Summary
Validated questionnaires can help diagnose ocular neuropathic pain. Disease-specific tools are limited, while general ophthalmic questionnaires lack reliability for evaluating ocular pain.
Area of Science:
- Ophthalmology
- Pain Management
- Psychometrics
Background:
- Ocular neuropathic pain diagnosis requires validated assessment tools.
- Current questionnaires vary in quality and applicability.
- Identifying reliable instruments is crucial for accurate evaluation.
Purpose of the Study:
- To identify and assess the quality of validated questionnaires for ocular neuropathic pain.
- To evaluate the psychometric properties and reliability of existing instruments.
- To review associated etiological factors and clinical associations.
Main Methods:
- Comprehensive literature search across multiple databases (MEDLINE, PubMed, EMBASE, PsycINFO, Cochrane Library).
- Inclusion of articles evaluating questionnaires for ocular neuropathic pain and its causes.
- Extraction and quality assessment of data on psychometric properties, validity, and reliability.
Main Results:
- 61 publications covering 28 questionnaires met inclusion criteria.
- The Contact Lens Discomfort Index (CLDI) showed the highest psychometric properties.
- Disease-specific questionnaires were appropriate for their populations, but non-disease-specific ones lacked reliability.
- The English Ocular Comfort Index (OCI) provided extensive psychometric data.
Conclusions:
- Ocular pain questionnaires show potential for diagnosing neuropathic pain.
- Disease-specific questionnaires are limited to their target populations.
- Non-disease-specific ophthalmic questionnaires demonstrated poor reliability and validity.
- Further research is needed to identify the optimal questionnaire for ocular neuropathic pain.

01:25Glaucoma: Overview
614
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
474
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
555
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
857
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
