Quality of Life Measures in Patients With Retinal Degeneration

2016-06-27 20:53:21 | BioPortfolio


Inherited retinal degeneration (IRD) is a major cause of blindness and partial loss of vision cases in the UK and starts at an early age. The purpose of this observational study is to use the results of two questionnaires and a computerised test testing contrast sensitivity, to assess the impact of IRD on quality of life. This study will involve collecting data from patients with IRD, but also collecting data from normal controls.


IRD presents a significant burden on the NHS as well as on the individual and families. IRDs are particularly difficult in a family situation due to guilt and other complex emotions related to inheritance patterns. Poorer mental health has been reported in patients with retinitis pigmentosa, manifesting in a range of ways including stress, depression and anxiety, particularly as the disease progresses. This is most probably caused by the uncertainty of the disease process and the progressive nature of the degeneration.

Recent work has reported that quality of life significantly deteriorates with a drop in visual field diameter of 20 degrees or a drop in visual acuity lower then LogMAR 0.3 (equivalent to 6/12). Contrast sensitivity is often used in conjunction with VA to assess visual capabilities. It is a measure of the ability to see reduced contrast and has a major impact on utility of vision. Relating contrast sensitivity function to quality of life will provide valuable information about whether this aspect of vision is a critical measure for patient health. This is especially important as novel treatments are being developed for the treatment of IRDs.

Medical and Biotech [MESH] Definitions

A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)

Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.

Perforations through the whole thickness of the retina including the macula as the result of inflammation, trauma, degeneration, etc. The concept includes retinal breaks, tears, dialyses, and holes.

A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.

Function of the human eye that is used in dim illumination (scotopic intensities) or at nighttime. Scotopic vision is performed by RETINAL ROD PHOTORECEPTORS with high sensitivity to light and peak absorption wavelength at 507 nm near the blue end of the spectrum.
