Abstract:
Purpose To report the various types of glaucoma among West African patients presenting to an eye clinic in Ghana. Methods A complete evaluation was performed in 198 consecutive Ghanaian glaucoma patients. Main outcome measures included intraocular pressure, visual acuity, gonioscopy findings, visual field, and total number of glaucoma medications. Results The most common form of glaucoma was primary open-angle glaucoma (44.2%). Open-angle glaucoma suspects also comprised a large percentage of the group (30.5%). Chronic angle-closure glaucoma was diagnosed in 6.6% of the patients. Conclusions Primary open-angle glaucoma is the most common form of glaucoma being treated in this outpatient eye clinic in Ghana. Chronic angle-closure glaucoma was the second most common form of glaucoma in this series and was usually undiagnosed due to a lack of gonioscopic evaluation. Gonioscopy is an important diagnostic tool that should be promoted to guide more effective glaucoma treatment in this region. Pseudoexfoliation and pseudoexfoliation-associated glaucoma were not seen in this population.Keywords:

One hundred eyes which had undergone extracapsular cataract extraction with no iridectomy followed by insertion of a posterior chamber lens were examined gonioscopically 1 to 4.7 years postoperatively to determine the prevalence of asymptomatic angle closure from pupillary block. Since no peripheral anterior synechiae (PAS) characteristic of pupillary block were found, there seems to be little risk that these eyes will develop angle-closure glaucoma. During the study small PAS were noted adjacent to many haptics implanted in the ciliary sulcus.

Objective The reason of high intraocular pressure after excision or Laser Iridectomy on operation of peripheral iris.Methods Nasal above clear corneal incision line iridectomy,Nd:YAG laser iridectomy with local iridoplasty by krypton laser in nasal 11:00。Postoperative intraocular pressure,angle,depth of anterior chamber and anechoic chamber tests,Found in cases with high IOP peripheral iridectomy zones、gonioscopy and understand its causes.Results In all cases,there were 3 eyes with remained pigained in peripheral hole,6 eyes and anterior chamber angle examination in diagnosis of less accurate,Plateau iris in 4 eyes,Narrow-angle and open-angle glaucoma 4 eyes,mixed glaucoma 2 eyes,In a variety of mechanisms 10eyes.Conclusion Except for choosing the proper surgical and accurate chamber angle examination。It is very important to check the IOP depth of anterior chamber,gonioscopy and irritation tests to get the early diagnosis and management.

We aimed to test the hypothesis that there is an association between hypothyroidism and primary open-angle glaucoma. A total of 60 patients with acquired hypothyroidism were evaluated by a senior ophthalmologist for evidence of glaucoma. Evaluations were carried out by history, tonometry, funduscopy, gonioscopy and visual field perimetry. Thyroid function tests, and dermatological and neurological examinations were performed. Patients were matched according to age and gender. There were 10 males and 50 females (age range 34-72 years). We found 3 of the 60 patients had signs of open-angle glaucoma, which indicated a possible relationship between hypothyroidism and open-angle glaucoma. It is worth expanding the study to a larger number of patients.

Minimally invasive glaucoma surgery (MIGS) provides a safe option for individuals with mild to moderate open-angle glaucoma to reduce their need for pharmacologic therapy or more extensive ab externo surgeries. In this report, we describe a surgical technique using both the Kahook Dual Blade and Gonioscopy-assisted transluminal trabeculotomy (GATT), to treat a 23-year-old active duty female with idiopathic uveitis and subsequent corticosteroid-induced glaucoma who presented with consistently elevated intraocular pressure (IOP) measurements despite maximal pharmacologic interventions. This combination was effective in consistently lowering intraocular pressure for at least 12 months in a young, phakic, active duty patient with uveitis and steroid-responsive open-angle glaucoma.

Gonioscopy is indispensable for proper diagnosis and management of angle-closure glaucoma. Conventional methods of gonioscopy provide a static image of the configuration of the angle at the particular moment of examination. The extent of occlusion may be determined, but appositional closure cannot be accurately distinguished from synechial closure. This distinction is of considerable importance since an iridectomy is more likely to be successful where synechial closure is minimal. In 1957 Shaffer proposed a method of operating room gonioscopy immediately after peripheral iridectomy in order to determine the degree of peripheral anterior synechia formation.1It was based on the premise that appositional closure is reversible and largely eliminated by peripheral iridectomy, whereas synechial closure is irreversible. If most of the angle is found to have opened by virtue of the iridectomy, then the operation is terminated. If extensive adhesions are noted, the surgeon either converts the iridectomy to a filtering

Objective To observe the influence of acupuncture combined with eyedrops on the intraocular pressure in the patients with primary open-angle glaucoma and difference of curative effects between this therapy and eyedrops.Method The patients with primary open-angle glaucoma(n=49,86 eyes)were randomly divided into the treatment group treated with acupuncture combined with eyedrops and the control group treated with eyedrops only.The indexes of intraocular pressure were detected and compared in the patients of two groups before and after the treatment.Result The intraocular pressure was significantly different in the patients of two groups after the treatment than before(P0.05).In the treatment group the intraocular pressure in patients after half year was also significantly different after the treatment than before(P0.05).Conclusion The therapy of acupuncture combined with eyedrops can reduce the intraocular pressure in the patients with primary open-angle glaucoma.
