1. What is Glaucoma? Glaucoma is a series of conditions, characterized by a particular form of optic nerve damage that is often-but not always- associated with elevated IOP. The American Academy of Ophthalmology now defines glaucoma as “a group of diseases with certain features including an intraocular pressure that is too high for the continued health of the eye.”

57. Glaucoma types: stats In US Open angle glaucoma 80% Angle Closure Glaucoma 20% 50% from narrow angles 40% from plateau 10% from lens rise
58. Evaluating Angles Most important anatomic landmark is the scleral spur can be seen an the innermost point of the line separating the ciliary body and the sclera. The trabecular meshwork is located directly anterior to this structure.
59. Narrow Angles relative pupillary blockis most common cause aqueous pressure behind the iris plane forces the iris anteriorlygiving it the typical convex appearance Indentation gonioscopy will flatten iris and open angle Definitive treatment is peripheral laser iridotomy
61. Plateau Iris Not all angle-closure is caused by relative pupillary block Patients with plateau iris tend to be female, in their 30-50s, hyperopic, and often have a family history of angle-closure glaucoma Slit lamp examination of patients with plateau iris usually shows normal anterior chamber depth with a flat or slightly convex iris surface. On gonioscopy, the angle is extremely narrowed or closed, with a sharp drop-off of the peripheral iris.
62. Plateau Iris Plateau Iris is due to anteriorly positioned ciliary processes, which hold the peripheral iris forward The anteriorly placed ciliary body forces the peripheral iris into the angle. In Plateau Iris, the angle remains occludable with a patent iridotomy
63. Plateau Iris When indentation gonioscopy is performed, the double-hump sign is seen. The more peripheral hump is determined by the ciliary body propping up the iris root, and the more central hump represents the central third of the iris resting over the anterior lens surface. The space between the humps represents the space between the ciliary processes and the endpoint of contact of the iris to the anterior lens capsule. More force often is needed to open the angle on indentation gonioscopy than on pupillary block angle closure.
64. Plateau Iris Plateau iris syndrome is characterized by persistent angle occludability (spontaneous, in the dark, or after dilation) in an eye with a patent iridotomy More commonly, the diagnosis of plateau iris configuration is made on routine examination. Plateau iris syndrome usually is recognized in the postoperative period when the angle remains persistently narrow in an eye after iridotomy
65. ALP: Argon Laser Peripheral Iridoplasty the procedure of choice to effectively open an angle that remains occluded after successful laser iridotomy The procedure consists of placing laser burns on the surface of the peripheral iris to contract the iris stroma between the site of the burn and the angle Peripheral location of long-duration, low-power, large spot size laser burns is essential for success The result is iris stromal tissue contraction and compaction that physically widens the angle and prevents the apposition of the peripheral iris against the trabecular meshwork ALPI is highly effective, and the effect is maintained for years
66. Lens Intumescence..Lens Rise A large, intumescent lens or forward lens movement due to zonular laxity or dehiscence may cause mechanical crowding of the angle Diagnosis is based on shallow AC, narrow angles, Patent PI, narrow AC and short AXL in hyperopic individuals Treatement is clear lensectomy More and more lensectomies are taking the place of chronic glaucoma therapy for these patients

116. Integrated Eye Care vs Co-management integrated eye care model: optometrists, ophthalmic technicians, and ophthalmologists all work under the same roof to provide efficient and effective patient care Co-management model: practices refer patients across boundaries and leave the optometrist as the primary care physician to handle a majority of eye care integrated eye care is likened to a vertical integration in the same practice, and co-management comprises different practices where both jointly manage the patient
117. Advantages of Integrated Eye Care Optometrists have readily available access to specialty care for their patients The patient already knows the practice and doesn't have to travel further to go see a specialist, or worry about not being familiar with the practice working in an integrated practice can be a great learning experience Since everyone on staff has access to all the charts, there's an immediacy co-managed practices cannot offer. ability to control the quality of care because everyone is under the same roof

Key Discussion PointsOcular allergy—specifically, seasonal allergic conjunctivitis—shares many features of underlying inflammation with other forms of ocular surface inflammatory disease1While it is typically not vision-threatening, SAC can cause considerable discomfort and, in some patients, morbidity and lost productivity2References Abelson MB, Smith L, Chapin M.
