Summary
Contact lens wear significantly increases the risk and severity of conjunctivochalasis, a condition that worsens with age. This study highlights contact lens wear as a key risk factor for developing this ocular condition.
Area of Science:
- Ophthalmology
- Contact Lens Research
- Ocular Surface Disease
Background:
- Conjunctivochalasis is an age-related condition affecting the conjunctiva.
- The impact of contact lens wear on conjunctivochalasis severity is not well-established.
Purpose of the Study:
- To evaluate the association between age and conjunctivochalasis incidence and severity in contact lens wearers.
- To compare conjunctivochalasis severity between contact lens wearers and non-wearers.
Main Methods:
- A prospective study involving 600 contact lens wearers (hard and soft) and 579 non-wearers, aged 10-60.
- Grading of conjunctivochalasis at nasal, middle, and temporal locations.
- Assessment of age, gender, medical/ocular history, and conjunctivochalasis parameters.
Main Results:
- Conjunctivochalasis prevalence and severity increased significantly with age in all groups.
- Contact lens wearers exhibited higher conjunctivochalasis grades than non-wearers (P < .00001).
- Hard contact lens wearers showed greater severity than soft contact lens wearers (P < .00001).
Conclusions:
- Contact lens wear is a significant risk factor for developing conjunctivochalasis.
- Age and duration of contact lens wear exacerbate conjunctivochalasis.
- This study provides the first assessment of conjunctivochalasis severity in a large cohort of contact lens wearers.

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...
01:28Angle 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...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
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.

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
