vizuelne signifikantnosti katarakte je pad centralne vidne ...
