Summary
Recurrent pterygium is linked to more severe dry eye disease (DED). This may be due to ongoing ocular inflammation after surgery, impacting tear production and eye comfort.
Area of Science:
- Ophthalmology
- Ocular Surface Disease
Background:
- Pterygium, a common eye condition, can recur after surgical excision.
- Recurrence may be associated with ocular surface changes and inflammation.
Purpose of the Study:
- To investigate the prevalence and severity of dry eye disease (DED) in patients with recurrent pterygium.
- To assess the relationship between pterygium recurrence and DED.
Main Methods:
- A study involving 55 patients who underwent pterygium excision.
- Patients were categorized into groups based on pterygium recurrence after first or second excision.
- Dry eye symptoms and tear production (Schirmer test) were evaluated for all participants.
Main Results:
- A high prevalence of DED was found in patients with primary and recurrent pterygium (63.6% symptoms, 78.1% abnormal Schirmer test).
- Significantly lower Schirmer test values were observed in patients with pterygium recurrence compared to those without (5.6 mm vs. 11.4 mm, p=0.025).
- Improved, though not statistically significant, Schirmer test values were noted in patients successfully treated after a second excision.
Conclusions:
- Pterygium recurrence is associated with increased severity of dry eye disease.
- Persistent ocular surface inflammation post-surgery may contribute to DED in recurrent pterygium cases.

01:30Dry Friction

Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.

01:21Drying Shrinkage
376
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

01:21Characteristics of Dry Friction
985
Dry friction occurs when two solid surfaces slide against each other without any lubrication or fluid present. It causes resistance when pushing objects along a surface, like a gardener pushing a wheelbarrow. The force applied to move the cart causes dry friction between the wheel and the ground.
Before the wheelbarrow starts moving, the static frictional force acts tangentially to the contact surface, opposing the force that is about to induce the motion. This frictional force prevents the...

01:20Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

00:52Washing, Drying, and Ignition of Precipitates
6.8K
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...

01:17Accessory Structures of the Eye
3.6K
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...
