Bupivacaine 0.5% when used as a local anaesthetic for ocular cataract surgery does not give absolute ocular akinesia but provides adequate and prolonged pain relief. In comparison lignocaine provides good ocular akinesia at operation but pain relief is short lived. The mixture of the two local anaesthetics in equal volumes eliminated the disadvantages of their individual use.

In a double-blind, between-patient trial, a new cyclo-oxygenase inhibitor, pirprofen (800 mg/day), was compared with indomethacin (100 mg/day) and placebo in 56 patients undergoing cataract extraction. Treatment started 48 h before operation and continued for eight days. Patients were examined on days 1, 3 and 6 for objective signs of inflammation and pain. Both active drugs proved to have good anti-inflammatory action, clearly superior to placebo. No unwanted effects or modifications in laboratory parameters other than those related to the antiphlogistic effect were reported.

Three groups of 15 patients each were randomly assigned to receive a retrobulbar anesthetic block with 0.5% bupivacaine, 0.5% bupivacaine/2% lidocaine or 0.5% bupivacaine/2% lidocaine/1:100 000 epinephrine for unilateral cataract surgery. Hyaluronidase was added to each of the preparations, which were used in double-blind fashion. Lid and globe akinesia and corneal anesthesia were graded after 4 minutes of ocular massage and 36 minutes later (at the end of the procedure) to assess the rapidity of onset and the duration of action of the anesthetics. Overall, bupivacaine/lidocaine/epinephrine was the most effective in producing akinesia of the lids and globe. Bupivacaine alone was more effective than bupivacaine/lidocaine without epinephrine in producing akinesia, although it was slower in producing anesthesia. There was no difference between the groups in the frequency of pain or of the need for analgesia 6 hours postoperatively.

If the theoretical advantages of krypton laser over argon laser are proven clinically, this modality will be an important adjunct in the management of many of the leading causes of blindness. Our preliminary observations in over 400 cases treated with krypton laser correlate well with the theoretical and histopathologic observations of others. Possible advantages of krypton laser therapy for choroidal neovascularization (CNV) include its ability to penetrate foveal xanthophyll and retinal blood vessels and to minimize damage to the nerve fiber layer. Krypton also penetrates the xanthochrome in nuclear sclerotic cataract. The major disadvantage is increased choroidal hemorrhage. In proliferative retinopathies krypton penetrates moderate vitreous hemorrhage. It may minimize both epiretinal membrane changes and continuation of vitreo-retinal traction. It can be used after fluorescein injection. Disadvantages include increased choroidal hemorrhage and increased pain, often requiring retrobulbar anesthesia. Krypton laser cannot close surface neovascularization or stop bleeding by photocoagulating its source. The role of argon laser in CNV or how it benefits proliferative retinopathies is still not understood. The Macular Photocoagulation Study will help define the role of argon and krypton laser for CNV. A similar clinical trial to compare the efficacy of krypton laser to the proven efficacy of argon laser in the treatment of proliferative diabetic retinopathy is still anticipated.

The present study is a two year-follow up of 105 eyes (including 27 aphakic eyes), operated on retinal detachment by silicone oil injection after pars plana vitrectomy. This procedure was chosen either as an initial treatment (37 eyes) or after a classical treatment by external indentation had failed (68 eyes). All cases of retinal detachment were of bad prognosis: macular hole, massive periretinal proliferation, isolated or associated with a tear. Cases of vitrectomy with silicone injection for proliferative retinopathy due to diabetes or hemoglobinopathy were excluded. Operations were performed under a surgical microscope with the help of a corneal contact lens (Goldmann, Kl oti or O' Malley ). Functional and anatomical results, as well as complications, were evaluated at least 2 years after treatment. In 24,7% of cases, vision was improved as compared to preoperative visual acuity. Cataract was a constant complication in all phakic eyes, as silicone oil had not been removed within the first 6 months. Intraocular hypertension developed frequently both in phakic and in aphakic eyes (29,5 and 33% of cases, respectively) and responded poorly to medical or surgical treatment. Other complications occurred less frequently. They were corneal edema, conjunctival hyperemia and uveitis. Pain imposed the evisceration of 2 eyes. These complications were the consequence of silicone oil toxicity and/or the mechanical effects of intraocular oil. Besides treatment-associated complications, early (36 during the first 6 months) as well as late (2 between the 12th and 18th months) recurrences of retinal detachment were observed. In contrast to these fair functional results, anatomical results were good in most cases.(ABSTRACT TRUNCATED AT 250 WORDS)

A 75 year woman with chronic vitreous hemorrhage underwent extraction of a senile cataract. Surgery was complicated by the flow of brown fluid from the vitreous to the anterior chamber, which was not entirely removed. Post-operatively there was pain, 2 mm of brown hypopyon and intraocular pressure elevation to 60 mm Hg with the preoperative diagnosis of endophthalmitis, a pars plana vitreous tap and instillation of intravitreal antibiotics was performed. Bacterial cultures were negative and the presence of erythrocyte "ghost cells" established the diagnosis of hemolytic glaucoma. As medical management proved ineffective, a pars plana vitrectomy was performed. One year post-operatively the patient had a visual acuity of 0.4-0.5, normal intraocular pressure without medication and evidence of an old branch retinal vein occlusion. The mechanism of hemolytic "ghost-cell" glaucoma in this case is discussed.

Electrical skin resistance on Accumulation points in twelve meridians was measured during operation of cataract under local anesthesia. Electrical skin resistance increased an average of 15 percent in bladder, kidney, liver, stomach, gall bladder meridians, and decreased an average of 18 percent in lung, small intestine, heart, spleen-pancreas, heart constrictor, triple heater, large intestine meridians. When comparing the skin resistance values with those under acupuncture anesthesia during ophthalmic surgery, the skin resistance value under acupuncture anesthesia exhibited a marked decrease in all meridians (average 23 percent decrease) except the kidney meridian. On the other hand, the skin resistance under local anesthesia was only a 7.4 percent decrease in all meridians except the kidney meridian. It was speculated as one of the reasons for less changes of skin resistance under local anesthesia that sympathetic nervous activity did not occur so much because of pain relief due to local anesthesia.

Candida endophthalmitis developed in the left eye of a 71-year-old man two months after he underwent extracapsular cataract extraction and intraocular lens implantation. The symptoms included decreased vision and redness but no pain. The discovery of the cause of the endophthalmitis was delayed because it was initially treated as a sterile postoperative inflammation. Vitrectomy with intracameral amphotericin B and treatment with topical and systemic amphotericin B and flucytosine led to resolution of the infection and a final visual acuity of 20/80. It was not necessary to remove the intraocular lens.

Exposed monofilament suture ends caused a variety of symptoms and signs in 18 patients. These included foreign-body sensation, pain, contact lens intolerance, giant papillary conjunctivitis, tarsal ulceration, conjunctival granuloma, corneal infiltrate, and corneal vascularization. These changes followed cataract surgery, corneal transplantation, and pars plana vitrectomy. Diagnoses in these cases were made by careful slit-lamp examination and by eversion of the upper eyelid. In every case, removal of the sutures or trimming the suture ends resulted in the immediate relief of all symptoms with complete resolution of all signs within two months.

In this double-blind study of retrobulbar block for cataract surgery, 62 patients scheduled for cataract surgery were randomly assigned to treatment with either (1) lidocaine 2% with epinephrine 1:200,000 (21 patients); (2) etidocaine 1% plain (20 patients); or (3) etidocaine 1% with epinephrine 1:200,000 (21 patients). The time of onset of sensory and motor block after administration of the three drugs was the same. The duration of motor nerve block produced by etidocaine plain and by etidocaine with epinephrine was considerably longer than that produced by lidocaine with epinephrine, and fewer patients reported postoperative pain after either etidocaine plain or etidocaine with epinephrine than after lidocaine with epinephrine.
