Recommendation Statement “glaucoma affects approximately 2.5 million Americans and is a leading cause of impaired vision (loss of peripheral vision) and blindness” (Moyer). Glaucoma is a disease the damages the optic nerve in the eye. There are several different types of glaucoma including: Open-angle, normal-tension, closed-angle, and congenital glaucoma. Open-angle is the most common. Even though there is no treatment yet for glaucoma, a person can manage it. To help a person mange this disease there are two basic treatments that can be used: medicated eye drops or surgery.

No statistically significant differences in terms of clinical KSS and KOOS scores between analyzed groups; this was observed for the percentage of MA outliers. The percentage of implant revisions was slightly higher in Group B than in Group

During my high school career, I became fascinated with the workings and functions of our eyes while attending an internship at an ophthalmologist's office. Through my time there I was fortunate to be able to shadow and assist both the ophthalmologists and optometrists. While taking corneal topographies of patients' eyes before they were examined, my interest continued to grow and that interest blossomed into a desire to pursue this as a career when I had the opportunity to witness my first eye surgery. Though the pterygiectomy was a simple procedure, I was inspired by the fact that it could allow the patient to see better, changing their life.

The patient recovery is uneventful. The patient is alive and well at the one year follows up, with no clinical evidence of local

evaluated 217 patients at a single institution who were dichotomized between minimally invasive (MA) versus conventional strategy (GA).32 They found that MA patients had shorter length of stay (3 vs. 6 days, p<0.001), an equivalent survival rate at 230 days, and a decreased cost of $16,000/case.32 Babaliaros et al. echoed these results, showing decreased operative time, ICU time, overall length of stay, and overall costs without differences in 30-day or 1 year mortality.8 D’Errigo et al. observed no difference in 30-day or 3 year mortality rates using the OBSERVANT study data in Italy.42 The Rouen group studied 151 patients prospectively over 5 years and determined TAVR implantation under local anesthesia and fluoroscopy alone to be safe and feasible, with conversion to GA in

At first, the surgery seemed to be successful. But several hours later, the patient’s condition began to deteriorate, and it continued to worsen over the next few days.

The eye retention is one of the main goals of the conservative treatment, but in some cases enucleation can be indicated due to complications after therapy e.g. secondary neovascular glaucoma (Furdova et al. 2005).

Eye: patient’s states having “Annual eye examination for 5 years, Glasses for driving, inability to see far object (myopic). Patient was able to read with each eye and both eyes with eye glasses. There was no abnormities with cranial nerve 2, 3, 4 and 6. Pupil was equal round, reflective to light and accommodation.

In these cases, the angle between the iris and the cornea is too small, which results in the build up of aqueous fluid pressure that pushes the iris forward blocking the trabecular meshwork causing increased intraocular pressures. LPI helps open up the angle to increase fluid outflow and lower the pressure. For patients with narrow angle glaucoma this is also a preventative measure to stop the development of acute narrow angle glaucoma attacks, which present with pain, high intraocular pressure and loss of vision within a couple of days if left untreated. During LPI a a very minute hole is made with the laser beam in the superior periphery of the iris the coloured part of the eye. This helps open up the narrow angle so the aqueous humor can flow forward through the new hole (Chen 2003). The end result is re-balancing the pressure between the posterior and anterior chambers and letting the iris go back to a more plantar position that takes pressure off the trabecular

Eyesight is the most important of the five senses. The world today revolves around being able to see and understand things. As the average age of the world continues to increase, glaucoma has become increasingly prevalent in the population. Glaucoma currently affects around sixty million people worldwide and is expected to affect eleven million people in two thousand twenty(Mohammadi et al. 3). Losing the gift of sight is unbearable to most people, but glaucoma can be treated if it is caught early enough.

The prevalence has been calculated to be between 0.06% and 0.1%. A nanophthalmic eye is normal in shape but unusually small, with a shortened axial length (<20 mm), a small corneal diameter and a relatively large lens for the volume of eye. Other findings in nanophthalmic eyes include a shallow anterior chamber both centrally and peripherally, an anteriorly displaced iris, high hyperopia, thick sclera, spontaneous and postoperative uveal effusions and a wide pulse pressure. A subset of patients with familial, recessive nanophthalmos also have a pigmented retinal degeneration. Spontaneous choroidal effusions can occur that may induce angle closure glaucoma. Pupillary block related to age and to lens swelling is a factor in some. The effusion rotates the ciliary body anteriorly, displaces the peripheral iris, and loosens the zonules, allowing the lens to move

Cataract has been known to mankind for many centuries, and cataract surgery for many years has enabled people to recover their vision, this assignment will be focusing on the different cataract surgery over the years the advantages and disadvantages plus on certain occasions the masterminds behind the innovations. Firstly it’s important to define cataract; a cataract is a cloudiness or opacity in the normally transparent crystalline lens of the eye. This cloudiness can cause a decrease in vision and may lead to eventual blindness. The word cataract has been derived from Greek origin which means waterfall. The original name was of Latin medicine but was lost in translation of Arabic writing s which was suffusio which was a short hand to

As discussed before, vitreous humor (VH) is a transparent gel (Chirila and Hong, 1998) , rich in hyaluronic acid and unbranched collagen Type II fibrils (Scott, 2003) which fills the posterior cavity of the eye. The hyaluronan content in the vitreous humour is higher than the protein content and plays an integral role in maintaining the internal tension (Kummer et al., 2007) of VH by a process called Donnan swelling (Kleinberg et al., 2011). Several materials have been tested as substitutes for VH, each of them serving either of the main purposes as described. The implants may either be used to replace a dysfunctional VH when opacification or physical collapse of the original structure has occurred or they may have a temporary or permanent

In every study, a general, overarching theme prevails in the conclusions. DC increased likelihood of poor outcome (Cooper et al., 2011). Many complications arose from normal changes that occur after surgery, meaning that certain factors don’t necessarily indicate that certain patients to have a poor outcome. In all studies across the board, similar percentages of complications were recorded even with different populations, so age/population might not have an effect on complication rates (Stiver, 2009). Contusion expansion and age are significantly predictive of death from DC. Subdural effusion was significantly associated with low postop death risk (Ban et al., 2010). The study found that age, anisocoria,

The concept of EDOF with IOLs was described more than two decades ago. Nakazawa and Ohtsuki informed apparent accommodation of approximately 2.00 D in 39 eyes implanted with spherical IOLs in 1984. The authors also measure each patient's pupillary diameter, anterior chamber depth, and corneal refractive power to analyze the influence that characterizes the depth of field. The writers found a important correlation between deceptive accommodations and depth of field.
