Hypotony of Eye Due to Other Ocular Disorders

Hypotony of the eye refers to low intraocular pressure (IOP) which can be caused by various ocular disorders. The normal range of IOP is between 10 and 21 mmHg, and hypotony occurs when the IOP falls below 6 mmHg. It can lead to various complications, including vision loss, cataracts, and macular edema. In this article, we will discuss the ocular disorders that can cause hypotony and their management.

1. Uveitis: This is an inflammation of the uvea, which is the middle layer of the eye. Uveitis can cause hypotony by reducing the production of aqueous humor, which is a fluid that maintains the IOP. Treatment of uveitis involves the use of corticosteroids and immunosuppressive agents to reduce inflammation.
2. Globe rupture: This is a serious injury to the eye that can cause hypotony. It occurs when the outer coat of the eye is ruptured, allowing the fluid inside the eye to leak out. Treatment of globe rupture involves immediate surgical repair to prevent further damage to the eye.
3. Retinal detachment: This is a separation of the retina from the underlying tissues. Retinal detachment can cause hypotony by disrupting the flow of aqueous humor. Treatment of retinal detachment involves surgical repair to reattach the retina to the underlying tissues.
4. Endophthalmitis: This is an infection of the inner tissues of the eye. Endophthalmitis can cause hypotony by reducing the production of aqueous humor and increasing the outflow of fluid from the eye. Treatment of endophthalmitis involves the use of antibiotics and surgical drainage of the infected tissues.
5. Ciliary body dysfunction: The ciliary body is responsible for the production of aqueous humor. Dysfunction of the ciliary body can cause hypotony by reducing the production of aqueous humor. Treatment of ciliary body dysfunction involves the use of medications to stimulate the production of aqueous humor.

Management of hypotony involves treating the underlying ocular disorder. In some cases, surgical intervention may be necessary to repair the damage to the eye. Treatment of hypotony can involve the use of medications to increase the production of aqueous humor, such as pilocarpine or carbachol. In severe cases, a surgical procedure called a trabeculectomy may be necessary to reduce the drainage of fluid from the eye and increase the IOP.

In conclusion, hypotony of the eye can be caused
