According to the 1987 National Epidemiological Survey of Blindness and Low Vision, the prevalence of blindness in China was 0.43%, resulting chiefly from cataract (41.06%), corneal diseases (15.38%), trachoma (10.87%), and glaucoma (8.80%); the prevalence of low vision was 0.58%, of which the main causes were cataract (49.83%), ametropia/amblyopia (14.98%), trachoma (9.55%), corneal diseases (8.48%), chorioretinal diseases (6.27%), etc. Among children under 14 years of age, the leading cause of blindness and low vision was hereditary diseases (48.46%), and among the elderly of 60 years and over, the leading cause of blindness and low vision was cataract (73.13%).

An epidemiological survey of blindness was carried out in Kaipin County of Guangdong Province during October 1989 to May 1990, by stratified random cluster sampling. The sample population was 11,588, and the rate of blindness was 0.216%. The prevalence of blindness in persons aged 60 years and over was 48 times those of all other age groups combined. Since cataract accounted for 64% of the total blind cases, hence it was the key objective for surgical restoration of vision. Among 109 patients who were operated on for cataract, 83 cases were re-examined a half year later, and 78 cases (94%) had vision over 0.05.

Among 10,686 cataract operations performed in Guangdong province from 1988 to 1989, 80.16% of the patients were over 55 years of age, the ratio of female to male was 1.37:1, and 53.76% were peasants, mostly little educated. Blindness was unilateral in 55.46%, bilateral in 38.83%, and low vision in 5.71%. The mode of operation was intracapsular in 68.83%, extracapsular in 25.77%, and couching in 0.52%. After operation, 50.20% of the patients were restored useful vision, and 45.25% saved from disablement, the total success rate being 95.45%. 2.13% were ineffective and 2.14% had complications. The curative effects were up to the standards stipulated by the National Federation of Disabled Persons.

Cataract of uveitis is difficult for extracapsular extraction (ECE) because of posterior synechiae. 21 cases (24 eyes) of the cataract were performed modern ECE with satisfactory results. Postoperative visual acuity was 0.1 or better in 20 eyes, and 0.5 or better in 7 eyes. The optimal time for the operation and the procedures were discussed. The authors opined that removal of the cataract could prevent recurrences in some severe refractory cases of uveitis.

Fluorescein leakage into the anterior chamber (AC) and from the iris were found early after extracapsular cataract extraction (8 eyes) and IOL implantation (29 eyes). The leakage into AC and from the iris were apparently comparable after ECCE, whereas the former was stronger after anterior or posterior chamber IOL implantation, and no leakage was discernible where the iris and the loops of AC-IOL were in contact. Fluorescein leakage into the AC and from the iris indicated overall traumatic damage to the blood-aqueous barrier.

Twenty-five cases of posterior chamber IOL implantation in traumatic cataract with complications associated with primary injury were reported. The operating methods were described and the post-operative complications were discussed. Seventy-two percent of patients have the correct vision over 20/40. It is suggested that the posterior chamber IOL can be implanted in traumatic cataract with some injured complications.

During the period from 1980 to 1991, Radial Keratotomy (RK) had been done by the author under topical anesthesia in more than 10,000 cases, mostly on both eyes at the same time. Those patients had myopia with a preoperative refractive error between 1.5 and 20.0 diopters (D). The surgical technique consisted of 4, 8, 16 incisions using a diamond knife with micrometer and the diameter of the central clear zone was mostly 3.0 mm and determined by preoperative refractive error. Many different procedures were tried to improve the effect of RK, including redeepening intentional microperforations at 1.5 mm, 3 mm, 5 mm distance from the corneal center. But these procedures had no significant effect 6 months after the operation. Complications such as infection, glaucoma, cataract, etc. were almost none. Results of RK on long term follow up showed hyperoptic tendency, and the visual fluctuation were none or minimal.

Outpatient cataract surgery, in particular employing phacoemulsification, has now become established practice in Germany. It is as safe as the inpatient procedure but for most cataract patients less stressful, cheaper and associated with shorter waiting lists. As experience in more than 2,500 cases has shown, the outpatient procedure is fully acceptable--also with respect to complications.

During a 5-year period, phacolytic uveitis was diagnosed in 202 eyes of 151 dogs admitted to the veterinary teaching hospital. The diagnosis of phacolytic uveitis was based on the finding of a cataractous lens and anterior uveitis, unassociated with other identifiable causes of uveal inflammation. The most commonly affected breeds were the Toy and Miniature Poodle (35%) and the American Cocker Spaniel (19%). The mean age was 7.0 years for all breeds, 5.1 years for the Cocker Spaniel, and 9.0 years for the Poodle breeds. Evidence of cataract resorption was visible in 72% of the eyes. Fifty-one dogs were affected bilaterally and 100 dogs unilaterally. The mean interval between recognition of the cataract and the onset of lens-induced uveitis (LIU) was 17 months; mean times of 25 and 11 months were seen in the Poodle breeds and American Cocker Spaniel, respectively. The mean age of dogs requiring greater than 1 revisit before the inflammation had subsided was 5.5 years. Complications, referable to the uveitis, were seen in 14% of eyes, the most important of which were glaucoma (16 eyes) and phthisis bulbi (9 eyes). Lens extraction surgery was done on 50 LIU-affected eyes, and on 35 normal eyes in LIU-affected animals. The 2- and 6-month success rates for LIU-affected eyes were 78 and 39%, respectively, and for normal eyes in LIU-affected animals were 85 and 71%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

This case study reports on a 64-year-old female who presented for cataract surgery. She relayed a history of allergic responses to local anesthetics such as xylocaine, but was otherwise in good health. Upon instilling ophthalmic preparations into her eyes during routine ocular examination, she developed general muscular weakness but not other allergic-like symptoms. Further investigation established her myasthenic-like syndrome to be precipitated by an ophthalmic mydriatic preparation. She was able to undergo uneventful cataract surgery and enjoy 20/20 vision postoperatively, with proper management.
