Summary
Scleral contact lenses (ScCLs) offer a comfortable and effective long-term solution for managing complex ptosis, improving eyelid elevation. While patients report satisfaction, objective cosmetic grading shows varied results, with most finding it acceptable.
Area of Science:
- Ophthalmology
- Optometry
- Biomedical Engineering
Background:
- Complex ptosis presents challenges for surgical correction.
- Scleral contact lenses (ScCLs) are explored as a non-surgical management option.
Purpose of the Study:
- To evaluate the efficacy of ScCLs for managing complex ptosis.
- To assess ScCLs as an alternative or adjunct to surgical correction.
Main Methods:
- Retrospective case-note review of 10 patients with 14 treated eyes.
- Objective measurement of palpebral aperture (PA) and upper margin-reflex distance (UMRD) using digital photography and analytic software.
- Subjective and masked observer grading of cosmetic acceptability.
Main Results:
- ScCL wear significantly increased mean PA (4.9mm to 9.5mm) and UMRD (0.39mm to 3.1mm) (p < 0.005).
- Long-term wearers reported comfort and cosmetic acceptability.
- Objective cosmesis grading: 22% good, 64% moderate, 14% poor.
Conclusions:
- ScCLs provide a well-tolerated, practical long-term solution for complex ptosis.
- Patient satisfaction with cosmesis is high, despite subjective limitations.
- ScCLs offer a safe method for upper eyelid elevation in select cases.

01:28Angle Closure Glaucoma: Treatment
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...
01:25Glaucoma: Overview
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
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.
